1. A surgical port comprising:
- a collar section comprising a first surface positioned to abut a patient'"'"'s skin when the surgical port is in use;
an optical coupler to couple to a light conduit;
a passage section extending from the collar section, the passage section further comprising;
an outer surface;
an inner surface at least partially defining a passage from a first end of the surgical port to a second end of the surgical port;
an illuminator section comprising one or more features configured to direct light from the surgical port into the passage;
wherein the passage section is configured to act as an optical light guide to propagate light received from the light conduit to the illuminator section via internal reflection.

Abstract
The disclosure describes embodiments of systems and methods for surgical illumination, particularly for spinal procedures. Embodiments of the system comprise a surgical port that acts as an optical guide to guide light from an illumination conduit to an illuminator section. The illuminator section can be configured to direct light into a passage to illuminate a target area.

14. A spinal surgical system comprising:
-
an illumination source; a light conduit coupled to the illumination source; a surgical port comprising; a collar section comprising a first surface positioned to abut a patient'"'"'s skin when the surgical port is in use; an optical coupler to couple to the light conduit; a passage section extending from the collar section in a direction to extend into the patient'"'"'s body during use, the passage section further comprising; an outer surface; an inner surface at least partially defining a passage from a first end of the surgical port to a second end of the surgical port; and an illuminator section comprising one or more features configured to direct light onto one or more spinal features when the surgical port is inserted in the patient; wherein the passage section is configured to act as an optical light guide to propagate light received from the light conduit to the illuminator section via internal reflection; a surgical assist mechanism coupled to the collar section of the surgical port. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A method for minimally invasive spinal surgery comprising:
-
creating an incision in a patient; attaching a guide wire to the patient proximate to a target area for a spinal procedure; guiding a first dilator along the guide wire to widen a channel to the target area; guiding a set of sequentially larger dilators on the outside of previously inserted dilators until the channel is a desired size; inserting a surgical port into the incision on the outside of the largest dilator from the set of sequentially larger dilators, wherein the surgical port comprises; a collar section comprising a first surface positioned to abut a patient'"'"'s skin when the surgical port is in place; an optical coupler to couple to a light conduit; a passage section extending from the collar section, the passage section further comprising; an outer surface; an inner surface at least partially defining a passage from a first end of the surgical port to a second end of the surgical port; an illuminator section comprising one or more features configured to direct light from the surgical port into the passage; wherein the passage section is configured to act as an optical light guide to propagate light received from the light conduit to the illuminator section via internal reflection; removing the first dilator and set of sequentially larger dilators from the patient; and illuminating the target area with light from the surgical port. - View Dependent Claims (28, 29, 30, 31)
