Novel clamping filling type double-capsule bronchus stopper

Abstract

The invention discloses a novel clamping filling type double-capsule bronchus stopper which comprises a stopping catheter, a first cuff, a second cuff, a first inflation valve and a second cuff inflation valve. One end of the stopping catheter bends to the other side and divides the stopping catheter into a straight catheter part and a bent catheter part, and the first cuff and the second cuff arerespectively arranged in the bent catheter part of the stopping catheter and are communicated with the first cuff inflation valve and the second cuff inflation valve which arranged on the straight catheter part through the stopping catheter; the first cuff is close to one end of the stopping cuff catheter, and the volume of the second cuff located on the inside of the bend catheter part of the stopping catheter in the inflatable state accounts for three-quarter of the total volume of the second cuff. The novel clamping filling type double-capsule bronchus stopper has the advantages of simplestructure, flexible and convenient use, and can make the right lung collapse completely in the process of opening the right chest, which is of great significance to the field of thoracic surgery and is easy to be popularized.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a novel pressing-filling double-cuff bronchial occluder. Background technique [0002] At present, double-lumen bronchial intubation or bronchial occluder are often used clinically in thoracic surgery to achieve the effect of collapsing the lung tissue on the surgical side. It is often found in clinical work that it is more convenient and effective to use a bronchial occluder than a double-lumen tube for patients with left chest surgery. works well. However, for the operation of opening the right chest, the bronchial occluder seems a little impractical. Existing bronchial occluders often only have a circular cuff. Due to the short right main bronchus, the opening of the bronchus in the upper lobe of the right lung is too close to the main trachea. collapse, which is not conducive to subsequent surgical operations. Therefore, it is necessary to design a new...

However, for right chest surgery, bronchial occluder is not very practical

Existing bronchial occluders often only have a circular cuff. Because the right main bronchus is relatively short, the opening of the bronchus in the upper lobe of the right lung is too close to the main trachea. Collapsing, which is not conducive to subsequent surgical operations
