    • PROBLEM TO BE SOLVED: To provide a safety device for a cryogenic medical instrument for preventing leakage into a patient's body when a gas leak occurs at a probe. SOLUTION: The safety device for the cryogenic medical instrument used in a cryogenic treatment to necrotize an affected area by repeating freezing and thawing of the affected area by alternately supplying a freezing gas and a thawing gas to the probe 1 which pierces the affected area comprises a sheath tube 2 for preventing the gas leakage into the body of the patient when the gas leak occurs at the probe 1, a gas leak detecting means 14 for detecting the gas leak, and a control means for halting the supply of the gas to the probe 1 by a gas leak signal detected by the gas leak detecting means 14 and ensures the safe cryogenic treatment since the sheath tube 2 prevents the gas leakage into the body of the patient when the gas starts leaking from the probe 1 during the cryogenic treatment.

    • PROBLEM TO BE SOLVED: To provide a probe for freezing treatment having sufficient freezing ability, restricted in the device cost and the running cost by not using high-pressure gas, and facilitated in operation by not using dry ice and liquid nitrogen. SOLUTION: A Peltier element module 5 is arranged between a soaking plate 8 at a first temperature end and a water-cooled jacket 9 at a second temperature end to generate a temperature difference. A cooling device 12 cools the water-cooled jacket 9, a control circuit 10 supplies power to the Peltier element module 5, and the heat is moved from the soaking plate 8 to the water-cooled jacket 9 to cool the soaking plate 8. A heat pipe 3 is inserted into a human body, and the heat inside the human body at a tip thereof is transmitted to the soaking plate 8 by the heat pipe 3 to freeze the diseased part. The heat pipe 3 and an outer pipe 2 are insulated by a vacuum space. COPYRIGHT: (C)2008,JPO&INPIT
    • 要解决的问题:为了提供具有足够冷冻能力的冷冻处理用探针,通过不使用高压气体来限制器件成本和运行成本,并且通过不使用干冰和液氮来促进操作。 解决方案:珀耳帖元件模块5布置在第一温度端的均热板8和第二温度端的水冷套管9之间以产生温度差。 冷却装置12对水冷套9进行冷却,控制电路10向珀耳帖元件模块5供给电力,并且从均热板8向水冷套9移动热量以冷却均热板8。 将热管3插入人体内,将其顶端的人体内部的热量通过热管3传递到均热板8,以冻结患部。 热管3和外管2被真空空间绝缘。 版权所有(C)2008,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a treatment device which is used for cryotherapy and shows various effective directional characteristics in the depth and lateral directions. SOLUTION: The treatment device 100 comprises a metal tube 1 and a freezing terminal 2 inserted into the metal tube 1 for the attachment. The freezing terminal 2 has a thermal exchange feature between freezing and thawing at the distal end. The treatment device 100 has a helium gas supply source 3 and an argon gas supply source 4 for the freezing and thawing, and is equipped with a switching part 5 for supplying the gas by alternately switching. The treatment device 100 is equipped with a protruding part 20 protruding outward in the circumference of the distal end of the metal tube 1. The protruding part 20 gives thermal directivity to the outside. COPYRIGHT: (C)2007,JPO&INPIT
