Abstract

The invention discloses an electrosurgical device and a control method thereof. The electrosurgical device comprises a biological tissue electrical signal collector, a controller and an air flow dutyratio adjusting unit, wherein the biological tissue electrical signal collector is arranged at the front end of an electrode; the controller is connected with the biological tissue electrical signal collector, acquires signals collected by the biological tissue electrical signal collector and determines whether the signals are within a preset interval corresponding to optimal therapeutic effects;when the biological tissue electrical signals monitored by the controller are smaller than or equal to the minimum value of the preset interval, the controller reduces the duty ratio of air flow, andwhen the collected biological tissue electrical signals are greater than or equal to the maximum value of the preset interval, the controller closes air flow outputting. By adjusting the duty ratio ofargon flow, the electrosurgical device achieves control over output energy, thereby reducing consumption of argon, saving control over voltage, current and power, simplifying control processes and improving control reliability and safety.

Description

technical field [0001] The invention relates to the technical field of electrosurgical equipment, in particular to an electrosurgical equipment and a control method thereof. Background technique [0002] The basic function of APC (Argon plasma coagulation, argon plasma coagulation) blood coagulation is to blow away the local hemorrhage and reveal the blood vessels with the jet flow of inert gas (such as argon), and the electrode stimulates the discharge to complete the argon ionization, and conducts high-frequency current to the tissue It produces thermal effect, so as to achieve the therapeutic effect of coagulation or tissue inactivation. It is most suitable for wound bleeding of sensitive tissues and coagulation and inactivation of tissue in small blood vessels. [0003] When using APC for hemostasis, the key point of "non-contact" is particularly emphasized. Because APC must first ionize argon gas for hemostasis, it should be close to the tissue to stimulate argon gas io...
