Surgical robotic systems and navigation systems employ a robotic arm including a plurality of links. A link tracker assembly is located on the surface of one or more of the links to enable the link to be tracked by a localizer. The link tracker assemblies can utilize a plurality of tracker elements that can be removably coupled to the link. A photosensor assembly is located on the surface of one or more of the links to receive signals from the localizer for controlling the link tracker assembly. The robotic arm can be coupled to a base and the systems can be used in collaboration with a base tracker that is coupled to the base. The robotic arm can also include a mounting interface for receiving an end effector and the systems can be used in collaboration with an end effector tracker that is coupled to the end effector.

A surgical robot a robotic device and a cart. The cart is coupled to the robotic device and includes a steering assembly. The steering assembly includes wheels and is configured such that the wheels allow the cart to roll in a linear direction when a first mode is selected and the wheels allow the cart to roll in a rotational direction when a second mode is selected.

Steering assembly for surgical robot

A surgical robot includes a robotic arm, a cart supporting the robotic arm and including a steering assembly. The steering assembly comprises wheels and a handle. The handle is moveable to a first position, a second position, and a third position. The steering assembly is configured such that the wheels allow the cart to roll in a longitudinal direction when the handle is in the first position, the wheels allow the cart to be roll a rotational direction when the handle is in the second position, and the wheels allow the cart to roll in a lateral direction when the handle is in the third position.

A portable surgical robot includes a surgical device and a cart. The surgical device is coupled to the cart. The cart includes a chassis, a mount coupled to the chassis, a carriage pivotally coupled to the mount, and a set of wheels. The carriage includes a first bracket positioned at a first lateral end of the carriage and a second bracket positioned at a second lateral end of the carriage. A first wheel of the set of wheels is coupled to the first bracket and a second wheel of the set of wheels is coupled to the second bracket. The carriage is configured to pivot relative to the mount to prevent at least one of (i) rocking of the portable surgical robot, (ii) fluttering of the first wheel, (iii) fluttering of the second wheel, and (iv) tipping of the portable surgical robot.

Carriage for portable surgical robot

A portable surgical robot includes a surgical device and a cart. The surgical device is coupled to the cart. The cart includes a chassis, a frame member, a pair of wheels, and a steering mechanism. The chassis defines a longitudinal axis that extends a length of the cart. The frame member is coupled to the chassis of the cart. The pair of wheels are pivotably coupled to the frame member. The steering mechanism is coupled to the pair of wheels. The steering mechanism is configured to facilitate selectively pivoting the pair of wheels to steer the cart in a plurality of steering modes. The plurality of steering modes include at least one of a fore-and-aft steering mode, a turn-on-axis steering mode, and a lateral steering mode.

Steering mechanism for portable surgical robot

An apparatus and method for non-invasive determination of attributes of human tissue by quantitative infrared spectroscopy. The system includes subsystems optimized to contend with the complexities of the tissue spectrum, high signal-to-noise ratio and photometric accuracy requirements, tissue sampling errors, calibration maintenance problems, and calibration transfer problems. The subsystems include an illumination subsystem, a tissue sampling subsystem, a spectrometer subsystem, a data acquisition subsystem, and a processing subsystem. The invention is applicable, as examples, to determining the concentration or change of concentration of alcohol in human tissue.

Noninvasive determination of alcohol in tissue

A linear positioning apparatus includes an intermediate portion having an axis, and first and second end portions mounted with flexure legs thereto. The flexure legs accommodate motion of the intermediate portion relative to the end portions along the axis, but inhibit motion of the intermediate portion relative to the end portions in directions not parallel to the axis. The apparatus can accommodate forces having off-axis components, and produce motion that comprises substantially no off-axis component. The apparatus is useful in, for example, optical systems where precise linear motion is required.
