High-frequency electrosurgical knife use process:
1. Assess the patient, ask whether the patient wears metal, whether there is metal implant in the body, whether a permanent pacemaker is installed, and whether the patient's body is in contact with the operating bed, and whether it touches other devices the metal parts.
2. Prepare high-frequency electrosurgical equipment and sterile monopolar and bipolar coagulation lines.
3. Insert the power supply of the high-frequency electric knife into the three-phase electric socket.
4. Insert the foot switch port into the corresponding socket of the high-frequency electric knife.
5. Turn on the power switch of the high-frequency electric knife, let the machine conduct self-test, the circuit board will alarm, and the REM red light will flash.
6. Connect the return electrode, paste the return electrode plate on the appropriate position of the patient's body, the green light of REM will flash, and the alarm will be contacted.
7. Separate the electrode electrocautery and bipolar electrocautery line on the operating table, do not wrap them around metal instruments, and insert the interface end of the host into the corresponding socket of the high-frequency electrocautery.
8. Select the appropriate output power and output mode. Under normal circumstances, the output power of the operation is 30-70w.
9. The surgeon can use manual or foot control to test the output of the electric knife for backup.
10. During use, the nurse should use the electric knife cleaning sheet to remove the organic eschar on the electric knife head in time. When not in use temporarily, the electric knife should be placed in the insulating protective cover. Once the electric knife head is found to be malfunctioning, it should be replaced in time.
11. At the end of the operation, turn off the power switch, pull out the monopolar and bipolar power cords, remove the electrode plates, pull out the power cords, and clean the equipment.
The above is the introduction of the use process of high-frequency electrosurgery. Compared with traditional mechanical scalpels, high-frequency electrosurgery can greatly shorten the operation time, and can also reduce the amount of blood loss and blood transfusion of patients, thereby greatly reducing the complications after surgery. For patients, it can also reduce the cost of surgery, which is more cost-effective.
