Elastic intramedullary nail with functions of pressurizing and resisting rotation

The invention relates to an elastic intramedullary nail with functions of pressurizing and resisting rotation and belongs to the technical field of medical instruments for the orthopedics department. According to the technical scheme, the elastic intramedullary nail used for the internal fixing of long bone metaphysis comminuted fracture is characterized in that the head of the intramedullary nail and the tail of the intramedullary nail respectively bend towards the same side of the middle of the intramedullary nail, the bending parts of the head of the intramedullary nail and the tail of the intramedullary nail and the middle of the intramedullary nail are located on the same plane, and grooves are respectively formed in intramedullary nail bodies on two sides of the bent arc shapes of the head of the intramedullary nail, the middle of the intramedullary nail and the tail of the intramedullary nail. The elastic intramedullary nail has the advantages that a traditional straight intramedullary nail is initiatively changed into the bent arc-shaped intramedullary nail, the intramedullary nail has the functions of elastic pressurizing and preventing transverse rotation when the intramedullary nail is used to perform internal fixing through a locking screw, new functions of the intramedullary nail in the internal fixing are provided, the internal fixing effect of the intramedullary nail is increased, fracture healing is accelerated, the pain of patients is reduced, a new powerful tool is provided for the treatment of the long bone fracture of the orthopedics department, and the intramedullary nail is worthy of popularization and use.
