Abstract

The invention belongs to the field of medical devices, and discloses a slide fastener biological absorbable support and a preparing method thereof. The slide fastener biological absorbable support comprises a mesh-shaped structure body, an outer support, an upper side slide fastener, a lower side slide fastener, a support fastener and an inner support. The inner support is of a sheet-shaped structure. The mesh-shaped structure body is embedded in the inner support. The mesh-shaped structure body is formed by mixing squares and triangles. The upper side and the lower side of the mesh-shaped structure body are each of a square structure, and the middle of the mesh-shaped structure body is of a triangle structure. The upper side slide fastener and the lower side slide fastener are embedded inthe two sides of the inner support and are protruding slide fasteners. The outer support is connected with the inner support, and the support fastener is arranged on the surface. The support fasteneris a protruding fastener and has the length of 0.6-1 mm, the inner support and the outer support are made of a new polymer generated by copolymerizing and mixing high-molecular polymers (polylactic acid, polycaprolactone and the like) and different polymers and have quite high biocompatibility, and the support is conveyed to a lesion position through a conveying device.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a sliding buckle bioabsorbable bracket and a preparation method thereof. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Stents are usually implanted in stenotic areas such as trachea, ducts, and blood vessels, which can effectively maintain the patency of the official lumen. Traditional stents can be divided into self-expandable stents and balloon-expandable stents. The former is mainly a high-intensity compound containing memory alloy, which is pre-placed between catheters and maintained by its own expansion mechanism after being introduced into the lesion. The smoothness of the official cavity; the latter itself has no self-expanding characteristics. It is preset on the balloon and reaches the lesion according to the guidance of the guide. The expansion of the balloon produces plasticity, ...
