摘要： A trial neck for hip surgery and a method of attaching a trial neck to a femoral canal implement. The trial neck includes a body portion including a bore for receiving a proximal end of a femoral canal implement. The trial neck also includes an elongate neck extending from the body portion. The trial neck further includes a locking mechanism comprising a lever. The lever has a first end. The lever also has a second end. The lever further has an engagement surface. The second end of the lever is actuable to urge the engagement surface against the proximal end of the femoral canal implement to secure the proximal end of the femoral canal implement within the bore.

摘要： A trial neck for hip surgery and a method of attaching a trial neck to a femoral canal preparation instrument. The trial neck includes a body portion including a bore for receiving a proximal end of a femoral canal preparation instrument. The trial neck also includes an elongate neck extending from the body portion. The trial neck further includes a locking mechanism comprising a lever. The lever has a first end integral with the body portion. The lever also has a second end. The lever further has an engagement surface located intermediate the first end and the second end. The second end of the lever is actuable to urge the engagement surface against the proximal end of the femoral canal preparation instrument to secure the proximal end of the femoral canal preparation instrument within the bore.

摘要： A trial neck for hip surgery and a method of attaching a trial neck to a bone canal preparation instrument. The trial neck includes a body portion having a bore for receiving a proximal end of the bone canal preparation instrument. The trial neck also includes an elongate neck part comprising a pair of arms extending from the body portion. The trial neck further includes a clamping mechanism comprising a live spring formed by the body portion and said pair of arms of the elongate neck part and an actuator, for moving the clamping mechanism between a clamping configuration and a non-clamping configuration. In the clamping configuration, the pair of arms of the elongate neck part are pinched together to cause an inner wall of the bore to urge against the bone canal preparation instrument to retain the proximal end of the bone canal preparation instrument within the bore.
