What is the difference between monopolar electrosurgery, bipolar electrocautery, and argon electrosurgery?
1. The monopolar high-frequency electrosurgical unit uses a circuit to cut and coagulate tissue. This circuit consists of a high-frequency oscillator and amplifier in the high-frequency electrosurgical unit, the patient, connecting wires and electrodes. In most applications, active leads and electrodes are used to output current to the surgical site.
2. Bipolar high-frequency electrosurgery usually uses the two ends of a pair of pliers or scissors as the two poles, which are used as the working pole and return pole in the monopolar high-frequency electrosurgery. in a small amount of tissue. Bipolar high-frequency electrocautery is mainly used for coagulation of fine tissue.
The main difference between unipolar and bipolar electrosurgery is that bipolar detects the contact resistance between the negative plate and the human body through the loop. If the resistance is too large, the negative plate will fall off, thus avoiding overheating and burning the skin. Monopolar does not have this function.
3. Argon knife, enhances coagulation, it can quickly and uniformly coagulate large bleeding surfaces such as capillary beds.
The wide application of high-frequency electrosurgery has relieved the pain of patients and improved the quality of medical care. High-frequency electrosurgery is an electrosurgical instrument that replaces mechanical scalpels for tissue cutting. It heats the tissue through the high-frequency high-voltage current generated by the effective electrode tip when it is in contact with the body, so as to realize the separation and coagulation of the body tissue, so as to achieve the purpose of cutting and hemostasis.
