This study compared two helium plasma tools—the Renuvion handpiece and the TheraDep deposition device—both powered by the same Apyx Ultimate generator, to determine how their energy outputs and clinical applications differ.
Key Findings
-
Significant Power Reduction: While the Renuvion device delivers high power (5.6–8.2 W) for surgery, the TheraDep accessory reduces this to a much lower range (1.9–4.2 W).
-
Transformation of Function: The addition of the TheraDep accessory converts a high-energy surgical tool (used for cutting and coagulation) into a low-energy device suitable for plasma medicine.
-
Thermal Safety: Because of the lower energy output, the TheraDep device limits localized heating. It provides controlled coagulation but is incapable of cutting tissue, making it safer for delicate applications.
-
Different Plasma Chemistry: Optical analysis showed variations in ionized species between the two, likely caused by how each device draws in and interacts with the surrounding air.
Conclusion
The study demonstrates that by simply changing the handpiece accessory, clinicians can switch from aggressive surgical cutting to gentle plasma therapy using the same FDA-cleared power source. This opens new doors for targeted, localized plasma treatments without the risks associated with high-heat electrosurgery.
