Abstract:

A morcellation system includes a morcellator and a grasper. The morcellator includes a housing and a tube extending from the housing and having at least one blade section. The morcellator further includes an oscillating mechanism configured to oscillate the tube. An end cap is coupled to the proximal end of the housing and is configured to receive the tube. The end cap defines a passage and includes an aligning structure disposed in the passage. The grasper includes a tubular member having a grasping end including first and second jaws moveable relative to one another. The grasper further includes a handle assembly operatively associated with the grasping end. A keyed collar is disposed about the tubular member. The keyed collar includes a key configured to cooperate with the aligning structure of the end cap to align the first and second jaws relative to the distal end of the tube.
