Abstract
The tissue retrieval system deploys a tissue bag at the surgical site. The bag is supported by the system as tissue is placed within the bag and is closed to isolate the collected tissue and allow the bag and collected tissue to be removed from the body. The bag can be reopened and re-closed as desired through use of a guide bead and cord. The bead also facilitates removal of the collected tissue.
Claims20
A tissue retrieval apparatus comprising:
- an introducer tube having a longitudinally extending lumen;
- an actuator movable through the lumen of the introducer tube, the actuator having a proximal end and a distal end;
- a first support arm extending from the distal end of the actuator;
- a second support arm extending from the distal end of the actuator;
- a third support arm;
- a tissue bag having an open end and a closed end, the open end of the tissue bag releasably coupled to the first and second support arms;
- and
- a cord attached along a periphery of the open end of the tissue bag and to the actuator,
- wherein the third support arm extends from a first end at the distal end of the actuator to a second end adjacent the closed end of the tissue bag, and wherein the third support arm is positioned between the first and second support arms.
