Aspects of the present disclosure relate to systems, devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display. Aspects of the present disclosure relate to systems, devices and methods for displaying, placing, fitting, sizing, selecting, aligning, moving a virtual implant on a physical anatomic structure of a patient and, optionally, modifying or changing the displaying, placing, fitting, sizing, selecting, aligning, moving, for example based on kinematic information.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed. The method comprises the steps of gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical instrument, analyzing the gathered data to determine an appropriate operational adjustment of the surgical instrument, and adjusting the operation of the surgical instrument to improve the operation of the surgical instrument.

A surgical instrument comprising a shaft, an end effector, and an articulation joint is disclosed. The end effector is rotatably connected to the shaft about the articulation joint, wherein the end effector is rotatable between a first orientation and a second orientation, wherein the shaft comprises a longitudinal axis and the end effector comprises a tissue gap, wherein the tissue gap faces the longitudinal axis when the end effector is in its first orientation, and wherein the tissue gap extends at an angle relative to the longitudinal axis when the end effector is in its second orientation. The surgical instrument further comprises an articulation drive system configured to articulate the end effector relative to the shaft and a dampener configured to prevent the end effector from being back-driven from its second orientation into its first orientation.

A projection system for projecting medical information onto the surface of the human body such that the medical information conforms and registers to the contour of the underlying shape of the region it is being projected upon. The projection system is in communication with one or more projectors and one or more sensors which capture the topography/area/volume of the region of interest and/or the view of the user, and alter the medical information such that the medical information remains accurate in dimensions when projected into the area of interest.

Apparatus and methods are described including tracking a tool portion and a patient marker from a first line of sight, using a first tracking device disposed upon a first head-mounted device that includes a display. The tool portion and the patient marker are tracked from a second line of sight, using a second tracking device. When a portion of the patient marker and the tool portion are both within the first line of sight, an augmented reality image is generated upon the first display based upon data received from the first tracking device and without using data from the second tracking device. When at least the patient marker portion and the tool portion are not both within the first line of sight, a virtual image of the tool and anatomy of the patient is generated using data received from the second tracking device. Other applications are also described.

An optical scanning imaging/projection apparatus includes a light source that outputs illumination light and projection light in the visible range, an optical scanner that scans the illumination light and the projection light, which are output from the light source, along a predetermined scanning trajectory, a switch that switches the output from the light source so that the illumination light and the projection light are alternately output, an optical detector that detects observation light generated by a subject irradiated with the illumination light, a storage that stores data in which an intensity of the detected observation light detected is associated with information indicating a detection position on the scanning trajectory, and a projection light controller that controls, on the basis of the data stored in the storage unit, an intensity of the projection light to be applied to each position on the scanning trajectory.

The present invention provides a surgical robot system which includes a workstation, a robotic arm, a scanning module, a guiding module and the like. Fast registration may be completed by means of the scanning module. The system improves the speed and accuracy of registration and shortens the period of the operation.

The present invention provides a mobile imaging system for imaging of patients in medical interventions comprising a ring gantry with a plurality of independently rotating rings whereas a first rotating ring positions an X-ray source with collimator and a second rotating ring positions an image detector such that the region of interest (patient) can be positioned off-centered with respect to the ring center. The system supports planar X-ray imaging and Computed Tomography (CT) and Cone beam CT (CBCT) acquisitions of three dimensional (3D) volumes with variable X-ray field of views (FOVs) adapted to regions of interest (ROIs), which are not required to be of cylindrical shape. The mobile system can be equipped with stereoscopic cameras integrated in the gantry an on moving rings to support optical tracking and navigation of instruments within the same co-ordinate system of X-ray information. The gantry can be equipped with additional sensors and robotic manipulators on further rings operating in said co-ordinate system on mobile platform. The gantry provides a generic mechanical and electrical interface to a supporting structure, which can be attached to a variety of mobility platforms to support robotic positioning of the system in various orientations of scanner in treatment rooms to accommodate a wide range of patient setups, including the possibility for inclined and vertical scans of patients in upright position.

A method for guiding electrocardiogram (ECG) electrode placement on a person includes acquiring an image of the person, identifying an externally discernable anatomical landmark on the image, determining target locations for first through nth electrodes as a function of the location of the landmark, and highlighting the target locations on the person. A system for guiding placement of ECG electrodes comprises an imaging device, an illumination source, a processor, and machine readable instructions. The instructions, when executed by the processor, identify at least one marker in an image acquired by the imaging device, determine, as a function of the location of the at least one marker, target locations on the person at which first through nth ECG electrodes should be placed, and cause the illumination source to illuminate the first through nth target locations.

A surgical stapler for stapling the tissue of a patient is disclosed. The surgical stapler comprises a handle, a shaft extending from the handle, and an end effector. The end effector comprises a tissue compression surface, a plurality of staples, and an anvil comprising staple forming pockets, wherein the anvil is movable toward the tissue compression surface during a closing stroke to clamp the patient tissue against and tissue compression surface. The surgical stapler further comprises an anvil closing system configured to move the anvil through the closing stroke, a staple firing system configured to deploy the staples during a staple firing stroke, and means for clamping and holding the patient tissue during the staple firing stroke and moving the end effector relative to the patient tissue after the staple firing stroke.
