Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a simple, ingenious, and reasonable bone nail channel support reinforcement rod, which can effectively solve the problem of removing the metal plate and the metal nail after the patient's fracture has healed. Leaving screw holes in the surgical site, resulting in reduced bone strength and even cancellous bone collapse

Embodiment approach

[0016] figure 1 shows the first embodiment of the present invention, from figure 1 It can be seen from the figure that the diversion groove 2 is a through hole penetrating through the rod body 1 along the length direction.

[0017] figure 2 shows a second embodiment of the present invention, from figure 2 It can be seen from the figure that the diversion groove 2 is a groove arranged at the edge of the rod body 1 , opening outward and penetrating through the rod body 1 .

[0018] image 3 The third embodiment of the present invention is shown, in which a plurality of convex ridges 3 are evenly distributed on the circumference of the rod body 1 , and flow guide grooves 2 are formed between two adjacent convex ridges 3 .

[0019] The product of the present invention is clinically used in orthopedic surgery. During orthopedic surgery, the classic internal fixation device "metal bone plate and metal bone screw" is used to fix the fracture site. After the patient's fracture h...

Abstract

The invention belongs to the field of medical instruments and relates to a reinforcing device used when a metal nail plate is detached after internal fracture fixation operation union of a patient, in particular to a reinforcing bar for supporting a pore passage of a bone nail. The reinforcing bar for supporting the pore passage of the bone nail comprises a cylindrical bar body used for supporting the pore passage of the bone and a diversion groove is formed in the bar body and is a through hole penetrating through the bar body. The reinforcing bar for supporting the pore passage of the bone nail is used for effectively solving the problems that when the metal bone connecting plate and metal bone connecting nails are detached after internal fracture fixation operation union, the perforated portion of the fracture portion is unstable and the cancellous bones collapse.

Description

technical field [0001] The invention belongs to the field of medical instruments and equipment, and relates to a reinforcing device used when a metal nail plate is removed after a patient's fracture internal fixation operation heals, in particular to a bone nail channel supporting reinforcing rod. Background technique [0002] During fracture surgery, metal plates and metal screws are usually used for internal fixation of fractures. After the fracture has healed, the metal nails and metal plates need to be removed, and a large number of screw channels will be left at the metal nails. These channels reduce the The bone strength at the site, especially the nail channel passing through the fracture surface, increases the local instability, which is likely to cause secondary fractures in the patient; the cancellous bone near the joint can easily lead to cancellous bone after the metal screws are removed. Bone collapses, resulting in more serious joint problems, which increases t...
