Description

Technical Field

[0001] The present application relates to the technical field of intramedullary nails, and more specifically, to a triangular support frame for intramedullary nails. Background Art

[0002] The intramedullary nail is an orthopedic internal fixation device among medical devices. Its structure comprises an intramedullary nail rod, a proximal locking screw hole is arranged at the proximal end of the intramedullary nail rod, a decompression plane is arranged on the surface of the intramedullary nail rod, and more than one long strip-shaped decompression plane is arranged on the surface of the intramedullary nail rod. The decompression plane can extend from the proximal end of the intramedullary nail rod to the distal end of the intramedullary nail rod. A locking screw positioning screw hole and a connecting sleeve positioning groove are arranged at the proximal end of the intramedullary nail rod.

[0003] According to the search, the Chinese patent with the announcement number CN217040260U discloses an intramedullary nail, which includes a distal end of a nail body composed of a first curved section and a second curved section, wherein the first curvature radius of the first curved section is smaller than the second curvature radius of the second curved section, and a proximal end of the nail body connected to the distal end of the nail body and composed of a third curved section, wherein the third curvature radius of the third curved section matches the first curvature radius. Since the first curvature radius of the first curved section in the distal end of the nail body is smaller than the second curvature radius of the second curved section, that is, the curvature of the outer wall of the distal end of the nail body is smaller, when the intramedullary nail is placed in the medullary cavity, the contact area between the intramedullary nail and the inner wall of the medullary cavity can be effectively reduced, thereby effectively alleviating the current technical problem of poor bone repair effect due to the large contact area between the intramedullary nail and the inner wall of the medullary cavity.

[0004] Regarding the above-mentioned related technologies, the applicant believes that its fixed structure is not convenient for adjusting the curvature and other data of different curved sections. At the same time, its structure is not stable enough after installation and its practicality is not high. Therefore, we propose a triangular support frame for intramedullary nails.
