摘要： An intercondylar notch cutter using a plunge milling bit and bit guide which engages parallel tracks in a trial prosthesis. The intercondylar notch cutter comprises a cutting bit and a guide sleeve. The cutting bit can be thrust into the femur and then translated through the femur cutting a notch without removing the trial prosthesis. The bit is supported by a guide or housing with a guide platform which extends medially and laterally from the guide. Two condyle articulating surfaces on the platform slidingly engage a condyle surface on a trial prosthesis. Along the condyle surfaces on the trial prosthesis are two parallel grooves. Posts on the notch cutter are slidingly received within the grooves. A surgeon first places the trial implant on the femur without cutting an intercondylar notch. The surgeon can proceed immediately to cut an intercondyle notch without removing the femoral trial prosthesis.
摘要翻译：一种使用插入铣头和钻头引导件的髁间切割刀具，其与试验假体中的平行轨道接合。髁间切割器包括切割钻头和引导套筒。切削刀头可以推入股骨，然后通过股骨翻转切口而不移除试验假体。该钻头由具有引导平台的引导件或外壳支撑，导向平台从引导件中间和横向延伸。平台上的两个髁关节表面滑动地接合在假体上的髁表面。沿着试验假体的髁表面是两个平行的凹槽。切口刀具上的刀片滑动地容纳在凹槽内。外科医生首先将试验植入物置于股骨上，而不切割髁间隙。外科医生可以立即进行切割髁间隙，而不需要移除股骨假体。

摘要： A surgical jig for orienting a femoral component of a prosthetic knee prosthesis angularly with respect to the axis of the patient's femur which jig utilizes a single drill plate or guide for condylar pins, but permits variation in the placement of those pins. The jig comprises a distal plate which is placed against the distal end of the femur. The distal plate has two condyle fingers for grasping the posterior side of the femoral condyles. Gage means are provided to measure the size of the distal end of the femur. A rotatable drill guide permits the surgeon to adjust the placement of two drill bores for receiving condyle pins on a femoral component of a knee prosthesis.
摘要翻译：一种手术夹具，用于使假肢膝关节假体的股骨部件相对于患者股骨的轴线成角度地定向，该夹具利用单个钻孔板或引导件用于髁销，但允许这些销的位置变化。夹具包括靠近股骨远端的远端板。远侧板具有两个髁指，用于抓住股骨髁的后侧。提供测量装置以测量股骨远端的尺寸。可旋转的钻子引导件允许外科医生调整两个钻孔的位置，用于接收膝关节假体的股骨部件上的髁突销。

摘要： A posterior stabilized knee prosthesis with removable pin in the femoral component. The removable pin has a tapered split ring lock which prevents the pin from backing out. A split ring is provided on the pin which rides in a groove on the pin. When the pin is properly seated, the split ring engages a corresponding groove within the femoral prosthesis, locking the pin in place. Chamfers are provided on both the front and back of the split ring so that the split ring will compress as the pin is being screwed into the femoral component and also so that the pin can be removed if necessary.
摘要翻译：在股骨组件中具有可移除销的后稳定的膝关节假体。可拆卸销具有锥形开口环锁定，防止销退出。销上设置有一个开环，该开环环在销上的槽中。当销正确就位时，开口环与股骨假体内的相应凹槽接合，将销钉锁定就位。在开口环的前部和后部设置有倒角，以便当销被拧入股骨部件时，开口环将压缩，并且如果需要，销可被移除。
