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 the electrodes move relative to one another.

Claims

1. A removable electrode assembly for use with a forceps having opposing end effectors and a handle for effecting movement of the end effectors relative to one another, comprising:

a cover plate;

a housing having at least one portion which is removably engageable with at least one portion of the forceps;

a pair of electrodes attachable to a distal end of the housing, the electrodes being removably engageable with the end effectors of the forceps such that the electrodes reside in opposing relation relative to one another;

at least one stop member for controlling the distance between the opposing electrodes; and

wherein both the cover plate and the housing are removably engageable with the forceps.

2. A removable electrode assembly according to claim 1 wherein the forceps are disposed between the housing and the cover plate.
