Surgical suture instrument with remotely controllable suture material advancement
First Claim
Patent Images
1. A surgical suture device, comprising:
- a cylindrical tubular member defining a cavity extending from a distal end of the tubular member toward a proximal end of the tubular member;
a forcep assembly comprising at least two opposed jaw members, at least one of said jaw members being selectively displaceable with respect to said tubular member, each of said jaw members defining a lumen in fluid communication with said tubular member cavity;
means for selectively displacing said at least one displaceable jaw member; and
means for advancing suture material through said opposed jaw members so as to extend within said tubular member cavity following passage through said jaw members.

Abstract
The invention relates to surgical instruments and methods for effecting suturing of tissue that can be controlled from a position remote from the suture site. The invention provides for the continuous feed of suture material through opposed forcep jaw members between which the tissue segments are interposed to expedite the suturing process and enable suturing to be accomplished at remote internal sites of the body incident to various endoscopic procedures.

46. A method for suturing tissue at a surgical site, comprising the steps of:
-
positioning a suturing instrument adjacent the tissue to be sutured, the suturing instrument having at least two opposed forcep jaw members, at least one of the jaw members being displaceable relative to an instrument body and being selectively operable to move between a forcep open position and a forcep closed position, each of the opposed jaw members defining a lumen extending therethrough; interposing the tissue to be sutured between the opposed jaw members and urging the displaceable jaw member toward its opposed jaw member to the closed position such that at least one of the jaw members penetrates the tissue to be sutured; advancing suture material through the opposed jaw members so as to extend through the tissue to be sutured; urging opposed jaw members of said forceps to said open position; tying a knot in the suture material; and
advancing the suture knot toward the tissue to be sutured. - View Dependent Claims (47, 48, 49, 50, 52)

- 53. A device for advancing a knot formed in suture material toward tissue to be sutured, the device comprising an elongated member and a detachable end cap having means for receiving suture material, said elongated member having a knot-receiving recess formed at one end thereof and a longitudinally-extending slot which extends medially from an outer surface of the elongated member.
