High Frequency Electric Knife Power DetectionThe power detection methods of various high-frequency electric knife brands are slightly different, but the principles are similar and basically the same. However, it should be noted that the load resistance selected for testing single pole and double pole high-frequency electric knives is generally different.

Analysis of Polyp Treatment Using Argon Gas Knife under the MicroscopeGastrointestinal polyp carcinogenesis is a common type of digestive disease, and with the promotion of fiberoptic endoscopy, the detection rate of this disease has significantly increased. Clinical diagnosis of polyp cancer is often confirmed through endoscopic resection surgery, but there is no unified conclusion on whether surgical treatment is necessary.

The Difference between Electrosurgical Unit and Ultrasonic KnifeThe principle of electrosurgical unit cutting is to generate voltage and current at the tip of the electric knife, and generate high temperature when in contact with the skin to cut tissue.The application principle of ultrasonic knife is to convert electrical energy into mechanical energy through a special conversion device, and the mechanical energy transmitted in the form of sine waves acts on the metal knife head at the front end, causing the knife head to produce 50-100 μ The mechanical oscillation of m amplitude generates fri

Reasonable Application of Medical High-frequency Electric knife and Argon Plasma ESUMedical high-frequency electric knife and argon plasma ESU have been widely used in both open surgery and endoscopic surgery.Each type of electric knife has its own characteristics, and different electric knives are selected to achieve different surgical effects for different lesions1.Benefits of using medical high-frequency electric knives under endoscopy:Through the endoscope interface, the use of high-frequency electric knife under endoscope has obvious advantages, which can reduce a lot of unnecessary pain.

What is the Difference between High-Frequency Electrocautery and Electrocoagulation?Simply put, it is a surgical knife that generates a high-voltage current at the end of the electric knife pen through the device, which instantly heats the tissue and thus plays a cutting role.For high-frequency electrocautery, the basic functions are electrocautery and electrocoagulation.

The Difference between ESU and Ultrasonic Surgery SystemThe principle of electrosurgical unit cutting is to generate voltage and current at the tip of the electric knife, and generate high temperature when in contact with the skin to cut tissue.The application principle of ultrasonic knife is to convert electrical energy into mechanical energy through a special conversion device, and the mechanical energy transmitted in the form of sine waves acts on the metal knife head at the front end, causing the knife head to produce 50-100 μ.The mechanical oscillation of m amplitude generates frictional

                                                                                                  Render Medical Group CM-350A (Leep)"Leep knife" is not actually a knife, why is it called "Leep knife"? In fact, the "Leep" is Loop Electrosurgical Exception Procedure, which means cervical circular resection.

Electrosurgical Unit for Tonsillectomy InjuryThe tonsils are rich in blood vessels and wounds are prone to bleeding. More and more doctors choose thermal cutting instruments such as plasma, carbon dioxide laser, and ultrasound knife for surgery. Low temperature plasma knife is a highly regarded instrument with a working temperature of only 40-70 ℃, and it also has the functions of cutting, hemostasis, and ablation.

The Working Mode of Electrosurgical Unit1. Monopolar modeIn the monopole mode of the Electrosurgical Unit, a complete circuit is used to cut and solidify tissue, which consists of a high-frequency generator inside the high-frequency electric knife, patient electrode plates connected to wires, and electrodes. In most applications, current passes through the patient through effective wires and electrodes, and then returns to the generator of the high-frequency electric knife through the patient's electrode plate and connecting wires.2.

The Principle and Applicability of Bipolar Electrosurgical UnitHigh frequency surgical unit is divided into monopolar and bipolar. monopolar high-frequency surgical unit forms a circuit between the negative electrode plate and the knife pen. The following introduces the working principle and applicable surgery of bipolar electric knife:The principle of bipolar high-frequency electric knife is to provide high-frequency electrical energy to the body tissue through the two tips of bipolar forceps,causing the blood vessels between the two ends of the bipolar forceps to dehydrate and coag
