Problems solved by technology

However, in clinical practice, most of this kind of rehabilitation training relies on physical therapists to provide one-on-one physical therapy to patients. The method is single, time-consuming and laborious, and lacks quantitative and objective evaluation.
[0003] Existing ankle joint rehabilitation equipment mostly adopts a parallel mechanism, which has a small range of motion and complex control

Embodiment Construction

[0016] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0017] combine Figure 1~4 , the present invention includes a pedal 1, a sagittal axis motor 2, a sagittal axis bracket 3, a sagittal axis shaft 4, a coronal shaft shaft 5, a coronal shaft motor 6, a coronal shaft bracket 7, a vertical shaft shaft 8, a base 9, Vertical axis motor 10, control box 11, force sensor 12.

[0018] The pedal 1 is installed on the sagittal axis bracket 3 through the sagittal axis rotating shaft 4, and the sagittal axis motor 2 is installed on the sagittal axis bracket 3, and is connected with the rotation axis 4 of the pedal through a key, and the rotation of the motor drives the pedal The plate rotates to achieve plantar flexion and dorsiflexion of the ankle joint. In order to ensure that the ankle joint of the human foot is coaxial with the axis of rotation, the foot pedal is located below the axis of rotation of the sagittal axis.

Abstract

The invention provides active and passive type ankle joint rehabilitative apparatus which uses orthogonal coordinates and three degrees of freedom to respectively achieve dorsal stretch and plantar flexion, inversion and eversion, and intorsion and extorsion motions of ankle joints. Every degree of freedom is respectively driven by a motor so that single degree of freedom motions of ankle joints are achieved and the linkage of three motor can achieve complex motions of ankle joints. Force sensors are arranged on pedals of the ankle joint rehabilitative apparatus. During a rehabilitation process, foot motions of a trainee are controlled by detecting stresses of the pedals so that active and passive type ankle trainings are achieved, besides, stress safety protections are performed and secondary injuries to the trainee are avoided. The active and passive type ankle joint rehabilitative apparatus meets rehabilitative training requirements of single degree of freedom and multiple degrees of freedom motions of ankle joints with a simple and reliable structure. Intelligent control, effect evaluation and intelligent protection are achieved due to an adoption of force sensors so that effects and safety of rehabilitative trainings of a patient are guaranteed.

Description

technical field [0001] The invention relates to a medical and health care device, specifically an ankle joint rehabilitation device. Background technique [0002] Ankle joint injuries are relatively common in people's daily life. Ankle joint injuries may occur in sports activities and ordinary life. Ankle joint injuries not only bring pain to patients physically, but also seriously interfere with people's normal life. , more seriously even affect people's mental health. Most patients with ankle joint injuries need physical rehabilitation training during the medical treatment process to prevent muscle atrophy and restore ankle joint function. However, in clinical practice, most of this kind of rehabilitation training relies on one-on-one physical therapy provided by physiotherapists to patients. The method is single, time-consuming and laborious, and lacks quantitative and objective evaluation. [0003] Existing ankle joint rehabilitation equipment mostly adopts a parallel ...
