When communicating with doctors about the treatment plan, sometimes we hear the word electrosurgery. So, what do ordinary scalpels and high-frequency electrosurgery refer to, and what is the difference? Which one recovers faster?
What we call a common scalpel here can be understood as a mechanical scalpel that needs to be used in traditional surgery, such as blades, toothed forceps, surgical scissors, etc. When using these metal scissors, blades, forceps, etc. for surgery, the amount of bleeding is large. During the process, it is necessary to continuously absorb the exuded blood, the operation time is long, the operation is difficult, and the blood loss is large. When we use high-frequency electrosurgery for surgery, because of the characteristics of high-frequency electrosurgery, a certain degree of coagulation is performed while cutting with electricity, and the amount of surgical blood is significantly reduced. These advantages depend on the work principle of high-frequency electrosurgery.
The working principle of high frequency electric knife:
When the high-frequency electrosurgical knife cuts and separates the tissue, the high-frequency current generated by the electrode tip of the electrosurgical knife heats the tissue when it contacts the patient's body. By separating and coagulating the tissue, the purpose of cutting and hemostasis is achieved. Generally speaking, the electrocautery pen has 2 modes: electric cutting and coagulation. The yellow button is the electric cutting mode, and the blue button is the electric coagulation mode. The electrocution mode is mainly used to cut the skin. Generally, after the traditional scalpel cuts the epidermis and dermis, the electrocution mode is used to cut. The electrocoagulation mode mainly plays the role of hemostasis. Generally, the electrocoagulation mode is not used during skin incision, which may easily cause tissue damage and lead to delayed wound healing.
In the specific treatment plan, the surgeon will usually communicate with the patient in detail which treatment plan to use before surgery based on various factors such as the surgical site, aesthetics, and possible risks. The recovery is fast and needs to be determined according to the specific situation.
