Abstract
An electrosurgical instrument, such as a scissors, in which the handle and blade members are of a conventional construction. Each blade member supports a detachable cartridge member made of an insulating material and supporting at least one electrode. The cartridge members do not interfere with the cutting engagement of the blade members. Each cartridge member can also permit relative movement between its electrode and associated cutting edge from a first position in which the electrodes are between the cutting edges (when the blades are open) to a second position in which each electrode is behind its respective cutting edge (as the blades are closed).
