  • Patent number: 10568644
    Abstract: An orthopaedic surgical instrument assembly includes a system handle configured to clamp a broach and femoral stem trial assembly. The system handle includes a clamp lever and a release lever both pivotally coupled to the system handle, and a leaf spring connecting the clamp lever and the release lever. When the release lever is moved from an unclamped position to a clamped position, the leaf spring is put in tension, and the clamp lever engages a flange of the broach, securing the broach to the system handle. Methods of assembling the system handle are described and claimed.
