Номер: US20200345372A1

A handle assembly and a stapler including the same are provided. The handle assembly includes a first handle, a second handle, a slot provided in the second handle and a slider slidably located in the slot. When the slider is in the first section of the slot, the first handle and the second handle are not linked; when the slider is in the second section of the slot, the first handle is linked to the second handle and actuates the second handle to move from an insurance position to a firing position. Therefore, only the movement of the second handle can fire the stapler. No matter whether the stapler is ready to be fired or not, the first handle can be pressed by the doctor, while the stapler cannot be fired when the stapler is not ready to be fired.
