Project Overview

Spinal deformity surgery is common in pediatric orthopedics. Often cobalt chrome, stainless steel, or titanium rods in 4.0-6.0 mm diameters are used to correct the deformity and hold the correction. Often the relative length of the rod needed for the deformity correction can be difficult to get precisely correct prior to implanting the devices. Occasionally, if the rod is too long following insertion, it will need to be cut. Using current cutting devices can be very difficult, as they are very large and make wound insertion difficult. In addition to this, a large amount of force generated by the user is required, which can be straining for surgeons. This project aims to design a rod cutter that can be placed easily into the wound and reduce the physical burden placed on the user.
