Head position and driver combination instrument

Systems, instruments, and methods for performing a medical procedure. The methods comprise: obtaining a surgical instrument that combines a head positioner and a driver into a single integrated part (the driver being at least partially inserted through an elongate aperture formed in the head positioner so as to extend from a proximal end of the head positioner to a distal end of the head positioner); using an actuable structure of the head positioner to limit an amount that the driver can linearly travel in a first direction within the elongate aperture formed in the head positioner; causing a screw to threadingly engage an object via rotation of the driver in at least a first direction around a central axis of the surgical instrument; and changing an orientation of a receiver via rotation of the head positioner about a portion of the driver.

System and method for breakaway clutching in an articulated arm

A system and method of breakaway clutching in a device includes an arm including a first joint and a control unit coupled to the arm. The control unit includes one or more processors. The control unit switches the first joint from a first state of the first joint to a second state of the first joint in response to an external stimulus applied to the arm exceeding a first threshold, wherein movement of the first joint is more restricted in the first state of the first joint than in the second state of the first joint, switches the first joint from the second state to the first state in response to a speed associated with the first joint falling below a speed threshold, and prevents the switching of the first joint from the first state to the second state when the arm is in a predetermined mode.
