3D printing gas tube bracket

Abstract

The invention discloses a 3D printing gas tube bracket which comprises an inner-layer bracket and an outer-layer bracket, wherein both the inner-layer bracket and the outer-layer bracket are circularring shaped brackets; the outer diameter of the outer-layer bracket is greater than that of the inner-layer bracket; the thickness of the inner-layer bracket is greater than that of the outer-layer bracket; the inner-layer bracket and the outer-layer bracket are connected through uniformly distributed support rods; and a central gas tube is arranged at the center of the inner-layer bracket. Two layers of gas tube brackets are arranged in the 3D printing gas tube bracket, and the central gas tube is arranged in the central hole inside the inner-layer bracket; an outer support structure of the 3D printing gas tube bracket can be spiral structures, dotted distribution structures, straight line shaped structures or circular ring shaped structures, outer supports of different structures can beapplicable to different medical diseases, in addition, the structures are all relatively high in solid support degree and have the characteristics of small stress areas, the stimulation degree of a gas tube can be greatly reduced, and the 3D printing gas tube bracket is convenient to use.

Description

technical field [0001] The invention relates to the field of medical facilities, in particular to a 3D printed trachea 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 allowi...

[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
