Regulation-control orthosis for coronal plane deformity of ankle

A coronal plane and orthotic technology, applied in the direction of fixators and external fixators, can solve the problems of complex and bulky orthotic structures, lack of rapid expansion and contraction functions, and unfavorable functional training, so as to avoid soft tissue damage, low complications, and structural stability. Simple and neat effect

Embodiment 1

[0050] Embodiment one sees Figure 1-3 As shown, this ankle joint coronal deformity regulating orthosis is composed of a bone fixation bracket, a steel pin fixing clip connected to the bone fixing bracket, and a steel pin clamped in the steel pin fixing clip.

[0051] The bone fixation bracket includes a distal hole ring 1, a proximal hole full ring 2 arranged at the middle or upper part of the tibia, and two fast-stretching extension rods 3 connected between the distal hole ring and the proximal hole full ring. , a threaded hole ring connecting rod 4 connected between the far-end hole ring and the near-end hole full ring, and the threaded hole ring connecting rod 4 is adjustable through the up and down adjustment nut 6 and set The arc-shaped hole ring 5 (also called 1 / 4 hole ring) at the middle and lower part of the tibia.

[0052] The reason why the bone fixation bracket is designed in this way is that ankle varus, valgus deformity, and contracture joint deformity are all c...

Embodiment 2

[0079] Embodiment two see Figure 12-14 , the difference from Embodiment 1 is that the distal hole ring 1 in Embodiment 2 is a C-shaped ring of the distal hole arranged at the middle part of the calcaneus, and the ankle joint coronal deformity regulating orthosis at this time is Deformity stretching orthosis is suitable for stretching orthosis of ankle joint varus and valgus deformity.

[0080] The introduction of the stretching orthopedic operation for ankle varus and varus deformity using the second embodiment is as follows.

[0081] 1. Stretch orthopedics is aimed at contracture joint deformities. Without any surgical intervention on the local deformity, according to the theory of stress regeneration control, the stretch orthopedic function of external fixation is applied. Orthopedic principle, slow stretching, the orthopedic technique that gradually corrects deformities.

[0082] 2. Suitable for various contracture joint deformities.

[0083] There are two kinds of dist...

Abstract

A regulation-control orthosis for coronal plane deformity of an ankle is formed by a bone fixing support, steel needle fixing clamps connected onto the bone fixing support and steel needles clamped in the steel needle fixing clamps; the bone fixing support comprises a far end hole ring, a near end hole full ring arranged at the middle or middle upper section of a tibia, at least two fast extending lengthening rods connected between the far end hole ring and the near end hole full ring, a hole ring connecting rod provided with threads and connected between the far end hole ring and the near end hole full ring, and an arc hole ring adjustably connected to the hole ring connecting rod by an up-and-down adjusting nut and arranged at the middle lower section of the tibia. The regulation-control orthosis coronal plane deformity of the ankle is special for treating the strephexopodia or strephenopodia deformity of the ankle caused by synostosis, can perform traction, resetting, fixing and deformity correcting on fracture or deformity of the ankle in introversion and extroversion spaces, and is suitable for the traction, fixing and correcting on the coronal place of the ankle.

Description

technical field [0001] The invention relates to a bone external fixator, in particular to an orthopedic external fixator for treating varus deformity or valgus deformity of the ankle. Background technique [0002] The existing orthosis for the treatment of ankle deformities is generally the Ilizarov ring external fixator. The external fixator has a complex and bulky structure, does not have the function of rapid stretching and valgus correction, lacks flexibility, is difficult to operate, and is not conducive to functional training. . Contents of the invention [0003] The purpose of the present invention is to provide a coronal deformity control orthosis of the ankle joint, which solves the problem that the traditional orthosis for correcting varus or valgus deformity of the foot and ankle is complex and bulky in structure, does not have the function of rapid stretching and valgus deformity correction, Lack of dexterity, operational difficulties, technical problems that ...
