    摘要： A monomer dispenser and vial breaker (10) includes a base portion (12) and a cap portion (14) which is attachable to the base portion (12). The base portion (12) is substantially cylindrical, has an inner seat (16) for supporting the shoulder (2) of an ampoule (1), a knurled outer gripping surface (18), an exteriorally threaded portion (20), and an open end (22) with a first locking structure (24). The cap portion (14) is substantially cylindrical, has a first open (26) end with interior threads (28) and a second locking structure (30), a second open end (32), with a strainer and a vial breaking structure (34) located between the first (26) and second (32) open ends. The cap portion (14) is also provided with a knurled outer gripping surface (36). The monomer dispenser and vial breaker (10) operate as follows: an ampoule (1) is inserted into the base (12) so that the shoulder (2) of the ampoule (1) rests on the inner seat (16), the cap (14) is pushed onto the base (12) so that locking structures (24,30) engage, and the base (12) and/or the cap (14) are twisted relative to each other so that the threaded portions (20,28) engage. As the cap (14) and base (12) are threaded together, the vial breaking structure (56) breaks the bottom of the ampoule (1). The assembled device (10) is then inverted to dispense the monomer through the second open end (32) of the cap (14). After the dispenser (10) is assembled and the monomer is dispensed, the locking structures (24,30) prevent the device (10) from being disassembled.

    摘要： A slotted patella resection guide (100) and stylus (400) used in the preparation of the human patella to accept a patella prosthesis in total knee arthroplasty. The guide includes jaw members (120, 121) for gripping bone, the jaw members including a plurality of calibrated and marked steps (slots 101-106) located at a different fixed predetermined height above the desired resection level. Each slot accepts the stylus which may be at least temporarily secured therein. After determining the amount of bone to resect, the stylus is temporarily secured in the appropriate slot (marked as being calibrated to yield the amount of resection desired); and the guide (110, 111) is then clamped onto the patella at the location indicated by the guide/stylus combination, with the stylus resting on the patella in the area where its thickness was measured to establish the depth of cut. After the guide is clamped in position, a sagittal saw is inserted therein to actually perform the resection. During resection, the stylus (400) may be removed from the guide to enhance visibility. The jaws of the guide include a saw capture slot (201a, 201b) which defines the plane of resection and accepts the saw blade to provide greater control of the cut during the operation. A saw blade insertion guide (150, 151) is also integrated into the resection guide to ease the process of inserting the blade into the capture slot and enhance safety characteristics of the instrument.

    摘要： An apparatus for use in total knee arthroplasty includes a tibia engaging plate 12 which is coupled to an upstanding rack member 14, a drill bushing bracket 16 coupled to the rack member by a lockable pinion member 18, and a femoral positioning jig 20 which is rotatably coupled to the drill bushing bracket. The drill bushing bracket 16 has a pair of spaced apart drill bushings 33,35 which are dimensionally located to correspond in position to medial and lateral condyles of the femur. The centers of the drill bushings lie in a plane which is parallel to the plane in which the tibia engaging plate lies. The femoral positioning jig 20 is provided with a pair of posterior skids 36,38, one for the lateral posterior condyle and one for the medial posterior condyle, a pair of holes 40,42 for attaching the jig to the resected distal femur with spikes, and a pair of holes 44,46 for receiving the two drill bushings. Two different femoral positioning jigs are provided, one for the right knee and one for the left knee. In both jigs, the hole 44 for receiving the medial drill bushing is circular and the hole 46 for receiving the lateral drill bushing is oblong or kidney shaped. This allows the positioning jig (and the femur) to rotate about the axis of the medial drill bushing. The positioning jigs are also each provided with angular indicia 33,35 adjacent the lateral oblong hole and the drill bushing bracket is provided with left and right indicia indicating the axial center of each drill bushing.
