AI Technical Summary
Technical Problem
In the existing technology, there is a lack of effective methods to evenly control the suture delivery force during skin suturing, resulting in low suturing efficiency, failure to adequately reduce skin tension, affecting wound healing and increasing scar growth.
Method used
A suture device is used for suture feeding, and barbs are used to absorb the suture. The switching mechanism and trigger are driven by a power source to realize the automatic firing and needle changing of the suture feeding needle, ensuring that the suture is evenly distributed.
Benefits of technology
It improves suturing efficiency, evenly controls the tension of sutures, reduces skin tension, improves wound healing, and reduces scar growth.

Abstract
本发明涉及缝合线输送技术领域。应用倒刺可吸收缝合线皮肤减张缝合的送线方法，采用缝合装置将倒刺可吸收缝合线弹出；缝合装置上设有针仓，针仓内滑动连接有送线针，送线针为中空针体，中空针体内容纳有倒刺可吸收缝合线；缝合装置上设有用于将送线针激发弹出的触发件，触发件将送线针触发击出；缝合装置上设有用于切换触发件正对针仓内的送线针的位置的切换机构；缝合装置包括一动力源，动力源与切换机构联动，动力源还与触发件联动。本专利优化传统手动人工送线进行皮内皮下减张缝合的方式，改良为应用专用缝合装置进行送线。动力源的单次触发，可以实现切换机构与触发件的动作交替进行，进而实现，一次触发，即可实现换针以及送线两项动作。
