Abstract
Abstract A surgical instrument, guide and method capable of being used for closure of peritoneum fascia, occlusion of bleeding vessels such as inferior epigastric, and for all uses related to accurately passing suture material through a guide into tissue with the tip of the surgical instrument in a standard suture/needle driving position with a sharp tip that opens and closes with the surgeon grasping suture material with the sharp tip and inserting the tip/suture through tissue until the tip is seen through the peritoneum by direct vision, wherein the suture is released by opening and withdrawing the tip from the guide, and recovered by using the guide to redirect the tip and puncturing the tissue opposite the first point of insertion wherein the tip grasps the suture and pulls the suture through the guide, and outside the wound providing for rapid closure of the surgical incision, and wherein a guide insertable within the wound to be closed guides the surgical instrument at a predetermined angle from the longitudinal axis of the guide.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
167 words
A device for accurately guiding and positioning a surgical instrument bearing suture material to a predetermined area within the body for closing an open wound, comprising: a guide means having a longitudinal axis and distal and proximal ends, and further having a depth-limiting extending lip near said distal end of said guide means and being generally perpendicular to said longitudinal axis, wherein said proximal end is for insertion into the wound to a depth limited and determined by said extending lip, said guide means defining therein at least one generally linear passageway therethrough at a first diverging angle less than 90° from said longitudinal axis, and providing for exit holes above and below said lip, wherein said proximal end of said guide is tapered and positionable within said wound with the lip portion above the wound to be closed and the surgical instrument carrying suture material passed through said passageway at said angle to the predetermined area within the body to assist in closing the open wound.
Claim 2
Independent Claim
167 words
A device for accurately guiding and positioning a surgical instrument bearing suture material to a predetermined area within the body for closing an open wound, comprising: a guide means having a longitudinal axis and distal and proximal ends, and further having a depth-limiting extending lip near said distal end of said guide means and being generally perpendicular to said longitudinal axis, wherein said proximal end is for insertion into the wound to a depth limited and determined by said extending lip, said guide means defining therein at least one generally linear passageway therethrough at a first diverging angle less than 90° from said longitudinal axis, and providing for exit holes above and below said lip, wherein said proximal end of said guide is tapered and positionable within said wound with the lip portion above the wound to be closed and the surgical instrument carrying suture material passed through said passageway at said angle to the predetermined area within the body to assist in closing the open wound.
Claim 3
Dependent Claim
90 words
The device of claim 1 further comprising a second passageway through said guide means forming a second angle less than 90° from said longitudinal axis, and positioned appositely adjacent said first passageway, and further having second exit holes above and below said lip, wherein the suture material can be left at the predetermined point within the body and the surgical tool and be inserted into one of said second exit holes above said lip portion through said second passageway to retrieve the suture material from the area within the body.
Claim 4
Dependent Claim
58 words
A device of claim 2 comprising an extending finger adjacent to said tapered end and generally symmetrical about said longitudinal axis extending a length sufficient to be accurately viewed and identified to provide a reference point while viewing any suturing procedure, and wherein said proximal end is downwardly tapered symmetrically along said longitudinal axis for ease of insertion.
Claim 5
Dependent Claim
33 words
A device of claim 2 wherein said distal end has a concave radial surface about said guides means' longitudinal axis to assist in gripping and positioning said guide means within the open wound.
Claim 6
Dependent Claim
48 words
A device of claim 2 wherein said exit holes in said proximal portion are of sufficient longitudinal distance from said lip to accommodate the depth of the wound to be closed and the particular tissue layer to be sutured, approximately in the range of 0.5 to 2 inches.
Claim 7
Dependent Claim
66 words
A device of claim 5 wherein said guide means available is a plurality of sizes having different radial diameters and different longitudinal lengths between said lip and said exit holes in said proximal end to accommodate the depth of the wound to be closed, the particular tissue layer to be sutured, and a patient's anatomy, said radial diameters approximately ranging from 0.1 inches to 1 inch.
Claim 8
Dependent Claim
43 words
A device of claim 2 wherein said guide means integrally formed of high density polyethylene, and having an indice located in an upper surface of said distal end to properly align said passageways with respect to walls of the wound to be closed.
