Abstract
A closure drive mechanism and a surgical stapler are provided, including: a linkage assembly including a first pivot portion and a second pivot portion, where the first pivot portion is configured to be pivotally connected to the instrument body, and the second pivot portion is configured to be located on a proximal side of the first pivot portion; a movable handle including a first mating portion; a closure drive assembly configured to be pivotally connected to the second pivot portion of the linkage assembly. When the linkage assembly is in a first state and the movable handle rotates in a first direction, the first mating portion drives the linkage assembly to enter a second state, the second pivot portion of the linkage assembly moves proximally and drives the closure drive assembly to move proximally, so the stapler is closed.
