Abstract

A rod bender for bending a surgical rod includes first and second arms. The first arm includes first and second engaging portions. The second arm includes third and fourth engaging portions. The rod bender is reconfigurable between a first configuration in which the second and fourth engaging portions of the respective first and second arms engage the surgical rod such that spreading of the first and third engaging portions of the respective first and second arms bends the surgical rod in a first orientation and a second configuration in which the first engaging portion of the first arm and the fourth engaging portion of the second arm engage the surgical rod such that spreading of the second engaging portion of the first arm and the third engaging portion of the second arm bends the surgical rod in a second orientation opposite to the first orientation.

First claim

What is claimed is:

1. A rod bender comprising:
a first arm including first and second rod engaging portions, each configured to securely engage a surgical rod; and
a second arm including third and fourth rod engaging portions, each configured to securely engage the surgical rod, a cavity configured to receive a portion of the first arm, the cavity defined between the third and fourth rod engaging portions and between a body of the second arm and a guide portion adjacent at least one of the third and fourth rod engaging portions of the second arm, a first pivot portion, and a second pivot portion, each pivot portion extending from the second arm.

2. The rod bender of claim 1 , wherein the first arm defines a first longitudinal axis, and at least one of the first and second rod engaging portions are at an angle to the first longitudinal axis.

3. The rod bender of claim 1 , wherein the second arm defines a second longitudinal axis, and at least one of the third and fourth rod engaging portions are at an angle to the second longitudinal axis.

4. The rod bender of claim 1 , wherein a dimension is defined between the body and the guide portion sized to receive the portion of the first arm.

5. The rod bender of claim 1 , wherein the guide portion is parallel to the body.

6. The rod bender of claim 1 , wherein, in a first configuration, the first rod engaging portion of the first arm and the third rod engaging portion of the second arm are engaged with the surgical rod, and spreading the second rod engaging portion of the first arm and fourth rod engaging portion of the second arm bends the surgical rod in a first orientation.

7. The rod bender of claim 6 , wherein, in a second configuration, the second rod engaging portion of the first arm and the third rod engaging portion of the second arm are engaged with the surgical rod, and the portion of the first arm is received in the cavity of the second arm.

8. The rod bender of claim 7 , wherein, from the second configuration to a third configuration, the first rod engaging portion of the first arm and fourth rod engaging portion of the second arm are spread such that the surgical rod is in a second orientation.

9. The rod bender of claim 7 , wherein the second arm defines a second longitudinal axis, and the third rod engaging portion is at an angle to the second longitudinal axis.

10. A rod bender comprising:
a first arm including first and second rod engaging portions, each configured to securely engage a surgical rod;
a second arm including third and fourth rod engaging portions, each configured to securely engage the surgical rod, a body lateral of and parallel to an axis extending through the third and fourth rod engaging portions, a first pivot portion, and a second pivot portion, each pivot portion extending from the second arm; and
a guide portion parallel to the axis, and a dimension defined between the body and the guide portion sized to receive a portion of the first arm.

11. The rod bender of claim 10 , wherein the first arm defines a first longitudinal axis, wherein at least one of the first and second rod engaging portions of the first arm are at a first angle to the first longitudinal axis, and at least one of the third and fourth rod engaging portions are at a second angle to the axis of the second arm.

12. The rod bender of claim 10 , wherein, in a first configuration, the first rod engaging portion of the first arm and the third rod engaging portion of the second arm are engaged with the surgical rod, and spreading the second rod engaging portion of the first arm and fourth rod engaging portion of the second arm bends the surgical rod in a first orientation.

13. The rod bender of claim 12 , wherein, in a second configuration, the second rod engaging portion of the first arm and the third rod engaging portion of the second arm are engaged with the surgical rod, and a portion of the first arm intersects the axis of the second arm.

14. The rod bender of claim 13 , wherein, from the second configuration to a third configuration, the first rod engaging portion of the first arm and fourth rod engaging portion of the second arm are spread such that the surgical rod is in a second orientation.

15. A rod bender comprising:
a first arm including first and second rod engaging portions, each configured to securely engage a surgical rod; and
a second arm including third and fourth rod engaging portions, each configured to securely engage the surgical rod, and a first pivot portion and a second pivot portion configured to receive a portion of the first arm, each pivot portion extending from the second arm, wherein in a first configuration, the first rod engaging portion of the first arm and the third rod engaging portion of the second arm are engaged with the surgical rod, and spreading the second rod engaging portion of the first arm and fourth rod engaging portion of the second arm bends the surgical rod in a first orientation, and wherein in a second configuration the second rod engaging portion of the first arm and the third rod engaging portion of the second arm are engaged with the surgical rod, and the portion of the first arm engages at least one of the first pivot portion and the second pivot portion.

16. The rod bender of claim 15 , wherein, from the second configuration to a third configuration, the first rod engaging portion of the first arm and fourth rod engaging portion of the second arm are spread such that the surgical rod is in a second orientation.
