Description

Technical Field

[0001] This utility model relates to the field of rehabilitation auxiliary training technology, specifically to an orthopedic postoperative rehabilitation auxiliary training device. Background Technology

[0002] The leg orthopedic postoperative rehabilitation training device is a medical assistive device designed specifically for patients who have undergone leg fractures, joint repair, ligament reconstruction, and other postoperative procedures. It aims to assist patients in carrying out leg function rehabilitation training through scientific mechanical structure and intelligent control technology.

[0003] Postoperative rehabilitation of the leg orthopedics requires step-by-step resistance training to help muscles gradually recover from weak to strong. However, current leg rehabilitation devices, although containing leg-propelling structures, lack flexible resistance adjustment functions. The resistance remains fixed, which can easily cause wound traction pain in the early stages of postoperative rehabilitation due to excessive resistance. In the middle and later stages of rehabilitation, insufficient resistance fails to effectively stimulate muscle groups. The few devices with resistance adjustment are mostly coarse-grained gear switching with low adjustment precision, making it difficult to match the subtle changes in muscle strength that patients experience daily after surgery. Therefore, we propose an auxiliary training device for postoperative rehabilitation of orthopedics. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary training device for postoperative rehabilitation in orthopedics, thereby solving the problems mentioned in the background section. This invention can achieve its purpose through the following technical solution: An orthopedic postoperative rehabilitation training device includes a base plate and a seat located above the base plate. The top surface of the base plate is provided with a sliding mechanism and an adjustment mechanism.

[0005] The sliding mechanism includes a limiting groove formed on the top surface of the base plate, a slider slidably connected in the limiting groove, a cylinder fixedly installed at the top of the slider, and the bottom of the seat fixedly connected to the telescopic end of the cylinder.

[0006] The adjustment mechanism includes two bases fixedly connected to the top surface of the base plate. Each of the two bases has a sliding groove on its top surface, and a sliding plate is slidably connected in both sliding grooves. A fixed plate is fixedly connected to one side of the top surface of the base. Multiple threaded holes are correspondingly opened on the sides of the fixed plate and the sliding plate that are close to each other. An elastic component is detachably connected in each of the axially overlapping threaded holes on the fixed plate and the sliding plate.

[0007] When the fixed plate and the sliding plate approach each other, the elastic component deforms.

[0008] Preferably, the elastic component includes two threaded posts threaded into two threaded holes respectively, and a connecting plate is rotatably connected to the side of the two threaded posts that are close to each other. A spring is fixedly connected to the side of the two connecting plates that are close to each other. A telescopic rod is sleeved on the inner ring of the spring, and the two ends of the telescopic rod are fixedly connected to the wall plates of the two connecting plates respectively.

[0009] Preferably, fixing blocks are fixedly connected to both sides of the fixing plate, and electric telescopic rods are fixedly installed on the side of the two fixing blocks near the sliding plate. Abutment plates are fixedly connected to the telescopic ends of the two electric telescopic rods, and the surfaces of the two abutment plates abut against the side wall of the sliding plate away from the fixing plate.

[0010] Preferably, the sliding plate has two placement slots on the side wall away from the fixed plate.

[0011] Preferably, a rotating motor is fixedly installed on one side of the inner cavity of the limiting groove, and a threaded rod is fixedly connected to the telescopic end of the rotating motor, with the surface of the slider threadedly sleeved on the threaded rod.

[0012] Preferably, all of the elastic components are arranged at equal intervals in both the horizontal and vertical directions.

[0013] The beneficial effects of this utility model are: This invention utilizes a spring, a sliding plate, and a fixed plate. The extension and retraction of the electric telescopic rod causes the abutment plate to move, which in turn pushes the sliding plate to move back and forth. This causes the spring to compress or rebound, thereby changing the resistance of the sliding plate. The resistance adjustment is highly precise. By removing or adding some elastic components to the fixed plate and the sliding plate, the resistance of the sliding plate can also be changed, thus meeting the patient's specified strength training needs and facilitating the matching of subtle daily changes in muscle strength after surgery.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-4 As shown, the orthopedic postoperative rehabilitation auxiliary training device includes: a base plate 1 and a seat 2 located above the base plate 1. A sliding mechanism 3 and an adjustment mechanism 4 are provided on the top surface of the base plate 1. The adjustment mechanism 4 includes two bases 41 fixedly connected to the top surface of the base plate 1. Each base 41 has a groove 42 on its top surface, and a sliding plate 44 is slidably connected within both grooves 42. A fixed plate 43 is fixedly connected to one side of the top surface of each base 41. Multiple threaded holes 45 are correspondingly provided on the sides of the fixed plate 43 and the sliding plate 44 that are close to each other. An elastic component 46 is detachably connected to each axially overlapping threaded hole 45 on the fixed plate 43 and the sliding plate 44. When the fixed plate 43 and the sliding plate 44 approach each other, the elastic component 46 deforms. The elastic component 46 includes components threaded into the two threaded holes 45 respectively. Two threaded posts 461 are rotatably connected to each other on their adjacent sides, and a spring 463 is fixedly connected to each other on their adjacent sides. A telescopic rod 464 is fitted inside the spring 463. The two ends of the telescopic rod 464 are fixedly connected to the wall panels of the two connecting plates 462 respectively. Fixing blocks 47 are fixedly connected to both sides of the fixing plate 43. An electric telescopic rod 48 is fixedly installed on the side of the two fixing blocks 47 near the sliding plate 44. An abutment plate 49 is fixedly connected to the telescopic end of the two electric telescopic rods 48. The surfaces of the two abutment plates 49 abut against the side wall of the sliding plate 44 away from the fixing plate 43. Two placement slots 401 are opened on the side wall of the sliding plate 44 away from the fixing plate 43. Multiple elastic components 46 are arranged in a horizontal and vertical equidistant manner.

[0018] In practice, the electric telescopic rod 48 is activated, and the extension end of the electric telescopic rod 48 retracts to drive the abutment plate 49 to move. The abutment plate 49 pushes the sliding plate 44 to move back and forth, which can drive the spring 463 to compress or rebound, thereby changing the resistance of the sliding plate 44 to meet the patient's specified strength training needs. The resistance of the sliding plate 44 during sliding can also be changed by removing or adding some elastic components 46 to the fixed plate 43 and the sliding plate 44. By squeezing the spring 463 and rotating the threaded column 461, the elastic component 46 can be disassembled from the fixed plate 43 and the sliding plate 44. The detachable nature of the elastic component 46 facilitates its maintenance or repair, making it more convenient to use.

[0019] As a technical optimization of this utility model, the sliding mechanism 3 includes a limiting groove 31 opened on the top surface of the base plate 1, a slider 34 slidably connected in the limiting groove 31, a cylinder 35 fixedly installed at the top of the slider 34, the bottom end of the seat 2 fixedly connected to the telescopic end of the cylinder 35, a rotating motor 32 fixedly installed on one side of the inner cavity of the limiting groove 31, a threaded rod 33 fixedly connected to the telescopic end of the rotating motor 32, and the surface of the slider 34 threadedly sleeved on the threaded rod 33.

[0020] In practice, the patient sits on seat 2, and cylinder 35 is activated. By moving the telescopic end of cylinder 35, the patient can be adjusted to a specified height to use the device for assisted training. The rotating motor 32 is started, and the output end of the rotating motor 32 drives the threaded rod 33 to rotate. The rotation of the threaded rod 33 can drive the slider 34 to slide, thereby adjusting the seat 2 to a specified distance. This allows the user to flex their knees and push the sliding plate 44 to slide for training, thus enhancing the practicality of the device.

[0021] In use, this invention involves removing or adding elastic components 46 to the fixed plate 43 and sliding plate 44, installing a specified number of elastic components 46 on the fixed plate 43 and sliding plate 44, activating the electric telescopic rod 48, and causing the abutment plate 49 to move by retracting the telescopic end of the electric telescopic rod 48. The abutment plate 49 pushes the sliding plate 44 to move, causing the spring 463 to compress, thus adjusting the resistance of the sliding plate 44 to a specified level for use. The patient sits on the seat 2, activates the cylinder 35, and moves the telescopic end of the cylinder 35 to adjust the patient to a specified height for use. Then, the rotating motor 32 is activated, and the output end of the rotating motor 32 drives the threaded rod 33 to rotate. The rotation of the threaded rod 33 causes the slider 34 to slide, adjusting the seat 2 to a specified distance. The patient places their feet in the placement groove 401 and performs leg flexion to push the sliding plate 44 to slide for training.
