The Thermocoagulator is a handheld device used to treat human tissue lesions. The unit is designed based on the World Health Organization’s guidelines and recommendations for fighting the growing epidemic of cervical cancer. It is a type B thermal coagulator which is a compact, portable, battery-powered mobile device which can be used in hospital and non-hospital rural healthcare locations. It is reusable and provided non-sterile and designed to perform low-power destruction of human pre-cancer cervical or other tissue with high temperatures by tissue contact with a heated probe tip.

Key Features

Heated Probe Tip
Contains a heating element, which is heated to 100°C (212°F) on the default setting for the destruction of human tissue. The probe tip should only be applied to tissue, which is intended to be ablated. The TC probe shaft is not intended to deliver heat. The probe shaft and sidewall tip has a maximum temperature of 43°C (109°F). Contact with the probe shaft should be avoided during the procedure.

Automated procedure timing with visual and audible indicators – no watch or clock required. Can be set to 20, 30, 40, or 60 seconds and 80, 90, 100, or 120°C.

Exchangeable Probes
Heat quickly (5-8 seconds) that can be autoclaved for sterilization.

Lightweight with no tether wires or cables required to connect probe to device and no external power supply required for treatment.

    “The procedure went well. The 19 mm probe works well and I used it for 2-3 application as the cervix was bulky. The heating time, timer, etc. works well and cervix appears exactly how it appears after treatment with cold coagulation.”

    Smyta Joshi, MD Hirabai Hospital Pune, India

    “I took delivery of a package for our Cervical Cancer Prevention and Training Centre, Battor. Really light devices! Cervical cancer screening and treatment will never be the same again in Battor/Ghana! Simplified! Mobile services becoming more and more available. No need to carry large gas cylinders.”

    Dr. Kofi Effah , Cervical Cancer Prevention and Training Centre, Catholic Hospital, Battor, Ghana

    “Thermal coagulator is doing so great and it’s a nice machine so to say and very simple to use and assemble. We have both WISAP, the original table top and handheld. But I love the TC unit because of its simplicity to use. I am a national trainer for cervical cancer screening and last month we had a training, where we had participant from 25 out of 28 district in Malawi. In treatment of pre-cancer lesion we oriented all participants on how to use thermal coagulator so that when they are choosing method for treatment they have options. We use both TC (Thermocoagulator) and WISAP (Cold Coagulator), one comment that come out was the TC Unit is very simple to use and not complicated. And many participants really liked it. About the New WISAP. They don’t have a flat probe which makes your probes good for more options during treatment.”

    Beatrice Kabota, Nkhoma CCAP Hospital, Lilongwe Malawi


    How do I know that thermocoagulation™ is as effective as cryogenic therapy?

    Literature studies have validated that the outcome clinical efficacy is as good or better with thermocoagulation™ as compared to freezing. Refer to Duncan’s studies as shown in Dolman’s meta-analysis in the website educational section. The Liger thermocoagulator™ uses the latest state-of-the-art technology to reach and maintain the treatment tip accurately at temperature within 0.2°C.

    What is cold coagulation as compared to thermocoagulation™?
    They are the same, cold coagulation is a misnomer as it uses heat to cause tissue destruction.
    How long and at what temperature should pre-cancerous cervical lesions be treated?
    The time of 20 seconds and 100°C is the standard used by Duncan in his original work (see references). The treatment time is shown by each blue LED turning off as ¼ of the time is up, and also an audio sound given). When all blue LED’s are off the treatment cycle is completed.
    How many treatments can I expect with a full battery charge?
    Standard treatment of 20 seconds at 100°C has been tested on 50 applications before the low battery charge comes on. On body temperature cervical tissue, more cycles could be experienced. If more than one site on the same patient’s cervix is performed, this needs to be taken into account. When the low battery LED indicator comes on, there still is sufficient energy left in the battery to finish that treatment.
    How do I clean the Probe?

    The full high-level sterilization is given in the IFU that was sent with each unit on page 5 column 2. Many users follow the method below for cleaning and Hi-level disinfection of the probes:

    Place the silicon cap firmly over the connector end. Clean any debris off the probe with mild detergent and water using a soft cloth or soft brush, then rinse in clean water.
    Place the probes upright in a cup (approximately 5- 6” deep) of ~2.5% gluteraldeyde (Cydex) for 20-60 minutes (some sites use a 0.5% Chlorine solution-Chlorox).
    This allows the connector end not to be immersed in solution which is not necessary as the connector end is not inserted into the patient nor contacts the patient and need not be sterilized.
    Some users apply a heat cycle of the device to assure that the heated end has reached a sterilization temperature but this is unnecessary and regulatory agencies have not approved this procedure for sterilization. It certainly does sterilize the tip as all viral proteins are denatured above 60’C.
    Rinse the probe end (not the connector end with the silicone cap) with clean, non-contaminated water, thoroughly dry the probe in air.
    Wrap in clean material to keep it from being contaminated before next use.
    The handle can, if needed, be wiped clean with a cloth dampen with a small amount of alcohol.

    Is there any difference between the two batteries in the pack?
    No, they are identical, the protective boot on the base of the battery can be moved to either battery. The batteries can be recharged in a couple of hours.
    What is the depth of tissue destruction for a 20 second/100°C cycle?
    Studies in Chicken breast show a depth just over 5 mm. Duncan’s studies showed this setting was adequate and the overlapping treatment to cover the total lesions was good.
    How does the thermocoagulator™ compare to cryotherapy?

    The thermocoagulator™ is quicker, easier and simpler to use. The thermocoagulator™ procedure is approximately 20 seconds per treatment as compared to cryotherapy which requires 11 minutes per treatment. The thermocoagulator™ has easy to use rechargeable batteries that use minimal energy, whereas cryogenic requires costly replacement gas cylinders.

    What's the expected lifespan of the batteries?
    The batteries are expected to last more than 2 years. Testing data has shown NO degradation of battery life even with heavy use
    over a two year period. This included 1300 heating cycles on the two batteries with a recharge on the battery every 30 cycles.
