High-frequency electrosurgical operation instrument

Abstract

The invention discloses a high-frequency electrosurgical operation instrument, which comprises a high-frequency generator and is characterized in that the high-frequency generator consists of a control circuit, a radio-frequency output circuit and a display circuit, wherein the radio-frequency output circuit is connected with an operation electrode, and the operation electrode and the control circuit form a control loop. By using the high-frequency electrical energy output by a main machine and combining the pressure of a vascular forceps port, collagen and fibrin in human tissues are dissolved and denatured, and vascular walls are fused to form a transparent zone so as to form permanent obliteration. No matter open operation or operation under an endoscope, the operation instrument can fully play a role in any vein, artery or tissue bundle with diameter of within 7 millimeters, and is safer, quicker and more convenient to close or cut the vein, the artery or the tissue bundle. An ultrasonic cutting hemostasis knife is difficult to achieve the advantages.

Description

technical field [0001] The invention relates to a medical instrument, especially a medical instrument for surgery, specifically a high-frequency electrosurgical instrument. Background technique In the history of surgical development, surgical bleeding is one of the important factors hindering the development of surgery. Surgical techniques or methods for seeking cutting and hemostasis have always run through the development of surgery, and various surgical instruments with cutting or hemostasis functions have also been launched one after another. Among them, the most representative one is the high-frequency electric knife, which uses high-frequency high-voltage arc cutting and coagulation to stop bleeding. It is also one of the commonly used equipment in modern surgery. However, because the temperature of the arc is as high as thousands of degrees, its thermal damage to biological tissues is very serious. The high-frequency electric knife is limited by its working principl...
