BI-DIRECTIONAL FIXATING/LOCKING TRANSVERTEBRAL BODY SCREW/INTERVERTEBRAL CAGE STAND-ALONE CONSTRUCTS

A bi-directional fixating transvertebral (BDFT) screw/cage apparatus is provided. The BDFT apparatus includes an intervertebral cage including a plurality of internal angled screw guides, a plurality of screw members, and a novel screw locking mechanism which consists of leaf springs which mechanically interact with BDFT screws which have ratcheted screw heads.

Interbody spinal fusion implants

The present invention discloses a spinal fusion implant that is at least partially cylindrical, made of material appropriate for human implantation and having preferably, but not necessarily, one closed end and one end capable of being closed, such that an internal chamber can be filled and hold any natural or artificial osteoconductive, osteoinductive, osteogenic, or other fusion enhancing material. The partially cylindrical implant directly participates and is incorporated in the ensuing fusion. In the preferred embodiment, the implant of the present invention relies on surface roughenings of the outer surface to enhance its stability and resist dislodgement from within the disc space between two adjacent vertebrae. The implant of the present invention incorporates at its rear end, an engagement means to facilitate insertion or extraction of the implant. The implant may be filled with, coated with, and/or composed of, fusion promoting substances. Finally, the implant of the present invention does not require rotation for its insertion and can be seated by linear advancement.

Device for the fracture of the blood vessel lining

A device for the selective fracture of the inner lining or tunica intima of a blood vessel without severing of the surrounding outer layer or tunica adventitia of the vessel is disclosed. The device comprises a combination of an anvil member having a dull blade affixed thereto which acts as one blade of a guillotine which descends upon the vessel caught between it and a hammer member of the guillotine. The hammer member is spring loaded through connection with a slider arm which extends upward toward the spring and a grip for the fingers of the user. There is provided a guide for the anvil and its blade which guide is aligned and connected with the central rod which extends between the slider arm and the spring which causes impact on the hammer member of the guillotine. The central rod acts as a core for two springs which surrounds the same. The first spring is referred to as a proximal compression spring and the second spring is referred to as distal actuator spring which is located peripherally to the proximal compression spring. The action of the first compression and the release of these two springs causes a shock to extend down the central rod or core into the slider arm and hence into the hammer portion of the guillotine. This shock action follows a first closing of the opening between the anvil and the hammer of the guillotine and is of such controlled momentum that it causes the dull blade of the anvil to fracture the inner layer of the blood vessel without severing the outer muscular layers of the blood vessel.

Stone extractor and method

Instrument and method for removing stones (calculi) from the kidneys, the bladder and other parts of the body. A stone is captured in a basket at the distal end of an elongated tubular member and broken into pieces while it is held by the basket. The stone is broken up by a hammering action provided by a reciprocating shaft which extends through the tubular member into the basket and is driven toward the stone by a spring. The stone is removed from the body by withdrawing the tubular member from the body with the pieces of the stone in the basket. Since the tip of the shaft impacts upon the stone inside the basket, the instrument is safe in that the reciprocate tip cannot strike the tissue outside the basket.

Device for generating of one-impulse shock wave

FIELD: medicine. ^ SUBSTANCE: invention concerns medical equipment and can be used in urological surgery for crushing of stones in renal ducts. The device of generating of an one-impulse mechanical shock wave contains a shock agent for high rate striking blows on an agent of generating of a shock wave. The wave is transferred by shock wave transmission media to the object intended for crushing with which the mentioned agents are in immediate or indirect contact. The shock agent is set in motion under the influence of force of expansion of the compressed gas. Gas is submitted before producing every impulse of a shock wave to an agent of accumulation, which is supplied with gas of high pressure from independent agents of storage by means of extenders of gas and food and hermetic sealing agents. Gas is released by manual actuating of control facilities. ^ EFFECT: device generating a shock wave of the big amplitude transferred through a skin or through natural ways by means of an endoscope is as a result framed, allowing to carry out controlled crushing of an urinary stone for its fragmentation on a small number of pieces in the size necessary and sufficient for their extraction manually by means of forcepses through endoscope, entered for a fragmentation of stones, for a direct vision behind them, their capture and extraction. ^ 10 cl, 2 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 352 274 (13) C2 (51) МПК A61B 17/22 A61B 17/16 (2006.01) (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ, ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21), (22) Заявка: 2005128552/14, 30.01.2004 (24) Дата начала отсчета срока действия патента: 30.01.2004 (73) Патентообладатель(и): ЛМА Уролоджи Лтд.
