Abstract
A suturing instrument for use in arthroscopic surgery includes a hollow needle for penetrating tissue to be sutured within the body while the tissue is clamped between relatively movable jaws, and a suture feed mechanism for feeding suture material through the hollow needle such that the jaws can be opened and the suturing instrument withdrawn from the body pulling the free end segment of the suture material with the instrument. A knot can be tied in the suture material externally of the body and the knot moved back into the body at a position adjacent the tissue.
