Abstract: A force transmission mechanism for a teleoperated surgical instrument may include a gear, a push/pull drive element, and a connection element. The push/pull drive element may be configured to transmit force to actuate an end effector of the surgical instrument and to rotate with a shaft of the surgical instrument when the shaft is rotated by the force transmission mechanism. The connection element may operatively couple the gear and the push/pull drive element. The connection element may be configured to convert rotational movement of the gear to a substantially linear movement of the push/pull drive element. The connection element may be configured to rotate with the push/pull drive element and relative to the gear.
