Multifunctional devices having loop configured portions and collection systems for endoscopic surgical procedures and methods therefor

A collection system for collecting substances in 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 comprising

• a cutter including an elongate outer tubular member having a distal end for being introduced at the operative site through the narrow portal and a proximal end for being disposed external of the patient's body, a first cutting edge carried by said distal end of said outer tubular member, an elongate inner tubular member disposed in said outer tubular member and having a second cutting edge for cooperating with said first cutting edge to cut anatomical tissue and having a proximal end for being disposed external of the patient's body, said outer tubular member and said inner tubular member being movable relative to one another, and a handle at said proximal ends of said outer and inner tubular members for moving at least one of said outer and inner tubular members relative to the other of said outer and inner tubular members to move at least one of said first and second cutting edges past the other of said first and second cutting edges to cut anatomical tissue between said first and second cutting edges;
• and
• a collection bag enclosing an interior and being fixedly attached to said outer tubular member with said first and second cutting edges disposed in said interior of said collection bag, said collection bag having an opening therein providing access to said first and second cutting edges from external of said collection bag, said collection bag being movable, from external of the patient's body, from a collapsed position facilitating introduction of said collection bag at the operative site simultaneously with introduction of said first and second cutting edges at the operative site to an expanded position after introduction of the collection bag and the first and second cutting edges at the operative site to allow substances to be introduced in said interior of said collection bag through said opening to be cut by said first and second cutting edges.
