Function
Principle:
The electrical resistance of tissue through which current is passing leads to heat
generation. Through heat, tissue can be cut and bleeding staunched.

In monopolar electrosurgery, the tissue
coagulation occurs by applying a high
frequency alternating current, which generates
heat. The HF current flows from the acicular or
planiform "active" electrode (A) to the larger-
area "return plate" (P). At the surface of the
active electrode, high current density occurs,
producing so much heat that tissue coagulates
or is cut.
Active electrodes are monopolar forceps,
scissors and shaft tubes.

In its home position the jaw A1 is opened. On
operating the handle C, the jaw is closed. To
lock A1, operate the notch arm C2.
The shaft tube C can be rotated and can be
locked at 8 x 45° positions.
