Problems solved by technology

[0004] However, the transmission cables are generally relatively long. During surgery, when the high-frequency high-voltage signal reaches the surgical electrode through a long transmission cable, the impedance will change, resulting in the inability to achieve a good impedance match with the human body. At the same time, the high-frequency In the case of impedance mismatch, the high-voltage signal will produce large energy loss and radiation interference, which will have a negative impact on the operation

Abstract

The invention discloses an electrosurgical system and a surgical electrode. A first high-frequency electric signal is generated and output through a high-frequency energy control device, and the firsthigh-frequency electric signal is transmitted to the surgical electrode through a transmission cable with preset impedance; and the surgical electrode carries out boosting processing on the first high-frequency electric signal to obtain a second high-frequency electric signal, and operation is carried out on human tissue. Therefore, energy loss and radiation interference of the electrosurgical operation system can be reduced, and impedance matching with a human body is more accurate.

Description

technical field [0001] The invention relates to the technical field of electrosurgery, in particular to an electrosurgery system and surgical electrodes. Background technique [0002] Electrosurgery is a surgical treatment method performed by the coagulation and cauterization effects of high-frequency current. The general effect on the skin is to conduct heat to the tissue, or to generate a thermal reaction in the tissue through an electric current. Electrosurgical methods commonly used in skin surgery are electrocoagulation and electrocutting, which are used in the same way as in general surgery, while electrocautery, electrodrying and electrocautery are used in combination with other treatments in dermatology. [0003] Electrosurgical systems generally include high-frequency energy control devices, transmission cables, and surgical electrodes. The existing technology is to generate a high-frequency and low-voltage signal through a high-frequency energy control device, an...
