Abstract
A surgical instrument includes a handle and a disposable assembly which can be readily replaced after each operation or as necessary. The disposable assembly includes both an electrically heated scalpel blade and an electrosurgical active electrode which are mounted in a spaced parallel arrangement so that they can be used alternately by rotating the instrument by 180 degrees. The mounted ends of both the blade and the electrode are adapted to be received by separate terminals in the instrument handle so that the appropriate external power sources can be selectively connected thereto.
