Abstract

A handle assembly and a surgical stapler including the handle assembly is provided, wherein the handle assembly includes a first handle and a second handle. A first limit portion and a second limit portion are provided on one end of the first handle and one end of the second handle, respectively. The first limit portion is on a proximal end side of the second limit portion. As the first handle is at its initial position, the first limit portion abuts the second limit portion to prevent the first handle from rotation in a second direction. In an invalid state, the first handle can still be squeezed; meanwhile, the first and the second limit portions limit the initial angular position of the first handle and the initial position of the second handle. When the first handle is not rotated, the second handle cannot be rotated and the stapler cannot be fired.
