How does an electroscalpel work?

An electroscalpel is a medical device that converts electrical energy into heat to cut or coagulate tissues and cauterize them at the same time, using currents that develop at frequencies above 200,000 Hz. This device is composed of a series of individual units that together form an electrical circuit, where the current flows from a generator to an active electrode through the tissue and then back to the generator by the action of an inactive dispersion electrode.

Nowadays, the electroscalpel, also called an electric scalpel or an electrosurgical unit, is used in many medical specialties such as cosmetic surgery, obstetrics, dentistry, orthopedics, dermatology and veterinary medicine, since it allows to cut and cauterize tissues quickly, significantly reducing bleeding and causing very little thermal damage, which in turn results in considerable time savings. In addition, it allows effective asepsis, reducing the likelihood of transmission of infections from diseased tissues to healthy tissues.

How is an electroscalpel composed?

The parts that make up the electroscalpel have a punctual and essential function to carry out the cutting or coagulation effect as necessary, among them we can mention:

  • Surgical electro generator: It is the one who produces the current, and where the frequency and power of the current that is transmitted to the tissues are configured.
  • Positive or active electrode: It’s the device the surgeon drives. The current coming from the electrosurgical generator flows through the positive electrode and then comes into contact with the patient’s tissue.
  • Negative or return electrode: This device dissipates currents from the patient safely. The plate, which corresponds to the negative charge generator can be metal, lead or disposable self-adhesive. It is located near where the incision is to be made, before the patient is placed on the stretcher.

Operation of an electroscalpel

The electroscalpel uses high-frequency electrical energy to generate heat in order to coagulate or cut tissues of biological origin. According to its structure it has two modes of operation. The monopolar mode of operation, where the active electrode is the one that intervenes in the process, since it concentrates the energy at the contact point. And the operation of bipolar mode involves the action of the two electrodes, and they are usually presented as a hemostatic clamp. Both perform pure and combined electrosection as well as electrocoagulation and heat production is achieved through the passage of an oscillatory electric current, concentrated in a small area.

This equipment circulates currents above 200,000 Hz up to 3 GHz, since these currents do not interfere with the nervous processes of the patient, this is achieved thanks to the use of an electric generator through two electrodes applied to the body; to generate controllable heat at the applied site, with which electrosection or electrocoagulation of tissue is caused, depending on the case. The electroscalpel produces a thermal effect caused by the high frequency alternating current used by the instrument, avoiding effects such as; the electrolyte effect or the faradic effect, which would occur if the current is used at frequencies below 200,000 Hz.
