Yu Juan and An Yani from Yantai Yuhuangding Hospital in Shandong Province published an article titled "Advantages of double-circuit Return Electrode Plates in High Frequency Generator" in the *Journal of Qilu Nursing*. The article mentioned that high frequency generator heats the tissues when it comes into contact with the body through the high-frequency and high-voltage electric current generated by the tip of the effective electrode, which achieves the separation and coagulation of the tissues of the body and thus serves the purpose of cutting and hemostasis. Due to the physical properties of electrical currents, the current acting on the human body must return to the high frequency generator via the return electrode plate to form a complete circuit.
The return electrode plate (also known as the neutral or dispersed electrode) is a critical component used in electrosurgery in conjunction with the High Frequency Generator. Its primary purpose is to establish a safe circuit for the electric current, to ensure that the high-frequency current from the monopolar electrode through the patient's body can be safely returned to the generator, to avoid accidental burns. Its core functions include the most basic to provide a low-impedance path for high-frequency current to form a closed circuit, preventing the current from spreading in the body in an uncontrolled manner; secondly, reducing current density by increasing contact area, thereby minimizing localized temperature rises and lowering the risk of thermal tissue damage.
The Disposable Patient Return Electrod provided by ShouLiang-med is professionally designed with key performance advantages to ensure surgical safety:
1.Excellent flexibility and strong adhesion ensure a stable and effective contact area between the patient and the electrode during surgery.
2.The conductive foil in the center is evenly divided into two sections. Once applied to the skin, the return electrode monitoring system in the high-frequency surgical device continuously evaluates the contact status. If any abnormality is detected, the system will trigger an audio-visual alarm and automatically stop output, ensuring real-time monitoring of effective patient connection.
3.With nearly zero resistance and low thermal effect, the electrode features a rounded rectangular shape that promotes even heat distribution, significantly reducing the risk of burns.
4.Designed for single use, it prevents cross-contamination between surgical patients and greatly enhances procedural safety.
