Abstract
A surgical tissue morcellator ( ) for percutaneously morcellating and debulking tissue during a minimally invasive, endoscopic surgical procedure. In an insertion configuration, the morcellator includes an outer cutting sheath ( ) and an insertion member ( ) inserted therethrough and positioned relative thereto via a connector ( ). The connector includes an adaptor ( ) positioned at the proximal portion ( ) of the outer cutting sheath. The adaptor includes a lock member ( ) such as a pin extending radially into the bore ( ) of the adaptor. A second lock member ( ) in the form of a T-shaped slot is formed in the surface of the insertion member to receive and position the pin therein. In a morcellation configuration, the morcellator includes a handle ( ) that is positioned in the bore of the adaptor. A tissue fixation member ( ) is inserted through the handle and outer sheath passages ( ) and includes a distal portion ( ) with a helical coil ( ) that extends from the distal cutting end ( ) of the outer cutting sheath for affixation to a tissue mass ( ). The tissue fixation member also includes a plurality ( ) of helical grooves ( ) of which a plurality ( ) of projections ( ) extend from the handle and into the grooves. These projections are positioned on the ends of a plurality ( ) of rocker arms ( ) which are pivotally mounted in the wall ( ) of the handle. The engagement projections are extended selectively into and out of the passage of the handle via a retainer ring ( ) that longitudinally slides on the neck portion ( ) of the handle.
