ABSTRACT:
A protective device and method for the removal and disposal of spinal needles. The protective device is comprised of a needle pulling assembly upon which is slidably mounted an external housing. In operation, a needle to be removed from a patient is engaged in the needle cradle portion of the needle pulling assembly. The external housing is moved into contact with the patient's skin and the needle is withdrawn by pulling on the pulling rod portion of the needle pulling assembly in a direction away from the patient. The needle is withdrawn into the interior of the external housing, thereby covering the entire length of the needle. The pulling assembly is then locked into place and the entire assembly including the withdrawn needle can be disposed of, thereby avoiding the possibility of needle pricks by contaminated spinal needles.
