wherein the extended portion of the third part is received into the hollow interior portion of the fourth part and configured to rotate about the second pivot axis.
3. The device of claim 2 , wherein the extended portion of the first part comprises a cylindrical portion.
4. The device of claim 3 , wherein the extended portion of the third part comprises a cylindrical portion.
5. The device according to claim 2 , wherein at least one of the first part, second part, third part, and fourth part includes an interior-facing surface with a plurality of protrusions configured to interact with the spinous processes.
6. The device according to claim 2 , wherein each of the first part, second part, third part, and fourth part includes an instrument coupling hole.
7. A spinous process device, comprising:
a first plate extending along a first pivot axis comprising:
a first part configured to abut a side of a first spinous process and having a first extended portion;
a second part configured to abut a side of a second spinous process and having a first hollow interior portion,
wherein the first extended portion is received into the first hollow interior portion of the second part and configured to rotate about the first pivot axis;
a second plate extending along a second pivot axis comprising:
a third part configured to abut an opposite side of the first spinous process as the first part and having a second extended portion; and
a fourth part configured to abut an opposite side of the second spinous process as the second part and having a second hollow interior portion,
wherein the second extended portion of the third part is received into the second hollow interior portion of the fourth part and configured to rotate about the second pivot axis,
a coupling mechanism configured to couple the first plate and the second plate, the coupling mechanism comprising:
a first member comprising a first arm;
a second member comprising a second arm including a threaded hole;
a hollow cylinder having a first opening, a second opening, and a third opening,
wherein the first plate is coupled to the second plate with the first arm received in the second opening of the hollow cylinder, the second arm received in the third opening of the hollow cylinder, and
wherein a securing screw extends into the first opening of the hollow cylinder and engages the threaded hole in the second arm.
8. The device of claim 7 , wherein the first extended portion and the second extended portion comprise cylindrical portions.
9. The device according to claim 7 , wherein at least one of the first part, second part, third part, and fourth part includes an interior-facing surface with a plurality of protrusions configured to interact with the spinous processes.
10. A spinous process device, comprising:
a first plate extending along a first pivot axis and comprising:
a first part configured to abut a side of a first spinous process and having a first cylindrical portion;
a second part configured to abut a side of a second spinous process and having a first hollow interior portion configured to slidably and rotatably receive the first cylindrical portion,
a second plate extending along a second pivot axis and comprising:
a third part configured to abut an opposite side of the first spinous process as the first part and having a second cylindrical portion; and
a fourth part configured to abut an opposite side of the second spinous process as the second part and having a second hollow interior portion configured to slidably and rotatably receive the second cylindrical portion; and
a coupling mechanism comprising:
a first member with a first arm extending from one of the first part and the second part of the first plate;
a second member with a second arm including a threaded hole extending from one of the third part and the fourth part of the second plate; and
a coupler body comprising a hollow cylinder having a first opening, a second opening, and a third opening, the coupler body allowing the first plate to translate and rotate relative to the second plate to adjust a distance and an angle between the first plate and the second plate;
wherein the first plate is coupled to the second plate with the first arm received in the second opening of the hollow cylinder, the second arm received in the third opening of the hollow cylinder, and
wherein a securing screw extends into the first opening of the hollow cylinder and engages the threaded hole in the second arm.
