A new concept for cryosurgery control is presented in this paper, a concept which has the potential to dramatically change the outcome of cryosurgery. Unlike other cryosurgery control techniques, which are based on controlling the thermal performance of the cryoprobe, this new concept is based on heating the treated tissue as a means of shaping the frozen region. The new controlling heater is termed a 'cryoheater'. The cryoheater is a complementary device to the cryoprobe and can work with any cryosurgery cooling technique. In the current pilot study, the new cryoheater is demonstrated in a gelatin solution and, using heat transfer simulations, it is studied in simulated cases of prostate cryosurgery. It is suggested that cryosurgery planning tools and optimization techniques must be developed before the concept of the cryoheater can be applied in its full capacity.
本文提出了一种用于冷冻手术控制的新概念，该概念有可能极大地改变冷冻手术的结果。与其他基于控制冷冻探针热性能的冷冻手术控制技术不同，这一新概念是基于对治疗组织进行加热以塑造冷冻区域。这种新型控制加热器被称为“冷冻加热器”。冷冻加热器是冷冻探针的辅助设备，可与任何冷冻手术冷却技术配合使用。在当前的初步研究中，新型冷冻加热器在明胶溶液中得到了展示，并通过传热模拟，在前列腺冷冻手术的模拟案例中对其进行了研究。研究表明，在冷冻加热器的概念能够充分应用之前，必须开发冷冻手术规划工具和优化技术。
