Thermo‐mechanical analysis of tumor‐tissue during cryosurgery: A numerical study

For decades, many techniques have been developed for curing cancer. Cryosurgery is one of such processes destroying tumors by inserting a cryoprobe into the target region which connected to cryogenic mechanism. Presently, this technique used only simple tumors. Hence, work aims trigger toward large-sized internal The main objectives are (1) identify mechanical and thermal behavior tumor tissue conducting parametric study, (2) analyze pain sensation during process (3) constraints surgery technique. whole study was done using COMSOL Multiphysics™ software. A 3-D model has presented, considering all properties be function temperature. Also, phase transformation bio-liquid ice considered in study. Results showed temperature stress distributions both surrounding healthy under different operating conditions. Heat transfer thermal-stress increased with increase probe diameter decrease size reached steady state at around 50 min. results gave an idea about time operation, experience effect cryosurgery on tissue. Treatment becomes simpler as moves out threshold treatment period predicted min, after patients could expect severe pain. This might help researchers surgeons improving understanding along its limitations.
