Embodiment 1

[0023] Example 1, such as figure 2 An example of using a Zener diode as a two-port voltage regulator is given. The anode of the Zener diode is connected to the cut outer electrode. During online measurement, when the power source flows positive current into the negative pole of the Zener diode, measure its steady voltage value, and after quantification, the model code of the cutting head can be determined. When the power source flows negative current into the negative pole of the Zener diode, the measured voltage value is the forward voltage drop value of the diode.

Embodiment 2

[0024] Example 2, such as image 3 Gives another example of using a Zener diode as a two-port voltage regulator, and the negative pole of the Zener diode is connected to the cutting external electrode. During online measurement, when the power source flows negative current into the positive pole of the Zener diode, measure its voltage stabilization value, and after quantification, the model code of the cutting head can be determined. When the power source flows positive current into the negative pole of the Zener diode, the measured voltage value is the forward voltage drop value of the diode.

Embodiment 3

[0025] Example 3 as Figure 4 An example of using two Zener diodes in reverse series as a two-port voltage stabilizer, the negative poles of the two Zener diodes are connected together, and the positive pole of one Zener diode is connected with the cutting external electrode is given. During online measurement, when the power source flows positive current into the marked electrode, measure the D1 steady voltage value plus the forward voltage drop of D2; when the power source flows negative current into the marked electrode 8, measure the D2 steady voltage value plus D1’s positive pressure drop. According to the measured two sets of voltage values, the model code can be determined after quantification. Since there are two sets of voltage values, more coding combinations can be formed.

Description

Technical field [0001] The invention relates to a circuit marking method, in particular to a circuit marking method of a medical bipolar plasma cutting head. Background technique [0002] The bipolar plasma cutting head is a surgical instrument used for electrosurgical treatment of patients with a bipolar high-frequency power source, such as the treatment of benign prostatic hyperplasia and other diseases. Two modes of tissue action are produced by adjusting the power of the high-frequency power source. The first mode will generate an ionized plasma halo in the active area of ​​the tissue treatment electrode, and the tissue entering the high-energy plasma halo will be vaporized instantly, and then rinsed with irrigating fluid. Lose. In the second mode, tissue temperature can be raised rapidly, predictably, and in a controlled manner to melt tissue or seal blood vessels. There are many types of cutting heads for different purposes. [0003] Since the source acting on the b...
