    • An instrument for locating the cutting plane on the head of a long bone in a surgical procedure, wherein the head of the bone is replaced with a joint prosthesis component, includes an axial reference shaft which can be arranged parallel to the axis of the bone and a cutting guide which can be moved relative to the axial reference shaft. The cutting guide has a reference block for location against the bone relative to the edge of the bone at one side and at least one arm which is shaped so that it can extend from the cutting guide over the face of the head. The arm can be located positively with respect to features on the head so that the location of the reference block along the axis of the bone can be set with reference to features on the head of the bone which are contacted by means of the arm.
    • 一种用于在外科手术过程中将切割平面定位在长骨头上的仪器,其中骨头被关节假体部件替换,包括可以平行于骨轴线布置的轴向参考轴, 可以相对于轴向基准轴移动的切割引导件。 切割引导件具有用于在一侧相对于骨的边缘抵靠骨头定位的参考块,并且至少一个臂被成形为使得其可以从头部的表面上的切割引导件延伸。 臂可以相对于头部上的特征正向定位,使得参考块沿着骨的轴线的位置可以参考通过臂接触的骨头上的特征来设定。
