Abstract:
Robotic systems and methods for controlling a tool to remove material from a workpiece. Workpieces such as bones are often non-homogenous and have varying density distributions throughout their volumes. In some embodiments, the systems and methods control the feed rate of the tool, the tool path of the tool, and the rotational speed of the tool based on the density distribution in order to provide a desired outcome for a surgical procedure.
Abstract:
A sterile barrier assembly, mounting system, and method for kinematicaliy coupling first and second surgical components together through the sterile barrier assembly so that positioning is repeatable and deterministic.
Abstract:
A tool for use with a surgical robotic manipulator that comprises an energy applicator including a shaft extending along an axis between a proximal end and a distal end. The shaft has an axial-force receiving surface. A tool assembly comprises a support structure to support the energy applicator, an axial connector assembly arranged to engage and releasably lock the energy applicator to the support structure in a locked state, a drive system coupled to the support structure to rotatably drive the shaft of the energy applicator about the axis, a collet assembly cooperating with the axial connector assembly and configured to apply a force to the axial-force receiving surface of the energy applicator in the locked state, and a reference surface. The force includes an axial component directing the energy applicator proximally into continuous contact with the reference surface in the locked state.
Abstract:
A waste collection unit is provided that comprises a vacuum pump and smoke evacuation system including a blower and blower motor. The vacuum pump, the blower, and the blower motor, create noise. This noise is attenuated in first and second sound attenuating enclosures for the vacuum pump and the blower and blower motor. A cleaning system is also provided with rotating liquid delivery devices. An actuator is operatively coupled to the liquid delivery devices to rotate the liquid delivery devices.
Abstract:
An isolated force/torque sensor assembly (10, 110, 210) for a force controlled robot (12) includes an end effector (22, 122, 222) for operatively attaching to an arm (14) of the force controlled robot (12), the end effector (22, 122, 222) having a gripping portion (36, 136, 236) adapted to be gripped by a hand of a user, and a force/torque sensor (42, 142, 242) adapted to be disposed between the gripping portion (36, 136, 236) and the arm (14) of the robot (12), the force/torque sensor (42, 142, 242) having a high force end effector interface (44, 144, 244) adapted to be attached to the arm (14) of the robot (12), a low force end effector interface (48, 148, 248) operatively attached to the gripping portion (36, 136, 236), and a transducer (45, 145, 245) disposed between the high force end effector interface (44, 144, 244) and the low force end effector interface (48, 148, 248) for reacting to loads applied to the low force end effector interface (48, 148, 248) for user controlled positioning of a surgical tool and for generating corresponding output signals, and wherein the transducer (45, 145, 245) is bypassed for high loads.
Abstract:
A camera and drape assembly for use with tracking elements of a surgical system includes a camera unit and a drape covering the camera unit. The camera unit includes a casing presenting a face for facing the tracking elements. Optical sensors are supported by the casing and are exposed through the casing for detecting the tracking elements. The drape covers the camera unit such that light signals from the tracking elements can be received by the optical sensors.
Abstract:
A cleaning module for cleaning bone stock used in surgical procedures. The cleaning module includes a shell. The shell defines a void space to receive the bone stock. A cutter is located within the void space. A shaving tube is coaxially disposed about the cutter to move at different speeds and/or directions relative to the cutter. When actuated, the cutter rotates to clean the bone stock by cutting soft tissue from the bone stock. A tumble plate reorients the bone stock, while an arm moves across the tumble plate from a disengaged position to an engaged position to press the bone stock into the cutter through a window in the shaving tube. A drive assembly actuates the cutter, shaving tube, arm and tumble plate.
Abstract:
A fluid delivery system is provided for delivering fluid to a patient. The system comprises a reservoir for storing the fluid to be delivered to the patient and a fluid discharge device operatively coupled to the reservoir for delivering the fluid from the reservoir to the patient. A controller is configured to operate the fluid discharge device. An input device is in electronic communication with the controller and configured for setting at least one operating parameter of the system. The controller operates the fluid discharge device based on the at least one operating parameter and locks the system after the at least one operating parameter is set such that the at least one operating parameter is unable to be modified. A display is in electronic communication with the controller to at least periodically display a code for resetting the at least one operating parameter. The code is altered at least once during use. The controller is further configured to unlock the system upon receiving the code thereby allowing a user to reset the at least one operating parameter.
Abstract:
A robotic cutting system including a robotic manipulator and a cutting tool coupled to the robotic manipulator. The cutting tool comprises a saw blade. A controller is also coupled to the robotic manipulator. The controller is configured to control operation of the robotic manipulator, the cutting tool, and/or another cutting tool, to cut the bone in an initial stage of cutting until a notch is created in the bone at a predetermined depth. A final stage of cutting is then completed by cutting along the cutting plane.
Abstract:
Tracking devices for use in a navigation system and methods of manufacturing the same. The tracking device comprises a tracking head and a plurality of emitters supported by the tracking head to emit light. A plurality of dome-shaped lenses having arcuate inner and outer surfaces define an outer wall of uniform thickness disposed over the emitters so that light is emitted through the outer wall in a manner that minimizes light refraction.
