热–力耦合作用下的冷冻消融手术模拟研究
A Simulation Study of Cryoablation Surgery under the Effect of Heat-Force Coupling
摘要: 本文通过COMSOL软件建立了三维肝肿瘤模型,研究了热–力耦合作用下的冷冻消融手术过程。结果表明,在线弹性模型为前提的情况下,只有探针周围极小区域的应力超过了屈服应力,与不考虑力场的数值模拟相比,该模型中组织相变导致的变形对冷冻范围产生了约10%的影响。
Abstract: In this paper, a three-dimensional liver tumor model was established by COMSOL software to study the cryoablation procedure under thermal-force coupling. The results show that only a very small area around the probe exceeds the yield stress under the premise of the in-line elastic model, and the deformation due to the tissue phase change in this model exerts about 10% influence on the cryoablation extent compared with the numerical simulation without considering the force field.
