Ankle rehabiliation apparatus with double-freedom degree

Abstract

The invention relates to an ankle rehabilitation apparatus with two degrees of freedom, comprising a support. The invention is characterized in that a zigzag rod which can turn and swing around a D / P axis is hinged between the left part and the right part of the support; the zigzag rod is hinged with a sole supporting sheath facing the negative direction of a P / S axis via a hinge hole so as to lead the sole supporting sheath to turn and swing around the P / S axis. The support is also provided with a first motor drive mechanism and a second motor drive mechanism; the first motor drive mechanism and the second motor drive mechanism are used for driving the zigzag rod and the sole supporting sheath to carry out to-and-fro turning and swinging. By using the second motor drive mechanism to drive the sole supporting sheath to carry out to-and-fro turning and swinging, the invention realizes varus and eversion of the ankle, and by using the first motor drive mechanism to drive the zigzag rod to carry out to-and-fro turning and swinging, the invention realizes abduction and adduction of the ankle. The rehabilitation apparatus has simple structure, convenient use, low manufacturing cost, easy marketization and broad application prospect.

Description

Technical field: [0001] The invention relates to a medical device, in particular to a two-degree-of-freedom ankle rehabilitation device for ankle rehabilitation. Background technique: [0002] Ankle sprains are the most common sports injuries, most of which are caused by losing the center of gravity of the body, stepping on someone else's foot when landing or tripping over the foot. When a sprain occurs, local joint swelling and pain will occur, and in severe cases, it may even cause fractures. The effective rehabilitation treatment method is to massage the ankle. At the beginning, the massage treatment was performed by professional doctors, which brought huge labor to the doctors. Strength, since then there have been some automated ankle rehabilitation instruments at home and abroad, such as an ankle rehabilitation instrument abroad, which is supported by four retractable air pressure rods. Different ankle rehabilitation actions can be realized by simulation, but the contr...

When a sprain occurs, local joint swelling and pain will occur, and in severe cases, it may even cause fractures. The effective rehabilitation treatment method is to massage the ankle. At the beginning, the massage treatment was performed by professional doctors, which brought huge labor to the doctors. Strength, since then there have been some automated ankle rehabilitation instruments at home and abroad, such as an ankle rehabilitation instrument abroad, which is supported by four retractable air pressure rods. Simulation can realize different ankle rehabilitation actions, but the control system of this mechanism is complex and the manufacturing cost is high, which is not conducive to widespread use
