Coagulation electrosurgical unit SPK200

saline cuttingsaline coagulationcutting

Working principle
The plasma surgical device generates a thin saline plasma layer (~100 μm) around the electrode by a 100 kHz radiofrequency field. Charged particles in the plasma provide energy that breaks molecular bonds in target tissue, enabling tissue ablation and coagulation at relatively low temperatures.

Advantages

• Low-temperature operation (40°C–70°C) reduces thermal penetration and limits damage to surrounding tissue
• Multiple cutting modes to meet different clinical requirements
• True low-temperature cutting without tissue charring; produces smooth wound surfaces
• Uses physiological saline as the working medium, avoiding intraoperative water intoxication
• Interchangeable electrodes/tips available to suit various hysteroscopic procedures
