SYSTEMS FOR REMOVING A TISSUE SPECIMEN OR ORGAN THROUGH A SMALL INCISION OR NATURAL OPENING IN A PATIENT

摘要

A system and method for facilitating the removal of a tissue specimen from a patient is disclosed. The system includes a bag or pouch, a tissue cutter device, a support and a stabilizer. The tissue cutter device includes a passer, a wire, and a handle. The support is an elongated member. The passer is an elongated member configured to be coupled to the support and introduced as a temporary unit into the mouth of the bag or pouch in the patient's body holding the tissue specimen. The wire is attached to the passer. The temporary unit is configured to pass around the tissue specimen and out of the opening in the bag or pouch to carry the wire through that path so that a distal portion of the wire and a proximal portion of the wire are outside the patient's body. Those portions of the wire can be pulled to cut into the tissue specimen. The stabilizer holds the tissue specimen as the wire cuts into it.
