摘要： PROBLEM TO BE SOLVED: To provide a cryogenic medical instrument in which it is prevented that a probe jumps out of an end of a sheath tube or high pressure gas jets into a subject when gas leakage occurs inside the sheath tube. SOLUTION: The cryogenic medical instrument is used for cryotherapy for necrotizing an affected part by supplying a probe 1 inserted in the sheath tube 2 punctured into the affected part with freezing gas and thawing gas by turns and repeating freezing and thawing of the affected parts. An end part of the sheath tube is provided with a coming-off stopping means 3 for preventing the probe from jumping out of the tip of the sheath tube by high pressure gas due to gas leakage occurred in the sheath tube. When gas leakage occurs inside the sheath tube for some reason during cryotherapy, the coming-off stopping means stops the probe from jumping out of the sheath tube to the affected part side by high pressure gas, so that safety of the cryotherapy is improved.

摘要翻译：要解决的问题：提供一种低温医疗器械，其中当护套管内发生气体泄漏时，可以防止探针从护套管的一端或高压气体射流向受试者跳出。
解决方案：低温医疗器械用于冷冻治疗受影响部位，通过将插入鞘管2中的探针1通过将冷冻气体和冻融气体循环穿刺入受影响部位，并重复受影响的患者的冻融部分。护套管的端部设置有脱离停止装置3，用于防止由于鞘管中发生气体泄漏而使探针从鞘管的尖端高压气体跳出。在冷冻治疗期间，由于某些原因在鞘管内发生气体泄漏时，脱落停止装置通过高压气体停止探针从鞘管跳出到受影响的部位，从而提高了冷冻治疗的安全性。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a medical instrument that effectively freezes or thaws an affected area. SOLUTION: This cryogenic medical instrument supplies a freezing gas and a thawing gas alternately to a probe 1 pierced into an affected area and is used in cryotherapy for necrotizing the affected area through repeated freezing and thawing. The cryogenic medical instrument has a heat transmission means 3 that expands by hydroscopic pressure, and carries out cryotherapy of the affected area by circulating the freezing gas and the thawing gas alternately through the heat transmission means 3. Because a volume and heat transmission area of the distal end of the probe 1 increases remarkably due the heat transmission means 3, the affected area is frozen and thawed effectively by the freezing gas and the thawing gas. With such a configuration, the affected area is necrotized in a short time, so that treatment time of the cryotherapy is greatly reduced together with burden imposed on a patient alleviated.

摘要翻译：要解决的问题：提供有效冻结或解冻受影响地区的医疗器械。解决方案：这种低温医疗器械交替地将冷冻气体和解冻气体提供给刺穿到受影响区域的探针1，并且用于冷冻治疗以通过反复冻融来坏死受影响的区域。低温医疗器械具有通过吸水压力而膨胀的热传递装置3，并且通过使传热装置3交替地循环冷冻气体和解冻气体来进行受影响区域的冷冻治疗。因为体积和热传递面积探头1的远端由于传热装置3而显着增加，因此，通过冷冻气体和解冻气体有效地使受影响区域被冷冻融化。通过这样的配置，在短时间内对受影响区域进行坏死，使冷冻治疗的治疗时间大大降低，同时减轻患者的负担。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To determine a freezing period and thawing period depending of the size of a therapy region, related to a therapy device used for cryotherapy and a cryotherapy planning device therefor. SOLUTION: A cryotherapy device includes a gas supply/exhaust system (100), a control system (200) therefor, and a freezing probe system (300). The gas supply/exhaust system (100) supplies a freezing gas and a thawing gas to a probe (60) of the freezing probe system (300) to freeze and thaw the therapy region near the end of the probe (60) by the Joule-Thomson effect. The control system (200) controls the gas supply/exhaust system (100) and creates therapy plan data for the control. The therapy plan data include a freezing and thawing sequence to determine the freezing period and thawing period. The computer in the control system (200) determines the sequence. The sequence is determined depending on the therapy size of the lesion according to the freezing and thawing characteristics of the tissue. COPYRIGHT: (C)2010,JPO&INPIT
