Abstract
A closure driving mechanism and a surgical stapler are provided. The closure driving mechanism includes a firing handle, a first slider, a locking member, a closure driver, and an actuating rod. The locking member fits with the first slider when the firing handle is actuated in an initial state and separates from the first slider after the stapler being fired. Therefore, the closure driver is locked by the fit cooperation between the first slider and the locking member after a head assembly is closed, to avoid the pulling sheet from moving distally during a firing process. After the firing process is fired, the locking member no longer locks the closure driver, therefore, the cartridge and the anvil can be opened automatically.
