An anti-displacement airway stent

Abstract

The invention discloses an anti-displacement airway support, comprising a first port, a support frame and a second port, the horizontal distance between the support frame and the first port and the second port is equal, the support frame A supporting net is fixedly connected between the first port and the second port, the first port and the second port have the same structure and size, and the first port and the second port are compared with The support frame is arranged symmetrically, a support base is arranged in the center of the support frame, a second support rod is fixedly connected between the support base and the inner wall of the support frame, and the support base and the first port A first connecting rod is fixedly connected between them. When the present invention is in use, it can be combined with the device more closely through the expansion of the tumor body, and at the same time, the structural strength of the device can be improved, and it can be properly stretched and stretched according to the expansion and contraction of the trachea, so that it can better match the inner wall of the patient's trachea , to ensure the smooth breathing of the patient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-displacement airway stent. Background technique [0002] Tracheal and bronchial stenosis caused by inflammatory granuloma, scar, tuberculosis, trauma, tracheomalacia, amyloidosis, tumor and other lesions can cause obstructive pneumonia, atelectasis and dyspnea. Patients have dyspnea, stridor, Severe symptoms such as choking and coughing may cause respiratory failure and be life-threatening. Tracheal stent placement is one of the important means to treat airway stenosis, which can quickly relieve dyspnea and improve clinical symptoms. The application of airway stents can be traced back to the 1890s. In the past 20 years, with the continuous development of material science and the popularization of flexible bronchoscope in clinic, airway stent implantation has been widely used in clinical practice, which provides opportunities for further treatment and improves th...

Problems solved by technology

[0003] However, the existing airway stents are not firmly attached to the trachea wall during use, and are prone to movement, which increases the probability of surgical complications. At the same time, the support of the stent is poor, and it is prone to deformation when it is in a squeezed state for a long time. Brackets don't work as well as they should
