Embodiment Construction

[0050] Below in conjunction with accompanying drawing, the usage mode and the method of inventive device are described further:

[0051]1 in the figure is the main body, the front block structure bottom surface 2 and the front outer unit block 3 form the front block structure area. Front outer unit block 3 is from top to bottom, the size is from small to large, and the gap is distributed from large to small hexagonal unit blocks, and its thickness is about 3mm. When the user's knee joint is stretched backward to about 5° and the knee joint is in a flexed state, the gap between part of the front outer unit blocks 3 will shrink and start to produce contact extrusion, which will produce a small deformation resistance; As the movement proceeds, the deformation of the bottom surface 2 of the front block structure continues to occur, and more front outer unit blocks 3 will be concentrated towards the center, and the force generated by the extrusion of the unit blocks against continu...

Abstract

The invention discloses an in-vitro orthopedic device and a preparation method thereof. The in-vitro orthopedic device comprises an orthopedic main body, a front orthopedic surface and a rear orthopedic surface, wherein the orthopedic main body is in a hollow cylinder shape, openings are formed in the front surface, the rear surface, the left surface and the right surface of the orthopedic main body, and the front orthopedic surface and the rear orthopedic surface are arranged in the front opening and the rear opening of the orthopedic main body respectively. A front blocky structure bottom surface and front outer side unit blocks form a front blocky structure area. The front outer side unit blocks are hexagonal unit blocks which are distributed from top to bottom, from small to large in size and from large to small in gaps, and when the knee joint of a user stretches backwards and is in a bent state, the gaps between part of the front outer side unit blocks can be shrunk to start to generate contact extrusion, and tiny deformation resistance can be generated. According to the blocky structure, gradual change of rigidity is achieved by adjusting the gaps between the front outer side unit blocks.

Description

technical field [0001] The invention belongs to the technical field of orthopedic devices, in particular to an external orthopedic device and a manufacturing method thereof. Background technique [0002] In the orthopedic process of knee hyperextension and other limb dysplasia, orthotics are widely used in knee hyperextension problems because they can effectively limit the abnormal motion and action of the knee joint. However, the existing orthotics are inconvenient to wear, poor in individual adaptability, complicated in customization process, time-consuming, inconvenient in limb movement due to heavy weight, and ugly in appearance, leading to reluctance to wear them, which affects the treatment effect. Contents of the invention [0003] The object of the present invention is to provide an extracorporeal orthopedic device and its manufacturing method, so as to solve the above problems. [0004] To achieve the above object, the present invention adopts the following techn...
