Surgical Systems And Methods For Facilitating Ad-Hoc Intraoperative Planning Of Surgical Procedures

Abstract:

A surgical system, method and CAD program are provided for facilitating surgical planning. A digitization device has a pointer tip and one or more control inputs. A navigation system tracks the digitization device. The CAD program generates a virtual reference frame and receives the tracked state of the digitization device from the navigation system. The CAD program renders, within the virtual reference frame, a virtual representation of the pointer tip of the digitization device having a pose of the pointer tip derived from its tracked state. In response to actuation of the control input(s) of the digitization device, the CAD program registers local virtual reference(s) within the virtual reference frame at a location relative to the pose of the virtual representation of the pointer tip and enables arrangement of geometrical design object(s) within the virtual reference frame relative to the registered local virtual reference(s) to facilitate surgical planning.
