Embodiment 1

[0043] Refer to attached Figure 1-Figure 4 , Figure 6 , a bronchial occluder system with a foam matrix memory alloy frame structure in this embodiment, including a positioning guide wire 100, an occluder 200, a recovery sheath 300, a push rod 400, a preset recovery line 500 and a catcher 600, The occluder 200 is composed of a foam matrix 210 and a memory alloy frame 220. The catcher 600 is connected to the occluder 200 through a push rod 400. The occluder 200 is provided with a recovery sheath 300, and a preset recovery line is set in the recovery sheath 300. 500, the structure of this design can fit the bronchus to be blocked. This system can implant the occluder 200 in the bronchus to be blocked with the assistance of X-ray, fiberoptic bronchoscope or thoracoscopic. Treats bronchopleural fistula, massive hemoptysis, and lung disorders such as bullae or emphysema.

[0044] The foam matrix 210 of this embodiment is attached to the surface of the memory alloy frame 220, and...

Embodiment 2

[0060] Refer to attached Figure 2-Figure 6 , the basic mechanism of this embodiment is the same as that of Embodiment 1, the difference is that the structure of the occluder of this embodiment is a blood vessel plug-shaped occluder.

Embodiment 3

[0062] Refer to attached Figure 2-Figure 5 , Figure 6 , Figure 7 , the basic mechanism of this embodiment is the same as that of Embodiment 1, the difference is that the structure of the occluder in this embodiment is in the shape of a cylindrical coil.

Abstract

The invention relates to a bronchial occluder system with a foam matrix and memory alloy frame structure,and belongs to the technical field of medical instruments. Thebronchial occluder system with the foam matrix and memory alloy frame structure comprises apositioning guide wire, an occluder, a recovery sheath, a push rod, a preset recovery line and a catcher; the occluder is formed by a foam matrix and a memory alloy frame; the catcher is connected with the occluder through the push rod; the recovery sheath is arranged on the occluder; the preset recovery line is arranged in the recovery sheath; and the designed structure can be attached to the occluded bronchus. According to the system, the occluder can be implanted into the bronchus which needs to be occluded under the assistance of anX-ray, a fiberoptic bronchoscope or a thoracoscope, and is used for treating pulmonary diseases such as bronchus pleural fistula, hemoptysis, pulmonary bulla or emphysema and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to a bronchial occluder system with a foam matrix memory alloy frame structure. Background technique [0002] Clinical indications for bronchial occluder include emphysema, bullae, bronchopleural fistula, intractable massive hemoptysis, and cavitary tuberculosis. However, the bronchial occluders currently used clinically are all congenital atrial defect, ventricular defect, patent ductus arteriosus or patent foramen ovale occluder, because this type of occluder is specially designed for congenital heart disease. The design is not designed according to the shape, structure or function of the bronchial occluder, so it is not easy to completely occlude, fall off or even secondary infection. [0003] Due to air pollution, population aging and other factors, coupled with the increase in the detection rate of small pulmonary nodules, the number of patients with lu...
