Abstract
A surgical method and apparatus and cannulated scalpel for use therein are provided. In particular, the cannulated scalpel is used during surgical procedures to make an incision through intervening tissue about a guide pin having an end for engaging a target tissue, such as bone. The scalpel includes a hollow, elongated shaft adapted to slide over the guide pin and a head mounted at one end of the shaft. The head has at least one leading cutting edge that is adapted to cut along a plane through the intervening tissue as the shaft slides over the guide pin toward the target tissue engaging end of the guide pin. The scalpel can then be removed from the incision along the plane, preferably with the aid of a trailing guide edge. Following removal of the scalpel, a driving tool, such as a power surgical drill, can be introduced to drive a cannulated fastener along the guide pin and through the incision to embed the fastener in the target tissue and provide fixation of the target tissue.
