A method for improving the development of an initial surgical plan includes receiving input information, developing an initial surgical plan based upon the input information, and allowing a user to customize the initial surgical plan by providing input related to modifications to the initial surgical plan. The method further includes storing information related to the modifications to the initial surgical plan and using the stored information to develop a subsequent initial surgical plan based on the modifications.

Surgical planning guidance and learning

Femoral implant component

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.

Femoral component for bone conservation

A method includes providing a distraction device, and providing, separate from the distraction device, a disposable force sensor pod configured to be removably coupled to the distraction device. The method also includes communicating, by the disposable force sensor pod, information relating to distraction of a joint by the distraction device to a computing system.

A method includes storing a cloud of points reached by a cutting tool during a first stage of modifying a bone with the cutting tool, generating a surface based on the cloud of points, generating a plan for a second stage of modifying the bone with the cutting tool based on a location or rotation of the surface, and using the plan to assist the cutting tool in executing the second stage of modifying the bone.

Systems and methods for adaptive planning and control of a surgical tool

A method for preoperatively characterizing an individual patients biomechanic function in preparation of implanting a prosthesis is provided. The method includes subjecting a patient to various activities, recording relative positions of anatomy during said various activities, measuring force environments responsive to said patient's anatomy and affected area during said various activities, characterizing the patient's biomechanic function from said relative positions and corresponding force environments, inputting the measured force environments, relative positions of knee anatomy, and patient's biomechanic function characterization into one or more computer simulation models, inputting a computer model of the prosthesis into said one or more computer simulation models, and manipulating the placement of the prosthesis in the computer simulation using said patient's biomechanic function characterization and said computer model of the prosthesis to approximate a preferred biomechanical fit of the prosthesis.

Operatively tuning implants for increased performance

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.

System and method for preparing bone

A method of operating a surgical system includes controlling a robotic arm in a first control mode in which the robotic arm constrains movement of a surgical tool coupled to the robotic arm to a virtual geometry correlated with an anatomical feature, switching, responsive to the surgical tool crossing an exit boundary, from the first control mode to a second control mode, and controlling the robotic arm in the second control mode in which movement of the surgical tool is unconstrained by the virtual geometry.

Display screen or portion thereof with graphical user interface

A joint distraction lever includes a lever body having a handle portion coupled to a working portion, a fulcrum extending from a bottom surface of the working portion of the lever body, a distal tip, which is raised above a top surface of the working portion of the lever body, a force measurement device used to measure a distraction force applied at the distal tip during a distraction procedure for a joint during which a torque is applied at the handle portion of the lever body, and a force value output used to indicate the distraction force applied at the distal tip.

A surgical saw assembly that is adapted for cutting an anatomy. The surgical saw assembly includes a blade guard that supports a saw blade prevent deflection or skiving of the saw blade. The blade guard is rotatably moveable and has a front edge profile that interacts with a surface of the anatomy. The front edge profile has a geometry that is at least partially curved and/or follows a non-linear path of movement to provide a smooth interaction between the blade guard and the surface of the anatomy during rotational cuts that are not directly normal to the anatomical surface.

Aspects of the disclosure may involve a method of generating resection plane data for use in planning an arthroplasty procedure on a patient bone. The method may include: obtaining patient data associated with at least a portion of the patient bone, the patient data captured using a medical imaging machine; generating a three-dimensional patient bone model from the patient data, the patient bone model including a polygonal surface mesh; identifying a location of a posterior point on the polygonal surface mesh; creating a three-dimensional shape centered at or near the location; identifying a most posterior vertex of all vertices of the polygonal surface mesh that may be enclosed by the three-dimensional shape; using the most posterior vertex as a factor for determining a posterior resection depth; and generating resection data using the posterior resection depth, the resection data configured to be utilized by a navigation system during the arthroplasty procedure.

Preoperative planning and associated intraoperative registration for a surgical system

Surgical systems and methods for use with a hand-guided tool. The surgical system includes a robotic manipulator that holds a tool guide. The tool guide receives and guides the surgical tool to enable the tool to manipulate a bone. The robotic manipulator autonomously aligns the tool guide to a target orientation relative to the bone. The tool guide is moved to an initial location adjacent to the bone while remaining aligned with the target orientation. The initial location is suitable for the tool to perform an initial manipulation of the bone. The robotic manipulator facilitates withdrawal of the tool guide away from the initial location to a spaced location after the initial manipulation of the bone while maintaining alignment of the tool guide with the target orientation at the spaced guide location. The spaced guide location is suitable for the tool to perform a further manipulation of the bone.
