Abstract
A surgical apparatus for removing tissue, which includes (i) an elongated body defining an opening at a distal end and forming a tissue receiving cavity in communication with the opening (ii) a blunt dilator at least partially disposed in the tissue receiving cavity and (iii) a cutting member operatively movable transverse to the elongated body in proximity to the opening.
Claims16
A surgical apparatus for removing tissue, which comprises:
- an elongated body defining an opening at a distal end, the elongated body further forming a tissue receiving cavity in communication with the opening;
- an elongated blunt obturator defining a longitudinal axis and being at least partially disposed in the tissue receiving cavity wherein the blunt obturator includes a plurality of spaced apart, axially aligned supports formed along an inner surface of the blunt obturator, which facilitate maintaining an elongated surgical instrument positioned in the elongated blunt obturator in a fixed orientation relative to the longitudinal axis;
- and
- a cutting member operatively movable transverse to the elongated body in proximity to the opening such that the cutting member cuts transversely across the opening.

A surgical apparatus for removing tissue, which comprises:
- a housing defining a longitudinal channel therethrough configured and dimensioned to receive surgical instrumentation therein;
- an elongated body which extends from the housing and forms an opening at a distal end, the elongated body further forming a tissue receiving cavity in communication with the opening;
- an elongated blunt obturator defining a longitudinal axis and being disposed in the longitudinal channel, wherein the elongated blunt obturator defines a longitudinal passageway therethrough, and includes a plurality of spaced apart, axially aligned supports formed along an inner surface of the blunt obturator, which facilitate maintaining an elongated surgical instrument positioned in the elongated blunt obturator in a fixed orientation relative to the longitudinal axis;
- and
- a cutting member operatively associated with the housing and movable transversely across the opening.

A surgical apparatus for removing tissue, which comprises:
- an elongated body defining an opening at a distal end, the elongated body further forming a tissue receiving cavity in communication with the opening;
- an elongated blunt obturator defining a longitudinal axis and being disposed within the tissue receiving cavity, wherein the elongated blunt obturator includes a plurality of spaced apart, axially aligned supports formed along an inner surface of the blunt obturator, which facilitate maintaining an elongated surgical instrument positioned in the elongated blunt obturator in a fixed orientation relative to the longitudinal axis;
- a tubular member movable relative to the elongated body, the tubular member having a cutting surface formed at a distal end thereof;
- and
- a tissue cutting member disposed adjacent the tubular member, at least a portion of the tissue cutting member being movable transverse to the elongated body in proximity to the opening such that the cutting member cuts transversely across the opening.
