Claims18
An instrument comprising:
- an elongate body portion defining a lumen and having a distal end and a proximal end, the elongate body portion extending along a longitudinal axis;
- an open member extending distally from the distal end of the elongate body portion, the open member defining an opening for receiving tissue, wherein the opening is defined by a plane that is perpendicular to a plane perpendicular to the longitudinal axis;
- a rotating drive shaft extending within the lumen;
- and
- a rotatable cutting member, a proximal end of the rotatable cutting member coupled to and extending distally of a distal end of the rotating drive shaft, the rotatable cutting member configured to rotate about the longitudinal axis to circumscribe a volume partially enclosed by the open member, wherein the rotatable cutting member consists of a single arcuate shaped cutting member.

An instrument comprising:
- an elongate body portion having a longitudinal axis;
- a hemispherical wall extending distally from a distal end of the elongate body portion, the hemispherical wall defining an opening for receiving tissue and a compartment for holding morcellated tissue, wherein the opening is defined by a plane that is perpendicular to a plane perpendicular to the longitudinal axis;
- a rotatable drive shaft disposed within the elongate body portion;
- and
- a cutting member extending distally from the distal end of the elongate body portion, a proximal end of the cutting member coupled to the rotatable drive shaft and extending distally of the rotatable drive shaft, the cutting member configured to circumscribe a volume about the longitudinal axis, wherein the cutting member consists of a single arcuate shaped cutting member.
