Ankle multidimensional regulation-control orthosis

Abstract

An ankle multidimensional regulation-control orthosis 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 U-shaped hole ring arranged at the calcaneus, a near end hole full ring arranged at the middle section or middle upper section of a tibia, and a plurality of fast extending lengthening rods which are connected between the far end U-shaped hole ring and the near end hole full ring; each fast extending lengthening rod comprises a thread rod, an inner rod sleeve and an outer rod sleeve; a pressure controller is arranged between the upper end part of the inner rod sleeve and the thread rod; a locking joint is arranged between the upper end part of the outer rod sleeve and the inner rod sleeve. The ankle multidimensional regulation-control orthosis can perform treatment tasks such as traction, resetting, fixing and deformity correcting on the fracture or deformity of the angle in a multidimensional space, the treatment on multiple bone diseases of the angle can be realized, particularly, flexible correcting can be realized on rotary deformity, strephexopodia and strephenopodia, and the orthosis plays an important role in foot correcting aspect and has obvious advantages.

Description

technical field [0001] The invention relates to a bone external fixator, in particular to an ankle multi-dimensional control orthosis for treating complex ankle fractures and ankle deformities. Background technique [0002] Ankle deformities can be clinically defined as deformities such as angulation, rotation, displacement, and length; in terms of subdimensional space, they can be defined as multidimensional subspace deformities, such as abnormalities in two, three, four or more dimensions. Rotation and displacement deformities are measured in angles; displacement and length deformities are both displacement deformities and are measured in distances. Ankle orthosis is to change the angular displacement of the deformed angle so that it is parallel or perpendicular to the normal anatomical axis. Therefore, the correction of ankle deformities can be corrected by applying the principle of multidimensional control. Angular deformities on different sides are two-dimensional def...

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-dimensional control orthosis for the ankle joint, which solves the problem that the traditional external fixator for the treatment of complex ankle fractures and ankle deformities has complex structure, simple function, inconvenient operation, and is difficult to meet the needs of complex ankle joints.
