- Ablate tissues by freezing
What is it
- Cryoablation is a process that uses extreme cold to destroy malignant tissue. Cryoablation is performed using hollow needles through which Argon gas is circulated. Cryoprobes are positioned adjacent to the target in such a way that the freezing process will destroy the diseased tissue.
How it works?
- Cryotherapy is the latest modality by which localized cancers/ tumors are destroyed by freezing the cells to minus 200° Celsius. In this procedure a Cryo probe/ needle is inserted into the tumor under imaging. This Cryoprobe is connected to the Cryotherapy equipment, which has an inlet for the cylinders of Argon and Helium gases.
- The Cryoprobe has a chamber in the distal end of the probe, into which Argon Gas is released at 6000 psi pressure. Due to the Joule-Thomson effect the released Argon gas cools the chamber to minus 200° Celsius. The surrounding tissue which has water molecules, creates an ice ball, which destroys the tumor. The Argon gas is returned to the atmosphere from the chamber through the Cryotherapy equipment.
