Problems solved by technology

The cross bar of the existing varus foot orthopedic bracket is fixedly connected to the shoe holder, which is inconvenient and unscientific to adjust the angle, which leads to poor orthopedic effect and high recurrence rate
People have made many improvements to the above-mentioned varus foot orthosis, but a slight adjustment of the structure or position of a certain component of the orthosis may have a huge impact on the clinical effect and recurrence rate of the orthosis. Therefore, the above-mentioned improvements are still in progress

Embodiment 1

[0055] Such as figure 1 Shown is a multifunctional orthosis using the varus foot multifunctional orthopedic movable rod of the present invention.

[0056] to combine image 3 As shown in FIG. 6 , the two ends of the movable rod 1 are provided with axial holes 5 through which the axial shaft 4 passes; the movable rod 1 and the swing arm assembly 2 are connected through the axial shaft 4 .

[0057] Such as figure 2 As shown, the movable rod 1 includes two left threaded pipes 6 and right threaded pipes 7 that can be screwed together at one end, the left threaded pipe 6 is an internally threaded pipe, and the right threaded pipe 7 is an externally threaded pipe. When the threaded tube is screwed in and out, the axial expansion and contraction of the movable rod 1 is realized. to combine image 3 , 4 As shown, the other end of the left threaded pipe 6 is fixed together with the left end 8 of the movable rod 1. As shown in Figs. The radial shaft 3 with the parts 10 fixed toge...

Embodiment 2

[0060] Embodiment 2 is basically the same as Embodiment 1, except that the left helical pipe 6 has external threads, the right helical pipe 7 has internal threads, and the left helical pipe 6 can rotate inside the right helical pipe 7 .

Embodiment 3

[0062] It is basically the same as Embodiment 1, the difference is the varus foot multifunctional orthopedic movable rod, the movable rod 31 includes two horizontal bars 36 with gaps, the gap ends of the two horizontal bars 36 are parallel to each other, and in the gap A through hole 37 is formed at the place; the fixing assembly 38 can pass through the through hole 37 to fasten the two horizontal bars 36 together, and the fixing assembly 38 includes a top plate 39 and a bottom plate 310 with a protrusion adapted to the through hole 37, The fastening screws 311 can pass through the top plate 39 and the bottom plate 310 to be tightened.

Abstract

The invention relates to a varus foot multifunctional orthopedic movable rod, the movable rod can be stretched and contracted along its axial direction, the end of the movable rod is connected with an axial shaft for the rotary arm assembly to rotate along the axial direction of the movable rod, and the movable rod There is at least one radial shaft that can be used for the radial rotation of the swing arm assembly along the radial direction of the movable rod. The varus foot multifunctional orthopedic movable rod of the present invention has the structural characteristics of being able to expand and contract in the axial direction, and is connected with a radial shaft and an axial shaft, ensuring that children using the product of the present invention have no pain, and the orthopedic effect is better than that of the existing orthopedic brackets. The improvement rate is more than 25%. The clinical trials of 77 children showed that the excellent and good rate is close to 99%. The degree of correction of foot varus deformity is 5-15°, and the recurrence rate is less than 10%. In particular, the movable rod with limiting components and concave-convex grooves has been used by 73 children. The rotation angle of less than 180° has a more significant improvement in the orthopedic effect, and it is easier to process and more convenient to install.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a multifunctional orthopedic active rod for varus feet. Background technique [0002] Inversion foot is a common foot deformity in children, with an incidence rate of about 1‰~4.5‰. Males are more than females, and unilateral is more than bilateral. The affected foot has different degrees of deformities such as adduction, varus, and sagging. If left untreated or improperly treated, it will leave lifelong disabilities. The disease can be divided into congenital and acquired according to the cause of the disease. The deformity of congenital varus feet can be found after birth, so the diagnosis is not difficult. Acquired clubfoot can generally be caused by diseases such as cerebral palsy, spina bifida, and trauma. [0003] As stated in Chinese patent CN200920018249, the best conservative treatment method for congenital varus foot is the Ponseti method, the main point of w...
