Abstract
A simple and reliable electrosurgical instrument includes a cable having a main contact wire and first and second insulated switch wires. The cable is received into a main member having three electrical terminals to secure the three wires to three electrically isolated conducting strips which are mounted longitudinally in a fluid-sealed switch assembly. The main contact wire is connected to the main conducting strip, and the first and second switch wires are connected to the first and second switch conducting strips. The main conducting strip permanently connects the main contact wire to a socket which receives a electrode blade. A switch device selectively connects the main conducting strip to one of the two switch conducting strips. When a user pushes one of two buttons mounted on the outside of the electrosurgical instrument, the instrument provides a cutting current or a coagulation current.
