Abstract

A system includes a display device and an actuated structure mounted to the display device and configured to move the display device in three-dimensional space. The system includes an imaging device configured to capture images of a patient's eye during an ophthalmic surgery and display the images on the display device. A controller is configured to activate the actuated structure to maintain visibility of the display device to a surgeon performing the ophthalmic surgery. The display may be positioned based on a surgeon profile and/or a treatment plan. Whether the display is visible may be determined based on images from a camera mounted to the imaging device, the display device, or elsewhere. Whether the display is visible may be determined based on kinematic data for the actuated structure and/or a support for the imaging device.

First claim

What is claimed is:

1 . A system comprising:
a display device; an actuated structure mounted to the display device and configured to move the display device in three-dimensional space; an imaging device configured to capture images of a patient's eye during an ophthalmic surgery and display the images on the display device; and a controller configured to activate the actuated structure to maintain the display device in a field of view of a surgeon performing the ophthalmic surgery.

2 . The system of claim 1 , wherein the imaging device is an ophthalmic microscope.

3 . The system of claim 1 , wherein the imaging device is a stereoscopic ophthalmic microscope.

4 . The system of claim 3 , wherein the display device is a three-dimensional display device and the controller is configured to activate the actuated structure to maintain an orientation and distance of the display device relative to the surgeon to enable three-dimensional perception by the surgeon.

5 . The system of claim 1 , wherein the controller is configured to activate the actuated structure to maintain the display device in the field of view of the surgeon performing the ophthalmic surgery by:
receiving a surgeon profile; selecting a position and orientation of the display device according to the surgeon profile; and activating the actuated structure to achieve the position and orientation.

6 . The system of claim 1 , wherein the controller is configured to activate the actuated structure to maintain the display device in the field of view of the surgeon performing the ophthalmic surgery by:
receiving a treatment plan for the ophthalmic surgery; selecting a position and orientation of the display device according to the treatment plan; and activating the actuated structure to achieve the position and orientation.

7 . The system of claim 6 , wherein the treatment plan specifies a surgeon position selected from superior, left temporal, and right temporal; and
wherein the controller is further configured to select the position and orientation of the display device such that the display device is visible from the surgeon position in the treatment plan.

8 . The system of claim 7 , wherein the controller is further configured to select a height of the display device according to a surgeon profile of the surgeon.

9 . The system of claim 1 , wherein the actuated structure is a robotic arm having at least 5 degrees of freedom.

10 . The system of claim 1 , wherein the controller is configured to activate the actuated structure to maintain the display device in the field of view of the surgeon performing the ophthalmic surgery by:
receive one or more inputs including at least one of:
one or more first camera images received from one or more first cameras mounted to the imaging device;
one or more second camera images received from one or more second cameras mounted to the display device;
one or more third camera images received from one or more second cameras mounted in an operating room including the imaging device an the display device;
first kinematic data for the actuated structure; or
second kinematic data for a support for the imaging device; and
select a position and orientation for the display device based on the one or more inputs; and activate the actuated structure to move the display device to the position and orientation.

11 . A system comprising:
a display device; an actuated structure mounted to the display device and configured to move the display device in three-dimensional space; an imaging device configured to capture surgical images of a patient's eye during an ophthalmic surgery and display the surgical images on the display device; a camera mounted to the imaging device; and a controller configured to:
receive camera images from the camera;
evaluate representations of the display device in the camera images; and
activate the actuated structure to maintain the display device unobstructed in a field of view of a surgeon performing the ophthalmic surgery based on the representations of the display device.

12 . The system of claim 11 , wherein the imaging device is an ophthalmic microscope.

13 . The system of claim 11 , wherein the imaging device is a stereoscopic ophthalmic microscope.

14 . The system of claim 13 , wherein the display device is a three-dimensional display device and the controller is configured to activate the actuated structure to maintain an orientation and distance of the display device relative to the surgeon to enable three-dimensional perception by the surgeon.

15 . The system of claim 11 , wherein the controller is further configured to activate the actuated structure to maintain visibility of the display device to the surgeon performing the ophthalmic surgery by:
receiving a surgeon profile; selecting a position and orientation of the display device according to the surgeon profile; and activating the actuated structure to achieve the position and orientation.

16 . The system of claim 11 , wherein the controller is configured to activate the actuated structure to maintain the display device in the field of view of the surgeon performing the ophthalmic surgery by:
receiving a treatment plan for the ophthalmic surgery; selecting a position and orientation of the display device according to the treatment plan; and activating the actuated structure to achieve the position and orientation.

17 . The system of claim 16 , wherein the treatment plan specifies a surgeon position selected from superior, left temporal, and right temporal; and
wherein the controller is further configured to select the position and orientation of the display device such that the display device is visible from the surgeon position in the treatment plan.

18 . The system of claim 17 , wherein the controller is further configured to select a height of the display device according to a surgeon profile of the surgeon.

19 . The system of claim 11 , wherein the actuated structure is a robotic arm.

20 . The system of claim 11 , wherein the actuated structure is a robotic arm having at least 5 degrees of freedom.
