Abstract

A surgical device is disclosed along with methods of using the same. The surgical device may include an outer sheath and a collar assembly. The collar assembly may be coupled to the outer sheath and may include a first arm coupled to the outer sheath at a first hinge; a second arm coupled to the first arm at a second hinge; and a collar coupled to the second arm. The collar assembly may be movable from an un-deployed position where the first arm and the second arm extend the collar distally from the outer sheath to a deployed position where the collar is aligned with the first channel of the outer sheath. Also, the first arm, the second arm, and the collar may be positioned substantially within a cross-sectional area of a distal end of the outer sheath when the collar assembly is in the un-deployed position.

Claims

1. A surgical device comprising:

an outer sheath defining a first channel therein;

a suturing applicator;

a collar assembly coupled to the outer sheath, wherein the collar assembly comprises;

a first arm coupled to the outer sheath at a first hinge positioned substantially at a first end of the first arm;

a second arm coupled to the first arm at a second hinge positioned substantially at a second end of the first arm; and

a collar coupled to an end of the second arm opposite the second hinge; and

wherein the collar assembly is movable from an un-deployed position where the first arm and the second arm extend the collar distally from the outer sheath to a deployed position where the collar is aligned with the first channel of the outer sheath, wherein the suturing applicator is distally extendable from the first channel toward the collar, when the collar assembly is in the deployed position, and wherein a distal cross section of the collar assembly is smaller when the collar assembly is in the un-deployed position than when the collar assembly is in the deployed position.

2. The surgical device of claim 1, wherein the first arm, the second arm, and the collar are positioned substantially within a cross-sectional area of a distal end of the outer sheath when the collar assembly is in the un-deployed position.

3. The surgical device of claim 1, wherein the collar assembly further comprises a spring rod extending from the first arm to at least one of the second arm and the collar, wherein the spring rod biases the collar assembly to the deployed position.

4. The surgical device of claim 1, wherein the collar assembly further comprises a spring rod extending from the first arm to at least one of the second arm and the collar, wherein the spring rod biases the collar assembly to the un-deployed position.

5. The surgical device of claim 4, wherein the collar assembly further comprises a wire extending proximally from at least one of the second arm and the collar through the outer sheath, wherein the wire is configured to transmit a proximally directed force to at least one of the second arm and the collar to move the collar assembly to the deployed position.

6. The surgical device of claim 1, wherein the suturing applicator is a needle.

7. The surgical device of claim 6, wherein the collar comprises a cap preventing the suturing needle from extending through the cap when the collar assembly is in the deployed position.

8. The surgical device of claim 1, wherein the collar comprises a hollow center aligned with the first channel of the outer sheath and positioned to receive at least a portion of the suturing applicator.

9. The surgical device of claim 8, wherein the collar comprises a cap on a distally oriented side of the hollow center.

10. The surgical device of claim 1, further comprising a first electrode and a second electrode.

11. The surgical device of claim 10, wherein the first electrode and the second electrode are positioned opposite one another when the collar assembly is in the deployed position.

12. The surgical device of claim 10, wherein the first electrode is positioned on the collar and wherein the second electrode is positioned on the first arm.

13. The surgical device of claim 10, wherein the collar assembly is the first electrode and the first arm is the second electrode.
