As a high-frequency electrosurgical device, electrosurgical equipment plays an important role in surgery. It cuts and coagulates tissues through high temperatures generated by high-frequency currents, and has the advantages of less bleeding, shorter operation time, and faster postoperative recovery. However, the use of electrosurgical tools also comes with certain risks, among which the use of negative plates is particularly critical. This article will elaborate on the precautions for the use of the negative electrode plate of the electrosurgical unit to ensure the safety of the operation.
1. The function and principle of the negative plate.
The negative plate is an important part of the electric knife equipment, and its function is mainly to form a complete current loop. During the procedure, the high-frequency current generated when the electrosurgical pen cuts the tissue needs to be returned to the electrosurgical host through the negative plate to form a closed circuit. The negative plates are usually made of materials with good conductivity, such as metal or carbon materials, to ensure the smooth conduction of electric current.
2. Precautions for the use of negative plates.
Choose the right negative plate: Choose the appropriate size and shape of the negative plate according to factors such as the patient's body size, surgical site, and surgery time. Generally speaking, the larger the area of the negative plate, the more uniform the current distribution, and the smaller the damage to the negative. At the same time, it is necessary to ensure that the conductivity of the negative plate is good, and there is no damage or aging.
Correct Placement of Adhesives: The negative plates should be attached to the patient's muscle-rich, less vascular and proximity to the surgical site. Avoid sticking on bony protrusions, **broken, scarred or hairy areas, so as not to affect the conductive effect and increase the risk of injury**. For children, emaciated patients, or patients with special body sizes, special attention should be paid to choosing the appropriate placement of the application.
Preparation before pasting: Before pasting the negative plate, the patient's ** should be cleaned to remove grease, dander and other dirt. At the same time, make sure that it is dry and avoid using the negative plate when it is wet or sweating a lot. Areas with a lot of hair should be shaved first.
Make sure to stick tightly: When pasting the negative plate, make sure that it fits tightly with **, and there are no bubbles or wrinkles. You can use your fingers to gently press the edge of the negative plate so that it is in full contact with **. At the same time, it is necessary to avoid repeatedly tearing or moving the negative plate, so as not to damage ** or affect the conductive effect.
Intraoperative observation and adjustment: During the operation, the ** condition around the negative plate should be closely observed. If you find redness, blisters, burns and other abnormal phenomena, you should immediately stop using it and replace it with a new negative plate. In addition, if the procedure is longer or the patient is fatter, consider using multiple negative plates to disperse the current density.
Postoperative treatment and evaluation: After the operation, the negative plate should be removed in time and the patient's condition should be observed. If there is any abnormal situation, it should be dealt with and recorded in time. Patients are also evaluated postoperatively to understand the outcome of the procedure and complications.
3. Summary and outlook.
As an important part of electrosurgical equipment, the negative plate of the electrosurgical unit plays a vital role in the surgical process. Proper use of the negative plate not only ensures a smooth operation, but also effectively reduces the risk of complications. Therefore, it is necessary to fully understand and master the precautions for the use of the negative plate of the electrosurgical unit to ensure the safety of the operation. With the continuous development of technology, the performance of electrosurgical equipment and its accessories will continue to improve to provide safer and more efficient means for clinical operations.
