  • Publication number: 20240108419
    Abstract: A method includes generating a surgical plan for installation of a structure at a bone and controlling a controllable guide structure to guide a cutting tool to sculpt the bone and the structure based on the surgical plan. Sculpting the bone provides the bone with a bone mating surface and sculpting the structure provides the structure with a structure mating surface. The method also includes installing the structure on the bone by engaging the structure mating surface of the structure with the bone mating surface of the bone.

  • Publication number: 20240081940
    Abstract: Systems, methods and computer-program products are provided for aiding in positioning between a surgical object and a machine vision camera in a surgical environment. The machine vision camera senses a position and orientation of a surgical object in its field of view. Controller(s) virtually define a zone within the field of view that indicates a range of acceptable positions for the surgical object relative to a position of the machine vision camera. The controller(s) obtain an acceptable orientation range for the surgical object relative to an orientation of the machine vision camera. The controller(s) execute a GUI to simultaneously present, on the display device, representations of: the field of view; the zone within the field of view; the position of the surgical object relative to the zone; and a current angle difference between the surgical object and the machine vision camera.

    Abstract: Various types of travel bags are provided with at least one portable self-contained vacuum compression system having a portable vacuum pump powered by a portable, preferably removable, rechargeable battery, a compression connection system, and a vacuum compression bag secured within the interior space of the travel bag. The portable self-contained vacuum compression system allows the user to pack more clothing or compressible goods into their travel bag via the use of vacuum compression. The air inside the compression bag can be evacuated by the attached self-contained vacuum pump assembly which is secured within the travel bag in a manner to hold the self-contained vacuum system within the travel bag's internal dimensions in one embodiment. The vacuum compression system can be held in place via a removable or a fixed frame that permits operation of the vacuum compression system within the internal dimensions of the travel bag.

  • Publication number: 20240008992
    Abstract: A femoral prosthetic component includes a patellar guide portion, a pair of condyles projecting from the guide portion and forming an intercondylar notch therebetween, a bearing surface, and an interface surface configured to face a resected surface of a femur. The interface surface comprises an anterior face and a posterior face, and is substantially contoured between the anterior and posterior face to match a contoured surface of the femur. The substantially contoured interface surface may include at least one planar surface portion to about a flat cut portion in the surface of the femur. This planar surface portion may be a distal flat at a distal face of the interface surface. The contoured interface surface may alternatively include a plurality of planar surface portions. The femoral prosthetic component is configured such that preparation of the bone to match the interface surface results in minimal resection of the distal femur.

  • Patent number: 11864957
    Abstract: Systems, methods and software are provided for aiding in positioning of objects in a surgical environment. A tracker is rigidly affixed to a surgical object. A camera has a field of view and senses positions of the tracker in the field of view. Controller(s) provide a zone positioned within the field of view at a location that is static relative to the field of view such that the zone is located independent of the sensed positions of the tracker. The zone defines a range of acceptable positions for the tracker relative to a position of the camera. Controller(s) acquire positions of the tracker as the surgical object is moved throughout a range of motion and enable evaluation of the positions of the tracker throughout the range of motion relative to the zone to aid in positioning of one or more of: the camera, the tracker, or the surgical object.

  • Publication number: 20230114040
    Abstract: Surgical systems, computer-implemented methods, and software programs for generating a milling path for a bone. The implementations involve obtaining a virtual model of the bone, a resection volume defined relative to the virtual model of the bone, and a reference guide defined with respect to the resection volume. Section planes are successively arranged along the reference guide, and each section plane intersects the reference guide and intersects the resection volume. A section path is generated within each section plane and is defined relative to the resection volume. Transition segments are generated to connect section paths of section planes. The milling path is then generated by combining the section paths and the transition segments.

  • Patent number: 11564749
    Abstract: Systems, methods, software and techniques for generating a milling path for a tool of a surgical system are provided. The milling path is designed to remove a resection volume associated with an anatomical volume. A reference guide is defined with respect to the resection volume. Sections are defined along the reference guide in succession. Each section intersects the reference guide at a different intersection point and is at a specified orientation relative to the reference guide at the intersection point. Each section further intersects the resection volume. A section path is generated to be bounded within each section and defined relative to the resection volume. A plurality of transition segments are generated and each transition segment connects section paths of successive sections along the reference guide.

  • Publication number: 20220257334
    Abstract: A clamp assembly fixes a navigation tracker to a bone. The assembly includes first and second clamp jaws. The second clamp jaw is pivotal about a first fixed pivot. A linear driver includes a shaft. A first linkage is pivotal at one end about a second fixed pivot and coupled at an opposing end to the shaft at a first moving pivot. A second linkage is coupled at one end to the shaft at the first moving pivot and coupled at the other end to the second clamp jaw at a second moving pivot. The linear driver linearly translates the shaft to apply force to the first moving pivot in a first direction to pivot the second clamp jaw towards the first clamp jaw and in a second direction opposite to the first direction to pivot the second clamp jaw away from the first clamp jaw.
