Patent ID: 8308746

Claim:
A tissue morcellation device, comprising: a mechanical cutting mechanism, comprising: a handpiece; a first, outer cylindrical tube defining a lumen, the first, outer tube being connected to the handpiece; a second, inner cylindrical tube, the second, inner tube being positioned concentrically within the lumen of the first, outer tube, a distal end of the second, inner tube having a sharpened distal edge and being adjacent to a distal end of the first outer cylindrical tube; a mechanical gear mechanism in the handpiece configured to generate rotation of the second, inner cylindrical tube; and wherein the second, inner tube is configured to rotate in relation to the first, outer tube about a longitudinal axis of the second, inner tube to effect morcellation; and a singular curved tissue guide configured to be coupled to the first, outer tube; the curved tissue guide being extendable from a first, retracted position in which the curved tissue guide does not extend distally beyond the distal end of the first, outer tube to a second, extended position in which the curved tissue guide projects distally of the distal end of the first, outer tube.
