AI Technical Summary
Existing vascular occlusion devices cannot adjust the occlusion position after the anchor is released, which can easily lead to occlusion failure due to misjudgment, especially in areas of tortuous or narrow blood vessels.
A retractable and adjustable vascular occlusion device was designed, comprising an occlusion unit, a delivery unit, an operating handle, and an adjustment unit. The tilt angle of the anchor piece within the blood vessel is adjusted by pulling the sutures in the adjustment unit. Combined with a dual feedback mechanism of an indicator axis and a return vessel, the accurate positioning of the anchor piece is ensured.
It effectively solves the problem of anchor plate getting stuck in complex anatomical structures, reduces the misjudgment rate, improves the occlusion success rate and device stability, and adapts to the adjustment needs of complex vascular structures.
