Supreme Distracter
A Fixation Device For Internally Or Externally Fixing Fractures Comprising At Least One Nitinol Wire Having An S-Shaped Section And Two Ends Wherein Each Of Said Two Ends Forms A Hook For Hooking Into A Bone Section Of A Fractured Bone. This Device Can Be Made From Nitinol Which Has A Transformation Temperature Between 25 Deg C. And 35 Deg C. In Addition, This Device Can Have A Diameter Between 0.6 Mm And 5 Mm. The Device Can Be Inserted Using The Following Process Which Starts By Cooling The Wire Below A Transfer Temperature Such That The Nitinol Wire Forms In A Martensite State. Next, The Nitinol Wire Is Inserted Into A Interphalangeal Bone Underneath A Patients Skin. Next, The Nitinol Wire To Heats Up Inside A Patients Body Above The Transfer Temperature.; Finally, The Wire Transforms Wire From A Martensite State To An Austenite State Wherein When The Nitinol Wire Elongates In A Longitudinal Direction To Generate A Distraction Force.
