Description

Technical Field

[0001] This utility model relates to the technical field of joint-assisted rehabilitation devices, and in particular to a joint-assisted rehabilitation device. Background Technology

[0002] A joint-assisted rehabilitation device is a medical device used to assist joint movement and promote rehabilitation, primarily targeting joint mobility impairments caused by surgery, injury, arthritis, stroke, or neuromuscular diseases. After joint surgery or severe injury, early mobilization can effectively prevent adhesions and stiffness, but patients often find it difficult to move independently due to pain or muscle weakness. In such cases, this device can provide external assistance, helping patients perform regular activities within a safe range.

[0003] However, these devices are mostly made of sponge pads or rubber, lacking breathability. In summer, they can easily cause stuffiness and sweating, potentially triggering adverse reactions such as skin allergies or eczema. The parts that come into contact with the skin easily accumulate sweat and are difficult to disinfect thoroughly, increasing the risk of cross-infection, which is particularly significant for patients whose postoperative wounds have not fully healed. Furthermore, these standard devices are often unsuitable for people with specific body types, such as obese patients or children.

[0004] Therefore, this application provides a joint-assisted rehabilitation device to solve the problems mentioned in the background art. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 , Figure 2 , Figure 4 This utility model provides an embodiment of a joint-assisted rehabilitation device, comprising a drive device 1, a thigh placement device 2, a calf placement device 3, and two wire mesh bodies 4. The drive device 1 includes a device housing 101. A first electric telescopic rod 102 is fixedly disposed in the middle of the inner rear wall of the device housing 101. A traction rod 103 is fixedly connected to the output end of the first electric telescopic rod 102. A first fixing seat 104 is fixedly disposed on the upper end face of the traction rod 103. A rotating shaft 105 is fixedly disposed on the upper end face of the rear end of the outer wall of the device housing 101. A first connecting ring 203 is rotatably disposed in the middle of the first fixing seat 104 by a pin, and the end of the pin is provided with a radial through hole. A cotter pin passes through the radial through hole and is bent in both directions to form an axial limiting structure. A housing top cover 106 is fixedly disposed on the upper end face of the device housing 101. A slot 107 is opened on the upper end face of the housing top cover 106 near the front end, and the traction rod 103 moves linearly back and forth inside it.

[0029] Specifically, the output end of the first electric telescopic rod 102 drives the traction rod 103 to move the first movable rod 201 back and forth in a reciprocating cycle. When the device is started, the rotating block 303 moves the front end of the second movable rod 301 up and down around the rotating shaft 105.

[0030] Reference Figure 2 , Figure 5 The thigh placement device 2 includes a first movable rod 201. A second fixed seat 202 is fixedly installed at the rear end of the outer wall of the first movable rod 201. A first connecting ring 203 is fixedly installed near the front end of the lower end face of the first movable rod 201. A second electric telescopic rod 204 is fixedly installed on both sides of the outer wall of the first movable rod 201 near the front and rear ends. The output ends of two second electric telescopic rods 204 on the same side of the four second electric telescopic rods 204 are fixedly connected to a first support frame 205. Hooks 206 are fixedly installed at two corners near the upper end face of one side of the outer wall of the two first support frames 205. Two wire mesh bodies 4 are fixedly connected to the upper end faces of the first support frame 205 and the second support frame 305 respectively through the snap-fit ​​of the hooks 206 and the buckles 403.

[0031] Specifically, driven by multiple second electric telescopic rods 204, the first support frames 205 on both sides move linearly to the sides, increasing the internal distance of the thigh placement device 2 to accommodate patients of different body types. The hinged arrangement between the second fixing seat 202 and the second connecting ring 302 better simulates the scenario of knee joint movement.

[0032] Reference Figure 3 , Figure 6The calf placement device 3 includes a second movable rod 301. A second connecting ring 302 is fixedly installed at the front end of the outer wall of the second movable rod 301. A rotating block 303 is fixedly installed at the rear end of the outer wall of the second movable rod 301. A third electric telescopic rod 304 is fixedly installed at the front and rear ends of both sides of the outer wall of the second movable rod 301. A second support frame 305 is fixedly connected to the output ends of the two third electric telescopic rods 304 on the same side. A hook 206 is fixedly installed at the two corners of the upper end face of one side of the outer wall of the two second support frames 305. The second connecting ring 302 is rotatably installed in the middle of the second fixed seat 202 through a pin shaft. The end of the pin shaft is provided with a radial through hole. The cotter pin passes through the radial through hole and bends in both directions to form an axial limiting structure. The rotating shaft 105 is rotatably installed in the rotating groove opened at the rear end of the rotating block 303.

[0033] Specifically, driven by multiple third electric telescopic rods 304, the second support frames 305 on both sides move linearly to the sides, increasing the internal distance of the lower leg placement device 3 to accommodate patients with different body shapes. The connection points between the rotating block 303 and the rotating shaft 105 are on both sides, which can effectively prevent the patient's body from being pinched and causing secondary trauma.

[0034] Reference Figure 2 , Figure 7 Both wire mesh bodies 4 include nylon wire mesh 401. Wire mesh fixing frames 402 are fixedly installed on both sides of the nylon wire mesh 401. Buckles 403 are fixedly installed at the corners on one side of the lower end faces of the two wire mesh fixing frames 402.

[0035] Specifically, the nylon mesh 401 has high strength, good abrasion resistance, chemical resistance, water resistance, and elasticity. The mesh fixing brackets 402 on both sides of the nylon mesh 401 can effectively prevent deformation and disintegration. The mesh can be removed from the hook 206 by the buckle 403 for quick cleaning and disinfection.

[0036] Working principle: When a patient needs to use the device, the two cleaned and disinfected wire mesh bodies 4 are respectively installed on the upper surfaces of the thigh placement device 2 and the calf placement device 3 via hooks 206 and buckles 403. The device size is adjusted according to the patient's needs. Through the control console, multiple second electric telescopic rods 204 and multiple third electric telescopic rods 304 drive two first support frames 205 and two second support frames 305 to move linearly to both sides. When the size is suitable, the control console stops the extension and retraction of the second and third electric telescopic rods 204 and 304. Then, the device is started through the control console, and the first electric telescopic rod 102 drives the traction rod 103 to reciprocate linearly.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
