Reasonable Application of ESUMedical high-frequency electric knives have been widely used in both open surgery and endoscopic surgery. Both types of electric knives have their own characteristics, and different electric knives are used to achieve surgical results for different lesions: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.

Ventilator Gas Switching Mode    Different types of ventilators have different ways of converting the inspiratory phase and the expiratory phase. At present, there are mainly four forms of breathing phase switching in ventilators, the most basic of which are pressure switching and volume switching.    1. Time switching.     Negative pressure ventilators use time switching. Modern time-switched ventilators are controlled by electronic circuits.

The Structure of Anesthesia Machine    Anesthesia machine is an indispensable equipment for clinical anesthesia. Its main structures include:    1. Gas source: mainly refers to the storage equipment that supplies oxygen and N2O, with liquid oxygen in steel cylinders or a central gas supply source. After the force regulator reduces the pressure to 343-392kPa, it is supplied to the anesthesia machine for use. Adjust the fresh air flow rate through the gas flow meter. To quickly inflate the breathing system. Equipped with a quick inflation valve.    2.

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.

Explanation of precautions when using electrosurgical unitElectrosurgical Unit is a device that almost every surgeon will come into contact with. When using it, the following points should be noted:1. Have an understanding of the principles of ESU cutting and coagulation.2. When using a electrosurgical unit, do not select the wrong mode. For example, do not choose the cutting and coagulation modes incorrectly. If you choose the cutting mode during coagulation, it will cause tissue cells to burn and die.3.

In fact, the "Leep" is Loop Electrosurgical Exception Procedure, which means cervical circular resection.
