Problems solved by technology

However, due to the limitations of traditional technology and economic conditions, manufacturers are still unable to provide personalized implants quickly and at low cost, and the mass production of serialized shaped products still occupies the mainstream position.
However, due to the differences in the human body and the randomness of the shape of the defect site, the stereotyped implants often cannot meet the requirements, and they must adopt personalized treatment methods and tailor-made personalized implants

Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] One aspect of the present invention provides a tracheal stent 1 for tracheal softening in infants. The tracheal stent 1 is in the shape of a cylinder with a notch, the cross section of the cylinder is "C" shaped, and the center of the "C" notch is The angle is 90°. The inner diameter of the tracheal stent 1 is 6.5 mm, the wall thickness is 0.5 mm, and the length is 50 mm. On the inner side of the tracheal stent, a groove 3 with a width of 1 mm and a depth of 0.1 mm is provided every 5 mm in the longitudinal direction of the stent. On the tube wall of the tracheal stent, at least six square holes 2 with a length of 2 mm and a width of 1 mm are evenly distributed laterally between every two grooves. The tracheal stent 1 is obtai...

Abstract

The invention discloses a tracheal stent for an infant. The tracheal stent is in a cylinder with a gap; the cross section of the cylinder is C-shaped; a central angle of the C-shaped gap is 75-115 DEG C; the inner diameter of the tracheal stent is 6-7mm, the wall thickness is 0.4-0.6mm and the length is 20-100mm; grooves which are 1mm in width and 0.1mm in depth are arranged at the inner side of the tracheal stent in the longitudinal direction of the stent at intervals of 5mm; at least four square holes which are 2mm in length and 1mm in width are transversely distributed between every two grooves evenly; and the tracheal stent is obtained through 3D printing of polyacrylate / polymethacrylate photosensitive resin PIC100.

Description

technical field [0001] The invention relates to a 3D printed tracheal support, in particular to a tracheal support for tracheal softening in infants. Background technique [0002] Tracheomalacia (TM) is a disease in which the airway collapses and narrows due to atrophy or reduction of longitudinal elastic fibers or destruction of airway cartilage integrity. It is divided into congenital tracheomalacia and secondary tracheomalacia (external pressure added). Tracheomalacia in children, especially infants (0-1 years old), is still a global medical problem because of its high morbidity and mortality. [0003] At present, there is no unified standard for tracheomalacia treatment, and conventional treatments include continuous positive airway pressure (CPAP), endotracheal stent implantation, and surgical treatment. [0004] Continuous positive pressure ventilation is an effective means of treating moderate to severe tracheomalacia, which maintains airway patency by establishing a...
