  • Publication number: 20240122561
    Abstract: A medical imaging system includes a movable station having a C-arm, a collector, an X-ray beam emitter, and a controller. The collector is attached to a first end of the C-arm. The X-ray beam emitter faces the collector to emit an X-ray beam in a direction of the collector and is attached to a second end of the C-arm. The controller moves one of the X-ray beam emitter and the collector to a first offset position along a lateral axis orthogonal to the arc, and obtains a first set of images by rotating the collector and the X-ray beam emitter along the arc about a scanned volume. The controller moves the one of the X-ray beam emitter and the collector to a second offset position along the lateral axis, and obtains a second set of images. The controller combines the first and second set of images to generate a three-dimensional image of the scanned volume.

  • Publication number: 20240108417
    Abstract: Embodiments consistent with the present disclosure allow the ring, arc, and linear offset values for a stereotactic frame to be determined for a cranial procedure without requiring a CT scan to be acquired with the fiducial frame attached. Having the ring, arc, and offset values available for a cranial procedure allows the surgeon to revert to traditional stereotactic ring-arc frame guidance as a fallback strategy in case a robot cannot be used. This disclosure also provides an alternate method for registering a ring-arc system to the medical image volume for facilities having no CT scanner or scanner with limited field of view such that the intended fiducial localizer cannot be used.

  • Patent number: 11944363
    Abstract: A method for bending a surgical rod using an automated bending system includes receiving an indication of a plurality of line segments defined on the rod and an indication of an angle measurement to be formed between at least two adjacent ones of the plurality of line segments. Bending parameters to perform on the rod to form the angle measurement between the at least two adjacent ones of the plurality of line segments are determined and operation of the automated bending system is controlled using the bending parameters to create an angle having the angle measurement between the at least two adjacent ones of the plurality of line segments.

  • Patent number: 11944325
    Abstract: A system for robotic surgery makes use of an end-effector which has been configured so that a drill connected thereto is guided in its trajectory and limited in its advancement into an associated anatomical feature by a drill guide. The drill guide may be adjusted manually to engage a corresponding surface of the drill after its advancement by a pre-selected amount. The drill guide likewise includes features to guide the drill during trajectories having oblique angles relative to the surface of the anatomical feature associated with the medical procedure.

  • Patent number: 11941814
    Abstract: System and method of more efficiently identifying and segmenting anatomical structures from 2-D cone beam CT images, rather than from reconstructed 3-D volume data, is disclosed. An image processing system receives, from a cone beam CT device, at least one 2-D x-ray image, which is part of a set of x-ray images taken from a 360 degree scan of a patient with a cone beam CT imaging device. The x-ray image contains at least one anatomical structure such as vertebral bodies to be segmented. The received x-ray is then analyzed in order to identify and segment the anatomical structure contained in the x-ray image based on a stored model of anatomical structures. Once the 360 degree spin is completed, a 3-D image volume from the x-ray image set is created. The identification and segmentation information derived from the x-ray image is then added to the created 3-D image volume.

  • Publication number: 20240090884
    Abstract: A surgical robot system includes a robot having a robot base and a robot arm coupled to the robot base, and a surgical retractor. The surgical retractor includes a retractor frame, a coupler, blades, a force and/or torque sensor, and a force and/or torque feedback determination unit. The retractor frame includes arms that are translatably and/or pivotably connected to the retractor frame. The coupler releasably attaches the retractor frame to the robot arm. The blades are each coupled to and extend away from a distal end of one of the arms. The force and/or torque sensor is connected to the blades and indicates an amount of force and/or torque being applied to the blades from contact with material of a surgical site. The force and/or torque feedback determination unit determines the amount of force and/or torque being applied to the blades based on the indication.

  • Publication number: 20240065707
    Abstract: A system of robotic surgery includes components capable of drilling a bore in the cranium of a patient in connection with craniotomy and other cranial surgeries. A perforator associated with such system is controlled by suitable computer-implemented instructions to maintain the perforator tip along a desired trajectory line while moving the perforator bit at locations proximal to such perforator tip in a circular motion, thereby imparting a conical oscillation to the perforator bit relative to the trajectory line. The angle at which the perforator bit is oscillated relative to such trajectory line results in the bore formed in the cranium having a diameter larger than the bit diameter, and the larger diameter and related conical oscillation is selected so as to reduce frictional force opposing withdrawal of the bit from the situs of the bore, thereby reducing the risk of jamming of the bit during its associated operations.

  • Publication number: 20240050158
    Abstract: A surgical implant planning computer positions an implant device relative to a bone of a patient. An initial image of a bone is obtained. An initial location data structure is obtained that contains data defining mapping between locations on the implant device and corresponding locations relative to the bone in the initial image. A target image of the bone of the patient is obtained. A transformation matrix is generated that transforms a contour of a portion of the bone in the initial image to satisfy a defined rule for conforming to a contour of a corresponding portion of the bone in the target image. A transformed location data structure is generated based on applying the transformation matrix to the initial location data structure. A graphical representation of the implant device is displayed overlaid at locations on the target image of the bone determined based on the transformed location data structure.

  • Publication number: 20240020840
    Abstract: System and method of registering a medical image of a patient in an imaging space to the patient in a physical space preferably without the use of any embedded radiopaque fiducials in medical images is provided. In one way, intra-op 2D medical images are used to register a pre-op unregistered 3D medical image. The 2D medical images are registered based on simultaneous tracking of the tracking markers on the imaging device and on the patient by a tracking device at the time of image capture. The 2D images are matched to corresponding simulated 2D images generated from the pre-op 3D image volume. Thus, registration of a pre-op 3D image to the patient is accomplished without performing another 3D scan of the patient.

  • Publication number: 20240016552
    Abstract: A camera tracking system for computer assisted navigation during surgery. The camera tracking system includes a processor operative to receive streams of video frames from tracking cameras which image a plurality of physical objects arranged as a reference array. For each of the physical objects imaged in a sequence of the video frames, that processor determines a set of coordinates for the physical object over the sequence of the video frames. For each of the physical objects, the processor generates an arithmetic combination of the set of coordinates for the physical object. The processor generates an array template identifying coordinates of the physical objects based on the arithmetic combinations of the sets of coordinates for the physical objects, and tracks pose of the physical objects of the reference array over time based on comparison of the array template to the reference array imaged in the streams of video frames.
