PURPOSE: An electric coagulation device is provided to allow surgery operation to be performed in a safe manner, while improving view of surgery operation by removing air bubbles generated during surgery operation. CONSTITUTION: An electric coagulation device is characterized in that a safety cap is used so as to prevent unnecessary injury, and the tissue of the part of the body to be operated is introduced into a protection device by using a negative pressure. The protection device is shaped as a tube having a blocked end, and has an aperture formed at a side surface of the protection device. The protection device has a metallic member arranged inside of the protection device, and a gap is formed between the protection device and the metallic member so as to transfer the negative pressure. The air bubble generated during operation is eliminated by the negative pressure, to thereby improve view of surgery operation.
