Abstract

The embodiment of the invention provides an electrosurgical generator, an electrosurgical system and a control method of the electrosurgical system. The method comprises the steps that after it is determined that two electrodes of a tool effectively clamp tissue, multiple sub-processes are executed in sequence, and each sub-process comprises a state judgment stage and a tissue fusion stage; wherein at least one control parameter and at least one end parameter of the current sub-process are determined according to at least one impedance parameter and at least one time parameter of the tissue in the state judgment stage of each sub-process; in the tissue fusion stage of each sub-process, energy is output to the tissue according to at least one control parameter of the current sub-process, and whether the current sub-process is ended or not is determined according to at least one ending parameter of the current sub-process. Therefore, according to the technical scheme provided by the embodiment of the invention, the tissue closing process can be adaptively controlled, the energy output to the tissue is dynamically and accurately controlled according to the closing state of the tissue, and the success rate of tissue closing and the bursting pressure of the tissue are improved.

Description

technical field [0001] The present application relates to the technical field of surgical instruments, and in particular, to an electrosurgical generator, an electrosurgical system and a control method thereof. Background technique [0002] An electrosurgical system (eg, a high-frequency electrosurgical system) includes an electrosurgical generator and a cutter connected to it. When applied to monopolar surgery, the electrosurgical system also includes a return electrode. The electrosurgical generator applies energy to the target tissue site through the tool to achieve the effect of electric cutting, coagulation or tissue closure. In monopolar surgery, high-frequency current is applied to the tissue site through the monopolar cutter, and then returned to the generator through the body and a return electrode attached to the surface of the body; in bipolar surgery, the high-frequency current is passed through the two electrodes of the cutter and The tissue clamped between the...
