Embodiment Construction

[0017] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] combine figure 1 As shown, the clavicular intramedullary nail includes a round rod-shaped main body 1, which has opposite distal ends 11 and proximal ends 12. The main body 1 is provided with a locking hole 13 near the distal end, and the locking hole 13 is connected to the main body. 1. The axial direction forms an included angle less than 90°. The main body 1 is formed with a hollow cavity along its axial direction. The main body 1 is provided with a s...

Abstract

The invention discloses an intramedullary interlocking internal nail which comprises a cylindrical main body. The main body is provided with a far end and a rear end opposite to the far end. A locking hole is formed in the far end close to the body. An included angle smaller than 90 degrees is formed between the locking hole and the axial direction of the main body. The main body is provided with a hollow cavity in the axial direction of the main body. A self-locking structure is arranged at the position of the near end of the main body. The self-locking structure is communicated with the hollow cavity. A core rod is inserted into the hollow cavity. The core rod axially moves so as to move the self-locking structure to expand outwards. The intramedullary interlocking internal nail is simple in structure, high in safety, suitable for clinic requirement and high in intramedullary nail tensile strength, and when the intramedullary interlocking nail is in use, the near end can be locked, and the purposes that a surgical incision is small and operation is rapid and convenient can be achieved.

Description

technical field [0001] The present application relates to an orthopedic medical device, in particular to a clavicular intramedullary nail. Background technique [0002] In the usual interrupted clavicle fracture, the injured part is restored by surgical techniques. [0003] Intramedullary clavicle nailing is osteosynthesis, and it is also a new technology of modern fracture fixation. It uses indirect fracture reduction technology and fixes with intramedullary implants to maintain fracture alignment, which minimizes surgical exposure and soft tissue stripping, and can Improve fracture healing rate. [0004] The traditional clavicular intramedullary nail cannot achieve self-locking at the proximal end when in use, and the surgical incision is large, making the operation not convenient enough. [0005] In view of this, it is necessary to provide a novel clavicle intramedullary nail. Contents of the invention [0006] The object of the present invention is to provide a clav...
