Cauterization is a medical technique of burning a part of a body to close-off or remove a part of it. High frequency radio waves are passed (around 2 MHz) through soft tissue to coagulate or remove it. In Haemorrhoids, this technique is successfully used to remove the swollen parts, whether external or internal. A hand piece with an active electrode is used by the surgeon to transmit the radio waves. They are focussed on the tissue by an antenna plate which is positioned behind the tissue.

The advantages are:

Minimum blood loss and pain for the patient.

It is shock proof.

Minimum heat and no charring which results in least tissue damage.

Pin point cutting capability.

Local anaesthesia is not required.
