ABSTRACT:
The invention includes an electrosurgical scalpel and a suction/coagulating tool provided in a single surgical instrument. The scalpel assumes an extended position when the instrument is used in a cutting mode and a retracted position when the tool is used in a coagulating mode. A push button control directs either continuous electrical current to the scalpel or pulsed electrical current to the suction/coagulating tool. Suction can be provided during both the cutting and coagulating procedures to maintain a clear field of vision.
