Abstract

The invention discloses a vascular stent structure processing device and method, comprising a pretreatment component for feeding and processing the material into a molten state, and the pretreatment component is connected with a first-layer stent body and a second-layer stent body respectively formed The extrusion molding part is connected with a stapling part for fixedly connecting the first layer bracket body and the second layer bracket body; and the second forming pipe, the inner cavity of the first forming pipe and the second forming pipe is suspended with an expansion pipe part with a changeable inner diameter through a bracket, and a driving part for driving the expansion pipe part to expand or contract is installed in the expansion pipe part. The invention mutually blocks the two ruptures, so that the blood vessel stent can resolve the damage to a certain degree by itself.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device and method for processing a vascular stent structure. Background technique [0002] Vascular stents are an important means of treating vascular stenosis and have been widely used in clinical practice. However, most of the current vascular stents have a single-layer mesh structure. After being implanted into the human body, the stents with this structure are easily broken or collapsed by balloon expansion or the impact of blood flow; thus, they lose support before the blood vessel is reshaped. It may even have the risk of causing death, and the safety performance needs to be further improved. [0003] In the prior art, such as a utility model patent with an application number of CN201920174822.X, it mainly solves the above-mentioned problems through a vascular stent with a double-layered tube wall, and the inner and outer layers of the device are difficult to be ...
