Electrosurgical pens
When patients undergo surgery, their bodies begin the healing process from the very first incision. The precision of that initial cut – and every cut that follows – directly impacts how quickly and completely they’ll recover.
- Electrosurgical pens are medical devices used in electrosurgery.
- Uses high-frequency electrical currents to cut, coagulate, or remove tissue.
- Used in dermatology, general surgery, oncology, plastic surgery, and more, to perform precise operations with minimal bleeding.
Electrosurgical pens enable surgeons to work with exceptional control, creating clean incisions that minimise tissue trauma, reduce blood loss and preserve the body’s natural healing pathways. When surgeons are equipped with tools that help them operate with confidence, patients benefit from fewer complications, faster recoveries, and a smoother return to life.
At Kingfisher Medical, we expose, not impose – guiding teams to the right tools without the push. We prepare, implement, and document every step. And once it’s in the surgeon’s hands, it’s not the end of the show, we stay close to support and keep things moving.
Key components of electrosurgical pens
Pen body
The pen is typically lightweight, ergonomically designed to provide the surgeon with easy handling and control.
Electrode tip
The tip of the pen contains the electrode that is used to apply electrical current to the tissue. The electrode may have different shapes for cutting, coagulating, or vaporising tissue.
Power source
The device is powered by an electrosurgical generator, which supplies high-frequency electrical current (typically between 200 kHz to 4 MHz). This current is what allows for the cutting or coagulation of tissue.
Control buttons
Modern electrosurgical pens usually have buttons or foot pedals to allow the surgeon to control the power settings and switch between cutting and coagulating modes.
How electrosurgical pens work:
Cutting mode
In this mode, the pen delivers a continuous electrical current to a small, focused area of tissue, generating heat that cuts through the tissue by vaporising the cells.
Coagulation mode
Here, the electrical current is delivered in a pulsed or intermittent manner, creating heat that causes blood vessels to coagulate and close, reducing bleeding.
Blend mode
This is a combination of both cutting and coagulation, used for more delicate procedures where both precise cutting and tissue sealing are needed.
Applications:
Surgical procedures: Electrosurgical pens are used in a variety of surgical fields, including general surgery, gynecology, urology, and plastic surgery, to perform cutting and cauterisation.
Dermatology: For removing lesions, warts, and other skin abnormalities.
Oral and maxillofacial surgery: To manage tissue during procedures like tumor removal or gum surgeries.
Advantages:
Precision: The focused electrical current allows for more precise cuts with less damage to surrounding tissues.
Reduced bleeding: The coagulation function helps minimise blood loss during surgery by sealing blood vessels.
Minimally invasive: Electrosurgery often allows for smaller incisions and quicker healing.
In summary
Electrosurgical pens are versatile tools in modern surgery, offering precision and efficiency in both cutting and coagulation during various medical procedures.
