Products /NuTouch® RF
The high efficiency NUTOUCH Ablator is the first to address the efficiency/power differential with its proprietary NUTOUCH Advanced Power Technology (APT).
The dramatic increase in efficiency allows the NUTOUCH Arthroscopy Ablator to operate at lower power levels than comparable ablators, achieving aggressive ablation quickly with reduced potential for thermal injury to the patient.
NUTOUCH RF ABLATOR–Power
- Unique Wedge Shape: Distal end configuration provides improved access and allows for tissue resection as well as bulk vaporization.
- Patented Power Profile: High-efficiency electrode construction, part of NUTOUCH Advanced Power Technology (APT), provides aggressive ablation at lower power levels than other bipolar ablators.
- No dedicated radio frequency (RF) generator is required. Compatible with most commercially available multi-purpose generators.
- Integrated aspiration available on 3.3mm probes,
providing a clear field of view while minimizing energy loss – another feature of Velocity’s APT technology.
- Bipolar tip design eliminates the need for the patient pad.
NUTOUCH™ Bipolar RF Ablators for arthroscopy use radio frequency power to generate arcing through bubbles formed between an active electrode and tissue with the tissue being vaporized by the arcing. These devices provide for the resection and ablation (bulk vaporization) of soft tissue as well as the coagulation of blood vessels. To date, bipolar ablation devices have required dedicated generators that produce power levels well beyond the capability of most standard general purpose generators. High power levels are
needed to “ignite” the ablators due to their inefficient design. Unfortunately, these high power levels may cause a significant rise in intraarticular saline temperature with an associated increase in the likelihood of thermal injury. Additionally, when using some of these devices, arcing (sparking) may occur between the active electrode and the return electrode due to the high power required for the forming of bubbles at the active electrode and the initiation of an ablative discharge.
Channels trap saline and heat to form bubbles allowing electrode to directly touch tissue while energizing
Sharp ridge edges act as energy directors and improve electron flow
Unique Wedge Shape: Distal end configuration provides improved access and allows for tissue resection as well as bulk vaporization.
Importantly, the power to the NUTOUCH RF Ablator is limited to a lower level if the appropriate tissue interface is not present and the probe is not firing. This is in contrast to other RF ablation systems which dramatically increase power when the probe is in this “pre-ablation” mode and is attempting to ignite. When energized but not firing, as may happen on a bony surface, other systems supply the probe with very high power levels which may increase the likelihood of thermal injury. The NUTOUCH ablators with their reduced power in the pre-ablation mode cause less temperature rise.
The NUTOUCH bipolar ablators connect to the monopolar active and return receptacles of the generator. The return electrode on the device replaces the return pad typically used with other devices.
Connect active electrode cable to monopolar foot control adaptor in Foot Control receptacle on the generator front panel.
Connect Return cable to Return receptacle on the front panel of the generator.
The ablator is controlled by the generator foot pedal. Depress CUT (yellow) pedal for ablation or COAG (blue) pedal for coagulation.
