A vascular suture mechanism.It includes the anterior sheath.Backend sheathThe bending part and the operation part are assembled.Through the limiting position of convex block and arc guide angle, the baffle can not rotate too much.Therefore, each pin can be accurately connected with each tenon；Also,The first and second apertures run through the back sheath and form a track to guide the movement of each needle and avoid the bending of each needle.The plastic ring design can increase the friction of movement.Press the button better；A plurality of magnets can help to better control the effect of puncture stroke；Wrap the knot around the bend.It can solve the problem of knotting outside the suture.Further shorten the operation time.一種血管縫合機構，係包括前端鞘、後端鞘、彎折部及操作部所組設而成，透過凸塊與圓弧導角之限位能使擋片不會旋轉過頭，因此各針能準確地與各卡榫接合；再者，第一孔徑及第二孔徑貫通後端鞘並形成軌道能導引各針移動的軌跡及避免各針彎折；塑膠環設計能增加移動的摩擦力，並使按鈕按壓時更好按；複數磁鐵能助於更好控制穿刺行程之效果；將結纏繞於彎管上，能解決縫線體外打結的問題，進一步縮短手術進行時間。
