Abstract

The invention relates to a repositioning and fixed bone structure orthosis, which includes a leg guard and a foot pad in a fixed connection state for the patient's legs and feet respectively. The bottom surface of the foot pad is provided with a number of support columns. And a support structure is formed between the bottom surface of the foot pad and the road surface through the support pillars. The support pillars are telescopic structures. A linkage mechanism is provided between a plurality of the support pillars. After some of the support pillars are compressed and contracted, The other support columns are extended through the linkage mechanism. According to this technical solution, when the foot pads are on a sloping road surface and the foot pads keep moving downward horizontally, some of the support columns will first come into contact with the road surface, and will be compressed and contracted to reduce their length, while the other part of the support columns will increase due to extension. The length allows the contact surface formed by the lower ends of the multiple support columns to fit as closely as possible with the tilted state of the ground when the foot pad is kept horizontal to form an effective support.

Description

Reduction and fixation of bone structure orthosis

Technical field

The invention relates to the technical field of medical devices, and in particular to an orthosis for resetting and fixing bone structures.

Background technique

Orthopedic orthotics refers to the general term for external devices assembled on the limbs, trunk and other parts of the human body. Its purpose is to prevent or correct deformities of the limbs and trunk or to treat bone, joint and neuromuscular diseases and compensate for their functions.

Among them, the main function of lower limb orthotics is to support body weight, assist or replace limb functions, limit unnecessary activities of lower limb joints, maintain lower limb stability, improve posture when standing and walking, and prevent and correct deformities.

Current lower limb orthotics are mainly composed of leg guards and foot pads made of hard materials. In order to keep the patient's ankle joint in a fixed state, the leg guards and foot pads usually use fixed angles. After the patient wears it, use the binding strap to place the patient's heel against the connection angle between the leg guard and the foot pad, and then fix the leg and foot to the leg guard respectively. and foot pads to keep the patient's legs and feet in a fixed state;

During walking, since the patient's ankle joint is in a fixed state, it cannot rotate. In order to maintain effective support with the ground during walking, the foot pad will try to remain parallel to the ground when it is in contact with the ground. When going uphill or downhill and causing the road surface to slope, because the patient's ankle joint is in a fixed state, it will be difficult to adjust the angle when the foot pad is in contact with the ground, that is, it is difficult to make the foot pad in parallel contact with the ground. The state is used to support the patient;

In order to reduce the impact caused by the slope of the road surface, patients usually walk sideways. However, walking sideways not only makes walking inconvenient, but also the two sides of the foot pads cannot keep fit with the road surface, which can only reduce the impact of the road surface. role.

To this end, the inventor proposes an orthosis that can automatically adjust the support state between the foot pad and the road surface according to the flatness of the road surface.

Contents of the invention
