Description

A plasma surgery system Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a plasma surgery system. Background Art

[0002] Low-temperature plasma technology is a relatively mature and thriving applied science. It has been widely used in both traditional and high-tech fields. In the early 21st century, low-temperature plasma radiofrequency was used in electrosurgery, and its various advantages gradually emerged. Compared with ordinary radiofrequency, plasma can perform operations such as cutting and ablation of tissues at a lower temperature (40-70°C) at a lower energy frequency (100KHz). Surgeons use plasma surgical equipment to perform specific functions during surgical procedures. For example, in cutting mode, the electrical energy generated by the surgical equipment is used through the surgical blade to remove the corresponding soft tissue, such as sinus tissue, tendons, ligaments, articular cartilage or synovial tissue. The main problems of existing plasma radiofrequency surgical systems are as follows: the host is prone to heat, which affects the life of the equipment; the working end of the transmitting electrode cannot be adaptively extended and retracted, which can easily increase tissue injury and reduce surgical comfort and safety.
