The present disclosure relates to an electric surgical stapler, including a handle, the handling having a handle body, a driving motor and a control unit for controlling the driving motor to operate； a working head, including an anvil, a cartridge, a closing mechanism, a firing mechanism, a housing for accommodating the closing mechanism and the firing mechanism, a closing limit switch configured to transmit information of a closing stroke of the closing mechanism to the control unit, and a pressure sensor configured to transmit a pressure value applied to a squeezed tissue during closing to the control unit. The control unit is configured to transmit an instruction of controlling the driving motor to drive movement of the firing mechanism, when the closing limit switch is triggered and the pressure value transmitted by the pressure sensor meets a preset standard. By detecting the closing stroke with the closing limit switch and detecting the pressure with the pressure sensor, there is no excessive squeezing or inadequate squeezing, which ensures that the tissue is squeezed adequately regardless of the thickness, and can ensure stable effect of the staple formation.
