A method and device handle having a slide assembly are disclosed for controlling rotational speed of a catheter assembly under various rotational loads. The method includes: driving a catheter assembly at a target rotational speed in a first direction; detecting an actual rotational speed of the catheter assembly in the first direction; comparing the target rotational speed and the actual rotational speed of the catheter assembly in the first direction; and stopping the driving of the catheter assembly in the first direction before a completion of predetermined number of rotations in the first direction when the actual rotational speed decreases a predetermined value over a predetermined time frame.

A method and device handle having a slide assembly are disclosed for controlling rotational speed of a catheter assembly under various rotational loads. The method includes setting a first current limit in a processor, activating the catheter assembly to rotate, calculating a current value in rotational period of a first current limit, updating a second current limit from the first current limit, and wherein the second current limit is lower than the first current limit.

Surgical systems and methods are provided for controlling actuation and movement of various surgical devices.

A robotic surgical instrument for actuating an electromechanical end effector includes a housing, a first input drive, a second input drive, and a shaft assembly. The housing has a proximal end configured to be coupled to an instrument drive unit. The first and second input drives are rotatably disposed within the housing and configured to be drivingly coupled to respective first and second motors of the instrument drive unit. The shaft assembly extends distally from within the housing and includes a shaft and a rod. The shaft has a distal end, and a proximal end operably coupled to the first and second input drives. The rod has a proximal end threadingly coupled to the distal end of the shaft. Rotation of the first and second input drives rotates the shaft to effect axial movement of the rod relative to the shaft.
