## Abstract

A compound rod bender includes a first handle arm and a second handle arm coupled to a first pivot point. A body portion of the rod bender is coupled to the first handle arm at a second pivot point and the second handle arm is coupled to the body portion at a third pivot point. The body portion also includes first and second distal arms configured with first and second rolling elements coupled to distal ends of the first and second distal arms. A barrel is provided on the body portion which is positioned on a center area of the body portion.

## Claims

### Claim 1

A compound rod bender comprising:
a first handle arm and a second handle arm coupled to a first pivot point;
a body portion coupled to the first handle arm at a second pivot point and the second handle arm coupled to the body portion at a third pivot point,
wherein the body portion comprises first and second distal arms configured with a first and second rolling elements coupled to distal ends of the first and second distal arms, and the body portion configured with a barrel positioned on a center portion of the body portion,
wherein the barrel is rotatable and may be translated on the body portion into different positions for accommodating varying rod diameters.

### Claim 2 (depends on 1)

The compound rod bender of claim 1, wherein the first and second rolling elements are rotatable.

### Claim 3 (depends on 1)

The compound rod bender of claim 1, wherein the barrel is configured with a plurality of bending surfaces.

### Claim 4 (depends on 1)

The compound rod bender of claim 1, wherein first and second handle arms are configured to pivot with respect to each other.

### Claim 5 (depends on 1)

The compound rod bender of claim 1, wherein the first and second rolling elements are configured for conforming to the radius of the rod.

### Claim 6

A spinal rod bending system comprising:
an elongated spinal rod;
a compound rod bender for manipulating an elongated spinal rod comprising:
a first handle arm and a second handle arm coupled to each other at a first pivot point;
a body portion coupled to the first handle arm and the second handle arm at second and third pivot points,
wherein the body portion comprises first and second distal arms configured with first and second rolling elements coupled to distal ends of the first and second distal arms, and the body portion configured with a barrel positioned on a center portion,
wherein the barrel is rotatable and may be translated on the body portion into different positions for accommodating varying rod diameters.

### Claim 7 (depends on 6)

The system of claim 6, wherein the first and second rolling elements are rotatable.

### Claim 8 (depends on 6)

The system of claim 6, wherein the barrel is configured with a plurality of bending surfaces.

### Claim 9 (depends on 6)

The system of claim 6, wherein first and second handle arms are welded to each other at the first pivot point.

### Claim 10 (depends on 6)

The system of claim 6, wherein the first and second rolling elements are configured for conforming to the radius of the rod.

### Claim 11

A method for manipulating a spinal rod comprising:
providing a compound rod bender, the compound rod bender comprising:
a first handle arm and a second handle arm coupled to each other at a first pivot point;
a body portion coupled to the first handle arm and the second handle arm at a second and third pivot point,
wherein the body portion comprises first and second distal arms configured with first and second rolling elements coupled to distal ends of the first and second distal arms, and the body portion configured with a barrel positioned on a center portion of the body portion,
positioning the spinal rod between the rolling elements and the barrel of the compound rod bender;
actuating the first and second handle arms thereby bending the spinal rod; and
rotating and translating the barrel into different positions for accommodating varying rod diameters.

### Claim 12 (depends on 11)

The method of claim 11, wherein the first and second rolling elements are rotatable.

### Claim 13 (depends on 11)

The method of claim 11, further comprising the step of pivoting the first and second handle arms with respect to each other at the first pivot point.
