发明名称 LAPAROSCOPIC SURGICAL LIGATION, REPAIR AND ELECTROSURGICAL COAGULATION AND CUTTING DEVICE
摘要 A laparoscopic surgical ligation, repair, and electrosurgical coagulation and cutting device (10) has a central passageway (16) with first (26) and second (40) parallel channels on opposite sides thereof. A suture (18) extends through the central channel passageway (16) and has a loop (20) with a slip knot (22) on the distal end and a pull (24) on the proximal end. By pulling on the pull (24) the loop (20) can be drawn tightly about a tissue (50) to be ligated. An electrosurgical wire (28), connected (36) to a power source, slidably received in the first channel (26), has an electrically insulated body (30) extending through the first channel (26) with an exposed wire hook (32) formed at the distal end thereof for grasping the tissue (50) to pull it through the suture loop (20). A ligation assist device, such as a hypodermic needle (44) for providing anesthesia to the tissue (50) to be ligated or an optical fiber (46) for carrying laser energy for fulgurating the ligated tissue (50) is slidably received in the second channel (40). In one form, a nesting tube (74) is provided in one channel (26) to receive a suture needle (72) attached to a loopless suture (18) to easily suture to a body cavity wall (75). In another form, a tapered handle (12) frictionally receives a suture needle (72) attached to a looped (20) and slip knotted (22) suture (18) to repair a tear or rupture in a body part (89) by suturing through one or more laparoscopies without tying ligature knots inside the body cavity. In a third form, a curved carrying device (92) in one channel (40) and a ligation assist device (76) in the other channel (26) permits ligation of large vessels (99) attached to a body part (110) by fibrous tissue (108).
