description The invention provides a surgical stitching instrument driving device. The surgical stitching instrument driving device comprises a ratchet mechanism, a cam mechanism, a transmission gear, a first push rod, a second push rod, a trigger, a shell, a limiting assembly and a spring assembly. The first push rod and the second push rod are controlled at the same time to conduct linear motion, operation is conducted only with one hand, and operation inconvenience caused by double-hand operation is avoided; the first push rod and the second push rod are driven through a ratchet wheel-cam mechanism, the shape of a cam is designed, so that one step in the suture operation is completed every time a trigger is pulled, the whole suture operation can be completed only by pulling the trigger, and operation is convenient; the first cam and the second cam are fixed to the two end faces of the output gear, and the size of the device is reduced. 本发明提供一种手术缝合器驱动装置，包括：棘轮机构、凸轮机构、传动齿轮、第一推杆、第二推杆、扳机、壳体、限位组件和弹簧组件。本发明同时控制第一推杆和第二推杆进行直线运动
