CONTAINED TISSUE EXTRACTION DEVICE AND METHOD

摘要

A contained tissue extraction device for morcellating a tissue inside an intracorporeal cavity is disclosed. Particularly, the contained tissue extraction device includes serrated-blade wire segments that are sandwiched between an inner bag and an outer bag. The contained tissue extraction device may capture a target tissue such that a surgeon may pull the contained tissue extraction device taught through an incision that is smaller than the target tissue. The contained tissue extraction device allows a surgeon to morcellate the contained tissue by oscillating wire ends of the wire segments back and forth.

主权项

1. A tissue extraction device for being introduced into an incision to an intracorporeal region and for capturing and morcellating a target tissue of the intracorporeal region, the device comprising:
a non-permeable outer bag, the outer bag having a mouth; an inner bag lining the outer bag; a set of wire segments placed between the inner bag and the outer bag, the wire segments having ends that are disposed near the mouth; wherein each wire segment of the set of wire segments is arranged to be separately removable from their placement between the bags; and wherein the outer bag is tightenable around the target tissue by pulling the mouth out of the incision to a tightened configuration, and in the tightened configuration, the ends are motionable to cause the wire segments to pass through the inner bag to begin morcellating the target tissue.
