Magnetic targeting device to eliminate the need for the x-ray machines that locate the screw holes in bone repair procedures
In a joint venture with Plastics One, Triad Semiconductor,
Virginia Tech and Carilion Biomedical Institute have created a
device that could change how doctors perform medical procedures
for broken bones.
The medical procedure to repair broken thigh
bones is long and tedious.
First doctors thread a metal pin
through the segments of the fractured bone, typically starting at
the hip bone sliding the pin down the leg.
The doctors then drill
screw holes - but there's a catch.
The screw holes must line
up with the pre-drilled screw holes in the metal pin already
inserted in the leg.
Both sets of screw holes must line up with
one another precisely; it's this part of the procedure that
takes the longest and the reason the new device was created.
Doctors use large x-ray machines and a hand held drill for this
stage of the surgery.
It is very tedious and exposes the patient
and the doctor to large doses of radiation from the x-ray
machines during the course of the procedure.
The doctor takes
x-rays of the leg and the pin to determine the exact location of
the pin holes.
This, as you can imagine, can take a lot of time
to line up a hand held drill with the pre-drilled screw holes
using only a live x-ray as a guide.
The magnetic targeting device
is a hand held device that locates the screw holes and will
eliminate the need for the x-ray machines.
Teaming up with
companies such as Triad Semiconductor, Virginia Tech and Plastics
One, this breakthrough in technology was created.
