3D print tracheal stent

Abstract

The invention discloses a 3D print tracheal stent. The tracheal stent comprises an inner stent and an outer stent, wherein the inner stent and the outer stent are each arranged as ring-shaped stent, and the outer diameter of the outer stent is larger than that of the inner stent, while the thickness of the inner stent is larger than that of the outer stent, and the space between the inner stent and the outer stent is connected through uniformly distributed support rods; the center of the inner stent is arranged as a central trachea. By the 3D print tracheal stent, the central tracheal stents are arranged as two layers, the central trachea is arranged in the center hole inside the inner stent; the inner and outer support structures can be arranged in several ways: spiral shape, dot-like distribution, linear or circular structure, the external supports of different structures can be adapted to different medical symptoms, and the solid support degrees of these structures are all very strong, and the stent has the characteristics of being small in stress area, significant in reducing the degree of stimulation of the trachea, and easy to use.

Description

technical field [0001] The invention relates to the field of medical facilities, in particular to a 3D printed tracheal stent. Background technique [0002] In the existing medical field, 3D printing technology has been used in many aspects to better help solve patients' problems. For example, in orthopedics, it is convenient to print the bone outline through a scanning device, and in dentistry, it can print out the whole interior of the tooth cavity. , to understand the patient's problems more intuitively; in the medical field, bronchomalacia is a disease caused by the deterioration of muscle elasticity and softening of the bronchi. This disease seriously affects people's breathing, which can lead to intermittent asphyxia and difficulty breathing For severe diseases such as pulmonary infection, most of the existing medical technologies use a tracheal stent to be placed into the respiratory tract to support the trachea in the respiratory tract to achieve the purpose of allow...

[0002] In the existing medical field, 3D printing technology has been used in many aspects to better help solve patients' problems. For example, in orthopedics, it is convenient to print the outline of the bone through a scanning device, and in dentistry, it can print out the entire interior of the tooth cavity. , to understand the patient's problems more intuitively; in the medical field, bronchomalacia is a disease caused by the deterioration of muscle elasticity and softening of the bronchi. For severe diseases such as pulmonary infection, most of the existing medical technologies use a tracheal stent to be placed into the respiratory tract to support the trachea in the respiratory tract to achieve the purpose of allowing the patient to breathe normally; the current tracheal stent has a relatively simple structure, and the breathing There is only one pipeline; and when the support is embedded, the stimulation is relatively large, and if the stimulation is reduced, the fixed support force will be smaller, causing the bracket to slip
