Vacuum biopsy device

The biopsy device consists of a hand piece, in which a hollow biopsy needle is inserted, wherein a part of the portion of the biopsy needle projecting beyond the hand piece with its sample removal chamber can be inserted into the tissue being investigated and the tissue is sucked into the sample removal chamber by vacuum and then separated by means of a sample separating mechanism and afterwards removed. The vacuum generating device can be used as necessary to generate an excess pressure by opening a ventilation opening; furthermore, the vacuum pressure-generating device (5) as well as other control and supply devices and the electrical actuators are integrated in the housing of the hand piece (1) and the connection element (4) between the biopsy needle (3) and the vacuum pressure-- generating device (5) is arranged directly on the housing.

The device allows a single-hand operation. The device combines the advantages of the high- -speed biopsy guns with the advantages of vacuum biopsy and furnishes the pathologist better specimens for analysis.

Flexible coating for magnetic resonance imaging compatible invasive devices

Invasive devices, such as laser fiber guides and biopsy needles, constructed of a material which exhibits little or no magnetic susceptibility, have a flexible polymer coating for retaining pieces of the device in the event of a fracture of the invasive device. The polymer coating also allows removal of the pieces of a fractured invasive device from the body of a subject without requiring surgery. The surgical instruments can be used inside a magnetic field during magnetic resonance (MR) imaging, thereby allowing interactive internal images to be produced and displayed to a surgeon during surgery. Since the invasive devices exhibit low susceptibility, they do not distort a created MR image.

Magnetic resonance guided ultrasound therapy system with inclined track to move transducers in a small vertical space

A magnetic resonance (MR) surgery system facilitates surgery with a focussed ultrasound transducer that selectively destroys tissue in a region within a subject. The focussed energy transducer dissipates energy at a focal point within the region of tissue to be destroyed. A non-magnetic positioning device having a vertical dimension small enough to fit easily within the bore of an MR magnet moves an energy transducer in a limited vertical space. The positioning device employs a plurality of hydraulic positioners and an inclined plane to position the ultrasound focal point under the control of an operator. An MR imaging system employing a temperature sensitive pulse sequence creates an image of the tissue and the region being heated to allow the operator to adjust the position of the ultrasonic transducer so as to direct ultrasonic energy to the appropriate location.

Mechanical positioner for magnetic resonance guided ultrasound therapy

A positioner for a magnetic resonance (MR) surgery system which positions a focal point of an ultrasound transducer to selectively destroys tissue in a region within a patient. The positioning means moves an ultrasound transducer under the control of an operator. Mechanical threaded shafts and slides act as screw drives causing several connected slides to move the ultrasound transducer in three dimensions. Expanding shafts are connected between a fixed point on a housing and the actuating point of the threaded shafts. Two of the expanding shafts employ universal joints allowing the shafts to rotate as they follow the slides. The third expanding shaft need only expand but the relative angle between its attachment points does not change, thereby eliminating the need for universal joints. An MR imaging system employing a temperature sensitive pulse sequence, creates an image of the tissue and the region being heated to allow the operator to adjust the position of the ultrasonic transducer so as to direct ultrasonic energy to the appropriate location.

Carbon fiber magnetic resonance compatible instruments

Instruments are constructed of a carbon fiber material optionally doped with a doping agent such as iron oxide, the instrument having a magnetic susceptibility being adjusted to a portion of a subject being imaged. Therefore there is little effect upon the lines of magnetic flux and the magnetic field homogeneity, reducing distortion in an MR image. These carbon fiber instruments exhibit virtually no magnetic torsional forces when inserted into a magnetic field. This is important, for example when the instrument is a scalpel. Doped carbon fiber has minimal affect on radiofrequency fields. The instruments do not affect the homogeneity of an applied homogeneous magnetic field or an applied radiofrequency field. Doped carbon fiber exhibits a rigidity large enough to allow construction of high strength instruments such as biopsy needles. It also has the ability to retain a sharp edge, allowing construction of scalpels and cutting instruments. Doped carbon fiber surgical instruments may be used inside a magnetic field during magnetic resonance imaging, thereby allowing interactive internal images to be produced and displayed to a surgeon during surgery. A method is also disclosed for imaging a control material and then the instrument to determine the type and amount of doping agent required.

Remote actuation of trajectory guide

A surgical method and apparatus for accurately aligning the trajectory of, guiding of, and introducing or withdrawal of an instrument is disclosed. The apparatus includes a base which has a movable member movably attached to the base. The movable member has a passage therein which forms a portion of the trajectory path. A positioning stem further includes a first locator and a second locator. The first and second locators are associated with two different portions of the positioning stem so that they are essentially two points on a line. The first and second locators are also locatable by a scanning or imaging system. The positioning stem is removably attached to said movable member and used to position the movable member. Moving the movable member also moves the passage therein to different trajectories. Once the passage within the movable member more or less is aligned with a target within the body, a locking member locks the movable member into a fixed position. The movable member can be moved to different trajectories using a first hydraulic system. A second hydraulic system can be used to introduce or withdraw an instrument to or from the patient. A mechanical advancement tool can be substituted for the second hydraulic system. The surgical instrument may also be provided with a remote portion for controlling the instrument from a remote location. The instrument can also be computer controlled.

Mri biopsy device

一种定位机构或者夹具，其在开放和闭合磁共振成像(MRI)机中的趋向活组织检查过程中与乳房线圈结合用于对乳房施压和导引针芯活组织检查仪器。该定位夹具包括一个可三维Cartesian定位的导向件，用于将MRI相容活组织检查装置，特别是套管支撑和定向于可疑组织或病变的活组织检查位点。限深器增加了插入精确性，防止了套管过插或者无意的回缩。套管接收MRI相容活组织检查仪器的探头，并可包括各种部件以增强其可成像性，增强真空及压力辅助，等等。

Implanted system for bone stabilisation

FIELD: medicine. SUBSTANCE: invention refers to medicine. An implanted system for bone stabilisation provided with a component accommodating an elongated rod that has at least one segment wherein it can be attached to an attachment section, e.g. to a pedicular screw or clamp. The elongated rod is made of plastic transparent to X-rays, and is rigidly attached to an auxiliary element coupling the elongated rod to the above attachment section, on at least the above section. The above auxiliary element is structured from the outside to be attached to the attachment section and to conjunct the fit surface structure elements. The surface structure is formed by hollows and projections. EFFECT: invention provides X-ray transparency and prevents forming artefacts. 13 cl, 19 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 514 886 C2 (51) МПК A61B 17/70 (2006.01) A61B 17/68 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ 2011128263/14, 08.12.2009 (24) Дата начала отсчета срока действия патента: 08.12.2009 Приоритет(ы): (30) Конвенционный приоритет: (72) Автор(ы): ФИХТЕР Майнрад (CH), МАГЕРЛЬ Фридрих (CH), ВИЛИНГ Роналд (CH) 19.12.2008 EP 08405310.7 (43) Дата публикации заявки: 27.01.2013 Бюл. № 3 R U (73) Патентообладатель(и): СЕПИТЕК ФАУНДЕЙШН (LI) (45) Опубликовано: 10.05.2014 Бюл. № 13 (85) Дата начала рассмотрения заявки PCT на национальной фазе: 19.07.2011 C 2 C 2 662081A1, 15.05.1979.
