EQUIPMENT FOR NON--SURGICAL LOCKING OF A EILEITERS

In the area of birth control the Empfängnisverhütung is substantially more suitable than the abortion, in order to steer the growth of the population. The methods suggested existing for the purpose to the Empfängnisverhütung or are subject restrictions regarding their applicability and their effectiveness. Each Empfängnisverhütung should be effective 100%ig, it should the sexual relations not impair and it should be cheap with consideration of the effective duration of the effectiveness of the empfängnisverhütenden means. The Empfängnisverhütung should furthermore no physiological or psychological side effects have and it should be reversible. Such means such as condoms, diaphragm or Vaginal foam are to a considerable degree unreliable. Devices, which are inserted into the Uterus, are limited regarding their application and often cause irritations, inconveniences and heavy bleedings. In addition they can be discharged without knowledge of the Trägerin, which can lead to the pregnancy. The empfängnisverhütende pill disturbs the normal hormone equilibrium and the more their side effects admits, their applicability is all the more limited. There is at present two methods well-known, which are regarded as effective empfängnisverhütend. These are the Eileiter Ligation (including electrical prevention and rubber band methods) for women and Vasektomie for men. In both cases the Eileiter become and/or. Samenleiter split or interrupted and these methods are effective, if they are accomplished correctly, 100%ig (whereby no natural regeneration arises). Both methods require however a medical interference and them are difficult both, if not impossible to turn around i.e. a normal procreativeness or capable of child-bearingness is no longer attainable. It is well-known that a principal reason for the Unfruchtbarkeit is with women the blocking of the Eileiter from the Uterus. The egg is absorbed, if it one pushes off, by the body and it is prevented to come into contact with closing so that no Empfängnis takes place. Women, who have this condition from nature, do not recognize this condition normally at all and it are no side effects, apart from which Unfruchtbarkeit, well-known. From there already numerous methods and devices were suggested, in order to close the Eileiter, in order to reach a sterilization. None of these well-known methods can be turned around and/or eliminated without medical and/or surgical interference again. Such methods, which do not require a surgical interference, are not 100%ig effectively. Furthermore the empfängnisverhütende method should be surely, reliable and cheap. Furthermore an express pus potting is to be created, which is reversible, without fluoroskopische techniques must be used. Finally usual operation Hysteroskope is to be used to be able. In accordance with the invention this reached by the formation of express pus potting, which prevent a Empfängnis and which can be removed in non-surgical way again. The device covers a standard Hysteroskop, by which a pair of concentric tubes is used, whereby the internal tube carries a catch point. The catch point is aligned with the Uterusende of the Eileiters and a mixture from fluid elastomers a material and a catalyst for polymerizing the material is inserted visually by an opening in the point into the Eileiter. Catalyzed elastomers firm the material lets one and at the point will adhere. The point solved when pulling out the internal pipe (by the limiting effect of the outside pipe) and it remains to integral with the hardened, elastomers material, in order to form the express pus potting after the invention. The Hysteroskop is then taken out. That express pus potting can be removed in a non-surgical way again, as the same or a similar Hysteroskop is again introduced and a grab element is introduced for seizing the point by the channel of the Hysteroskops, whereby the plug is removed and the fertility is restored. Therefore the invention concerns an equipment for non-surgical locking of a Eileiters with the help of elastomers of a plug formed on the spot, which is characterized by the combination an operating channel exhibiting Hysteroskops with a pair essentially itself flexible plastic of pipes extending equivalent far in telescope arrangement, those by the operating channel hindurchbzw. is importable, whereby by the internal pipe a fluid catalyzed elastomer material hindurchbzw. is importable, and with a mechanism for mixing the elastomers the material with the catalyst and to the Hindurchbzw. Would bring in catalyzed elastomers of the material by the internal pipe under given pressure, as well as with outside mechanisms appropriate at the Hysteroskop solvable locking of the internal pipe and the exterior the pipe in non-adjustable way relative to each other, whereby with the release of locking the internal pipe is telescope-like regarding the outside pipe under release of the plug adjustable. In the US-PS No. 3.805.767 similar a in principle device is descriptive, from l0 which however the equipment according to invention differs that it, in an appropriate way adapted, is combined with a Hysteroskop. In accordance with the US-PS No. 3.805.767 the device described there is preferably introduced and aligned using Fluoroskop techniques, it could not be thus at all so small and flexible that it in confined and curved operating channel of a Hysteroskops is fit in and function also correctly could. After their nature the well-known device is not flexible, so that it can be used into the Uterushohlraum either “blindly” or evenly only with the help of fluoroskopischer methods. For example execution forms of the invention are described on the basis the designs in detail, in the Fig.1 schematically a Hysteroskop with catch point and konzenirischen telescope tubes in position in an operation channel show in the following. Fig.2 points the catch point in the detail in its arrangement to the concentric tubes. Fig.3 shows schematically arrangement and formation of an express pus potting. Fig.4 shows schematically work procedures similarly those after Fig.3 with another execution form, with which no catch point is used. Fig.5 points Mischund distribution equipment to mixing and delivering the elastomers the fluid material and the catalyst. Fig.6 shows schematically a mechanism, in order to bring the catalyzed, but still unhardened elastomers material to flowing. Fig.7 shows schematically Hysteroskop and Uterus with the application of the invention. Fig.8 shows an alternative arrangement, in order to introduce the elastomers the material. After the invention an express pus potting in the Eileiter is formed on the spot, which plugs preferably formed from a medically inert polymer (elastomer), that approximately the same modulus of elasticity after the hardening by precipitation has as the Eileiter. The selection of the suitable modulus of elasticity for the hardened plastic helps to prevent discharging and avoid physical inconveniences. A suitable material are commercial silicone elastomers of medical quality, as e.g. endverblocktes hydroxyl Poly Dimethylsiloxan, which contain Propylorthosilicat as cross linkage material, as well as a silica filling means (Diatomeen-Erde) in a concentration of 23 Gew. - %. With mixing with tin (II) - Octoat begins the cross linkage material with the splitting up of Propanol without education of noticeable warmth. Another such material is Silphenylen polymer, which is similarly hardened. Into the composition a röntgenstrahlendurchiässiges material is appropriately built, like e.g. fine pulverized spherical silver powder (grain size under 40 pm), barium sulfate or Wismuthtrioxid, in order to make an observation possible of the plugs on the spot by X-ray. Before the networking the plug forming composition a diluent is appropriately added, in order to reduce the viscosity. (The descriptive material has a viscosity of approximately 5000 Pa.s). A suitable diluent is a endverblocktes Poly Dimethylsiloxan with a viscosity of approximately 0.2 Poise. The catch points are appropriately manufactured by forms. They consist of a material similarly the plug, however without diluents for the viscosity reduction. A catch point is in the Detaßl in Fig.2--20--represented. The surface --21-- it is in such a way formed that she fits as tightly as possible the Uterusende of the Eileiters (Fig.3A). A channel trained in the point --22-- permits the passage of the elastomer material, whereby the channel --22-- outward to narrow itself can, in order to make possible a mechanical (and integrals) connection with hardened elastomers the material, e.g. as in the Fig.3C and 3D is shown. The internal dimension of the catch point is somewhat smaller than the external dimensions of the pipe --30--, on which it mount (after it was somewhat stretched). A federation --23-- at the catch point --20-- in the dividing line during the shaping and appropriately maintained, there he is trained the structural firmness of the point during their aspect ratio over the tube --30-- increased. For easier seizing of the catch point and the integrals the plug (during hardening one forms), is a polyester thread --24-- embedded, as Fig.2 shows. The thread consists about 0.2 mm in diameter of a white vielfädigen Äthylenterephthalat and ungepreßt. The thread can be covered with a silicone rubber, like e.g. an air-hardening l0 medical adhesive. It can have the form of a closed loop alternatively, as for example is shown in Fig°3D, or it can be completely into an extended piece of the catch point (not shown) embedded. With the training as free loop either a usual blunt hook or pliers can be introduced by the operating channel of the Hysteroskops for seizing. With the embedded execution form pliers are used. Since the use of blunt hooks and pliers admit by the operating channels of Hysteroskopen are, this is not in detail described. It is a characteristic of the invention that adheres selected elastomers to material only at other silicone rubbers, not however at the human fabric, at the tube --30-- or other materials, except by mechanical anchorage in case of a porous substrate. Since the fabric, within which it rests or lies close, lies i.e. the Eileiter, locally outside (like e.g. mucous membranes), has the plug rather a mechanical as an adhesive nature and the block covers or plug or over-crosses no fabric lines. The body does not regard it from there as foreign body and the plugs is not discharged. Fig.1 shows a usual Hysteroskop with a normal operating channel --10-- of approximately 2.3 mm inside diameters and about 30 cm length. With the methodology of the invention are compatible ACMI instruments with 6 to 7 mm of outside diameters with forward a diagonally arranged view, like by the broken lines with 11 are suggested and a lighting by a source of borrowing not shown of variable strength, whereby the light by the fiber optics tubes --12-- to the point --13-- the Hysteroskeps runs, within which in usual way the fiber optics ends and the observation lens are installed. The lens gives an increased picture to the eyepiece lens at the piece of observation --14--. The Hysteroskop made possible thus a “cold” observation of the Uterus and the catch point can be arranged in the Uterusende of the Eileiters without heating up due to the light. Furthermore the Hysteroskop has an operating channel --15--, by that the tubes --30 and 31-- run. A valve --18-- and its associated, fittings not shown make an introducing possible of an observation fluid in the Uterus before using the tubes --30, 31--, which lead the catch point and the elastomers the material. In Fig.1 the device according to invention is shown, directly before would bring in the elastomers of the material into the pipe --30-- (see also Fig.7). The catch point is, as descriptive above, at the internal pipe --30-- arranged. A slidegate valve --19-- with a flange --19 '-- is at the outside pipe --31-- installed by means of any usual arrangement, e.g. a thrust ring, in order to make a movement possible of the VerschlnBspitze at the express pus end (incl. the internal and outside tubes --30 and 31--). The tappet or slidegate valve --19-- when hardening the elastomer for it, the outside pipe furthermore serves --31-- to hold in position, while the internal pipe is pulled out, whereby the connection of the catch point with the pipe --30-- one separates. Before a detailed discussion of the method according to invention three subsystems in the detail are discussed. These cover the mixer and distributor for thorough and fast mixing of the catalyst with the elastomers the fluid, the tubes --30 and 31-- and the system to the Influßbringen catalyzed elastomers of the material. Since the developing, hardened elastomer has for instance a rubber-like consistency and because the Eileiter are extremely close (in the order of magnitude of 1 mm) are it importantly that no bubbles are enclosed in the catalyzed elastomer. Hiezu was developed a mixer and a distributor, which do not drag air along, in order to avoid such a case. The mixing unit shown in Fig.5 covers a cylindrical body --50--, in which hinund a working piston --52-- is installed. The delivering of the desktop device has an end piece --51--, like most connection points for the system. Such a connecting piece is a commercial standard available highway, which uses schraubenlinienförmigeGewinde, in order to connect hermetically fitting male and female Konen. An end cap can seal hermetically the mixer end. The liquid elastomer material becomes into the cylinder --50-- cast in, before using the piston --52--, that with friction seat in the cylinder --50-- sits. A degassing in a vacuum chamber with an overflowing judge at the end piece follows on that --51--, on which a cap is put on. The time of the use the catalyst (about 1.4 Gew becomes. - % concentration) by the end piece injected and the cap replaces. If the piston in the cylinder --50-- , is hermetically sealed he is arranged by means of a pair O-rings --53--, whereby the lower O-ring as an internal poetry and the upper O-ring as an outside poetry work. The mixture takes place via Hinund moving the head --54-- relative to the knurled mounting plate --55--, whereby a feather/spring --56-- as constant reconducting strength works. The Hinund moving arranges the mixture head --57--, that on a wave --58-- is installed to mix thoroughly and fast the catalyst and the liquid elastomer. Since in the system no air is contained, also none can be drug along. Fig.SA shows the mixture head in the detail. Mixing effectuation by the flanges --57 '-- and the channels --57 "--, whereby the relationship of the cross sections of these parts of the viscosity of the mixture depends. A relationship of for instance 50:50 proved as appropriate. Mixing should be accomplished as fast as possible, with a 1/4-turn of the head --54-- and thus the mixture head at the end of each double stroke. About 30 s mixture time are enough out for to descriptive elastomers the materials. After Vo! lendung the mixture becomes the mixture head --57-- to the pin --59-- withdrawn and by a 90°-Drehung in position locks. The whole device works then as normal syringe for injecting the materials by the end piece --51-- after decrease of the end cap --51 '--. With the device after Fig.5 it is possible to mix the components thoroughly without air is drug along and then the device into delivery equipment to switch, by simply locking of the mixture head at the piston. The device should have a volume of approximately 3 cm3, whereby the housing preferably consists of polypropylene, while the mixture head, the wave, which locking taps and the cap appropriately consist of stainless steel. The tubes --30 and 31-- consist of an inert, flexible, flexible, thermoplastiachen, preferably transparent material. For example as suitably proved, a polysulfone of medical quality, which is extruded in endless sections. The internal tube, which contains or leads the elastomer, has approximately an inside diameter of 1 mm and an outside diameter of 1 1/2 mm, while appropriate dimensions for the external pipe amount to about 1.6 mm inside diameters and about 2 mm of outside diameters. Alternatively the tubes can consist of Polyphenylsulfon, Polyearbonat, polytetrafluoroethylene, fluoriniertem ethylen propylene copolymer, polypropylene and thermoplastic polyester. Polysulfone is to that extent ideally, when it can be sterilized with steam and transparency is, it has a good combination of high tensile strength and good flexibility. Furthermore it can be strained heat treated and mechanically, so that it can receive a curvature with a radius from approximately 50 cm. This curvature contributes to set the catch point directly on the Eileiter to the full observation by the lens of the Hysteroskops (Fig.7). The polysulfone tubes --30 and 31-- become in firm relationship to each other with the help of an doubleended ring or a case --60-- (Fig.1) held, their right end under friction interference the external pipe --31-- seized, that between the cases ends and to their left end under friction interference the internal pipe --30-- seized. Up to the unblocking the two pipes work --30 and 31-- because of the doubleended case as a unit. Fig.6 shows the mechanism for the supply of the catalyzed, elastomers of material. On an extruded aluminum rail --61-- is an engine --62-- with variable number of revolutions and independent torque installs, the one movement screw and/or screw pillar --62a-- propels. The other end of the spindle --62a-- is in a crossbar --67-- for stability reasons swivelling stored. In the rail --61-- a carriage runs --63--, that with the spindle --62a-- steered to the purpose of the forward movement, by the engine --62--, is coupled. On the carriage a micrometer is firm --64-- arranged, its adjustable point --64 '-- at the end cap --54-- the mixing unit --50-- knocks against. The mixing unit is firmly concerning the aluminum rail installed, for example with the help of a connecting link--65--. Becomes the engine --62-- switching on, then the screw pillar becomes --62a-- turned and the carriages --63-- it forward-moves to the left whereby the micrometer --64-- the pistons of the mixer --50-- in interference with the elastomers the material and thus the catalyzed material moves by the end piece --51 "-- and the internal pipe --30-- through-pressed. The Mikrol0 meter --64-- is intended, in order to make possible Tasteroder feeler attitudes during the enterprise, as well as for the pre-setting of the attack between the micrometer end --64 '-- and the front cap --54-- the mixing unit. If are wished to measure can a resetable digital counter planned, in order the turns of the spindle and to make possible thus an exact announcement of the delivered quantity. Since the principal purpose of the operating device consists after Fig.6 of exerting a constant pressure on catalyzed elastomers the material whereby this pressure determined criteria regarding Uterus and device not exceed may not, the device can be also more simply implemented, as shown in Fig.8. During this execution is the mixing unit --50-- in a rack --81-- held, that on a platform --82-- is arranged. A weight --83-- lies on the end cap --54-- the mixing unit up and runs lengthwise from columns --84 and 85--, preferably on linear antifriction bearings. The column --84-- a Schraubgewinde has --84a-- and an adjustable attack --86--, which intervenes in the thread, to adjusting the adjustable mass of the weight --83--. The adjustable attack --86-- several functions, i.e. a starting and a quilting, as well as education of an edition for the weight has --83--, that on the piston of the mixing unit --50-- mount. By the center of the weight --83-- a micrometer can run (not shown), similarly as in Fig.6, for exact attitudes. Alternatively or in connection the arrangement knows an electrical coil --89-- have, those around or both of the columns --84, 85-- is wound. The columns consist of a paramagnetic material. The coil can be normally excited by the normally closed switch --87-- with the help of an energy source --88--, whereby the weight --83-- in a suitable vertical position one holds. The switch --87-- to interrupt around the circuit and the weight on the front cap can be foot-operated --54-- rest upon to leave. If the manipulation of the switch is terminated, then the circuit is again excited and progressing the weight is stopped. In the following now the method according to invention is to be described. The patient preparatory for the hysteroskopische investigation with application of normal medical functions and local Betäubung (bearing mother range). Air within the Hysteroskopgehäuses is replaced by a Hystereskopflüssigkeit, for example 32 Dextran in 70 in 10B glucose, u.zw before would bring the instrument into the cervix. This effectuation by latches of the valve --16-- and opening the valve --18--, on which the equipment is connected with a connection not shown. The Hysteroskop is then inserted into the bearing mother channel and the Hysteroskop fluid, which is to the Uterus for the following procedure at pressure (under 150 mm Hg), extends. The mechanism after Fig.8 can be used for this purpose (with 50 cm3-Spritze in place of the mixing unit --50--). The introduction of the Hysteroskop fluid creates a boundary layer at the objective lens and makes a clear and relatively unhindered observation possible of the Uterus. It is a characteristic of the invention that the Hysteroskop can be used, in order to sometimes identify that to entrance into the Eileiter, which can be found with difficulty. This reached by injecting a small quantity of 0,01% blue in a normal salt solution into the flow channel --30--. This salt solution has a lower viscosity than the HysteroskopFluid and it was found that it forms “rivers”, which flow to the interesting express pus lumen. This river identifies positively the express pus entrance. The catch point becomes now firm in the express pus entrance with the help of the pusher --19-- positioned, in order to achieve a moderate sealing strength. At this time into the mixing unit, which already contains the elastomers the material, the catalyst, e.g. tin (II) is added - to Octoat. This appropriately accomplished using gas densities a syringe, whose needle tip is through introduced approximately halfway to the mass in the mixing unit by the end piece. The piston rod of the mixing unit is then moved hinund, in order to mix contents thoroughly (whereby the point is covered with a cap). After mixing the head becomes --54-- in the expenditure position locks, by a 90°-Drehung the counterclockwise (seen of the end of the cap ago). The cap is removed and a small quantity of the catalyzed mixture is squirted on a glass plate. This forms an external sample, at which the hardening by precipitation can be supervised, whereby hiedurch at the same time any only weakly catalyzed material within the dead range at the point is delivered. The mixing unit becomes now with the end of the pipe --30-- connected, that of the case --60-- and it goes out in the owner of the arrangement after Fig.6 is arranged. The micrometer is stopped, to its head --64 '-- the cap --54-- affected. The engine of the actuation equipment after Fig.6 is excited and the flow boundary surface between the colored salt solution and the catalyzed mixture is observed, in order to obtain a free forward movement. At the same time can at the eyepiece --14-- the Hysteroskops the catalyzed mixture to be observed, those the colored fluid replaced and it can the river in the transparent tubes --30 and 31-- are observed. Any announcements of return flow of the colored salt solution in the Uterushohlraum can by strengthening the finger strength on the pusher --19-- are eliminated. If it is then observed that the boundary layer of the catalyzed mixture straight in the 2s operating channel of the Hysteroskops disappeared, can be reduced the engine speed by approximately 75, until the boundary layer in the Hysteroskop by the eyepiece --14-- to see and/or in the field of vision arrived. If this is the case, the engine is switched off and the normal pressure in the system leads to a flow movement of the material. At this time becomes, as Fig.3 shows, which positions catch point attached and/or, as Fig.3A shows. If the flow movement progresses, the fluid appears as shown in Fig.3B. The number of revolutions of the engine can be stopped then in such a way that the liquid material fills out the Eileiter fully, i.e. that it fills out the Eileiter sufficiently, so that hard becoming elastomers material on both sides of the neck (i.e. the bottleneck) of the express pus tube is present, so that it is mechanically embodied in the Eileiter after the hardening by precipitation. After approximately 2 1/2 min after completion of the mixture enters a Geilerung in the outside sample and the river by the transparent tubes --30 and 31-- is terminated. The catch point is kept firm in contact with the express pus entrance, over further 1 1/2 min, to which time the outside sample a something of fragile reading table behavior points (obviously the behavior is different like the assigned time of the sample) with different quantities of used catalyst. At this time the left section of the case becomes --60-- solved and the pipes --30 and 31-- are made independent and/or placed. The pusher --19-- in position and the internal tube is held --30-- one withdraws, until you are to be seen other end straight outside of the operating channel. Hiedurch is broken off that hardened elastomers end of the flow pipe, as is shown in Fig.3C 4s. The outside pipe is withdrawn now from the operating channel and the valve --16-- one closes. The hardened elastomer with its loop --24-- and the catch point --20--, which form now a unit, are pointed to Fig.3D. The procedure is then repeated for the other Eileiter using new pipes and a second mixing unit. After this was accomplished for the other express pus entrance, a flat X-ray plate is used, in order to examine and/or confirm the attitude of the plugs in suitable length. Fig.4 shows an alternative execution form, with which no catch point is used, but the point is formed on the spot. During this arrangement the internal pipe becomes --30-- after hardening withdrawn, whereby the elastomers the material is broken off, as is shown in Fig.4C. The internal pipe is then brought back in contact, so that the outside pipe can be withdrawn opposite this, as Fig.4D shows. If the pipes extend equivalent far, as by the eyepiece of the Hysteroskops are observed s can, both pipes are taken out and removed, whereby a formed plug stays, as it is shown in Fig.4E. If it should be desired at a later time to remove the empfängnisverhütenden part a Hysteroskop of the kind shown in Fig.1 can be used, in order to extend the Uterus, whereby a hysteroskopische liquid is used, as described, of removing as well as usual pliers or a blunt hook, which are introduced to the operating channel, in order the plugs. (The hook is used, if the plug possesses a loop). The distance takes place then similarly in principle as those, which is normally implemented with a rubber band. Since the volume of a rubber band remains constant with stretching, the diameter decreases necessarily. The same steps on with the plugs after the invention. IS due to the smaller diameter is solved the plug from the walls of the Eileiters and permits a removal with only a small Kraft.
