Abstract

A system for displaying an intraoperative user interface for a surgical procedure is disclosed. The system comprises an arthroscopic imaging device, a display device, an input device, a processor, and a non-transitory, computer-readable medium. The arthroscopic imaging device is configured to capture one or more images of a patient anatomy within a joint of a patient. The input device is configured to receive input from a user. The processor is configured to receive the images from the arthroscopic imaging device and display a user interface on the display device that includes the images from the arthroscopic imaging device. The processor is also configured to receive the input from the input device, display one or more visual overlays over the one or more images based on the input, and apply one or more digital markers in a fixed location on the one or more images based on the input.

First claim

What is claimed is:

1. A system for displaying an intraoperative user interface for a surgical procedure, the system comprising:
an arthroscopic imaging device configured to capture one or more images of a patient anatomy within a joint of a patient;
a display device;
an input device configured to receive input from a user;
a processor; and
a non-transitory, computer-readable medium storing instructions that, when executed, cause the processor to:
receive the one or more images from the arthroscopic imaging device,
display, on the display device, a user interface including the one or more images,
receive the input from the user,
display one or more visual overlays over the one or more images based on the input, and
apply one or more digital markers in a fixed location on the one or more images,

wherein the system further comprises a marking unit configured to create an artificial marking on the patient anatomy within the joint of the patient,
wherein the instructions, when executed, further cause the processor to:
receive marking input that indicates a desired location with respect to the one or more images for placement on the patient anatomy within the joint of the patient of the artificial marking,
responsive to receiving the marking input, cause to apply, by the marking unit, the artificial marking to the patient anatomy at the desired location within the joint of the patient based on the marking input, and
detect and track the artificial marking caused to be applied by the marking unit at the desired location, using one of the one or more digital markers applied to the one or more images, even as a field of view of the arthroscopic imaging device is shifted.

2. The system of claim 1 , wherein the marking unit comprises a drill and the artificial marking comprises a drilled hole.

3. The system of claim 1 , wherein the marking unit comprises a curette and the artificial marking comprises a curetted divot.

4. The system of claim 1 , wherein the marking unit comprise one of a radio frequency energy unit and a heat energy unit, wherein the artificial marking comprises a discoloration of a tissue of the patient anatomy.

5. The system of claim 1 , wherein the marking unit comprise a dye-applying unit, wherein the artificial marking comprises a discoloration of a tissue of the patient anatomy.
