Electrosurgical Unit Working Principle

High-frequency electrosurgical generator is a device that replaces mechanical scalpel to cut tissue by using high-frequency electric current. It can be divided into monopolar and bipolar modes. It uses computer to control the cutting depth and coagulation speed during surgery, achieving the effects of cutting and hemostasis. High-frequency electrosurgical generator consists of a main unit, a monopolar knife, a bipolar forceps, a negative plate, a foot switch and other accessories. The working principle is:


  • Monopolar mode:

It uses the heat and discharge of high-frequency current to cut and coagulate tissue. The current forms high temperature, heat and discharge at the tip of the knife, making the contacted tissue quickly dehydrate, decompose, evaporate, and blood coagulate, realizing the functions of tissue decomposition and coagulation.


  • Bipolar mode:

The bipolar forceps contact the tissue well, and the current passes between the two poles of the forceps. The deep part of the tissue coagulates in a radial pattern, and the related tissue becomes a light brown small scab, without forming obvious electric arc. It can achieve good coagulation effect in both dry and wet surgical fields. Bipolar coagulation has basically no cutting function, mainly for coagulation, with slow speed, but reliable hemostasis effect and minimal impact on surrounding tissue.


Electrosurgical Generator Use

The electrosurgical generator has become a cornerstone in endoscopy, revolutionizing the way clinicians perform minimally invasive procedures. This sophisticated device is instrumental in cutting, coagulating, and ablating tissues during endoscopic interventions, offering precise control and enhanced safety.


In endoscopy, the electrosurgical generator utilizes electrical energy to produce high-frequency currents that can be applied through specialized instruments such as endoscopic probes or electrodes. This allows for controlled tissue manipulation with minimal damage to surrounding structures. Common applications include polyp removal, tissue resection, and hemostasis.


One key advantage of electrosurgery in endoscopy is its versatility. The generator provides various modes such as cutting, coagulation, and blended modes, catering to the diverse needs of different procedures and anatomical sites. This adaptability enhances the surgeon's ability to tailor the energy delivery for optimal outcomes.


Moreover, the electrosurgical generator contributes to procedural efficiency by minimizing bleeding and promoting quicker recovery times for patients. Its integration with endoscopic systems ensures seamless coordination with other components, such as video processors and light sources, creating a comprehensive platform for successful and precise interventions.


As technology continues to advance, the role of electrosurgical generators in endoscopy is poised to evolve, promising further improvements in surgical precision, patient outcomes, and the overall efficacy of minimally invasive procedures.
