(EN) Guide assembly for guiding cuts to a femur and tibia during a knee arthroplasty
(ZH) 用于在膝关节成形期间引导股骨和胫骨的切削的引导组件
Abrégé
(EN)
An assembly for guiding resection of a femur and tibia of a knee joint in preparation for installing a femoral and tibial knee components. For example, the assembly can include tibial and femoral IM rods to which are connected through a torque bolt that allows controlled adjustment of the distraction of the tibia and femur during cut positioning in a range of flexion angles. Also, the assembly is usable with relatively small, noninvasive approaches to the knee joint by way of relatively narrow, low profile components that attach to tibial and femoral IM rods. Further, the assembly includes several quick-release components to allow fast assembly and disassembly in a surgical setting. Each of these aspects, along with the ability of the assembly to accurately guide initial reference cuts to the tibia and femur, promotes an improved outcome for the patient.

(ZH)

一种用于引导膝关节的股骨和胫骨的切除以便为安装股骨和胫骨膝关节部件作准备的组件。例如,所述组件可以包括胫骨IM杆和股骨IM杆,所述胫骨IM杆和股骨IM杆通过扭矩螺栓连接,所述扭矩螺栓允许在弯曲角度范围内进行切削定位期间受控地调节胫骨和股骨的分开。此外,通过安装至胫骨IM杆和股骨IM杆的相对狭窄的、低剖面的部件,组件可以相对小地、非侵入性地接近膝关节。此外,组件包括若干快速拆卸部件,以允许在手术设置过程中快速地装配以及拆卸。这些方面中的每一方面连同组件精确引导胫骨和股骨初始参考切削的能力,促进了患者手术效果的改善。
