Trachea and bronchus stent and preparation method thereof

Abstract

The invention discloses a trachea and bronchus stent. The trachea and bronchus stent comprises a tube body and a branch thereof. According to the trachea and bronchus stent, the computed tomography (CT) and three-dimensional reconstruction technology is used for acquiring bronchial tree information, a data processing device is used for restoring and repairing acquired data, software is used for design and modification, a trachea and bronchus stent three-dimensional design drawing suitable for a bronchial tree is obtained, a three-dimensional printing system is applied for printing forming, and the finished product is obtained. Trachea and bronchus stents designed for different individuals and bronchi using the individuals are high in form degree of adaptability, the problems such as displacement, disengagement, air way mucosa bruise and insufficient supporting are avoided, and the treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, and specifically relates to a trachea and bronchial stent and a preparation method thereof. Background technique [0002] The human respiratory system consists of airways and lungs. The respiratory tract in the lower part of the cricoid cartilage is called the trachea and bronchi. The bronchi branch from the hilum into the lungs to form a bronchial tree. The bronchial tree can transport the inhaled air to the alveoli for gas exchange and produce effective breathing. When the trachea or bronchi are damaged by tumors When factors such as tuberculosis and tuberculosis become narrowed or softened, it may hinder gas delivery, resulting in hypoxia and even suffocation of the patient. At this time, it is necessary to use respiratory intervention technology to support the trachea and bronchus to restore the unobstructed airway. The commonly used trachea and bronchus stents generally do not match...
