摘要：
An endoscopic stitching device includes an actuation shaft, a tool assembly,and adrive assembly. The tool assembly includes a suture needle and a pair of jawstransitionablebetween open and closed positions. Each jaw includes a needle engaging bladeslidablysupported thereon. Each needle engaging blade is transitionable between anextendedposition in which the needle engaging blade engages the suture needle and aretractedposition in which the needle engaging blade is disengaged from the sutureneedle. The driveassembly includes first, second, and third electrical actuators. The firstactuator is operativelycoupled with the actuation shaft to cause axial displacement of the actuationshaft. The axialdisplacement of the actuation shaft causes opening and closing of the pair ofjaws. Thesecond and third actuators are operatively coupled with the needle engagingblades to provideaxial displacement of the needle engaging blades.
