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.

Abstract: Disclosed herein are insertion and extraction instruments for orthopaedic procedures that are used for inserting and extracting trials and implants. The instruments include a body extending along a central axis having first and second arms extending from the body along first and second axes. The first and second arms may be moveable with the distal ends of the arms being configured to engage first and second engagement feature of a trial or an implant. The first and second axes define an angle therebetween such that when the distal end of the first arm is received in a first engagement feature of the implant and the distal end of the second arm is in the second engagement feature, the distal ends of the arms are urged against respective first and second side walls of the first and second arms to secure the instrument to the trial or implant.

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.
