Abstract
A tissue and organ extractor is provided for use during laparoscopic surgical procedures. The extractor is generally rod-shaped, having a handle, an elongated shank with a central bore, and a flexible collapsible cone-shaped terminal end. The shank extends continuously between the handle and the cone-shaped terminal end. The cone-shaped end is the intra-abdominal end of the instrument and includes a generally circular open end. The handle includes a locking lever for locking a grasping instrument, which might be used to grasp tissue or organs, securely in place in relation to the extractor. In use, the surgeon inserts the extractor through a cannula and, using the grasping instrument, manipulates a tissue or organ into the open-ended, cone-shaped terminal end. The instrument used to manipulate the tissue may be locked into place in the shank of the extractor, and the extractor, instrument and tissue contained in the extractor may be removed from the abdominal cavity through the cannula. As it is being removed, the flexible cone-shaped end of the extractor envelops and compresses the tissue contained therein.
