Abstract:
1. A method of suture knot forming in an anatomical cavity during laparoscopic or endoscopic surgery utilizing a modified needle driver comprising: a. providing a modified needle driver comprising: b. providing, separate from said modified needle driver, a suture with a long end having a needle attached thereto and a short end having no needle attached thereto; c. providing a second needle driver, separate from said modified needle driver; d. grasping said long end of said suture with said second needle driver in a non-dominant hand; e. placing said modified needle driver on top of said suture held by said second needle driver in said non-dominant hand; f. actuating said slidable shaft to pivot said mobile jaw to said deployed position; g. while holding said suture long end with said second needle driver, crossing said second needle driver over said tubular shaft, proximal to said mobile jaw in said deployed position; h. using said second needle driver, looping said suture around said distal end of said tubular shaft in a first direction to form a loop with said suture while said mobile jaw is in said deployed position, thereby preventing said suture from sliding off said tubular shaft; i. grasping said short end of said suture with said modified needle driver between said fixed jaw and said mobile jaw; j. with said modified needle driver, pulling said suture through said loop made around said distal end of said tubular shaft to form a first throw of a first knot; k. pulling said long end and said short end longitudinally apart with both said modified needle driver and said second needle driver to tighten said first throw of said first knot; I. repeating steps d through k one or more times to form one or more additional throws of said first knot, wherein said one or more additional throws may be formed using said first direction or a second direction, opposite to said first direction to form a locking throw, wherein if two consecutive throws are formed in said first direction then a slipknot is made which allows said suture to be snugged down before a locking throw is made in said second direction.
