Abstract: Surgical systems and methods involve a robotic manipulator with a force sensor and a surgical tool that holds a screw. The screw has a known thread geometry. A navigation system tracks a pose of a target anatomy. Controller(s) store the known thread geometry and control the robotic manipulator to maintain the rotational axis on a planned trajectory with respect to the target anatomy based on the tracked pose of the target anatomy. The controller(s) detect, with the force sensor, a force applied by a user. The controller(s) control a rotational rate of the surgical tool to rotate the screw about a rotational axis and an advancement rate of the surgical tool to linearly advance the screw along the planned trajectory. The rotational rate and the advancement rate are based on the force applied by the user and are proportional to the known thread geometry.

Abstract: A conduit for use in association with an air conditioning or refrigeration system. Conduit has first and second conduit portions, and swivel providing fluid communication between first and second conduit portions. Swivel permits rotational movement of the first conduit portion relative to the second conduit portion. Swivel is constrained to prevent linear movement between the first and second portions at the swivel. Conduit also has a fitting for external connection of the conduit to a pressure port of air conditioning or refrigeration system, fitting for fluid communication with the first and second conduit portions. The conduit provides sealed fluid communication from first conduit portion, swivel and second conduit portion to air conditioning or refrigeration system when fitting is connected to air conditioning or refrigeration system. There are also conduit adapters, injection hose assemblies, and charging manifolds with swivels, and methods of utilizing such conduits and swivels.
