The invention relates to a medical system comprising an instrument, a data processing and image generating apparatus and an image display and control unit. Of these, the position acquisition apparatus is embodied to acquire a position and orientation of the instrument in relation to a reference coordinate system. The data processing and image generating apparatus is embodied to generate an image of a body part from currently recorded or stored data representing a body part, which image reproduces a view of the body part together with a representation of the position, and preferably also the orientation, of the instrument in such a way that an observer can gather the position and orientation of the instrument in the body part from the image of the body part. Here, according to the invention, the image display and control unit is wirelessly connected to the data processing and image generating apparatus, and comprises a display and input unit with a closed surface. On the closed surface of the display and input unit, control elements and a respective view of the body part are displayed during operation of the image display and control unit, together with a representation of the position, and preferably also the orientation, of the instrument. The image display and control unit is embodied to accept user inputs via displayed control elements and to transmit control signals to the data processing and image generating apparatus as a function of the respectively accepted user inputs.

Techniques for robotically guiding a cup-shaped implant or instrument are provided. In an example, the technique can include a combination of the following operations. Acquiring a calibration image including a cup-shaped element in a first orientation. Identifying a first elliptical outline of the cup-shaped element. Acquiring a navigation image including the cup-shaped element in a second orientation. Identifying a second elliptical outline of the cup-shaped element. Aligning a coordinate system of a robotic system to a patient, and positioning an implant or instrument based on a pre-operative plan within the coordinate system.

Devices, systems, and methods for a robot-assisted surgery. Navigable instrumentation, which are capable of being navigated by a surgeon using the surgical robot system, and navigation software allow for the navigated placement of interbody fusion devices or other surgical devices. The interbody implant navigation may involve navigation of access instruments (e.g., dilators, retractors, ports), disc preparation instruments, trials, and inserters.

Embodiments of the present disclosure provide a surgical robot system may include an end-effector element configured for controlled movement and positioning and tracking of surgical instruments and objects relative to an image of a patient's anatomical structure. In some embodiments the end-effector and instruments may be tracked by surgical robot system and displayed to a user. In some embodiments, tracking of a target anatomical structure and objects, both in a navigation space and an image space, may be provided by a dynamic reference base located at a position away from the target anatomical structure.

Surgical systems and methods for tracking physical objects near a target site during a surgical procedure are provided, the surgical system employs a navigation system and a surgical instrument; an instrument tracker is provided on the surgical instrument and a patient tracker is provided on the patient's target tissue; the system and method is configured to detect an error condition compromising accuracy of the navigation guidance and to track and monitor a tool-to-bone offset.

A surgical robotic system includes: a surgical table; a plurality of movable carts being oriented toward the surgical table, each of which includes a robotic arm, and an alignment unit configured to determine an orientation of the movable cart and the robotic arm relative to the surgical table; and a computer coupled to each of the plurality of movable carts and configured to calculate a yaw angle for each of the plurality of movable carts.

Disclosed are actuators and power-train sub-systems of Autonomous Motion Systems (AMS), having a Double Dynamic Model (DDM) with combined functionality of control (including continuous controllability), operation (e.g., automated/robotic/autonomous operation in normal mode or safety mode) and learning using Energy Exchange System (EES) platform. DDM solution provides ability for an AMS to operate in real-world scenarios involving dynamic geometry and changing physical environment. For example, the first component can be an actuator and power train (A&P) system of an autonomous vehicle. The second component can be an autonomous simulation and test (AST) fixture on which a wheel of the autonomous vehicle is mounted, wherein the vehicle AST simulates a road or off-road condition for the autonomous vehicle. In another example, the first component can be a surgical A&P system of a robotic surgical device, and the second component can be a surgical AST that simulates an environment of living tissue.

Image guided surgery includes capturing a primary modality image of a surgical field of a patient with a camera system, obtaining a secondary modality image of the surgical field registered to the primary image, generating a surgical guidance image based at least in part upon the secondary modality image, and projecting the surgical guidance image onto the patient. The surgical guidance image presents visual augmentations on or over the patient to inform a medical practitioner during a surgical procedure.

This application relates to a surgical data acquisition method. In one aspect, the surgical data acquisition method includes acquiring information about movement of a surgical robot, and dividing a hexahedral block including a maximum movement range of the surgical robot into a plurality of sub-blocks of a specified number. The method may also include storing, for each of the plurality of sub-blocks, information on a sub-block corresponding to a position in which the surgical robot has moved and information about the movement of the surgical robot within the sub-block.

A tracker 30 for a Head-Mounted Display, HMD, unit is provided. The tracker 30 comprises a carrier element 10 carrying one or more markers 16a, 16b that are configured to permit determining a position of the tracker 30. The carrier element 10 comprises at least one magnetic element 32 configured to cooperate with at least one magnetic element 22 provided on the HMD unit 62, or on a base element 20 that is to be fixed to the HMD unit 62, for detachably attaching the carrier element 10 to the HMD unit 62.
