Head mounted display assembly with control of head mounted display and loupe position and orientation
Systems, devices, techniques and methods for concurrent use of head mounted displays with surgical loupes during surgical procedures are provided.
1. A system comprising:
a head mounted display (HMD); and
a surgical loupe,
wherein the head mounted display comprises a display unit with a combiner,
wherein the surgical loupe is mounted below the display unit of the head mounted display, and
wherein an eye relief from a back side of the combiner to a front surface of a cornea is the same or smaller than a vertex distance from a back lens of the surgical loupe to the front surface of the cornea.
2. The system of claim 1 , wherein the surgical loupe is attached to the head mounted display, to a head mount, or to a head band.
3. The system of claim 1 , wherein the display unit of the HMD comprises at least one LED display, OLED display, optical element, electronic element, the combiner or combination thereof.
4. The system of claim 1 , wherein the combiner comprises a mirror, a halftone mirror, a curved mirror, a waveguide or combination thereof.
5. The system of claim 1 , wherein the display unit is configured to generate, display, and/or reflect a virtual display.
6. The system of claim 5 , wherein the virtual display is a 2D display, a 3D display, a non-stereoscopic display, a stereoscopic display, or a combination thereof.
7. The system of claim 6 , wherein the virtual display comprises a 2D image of an anatomic structure of a patient, a 3D image of an anatomic structure of a patient, a virtual tool, a virtual instrument, a virtual implant, a virtual device, or a combination thereof.
8. The system of claim 2 , the system further comprising an attachment mechanism, wherein the attachment mechanism is configured to attach the surgical loupe to the head mounted display, the head mount or the head band.
9. The system of claim 8 , wherein the attachment mechanism is configured to move the surgical loupe into at least a first and a second position in relationship to the head mounted display.
10. The system of claim 9 , wherein the first position is configured to facilitate viewing through the surgical loupe, wherein the second position is configured to place the loupe outside the visual field of a user wearing the system.
11. A system comprising:
a head mounted display (HMD); and
a surgical loupe,
wherein the head mounted display comprises a display unit with a left combiner for the left eye and a display unit with a right combiner for the right eye,
wherein the surgical loupe comprises a left surgical loupe for a left eye and a right surgical loupe for a right eye,
wherein the left surgical loupe is mounted below the left eye display unit and the right surgical loupe below the right eye display unit of the head mounted display,
wherein an eye relief from a back side of the left combiner to a front surface of a left cornea is the same or smaller than a vertex distance from a back lens of the left loupe to the front surface of the left cornea, and/or
wherein an eye relief from a back side of the right combiner to the front surface of the right cornea is the same or smaller than a vertex distance from a back lens of the right loupe to the front surface of the right cornea.
12. The system of claim 11 , wherein the left surgical loupe and the right surgical loupe are attached to the head mounted display, to a head mount, or to a head band.
13. The system of claim 11 , wherein each display unit of the HMD comprises at least one LED display, OLED display, optical element, electronic element, or combination thereof.
14. The system of claim 11 , wherein each combiner comprises a mirror, a halftone mirror, a curved mirror, a waveguide or combination thereof.
15. The system of claim 11 , wherein each display unit is configured to generate, display, and/or reflect a virtual display.
16. The system of claim 15 , wherein the virtual display is a 2D display, a 3D display, a non-stereoscopic display, a stereoscopic display, or a combination thereof.
17. The system of claim 16 , wherein the virtual display comprises a 2D image of an anatomic structure of a patient, a 3D image of an anatomic structure of a patient, a virtual tool, a virtual instrument, a virtual implant, a virtual device, or a combination thereof.
18. The system of claim 12 , the system further comprising one or more attachment mechanism, wherein the one or more attachment mechanism is configured to attach the left surgical loupe and the right surgical loupe to the head mounted display, the head mount or the head band.
19. The system of claim 18 , wherein the one or more attachment mechanism is configured to move the left surgical loupe into at least a first and a second position in relationship to the head mounted display, and/or to move the right surgical loupe into at least a first and a second position in relationship to the head mounted display.
20. The system of claim 19 , wherein the first position is configured to facilitate viewing through the left surgical loupe and/or the right surgical loupe, wherein the second position is configured to place the left surgical loupe and/or the right surgical outside the visual field of a user wearing the system.
