Bipolar cutting electrosurgical unit SPK100-2

coagulationbipolar coagulationcutting

Working principle
The plasma surgical device uses an RF field of approximately 100 kHz to excite the conductive saline irrigant around the electrode, forming a plasma layer about 100 μm thick. The plasma contains numerous charged particles that deliver enough energy to break molecular bonds in the target tissue, causing rapid decomposition at relatively low temperatures into low‑molecular‑weight molecules and atoms, thereby enabling cutting and coagulation.

Advantages

• Bipolar design: no current path through the patient, avoiding high‑frequency leakage currents.
• Uses physiological saline as the working medium, avoiding the risk of water intoxication.
• Reduces postoperative collateral damage; wound coagulation and sloughing are minimized, reducing urinary irritative symptoms and shortening recovery time.
• Main unit features automatic electrode recognition and automatically sets the corresponding power stage, reducing user error and simplifying the procedure.
