微导管及介入系统
By designing a microcatheter system that includes a catheter body, a drive component, a compression component, and an elastic component, the problem of insufficient support force of microcatheters was solved, the ability of guidewires to pass through occluded lesion segments was improved, friction was reduced, and the success rate of surgery was increased.

AI Technical Summary
Existing microcatheters, when used with guidewires, lack sufficient support, making it difficult to pass through occluded lesion segments longer than 20 mm, leading to surgical failure.
Design a microcatheter system comprising a catheter body, a drive component, a compression component, an elastic component, and a first axial limiting component. The drive component drives the compression component to move axially along the catheter body, compressing the elastic component to protrude into the lumen, thereby enhancing the axial support force on the guidewire. After passing through the occluded lesion segment, the fit between the guidewire and the microcatheter is restored.
It improves the guidewire's ability to traverse occluded lesion segments, reduces friction during microcatheter retraction, facilitates the introduction of subsequent treatment devices, and increases the success rate of surgery.
