Abstract

A surgical clamp includes a support frame clamp member, a retraction shaft clamp member and a handle linked to the support frame clamp member and the retraction shaft clamp member for moving the clamp members between loosened and tightened positions. The handle includes a cam, and the handle/cam is unitarily formed by metal injection molding. The handle includes relatively uniform thickness throughout to better accept the shrinkage induced by the metal injection molding process. The base used for a bottom position of the cam is adjustable and spring loaded, to better support a wider range of manufacturing tolerances on the cam as well as the other components of the clamp without over stressing the metal injection molded handle during use. The handle includes a gripping portion with a planar portion inducing alignment of the clamping force as desired for best operation of the clamp.
