D450V1 and D450V2 are the best in the class. They incorporate the latest technologies to give unmatched performance: flexibility for the surgeon to meet specific needs and utmost safety for the patient. The conventional surgical diathermy produces output which is highly dependent of tissue type. TTM (Tissue Type Monitoring) technology incorporates continuous monitoring of the tissue type using high-speed microcontroller and adjusts the output accordingly. The TTM technology guarantees reproducible cutting and coagulation quality - largely independent of cutting electrode, the cutting process and the tissue type. It also reduces smoke generation, tissue damage and necrosis.
