A high-frequency electrosurgical unit is a surgical device that uses high-frequency discharge to cut and coagulate human tissue. High-frequency electrosurgical units offer advantages such as clean cuts, rapid hemostasis, good results, simple operation, convenience, time savings, and the ability to interrupt tumor blood supply and metastasis. Clinically, the use of high-frequency electrosurgical units can significantly shorten surgical time, reduce patient blood loss and transfusion volume, thereby reducing complications and surgical costs. However, high-frequency electrosurgical units are also high-power, high-frequency, high-voltage electronic devices that directly affect the human body, posing safety concerns. Improper operation can lead to burns, poor wound healing, interference with cardiac pacing, combustion, or explosion.
① Check the patient's skin integrity before and after use and record any abnormalities.
② Prevent short circuits, combustion, or explosions caused by the electrosurgical unit that could lead to patient burns.
③ When disinfecting the patient's surgical area with iodine or alcohol, the alcohol must be completely dry and evaporated before draping, applying surgical film, and using electrosurgical equipment; used alcohol gauze balls should be promptly removed from the surgical field.
④ Mannitol enemas are contraindicated in intestinal surgery, and electrocautery is prohibited for intestinal incisions in patients with intestinal obstruction to prevent explosions.
⑤ Protect the skin and prevent potential skin damage such as epidermal damage, subcutaneous hemorrhage, and pressure injuries. Correctly remove the negative electrode plate by slowly peeling it from the edge in the direction of the skin lines. If the negative electrode plate is removed too quickly or with excessive force, it can cause separation of the epidermis and dermis or mechanical damage such as epidermal peeling.
⑥ Do not use the electrosurgical unit near the electrode.
① Wear insulated gloves and dry, well-insulated shoes and shoe covers.
② Avoid using the electrosurgical unit when not in contact with the target tissue, otherwise, arc burns may occur.
③ If the effect is poor or the unit does not work normally under normal power, do not blindly increase the output power. First check the contact and connection between the negative electrode plate and the patient. The power should be adjusted gradually from low to high.
④ The resulting smoke and particles are harmful to the human body and should be promptly removed.
⑤ When the electrosurgical pencil or bipolar coagulation is not in use, it should be placed in an insulated container, not in a place that hinders the doctor's operation or on the patient's exposed body surface, to avoid accidental triggering causing burns to the patient or staff.
⑥ Keep the surgical incision drapes dry.
⑦ Remove the eschar tissue from the electrosurgical tip in time, keep the electrosurgical unit clean and dry. After use, the electrosurgical pencil can be wiped clean with a damp cloth. Avoid direct soaking in water.
⑧ Select the appropriate negative electrode plate Specification and Model, and place it appropriately.
⑨ Disposable negative electrode plates should not be reused.
⑩ Do not silence the alarm system. If abnormal sounds are emitted, stop using the equipment immediately and check the cause.
IV. Common Malfunctions
④ Circuit board damage, main control board damage.
