The invention relates to a high-frequency electrotome operation control method and device and a high-frequency electrotome system.When a high-frequency electrotome operates, least square fitting can be conducted through output electrical parameters of the electrotome in the working state of the high-frequency electrotome, and an optimal voltage curve is obtained; and then the output current parameters of the cutter are obtained and matched with the optimal voltage curve for analysis, dynamic following and adjustment are achieved when the frequency of the cutter changes, and therefore the cutter is kept in a running state. According to the scheme, the least square method is adopted for fitting the voltage curve, rapid and high-precision frequency tracking and adjustment are achieved, the implementation speed of heating maintaining work can be effectively increased, and then rapid and complete blood vessel closing and hemostasis operation can be achieved within 3-4 seconds.
Description
technical field [0001] The present application relates to the technical field of electrosurgical equipment, in particular to a high-frequency electrosurgical operation control method and device and a high-frequency electrosurgical system. Background technique [0002] High Frequency Electrosurgical Equipment is an electrosurgical instrument that replaces a mechanical scalpel for tissue cutting. It heats the tissue when it comes into contact with the body through the high-frequency and high-voltage current generated by the effective electrode tip, so as to realize the healing of the body tissue. Separation and coagulation, so as to achieve the purpose of cutting and hemostasis. According to different working modes, it can be divided into high-frequency monopolar electrosurgical unit and high-frequency bipolar electrosurgical unit. [0003] At present, the 500KHZ high-frequency bipolar electric knife is a relatively common and advanced equipment for blood vessel closure surge...
