Description

Cortical bone screw for taking out broken nail Technical Field The utility model relates to the technical field of cortical screws for taking out broken nails, in particular to a cortical screw for taking out broken nails. Background The bone nail is an inactive surgical metal implant for bone jointing, consists of cortical bone nails (full threads and half threads) and cancellous bone nails (full threads and half threads), is suitable for people, is applied to stable fracture, revision surgery, joint fusion and reconstruction of small bones of feet, ankles and toes, can be used for adult and pediatric patients, is structurally characterized by comprising a front end blade part, a middle section cylinder and a tail part, wherein the blade part is provided with a flat blade, a conical blade and a thread blade, the tail end is provided with a round, square, triangular and flat shape, and the bone fracture of the patient is usually positioned by using the screw in bone surgery treatment, and the screw fracture condition occurs in a plurality of patients with the screw implanted inside the bone in real life. Most of bone screws used in the existing orthopedic surgery treatment are inconvenient to take out after being broken, doctors mostly take out by adopting pliers, but when part of the screws are broken in bones, the pliers are inconvenient to enter the bones, so that broken nails are inconvenient to take out in the bones. To overcome these disadvantages, the present utility model provides a cortical bone screw for the removal of a broken nail. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a cortical bone screw for taking out a broken nail.
