Morcellator
First Claim
Patent Images
1. A surgical apparatus for morcellizing body tissue, which comprises:
- a) an endoscopic portion including an elongated tubular member having an axial bore, and an elongated auger rotatably disposed within the axial bore, the tubular member having an aperture which provides access for body tissue to contact the auger, and a cover member movable between a first position wherein the aperture is covered and a second position wherein the aperture is uncovered; and
b) a housing portion engaged with the endoscopic portion and including a rotary driver mounted therein, the rotary driver being operatively associated with the auger, and an actuation member responsive to user contact for actuating the rotary driver, wherein actuation of the rotary driver causes rotation of the auger.

Abstract
An endoscopic morcellator includes a tubular portion with an elongated auger rotatably positioned within its bore. An aperture near the distal end of the tubular portion permits access for body tissue to contact the auger. The auger is driven by a reversible motor which is powered by a battery pack. A container collects morcellized tissue which is aspirated by means of a suction tube.

15. A surgical apparatus for morcellizing body tissue, which comprises:
-
a) an endoscopic portion including an elongated tubular member having an axial bore, and an elongated auger rotatably disposed within the axial bore, the tubular member having an aperture which provides access for body tissue to contact the auger, and a cover member movable between a first position wherein the aperture is covered and a second position wherein the aperture is uncovered, wherein the cover member is resiliently biased to the closed position by a resilient member; and a housing portion engaged with the endoscopic portion and including a rotary driver mounted therein, the rotary driver being operatively associated with the auger, and an actuation member responsive to user contact for actuating the rotary driver, wherein actuation of the rotary driver causes rotation of the auger.

19. A method for morcellizing body tissue, comprising:
-
a) providing a morcellizing apparatus which includes i) an endoscopic portion including an elongated tubular member having an axial bore, and an elongated auger rotatably disposed within the axial bore, the tubular member having a distal end and an aperture spaced apart from the distal end for providing access for body tissue to contact said auger, and a cover member movable between a first position wherein the aperture is covered and a second position wherein the aperture is uncovered, said cover member being biased to said first position by a resilient member, and ii) a housing portion engaged with the endoscopic portion and having a rotary driver mounted therein, and an actuation member responsive to user contact for actuating the rotary driver, wherein actuation of the rotary driver causes rotation of the auger; b) forming an incision in a wall of body tissue; c) inserting the distal end of the elongated tubular member through the incision; d) positioning said cover member in said second position; e) positioning the distal end of the tubular member such that the aperture is adjacent body tissue to be morcellized and at least a portion of the auger comes into contact with the body tissue to morcellized; and f) rotating the auger such that the body tissue to be morcellized is drawn into the tubular member morcellized, while permitting said cover member to move from the second position to the first position in response to biasing force applied by said resilient member. - View Dependent Claims (20, 21, 22, 23, 24)
