Abstract
The present invention is directed towards a mechanical morcellator which includes a rotatable and relatively retractable cutting head. User manipulation varies the amount the cutting head extends out of a sheath, the amount of suction communicated to the cutting head, and the operation of a motor which rotatably drives the cutting head. Suction is communicated to the cutting head to aspirate the tissue fragmented by the cutting head. The morcellator is adapted to be inserted through a laparoscopic port site and directly fragment and aspirate tissue from within a patient's body. Alternate embodiments of the present invention provide different cutting head extension and retraction devices. The morcellator of the present invention allows removal of tissue without the need for large entry incisions.
