A method and system are provided to assist in positioning the field-of-view (FOV) of an optical tracking system during a computer-assisted surgical procedure. The method includes displaying a view from a visible light detector on a display, and generating an outline as an overlay on the display of a FOV of two or more optical tracking detectors on the displayed view from the visible light detector. A user then positions at least one of: a) the two or more optical tracking detectors, or b) a tracked object based on the displayed view from the visible light detector and the generated outline.

A passive end effector of a surgical system includes a base connected to a rotational disk, and a saw attachment connected to the rotational disk. The base is attached to an end effector coupler of a robot arm positioned by a surgical robot, and includes a base arm extending away from the end effector coupler. The rotational disk is rotatably connected to the base arm and rotates about a first location on the rotational disk relative to the base arm. The saw attachment is rotatably connected to the rotational disk and rotates about a second location on the rotational disk. The first location on the rotational disk is spaced apart from the second location on the rotational disk. The saw attachment is configured to connect to a surgical saw including a saw blade configured to oscillate for cutting. The saw attachment rotates about the rotational disk and the rotational disk rotates about the base arm to constrain cutting of the saw blade to a range of movement along arcuate paths within a cutting plane.

A device for providing joint replacement robotic surgery information comprises: a memory unit configured to store surgery plan information set before surgery including a cutting path of a surgical target bone; a target acquisition unit configured to acquire positions of a plurality of cutting target points forming the cutting path based on the surgery plan information; a robot position calculation unit configured to calculate a current cutting position of the surgical robot among the cutting target points based on surgery progress of the surgical robot; a graphic user interface (GUI) providing unit configured to generate graphics that represent surgery progress information including a current cutting position of the surgical robot and positions of the cutting target points on a virtual bone model corresponding to the surgical target bone; and a display unit configured to display the virtual bone model and the surgery progress information.

A surgical system for computer assisted navigation during surgery, includes at least one processor that obtains a 3D radiological representation of a targeted anatomical structure of a patient and a set of fiducials of a registration fixture. The operations attempt to register locations of the set of fiducials in the 3D radiological representation to a 3D imaging space tracked by a camera tracking system. Based on determining one of the fiducials of the set has a location that was not successfully registered to the 3D imaging space, the operations display at least one view of the 3D radiological representation with a graphical overlay indicating the fiducial has not been successfully registered to the 3D imaging space, receive user-supplied location information identifying where the fiducial is located in the 3D radiological representation, and register the location of the fiducial to the 3D imaging space based on the user-supplied location information.

A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to heat tissue to create lesions without ablating the tissue. The system includes a first treatment device having at least one electrode for applying radiofrequency energy to tissue, a controller including a connector to which a first treatment device is coupled for use, and a generator for applying radiofrequency energy to the electrodes. The controller controls application of energy so that the tissue is thermally treated to create lesions but preventing thermal treatment beyond a threshold which would ablate the tissue.

A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to treat tissue to create lesions without ablating the tissue. The system includes a first treatment device having a plurality of electrodes. The electrodes are maintained in axial alignment and fixed radial spacing in retracted and extended positions. The device includes a basket having a plurality of arms. The arms are maintained in a fixed radial spacing in the collapsed position of the basket.

A system includes a uterine manipulator having a shaft. The uterine manipulator is coupled with a robotic arm. An imaging instrument is operable to provide an image of an exterior of the uterus of the patient. A user input feature is configured to transition between an engaged state and a non-engaged state. In the engaged state, the user input feature is operable to control movement of the robotic arm to thereby drive movement of the uterine manipulator. A console includes a display screen and is configured to provide a view from the imaging instrument of the exterior of the uterus of the patient, on the display screen. The console is further configured to provide an indicator on the view from the imaging instrument, on the display screen, the indicator indicating whether the user input feature is in the engaged state or the non-engaged state.

Transducer-based systems can be configured to display a graphical representation of a transducer-based device, the graphical representation including graphical elements corresponding to transducers of the transducer-based device, and also including between graphical elements respectively associated with a set of the transducers and respectively associated with a region of space between the transducers of the transducer-based device. Selection of graphical elements and/or between graphical elements can cause activation of the set of transducers associated with the selected elements. Selection of a plurality of graphical elements and/or between graphical elements can cause visual display of a corresponding activation path in the graphical representation. Visual characteristics of graphical elements and between graphical elements can change based on an activation-status of the corresponding transducers. Activation requests for a set of transducers can be denied if it is determined that a transducer in the set of transducers is unacceptable for activation.

A system for recording or recalling ablation information includes a workstation, and control circuitry. The workstation may include a display, a user input device, and a memory. The workstation may be configured to be in electrical communication with an ablation device. The control circuitry may be in electrical communication with the ablation device and the memory. The control circuitry may be configured to receive input associated with an ablation procedure performed by the ablation device, and associate the input with an anatomical structure of the patient.

A computer-implemented method for creating an activity-optimized cutting guides for surgical procedures includes receiving one or more pre-operative images depicting one or more anatomical joints of a patient, and creating a three-dimensional anatomical model of the one or more anatomical joints based on the one or more pre-operative images. One or more patient-specific anatomical measurements are determined based on the three-dimensional anatomical model. A statistical model of joint performance is applied to the patient-specific anatomical measurements to identify one or more cut angles for performing a surgical procedure. A patient-specific cutting guide is created that comprises one or more apertures positioned based on the one or more cut angles.
