R-2000B series RF fuser is developed and produced by Beijing Beiqi Medical Technology Co., Ltd. There are thousands of hospital users in China. The departments of service include: pain department, neurosurgery, rehabilitation department and orthopedics department. Another consumables: RF electrodes for cervical and lumbar spine surgery, disposable RF trocars.
Measure tape is a measuring Tool which is commonly used in our daily life, when building, decorating and making wooden furniture, we often use steel tape measures. In fact, besides steel tape measure, there are also other types of tape measures, such as fiberglass tape measure, laser tape measure and ground fiber tape measure.
Beijing Beiqi R-2000B (Chinese) RF Fuser
Operating procedures:
1. Connect the negative electrode to the negative electrode and the other end to the machine. Attach the negative electrode to the patient. The closer the negative electrode is to the needle, the better. Connect the positive wire to the machine and connect it to the machine. On the electrode. Insert the electrode needle into the previously inserted trocar.
2, boot, after hearing a piece of music, wait a moment, the value of the impedance will be displayed.
3. After confirming that the impedance is no problem, press the “stimulus†button.
4, a quick way to stimulate electricity: press the "stimulus" button. The voltage on the screen of electrical stimulation will appear: 1.00V, frequency: 100HZ. At this time, press “F1†button, it will appear: voltage: 000V, frequency: 2HZ, press “Start†button, it is doing exercise electrical stimulation, then Turn the knob, the voltage will be automatically added, up to 2.0V, when the patient is added to 2.0V, there is no muscle jumping, it is not on the motor nerve, it is safe, it can be. This is the electrical stimulation of the motor nerves.
Press "Stop" after the exercise motor stimulation is completed. Press the “F1†button again, it will appear: voltage 000V, frequency: 50HZ, then press the “start†button, it will do the electrical stimulation of the sensory nerve, then turn the knob, the voltage will be added automatically, up to 2.0 V, when added to 2.0V, the patient does not feel overpowered, it is not on the sensory nerve, it is safe, it can be. This is the electrical stimulation of the sensory nerves. The patient has nothing to reflect. It is proved that the needle tip of the puncture needle is not on the sensory and motor nerves.
5, a quick way to heat coagulation: press "stop" after no problem with electrical stimulation. Press the “Hot Curd†button again, the screen will appear 40 degrees, 60 seconds. At this time, rotate the knob (the rotary button is rotated when the step button indicator is lit, the increment is 0.5 degree, and when the step button indicator is not lit, the rotary button is 5) The degree is increased. The temperature will be once long. When you rotate to the temperature you want to set, press the “Start†button to start the heat setting. Press "Stop" to stop at any time.
6, the temperature of the treatment of disc herniation:
The temperature is from 60 degrees to one minute, 70 degrees to one minute, 80 degrees to one minute, 90 degrees to one minute, and 95 degrees to three to five minutes. During the treatment, the patient has fever and rise in the place where the temperature is set before the pain. It feels normal. As long as the patient can bear it, it will not damage the nerves. If it can't bear it, put the electrode into the middle of the intervertebral disc.
7, electrical stimulation of trigeminal neuralgia: the voltage of the sensory nerve electrical stimulation is 0 -0.5V, (from 0 on the electrical stimulation, rotating the knob, the highest rose to 0. 5V. The frequency is 50HZ. Do exercise motor nerve stimulation The voltage is 0 - 0.5 V. The frequency is 2HZ.
The temperature at the time of heat setting starts from 50. 60 degrees, 65 degrees, 70 degrees, 80 degrees each for three minutes (80 degrees is the highest temperature).
If the device has an alarm during the operation, a digital code will appear on the screen of the device. In the manual, you can find out what the problem is and how to solve it. If there is any error in the above settings, the actual situation will be determined.
RF thermocoagulation features:
- Electrical impedance test
Depending on the impedance values ​​of the different tissues (the table below is for reference only), the doctor can determine whether the position of the needle is at the position of the surgical target by measuring the impedance. The impedance reference values ​​are as follows:
organization
Impedance (Ω)
organization
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 method:
1. Put in high temperature and high pressure disinfection in the disinfection box (more than 2 hours)
2, put in a fumigation box fumigation (6 hours or more)
3. The puncture needle is a disposable aseptic package that does not require disinfection and must be used at one time.
