本文提出了一个新的概念，冷冻手术控制，一个概念，有可能大大改变冷冻手术的结果。与基于控制冷冻探针的热性能的其他冷冻手术控制技术不同，该新概念基于加热被治疗的组织作为使冷冻区域成形的手段。新的控制加热器被称为“低温加热器”。冷冻加热器是冷冻探针的补充装置，可以与任何冷冻手术冷却技术一起工作。在目前的试点研究中，新的冷冻加热器在明胶溶液中进行了演示，并使用热传递模拟，在前列腺冷冻手术的模拟病例中进行了研究。有人建议，冷冻手术规划工具和优化技术必须开发的概念之前，低温加热器可以应用在其全部容量。
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.
