The Smith & Nephew ELECTROTHERMAL◊ ARTHROSCOPY SYSTEM (EAS◊) is the only system to automatically deliver optimal therapeutic temperature for collagen modification in both cartilage and ligamentous soft tissue. All TAC probes measure actual tissue temperature 50 times per second. This provides direct thermal feedback to the Smith & Nephew VULCAN◊ Generator where immediate adjustment of energy output compensates for operative variables such as irrigation flow and treatment speed. When used in the shoulder, knee, hip or small joints, the result is a consistent, reproducible thermal effect.
- Wide range of probe styles that optimize joint access and tissue effect
- Malleable probe shafts reduce inventory requirements
- Integrated cable eliminates cable sterilization issues and enhances operating room efficiency
- Autoprobe generator recognition simplifies setup and use
- In ligamentous soft tissue RF energy provides a dual heating effect of molecular oscillation and heat conduction. The defined temperature range of 65° to 75° C was determined as optimal to stimulate collagen contraction. 1
- When treating articular cartilage, direct thermal feedback with automatic power control may significantly reduce thermal penetration depths. The advanced design of the TAC-C probes coupled with the specific articular cartilage temperature control program, has been shown to reduce thermal injury depth by as much as 68% when compared to bipolar ablation probes.2, 3, 4
