摘要： Surgical instrumentation and a method for cutting bones on one or both sides of a joint such as the knee joint to allow the application of a joint prosthesis. A rod is inserted into the medullary canal of the bone to be cut. The rod is secured within the medullary canal and a router guide is mounted on the rod for rotation thereabout while being restrained against movement axially of the rod. A router or side cutting drill is inserted through the router guide into contact with the rod and actuated to rotate about its own axis. The router guide and the router are then caused to rotate about the rod to thereby cut the bone to produce a substantially planar surface thereon suitable to bear against a joint prosthesis.

摘要： An instrument for determining the variation in tension of a ligament graft extending between first and second proposed fixation sites positioned on first and second articulated bones, respectively, comprises a yoke which carries a device for securing the yoke to one of the first and second bones. A yoke plate is rotatably carried by the yoke. A main housing is adapted for connection to the yoke plate. A sled is slidably carried by the main housing. The sled is adapted for connection to the ligament graft. A mechanism is provided for adjusting the position of the sled relative to the housing so as to place a desired degree of tension on the ligament graft. A transducer is associated with the mechanism for adjusting for determining changes in tension, if any, from the desired degree of tension as the first and second bones are moved relative to one another.

摘要： A shielded magnetic assembly for use in a magnetic hearing aid is described. The shielded assembly uses a disc-shaped magnet with a high permeability, low coercivity material placed on the face of the magnet away from the air gap. Preferably, the shielding material also covers portions of the edge of the magnet to form a cap. The shielding focuses the magnet's energy into the air gap to improve coupling and reduce interference from external magnetic fields.

摘要： An apparatus for treating fractures of the femur including a screw and an intramedullary rod. The screw has a threaded portion and a smooth portion. The rod has a head, stem and a longitudinal bore. There is at least one pair of coaxial holes through the stem, transverse to the longitudinal axis of the rod, for receiving first anchoring means, such as a nail, screw or bolt, to secure the rod within the marrow canal of the femur. There are at least a proximal pair of coaxial holes and a distal pair of coaxial holes in the head of the rod in an angled direction toward the femoral head relative to the longitudinal axis of the rod. The distal pair of head holes are adapted to slidingly receive the screw to permit the threaded portion of the screw, in use, to engage the femoral head and to allow sliding compression of a femoral neck or intertrochanteric fracture. An optional second anchoring means which will also allow sliding compression and an optional set screw are also provided to adapt the fracture device to a variety of applications.

摘要： A prosthetic ligament assembly includes a nonaugmented prosthetic ligament for permanently replacing a natural ligament spanning first and second body members, such as the femur and tibia, and a bone screw adapted for tensioning the prosthetic ligament during implantation. The prosthetic ligament includes a load bearing member intertwined into a plain braid from a plurality of biocompatible, high strength, ultra high molecular weight polyethylene yarns. Each yarn includes at least fifty fibers and has a tensile strength greater than or equal to about 100,000 psi. The load bearing member has a gage section and a loop at each end thereof for anchoring the load bearing member to the body members. The load bearing member is preloaded to remove slack therefrom. The load bearing member may be used alone or may be formed into a hollow braid having a core disposed within the hollow portion of the braid to permit radiographic visualization of the prosthetic ligament. A sheath may be friction fit or molded onto the exterior of the gage section. The assembly also includes one or two bone screws for complimentary engagement with the loops of the load bearing member. The bone screws have a tapered section extending beneath the head of the screw to the shank for tensioning the prosthetic ligament during implantation.
摘要翻译：假肢韧带组件包括用于永久地替换跨越第一和第二身体构件（例如股骨和胫骨）的天然韧带的修饰韧带，以及适于在植入期间张紧假体韧带的骨螺钉。假体韧带包括从多个生物相容的高强度超高分子量聚乙烯纱线缠绕成平纹编织物的承载构件。每个纱线包括至少五十根纤维，并且具有大于或等于约100,000psi的拉伸强度。承载构件在其每个端部具有一定量部分和一个环，用于将承载构件锚固到主体构件上。承载构件被预加载以从其中移除松弛。承载构件可以单独使用或者可以形成为具有设置在编织物的中空部分内的芯的中空编织物，以允许假体韧带的放射线显影。护套可以摩擦配合或模制到计量部分的外部。组件还包括一个或两个骨螺钉，用于与承载构件的环互补接合。骨螺钉具有在螺钉头部下方延伸到柄部的锥形部分，用于在植入期间张紧假体韧带。

摘要： A noise elimination circuit, especially for a hearing aid, which removes all sound below a predetermined level and transmits a compressed sound range for all sounds above a predetermined level. The circuit uses a field effect transistor as a voltage variable resistor to transmit a signal when the sound signal is being compressed or is over a predetermined level and block the signal when the sound signal is not being compressed or is below the predetermined level. The field effect transistor drain to source resistance is varied by transmitting a signal indicative of the compression or signal level to the gate of the transistor, such that the gate voltage is higher than the source voltage when signal transfer is desired and the gate voltage is less than the source voltage when no signal transfer is desired. A switch is provided to defeat the noise elimination circuitry.

摘要： An apparatus for repairing torn animal body tissue in a single procedure features a suture, anchor attached at one end of the suture to prevent the suture from being pulled through the tissue, and clenching device adapted to grip the suture on the opposite side of the tissue from where the anchor device is disposed so that the torn tissue may be held together by cooperating between the anchor device and the clenching device within the body, all of which are formed of a biodegradable material so that they will all be absorbed into the body over time thereby eliminating the need for another surgical procedure to remove them from the body. The installer is used to install the clenching device with one hand so that the other is free to pull on the suture.

摘要： A nonaugmented prosthetic ligament for permanently replacing a natural ligament spanning first and second body members, such as the femur and tibia includes a load bearing member formed from a plurality of biocompatible polyolefin fibers positioned at angles of from 0.degree. to 55.degree. relative to the longitudinal axis of the load bearing member. Each fiber is less than 100 microns in diameter and has a tensile strength greater than or equal to about 50,000 psi. The load bearing member may be used alone or may be formed into a hollow braid having a core disposed within the hollow portion of the braid to provide shape for the load bearing member. A sheath may be friction fit or molded onto the exterior of the load bearing member to prevent abrasion of the fibers.
