Abstract

The invention provides a cryotherapy adhesion device. The cryotherapy adhesion device comprises a remote control assembly, a valve assembly, a needle catheter assembly and an gas bottle; the remote control assembly comprises an outer sleeve structure and a remote controller installed on the outer sleeve structure, and the outer sleeve structure is provided with a catheter channel used for being penetrated through by the needle catheter assembly; two ends of the valve assembly are connected with the needle catheter assembly and the gas bottle respectively; the outer sleeve structure can extrudethe needle catheter assembly, and when extruded, the needle catheter assembly can move along with the outer sleeve structure under the action of friction force between an inner wall of the catheter channel and the needle catheter assembly; the remote controller is used for sending a trigger signal to the valve assembly when triggered; and the valve assembly is used for transporting gas in the gasbottle to the needle catheter assembly when receiving the trigger signal, so as to make the needle catheter assembly conduct cryotherapy.

Description

technical field [0001] The invention relates to the field of cryoadhesion medical devices, in particular to a cryoadhesion device. Background technique [0002] Cryoadhesion is commonly used in frozen biopsy, frozen section or foreign body removal in the natural cavity of the human body. It has the advantages of large sampling volume and strong adhesion. Transcavity cryoadhesion has been developed relatively maturely, common techniques such as carbon dioxide throttling cryoadhesion. [0003] In the existing related technology, the equipment for cryoadhesion all adopts flexible cryoprobe, main engine, foot switch and gas cylinder. It is delivered to the host, and then delivered to the inside of the flexible cryoprobe, and finally the needle is cooled and adhered to the tissue. [0004] However, cryoadhesion is generally performed with the assistance of an endoscope (soft type). The doctor holds the endoscope in his left hand and operates the cryoadhesion equipment with his ...
