Human body cavity plugging device

Abstract

The invention provides a human body cavity plugging device which comprises a clamping rod, a support arranged on the outer side of the clamping rod in a sleeving mode, an inner threaded pipe connected to the lower end of the support in an abutting mode and used for fixing the clamping rod, and an anchor-shaped support fixed to the bottom of the inner threaded pipe. The stent comprises a stent connecting ring fixed to the upper end of the inner threaded pipe and stent rods evenly fixed to the circumference of the stent connecting ring and used for supporting the inner wall of a human body cavity, and an elastic stent film covering layer is pasted to the outer surface of the stent. The clamping rod penetrates through the support and is in threaded connection with the inner threaded pipe. Through cooperative arrangement of the clamping rod and the inner threaded pipe, the unfolding size of the support is adjustable, so that the position of the plugging device can be conveniently corrected after the plugging device is released, and the plugging device can be applied to cavities of different sizes and shapes; the blind hole used for loading the medicine for preventing endothelialization is formed, so that endothelialization between the plugging device and the inner wall of the cavity is prevented; the anti-inflammatory reaction drug coating is coated on the outer surface, so that inflammatory reaction between the plugging device and the inner wall of the cavity is prevented.

Description

technical field [0001] The invention relates to the technical field of interventional therapy, in particular to a human body cavity blocking device. Background technique [0002] Chronic obstructive pulmonary disease, such as emphysema, is a common lung disease. Traditionally, medical treatment of emphysema includes oxygen inhalation, prevention of pulmonary infection, bronchial spasmolysis, etc., but the efficacy is extremely limited; surgical treatment is mostly based on lung volume reduction surgery, but there are also many limitations, such as Strict surgical indications, there are many complications, anesthesia and complications related to anesthesia, the preoperative efficacy is difficult to predict, and the postoperative results cannot be compensated for the unsatisfactory results caused by too much or too little resection, and high surgical costs In addition, some patients often cannot tolerate surgery due to their poor lung function, so the postoperative mortality ...

AI Technical Summary

Problems solved by technology

[0005] However, the above-mentioned prior art still has the following problems in use: once the blocking device is released, it will be stuck on the inner wall of the human body cavity, resulting in difficulty in position correction; the size of the blocking device is fixed, and cannot be applied to human body cavities of different sizes and shapes The skeleton of the occlusion device is easily endothelialized by the inner wall of the human cavity and cannot be removed; the covering of the occlusion device is likely to cause an inflammatory reaction on the inner wall of the human cavity
