Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] figure 1 As shown, the present invention realizes functions through four sub-systems: main control system, power control and feedback system, electrode identification and pre-control system, and target tissue dynamic identification and feedback system.

[0032] The main control system is electrically connected with the other three systems respectively, and is used for storing and computing electrode identification signals and target tissue identification signals, as well as command output and control.

[0033] The power control and feedback system is electrically connected to the external power supply, surgical electrodes, and the main control system, and is used to provide arbitrary power and waveform output to the surgical electrodes according to the instructions of the main control system, and to feed back the output results to the ...

Abstract

The invention discloses a dynamic output and control system for an electric knife power source. The dynamic output and control system is composed of four subsystems including the main control subsystem, the power control and feedback subsystem, the electrode identification and predictor control subsystem and the targeted tissue dynamic identification and feedback subsystem. Through work-shared cooperation and coordination between the four subsystems and three working circuits, compatibility of various electric knives is achieved, waste of resources is reduced, the precision and stability of power output of the electric knives are also improved at the same time, defects of a fixed power output mode are overcome, the risk of thermal damage to targeted tissue and the surgical difficulty for surgeons are reduced, the success rate of surgery is increased, the surgical time is shortened, and a high clinical application and popularization value is achieved.

Description

technical field [0001] The invention relates to a dynamic output and control system of an electric knife power source, which belongs to the technical field of medical equipment. Background technique [0002] The working goal of the electrosurgical system is to cut and coagulate blood accurately and quickly, with less tissue thermal damage. The working effect is related to the output frequency, waveform, and power of the electric knife, the composition, size, medium properties, blood concentration, and impedance of the target tissue, and the size, shape, area of ​​action, and mode of action of the knife head of the electric knife, as well as the operator's operation It is related to speed, method, skill, etc., that is, the working effect is closely related to the power source, target tissue, electric knife head and operator. The advanced electrosurgical system should create a closer connection among the four, and the dynamic synergy can exert the best surgical effect. [00...
