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

A computer-assisted method for facilitating surgical planning using a surgical system, the surgical system including a digitization device comprising a pointer tip and one or more control inputs, a navigation system, and a computing device coupled to the navigation system and comprising one or more processors and a non-transitory computer-readable medium having stored thereon a computer-aided design (CAD) program being executable by the one or more processor, the computer-assisted method comprising:

• tracking a state of the digitization device with the navigation system;
• generating a virtual reference frame with the CAD program;
• receiving, with the CAD program, the tracked state of the digitization device from the navigation system;
• rendering, with the CAD program and 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 the tracked state of the digitization device;
• registering, with the CAD program and in response to actuating the one or more control inputs of the digitization device, one or more local virtual references within the virtual reference frame at a location relative to the pose of the virtual representation of the pointer tip;
• and
• enabling, with the CAD program and in response to actuating the one or more control inputs of the digitization device, arrangement of one or more geometrical design objects within the virtual reference frame relative to the one or more registered local virtual references for facilitating surgical planning.

A non-transitory computer-readable medium having stored thereon a computer-aided design (CAD) program being configured to facilitate surgical planning, the CAD program configured to be utilized with a surgical system including a digitization device comprising a pointer tip and one or more control inputs and a navigation system configured to track a state of the digitization device, the CAD program when executed by one or more processors is configured to:

• generate a virtual reference frame;
• receive the tracked state of the digitization device from the navigation system;
• render, 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 the tracked state of the digitization device;
• in response to actuation of the one or more control inputs of the digitization device, register one or more local virtual references within the virtual reference frame at a location relative to the pose of the virtual representation of the pointer tip;
• and
• in response to actuation of the one or more control inputs of the digitization device, enable arrangement of one or more geometrical design objects within the virtual reference frame relative to the one or more registered local virtual references to facilitate surgical planning.
