Bipolar electrosurgical unit

Abstract

A bipolar electrosurgical clamp includes an electrosurgical clamp and a prompting circuit module. The electrosurgical clamp has a first clamping portion and a second clamping portion that can mate with the first clamping portion for sintering a physiological tissue. The prompting circuit module includes a first terminal, a second terminal electrically connected to the first clamping portion, a prompting circuit, and a buzzer. The prompting circuit is electrically connected between the first terminal and the second terminal. The first terminal, the prompting circuit, the second terminal, the first clamping portion, the physiological tissue, and the second clamping portion can be sequentially electrically connected to define a current path. The prompting circuit provides an operating voltage according to the current change in the current path. The buzzer is electrically connected to the prompting circuit and adjusts the emitted sound according to the change in the operating voltage.
