Abstract

An instrument for bending a surgical rod includes first and second arm assemblies. The first arm assembly includes first and second arms having respective first and second receiving portions configured to receive the surgical rod therein. The second arm assembly includes third and fourth arms having respective third and fourth receiving portions configured to receive the surgical rod therein. The instrument is reconfigurable from an initial configuration in which the first and third receiving portions of the respective first and third arms engage the surgical rod such that spreading of the first and third receiving portions in a first direction bends the surgical rod in a first orientation and spreading of the first and third receiving portions in a second direction bends the surgical rod in a second orientation opposite to the first orientation.

Dependent claims

A method of use, comprising:

providing an instrument for bending a surgical rod including:
a first arm assembly including a first handle and a first arm extending from the first handle, the first arm having a first receiving portion, a first bend and a first plurality of teeth along the first bend;
and
a second arm assembly including a second handle and a second arm extending from the second handle, the second arm having a second receiving portion, a second bend and a second plurality of teeth along the second bend, the first bend and second bend being detachably associated with each other;
engaging the first receiving portion of the first arm and the second receiving portion of the second arm with the surgical rod;
and
bending the surgical rod through the engagement of the first plurality of teeth with the second plurality of teeth such that approximating the first and second handles in a first direction bends the surgical rod in a first orientation and approximating the first and second handles in a second direction different from the first direction bends the surgical rod in a second orientation different to the first orientation.
