ABSTRACT:
A laparscopic method and instrument for suturing and ligation of tissue in a body cavity of a patient through trocar tubes inserted into the cavity. First forceps have a needle on the end of a movable jaw to pierce the tissue and pass a surgical thread through it. Second forceps have a movable jaw and a groove through the ends of both jaws and transverse to the pivotal axis of the movable jaw for advancing a loose tie in the surgical thread through a trocar tube and into engagement with the tissue and tensioning or drawing up the tie to close the tissue and produce a secure knot. Preferably, the jaws of both forceps each have therein a groove for guiding the thread to avoid tearing the tissue and blades for cutting the excess thread when the suture is completed.
