Laparoscopy instruments and method for suturing and ligation

Abstract

Abstract An improved combined laparoscopic needle and forceps comprising an elongated parallelogram type of linkage suitable for insertion through a trocar and having first and second ends, a needle, means for mounting said needle on said first end for movement from a position in substantial alignment with said linkage, which permits it to pass through a trocar, to a position transverse to said linkage, handle means on said second end of said linkage for actuating said linkage to effect movement of said needle, and a forceps construction including jaw means mounted proximate said first end of said needle linkage and being formed from a portion of said linkage and a portion of the holder of the needle. An improved combined laparoscopic forceps, suture guide and cutter comprising an elongated parallelogram type of linkage which is sufficiently slender for passage through a trocar and having first and second ends, jaw means on said first end, and handle means on said second end for actuating said linkage to move said jaws, groove means associated with said jaws for receiving a suture to thus act as a suture guide, and cutter means mounted on said jaws for cutting a suture. An improved laparoscopic ligator comprising an elongated stem having first and second ends, a handle at said first end and suture guiding means at said second end, said suture guiding means being of substantially the same cross sectional dimension as said elongated stem for guiding a suture through a trocar. An improved method of performing a surgical operation by laparoscopy comprising the steps of inserting at least first and second trocars through the body of a patient at spaced locations, inserting a first instrument comprising the above described combined laparoscopic needle and forceps through said first trocar, inserting a second instrument comprising the above described laparoscopic forceps, suture guide and cutter through said second trocar, manipulating said first and second instruments in cooperating relationship with each other in a predetermined area to the central portion of a suture in position, withdrawing one of said instruments to bring the end of the suture outside of the patient''s body, tying a knot in the suture outside of the body, and bringing the knot into the desired position by means of said laparoscopic ligator.
