A kind of sputum plug cleaning device

Abstract

The invention discloses a device for clearing sputum-thrombus formed in the lung of a patient, especially sputum-thrombus formed in the bronchium of a child. The sputum-thrombus clearing device comprises a hollow sheath catheter with certain flexibility and at least one guide wire which is made of a flexible material and arranged in the hollow sheath catheter and can extend out of or retract into the hollow sheath catheter, the diameter of the guide wire is smaller than the inner diameter of the hollow sheath catheter, one end of the guide wire is fixed to an operation handle at one end of the hollow sheath catheter, and the guide wire can be driven to rotate axially by rotating the operation handle and can be driven to extend out of or retract into the hollow sheath catheter relative to the axial direction of the hollow sheath catheter by pulling or pushing the operation handle. The device can reach any lung segment under the guide of a bronchoscope, the sputum-thrombus can be wound on the device under gripping force generated in a relatively large area due to rotation of the guide wire, breaking of the sputum-thrombus is not prone to occur and the whole sputum-thrombus can be pulled out intactly. The intervention device has good economic benefits and social benefits after being applied clinically.

Description

technical field [0001] The invention relates to a tool used under a medical endoscope. Specifically, the invention is a tool used under a bronchoscope to clean up phlegm plugs formed in a patient's lungs, especially in the small bronchi, especially in children's small bronchi. A device that forms a sputum plug. Background technique [0002] Respiratory tract infectious disease is a common and frequent medical disease, and it is more likely to occur in children. According to incomplete statistics, respiratory infectious diseases account for more than 70% of pediatric outpatients. The incidence of pneumonia in children varies from region to region, but it always ranks first in the spectrum of children's diseases and is still one of the important causes of death in children. Therefore, it is of far-reaching significance to improve the diagnosis and treatment of respiratory diseases in children. [0003] With the continuous expansion and deepening of the application of broncho...

AI Technical Summary

Problems solved by technology

The traditional bronchoscopic methods for clearing sputum plug mainly include alveolar lavage, foreign body forceps, and even biopsy forceps. Edema; due to the relative fragility and looseness of the sputum plug, foreign body forceps and biopsy forceps are easy to pinch off

Therefore, traditional methods cannot fundamentally solve the problem of phlegm plug
