Abstract

A surgical device includes a jaw portion and a shaft portion that is pivotably coupled to the jaw portion. The shaft portion defines an interior space having first and second openings on respective radially-opposite sides of the shaft portion. A camera assembly is coupled to the shaft portion and is moveable between a first position, in which the camera assembly is positioned within the interior space of the shaft portion, and, for example, second and third positions, in which the camera assembly extends through a respective one of the first and second radially-opposite openings of the shaft portion. In this manner, the camera assembly may be positionable on, and may provide imaging data of, either side of the surgical device, irrespective of which lateral side the jaw portion is articulated relative to the shaft portion.

Claims

1. A surgical device, comprising:

a jaw portion comprising a pair of opposing jaw members;

a shaft portion pivotably coupled to the jaw portion, wherein the shaft portion defines an interior space having at least one opening on a side of the shaft portion;

a camera assembly coupled to the shaft portion proximally of the jaw portion and moveable between a first position, in which the camera assembly is positioned within the interior space of the shaft portion, and a second position, in which the camera assembly extends through the at least one opening of the shaft; and

a single drive mechanism coupled to the jaw portion and the camera assembly, the single drive mechanism is adapted to cause the camera assembly to automatically move to the second position and to articulate the jaw portion relative to the shaft portion such that the camera assembly provides imaging of the jaw portion.

2. The surgical device of claim 1, wherein the at least one opening includes first and second openings on respective radially-opposite sides of the shaft portion.

3. The surgical device of claim 2, wherein the camera assembly is moveable so as to extend through a respective one of the first and second radially-opposite openings of the shaft portion.

4. The surgical device of claim 1, wherein the camera assembly includes at least one camera and at least one light source.

5. The surgical device of claim 3, wherein the jaw portion defines a first longitudinal axis, the shaft portion defines a second longitudinal axis, and the jaw portion is pivotable relative to the shaft portion about a first pivot axis that is perpendicular to the first and second longitudinal axes.

6. The surgical device of claim 5, wherein the camera assembly is pivotably coupled to the shaft portion about a second pivot axis that is parallel to the first pivot axis.

7. The surgical device of claim 5, wherein the jaw portion is articulatable to either one of laterally-opposite sides of the shaft portion.

8. The surgical device of claim 7, wherein the camera assembly is moveable so as to extend through a respective one of the first and second openings of the shaft portion that is located on the same lateral side as the lateral side to which the jaw portion is articulated.

9. The surgical device of claim 8, wherein the shaft portion includes a drive mechanism that operates to cause the camera assembly to automatically extend through the respective one of the first and second openings of the shaft portion that is located on the same lateral side as the lateral side to which the jaw portion is articulated.

10. The surgical device of claim 9, wherein the single drive mechanism is adapted to cause the camera assembly to automatically extend through the respective one of the first and second openings of the shaft portion and to articulate the jaw portion relative to the shaft portion.

11. The surgical device of claim 8, wherein the camera assembly is at least partially manually moveable by an operator so as to extend through a respective one of the first and second openings of the shaft portion.

12. The surgical device of claim 1, wherein the camera assembly includes a camera housing and a support arm.

13. The surgical device of claim 12, wherein the support arm is coupled at a first location to the shaft portion and at a second location to the camera housing.

14. The surgical device of claim 13, wherein the support arm is pivotable relative to the shaft portion about a pivot axis that is parallel to an axis about which the jaw portion is pivotable relative to the shaft portion.

15. The surgical device of claim 13, wherein the camera housing is pivotable relative to the support arm about a pivot axis that is parallel to an axis about which the jaw portion is pivotable relative to the shaft portion.

16. The surgical device of claim 1, wherein the camera assembly includes a camera and two light sources.

17. The surgical device of claim 16, wherein each of the two light sources is located on a respective side of the camera.
