Bipolar electric coagulation forceps for neurosurgery operation and bipolar electric coagulation forceps water cooling method

Abstract

The invention discloses a pair of bipolar electric coagulation forceps for a neurosurgery operation and a bipolar electric coagulation forceps water cooling method. The pair of bipolar electric coagulation forceps comprises a double-valve forceps body and an electrode seat, wherein an insulating layer is arranged on the outer surface of the double-valve forceps body; a sharp electrode is exposed out of working ends of the double-valve forceps body; tail ends of the double-valve forceps body are fixed with the electrode seat; the double-valve forceps body is conducted with an electric wire in the electrode seat; the electric wire is connected with a high-frequency input plug; the double-valve forceps body is further provided with a water system with a cooling function. The method comprisesthe following steps: introducing sterile normal saline into the double-valve forceps body, cooling the sterile normal saline, electrifying and carrying out sewing operation. According to the pair of bipolar electric coagulation forceps, disclosed by the invention, the sterile normal saline is mainly cooled through a cooling inner core and the temperature can be rapidly adjusted to be about 4 DEG Cwhen the operation is started, so that the temperature of the sterile normal saline washed out by points of the bipolar electric coagulation forceps is reduced; low-temperature water is dropped to abrain surface and can continuously cover an operation part along the operation, so that functions of reducing the temperature of brain tissues and effectively protecting the brain tissues are realized.

Description

technical field [0001] The invention relates to bipolar electric coagulation forceps for neurosurgery, and belongs to the technical field of medical instruments. Background technique [0002] Bipolar electrocoagulation can perform finer electrocoagulation and hemostasis and treatment of small blood vessels and other structures. The principle is to coagulate proteins and close blood vessels by heating. When the tissue is heated to the freezing point or boiling point, the power can be automatically cut off. At the same time, due to the insulation of the blades of bipolar coagulation, only the tweezers conduct current between the tweezers. During coagulation, the current flows from one tweezers tip to the other tweezers tip, and the tissues of the two tweezers are affected by the thermal effect of the current, while there is little tissue outside the tweezers tip. Whether it is affected or not, it has a protective effect on brain tissue. However, as the operation progresses, d...

Problems solved by technology

However, as the operation progresses, different parts of the brain tissue are continuously affected by electrocoagulation heat production, resulting in a continuous rise in the temperature of the entire brain, which seriously affects the recovery of brain function after surgery.
