Abstract
A morcellator is designed to comminute tissue. The morcellator includes a rotatable electrode and a drive system. The rotatable electrode has a resistance to the flow of an electrical current. The electrode is heated by the flow of the current through the rotatable electrode. The rotatable electrode is also rotated by the drive system as the rotatable electrode is heated by the flow of the current. The rotation and heating of the rotatable electrode enables the morcellator to comminute tissue.
Claims26
A morcellator, comprising:
- (a) a rotatable electrode having a resistance to a flow of an electrical current and being heatable by the flow of the current through the rotatable electrode;
- and
- (b) a drive system for rotating the rotatable electrode as the rotatable electrode is heated by the flow of the current.
A method of morcellating tissue, comprising:
- (a) heating a rotatable electrode having a resistance to a flow of an electrical current by the flow of the current through the rotatable electrode;
- and
- (b) rotating the rotatable electrode as the rotatable electrode is heated by a flow of the current to comminute tissue.
A morcellator, comprising:
- (a) means for heating a rotatable electrode having a resistance to a flow of an electrical current by the flow of the current;
- and
- (b) means for rotating the rotatable electrode as the rotatable electrode is heated by the flow of the current.
