Abstract: A stapler handle system and a stapler. A drive motor configured to have a specified safe torque range is used to drive a clamping assembly (4) and a firing assembly (3). When the drive motor drives the clamping assembly (4) to move toward the distal end to perform clamping, if the rotation of the drive motor begins to exceed the specified safe torque range, the motor automatically stops operating, such that the clamping assembly (4) stops moving; it is then determined whether a firing recognition component is within a firing recognition area (14); by determining whether firing distance requirements are satisfied, it may be determined whether firing is complete. Thus, during the process of pressing tissue together, the stapler handle system and the stapler can simultaneously control the force used to press tissue together as well as the clamping distance. This avoids problems such as tissue damage and poor stapling effectiveness caused by uneven end effector (2) pressing force.
