ABSTRACT:
A surgical instrument, guide, and method capable of being used for closure of peritoneum fascia, occlusion of bleeding vessels such as inferior epigastric, and for all uses related to accurately passing suture material through a guide into tissue. A tip of a surgical instrument in a standard suture-
eedle-driving position with a sharp tip that opens and closes with the surgeon grasping suture material with the sharp tip is provided. Insertion of the tip/suture through tissue until the tip is seen through the peritoneum by direct vision begins the wound-closing procedure. The suture is released by opening and withdrawing the tip from the guide. The suture is recovered by using the guide to redirect the tip and puncturing the tissue opposite the first point of insertion. The tip grasps the suture and pulls the suture through the guide. The suture is pulled outside the wound, providing for rapid closure of the surgical incision. The guide is insertable within the wound to be closed and guides the surgical instrument at a predetermined angle from the longitudinal axis of the guide for optimum wound closure. The surgical instrument and method may be used to advantageously shorten and strengthen ligaments. For example, by gathering and reinforcing the round ligament that supports a woman's uterus with suture materials, surgeons can reposition and stabilize a retroverted uterus.
