principle

^{[1] It} consists of a double-lobed tweezer body and an electrode holder. The tail ends of the double-lobed tweezer body are respectively connected to the electrode holder. The electrode holder is provided with a high-frequency input plug. The external surface of the double-lobed tweezer is provided with an insulating layer. A water channel is provided along the direction of the forceps body on the inside of any flap of the body. The front water outlet of the water channel is located at the conductive working tip of the tip of the valve forceps. The rear water inlet leads to the seal from the wall of the forceps body. Connect to the water delivery guide. The bipolar electrocoagulation forceps are embedded in the water channel formed by a water delivery catheter in the body of the tweezers, and the outlet of the water delivery catheter is close to the head of the bipolar electrocoagulation forceps. Therefore, the bipolar electrocoagulation forceps are electrocoagulated during surgery. During hemostasis, sterile saline will flow slowly and continuously through the water delivery catheter to the head of the bipolar electrocoagulation forceps, thereby preventing scarring.

Bipolar Electrocoagulation Forceps

Bipolar coagulation can perform finer electrocoagulation and hemostasis on small blood vessels and other structures. The principle is that the closed tissue of protein coagulated blood vessels can be heated to the coagulation and boiling point by heating, and the power can be automatically turned off. At the same time, due to the bipolar coagulation of the blade insulation, only the current is conducted between the tweezer tips. During the coagulation, the current flows from one tweezer tip to another tweezer tip. Affected or not affected, but has a protective effect on brain tissue. Bipolar coagulation also has the functions of separation and clamping. The effect of flushing can reduce the heat generation of the electrocoagulation, and can prevent the electrocoagulated tissue from sticking to the tip of the bipolar electrocoagulation. Bipolar coagulation during aneurysm surgery has a special effect on the success of the surgery, such as the neck shaping.

Advantages of bipolar coagulating forceps

The bipolar electrocoagulation forceps and the two tips of the lead wire ^[1] provide high-frequency power to the tissue of the lesion, dehydrating and coagulating the blood vessels between the two ends of the bipolar forceps to achieve the purpose of hemostasis. Because its scope of action is limited to only between the two ends of the forceps, the degree of damage to the adjacent tissues and the extent of its impact are small and quite safe.
