Description

Novel bronchus fistula plugging support

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a novel bronchus fistula plugging bracket.

Background

Bronchopleural fistulae refer to the interconnection traffic of the pleural cavity and bronchi. It is a common complication after thoracic surgery with a broncho-pleural fistula incidence of 1.5% to 28% after pneumonectomy, with a incidence of 4.5% to 20% after total pneumonectomy. Bronchopleural fistulas often incorporate a abscess, and the course of the disease persists, one of the main causes of mortality following pneumonectomy. Bronchi-pleural fistulae also sometimes occur for benign lesions such as tuberculosis, bronchiectasis, chronic obstructive pulmonary disease, and the like. At present, there is no effective method for treating bronchopleural fistula and chronic refractory empyema clinically, and the empyema is more common in the field of general chest surgery. The treatment difficulty is high, the cure rate is low, the treatment period is long, the physical and psychological pain of the patient is caused, and the treatment cost is high.

The aperture of the orifice of some existing bronchus fistula plugging brackets is larger, and when the bronchus fistula plugging brackets are placed and fixed, the risk that other devices fall into the trachea from the orifice of the bronchus fistula plugging brackets is easily caused.

Disclosure of Invention

The utility model aims to at least solve one of the technical problems in the prior art, and provides a novel bronchus fistula plugging bracket which can be used for fixing the position of a cylindrical bracket by using a silicone bracket, ensuring the firmness of the cylindrical bracket, is convenient to install at the position, can avoid the risk that other devices fall into a trachea through a cylindrical metal grid through a grid funnel, has a simple structure, is convenient to place, has little pain for a patient, and can effectively relieve stenosis or plug a fistula, thereby improving ventilation of the patient.

The utility model also provides a novel bronchus fistula plugging support, which comprises a silicone support and a cylindrical support, wherein the cylindrical support consists of a first sealing ring, a second sealing ring, a metal grid and a grid funnel, the metal grid is cylindrical, two ends of the metal grid are respectively connected with the first sealing ring and the second sealing ring, and the grid funnel is arranged in the right end of the metal grid. The silicone stent can be used for fixing the position of the cylindrical stent, and meanwhile, the silicone stent has the advantages of simple structure, convenient placement and less pain for patients, and can effectively relieve stenosis or block the fistula, thereby improving ventilation of the patients.

According to the novel bronchus fistula plugging bracket, the cylindrical bracket is arranged in the silicone bracket and is sealed and fixed through the first sealing ring and the second sealing ring. The cylindrical metal mesh can be conveniently mounted on the silicone support.

According to the novel bronchus fistula plugging bracket, the grid funnel is formed by inwards folding the right end of the metal grid, and the grid funnel and the cylindrical metal grid are integrally formed.

According to the novel bronchus fistula plugging bracket, the first sealing ring and the second sealing ring are both in a circular shape, so that the novel bronchus fistula plugging bracket is convenient to install at two ends of a metal grid.

According to the novel bronchostomy occlusion stent, the silicone stent is cylindrical in shape. The cylinder support is conveniently installed in the silicone support.

Additional aspects and advantages of the utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model.
