Background
A high-frequency electric knife (high-frequency surgical instrument) is an electric surgical instrument for replacing a mechanical surgical knife to cut tissues. The tissue is heated when the high-frequency high-voltage current generated by the tip of the effective electrode contacts with the body, so that the separation and coagulation of the body tissue are realized, and the purposes of cutting and hemostasis are achieved. The cutting speed is high, the hemostatic effect is good, the operation is simple, safe and convenient, compared with the traditional mechanical scalpel, the high-frequency scalpel is clinically adopted, so that the operation time can be greatly shortened, and the blood loss and transfusion of a patient are reduced, thereby reducing complications and operation cost; compared with other electric surgical instruments (such as a laser scalpel, a microwave scalpel, an ultrasonic scalpel, a water scalpel, a semiconductor thermosetting scalpel and the like), the high-frequency electric scalpel has the advantages of wide applicable surgical range, easiness in entering a surgical part, simplicity and convenience in operation, reasonable cost performance and the like.
Nowadays, it is increasingly used in various endoscopic procedures, such as: laparoscope, prostatectomy, gastroscope, cystoscope, hysteroscope and other operations. Since the high-frequency electric knife can cut and coagulate blood at the same time, the high-frequency electric knife is also commonly used in operations (such as abdominal duct ligation and prostate and urethral lump excision) which are difficult to access and implement by a mechanical knife. The coagulation effect of the high-frequency electrotome is outstanding, so that the high-frequency electrotome can be widely applied to diffuse blood seepage parts such as liver, spleen, thyroid, mammary gland and lung operations.
When a high-frequency high-voltage current generated by the high-frequency electric knife passes through a high-impedance tissue, heat is generated in the tissue, and the tissue is gasified or coagulated. During electrosurgical use, the resistance varies from 100 ohms to 2000 ohms. As the tissue coagulates, water in the cells vaporizes, drying the tissue, causing the resistance to increase and eventually the current to stop completely.
However, the following disadvantages exist in the use of the high-frequency electric knife at present:
as mentioned above, in the process of using the high-frequency electrotome, the current will burn the surrounding wound, so smoke will be dispersed at the wound, which will affect the judgment of the doctor, and result in inaccurate cutting and poor cutting effect.
