Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical rehabilitation equipment, and in particular to an intelligent external fixation brace system for limb function rehabilitation. Background Art
[0002] Patients with lower limb fractures lack exercise for a long time in their legs. During the recovery stage, they are often unable to maintain a standing or bending posture for a long time due to lack of leg muscle strength. Existing braces for lower limb rehabilitation can generally only fix the limbs and cannot guide patients to perform targeted strength training on their legs. The lower limbs are not active enough and the flexibility of the lower limb joints is poor, which will affect the rapid recovery of the patients' legs. Utility Model Content
[0003] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an intelligent external fixation brace system for limb function rehabilitation.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] The invention discloses an intelligent external fixation brace system for limb function rehabilitation, comprising a thigh collar and a calf collar, both of which have semicircular contours, symmetrically fixed mounting plates are arranged on both sides of the thigh collar, a turntable and a rotating plate are rotatably connected to the mounting plate on one side, an integrally formed extension plate is arranged outwardly on the edge of the turntable, a movable arm is slidably connected to the disk surface of the rotating plate, the extension plate and the opposite ends of the movable arm are maintained in transmission connection through a rotating shaft, the ends of the movable arms on both sides away from their respective extension plates are fixedly mounted on both sides of the calf collar respectively, and the inner surfaces of the calf collars are provided with massage bumps.
[0006] In a preferred technical solution, a plurality of nylon tightening belts are arranged on the rear side of the thigh sleeve.
[0007] In a preferred technical solution, a dual-axis motor is arranged between the mounting plates on both sides, and the driving shafts extending outward from the output ends on both sides of the dual-axis motor are respectively connected to the rotating disks on the two mounting plates to maintain a coaxial rotation.
[0008] In a preferred technical solution, a fixed block that rotates coaxially is arranged on the disk surface of the rotating disk, a guide groove is formed on the fixed block, and the arm rod of the movable arm is built into the guide groove and slides along the guide groove.
[0009] In a preferred technical solution, the mounting plate is a square plate, and the turntable and the rotating plate are respectively arranged at two opposite corners of the mounting plate.
[0010] In a preferred technical solution, the thigh collar and the calf collar do not contact each other, and the notch on the thigh collar faces backwards, while the notch on the calf collar faces forwards.
[0011] The beneficial effects of the utility model are:
[0012] The lower limb rehabilitation support assembly proposed in this scheme solves the problem that the existing lower limb rehabilitation braces cannot guide patients to perform leg strength training, resulting in slow recovery of patients' lower limbs. By driving the motor, the swinging extension plate drives the calf collar to guide the patient to bend back and forth autonomously within a range of nearly 90°, thereby performing strength recovery exercises for the lower limbs and strengthening joint activities, thereby prompting the patient's lower limbs to quickly regain lost functions and accelerating the recovery of the patient's lower limbs.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] In this embodiment, refer to Figure 1-5 An intelligent external fixation brace system for limb function rehabilitation comprises a thigh collar 1 and a calf collar 2, both of which have semicircular contours and do not contact each other. Figure 1 Or attach Figure 2It can be seen that the notch on the thigh sleeve 1 faces backwards, and the notch on the calf sleeve 2 faces forwards. Here, a plurality of nylon tightening belts 3 are arranged on the rear side of the thigh sleeve 1. The tightening belts 3 are used to fix the patient's thigh, ensuring that the thigh sleeve 1 can just cover the patient's thigh, and the patient's calf is against the calf sleeve 2, and the calf sleeve 2 is in an active state, which is convenient for subsequent bending exercises.
[0021] The thigh collar 1 is provided with symmetrically fixed mounting plates 4 on both sides, and a rotating disk 5 and a rotating disk 7 are rotatably connected to the mounting plate 4 on one side, and an integrally formed extension plate 6 is provided outwardly on the edge of the rotating disk 5. Figure 1 Or attach Figure 2 It can be seen that the mounting plate 4 is a square plate, and the turntable 5 and the rotating disk 7 are respectively arranged at two opposite corners of the mounting plate 4. Here, the limit position of the extension plate 6 is horizontal or vertical, and the position of the extension plate 6 is horizontal or vertical, which is just in the same straight line with the rotating disk 7. Therefore, the extension plate 6 is controlled by the rotation of the turntable 5, and the angle of its back and forth rotation can be regarded as 90°.
[0022] As attached Figure 3 As shown, a dual-axis motor 9 is arranged between the mounting plates 4 on both sides, and the driving shafts extending outward from the output ends on both sides of the dual-axis motor 9 are respectively connected to the turntables 5 on the two mounting plates 4 to maintain a coaxial rotation. The dual-axis motor 9 is used to drive the turntables 5 on both sides to maintain the same rotation direction and rotation angle, so that the two sides maintain consistency of movement.
[0023] A movable arm 8 is slidably connected to the surface of the rotating disk 7. Figure 5 As shown, a fixed block 11 that rotates coaxially is arranged on the disk surface of the rotating disk 7, and a guide groove 12 is opened on the fixed block 11. The arm rod of the movable arm 8 is built into the guide groove 12 and slides along the guide groove 12.
[0024] The extension plate 6 and the opposite ends of the movable arm 8 are connected in a transmission connection via a rotating shaft. Since the extension plate 6 rotates back and forth at an angle of approximately 90 degrees, the movable arm 8 connected in a transmission connection with the extension plate 6 can also be regarded as turning back and forth at an angle of 90 degrees. The ends of the movable arms 8 on both sides away from the respective extension plates 6 are fixedly mounted on both sides of the calf collar 2, and the two swingable movable arms 8 are used to control the calf collar 2 to turn back and forth within a range of 90 degrees.
[0025] Finally, it should be added that the inner surface of the calf ring 2 is provided with massage bumps 10 .
[0026] When using the present rehabilitation brace, the patient puts his thigh into the thigh sleeve 1 and tightens it with the tightening belt 3. Then, the dual-axis motor 9 is started. The dual-axis motor 9 can drive and control the movable arm 8 and the calf sleeve 2 to flip back and forth. When the patient's legs are stretched or bent autonomously, the patient can use the auxiliary force of the movable arm 8 to complete the action. It should be made clear that the power of the dual-axis motor 9 is adjustable to control the rotation speed of the turntable 5. As the patient's lower limb strength gradually recovers, the power of the dual-axis motor 9 can be gradually increased to achieve the purpose of quickly bending or straightening the calf. This can strengthen the training of the patient's joints, improve joint flexibility, and enable the patient's lower limbs to quickly recover health.
[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
