First Claim
1. An endoscopic surgical apparatus comprising:
- a frame;
a tubular shaft attached to said frame, the tubular shaft having a distal end and a proximal end;
means for ligating;
means for cutting;
a handle attached to said frame;
trigger means mounted on the frame for actuating the ligating means and cutting means; and
,clutch means mounted in the frame for switching the trigger means between a first mode for actuating said ligating means and a second mode for actuating said cutting means wherein when said trigger means is in said second mode, said ligating means is incapacitated.

Abstract
An endoscopic surgical apparatus capable of ligation and division. The apparatus has a frame and a tubular shaft attached to said frame. Also attached to the frame is a handle. The apparatus has ligating means and cutting means. Actuation means are mounted to the apparatus for actuating both the ligating means and the cutting means. The apparatus has a clutch means capable of enabling the actuating means to switch between a first mode for actuating the ligating means and a second mode for actuating the cutting means. The cutting means is preferably an extendable J-hook and blade assembly. The cutting means and ligating means are preferably rotatable with respect to the frame. The ligation and division apparatus may be used to ligate and cut blood vessels or tissue in a mammalian body cavity during a surgical procedure.

25. A method of ligating and cutting mammalian tissue or blood vessels comprising:
-
inserting the distal end of an endoscopic surgical apparatus into the body cavity of a mammal, wherein the apparatus comprises; a frame; a tubular shaft attached to said frame, the tubular shaft having a distal end and a proximal end; means for ligating; means for cutting; a handle attached to said frame; trigger means mounted to the frame for actuating the ligating means and cutting means; and
,clutch means mounted in the frame for switching the trigger means between a first mode for actuating said ligating means and a second mode for actuating said cutting means; applying at least one ligating clip to the tissue or blood vessel; using the clutch means to switch the actuating means to a cutting mode; engaging said tissue or blood vessel in said cutting means; and
,actuating the cutting means to cut said tissue or blood vessel. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
