Description

TECHNICAL FIELD

[0001] The utility model relates to the field of rehabilitation technology, especially to a knee joint postoperative walking and rehabilitation integrated device. BACKGROUND

[0002] The knee joint rehabilitation training method is a systematic and progressive process, which can promote the recovery of knee joint function, enhance the surrounding muscle strength and improve the joint stability through knee joint flexion and extension exercise, muscle strength training, balance and stability training, flexibility training and functional activity exercise.

[0003] When the patient performs active flexion and extension exercise of the knee joint after the knee joint surgery, the knee joint of the patient is in a long-term fixed state and cannot be moved, so it is necessary to drive the knee joint to perform flexion and extension exercise by external force in the early stage of rehabilitation, and then gradually increase the load as the recovery of the knee joint progresses. However, the existing knee joint postoperative walking and rehabilitation integrated device can only adjust the load required for knee joint flexion and extension, and cannot drive the knee joint to perform forced flexion and extension exercise in the early stage of rehabilitation. Therefore, the patient needs to perform initial rehabilitation through other rehabilitation devices before using the knee joint postoperative walking and rehabilitation integrated device for subsequent rehabilitation, which is inconvenient for the patient to use. Therefore, the present application provides a knee joint postoperative walking and rehabilitation integrated device to meet the needs. UTILITY MODEL CONTENTS

[0004] The technical problem to be solved by the utility model is to provide a knee joint postoperative walking and rehabilitation integrated device. By arranging an elastic assembly, the knee joint postoperative flexion and extension exercise of the patient in each stage can be assisted. In the early stage of rehabilitation flexion and extension exercise, the knee joint can be forced to perform flexion and extension exercise. In the later stage of rehabilitation flexion and extension exercise, flexion and extension resistance can be provided to increase the load of the knee joint flexion and extension connection, thereby improving the rehabilitation exercise effect of the patient. At the same time, when the patient walks, the patient can be assisted to stand, so as to solve the problem that the existing knee joint postoperative walking and rehabilitation integrated device cannot force the knee joint to flex and extend in the early stage of rehabilitation.

[0005] To solve the above technical problems, the utility model provides the following technical scheme:

[0006] A knee joint postoperative walking and rehabilitation integrated device, comprising a first support and a second support, the outer wall of the first support and the second support is rotatably connected with a connecting plate, the outer wall of the first support and the second support is fixedly connected with a half gear, two half gears are meshed with each other;An elastic assembly is used for assisting the patient to perform knee joint flexion and extension exercise, and the elastic assembly is connected with the first support and the second support.

[0007] Optionally, the elastic assembly comprises an elastic band fixedly connected inside the first support, and one end of the elastic band away from the first support is fixedly connected with a spiral piece.

[0008] Optionally, the inside of the spiral piece is slidably connected with a rotating piece, and the outer wall of the rotating piece is fixedly connected with a plurality of stop blocks.

[0009] Optionally, the outer wall of the stop block is sleeved with a sleeve, and the number of the sleeve is two, and the two sleeves are arranged on the two sides of the second support.

[0010] Optionally, the rotating piece is inserted into the inside of the sleeve, and the spiral piece is rotatably connected in the inside of the sleeve.

[0011] Optionally, the overall contour of the spiral piece is a spiral contour, and the elastic band is spirally wound on the outer wall of the spiral piece.

[0012] Optionally, one side of the sleeve is provided with a strip-shaped groove, and the elastic band is inserted into the strip-shaped groove of the sleeve.

[0013] Optionally, the number of the sleeve is two, and the outer wall of one of the sleeves is fixedly connected with a plug rod, and the inside of the other sleeve and the corresponding spiral piece is provided with a plug groove.

[0014] Optionally, the outer wall of the plug rod is sleeved with a first limiting block, and the first limiting block is fixedly connected to the outer wall of the second support.

[0015] Optionally, the inside of the plug groove is inserted with a second limiting block, and the second limiting block is fixedly connected to the outer wall of the second support, and the size of the plug rod and the plug groove is matched.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above scheme, by setting the elastic assembly, the knee joint of the patient after the operation can be assisted in each stage of flexion and extension exercise, in the early stage of rehabilitation flexion and extension exercise, the knee joint can be forced to flex and extend, in the later stage of rehabilitation flexion and extension exercise, flexion resistance can be provided, the load of knee joint flexion and extension connection is increased, and then the rehabilitation exercise effect of the patient is improved, and the patient is assisted in standing when walking.

[0018] By setting the matching plug rod and plug groove, different effects can be achieved in different states of the device. When it is in a state that needs to force the knee joint flexion and extension exercise, the corresponding plug rod and plug groove on the two sleeves can be docked together, so that the two sleeves are connected together through the plug rod and plug groove. Since the plug rod and plug groove are matched, a certain friction clamping force will be generated after the plug rod and plug groove are docked together, which has a certain fixing effect on the two sleeves, facilitating the patient to pull the sleeve. When it is in a state of increasing flexion and extension exercise load, the tension of the rubber band on the screw member will be transmitted to the sleeve, so that the sleeve is fixed on the corresponding first limiting block and second limiting block through the corresponding plug rod and plug groove, so that the sleeve will not fall off, improving the fixing effect of the sleeve.

[0019] By setting the screw member, when the rubber band is wound on the screw member, the spiral contour of the screw member will have a guiding and limiting effect on the rubber band, making the winding of the rubber band more uniform, facilitating the use of the patient. At the same time, the strip-shaped groove on the sleeve can cooperate with the screw member to wind the rubber band, and when the rubber band is separated from the screw member, the rubber band can slide along the inside of the strip-shaped groove of the sleeve and will not be limited and blocked, facilitating the rubber band to separate from the inside of the sleeve.
