Systems and methods for providing assistance to a surgeon for minimizing errors during a surgical procedure are disclosed. A method includes creating a Three-Dimensional (3D) model of a patient using at least one image of an affected area of the patient. Surgical paths are retrieved for performing a surgical procedure. A surgical path, selected by a surgeon, may be displayed as overlaid on the 3D model. A haptic barrier and a hard barrier may be defined for different types of tissues and feedbacks may be associated with the haptic barrier and the hard barrier. Position of a surgical tool of a robotic surgical system may be monitored in real-time during a surgical procedure. Movement of the surgical tool into one of the haptic barrier and the hard barrier may be detected and a suitable feedback may be provided, based on the movement.

In accordance with one embodiment, an automated probe system includes a probe configured to be reversibly inserted into a live body part, a robotic arm attached to the probe and configured to manipulate the probe, a first sensor configured to track movement of the probe during an insertion and a reinsertion of the probe in the live body part, a second sensor configured to track movement of the live body part, and a controller configured to calculate an insertion path of the probe in the live body part based on the tracked movement of the probe during the insertion, and calculate a reinsertion path of the probe based on the calculated insertion path while compensating for the tracked movement of the live body part, and send control commands to the robotic arm to reinsert the probe in the live body part according to the calculated reinsertion path.

A cutting device is provided that includes an expandable tube having a base and a hollow interior for receiving the implant therein. The expandable tube includes cutting segments extending from the base and terminating to form a distal end of the expandable tube. At least one of the cutting segments has a cutting end with cutting teeth at the distal end of the expandable tube. Spring shaped sections are provided that extend the cutting segments. A method for removing an implant from a target bone is also provided based on the cutting device. A system for removing material directly surrounding an outer surface of an implant in an intramedullary canal of a target bone is also provided based on the cutting device and a sheath. A retractable opening is formed of leaflets at a distal end of the sheath, and a proximal end opposite the distal end.

Apparatus, including a guidewire, having a distal end dimensioned to penetrate into a nasal sinus and a balloon, which is fitted over the guidewire in proximity to the distal end. There is an inflation channel, which runs along the guidewire and is coupled to convey a pressurized fluid into the balloon so as to inflate the balloon. The apparatus also includes a first electrode, fixedly attached to a distal tip of the guidewire, and a second electrode, fixedly attached to the guidewire at a location proximal to the distal tip. There are conductive leads running along the guidewire and coupled to apply an electrical potential between the first and second electrodes.

A surgical system includes a first detector that includes a first array of pixels configured to detect light reflected by a surgical instrument and generate a first signal comprising a first dataset representative of a visible image of the surgical instrument. The surgical system also includes a second detector, comprising a second array of pixels configured to detect infrared radiation produced by the surgical instrument during a procedure using the surgical instrument and generate a second signal comprising a second dataset representative of an infrared image of the surgical instrument. The surgical system further includes a processor configured to receive the first and second signals, identify from the first dataset data representative of the surgical instrument, and identify from the second dataset data representative of one or more regions of the surgical instrument above a predetermined threshold temperature. The processor is also configured to generate a modified image of the surgical instrument based on data identified from the first and second dataset. The modified image includes visible indicia in the one or more region of the surgical instrument at or above the predetermined temperature.

An eye tracking system may comprise an image display configured to display a stereo image of a surgical field to a user, a right eye tracker configured to measure data about a first gaze point of a right eye of the user, and a left eye tracker configured to measure data about a second gaze point of a left eye of the user. The eye tracking system may also comprise at least one processor configured to process the data about the first gaze point and the second gaze point to determine a viewing location in the displayed stereo image at which a three-dimensional gaze point of the user is directed.

A system and method for intra-operatively measuring or verifying the placement of an implant within a bone in joint arthroplasty procedures are described herein. Pre-operative bone data of the patient is collected. A user plans the position of one or more implants relative to the pre-operative bone data. Intra-operatively, the patients bone is registered to the pre-operative bone data and to a computer-assist device. The bone is prepared and a physical implant is installed with the bone. A plurality of points are digitized on at least one of the physical implant or an apparatus associated with the physical implant. The computer-assist device calculates any errors between the planned position and orientation (POSE) of the implant relative to the actual POSE of the physical implant using the digitized points. The system may further notify a user of any errors and provide instructions to minimize the errors.

A method for a robotic surgical system includes displaying a graphical user interface on a display to a user, wherein the graphical user interface includes a plurality of reconfigurable display panels, receiving a user input at one or more user input devices, wherein the user input indicates a selection of at least one software application relating to the robotic surgical system, and rendering content from the at least one selected software application among the plurality of reconfigurable display panels.

Haptic feedback from a robotic surgical tool can be adjusted based on intra-operative assessment of the accuracy of a pre-operative surgical navigational plans. Navigational reference points are identified in at least one pre-operative image. At least one haptic response is identified for interactions between at least one robotic surgical tool and at least one navigational reference point. At least one intra-operative image is compared to the pre-operative image to determine the relative position of at least two corresponding navigational reference points in the images. The reference points' relative position determines a confidence level in the accuracy of the pre-operative navigational reference point. The haptic response is adjusted in timing, location, type, or amplitude based upon the confidence level. Tolerances and surgical navigation plan may also be updated and altered based on the confidence level.

End effectors for driving tools at surgical sites along trajectories maintained by surgical robots. A tool has interface and working ends. An end effector has a mount to attach to the surgical robot, and an actuator configured to generate torque. A drive assembly with a geartrain translates rotation from the actuator into rotation of a drive conduit supported about an axis. A rotational lock operatively attached to the drive conduit releasably secures the tool for concurrent rotation about the axis, and an axial lock releasably secures the tool for concurrent translation with the drive conduit along the trajectory maintained by the surgical robot. The axial lock is operable between a release configuration where relative movement between the drive assembly and the tool is permitted along the axis, and a lock configuration where relative movement between the drive assembly and the tool is restricted along the axis.
