Tools of the trade: AcuSect


by Dr John Wells, Simply Beautiful Smiles, Penrith, NSW

The AcuSect is similar to an electrosurge in that it coagulates as it cuts. Instead of a heated wire, it uses radio waves at a frequency of four megahertz with resistance caused by the tissue. The heat is direct at the site.

What’s good about it

The AcuSect works much better than an electrosurge and is my go-to equipment for soft tissue trimming. I own two of these units—one in each of my surgeries.

It uses radio-wave energy and is very low heat compared to an electrosurge. It provides precision cutting and simultaneous coagulation with minimal lateral damage to any other tissue. There’s better and faster healing than with a conventional electrosurge.

The electrodes are malleable and can be bent to any angle. The electrodes also come in a variety of sizes—from as thin as a human hair to something that resembles a scalpel blade. It also includes unusual shapes like little balls and right angle cuts.

I do a lot of flap surgery with the AcuSect and there is minimal bleeding, fast healing and virtually no scarring. It also works perfectly well in a liquid medium whereas electrosurges are a bit hit and miss if any blood or saliva is present.

There’s no damage when used around an implant because there’s such low heat. I use it routinely for exposure, healing abutments and screws for second-stage surgery.

The electrodes are passive and all the energy is expended in the tissue. This means it’s safe to use with patients who have pacemakers.

What’s not so good

The AcuSect is such an efficient cutter that there isn’t much tactile feedback. The electrodes are so small and the cut is so precise that you need to be very deliberate with your cutting.
