ABSTRACT:
A combination of electrical surgical apparatus includes a first electrical surgical apparatus having a first operative state and a second operative state. A conductor for conducting electrical energy to the first apparatus has first characteristics when the first apparatus is in the first operative state and has second characteristics when the first apparatus is in the second operative state. A sensor is coupled between the first apparatus and a second electrical surgical apparatus having a first operative state and a second operative state. The sensor is responsive to a change from one of the first and second characteristics of the conductor to the other of the first and second characteristics of the conductor to produce a transition signal. A switch coupled between the sensor and the second apparatus is responsive to the transition signal to change the state of the second apparatus from one of the first and second operative states of the second apparatus to the other of the first and second operative states of the second apparatus.
