Abstract: A device for cryotherapy treatment of gastrointestinal lesions includes a cooling member that may be attached to a first tube for pressurizing cryogenic fluid through the tube and into the cooling member through nozzles located at the distal end of the first tube. A second tube may be attached to the cooling member for evacuating the cryogenic fluid from within the cooling member, following the fluid's expansion once it exits the first tube. The cryotherapy device may be attached to an endoscope such that the first tube may be passed through the endoscope's working channel, while the second tube may be passed along the endoscope's circumference. The cryotherapy device may further comprise securing means attached to the first tube, for securing the first tube to the endoscope's working channel, thus preventing free rotation of the cryotherapy device within the endoscope, relative to the rotation of the endoscope. In addition, the securing means assist in maintaining a constant and known location of the nozzles relative to the distal end of the endo scope.

Abstract translation: 用于冷冻治疗胃肠损伤的装置包括冷却构件，该冷却构件可以附接到第一管，用于通过管加压低温流体并通过位于第一管的远端的喷嘴进入冷却构件。 第二管可以附接到冷却构件，用于从冷却构件内部排出低温流体，一旦其离开第一管，流体膨胀。 冷冻治疗装置可以附接到内窥镜，使得第一管可以通过内窥镜的工作通道，而第二管可以沿着内窥镜的圆周通过。 冷冻治疗装置还可以包括附接到第一管的固定装置，用于将第一管固定到内窥镜的工作通道，从而防止冷冻治疗装置相对于内窥镜的旋转在内窥镜内的自由旋转。 此外，固定装置有助于保持喷嘴相对于内窥镜远端的恒定且已知的位置。
