First Claim
Patent Images
1. A suturing instrument comprisingan elongate member having a distal end and a proximal end;
- first and second jaws disposed at said distal end of said elongate member to be movable relative to each other, said first jaw having an opening therein and said second jaw including means for penetrating tissue to be sutured and an opening therein;
means operable at said proximal end of said elongate member to move said first and second jaws from an open position spaced from each other to a closed position adjacent each other with said openings therein aligned; and
means for feeding suture material through said openings in said first and second jaws whereby suture material can be passed through tissue to be sutured after penetration by said second jaw with said first and second jaws in said closed position.

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for feeding suture material through the hollow needle such that the jaws can be opened and the suturing instrument withdrawn from the body pulling the free end segment of the suture material with the instrument.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.

6. A suturing instrument comprising
elongate tubular means having a proximal end and a distal end; -
jaw means disposed at said distal end of said tubular means for penetrating tissue to be sutured and forming a passage for passing suture material through said jaw means and the tissue to be sutured; means operable at said proximal end of said tubular means for moving said jaw means to penetrate the tissue to be sutured; and means for feeding suture material from said tubular means through said passage and the tissue to be sutured. - View Dependent Claims (7, 8)
