Embodiment 1

[0028] The structure of embodiment 1 is as figure 1 As shown, the umbrella skirt 3 of the umbrella-shaped self-expanding occluder is attached to the memory alloy wire 1 with a spiral shape. The center of the umbrella skirt 3 is a central shaft 4, and the proximal end of the central shaft 4 has an operating handle 5. It and the central axis 4 are integral structures. The distal end of the central axis 4 is fixedly connected with a set of extendable anchor hooks 2, and there is also a set of extendable anchor hooks 2 at the connection end between the memory alloy wire 1 and the central axis 4, and the extendable anchor hooks 2 are three pieces of memory alloy metal The wire 1 is unfolded in an anchor shape, and each memory alloy metal wire 1 is in a parabolic shape when unfolded. In Embodiment 1, there are two groups of stretchable anchor hooks 2, and the angles between the stretchable anchor hooks 2 in each group are in the same direction. Outward stretching; the parabolas of ...

Abstract

An umbrella-shaped self-expanding plug for treating the diffuse pneumonectasis is composed of 2-10 Ni-Ti marmem wires, an umbrella skirt attached on said marmem wires to become an umbrella shape, and a developable archor hook arranged on the top of umbrella.

Description

Technical field: [0001] The present invention relates to a medical device, in particular to an umbrella-shaped self-expanding occluder, which can implement emphysema lung volume reduction (Lung Volume reduction for physician, LVRP). Background technique: [0002] The curative effect of medical treatment for severe emphysema is not obvious, and it cannot effectively improve the patient's symptoms and prolong the patient's survival. Lung volume reduction surgery, hereinafter referred to as LVRS, developed in the 1990s, is a new method for the treatment of heterogeneous emphysema, and is known as one of the most exciting advances in thoracic surgery. Through a number of clinical studies on the treatment of emphysema with systematic LVRS, it has been proved that it can improve lung function to a certain extent. Improve the working efficiency of respiratory muscles, thereby reducing the symptoms of dyspnea, improving exercise tolerance and quality of life. However, LVRS also ha...
