Background

The bipolar coagulation forceps is one of medical instruments which are frequently applied in brain surgery and neurosurgery and is mainly used for performing electrocoagulation hemostasis on bleeding points when blood vessels bleed locally. Because the bipolar coagulation forceps are closed by the forceps clamps, the high-frequency current is conducted in the forceps bodies to achieve the purpose of hemostasis, and therefore high temperature can be generated in damaged parts in the hemostasis process, and tissue degeneration is caused. These denatured tissue deposits, on the one hand, can produce scarring after drying and, on the other hand, can cause adhesion between the forceps jaws and the blood vessels.

The existing treatment mode is that the auxiliary doctor or nurse waters with the thin water pipe to wash the forceps clip part, and the purpose is as follows: (1) the accumulation of the denatured tissues to generate coke scars is avoided, and (2) the blood is cleaned to keep the operation part clear and visible; however, the intracranial operation space is very limited, and the addition of the auxiliary personnel can limit the operation of the main surgeon and influence the operation effect.

In the scheme of using the drainage tube, different water pressures are needed to ensure that tissues and blood vessels are separated from the forceps clips due to different adhesion degrees of the tissues and the forceps clips, but the flushing water pressure in the operation is not high to ensure that the tissues are not damaged, so that the tissues, the blood vessels and the forceps clips can not be separated.
