There is provided a medical observation apparatus including: a determination unit which determines an apparatus to be used based on a captured image for medical use captured by an imaging device; and a display control unit which causes a related image for medical use corresponding to the determined apparatus and the captured image for medical use to be displayed.

A computer-implemented method to improve the point collection process during registration of a bone for a computer-assisted surgical procedure is provided. Based on bone digitization data, a simulation is performed to confirm the accuracy of the registration for different digitization regions. Results are tested to identify which digitization regions meet a predefined accuracy requirement. The resulting information is used to perform a computer-assisted surgical procedure. A computerized simulation method for registration of a bone for a computer-assisted surgical procedure is also provided based on processor executing random stroking an expected exposed surface of a bone model with multiple of stroke curves to cover most of the bone model surface with uniform noise and a random sample consensus is applied to remove outlying point to yield the best registration results, to find the top subset as to overlap. A method to perform computer-assisted surgery is also provided.

A medical apparatus includes a registration tool, which includes a position sensor, A position-tracking system is configured to acquire position coordinates of the sensor in a first frame of reference defined by the position-tracking system. A processing unit is configured to receive 3D image data with respect to the body of the patient in a second frame of reference, to generate a 2D image of the surface of the patient based on the 3D image data, to render the 2D image to a display screen, and to superimpose onto the 2D image icons indicating locations of respective landmarks. The processing unit receives the position coordinates acquired by the position-tracking system while the registration tool contacts the locations on the patient corresponding to the icons on the display, and registers the first and second frames of reference by comparing the position coordinates to the three-dimensional image data.

The present invention relates to a digital image reality aligning kit, applied to a mixed reality system integrated with a surgical navigation system including: a plurality of moveable markers corresponded to a plurality of moveable marker coordinates respectively and a part of the plurality of moveable markers configured on a surgical instrument; a positioning marker corresponded to a positioning marker coordinate and configured in proximity to a surgical area corresponded to a surgical area coordinate, when the positioning marker is settled, the relative position thereof with respect to the other part of the plurality of moveable markers and the surgical area are determined accordingly, so as to transform the surgical area coordinate to the positioning marker coordinate; and a mixed reality device corresponded to a mixed reality device coordinate and detecting the positioning marker to transform the positioning marker coordinate to the mixed reality device coordinate accordingly, so as to project a surgical area digital image corresponded to a surgical area digital image coordinate onto the surgical area.

In general, devices, systems, and methods for fiducial identification and tracking are provided.

Disclosed is a system for determining a location and configuration of an expandable member. A flexible coil can be provided on a shape changing portion, such as an expandable portion, to measure a signal as the shape changes.

A method may be provided to operate a medical system. First data may be provided for a first 3-dimensional (3D) image scan of an anatomical volume, with the first data identifying a blood vessel node in a first coordinate system for the first 3D image scan. Second data may be provided for a second 3D image scan of the anatomical volume, with the second data identifying the blood vessel node in a second coordinate system for the second 3D image scan. The first and second coordinate systems for the first and second 3D image scans of the anatomical volume may be co-registered using the blood vessel node identified in the first data and in the second data as a fiducial.

A computer-assisted imaging and localization system assists the physician in positioning surgical effecters, such as implants, tools and instruments, within a surgical site in a patient's body. The system displays overlapping images—one image of the surgical site with the patient's anatomy and another image showing the surgical effecter(s). The overlapping image of the surgical effecter(s) is moved over the static image of the anatomy as the implant/instrument is moved. The movement of the surgical effecter(s) is determined in a three-dimensional coordinate system at a home base location in the patient's anatomy, which home base can be moved during the procedure without interrupting the displays of the overlapping images.

Systems and methods for assisting users with accurate tool identification. A tool includes a tool feature, and a navigation system includes a localizer to detect a position of the tool feature. A memory stores identification data associated with a plurality of tools. Controller(s) is/are coupled to the navigation system, the memory and the display. The controller(s) receive, from the localizer, the detected position of the tool feature and compare the detected position of the tool feature with the identification data stored in the memory to determine an identity of the tool. The controller(s) present, on a display, the identity of the tool and an identity of at least one other tool.

A method of repairing a fractured bone may include implanting a prosthetic stem into an intramedullary canal of the fractured bone. First and second bone segments of the fractured bone may be robotically machined to include first and second implant-facing surfaces that are substantially negatives of first and second surface portions of the first end of the prosthetic stem. The first and second tuberosities may be machined so that the first and second bone segments have first and second interlocking surfaces shaped to interlock with each other. During implantation, the first and second implant-facing surfaces are in contact with the first and second surface portions of the first end of the prosthetic stem, and the first interlocking surface interlocks with the second interlocking surface.
