Description

Technical Field

[0001] The utility model belongs to the technical field of rehabilitation training equipment and relates to a rehabilitation appliance, in particular to an ankle joint rehabilitation training device. Background Art

[0002] During the long-term treatment and recovery process of paraplegic patients, they may develop muscle atrophy, foot drop and thrombosis problems. Ankle joint activities can effectively prevent muscle atrophy, foot drop and thrombosis problems. In addition, there is a long period of fixation after ankle surgery. If patients do not actively perform ankle joint activity training during the recovery period, joint adhesion and stiffness are likely to occur.

[0003] In reality, most paraplegic patients can only passively move their ankle joints. Some patients rarely move even if they can, which results in insufficient ankle joint movement. Patients who have undergone ankle surgery are afraid of the light or heavy movements caused by external forces, and are less willing to accept passive movements. Medical staff or family members who perform ankle joint movements on patients not only have a large workload, but they may also be too busy to allow the patient to move their ankle joints for a long time or irregularly.

[0004] To this end, medical personnel have designed various ankle rehabilitation training devices to assist patients in conducting ankle rehabilitation training by themselves, such as an ankle mobilizer with application number 202120085017.7 invented by medical personnel of our hospital, which includes a load-bearing plate, a rotating plate is hinged on the left side of the top of the load-bearing plate, a foot fixing belt is fixedly connected to the right side wall of the rotating plate, a pulling belt is installed on the top of the rotating plate, and a pulling handle is fixedly connected to the right end of the pulling belt. In this ankle mobilizer, the patient can hold the pulling handle and pull the rotating plate to rotate through the pulling belt. When the rotating plate rotates, the patient's foot can be pulled to rotate, thereby driving the patient's ankle to move. The patient can also use the strength of his own feet to pull the rotating plate to rotate, thereby exercising the patient's ankle and the patient's calf muscles, so that the patient's ankle activities can be carried out autonomously, which can not only achieve the effect of exercise, but also be controlled by the patient himself, avoiding excessive or insufficient force when moving the ankle, not only can the ankle joint be effectively moved, but also excessive force can be prevented from damaging the ankle joint.

[0005] During use, patients found that the technical solution has the following defects: on the one hand, a considerable number of patients have difficulty completing the training by themselves due to upper body movement difficulties, and still need assistance from family members or medical staff. Although the workload has been reduced, it still takes a lot of time; on the other hand, the range of motion is not easy to control accurately during manual operation, and the intensity of the training may change from time to time, which is not conducive to recovery.

[0027] like Figure 1 , Figure 2As shown, an ankle joint rehabilitation training device described in the utility model includes a fixed base plate 1 and a movable push plate 2. The lower end of the movable push plate 2 is hingedly connected to the surface of the fixed base plate 1, and the movable push plate 2 can swing back and forth around the hinge at its lower end. An electric push rod 3 is also provided between the movable push plate 2 and the fixed base plate 1. The lower end of the electric push rod 3 is hingedly connected to the fixed base plate 1 through a push rod bracket 101, and the upper end is hingedly connected to the upper part of the movable push plate 2. The movable push plate 2 can be pushed to swing back and forth by retracting the electric push rod 3; the electric push rod 3 is controlled by a control panel 9.

[0028] A protractor 5 is also provided on one side of the movable push plate 2. The protractor 5 is installed with its arc surface facing downward. The protractor 5 is stationary relative to the fixed bottom plate 1 and its straight edge remains horizontal. An indicator needle 6 is also provided on the outside of the protractor 5. The indicator needle 6 is fixed relative to the movable push plate 2 and can move synchronously with the movable push plate 2. The lower end of the indicator needle 6 is in the shape of a pointer. Before the start of rehabilitation training, the movable push plate 2 can be controlled to swing slowly, and the limit position that the patient can bear can be measured by the indicator needle 6. During rehabilitation training, the movable push plate 2 is set to swing within this range.

[0029] The indicating needle 6, the protractor 5 and the movable push plate 2 are coaxially mounted, and the axis is a fixed axis.

[0030] A fixing sleeve 4 is provided at the end of the indicator needle 6, and the fixing sleeve 4 is installed and fixed on the side of the movable push plate 2. The end of the indicator needle 6 is inserted into the fixing sleeve 4 to realize the end positioning; at the same time, a fixing boss 7 is also provided on the side of the movable push plate 2, and the fixing boss 7 is connected and fixed to the movable push plate 2. The fixing sleeve 4 and the fixing boss 7 are used to jointly support the indicator needle 6 outward, reserving the installation position of the protractor 5; a positioning groove 701 is provided on the fixing boss 7, and the middle section of the indicator needle 6 is stuck in the positioning groove 701 to realize the middle section positioning of the indicator needle 6, so that the indicator needle 6 will not swing to both sides.

[0031] The protractor 5 can be fixedly installed horizontally on the side of the fixed base plate 1, or can be fixedly connected to the axis of the push plate bracket 102 at the lower end of the movable push plate 2 and kept horizontal, or can be suspended on the axis beyond the push plate bracket 102 with a larger installation hole.

[0032] The fixed bottom plate 1 is provided with a push rod bracket 101 , and the lower end of the electric push rod 3 is mounted on the push rod bracket 101 and is hingedly connected to the push rod bracket 101 . When the electric push rod 3 is working, the lower end rotates slightly on the push rod bracket 101 .

[0033] Balance wings 501 are respectively provided at both ends of the protractor 5. When the protractor 5 is suspended, the balance wings 501 help the protractor 5 to maintain balance and extend the length of the straight edge of the protractor 5, making it easier to calibrate manually.

[0034] The action of the electric push rod 3 is controlled by the circuit, such as Figure 3 As shown, S1 is the main switch, K is the forward and reverse switch, and M is the motor.

[0036] The movable push plate 2 is also provided with a fixing hole 201 , which is a vertical strip hole used for fixing the belt for installation.

[0037] Example

[0038] Take the rehabilitation training of patients with ankle injuries as an example. Figure 1-2 As shown, before use, first pass the fixing belt through the fixing hole 201 in the middle of the movable push plate 2 to fix the patient's foot to the movable push plate 2. Start the main switch S1, connect the DC power (not shown in the figure), start the manual mode through the control panel 9, and control the movable push plate 2 to drive the patient's foot to bend backward until the patient feels pain, read the protractor 5 reading and record it; then control the movable push plate 2 to stretch forward until the patient feels pain, read the protractor 5 reading and record it. Repeat the above process 3-5 times, and take the minimum value as the swing angle range value of the current training.

[0039] The swing angle of the movable push plate 2 is set between the minimum values ​​through the control panel 9, the training time is set, the automatic mode is started, and the timed long ankle joint rehabilitation training begins.

[0040] When the set time comes, the training stops automatically, and the medical staff separates the patient's foot from the movable push plate 2 to complete one training. After repeated training, the swing angle that the patient's ankle joint can withstand will gradually increase. When the patient's tolerable angle no longer increases or there is no obvious pathological pain, it means that the patient's ankle joint injury has been completely healed.
