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

Common Injuries and Prevention during High-frequency ElectrocauteryPreventive measures for plate burnsChoose a suitable high-frequency electric knife negative electrode plate, install the negative electrode plate correctly, and ensure that the size and area of the plate are appropriate. Ensure that the effective contact area is greater than 100 centimeters. Infants and children are prohibited from using specialized negative electrode plates for cutting and folding. Clean the skin of the bonding area before pasting the negative electrode board to reduce resistance.

How to judge the quality of a Electrosurgical Unit      Electrosurgical Unit has a wide range of applications in surgery. In addition to being widely used in general surgery, brain surgery, chest surgery, facial features, etc., it is also increasingly used in endoscopic minimally invasive surgery. Its advantages are fast cutting speed and coagulation effect.

Argon Plasam ESU are also be Used in Respiratory DepartmentThe department with the most widespread application of Argon Plasam ESU is the digestive department, and it is also the department with the most purchases of Argon Plasam ESU. In fact, Argon Plasam ESU can be applied in many departments, such as open surgery, minimally invasive gastrointestinal endoscopy surgery, respiratory surgery, and proctology surgery.There are two ways to treat with Argon Plasam ESU.

Argon Plasma ESU Surgery     In foreign countries, argon plasam esu is mainly used for endovascular intervention treatment of digestive endoscopy. With the emergence of this technical advantage, its use in endovascular intervention treatment of bronchoscopy has increased year by year and has become the mainstream technology in Germany.

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.

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.
