Description

Hand-held bipolar hemostatic forceps device

Technical Field

The utility model relates to a surgical instrument, concretely relates to bipolar hemostatic forceps device of hand-held type.

Background

The cessation of blood during a surgical procedure is a very important component. There are several methods for physical hemostasis commonly used:

1. pressurizing, binding and stopping bleeding;

2. hemostasis by finger pressure;

3. tourniquet hemostasis;

4. filling to stop bleeding.

Along with the continuous development of the electrosurgery technology, the application of the high-frequency electrotome bipolar hemostatic forceps 3 to rapidly stanch blood wins a faster operation speed for the surgical operation, and is more favorable for the postoperative recovery of patients.

The high-frequency electric knife bipolar forceps (tweezers) has the hemostatic principle that high-frequency sine waves generated by a high-power high-frequency electric generator are released to tissues through the head ends of the forceps (tweezers), so that the tissues between the two ends of the electric coagulation forceps generate a heat effect to coagulate proteins in blood vessels and body tissues, and the hemostatic effect is achieved. Since the high-frequency current only flows between the electrodes of the electrocoagulation clamp, the use safety is very good. At present, the advanced electrotome workstation can realize the blood vessel hemostasis with the diameter of 8 mm. The common high-frequency electrotome is generally applied to the treatment of bleeding of artery and vein blood vessels or tissues with the diameter of 2-3 mm, and the treatment principle is that the length of a blood vessel cauterization area strives to reach 2-4 times of the diameter of the blood vessel cauterization area.

As described above, the application of bipolar hemostasis with high frequency electric knife brings excellent hemostasis effect and extremely fast hemostasis speed to the surgical operation, but the working principle thereof causes the following disadvantages: the high-frequency electrotome used for bipolar hemostasis needs dozens of watts to two or three hundred watts of power, so that a power supply with higher power is needed for supplying power, and the equipment is very heavy and is not easy to carry.
