A surgical robot with a surgical robot arm and a surgical robot arm controller. The surgical robot arm has a set of joints and a joint controller. The joint controller is configured to drive a joint of the set of joints. The surgical robot arm controller has a processor and watchdog circuitry. The processor is configured to send joint driving signals to the joint controller on a communication link. The watchdog circuitry is configured to: receive sequence values from the processor; determine whether each received sequence value matches a next expected value of a predetermined sequence; and if the received sequence value does not match the next expected value of the predetermined sequence, disable the communication link between the processor and the joint controller.

Watchdog circuitry of a surgical robot arm

A surgical robotic arm drape, the drape comprising: a sheet defining a cavity for housing a robotic arm; and a set of guiding elements attached to the sheet configured to retain a supply line threaded there through for use in a surgical procedure.

Supply line for a robotic arm instrument

A locator of a surgical port of a surgical robot system, the surgical robot system comprising an instrument attached to a robot arm, the instrument having an instrument shaft able to pass through the surgical port to a surgical site, the locator comprising: an interface configured to couple to the surgical port; a mechanism configured to permit relative linear and/or rotational motion of the interface and the instrument shaft; and a controller comprising a processor operable to estimate the position of a part of the robot arm, the controller configured to control the mechanism in dependence on the estimated position of the part of the robot arm such that as the robot arm retracts the instrument from the patient, the locator moves the port away from the robot arm and provides a reaction force to keep the port in place.

Port control

A surgical robot comprising a robot arm base connected to a distal robot arm link via a series of intermediate articulated robot arm links. A robot arm interface is attached to the distal robot arm link. The robot arm interface engages an instrument interface of a surgical instrument, and comprises an instrument engagement source and an instrument engagement detector. The instrument engagement detector is configured to only detect the instrument engagement source when the instrument engagement source is coupled to the instrument engagement detector by a coupler.

Surgical instrument engagement detection

A surgical robot arm () comprises a mounting portion (). The mounting portion () comprises a reader () configured for reading location identifiers (). The mounting portion () fits into a socket () comprising a location identifier (). A signal output from the reader () allows determination of the location of the robot arm ().

Robot arm location

A robot arm having a compound joint between a first limb of the arm and a second limb of the arm, the second limb of the arm being distal of the first limb, the arm comprising: a coupler element coupled to the first limb of the arm by a first revolute joint having a first rotation axis and to the second limb of the arm by a second revolute joint having a second rotation axis; first and second rotational position sensors for sensing the configuration of the arm about the first and second joints respectively; first and second torque sensors for sensing the torque applied about the first and second joints respectively; a control unit for controlling the operation of the arm; a first communications unit borne by the arm and located proximally of the coupler and a second communications unit borne by the arm and located distally of the coupler, each communications unit being capable of encoding data received from one or more of the position and/or torque sensors in a first data format into data packets and transmitting those packets to the control unit in accordance with a packet-based data protocol different from the first data format; wherein the first position sensor is connected by a physical data link running within an exterior wall of the first limb to the first communications unit to so as to pass data representing sensed position about the first joint to the first communications unit for encoding and the first torque sensor is connected by a physical data link running within an exterior wall of the second limb to the second communications unit to so as to pass data representing sensed torque about the first joint to the second communications unit for encoding.

Communication paths for robot arms

A labeling device for a syringe that includes a first labeling subsystem adapted to print a first label having machine readable information and a second labeling subsystem adapted to print a second label having human readable information is disclosed. The first labeling subsystem includes a label applicator adapted to automatically apply the first label to a portion of the syringe. The first labeling subsystem includes a syringe clamp assembly that securely holds the syringe while the label applicator automatically applies a first label to the syringe. The second labeling subsystem includes a removal device adapted to automatically remove a backing material from the second label.

Syringe labeling device

A robotic system including: a robot arm; a camera for capturing motion of the robot arm; an input mechanism for detecting user input; a display device; and a controller. The controller can operate in (i) a first mode configured to drive the display device to display a video stream captured by the camera in a first format and to drive the robot arm such that motion by the user in a first direction causes the robot arm to move a reference part in a second direction; and (ii) a second mode configured to drive the display device to display the video stream in a second format reflected with respect to the first format and to drive the robot arm such that motion by the user in the first direction causes the robot arm to move the reference part in a direction opposite to the second direction.
