Embodiment Construction

[0023] The present invention will be further described in conjunction with accompanying drawing and embodiment now.

[0024] Such as figure 1 , figure 2 As shown, a novel anatomical lung volume reduction elastic stent includes a stent body 1 , a spherical structure 2 , a U-shaped loop 3 , and a development mark 4 . Wherein, the spherical structure 2 is fixed on both ends of the bracket body; the U-shaped loop is located at one end of the bracket body; and the developing mark is fixed on the bracket body and the U-shaped loop.

[0025] The bracket body 1 is made of nickel-titanium alloy through heat setting treatment, and is in a straight line state at room temperature. In actual clinical practice, after the stent is implanted in the body, the nickel-titanium shape memory alloy returns to the state of the distal U-shaped structure at a body temperature of 37 degrees Celsius. Thereby, the diseased alveolar tissue is compressed, and the effect of lung volume reduction is achi...

Abstract

The invention relates to the technical field of medical appliances, discloses a device for implementing lung volume reduction surgery, and particularly discloses an anatomical lung volume reduction elastic bracket, which can be implanted into a human lung. The anatomical lung volume reduction elastic bracket can be implanted into the tail end of the lung bronchus of a patient in a minimally invasive manner in order to eliminate the influence of tissues with severe emphysema lesion on lung function and achieve the effect of treating chronic diffuse emphysema. The anatomical lung volume reduction elastic bracket comprises a bracket body and spherical structures which are fixed to the two ends of the bracket respectively. The bracket is at a linear state at the normal temperature, and is in a U-shaped state after being released in vivo.

Description

technical field [0001] The invention relates to the technical field of medical devices, and is a device for performing lung volume reduction surgery, specifically an anatomical lung volume reduction elastic bracket that can be implanted into human lungs. The bracket is suitable for patients with emphysema , Emphysema volume reduction therapy can be implemented under bronchoscopy. Background technique [0002] Obstructive pulmonary diseases, such as emphysema, have a high incidence worldwide, and are characterized by high mortality and high disability rates. At present, internal medicine is mostly used to treat severe emphysema, such as bronchiectasis drugs Symptoms can be relieved, and oxygen inhalation and ventilator-assisted treatment can prolong the patient's life, but these methods are very limited in improving the patient's symptoms and prolonging the survival rate. Over the years, people have been looking for new ways to treat chronic diffuse emphysema. In recent year...
