Knuckle joint assembly for a medical device support system. The knuckle joint assembly includes a cartridge assembly that includes a cartridge housing and a rotary bearing. The cartridge housing includes a bore having a central axis and a bearing mount in the bore. The rotary bearing is press fitted in the bearing mount and configured to receive axially therethrough a spindle to rotatably support the spindle about the central axis. The knuckle joint assembly includes a retaining clip and a retaining pin. The retaining clip is selectively movable to disengage and engage a groove in a spindle to respectively support or release the spindle along a central axis. The retaining pin is movable between a first position to allow movement of the retaining clip between positions but prevent removal of the retaining clip, and a second position to block movement of the retaining clip from the engaged position.

Disclosed is an articulated support arm for an elongated flexible medical instrument, including: a segment rotating about an axis of rotation, a radial brake for preventing rotation of the segment about the axis of rotation, including: a supply of hydraulic fluid, a piston whose stroke along the direction of the axis of rotation, due to the pressure of the hydraulic fluid, prevents rotation of the segment about the axis of rotation, the piston being an annular piston having a hollow center about the axis of rotation, the supply of hydraulic fluid passing through the hollow center.

Implementations relate to a configurable counterbalance mechanism. In some implementations, a counterbalance apparatus includes a spring, a tension element coupled between the spring and a mechanical ground, a base element coupled to a load, and a configurable arm rotatably coupled to the base element. A first pulley and a second pulley are rotatably coupled to the configurable arm, the second pulley orbitable about the first axis, and the tension element is at least partially wrapped around the first pulley and the second pulley. The configurable arm is rotatably configurable at either a first orientation or a second orientation, where the first orientation is associated with a center of gravity of the load located on a first side of the counterbalance apparatus and the second orientation is associated with the center of gravity of the load located on a second side of the counterbalance apparatus opposite to the first side.

A system and method may be used to position or orient a camera within a surgical field. A method may include generating a graphical user interface including a first set of instructions to reposition the camera, and determining whether the camera is within a target volume location. The method may include automatically outputting an indication when the camera is within the target volume location. The method may include outputting a second set of instructions for display on the graphical user interface to align a laser, coupled to or integrated into the camera, to the tracker by changing an angle of the camera
