Technical Field

The utility model belongs to the field of medical rehabilitation auxiliary devices, concretely relates to ankle joint fracture postoperative auxiliary patient carries out early function exercise's rehabilitation device.

Background

Early, effective ankle joint functional training is crucial to the functional recovery of ankle joint fracture postoperative patient. For ankle fractures, including simple external ankle fractures, internal and external ankle fractures, and three-ankle fractures, the commonly adopted treatment is a resection reduction internal fixation operation. The advantages of this method of treatment are anatomical reduction of the fracture, early functional exercise and early walking to work. External fixations such as plaster and splint have the disadvantage of lacking early functional exercises, often resulting in flexion and extension dysfunction of the ankle. For patients with open reduction internal fixation, it is common practice to exercise the function in the case of pain tolerance on the second day after surgery.

Due to factors such as pain and psychology, active functional exercise of the ankle joint is difficult to perform in the early stage, and passive functional exercise is particularly important. The early passive functional exercise can be performed by means of accompanying help, and the patient himself or herself can be assisted by means of bandages and the like. The accompanying help requires additional employment of professional accompanying personnel or assistance of family members, which is labor-consuming and laborious. The tools such as bandages, cloth belts and the like have poor stretching performance, and often need a patient to sit up or be assisted by accompanying and nursing, and the patient is sleeved on the arch part and is easy to slip. Meanwhile, bandages and the like have poor fit with the arch of foot, and patients feel uncomfortable.

Therefore, the adjustable and assembled ankle joint function exercise assisting device is expected to solve the above problems encountered by early function exercise after ankle joint fracture surgery, help patients to obtain effective function exercise in early stage, and enable the ankle joint function to be recovered effectively to the maximum extent.

Compared with the prior art, the beneficial effect of this apparatus is:

1. the instrument has simple structure and low processing and manufacturing cost.

2. Economical and practical, the patient can wear the device conveniently, and the patient can conveniently carry out the training of the flexion and extension functions of the bare joint in various body positions such as sitting, lying on the back and the like.

3. During function training, the soles of the feet of a patient are arranged on the bottom plate, the small feet and the bare joints are attached to the rear foot oversleeves, the two shank fixing bands and the two sole fixing bands are fixed on the small feet and the soles through nylon buttons respectively, the patient hooks the lifting holes of the two forefoot lifting straps by using the pulling hooks of the lifting rods, then the bare joint flexion and extension rehabilitation training is carried out, the soles, the bare joints and the shanks are always in relatively fixed positions in the lifting operation process, and the bare joints are prevented from being misplaced in the training.

This ankle joint function exercise assistor has solved the above-mentioned difficult problem that early function exercise of ankle joint fracture postoperative met, and the help patient obtains effectual function exercise early for the ankle joint function obtains maximum effective rehabilitation.
