Laparoscopic cannula cone with means for cannula stabilization and wound closure.
A reusable cone suitable for use with existing laparoscopy cannulas was designed to provide means for sealing and stabilizing the operative site throughout the procedure, and for repairing the surgical site after the surgery is completed. The device consists of a moveable laparoscopic cannula cone fitted with suture holders. The cone contains tunnels terminating at its distal end that serve as passages for sutures loaded on a special needle to traverse the abdominal wall. When sutures are pulled into suture holders they stabilize the cannula and seal the puncture site. When sutures are tied at the end of the procedure, they achieve full-thickness closure of the operative site. The laparoscopic cannula cone stabilizes the cannula on the abdominal wall, maintains an air-tight seal, controls potential hemorrhage from the cannula puncture site, and achieves satisfactory closure of the surgical defect. Preliminary experience with the instrument and method has been most satisfactory.
