The RF current generates energy between the two electrodes of the cutter head and excites the conductive medium (physiological saline or body fluid) in the front section to generate plasma. The high-energy particles in the plasma can decompose the molecular bonds in the tissue, so that Vaporize, coagulate, ablate, and cut tissue under the premise of contact with tissue.
Coagulation under intervertebral foramen, decompression of nucleus pulposus discectomy, ablation of nucleus pulposus.
Plasma Electrode Endoscope Electrode
The electrode head is freely retractable, making it easier to reach the lesion and more convenient for intraoperative manipulation.
Cervical Spine Plasma Electrodes
Lumbar Spine Plasma Electrodes
High efficiency of soft tissue removal
The 90°design of the electrode head integrates ablation and haemostasis, and the suction function clears tissue debris in time for a clearer surgical view.
High safety Low nerve irritation
The electrode head is designed with a 30°bend angle for minimal power to ablate soft tissue and stop bleeding.

Electrodes are specifically designed for thyroid ablation and lymph node ablation. – Theyhave easy penetration and maneuverability within the tissue
When an rf current is applied to a planar coil, an oscillating magnetic field (B-field) is created both above and below it. This generates a primarily azimuthal rf electric field. Inside the vacuum chamber, this E-field starts an electron avalanche which creates the plasma.
Radiofrequency plasmas (rf plasmas) are formed in a flow of gas by an externally applied radio frequency field. … The coupling efficiency is the ratio of power accepted by the plasma to the incident power, i.e. the output of the oscillator. Reflected power is the power reflected back to the oscillator.
