Abstract
A surgical instrument for creating a tissue canal in which to seat a sleeve has a shaft tube with a knife blade at its distal end to form an incision and an insert to transform the incision into the tissue canal. The knife blade is formed as an axially projecting portion of the distal edge of the shaft tube and has a ground edge for cutting in the circumferential direction of the shaft tube. The insert is slidable mounted in the shaft tube and has a distal blunt end located adjacent the distal end of the shaft tube.
