Abstract

An illuminating ring assembly is disclosed. The illuminating ring configured to be used with a surgical access element. The illuminating ring assembly comprises a housing defined by a cover and a wall member extending from the cover, wherein the cover and wall member cooperate to define a cavity therein, a light element configured to be disposed with the cavity, and an attachment mechanism configured to selectively attach the housing to a surgical access element. Wherein the cover and the light element both include an opening therethrough.

Claims

1. An illuminating ring assembly configured to be used with a surgical access element, comprising:

a housing defined by a cover and a wall member extending from the cover, wherein the cover and the wall member cooperate to define a cavity therein;

an illumination ring disposed within the cavity, wherein the cover includes a cover opening therethrough and the illumination ring includes an illuminating ring opening therethrough, the cover opening and the illumination opening being aligned and configured to receive medical instruments therethrough; and

an attachment mechanism selectively attached to the housing and to a surgical access element having a sheath that defines a sheath opening therethrough such that the sheath opening aligns with the openings of the illumination ring and the cover, the attachment mechanism further comprises a hinged clamp member having two arms that are joined together by a hinge, wherein ends of each arm are configured to move together and lock together and engage a portion of the housing to positively secure the attachment mechanism to the housing.

2. The illuminating ring assembly of claim 1, wherein the ends of each arm are configured to lock together around a protuberance extending from an end face of the housing.

3. The illuminating ring assembly of claim 1, wherein an outer surface of the cover further includes at least one retaining notch therein, wherein the retaining notch extends from an outer periphery of the cover to a peripheral edge of the opening formed in the cover.

4. The illuminating ring assembly of claim 3, wherein an inner perimeter of the cover includes a beveled entry surface, and wherein the cover includes a plurality of retaining notches and wherein each retaining notch extends to the beveled entry surface.

5. The illuminating ring assembly of claim 4, wherein the beveled entry surface further includes inner notches aligned with retaining notches of the cover, wherein the inner notches extend into the opening of an inner ring of the cover.

6. The illuminating ring assembly of claim 5, wherein the inner notches are configured to taper inwardly to a V-shape at the inner ring of the cover.

7. The illuminating ring assembly of claim 1, further comprising at least one retaining projection extending outwardly away from the wall member of the housing, wherein each retaining projection is configured with a hole extending through the projection.

8. The illuminating ring assembly of claim 1, further comprising at least one retaining projection extending from the cover configured to cooperate with a retaining mechanism to secure the cover to a surface.

9. The illuminating ring assembly of claim 1, wherein the housing further comprises a securing member extending from a bottom edge of the housing, wherein the attachment mechanism is configured to grip the securing member when the ends of each arm are locked together.

10. The illuminating ring assembly of claim 9, wherein ends of each arm are configured with complementary depressions and wherein the depressions are oriented toward one another when arms are locked together so as to define a securing hole that accepts the securing member.

11. The illuminating ring assembly of claim 1, wherein the housing further comprises a positioning member extending from a bottom edge of the housing, wherein the positioning member is received within a mounting cavity formed on the attachment mechanism, when the attachment mechanism is mounted to the housing.

12. The illuminating ring assembly of claim 11, wherein the mounting cavity is positioned in the hinge.

13. The illuminating ring assembly of claim 1, wherein the cover further includes at least one manipulation opening positioned between the cover opening and an outer periphery of the cover.

14. The illuminating ring assembly of claim 13, wherein the cover further includes a plurality of manipulation openings spaced equidistantly from one another.

15. A surgical access kit, comprising an illuminating ring assembly and a surgical access element, wherein the illuminating ring assembly comprises:

a housing defined by a cover and a wall member extending from the cover, wherein the cover and the wall member cooperate to define a cavity therein;

an illumination ring disposed within the cavity, wherein the cover and the illumination ring both include aligned openings therethrough configured to receive medical instruments therethrough; and

an attachment mechanism configured to selectively attach the housing to a surgical access element, the attachment mechanism further comprises a hinged clamp member having two arms that are joined together by a hinge, wherein ends of each arm are configured to move together and lock together and engage a portion of the housing to positively secure the attachment mechanism to the housing;

wherein the surgical access assembly comprises an elongated sheath with a grip ring thereon, wherein the attachment mechanism engages a portion of the grip ring to secure the illumination ring assembly to the grip ring.

16. The surgical access kit of claim 15, wherein the grip ring further comprises a locating member that is received within a locking member recess formed on the attachment mechanism.

17. The surgical access kit of claim 16, wherein the locking member recess is formed from complementary grooves on the ends of the arms of the attachment mechanism.
