摘要：An instrument assembly for use in orthopaedic surgery comprises a reamer orother cutting component which is to be positioned within a body cavity to engage a bone,having at least one bar portion extending across it. A manipulator has at least one claspfor engaging the bar portion so as to fasten the cutting component to the manipulator,

the clasp comprising a hook and a keeper pin. The hook can be displaced relative to thekeeper pin between an open position in which the keeper pin is retracted relative to thehook so that the hook is open at one side to allow the bar portion to be slid between thehook and the keeper pin, and a closed position in which the keeper pin closes the hooksufficiently to prevent the bar portion from being removed from under the hook. At leastone of the contacting surfaces of the bar portion and the hook which contact oneanother when the bar portion is inserted between the hook and the keeper pin, or thesurface of the bar portion which contacts the keeper pin, provides a ramp so that slidingthe bar portion between the hook and the keeper pin causes the hook to be displacedrelative to the keeper pin, towards the open position. The hook is biassed towards theclosed position.
