Abstract
The invention discloses an intramedullary nail for femoral fracture. The intramedullary nail comprises a main nail, a head nail and an anti-rotation nail, wherein the main nail consists of a near endpart, a transition part and a far end part, and the head nail penetrates through a head nail hole located in the near end part; the anti-rotation nail penetrates through an anti-rotation nail hole located in the head nail, and one end of the anti-rotation nail bulges out of the outer side surface of the head nail. The intramedullary nail is used for treating femoral near-end fracture and is reasonable in structure, the hole for inserting the anti-rotation nail is formed in the head nail, after the anti-rotation nail is screwed into the head nail, the insertion end of the head nail is of a double-head structure, double-plane fixation is realized in a femur head, rotation of the femur head is effectively prevented, and the anti-rotation capacity of the head nail is improved; besides, the hole for accommodating the anti-rotation nail is located in the head nail, formation of a hole for separately accommodating the anti-rotation nail in bone is avoided, operation steps are reduced, pain ofa patient is relieved, and recovery of the patient is facilitated. Meanwhile, entering and penetrating-out parts, penetrating through the head nail, of the anti-rotation nail are right located on twosides of the main nail, so that limited sliding of the head nail is increased, and excessive retreat of the head nail or cutting in hip joints is avoided.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to an intramedullary nail for femur fracture. Background technique [0002] Intramedullary nail is a commonly used instrument for orthopedic internal fixation in medical devices, which is related to the reliability of bone fixation. Therefore, intramedullary nail is closely related to the effect of orthopedic treatment. [0003] Patent CN206852653U discloses an improved intramedullary nail internal fixation device for proximal femoral fractures, which relates to the technical field of medical devices. The device includes an intramedullary nail, a fracture fixation nail, and an intramedullary nail fixation nail. The intramedullary nail is placed in the bone marrow of the proximal femur. Intramedullary nailing. The present invention is simple in operation and strong in practicability, fully utilizes the biological and mechanical properties of the living bone, follows the...
