ABSTRACT

This article aims to introduce the progress, mechanism, advantage, disadvantage and application of cryoablation technique, as well as the most advanced instruments in the world nowadays, which have been clinically used for the treatment of cancer, and their operating principles and functions.The following are some of the state-of-the-art cryoablation instrumentsthe ArcticFront balloon catheter for the ablation of pulmonary vein(CryoCath Technologies Inc., Canada), the V-probe(Endocare Inc., U.S.A.), which can generate iceball of five different diameters by adjusting the slip-twisting position, the 1.47 mm diameter probe(Galil-medical Inc., Israel), the Cryo-s(Metrum-cryoflex Inc., Denmark), and cryosurgery-hyperthermia equipment and"nano frozen"technique(Liu Jing's Study Group).The prospect of cryoablation technique is also discussed in this paper.
