Abstract: An improved laparoscopic suture knot pusher or a ligator comprising an elongated and slender shaft with both ends having specific functions. One end serves as the handle and the other is knot pusher forward guide end. The forward end tip is slightly convexed and has three hallowed-out spaces which receives and engages the throws and strands when the throw knot rundown process is activated delivering the throw knots through a trocar and tied intracorporeally at the surgical site. A method of knot tying is described in which a plurality of throws are executed all at one time extracorporeally on the two strands of the suture urging forward each throw knot in succession without a pause thereby eliminating the formation of loose knots but instead square knots are created and tightened at the surgical site.

Abstract: An apparatus used in simulating the human body cavity whereby an individual user can practice endoscopic surgical procedures by duplicating the operative steps performed on actual true to life condition for the purpose of learning the art and constantly improving the skill of eye-hand coordination and manual dexterity. The simulator is provided with open sides to gain access into the cavity for placement of objects simulating human organs which are then mounted and anchored inside the cavity for practice simulation in instrument manipulation.
