Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and more particularly to a plasma electrode for treating ear diseases. Background Art

[0002] The basic principle of low-temperature plasma surgical electrodes is to use the energy generated by the plasma generator to form a highly concentrated plasma layer between the plasma surgical electrode and the tissue. The plasma in the thin layer is accelerated by the electric field and has enough energy to crush the organic molecular chains in the tissue, decomposing the tissue into simple molecules, atoms or low molecular weight gases, thereby achieving the function of ablation and cutting. Since the current does not flow directly through the tissue, the tissue generates very little heat, so the treatment temperature is low (40-70°C), which can maintain the activity of cells. At the same time, due to the insulating effect of plasma and the thermal effect of current, blood vessels can be quickly contracted and coagulated, achieving the function of intraoperative hemostasis.

[0003] Among the common ear diseases, secretory otitis media and middle ear infection are mainly caused by bacterial infection, such as Pseudomonas aeruginosa. The traditional treatment method requires applying sterilizing agents to the ear. Severe cases require surgery to scrape the wound and sterilize it, but the operation is very inconvenient. Low-temperature plasma radiofrequency ablation can quickly sterilize the ear, but the electrode blade of plasma surgery needs to be replaced frequently, and the common electrode blade needs to be connected to the circuit when it is replaced, which is not convenient. Based on the above problems, we provide a plasma electrode for treating ear diseases. Summary of the invention
