Connecting assembly for cardiovascular implants

Abstract

The invention relates to the technical field of medical instruments, in particular to a connecting assembly for cardiovascular implants. The connecting assembly is used for connecting the cardiovascular implants and conveying equipment. The connecting assembly for the cardiovascular implants comprises a first connecting component and a second connecting component which are detachably connected, wherein a plurality of mounting grooves are formed in the assembling end surface of the first connecting component and / or the assembling end surface of the second connecting component and are used for placing mounting parts of the cardiovascular implants; and a threaded hole is formed in the second connecting component and used for being in threaded connection with conveying equipment. When the connecting assembly is used for being connected with the conveying equipment and the cardiovascular implants, the number of connecting ends or closing structures is reduced, the risk of generating micro thrombus is effectively reduced, besides, stress on all parts of the implants is more uniform, the structure is simple, welding spots are avoided, in addition, the foreign matter content and the surface area are reduced, and the corrosion risk is reduced.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a connection assembly for cardiovascular implants. Background technique [0002] Such as figure 1 As mentioned above, most of the cardiovascular implants commonly used in the market use metal tubes to be cut by laser, and then heat-treated to shape, or as Figure 2 to Figure 4 As shown, the metal wire is used to weave, and then heat-treated to shape. However, many cardiovascular implants are connected to delivery devices by threads, so tubular cardiovascular implants usually need to be additionally connected with a threaded structure 1 ′ at the connection end 21 ′, while silk braided cardiovascular implants Not only the threaded structure 1' needs to be installed at the connection end 21', but also the braided wire needs to be closed to form a closed-loop structure. At present, it is mainly realized by welding all the braided wires into the tubular structure o...

AI Technical Summary

Problems solved by technology

[0003] First, since the braided cardiovascular implant 3' and the tubular cardiovascular implant 2' need to be connected to the threaded structure 1' at the connection end 21', the height of the raised part is inevitably increased, increasing the risk of microthrombosis

[0004] Second, all the braided wires of the silk braided cardiovascular implant 3' penetrate into the tubular structure, which will cause the braided wires to be partially staggered and stacked, which will lead to uneven stress on each part of the implant, which is extremely difficult during the operation. It is easy to get into the sheath, and when it is released from the sheath, the implant is extremely prone to deviation and twist, which affects the normal release and recovery, and even endangers the life of the patient

[0005] Third, whether it is a silk-braided cardiovascular implant 3' or a tubular cardiovascular implant 2', an additional thread structure is required, especially the silk-braided cardiovascular implant 3' also requires a welded closure structure 31', there are more solder joints, which increases the risk of falling off. In addition, it also increases the foreign matter content in the body and the overall surface area, thereby increasing the risk of corrosion
