Abstract
Embodiments of the invention provide a laparoscopic morcellating device and method for removing tissue from a body cavity. The morcellating device includes a containment mechanism having an aperture, a cutting mechanism designed to fit into an interior space of the containment mechanism and a retractor mechanism that is coupled to the cutting mechanism. The containment mechanism and cutting mechanism combination surrounds the tissue and the aperture of the containment mechanism is closed around the tissue. The morcellating device further includes a motor for actuating the retractor such that the cutting mechanism constricts and morcellates the tissue. The laparoscopic morcellating device further allows for torque balancing of the retractor mechanism, gas flow regulation of the body cavity, and safety feedback mechanisms that can alert the surgeon.
