A morcellator is a surgical instrument used for division and removal of large masses of tissues during laparoscopic surgery. In laparoscopic hysterectomy the uterus is minced up, or morcellated, into smaller pieces inside the woman's abdominal cavity in order to extract from the abdomen. It can consist of a hollow cylinder that penetrates the abdominal wall, ending with sharp edges or cutting jaws, through which a grasper can be inserted to pull the mass into the cylinder to cut out an extractable piece.

Method and apparatus for tissue morcellation
InactiveUS20080255597A1Easy rotary cuttingFacilitate tissue cuttingDiagnosticsExcision instrumentsCoringSurgical department
The invention relates to a tissue morcellator for minimally invasive surgery. The morcellator has a metallic cutting ring mounted on a visually transparent hollow cylinder, which in combination with a visually transparent outer morcellator tube enables a surgeon to visualize the inside of the morcellator shaft for detection of loose tissue fragments in the device. A tenaculum used with the morcellation device has a spacer for preventing contact with the blade. The cutting tube can oscillate, rather than rotate, along the longitudinal axis of the cutting tube. The morcellator utilizes an extendable tissue guide on the outer tube of the morcellator shaft for preventing the tissue from rotating along the longitudinal axis of the morcellator tube. This allows the tissue to be continuously rotated into the morcellator device for continuous peel. The tissue guide can also be fully retracted to allow for coring of the bulk tissue.

System and method for laparoscopic morcellator
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.

Cutting blade for morcellator
InactiveUS20080039880A1Minimizing chanceLess expensiveExcision instrumentsEndoscopic cutting instrumentsSurgical siteEngineering
A cutting blade for a morcellator has a generally cylindrical shape and includes a sidewall having an inner surface and an outer surface, each of which at least partially resides respectively in concentric first and second cylindrical planes. The blade sidewall further includes a beveled or sloped surface that extends from the inner surface toward the outer surface to define a sharpened edge situated in the second cylindrical plane in which the outer surface of the cutting blade sidewall resides. The sloped surface is provided to protect the sharpened edge of the morcellator blade when it is not obvious to a surgeon operating the morcellator that a tenaculum used to grasp anatomical tissue at the surgical site may have its tissue grasping claws spread to such an extent that the claws may contact the cutting blade of the morcellator. Under such circumstances, the tenaculum will contact the sloped portion of the inner surface of the cutting blade, rather than the sharpened edge, thereby minimizing the chance that the sharpened edge will become dull or damaged.
