US 2010/0160912 A1 · Bipolar Tissue Debrider and Method

Abstract

A debrider apparatus is disclosed. The debrider includes a first tubular member that is adapted to connect to a first potential of an electrosurgical generator. A second tubular member is at least partially disposed within the first tubular member and is adapted to connect to a second potential of the electrosurgical generator. At least one tubular member is selectively movable relative to the other. A first set of teeth is disposed around at least a portion of a distal periphery of the first tubular member. A second set of teeth is disposed around at least a portion of a distal periphery of the second tubular member. At least one switch is operably coupled to at least one of the tubular members and activates movement of one tubular member and supplies respective electrical potentials to the tubular members.

Dependent claims

A system for shearing and electro surgically treating tissue, comprising:

a debrider apparatus including a first tubular member having a first set of teeth disposed circumferentially around about 25% to about 75% of a periphery of the first tubular member, the periphery adjacent a distal portion thereof, and a second tubular member having a second set of teeth disposed adjacent a distal portion thereof;
the second tubular member at least partially disposed within the first tubular member and at least one of the first and the second tubular member being selectively movable relative to the other;
and
an electrosurgical generator that supplies the first tubular member with a first electrical potential and supplies the second tubular member with a second electrical potential.
