RF thermocoagulator - Beiqi R-2000B RF operation
The R-2000B series RF thermocoagulator is developed and manufactured by Beijing Beiqi Medical Technology Co., Ltd. It has been widely adopted in thousands of hospitals across China, with applications primarily in departments such as pain management, neurosurgery, rehabilitation, and orthopedics. The device is often used alongside consumables like RF electrodes for cervical and lumbar spine procedures, as well as disposable RF trocars.

Operating Procedures:
1. Connect the negative electrode to the machine and attach it to the patient's body, ideally as close as possible to the needle insertion site. Connect the positive wire to the electrode and insert the electrode needle into the previously placed trocar.
2. Turn on the device. After a short period, the impedance value will be displayed on the screen.
3. Once the impedance reading is confirmed to be normal, press the “Stimulus†button.
4. For quick motor nerve stimulation: Press the “Stimulus†button. The screen will show 1.00V at 100Hz. Press “F1†to change the settings to 000V at 2Hz. Then press “Start†to begin the electrical stimulation. Adjust the knob to gradually increase the voltage up to 2.0V. If the patient does not experience muscle twitching at 2.0V, it indicates that the needle is not near the motor nerve, ensuring safety. This confirms the absence of motor nerve contact.
After completing the motor stimulation, press “Stop.†Press “F1†again to switch to sensory nerve stimulation. The screen will display 000V at 50Hz. Press “Start†and adjust the knob to increase the voltage up to 2.0V. If the patient feels no discomfort or overstimulation, it means the needle is not near the sensory nerve, confirming safe placement.
5. For rapid coagulation: After confirming the stimulation is safe, press the “Hot Curd†button. The screen will prompt for a temperature setting (e.g., 40°C for 60 seconds). Rotate the knob—when the step button indicator is lit, each rotation increases the temperature by 0.5°C; when it’s off, each rotation adds 5°C. Once the desired temperature is reached, press “Start†to begin heating. You can press “Stop†at any time.
6. Temperature settings for disc herniation treatment:
- 60°C for 1 minute
- 70°C for 1 minute
- 80°C for 1 minute
- 90°C for 1 minute
- 95°C for 3–5 minutes
During treatment, patients may feel warmth at the target site but should not experience severe pain. As long as they can tolerate it, the procedure is generally safe and does not damage nerves. If the patient finds it uncomfortable, the electrode can be repositioned inside the intervertebral disc.
7. For trigeminal neuralgia treatment:
- Sensory nerve stimulation: Voltage ranges from 0–0.5V at 50Hz.
- Motor nerve stimulation: Voltage ranges from 0–0.5V at 2Hz.
For heat settings during treatment, start from 50°C, then 60°C, 65°C, 70°C, and 80°C (highest), each for three minutes.
If the device triggers an alarm during operation, a digital code will appear on the screen. Refer to the manual for troubleshooting. If any settings seem incorrect, always verify based on the actual clinical situation.
RF Thermocoagulation Features:
- **Electrical Impedance Test**: Based on the impedance values of different tissues, doctors can determine whether the needle is positioned correctly. The following are reference impedance values:
| Tissue | Impedance (Ω) | Tissue | Impedance (Ω) |
|----------------------|--------------------|------------------------|--------------------|
| Bone tissue | 800–1500 | Tendon / Calcified fiber | 600–750 |
| Neural tissue | 400–550 | Muscle fiber | 300–400 |
| Fat | 200–300 | Nucleus pulposus | 120–250 |
| Body fluid | 50–100 | Internal cavity | Circuit disconnection |
**Electrode Disinfection Methods**:
1. Use high-temperature and high-pressure sterilization in a disinfection box for more than 2 hours.
2. Place in a fumigation box for 6 hours or longer.
3. The puncture needle is a single-use sterile package and should not be reused.
