Application of Electrosurgical Unit in Oral Tissue Repair
Electrosurgical Unit is the use of high-frequency alternating current technology to generate thermal effects within tissues and selectively destroy certain tissues. The radio frequency energy emitted by the host is concentrated in the electrodes, forming a complete circuit through the human body, reflux plate, and its circuit. According to different usage purposes, energy output can be divided into fully rectified output and partially rectified output. The former is suitable for tissue cutting, while the latter is suitable for coagulation. So, the electric knife cutting of soft tissue is achieved by evaporating and vaporizing the tissue cells that the electrode passes through. At the same time, if the intensity of the radio wave energy output is adjusted appropriately, using an electric knife to remove gums and other oral soft tissues will have no resistance and achieve a neat effect.
When using an electric knife for surgery, attention should be paid to the output intensity of the electric wave and it should be adjusted appropriately. The principle is "least effective". Excessive burn can easily burn adjacent soft tissues, while excessive weakness cannot effectively remove soft tissues. The cutting action should be accurate and rapid. Finger fulcrums can greatly increase accuracy. If too much tissue is cut, it can be cut in stages. However, two cuts of the same area should be separated by at least 10-15 seconds, which is conducive to the dissipation of heat energy and prevents tissue necrosis and burning.
Traditional surgical treatment involves excessive bleeding in the surgical area, blurred surgical field, long surgical process, significant postoperative swelling, and the need to remove sutures, resulting in increased patient visits. However,the use of Electrosurgical Unit for treatment results in less intraoperative bleeding, clearer surgical area, and shorter surgical duration. If there is more intraoperative bleeding, high-frequency "electrocoagulation" electrodes can also be used for hemostasis, usually without the need for suturing, reducing the number of patient visits, making it an ideal treatment tool. Nurses should fully prepare for surgery, provide psychological care to patients, comfort and encourage them, relax their emotions, maintain silence, and cooperate with medical staff during the surgery. To ensure the quality of surgery, one must be familiar with the nursing coordination in all aspects of the surgical process, be proficient in movements, accurate and in place, and cooperate harmoniously.
Kreici et al. found that during the cutting process of an electric knife, high-frequency current passing through the blade will generate lateral thermal effects in adjacent tissues. If the operator operates incorrectly or generates excessive lateral heat effects when setting up the electric knife, it can cause damage to adjacent tissues and affect the healing process of the tissue. Improper use of high-frequency electric knives can cause gum recession and root migration of the combined epithelium. But proper operation can completely avoid periodontal damage. There are also studies in China that have found that improper use of high-frequency electric knives has a significant impact on wound healing. The user manual for high-frequency electric knives contains concise usage precautions, which are important contents that operators must carefully read and follow.
