Abstract

The invention discloses a controllable antibacterial tracheal stent. The stent comprises a tracheal stent base and an antibacterial coating layer covering the surface of the tracheal stent base, and the antibacterial coating layer is prepared from a biocompatible and biodegradable host material with antibacterial ingredients; the antibacterial ingredients are dispersed in the biocompatible and biodegradable host material, and attached to the surface of the tracheal stent through a physical or chemical method; by adjusting the concentration and geometrical parameters of the antibacterial ingredients in the degradable antibacterial layer, controlled release of the antibacterial ingredients is achieved, and the infection problem caused when the tracheal stent is placed into a human body is efficiently and controllably solved.

Description

technical field

[0001] The invention relates to the technical field of manufacture of tracheal stents, in particular to a controllable antibacterial tracheal stent. Background technique

[0002] Tracheal and bronchial stenosis can be caused by a variety of etiologies, including: inflammatory granuloma, trauma, tracheomalacia, tumor, etc. Tracheal stenosis can cause obstructive pneumonia, atelectasis, and dyspnea, and in severe cases, respiratory failure can occur in patients and be life-threatening.

[0003] Tracheal stent implantation is one of the important means for the treatment of tracheal stenosis, which can quickly relieve dyspnea. Improve clinical symptoms. At present, the tracheal stents that are widely used clinically mainly include metal stents and silicone stents. Metal tracheal stents are mostly made of titanium-nickel memory alloy or stainless steel to weave into a meshed circular tube shape, and can be divided into covered stents and bare stents according t...
