A system for performing image-guided surgery includes an instrument having a first portion configured to define a trajectory into the body of a patient, a marker device and a user-interface component. A sensing device receives electromagnetic signals that are reflected or emitted from the marker device, and a processing system, coupled to the sensing device, includes at least one processor configured with processor-executable instructions to perform operations that include tracking the position and orientation of the instrument relative to the patient based on the signals received at the sensing device, receiving a signal from the user-interface component of the instrument indicating a user-input event, and saving the trajectory into the body of the patient defined by the first portion of the instrument in response to receiving the signal.

A multi-axis imaging system comprising an imaging gantry with an imaging axis extending through a bore of the imaging gantry, a support column that supports the imaging gantry on one side of the gantry in a cantilevered manner, and a base that supports the imaging gantry and the support column. The imaging system including a first drive mechanism that translates the gantry in a vertical direction relative to the support column and the base, a second drive mechanism that rotates the gantry with respect to the support column between a first orientation where the imaging axis of the imaging gantry extends in a vertical direction parallel to the support column and a second orientation where the imaging axis of the gantry extends in a horizontal direction parallel with the base, and a third drive mechanism that translates the support column and the gantry in a horizontal direction along the base.

Methods and systems for performing computer-assisted surgery, including robot-assisted image-guided surgery. Embodiments include marker devices for an image guided surgery system, marker systems and arrays for tracking a robotic arm using a motion tracking system, and image guided surgery methods and systems using optical sensors.

A mount assembly for use with a navigable tracker. The mount assembly includes a frame defining a seat, a coupler operatively attached to the frame for releasably securing to the navigable tracker, and a guide defining a bore and arranged in the seat for selective pivoting movement about a pivot point disposed within the bore. An anchor having a shank is arranged for selective sliding engagement with the bore. A guide lock is coupled to the frame and is selectively operable between: a locked configuration to restrict movement of both the anchor and the guide relative to the frame, and a released configuration to simultaneously permit pivoting movement of the anchor relative to the frame about the pivot point and translational movement of the anchor relative to the guide through the bore.

An imaging system includes a first portion and a second portion that translates and/or rotates with respect to the first portion. A first locking mechanism may prevent the second portion from translating with respect to the first portion, such as during transport of the system. A second locking mechanism may prevent the second portion from rotating with respect to the first portion, such as during transport and/or during an imaging scan. Further embodiments include a cable management system between the first and second portions, a spherically-shaped surface of a support gimbal and a user interface device for an imaging system.

A surgical navigation tracker assembly including a rotational adapter for removably attaching a tracker to a surgical instrument assembly including a surgical handpiece. The adapter may be coupled to an end effector of the surgical instrument and configured to allow the end effector to actuate relative to the adapter. The end effector may comprise a stop, the adapter configured to abut the stop when coupled to the end effector. The adapter may comprise a mount for releasably securing the tracker to the adapter. The adapter may also comprise a biasing element, and the biasing element may comprise an abutment interface configured to engage either of the surgical handpiece or the stop when the end effector is coupled to the surgical handpiece. The biasing element is configured to limit rotation of the adapter relative to the surgical handpiece when the abutment interface is engaged with the surgical handpiece or the stop.

A robotic surgical system is provided. The robotic surgical system includes a navigation system and a robotic arm. The robotic arm includes a joint including a proximal joint subassembly supporting a distal joint subassembly for rotation about an axis. The joint also includes a distal joint module attached to the distal joint subassembly and including a distal interface. The robotic arm also includes a proximal joint module attached to the proximal joint subassembly and including a proximal interface. The robotic arm also includes a harness assembly coupled to the proximal interface and to the distal interface, and a spiral region being supported for movement between an expanded state and a contracted state to permit rotation of the distal joint subassembly between a first radial position and a second radial position while maintaining communication between the proximal interface and the distal interface.

A mount assembly for use with a navigable tracker. The mount assembly includes a frame, a coupler for releasably securing the tracker, and an anchor extending along an axis between a distal end for engaging tissue and a proximal end arranged to receive impaction force. The anchor includes an arrow body coupled to a shank and having a tip tapering towards the distal end for advancing into engagement with tissue, and a pair of wing braces to inhibit rotation of the anchor relative to engaged tissue. A guide operatively attached to the frame defines a bore to receive the shank, and a guide lock is operable between: a released configuration to permit movement of the shank along the bore, and a locked configuration to restrict movement of the shank along the bore to effect concurrent movement of the tracker with the tissue engaged by the anchor.

A table system for use with an imaging device includes a base portion that supports the table system over a support surface, a patient support including a platform for supporting a patient in a standing position and a bed for supporting the patient in a lying position, a linkage portion coupled between the base portion and the patient support that is pivotable with respect to both the base portion and the patient support, a first drive mechanism that drives the pivoting of the patient support with respect to the linkage portion, and a second drive mechanism that drives the pivoting of the linkage portion with respect to the base portion, the first and second drive mechanisms moving the patient support between a vertical position in which the platform is substantially parallel to the support surface and a horizontal position in which the bed is substantially parallel to the support surface.
