Abstract

The invention relates to a narrow cryotherapy system. The narrow cryotherapy system is characterized in that an air outlet of an air source is connected with an air inlet pipeline of a pressure control valve; an air outlet of the pressure control valve is connected with an air inlet pipeline of the low-temperature pipeline and an air inlet pipeline of the normal-temperature pipeline, an air outlet of the low-temperature pipeline is connected with a first air inlet pipeline of the handle, and an air outlet of the normal-temperature pipeline is connected with a first air inlet pipeline of the handle; an air port of the handle is connected with an air port pipeline of the air pump; a first air outlet of the handle is connected with an air inlet pipeline of the equipment air return pipeline valve body; the second air outlet of the handle is in pipeline connection with the air inlet of the catheter; according to the narrow cryotherapy system, the expanded lumen can be torn and cracked, rapid shaping and expansion can be achieved, cryoablation can be conducted at the same time, the expansion effect can be kept to the maximum extent, meanwhile, inflammation exudation and granulation tissue hyperplasia can be inhibited, mucosa thickening and lumen restenosis can be reduced, and therefore the purpose of treating narrow through replacement is achieved.

Description

technical field [0001] The invention relates to the technical field of cryoablation, in particular to a stricture cryotherapy system. Background technique [0002] Central airway stenosis refers to airway stenosis caused by various lesions (benign and malignant) in the trachea, left and right main bronchus, and right middle bronchus, which can lead to different degrees of dyspnea and even death from suffocation in patients clinically. Common causes of central airway stenosis include benign and malignant tumors in the airway, granulomatous lesions, airway stenosis secondary to injury, inflammatory stenosis, congenital causes, and other special causes. Central airway stenosis caused by granulation tissue hyperplasia, scar tissue contracture, long-term airway intubation, tracheostomy, etc. is relatively common. Among them, bronchial tuberculosis is still the primary cause of benign airway stenosis in China. Although there is no statistical survey data on the incidence of benig...
