A system includes a cutting device, a tracking and navigation system and a cutting system in operable communication with the cutting device and the tracking and navigation system. The cutting device includes a communication system, a cutting element, and a plurality of optical trackers. The tracking and navigation system is configured to detect a location of optical trackers. The control system is configured to cause the tracking and navigation system to detect the location of the cutting device, determine a revised shape for an implant cavity, cause the cutting device to cut the implant cavity to the revised shape, select a shape for a cone to be placed in the revised implant cavity, and machine the cone to the selected shape.

A surgical system and method of operating the same include a manipulator with a base, a robotic arm coupled to the base, and a saw tool coupled to the robotic arm to perform a cut of a bone. A control system is coupled the manipulator and obtains data defining a cutting plane for the bone and a pre-determined depth of the bone to be cut by the saw tool along the cutting plane. The control system associates a virtual planar boundary with the bone along the cutting plane and controls the manipulator to autonomously align the saw tool to the cutting plane. The control system controls the manipulator to activate and autonomously move the saw tool along the cutting plane to perform the cut. Autonomous movement of the saw tool is constrained to remain within the virtual planar boundary and not exceed the pre-determined depth.

The invention relates to a surgical robotic system comprising a robotic arm (1) holding an end-effector (11) and a control unit (13) configured to controllably move the robotic arm and maintain the end-effector (11) in at least one target position relative to a patient, wherein the control unit is configured to: (i) based on a first input continuously applied by a user onto the robotic arm (1), activate a hand guiding mode wherein the robotic arm is freely movable by the user; (ii) based on a second input different from the first input, continuously applied by the user onto the robotic arm (1), activate a computed trajectory mode wherein the robotic arm moves to a target position according to a computed trajectory; (iii) when the computed trajectory is activated, detect that the end-effector (11) meets at least one predetermined safety condition and automatically switch to a servo-controlled mode wherein the robotic arm (1) is automatically movable to maintain the end-effector (11) in the target position relative to a tracker attached to the patient.

Methods of cutting bone using a robotic cutting system are provided. The robotic cutting system includes one or more controllers, a robotic manipulator, and one or more cutting tools, such as those including a bur or a saw blade, that can be coupled to the robotic manipulator. An initial cut, such as a notch, is made into the bone with the bur or the saw blade. This notch is then used to constrain the saw blade for limiting skiving of the saw blade during cutting along a cutting plane.

A surgical robotic arm includes an instrument having a coupler rotatable about a longitudinal axis, the coupler including: a drive screw; a drive nut threadably coupled to the drive screw, the drive nut movable along the longitudinal axis in response to rotation of the drive screw; and a drive member coupled to the drive nut and movable in response to movement of the drive nut. The surgical robotic arm also includes an instrument drive unit having: a motor configured to engage the coupler and rotate about the longitudinal axis to rotate the coupler and the drive screw; one or more sensors configured to measure one or more properties of the motor; and a controller coupled to the sensor(s) and the motor. The controller is configured to control the motor based on the property of the motor.

A packaging technique for applying an insulating pack to the housing of a battery cell. The insulating pack is formed from a self-adhesive cutout of insulating material by folding the cutout onto the sides of the housing that are to be covered. The packaging technique involves a packaging method for automatically applying an insulating pack, a battery cell including an insulating pack, a packaging station for carrying out the method, and a preparation device for preparing one or more cutouts of insulating material.

Robotic system and methods for preparing a bone of a joint to receive an implant. Virtual object(s) are used to define a volume of material to be removed from the bone for receipt of the implant. A robotic manipulator controls a cutting tool based on the virtual object(s) to form a first cavity and a second cavity in the bone. The second cavity is formed beneath the first cavity and is rotated relative to the first cavity to define an undercut in the bone. The first and second cavities receive a body and a locking member of the implant in an unlocked position. The locking member is rotated within the second cavity to a locked position whereby the undercut engages the locking member to limit withdrawal of the implant from the bone.

A computer-assisted surgery system may have a robotic arm including a surgical tool and a processor communicatively connected to the robotic arm. The processor may be configured to receive, from a neural monitor, a signal indicative of a distance between the surgical tool and a portion of a patient's anatomy including nervous tissue. The processor may be further configured to generate a command for altering a degree to which the robotic arm resists movement based on the signal received from the neural monitor; and send the command to the robotic arm.

An intraosseous access system to access a medullary cavity includes a driver including an access assembly, a motor, and an energy source. The intraosseous access system further includes a sensor configured to detect a first input from one of the motor or the energy source. The intraosseous access system further including a processing unit, communicatively coupled with the sensor, configured to receive the first input from the sensor, and determine access to a medullary cavity. The processing unit can then modify operation of one of the motor and the energy source to automatically stop operation of the system and prevent backwalling.
