AI Technical Summary
In current coronary interventional treatments, the guidewire diameter is small, making it difficult for doctors to operate and prone to tremors. Multiple guidewires are also difficult to manage and temporarily fix. Existing devices cannot achieve multiple guidewire management, which increases the difficulty of operation and the risk of vascular injury.
Design a coronary intervention guidewire-assisted insertion and fixation device, including an adhesive base, a V-shaped groove and a wing-shaped structure, integrating a limiting and storage structure to achieve automatic guidewire alignment, multi-guidewire anti-entanglement and temporary fixation, suitable for various coronary intervention surgeries.
It improves the alignment efficiency of guidewires with balloons/stents, reduces the difficulty of operation, prevents multiple guidewires from becoming entangled, frees up the doctor's hands, and improves surgical efficiency and safety.

4. The coronary intervention guide wire assisted threading and fixation device according to claim 3, characterized in that, The limiting structure is a limiting groove formed on the wing-shaped structure. The groove opening width is greater than the groove bottom width, and the size gradually decreases from the groove opening to the groove bottom.
5. The coronary intervention guide wire assisted threading and fixation device, according to claim 3, wherein, The storage structure is an arc-shaped groove formed on the wing-shaped structure, with the arc-shaped groove opening upwards and its arc-shaped encirclement angle being 260° to 280°.
6. The coronary intervention guide wire assisted threading and fixation device, according to claim 1, wherein, The storage structure is a C-shaped ring fixed to a wing-shaped structure.
7. The coronary intervention guide wire assisted threading and fixation device according to claim 6, characterized in that, The C-shaped buckle contains a magnet for attracting the guide wire.
8. The coronary intervention guide wire assisted threading and fixation device according to claim 1, characterized in that, The adhesive base includes a base body and a medical double-sided adhesive layer disposed on the lower surface of the base body.
9. The coronary intervention guide wire assisted threading and fixation device according to claim 8, characterized in that, The base body, V-shaped groove, and wing-shaped structure are integrally injection molded from medical polymer materials.
