THERMAL EFFECTS ON TISSUE

The soft tissue coagulator uses a combination of helium gas and alternating current to deliver energy to tissue. Its main advantage over other equipment currently available for achieving coagulation and haemostasis is the use of very low power levels in laparoscopic mode.

The energy is delivered efficiently in a non-touch mode via the Helium gas, which is easier to ionise than Carbon Dioxide, Air and Argon. The physical effects are controlled by modifying the power to produce effects similar to those of the Argon Bean Coagulator.

At low power settings and with optimal Helium beam control techniques, thermal energy transmitted to surrounding tissues is minimised. Below 4W, spot helium beam temperature on the surface is below 100°C with cool down to 60°C in less than 2 seconds. Above 4W, spot Helium beam temperature on the surface can reach above 150°C with cool down to 60°C in less than 5 seconds. As such, targeted tissues can be fulgurated efficiently with minimal thermal injury to surrounding tissues.

OPTIMUM HELIUM BEAM CONTROL

Penetration depth is determined by power setting used and elapsed time of application. Low power setting and short time of application will result in penetration depth as low as 1 cell depth. For desired precision depth and least amount of heat transmission to surrounding tissues, apply Helium beam in continuous strokes - 'circular' or 'zig-zag' strokes are recommended. Egg white was used for the video demonstration

Zig-Zag Stroke

Application time is expected to be more than 1 second for power settings between 2W-4W, depending on tissue characteristics. Application time can be less than 1 second for power settings above 4W, when recommended optimum helium beam control methods are used.

Helium Gas Is Lighter Than Argon Gas Used In Argon Beam Coagulator

Helium is a light gas and can be ionised at power as low as 2W. Argon gas used in the Argon Beam Coagulator is heavy and will require higher power to ionise. As a result, Argon gas pressure and flow rates will be higher.
