Abstract

A surgical camera assembly includes an elongated tubular member and a surgical camera. The elongated tubular member includes a lumen extending therethrough that is configured to permit passage of a surgical instrument. The surgical camera is rotatably coupled to the elongated tubular member towards the distal end thereof and is rotatable relative thereto between a closed position and an open position. The surgical camera is rotated from the closed position to the open position upon passage of the surgical instrument through the lumen of the elongated tubular member and includes a proximal surface configured to facilitate translation of the surgical camera from the closed position to the open position upon contact of the surgical instrument with the proximal surface of the surgical camera within the lumen of the elongated tubular member.

Claims

1. A surgical camera assembly, comprising:

an elongated tubular member defining a longitudinal axis and having a lumen extending longitudinally therethrough, the elongated tubular member configured to permit passage of a surgical instrument therethrough;

a surgical camera rotatably coupled to the elongated tubular member towards a distal end thereof, the surgical camera rotatable between a closed position, wherein the surgical camera is substantially disposed within the lumen of the elongated tubular member, and an open position, wherein the surgical camera is substantially displaced from the lumen of the elongated tubular member, the surgical camera including a proximal surface configured to facilitate translation of the surgical camera from the closed position toward the open position upon contact of the surgical instrument with the proximal surface of the surgical camera within the lumen of the elongated tubular member.

2. The surgical camera assembly according to claim 1, wherein the surgical camera is biased toward the closed position.

3. The surgical camera assembly according to claim 1, wherein the proximal surface of the surgical camera defines a helical-shaped configuration.

4. The surgical camera assembly according to claim 1, further comprising at least one cleaning element, the at least one cleaning element configured to clean a lens of the surgical camera upon movement of the surgical camera from the closed position to the open position.

5. The surgical camera assembly according to claim 1, further comprising a seal member disposed within the lumen of the elongated tubular member, the seal member configured to inhibit the escape of fluid through the lumen of the elongated tubular member.

6. The surgical camera assembly according to claim 1, wherein the surgical camera is hingably coupled to the elongated tubular member via at least one hinge, the surgical camera rotatable about the at least one hinge between the open and closed positions.

7. A surgical camera assembly, comprising:

an elongated tubular member defining a longitudinal axis and having a lumen extending longitudinally therethrough, the elongated tubular member configured to permit passage of a surgical instrument therethrough;

a capsule coupled to the elongated tubular member at a distal end thereof, the capsule longitudinally translatable relative to the elongated tubular member between an initial position, wherein the capsule is disposed in abutting relation with the distal end of the elongated tubular member, and an extended position, wherein the capsule is spaced-apart from the elongated tubular member, the capsule configured to dock on the surgical instrument upon passage of the surgical instrument through the lumen of the elongated tubular member and at least partially through a lumen defined through the capsule such that the capsule is longitudinally translated in conjunction with longitudinal translation of the surgical instrument; and

a surgical camera rotatably coupled to the capsule, the surgical camera rotatable between a closed position, wherein the surgical camera is substantially disposed within the lumen of the capsule, and an open position, wherein the surgical camera is substantially displaced from the lumen of the capsule, the surgical camera translating in conjunction with the capsule between the initial position and the extended position.

8. The surgical camera assembly according to claim 7, wherein the surgical camera is biased toward the closed position.

9. The surgical camera assembly according to claim 7, wherein the capsule is biased toward the retracted position.

10. The surgical camera assembly according to claim 7, wherein the surgical camera is rotated from the closed position to the open position upon passage of the surgical instrument from the lumen of the elongated tubular member into the lumen of the capsule.

11. The surgical camera assembly according to claim 7, wherein the capsule includes a pick-up element disposed at a distal end thereof and extending inwardly into the lumen of the capsule to dock the capsule on the surgical instrument upon passage of the surgical instrument at least partially through the lumen of the capsule.

12. The surgical camera assembly according to claim 7, wherein the capsule further includes at least one cleaning element, the at least one cleaning element configured to clean a lens of the surgical camera upon movement of the surgical camera from the closed position to the open position.

13. The surgical camera assembly according to claim 7, further comprising a seal member disposed within the lumen of the elongated tubular member, the seal member configured to inhibit the escape of fluid through the lumen of the elongated tubular member.

14. The surgical camera assembly according to claim 7, wherein the surgical camera is hingably coupled to the capsule via at least one hinge, the surgical camera rotatable about the at least one hinge between the open and closed positions.

15. The surgical camera assembly according to claim 7, wherein the capsule is releasably coupled to the elongated tubular member.

16. A method of providing visualization within an internal surgical site, comprising the steps of:

providing a surgical camera assembly including an elongated tubular member having a lumen extending longitudinally therethrough and a surgical camera rotatably coupled to the elongated tubular member towards a distal end thereof;

inserting the surgical camera assembly through an opening in tissue such that the distal end of the elongated tubular member is disposed within the internal surgical site;

inserting a surgical instrument through the lumen of the elongated tubular member; and

translating the surgical instrument distally through the lumen of the elongated tubular member such that the surgical instrument contacts a proximal surface of the surgical camera, urging the surgical camera to rotate from a closed position, wherein the surgical camera is substantially disposed within the lumen of the elongated tubular member, to an open position, wherein the surgical camera is substantially displaced from the lumen of the elongated tubular member to permit passage of the surgical instrument therethrough.

17. The method according to claim 16, wherein the proximal surface of the surgical camera defines a helical-shaped configuration to facilitate rotation of the surgical camera from the closed position to the open position.

18. The method according to claim 16, further comprising the step of remocing the surgical instrument from the lumen of the elongated tubular member such that the surgical camera is returned to the closed position.

19. The method according to claim 16, further comprising a capsule coupled to the elongated tubular member at a distal end thereof, the capsule including a lumen extending therethrough.

20. The method according to claim 19, further comprising the steps of:

translating the surgical instrument distally to extend into the lumen of the capsule such that the capsule is docked on the surgical instrument; and

translating the surgical instrument further distally such that the capsule is similarly translated distally relative to the elongated tubular member from a retracted position to an extended position.
