AI Technical Summary
Technical Problem
The 360-degree rotation of the suture needle in existing laparoscopic suture devices can easily get stuck in human tissue, causing the suture needle to become stuck and unable to move or to cause abnormal damage to the tissue.
Method used
The design employs a curved needle module, with the curved needle using continuous reciprocating motion. Combined with the suture guide and suture guide reciprocating release mechanism, this ensures that the curved needle moves in an orderly manner during suturing, preventing it from getting stuck in human tissue.
Benefits of technology
This allows for smoother suturing of curved needles in human tissues, avoiding jamming, reducing tissue damage, and improving suturing efficiency and quality.

Abstract
本发明提供了一种适用于腹腔镜往复缝合器的曲针模块，包括曲针安装块，曲针安装块设置有曲针槽，曲针槽内活动设置有曲针，曲针的形状与曲针槽一致，曲针安装块的第一端设置有第一开口和第二开口，第一开口位于曲针槽的前端，第二开口设置有线导头和线导头往复脱离机构，线导头与曲针的穿刺尖端相对应，线导头与缝合线连接，线导头往复脱离机构用于对线导头进行限制或释放。本发明中曲针采用了连续往复的运动方式，相比于曲针360度周回旋转的运动，在穿刺人体组织时会更加顺畅，更好地避免曲针在缝合过程中卡住人体组织等现象，导致曲针卡死无法运动，或对人体组织造成非正常的破坏。
