The plasma surgical system has the following main features: Low temperature control: no charring of the wound surface and little damage to the surrounding tissues. Precise operation: the ablation effect is controlled on the surface of the target tissue, and the ionic action range is only 100 microns. Safety: The radiofrequency electric field is only limited to the bipolar region of the knife head; the working energy is precisely controlled at 3-4eV, which effectively avoids damage to the nerves. Efficient reduction: Controlled ablative plasma perforation achieves immediate and delayed tissue reduction. Minor trauma: small mucosal damage, less bleeding, less pain, faster recovery. Functionality: The surgeon can select different plasma knives, i.e., the appropriate energy level, to perform perforation, cutting, ablation and simultaneous hemostasis according to the needs of the procedure. Easy operation: the system does not need to be warmed up, and the operation only takes 10-15 minutes.
