Vessel sealing forceps with disposable electrodes
First Claim
1. A bipolar electrosurgical instrument, comprising:
- a forceps having opposing end effectors and a handle for effecting relative movement of the end effectors with respect to one another;
an electrode assembly removably attachable to the forceps, the electrode assembly including a pair of opposing electrodes attached to a distal end thereof, each electrode of the pair of opposing electrodes removably engageable with one of the end effectors;
at least one stop member for controlling the distance between the pair of opposing electrodes, the at least one stop member selectively engageable with and operably coupled to at least one of the electrodes,wherein the at least one electrode that is selectively engageable with and operably coupled to the at least one stop member includes at least one corresponding aperture defined therein dimensioned to selectively engage the at least one stop member, the at least one electrode also including a conductive surface and an insulating substrate, wherein the at least one corresponding aperture is disposed on the insulating substrate and the at least one stop member protrudes from each of the conductive surface and the insulating substrate.

Abstract
A removable electrode assembly for use in combination with a forceps having opposing end effectors and a handle for effecting movement of the end effectors relative to one another. The electrode assembly includes a housing which is removably engageable with the forceps and a pair of electrodes which are attachable to a distal end of the housing. The electrodes are removably engageable with the end effectors of the forceps such that the electrodes reside in opposing relation relative to one another. The electrode assembly also includes a cover plate which is removably attachable to the housing and at least one stop member for controlling the distance between the opposing electrodes. The stop member is selectively engageable with the electrodes.
