A system for tracking resection planes during a surgical procedure includes a cutting block and a position tracker. The cutting block is configured to be mounted on an anterior surface of a bone during the surgical procedure. The cutting block comprises at least one slot configured to position a resection tool during the surgical procedure. The position tracker is configured to be directly attached to the cutting block after the cutting block is mounted on the anterior surface to allow positional tracking of the cutting block by a tracking device during the surgical procedure.

System and method for tracking resection planes

A cut guide assembly () and a system for mounting assembly on a patient are described. The system includes an ankle clamp (), an alignment guide () configured to be removably attached to the ankle clamp, and the cut guide assembly. The cut guide assembly includes a cut guide () and a position tracker (). The cut guide includes a receiving feature () configured to removably attach to at least a portion of the alignment guide, a locking mechanism () configured to lock the receiving feature to the at least a portion of the alignment guide, and a plurality of pin receptacles (), each of the plurality of pin receptacles configured to receive a bone pin () configured to affix the cut guide to a patient's bone. The position tracker configured to be affixed to the cut guide when the cut guide is affixed to the patient's bone.

Fixation-free robotic surgery

A method and system for updating a bone model for a surgical procedure is provided. The computer system can include a display screen for displaying a GUI that allows a user to define one or more shapes to generate a selected volume of a bone model. The computer system can update the bone model to remove the selected volume as defined by the user. The computer system can display the updated bone model to the user and/or use the updated bone model to guide the surgeon to remove the portions of the patient's bone corresponding to the updated bone model under robotic assistance.

Intraoperative computer-aided design of bone removal based on selected geometric shapes for robotic assisted surgery

Surgical punch tools and methods of using the same are disclosed herein. A surgical punch tool may include a stationary base component having a planar bottom side. The planar bottom side may include one or more posts extending therefrom. Each post may include an associated sharp pin. A movable actuation portion may be configured to move each sharp pin from a non-actuated position within the corresponding post to an actuated position extending through the base component and from the corresponding post.
