Abstract

The invention provides a cryo-adhesion device, comprising: a remote control assembly, a valve body assembly, a needle catheter assembly and a gas cylinder; the remote control assembly includes an outer casing structure and a remote control mounted on the outer casing structure, and the outer casing structure is provided with a The two ends of the valve body assembly are respectively connected to the needle catheter assembly and the gas cylinder; the outer sleeve structure can squeeze the needle catheter assembly, and keeps the When squeezed, the needle catheter assembly can move together with the outer casing structure under the action of the friction force between the inner wall of the catheter channel and the needle catheter assembly; the remote control is used to send the valve body assembly to the valve body assembly when triggered Sending a trigger signal; the valve body assembly is used for delivering the gas of the gas cylinder to the needle catheter assembly when receiving the trigger signal, so that the needle catheter assembly can perform freezing.

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 ...
