Bracket for lung volume reduction

Abstract

A lung volume reduction stent, belonging to the technical field of medical devices, is characterized in that it is mainly composed of a mesh skeleton (1) and a one-way valve (2), and the one-way valve (2) is a cavity at one end Trumpet-shaped cone or spherical body, the end of the mesh skeleton (1) connected to the one-way valve (2) is also trumpet-shaped, and the horn end of the one-way valve (2) is connected to the mesh skeleton ( The horn ends of 1) are connected, and a support wire (3) is provided on the inner surface of the one-way valve (2), and the support wire (3) is either tightly bonded to the outside of the one-way valve (2), or tightly Bonded on the inner side of the one-way valve (2). The invention has the characteristics of simple structure, convenient insertion, reliable fixation, convenient operation, time saving, less pain for patients, good therapeutic effect, few complications, wide application range and the like. Through minimally invasive technology, it not only achieves the effect of thoracotomy lung volume reduction surgery, but also avoids the disadvantages of thoracotomy surgery such as large trauma, difficult positioning, high requirements on lung function, many postoperative complications, and high mortality. Clinical application prospect and market prospect.

Description

technical field [0001] The invention relates to a medical device, in particular to a support for minimally invasive surgery of the lung, in particular to a lung volume reduction support. Background technique [0002] Pulmonary emphysema refers to a pathological state in which the terminal lung tissue far from the respiratory bronchioles is permanently expanded due to increased residual volume, accompanied by damage to the alveolar septa, resulting in weakened lung tissue elasticity and increased volume. Chronic obstructive pulmonary disease (COPD) is diagnosed when airflow limitation occurs and is not fully reversible. [0003] Emphysema is a common chronic obstructive pulmonary disease. Traditionally, the treatment of emphysema is based on internal medicine, including oxygen inhalation, prevention of lung infection, bronchial spasm, etc., but the curative effect is extremely limited. According to statistics, the 5-year survival rate of patients with end-stage emphysema is...
