Treatment by thermal ablation Ė The benchtop model
There are essentially two varieties of thermal ablator Ė a benchtop model and a battery-driven portable model. The benchtop model (also known as Semmís cold coagulator) runs on electricity and weighs around 3.5 Kg. The operation/ use of the instrument is quite simple and is very convenient.
The front panel of the machine has a switch to turn the machine on and off, a temperature adjustment knob to set the temperature, a temperature display, and a timer (optional). There is a handheld thermal probe with a metallic shaft and a heating plate at the tip. The diameter of the tip is 19 mm, which may be flat or with a small nipple at the center. The probe is connected to the front of the main unit with a cable.
