Improved end effector for wound closure device

A suture device with a composite end effector. The composite end effector includes a suture with an unmodified fixation element at a distal end and an overlying attachment piece disposed over the proximal end of the unmodified fixation element. The resulting composite end effector has improved strength and avoids the need for affixation methods such as welding or chemical affixation. 种具有复合端部执行器的缝合线装置，所述复合端部执行器包括缝合线，所述缝合线在远侧端部具有未修改的固定元件和设置在所述未修改的固定元件的所述近侧端部上的叠置附接件。所述所得的复合端部执行器具有改善的强度并且避免了对诸如焊接或化学附接等附接方法的需要。
