Unveiling the mysterious "veil" of high-frequency electrosurgical pencil

High-frequency electrosurgical pencil is a surgical instruments that replaces mechanical scalpel for tissue cutting. It heats the tissue through the high-frequency high-voltage current generated by the effective electrode tip when it contacts with the body, achieving the purpose of cutting and hemostasis by separating and coagulating the body tissue. Due to its ability to simultaneously perform cutting and coagulation, ESU pencil is widely used in surgeries where mechanical scalpel is difficult to enter and perform, such as abdominal duct ligation and prostate urethral tumor resection.

Before the advent of ESU pencil, surgical incisions were made with blades. With the development of medical technology, the high-frequency electrosurgical pencil was introduced as a medical device. Its appearance not only replaces the cutting function of blades, but also increases different levels of coagulation function. The use of high-frequency electrosurgical pencil in surgery can reduce bleeding, shorten operation time, and also reduce the number of sutures used in the incision to reduce the scar formation.

As a medical device, high-frequency electrosurgical pencil is widely used in diffuse bleeding sites such as liver, spleen, thyroid, breast, lung surgery due to its outstanding coagulation effect, and is increasingly used in various endoscopic surgeries such as laparoscopy, prostatectomy, gastroscopy, cystoscopy, hysteroscopy, etc.

For the safety of the surgery, there are some precautions before the surgery. As a surgical patient, you must pay attention!

If there are metal implants such as steel plates, steel nails, metal dentures, or cardiac pacemakers in the body, please inform the attending physician and operating room nurses truthfully. They will use high-frequency electrosurgical pencil appropriately based on the surgical site and the positional relationship of the metal implants to ensure surgical safety.

Patients with cardiac pacemakers generally cannot use high-frequency electrosurgical pencil, as high frequency will interfere with the cardiac pacemaker, causing it to work abnormally or even stop. If it is necessary to use, it should be carried out under the guidance of a cardiac physician.
