In modern surgical medicine, high-frequency electrosurgical units have become an indispensable high-tech tool, significantly enhancing both the efficiency and safety of surgical procedures. But what exactly is a medical high-frequency electrosurgical unit? How does it work? And what are its clinical advantages? Let us unveil the essence of this remarkable surgical instrument.

Medical high-frequency electrosurgical units are specialized surgical devices that utilize high-frequency alternating current (typically ranging from 200kHz to 3MHz) to achieve precise tissue cutting and rapid hemostasis during surgical procedures.

I. The Working Principle of Electrosurgery – Thermal Effects of Electric Current

The high-frequency generator inside an electrosurgical unit produces alternating current at 300kHz to 3MHz. This high-frequency current is uniquely capable of passing safely through human tissue without stimulating nerves or muscles.

When the current flows through tissue, electrical resistance generates heat, causing rapid vaporization of cellular water for precise cutting. Simultaneously, this thermal energy denatures proteins in blood vessel walls, creating a coagulative seal for effective hemostasis.

II. Components of an Electrosurgical System

A complete high-frequency electrosurgical system typically consists of:

High-frequency generator (power source)

Active electrode (surgical pencil)

Neutral electrode (return pad/dispersive electrode)

Footswitch (for hands-free control)

Intelligent control system (for safety & precision)

These components work in synergy to ensure safe, efficient, and controlled surgical procedures.

III. Superior Capabilities of High-Frequency Electrosurgical Units

Precision Cutting

By adjusting power output, electrosurgical units can adapt to different tissue types, enabling accurate dissection while minimizing thermal damage to surrounding healthy structures.

Instant Hemostasis

Simultaneous coagulation of small blood vessels during cutting significantly reduces intraoperative bleeding, enhancing surgical efficiency.

Infection Control

The high-temperature cutting process provides inherent bactericidal effects, while reduced direct tissue contact lowers contamination risks compared to traditional scalpels.

VI. Important Precautions for Electrosurgical Unit Use

While high-frequency electrosurgical units offer significant advantages, strict adherence to safety protocols is essential:

Parameter Optimization

Precisely configure power settings according to tissue type and surgical requirements

Return Electrode Safety

Verify proper adhesion of the neutral electrode (return pad) to prevent current concentration

Fire Prevention

Avoid use in flammable environments (e.g., oxygen-rich atmospheres or near anesthetic gases)

Equipment Maintenance

Conduct regular system checks and performance validation tests

Special Patient Considerations

Exercise extreme caution with pacemaker-dependent patients

Implement additional monitoring when necessary

Critical Reminder: Always follow manufacturer guidelines and institutional protocols to ensure patient and operator safety.
