Silicone stent, implanting system and manufacturing method

Abstract

Embodiments of the invention provide a silicone stent, an implanting system and a manufacturing method, and relates to the technical field of medical apparatus and instruments. The silicone stent includes a mesh frame and a silicone body formed on the mesh frame. As the stent body of the silicone stent is jointly formed by the mesh frame and the silicone body and the mesh frame circumferentially covers the silicone body, the mesh frame on an axial direction can extend to the far end of the silicone body from the near end of the silicone body, so that the supporting force of the stent body canbe effectively enhanced through the mesh frame; compared with the supporting force, which is provided by silicone bodies, of the stent bodies of existing silicone stents, the provided silicone stent can greatly decreased the wall thickness of the stent body, so that the silicone stent can be placed in an implanting device during implantation; and as the silicone stent can be implanted under the side view of a soft bronchoscope by adopting a traditional OTW manner through the implanting device, implanting difficulty and operation difficulty can be reduced, so that the learning curves of implanting operation can be effectively shortened.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a silicone stent, an implantation system and a manufacturing method. Background technique [0002] An endotracheal stent is a support that is inserted into the trachea and has certain tension and elasticity. The endotracheal stent is inserted into the trachea to stretch the trachea to ensure the smooth flow of the trachea. Existing endotracheal stents are divided into metal stents and non-metallic stents. Non-metallic stents are further divided into silicone stents and plastic stents. After long-term clinical research, it is found that the long-term complications of silicone stents such as granulation hyperplasia and scar stenosis are significantly less than those of metal stents, and they are easy to remove after long-term placement. Therefore, silicone stents are recommended for benign trachea that require stent treatment. Stenosis patients. [0003] However, when th...
