<p>SKELETON TRACTION PIN This skeleton traction pin comprises three parts- a proximal part (A), a middle part (B) and the distal part (C) which is sharpened. The proximal and distal parts fit into the middle part by means of screw threads. The proximal part fits into the drill and enables the pin to be drilled into the bone, just like the conventional pin. Once the fully assembled pin is drilled into the bone, the sharpened end C can be unscrewed and removed thus preventing its re-use and injury to the patient and health care personnel. After the purpose of pin is fulfilled, its removal is facilitated by unscrewing the exposed part (B) and pulling out the part which is inside the bone (A) thus preventing any chance of infection and contamination from the outer environment.</p> |
