Is A High Frequency Electrosurgical Knife Same As A Laser?

Time:2023-08-13 16:54:38

Strictly speaking, both high-frequency electrosurgery and laser work on the human body through cautery, but high-frequency electrosurgery uses high-frequency current to act on the lesion of the human body for cutting and coagulation. The energy source is current. It is an electrosurgical instrument that replaces the mechanical scalpel for tissue cutting. The high-frequency high-voltage current generated by the effective electrode end heats the tissue when it is in contact with the body, so as to realize the separation and coagulation of the body tissue.


The laser uses the high temperature of the laser to cut or stop bleeding. Because the energy sources of the two are different, the effects of cutting and coagulation are also very different. The high-frequency current only acts on the superficial layer, and the damage to the deep tissue is relatively small.


According to the needs and characteristics of different surgeries, high-frequency electrosurgery and lasers both play an important role and are used in surgeries in many types of departments. Relying on the feedback of the cooperative hospitals and the operating habits of medical staff, we continue to develop and innovate high-frequency electrosurgical unit. Now we have argon gas knife, multi-functional high-frequency electrosurgical unit, constant power adaptive electrosurgical knife, multi-functional double electrosurgical knife, Various types of electrosurgical knives, such as radiofrequency electrosurgery, bipolar electrocautery, and LEEP knives for gynecology.
