ABSTRACT:
A collection system for collecting substances within the body in endoscopic operative procedures wherein access to a site in the body is obtained through a narrow portal in the body includes an elongate inner tubular member, an elongate outer tubular member receiving the inner tubular member, a collection bag carried by a distal end of the inner tubular member and a suction cutter disposed in the inner tubular member. The collection bag has a non-expanded position wherein the collection bag is disposed within the outer tubular member to facilitate introduction of distal ends of the outer and inner tubular members through the narrow portal. The collection bag is movable from the non-expanded position to an expanded position within the body, the collection bag in the expanded position being disposed externally of the outer tubular member to allow substances to be introduced in the collection bag. The suction cutter has a distal end disposed within the collection bag, a proximal end and a suction channel between the distal and proximal ends of the suction cutter. The suction channel is connectible with a source of suction externally of the body to withdraw the substances introduced in the collection bag while the collection bag remains in the body.
