Description

Technical Field

[0001] The utility model relates to a rehabilitation device, in particular to a rehabilitation device for postoperative osteoarticular joints. Background Art

[0002] After leg surgery, the rehabilitation training of the gastrocnemius muscle is an essential part of the recovery process. As the main muscle on the back of the calf, the gastrocnemius muscle plays a crucial role in daily activities such as walking, jumping, and running. After surgery, the gastrocnemius muscle may lose its original strength and flexibility due to long-term fixation or lack of activity. Therefore, it is crucial to restore its function through rehabilitation training.

[0003] In the initial stage of rehabilitation training, patients may be unable to perform high-intensity activities due to postoperative pain or discomfort. At this time, doctors or rehabilitation therapists will guide patients to perform some mild passive activities, such as gently flexing and extending the ankle joint, rotating the calf, etc., to promote blood circulation and prevent muscle atrophy and joint stiffness.

[0004] As the wound heals and the pain subsides, patients can gradually start active activities. These activities include gradually increasing the range of flexion and extension of the ankle joint, performing calf raising exercises, etc. These active activities help to enhance the strength and flexibility of the gastrocnemius muscle and lay a solid foundation for its subsequent rehabilitation training.

[0005] However, long-term rehabilitation training may cause fatigue and tension in the gastrocnemius muscle. To relieve this discomfort, it is very necessary to massage and relax the gastrocnemius muscle. Massage can not only promote blood circulation in the gastrocnemius muscle, accelerate the excretion of metabolic waste, but also relieve muscle tension and improve muscle softness.

[0006] Therefore, the utility model proposes a device for massaging the training muscle groups after osteoarticular joint surgery. Content of the Utility Model

[0007] In order to overcome the shortcoming that the existing rehabilitation device only assists postoperative patients to make rehabilitation movements but fails to massage and relax the training muscle groups, the utility model provides a rehabilitation device for postoperative osteoarticular joints with a massage function.

[0008] A rehabilitation device for postoperative osteoarticular joints includes a rehabilitator. The rehabilitator is provided with a leg placement area. A fixing rod is connected to the side of the placement area. The fixing rod is connected with a mounting frame. A servo motor is fixed on the mounting frame. The end of a massage roller is connected with a bearing, and the bearing is located in the fixing rod. The output shaft of the servo motor supplies energy to the massage roller. The massage rollers are symmetrically arranged. The end of the massage roller is connected with a sprocket, and a belt is sleeved outside the sprocket for transmission.

[0009] In one embodiment, there is also a convex shaft, and a convex shaft made of soft rubber material axially is arranged outside the massage roller.

[0010] In one embodiment, there are also a connecting rod and a threaded rod. The connecting rod connects the bearings on the same side, and the bearings are rotatably connected to the connecting rod. The threaded rod is threadedly connected to the connecting rod, and the end of the threaded rod is rotatably connected to the fixed rod.

[0011] In one embodiment, a turntable is arranged at the upper end of the threaded rod, and a holding groove is formed in the turntable.

[0012] In one embodiment, there is also a return spring, which is connected between the fixed rod and the connecting rod. The return spring can increase the friction coefficient between the threaded rod and the connecting rod and improve the stability of the connecting rod.

[0013] In one embodiment, there is also a scale ruler, which is located on the fixed rod and can mark the height of the connecting rod.

[0014] In one embodiment, there is also a protective housing, which is fixed outside the servo motor.

[0015] In one embodiment, there is also a foam pad, which is arranged on the convex shaft.

[0016] Beneficial effects: After corresponding rehabilitation training, patients after bone and joint surgery can lie flat on the rehabilitator, then place their legs in the placement area of the rehabilitator, turn on the servo motor to drive the massage roller to rotate, and the massage roller will massage the gastrocnemius muscle of the patient, achieving the purpose of improving the rehabilitation training effect.

Detailed implementation mode

[0022] The present utility model will be further described in detail below in conjunction with the attached drawings and specific implementation modes, but the protection scope and application scope of the present utility model are not limited.

[0023] Embodiment 1

[0024] A rehabilitation device for use after bone and joint surgery, as Figures 1-4 shown, includes a rehabilitator 1. The rehabilitator 1 is provided with a leg placement area. A fixing rod 2 is connected to the side of the placement area. The fixing rod 2 is connected to a mounting frame 3. A servo motor 4 is fixed on the mounting frame 3. One end of a massage roller 5 is connected with a bearing 501, and the bearing 501 is located inside the fixing rod 2. A protective housing 14 is fixed outside the servo motor 4. The output shaft of the servo motor 4 supplies energy to the massage roller 5. Axial convex shafts 8 made of soft rubber material are arranged outside the massage roller 5. A foam pad 15 is arranged on the convex shafts 8. The massage rollers 5 are symmetrically arranged. One end of the massage roller 5 is connected with a sprocket 6, and a belt 7 is sleeved outside the sprocket 6 for transmission.

[0025] As Figure 1 、 Figure 3 and Figure 4 shown, it further includes a connecting rod 9 and a threaded rod 10. The connecting rod 9 connects the bearings 501 on the same side, and the bearing 501 is rotatably connected to the connecting rod 9. The threaded rod 10 is threadedly inserted through the connecting rod 9, and the end of the threaded rod 10 is rotatably connected to the fixing rod 2. A return spring 13 is connected between the fixing rod 2 and the connecting rod 9. The return spring 13 can increase the friction coefficient between the threaded rod 10 and the connecting rod 9 and improve the stability of the connecting rod 9. A scale 12 is located on the fixing rod 2, and the scale 12 can mark the height of the connecting rod 9. A turntable 11 is arranged at the upper end of the threaded rod 10, and the turntable 11 is provided with a holding groove, which is convenient for the staff to adjust the turntable 11.

[0026] Working principle: After the patient after bone and joint surgery undergoes corresponding rehabilitation training, he can lie flat on the rehabilitator 1, and then place the legs on the placement area of the rehabilitator 1. The placement area is equipped with straps to fix the patient's legs. Then, the servo motor 4 is started to drive the massage roller 5 to rotate. The massage roller 5 will massage the gastrocnemius muscle of the patient to achieve the purpose of improving the rehabilitation training effect. According to the different body structures of the patients, the height of the massage roller 5 can be adjusted. Specifically, by rotating the turntable 11, the threaded rod 10 is driven to rotate. The threaded rod 10 will lift the connecting rod 9 upward, and the connecting rod 9 will drive the bearing 501 and the massage roller 5 to move upward, thereby being able to adjust the contact force between the massage roller 5 and the patient's gastrocnemius muscle and adjust the massage intensity accordingly.
