DEVICES, SYSTEMS, AND METHODS FOR TORQUE AMPLIFICATION IN MEDICAL SYSTEMS

A medical device may include a main shaft extending from a proximal end to a distal end; an actuator at a proximal portion of the medical device; an end effector positioned at a distal end of the main shaft and comprising a first jaw and a second jaw; a motor; and a torque amplification system. The torque amplification system may include a driveshaft coupled to the motor; a spring coupled to the driveshaft and configured to expand or contract in a proximal or a distal direction relative to the driveshaft; a hammer moveably coupled to the driveshaft; and an anvil coupled to the end effector and abutting the hammer. The anvil may be configured to provide a rotational power output to the end effector to move the first jaw and/or the second jaw.
