Surgical clamp and drill-guiding instrument

A surgical clamping and drill-guiding instrument for gripping a bone exposed during surgery and providing an accurate drill guide comprising:

• an L-shaped member having an elongated keyed post and a leg extending from the post, the leg having a screw receiving portion for positioning on one side of the bone to be gripped;
• an elongated clamping screw having a longitudinal opening means therethrough for receiving a removable drill guide of a chosen size for guiding a drill of said chosen size for drilling into the bone, and a clamping member rotatably mounted about said opening means at the engagement end of said screw facing the bone, said clamping screw being engageably disposed in said screw receiving portion;
• and
• a central body portion with an opening for receipt of said post and being displaceable along said post;
• an arm extending from said body portion generally parallel to said leg, said arm including fingers for engaging the outer side of the bone and having an opening between said fingers for cooperating with the opening means in said screw and locking means for locking the body portion at a preselected position on said post;
• said post, when received within and being in movable keyed engagement with said body portion, provides an alignment means which facilitates the cooperation of the opening means in said screw with the opening between said fingers;
• said screw and clamping member displaceable through said screw receiving portion on said leg towards the bone so as to fixedly locate said drill guide with respect to the bone disposed between said clamping member and said fingers on the arm for providing a vise-like grip about the bone.
