Abstract
Abstract The surgical instrument of the invention consists of a pair of arms hinged together at an intermediate point for relative pivoting movement. The arms are provided with obliquely oriented handles at one end thereof. The opposite ends of the arms support removable posts having means for removably securing a plurality of different retractor or compressor heads thereto. The posts are pivotably connected to the arms to allow the posts to achieve a variety of orientations relative to the arms. A variety of retractor and compressor heads and different shaped posts are provided to allow the instrument to be used in a wide variety of surgical procedures. Separate serrated locking mechanisms are provided to lock the arms in either a retraction or compression position. In one embodiment the posts are secured to one another such that they undergo parallel retraction/compression.
