AI Technical Summary
Technical Problem
Existing single-helix coils are not effective in vascular embolization and hemostasis, requiring multiple uses and involving complex procedures, which affects embolization efficiency.
Method used
The spring coil with a double helix structure, combined with the guidewire and catheter, achieves efficient embolization and hemostasis through the double helix structure and ciliary design of the silk thread and single-strand spring coil.
Benefits of technology
Reduce the number of devices used, shorten the operation time, achieve stable and controllable vascular embolization and hemostasis, and improve embolization efficiency.

Abstract
本发明公开了一种用于栓塞止血的双螺旋弹簧圈，包括推送导丝、弹簧圈实体及导管；推送导丝的顶部分为两股并均与弹簧圈实体相连接；弹簧圈实体包括单股弹簧圈及丝线，单股弹簧圈有两个且彼此间呈双螺旋结构盘旋延伸，两个单股弹簧圈的下端与推送导丝相连，上端向内弯曲并连接在一起；丝线的两端分别于两个单股弹簧圈相连，丝线有若干个并沿弹簧圈实体的延伸方向间隔排布；导管套接在弹簧圈实体的外侧，当推动推送导丝时，弹簧圈实体可于导管内滑动。本发明通过双螺旋弹簧加丝线的结构形式，能够实现对血管的高效栓塞，相较于传统弹簧圈，减少使用数量，缩短操作时间，栓塞时间更稳定可控，实现有效地、准确地、致密地对血管的栓塞止血。
