ABSTRACT:
A collection system for collecting substances within the body of a patient in operative procedures wherein access to an internal operative site in the patient's body is gained through a narrow portal in the patient's body includes a cutter and a collection bag attached to a distal end of the cutter. The cutter has the distal end for being disposed at the operative site through the portal, a proximal end for being disposed external of the patient's body, a cutting edge at the distal end for cutting anatomical tissue and a handle at the proximal end for moving the cutting edge to cut the anatomical tissue. The collection bag is disposed over the distal end of the cutter and has a closed distal end, a proximal end fixedly attached to the cutter, an interior receiving the cutting edge therein and a selectively openable, selectively closable access slot providing communication with the interior of the collection bag from external thereof. The collection bag has a collapsed position facilitating introduction of the collection bag and the distal end of the cutter at the operative site through the portal. The collection bag is movable, from external of the patient's body, from the collapsed position to an expanded position after being introduced at the operative site to allow substances to be introduced in the interior of the collection bag through the access slot to be cut by the cutter. The cutter has a lumen between the distal and proximal ends thereof connectable with a source of suction external of the patient's body to withdraw substances from the interior of the collection bag while the collection bag remains at the operative site.
