    • A surgical instrument is disclosed that facilitates the implantation of one of a number of differently sized or differently configured hip stem prostheses into a proximal end of a femur while also providing a surgeon with a substantial amount of rotational control over the prosthesis during the implantation. A suitable hip stem prosthesis is selected from a family of hip stem prostheses of varying sizes and dimensions. The surgical instrument attaches to the selected hip stem prosthesis via first and second spaced engagement portions such that the instrument is operable to exert rotational control over the selected hip stem prosthesis. The first engagement portion is an impaction portion configured to engage a corresponding impaction feature on a proximal body portion of the hip stem prosthesis. The second engagement portion is an adjustable clamping portion configured to clampingly receive the neck of the hip stem prosthesis, regardless of the prosthesis size.
    • 公开了一种手术器械,其便于将多个不同尺寸或不同构造的髋关节假体中的一个植入股骨的近端,同时还为外科医生在植入期间对假体进行大量的旋转控制。 适合的髋关节假体选自不同大小和尺寸的髋关节假体系列。 手术器械通过第一和第二间隔的接合部分附接到所选择的髋部假体,使得该器械可操作以对所选择的髋部假体进行旋转控制。 所述第一接合部分是被构造成与所述髋关节假体的近端主体部分上的相应冲击特征相接合的冲击部分。 第二接合部分是可调整的夹紧部分,其构造成夹紧地接收髋部假体的颈部,而与假体尺寸无关。
