  • Patent number: 5190555
    Abstract: A device for the collection and removal of body tissue and/or parts in laparoscopic surgery having an elongated tubular member with proximal and distal extremities and a bore extending therethrough. A sack formed of a flexible material with an opening therein is secured by a rod inside the tubular member to the distal extremity of the elongated tubular member. A drawstring is secured to the sack and circumscribes the opening of the sack and controls the opening and closing of the sack. The drawstring extends into the bore and is connected to a slide mounted around the tubular member. A handle is secured to the proximal extremity of the tubular member and finger rings are secured to the proximal extremity of the slide. Movement of the slide towards the distal extremity of the tubular member opens the sack once inside the patient for receiving the tissue or body part, while movement of the slide in a distal direction causes the sack to close to capture the tissue or body part.
