A research on using nitrogen liquid for cryoprobe in vietnam

Abstract

One of the methods of destroying the cancer cells is freezing these cells by cryo technique at a very low temperature. Firstly, a cryoprobe whose top is frozen is put into the cancer cells. When refrigerated rapidly, they will be dead or very weak and destroyed by the body’s resistance. After that, they will be eliminated by the body or removed by surgery. To freeze cryoprobe’s top, people use LPG (Liquefied Petroleum Gas) in low temperatures. So the important part of operating cryoprobe is how to arrange and use LPG for endothermic process from cancer cells.
This article analyzes and proposes using nitrogen liquid to freeze cryoprobe’s top in Vietnam.
