Helica Thermal Coagulator

System Overview

Helica Thermal coagulator for the treatment of Endometriosis.

Benefits of the Helica TC:

  • Extremely safe with a simple anaesthetic approach
  • Has a self seeking attraction to diseased tissue
  • Non ionised helium aids patient O2 levels
  • Complete control over the tissue depth
  • Simple to use compared to the commonly used laser device
  • Cost effective
  • Quick set up time
  • Uses across all clinical specialties

The Helica TC is simple to use, as compared to commonly used laser devices (eg CO2, KTP).

Complete control over tissue depth penetration is a prime benefit of using the Helica TC. Minimal tissue penetration is therefore readily feasible. In eradicating diseased tissue in the larynx, as little damage as possible to healthy tissue is crucial. Minimal penetration depth when using the Helica TC on the larynx will mean less laryngeal muscle tissue inflammation as a side effect. Ease of use of the Helica TC within the larynx allows for greater accuracy in treatment and again minimizes potential collateral tissue damage.

The beam of ionized helium from the Helica TC is attracted to the diseased tissue because of the lower resistance to the wet tissue.

The Helica TC is extremely safe to use, quick to set up and far less bulky than conventional laser equipment. Its use of non-ionised helium aids the level of O2 in the patient.

Use of the Helica TC involves a simple anaesthetic approach. On the other hand, laser use entails laser-protected endotracheal tubing and humidified gauze on the face, both of which extend anaesthetic and surgical set-up time.

Use of conventional laser equipment requires the operating surgeon to be a verified laser operator and all theatre staff to be wearing protective eye covering. Less finely controlled conventional laser equipment increases the possibility of collateral tissue damage while in use.
