Window hole type valve and bracket for reducing lung volume

Abstract

A window opening type valve lung capacity-reducing support is characterized in that: the support mainly comprises a netlike framework (1) and a one-way valve (3); the cylindrical part of the one-way valve (3) is connected with the netlike framework (1); the joint of the netlike framework (1) and the one-way valve (3) is connected with more than two surface support wires (2) which support the one-way valve (3); the far ends of the surface support wires (2) are furled on one end of the one-way valve (3) not connected with the netlike framework (1); the one-way valve (3) is of a double-layer structure and consists of an inner layer valve (4) and an outer layer window opening type petal (6); the inner layer valve (4) is provided with two to four valves (5), while the outer petal (6) is provided with two to four window openings (7); moreover, each window opening (7) is arranged at a central position corresponding to the valves (5). The window opening type valve lung capacity-reducing support has the characteristics of simple structure, convenient posting, less pain in a patient, less complicating disease and wide application range, etc.; moreover, the support not only can reach the effect of thoracotomy lung capacity-reducing surgery, but also can avoid the disadvantages of a thoracotomy including heavy trauma, difficult positioning, high requirement on lung function, more postsurgical complicating disease and high death rate.

Description

Technical field [0001] The invention relates to a medical instrument, in particular to a stent for minimally invasive lung surgery, in particular to a window hole type valve lung volume reduction stent. Background technique [0002] At present, chronic obstructive pulmonary disease such as emphysema is a common disease, especially in the elderly. Traditionally, the treatment of emphysema is mainly based on internal medicine, including oxygen inhalation, prevention of lung infections, bronchospasm, etc., but the curative effect is extremely limited. Surgery is mostly based on lung volume reduction surgery, when the patient’s own lung function is relatively high. Poor often cannot tolerate surgery, so the mortality rate is high, which limits the application of surgery. According to statistics, the 5-year survival rate of patients with end-stage emphysema is less than 50%. [0003] In recent years, some scholars have proposed the use of bronchoscopy for lung volume reduction. This m...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems of conventional treatment of chronic obstructive pulmonary disease such as emphysema with low curative effect, large trauma, high requirements on lung function, many complications, high mortality rate and high cost, and design a minimally invasive , simple operation, low risk, less pain for patients, good curative effect, less complications, and a wide range of applications can achieve the same curative effect as surgical lung volume reduction fenestration valve lung volume reduction stent
