Patent number: 5480404Abstract: A surgical tissue retrieval instrument has a collapsible pouch at the distal end of an elongated support tube for retrieving internal body tissue through a trocar tube. The instrument includes a belt which is formed into a loop slidably attached about the open end of the pouch. The belt is slidably extendable through the support tube for expanding the open end of the pouch to receive the tissue and retractable into the support tube for drawing the open end of the pouch closed to enclose the tissue in the pouch. The belt has an oblong, e.g., rectangular, cross section oriented with its larger cross-sectional dimension perpendicular to the plane of the loop to provide stability at the open end of the pouch and to enable use of the pouch in a scoop-like manner to place the tissue therein. A portion of the belt is thermally set into a curved configuration to urge the loop into a normally expanded shape with the belt extended from the distal end of the support tube.Type: GrantFiled: June 16, 1993Date of Patent: January 2, 1996Assignee: Ethicon, Inc.Inventors: Gene W.

Patent number: 5454821Abstract: A system for the application of knots in surgical suture material consists of a pre-knotted surgical suture means (1) and a surgical knot applicator. The pre-knotted surgical suture means (1) has a sleeve (10) open at both ends (12, 13) and a surgical suture material (15) such as thread, cord, etc., which suture material is tied around the sleeve (10) to produce a pre-knotted displaceable knot (18) and has a free end (16). The surgical knot applicator contains a shaft, whose distal end-zone comprises an opening corresponding to the diameter of the sleeve (10). The sleeve (10) inserted with its proximal zone (12) into this opening is pulled back into the interior space of the shaft with a pulling-in device. The suture and the knot (18) are pulled tight by moving the free end (16) of the surgical suture material (15) guided through the sleeve (10) in proximal direction (arrow) with a pulling device.Type: GrantFiled: December 8, 1993Date of Patent: October 3, 1995Inventors: Michael Harm, Bernard Hinsch, Christoph Walther
