The present invention relates to a shoulder rehabilitation treatment apparatus, and more particularly, to a shoulder rehabilitation treatment apparatus that enables a rehabilitation exercise while lifting an arm using an actuator, so that a user can easily proceed with the rehabilitation exercise without external assistance. About.

As the elderly and sports active population increase, interest in rotator cuff injury of the shoulder joint has increased significantly, and the development of diagnostic methods and devices has made it easier to diagnose such injuries. In addition, arthroscopy can easily determine the size of the rupture, and treatments such as restoration and reconstruction have reported good results.

On the other hand, rehabilitation exercises are very important because the joints are not immediately recovered even after surgery, but the range of motion and the speed of recovery are changed according to the subsequent recovery treatment. However, since a lot of pain is involved in joint rehabilitation exercise, it is difficult to exercise by the patient himself, and eventually, limitation of motion range (LOM) appears due to contracture and inflammation. To prevent this, joint motion range exercise is performed, and the most common joint motion is the continuous passive motion (CPM).

CPM is an exercise performed by pure external force such as a therapist or mechanical device, and provides continuous passive movement to patients with joint stiffness or surgery to restore the function of the joint. Because CPM is a passive exercise by a mechanical device rather than a patient's own movement, it helps to recover the range of motion (ROM) without causing muscle fatigue, and helps to reduce pain and prevent complications.

Since these CPM devices are expensive to rent and exist in most hospitals, patients who are far from the hospital must invest a large amount of time to use them. In addition, when the alignment with the shoulder rotation axis is not perfectly aligned, it may cause great inconvenience. Above all, even with perfect alignment, there is a problem that the patient feels uncomfortable because consideration for the movement of the shoulder rotation axis is omitted.

It is a diagram schematically showing an actuator in an unfolded state.

1 to 4, the actuator 300 is to lift the arm upward using the pressure of air, one side is mounted on the arm mounting portion 100, the other side is the mounting guide of the body mounting portion 200 ( 210) and configured to be bent in a zigzag shape. The actuator 300 is formed by connecting a plurality of empty air bags to be bent in a zigzag shape so that air is introduced. In more detail, the plurality of air bags include a first coupling bag 310 mounted on the arm mounting part 100 and the outer surface of the body mounting part 200 facing the arm mounting part 100 when the arm mounting part 100 is lowered. It includes a second coupling bag 320 mounted on one side and a plurality of connection bags 330 disposed between the first coupling bag 310 and the second coupling bag 320. The connection bag 330 has a first connection bag 332 connected to be bent in a direction opposite to the user's armpit to one side of the first combination bag 310 positioned to face the user's armpit, and one side is a first combination The second connection is connected to be bent to one side of the first connection bag 332 that is not connected to the pocket 310, and the other side is connected to be bent to one side of the second combination bag 320 positioned to face the user's armpit. Includes a pocket 334. In addition, the first coupling bag 310, the first coupling bag 332, the second coupling bag 334, and the second coupling bag 320 are formed to be bent in a zigzag shape while being integrally connected to each other. And the inside of the first bonding bag 310, the first connecting bag 332, the second connecting bag 334, and the second bonding bag 320 are also integrally connected, and from the outside to the second bonding bag 320. The incoming air is sequentially introduced into the second connecting bag 334, the first connecting bag 332, and the first connecting bag 310.

And when air flows into the actuator 300 from the outside, the inside of the second coupling bag 320, the second coupling bag 334, the first coupling bag 332, and the first coupling bag 310 expands and the jig The actuator 300 folded into a shape is unfolded, which lifts the arm mounting portion 100 upward. Conversely, when the air introduced into the actuator 300 flows out, the inside of the second coupling pocket 320, the second coupling pocket 334, the first coupling pocket 332, and the first coupling pocket 310 contracts and the actuator The 300 is folded in a zigzag shape, which lowers the arm mounting portion 100 downward.

As described above, the present invention can be used as an orthosis that can support the arm using the support 220 of the body mounting part 200 in normal times, and when rehabilitation is required, the rehabilitation exercise while lifting the arm using the actuator 300 By making this possible, there is an effect that the user can easily proceed with the rehabilitation exercise without external help.

Referring to FIG. 5, a pair of air bags facing each other among a plurality of air bags, for example, the first and second connecting

bags

332 and 334 are a support member 340, a central cover 342, and an air pocket. (344) and an outer cover (346). The support member 340 is a first support plate 340a serving as a skeleton for the first connection bag 332, and a second support plate 340a positioned on one side of the first support plate 340a to serve as a skeleton for the second connection bag 334. The support plate 340b and the first support plate 340a and the second support plate 340b are hingedly coupled to each other so that the first support plate 340a and the second support plate 340b are rotated in a bent state. . The first and

second support plates

340a and 340b are formed as thin and non-bending plates, and may be formed of, for example, carbon fiber reinforced plastics (CFRP) material. The central cover 342 is formed to integrally cover one surface of the support member 340. The air pocket 344 is positioned to cover one surface of the central cover 342, and is formed to allow air to be introduced therein. The outer cover 346 integrally covers the support member 340 and the air pocket 344, and is formed of a fabric material that does not stretch, for example, a ripstop material, so that the air pocket 344 is larger than a certain size. It is controlled so that it does not expand.

In this way, the actuator 300 has a second support plate (340a, 340b) therein and a hinge portion (340c) for hinge-joining them, so that the actuator 300 does not swing from side to side and rotates in the vertical direction while stably holding the arm. There is an effect that can be lifted.

Referring to Figure 6 (a), in general, the upper and lower motion of the arm moves not only the humerus of the arm, but also the scapula to which the humerus is connected, and this is referred to as scapular brachial rhythm. Because of this scapular upper arm rhythm, the shoulder shaft itself moves and the arm behaves as if it stretches in the process of lifting the arm, so the rotation shaft should not be fixed.

In the present invention, in order to solve this problem, the actuator 300 is formed in a zigzag shape so that the length of the actuator 300 is variable. That is, if the first shoulder rotation axis is defined as the initial rotation axis P1 while the arm is lowered, the actuator 300 expands while the arm is relaxed in a comfortable state as shown in FIG. 6B. When is raised to the top by about 90 degrees, the current shoulder's rotation axis P2 rises more than the initial rotation axis P1. In this state, as shown in (c) of FIG. 6, when the actuator 300 expands and raises the shoulder more to the top by about 180 degrees, the current shoulder's rotation axis P2 rises slightly higher than the initial rotation axis P1. do.

In this way, since the actuator 300 expands and increases its overall length, and contracts and decreases its overall length, the length of the actuator 300 sufficiently increases or decreases according to the change of the rotation axis of the arm, so that the actuator 300 is at an accurate angle. It has the effect of lifting the user's arm up to 180 degrees.

Referring to FIG. 7, since the actuator 300 is mounted on one side of the body mounting part 200, when the upper side of the actuator 300 lifts the arm while the actuator 300 is unfolded, the lower side of the actuator 300 is While being supported on one side of the mounting part 200, pressure is applied to one side of the body mounting part 200 to the rear. At this time, since one side of the body mounting part 200 on which the actuator 300 is mounted is formed of a material stronger than the other side of the body mounting part 200, one side of the body mounting part 200 is resistant to the torsion force caused by the actuator 300. It has the effect of making it possible.

In addition, one side of the body mounting part 200 on which the actuator 300 is mounted is formed to be concave inward than the other side of the body mounting part 200, so that the upper arm of the user is supported by the support part 220, the body mounting part 200 ) Is configured to provide a space in which the actuator 300 is accommodated.

Referring to FIG. 8, the angle adjusting member adjusts the opening angle between a pair of air bags that are connected to be bent to each other among a plurality of air bags, for example, a first coupling bag 310 and a first connection bag It includes a first angle adjusting member 400 provided between the (332) and a second angle adjusting member 402 provided between the second coupling bag 334 and the second coupling bag 320. Since the first angle adjusting member 400 and the second angle adjusting member 402 have the same structure, the first angle adjusting member 400 will be mainly described below.

The first angle adjustment member 400 includes a motor 410 mounted at an end of the first coupling bag 310, and one end is wound around the motor 410 and the other end is connected to the end of the first connection bag 332. Includes a wire 420. In addition, a wire fixing part 422 is mounted to the end of the first connection bag 332 so that the wire 420 is fixed.

And when the actuator 300 is unfolded, as the wire 420 is wound or unwound from the motor 410 by the rotation of the motor 410, the first coupling bag 310 and the first connection bag 332 are unfolded. The angle is controlled.

As the motor 410 rotates when the actuator 300 is unfolded, the unfolding angle of the first coupling pocket 310 and the first coupling pocket 332 is accurately controlled, so that the unfolding angle of the actuator 300 is more than necessary. Since it can be controlled so as not to be unfolded, there is an effect that the unfolding angle of the actuator 300 can be set with an accurate protocol according to the user's surgical site and the operation state.

1 to 9, the control module 500 includes an input unit 510, a communication unit 520, an air injection drive unit 530, a motor drive unit 540, and a control unit 550.

The input unit 510 is composed of switches, buttons, etc., and is configured to input various signals to the control unit 550, and may be omitted in some cases. The communication unit 520 is connected to an external terminal (not shown) through wireless communication to input various signals to the control unit 550. The external terminal may be composed of a smartphone of a user or a person concerned, and the wireless communication may be composed of short-range wireless communication such as Bluetooth, and a related program may be installed on the smartphone.

The air injection drive unit 530 receives a control signal from the control unit 550 and controls the compressor C to inject air so that the compressor C can inject or remove air. The compressor (C) is connected to the actuator (300) is a conventional configuration capable of introducing or outflowing air to the actuator (300). The motor driving unit 540 receives a control signal from the controller 550 to rotate the motor 410 forward or reverse.

The controller 550 controls the actuator 300 to expand or contract by controlling the air injection drive unit 530 when an air injection signal is received so that the compressor C injects air through the input unit 510 or the communication unit 520 do. When the actuator 300 is expanded, the overall length of the actuator 300 becomes longer, so that the actuator 300 lifts the arm upward. When the actuator 300 is contracted, the entire length of the actuator 300 is shortened, so that the actuator 300 lowers the arm downward.

In this case, the control unit 550 may rotate the motor 410 by receiving the opening angle of the actuator 300 through the input unit 510 or the communication unit 520. Alternatively, the controller 550 may control the rotation of the motor 410 according to the amount of air introduced into the actuator 300. As the motor 410 is rotated, the unfolding angle of the actuator 300 is accurately controlled, so that the unfolding angle of the actuator 300 is not unfolded more than necessary.

In this way, the user expands or contracts the actuator 300 in a manner of executing a program entered in advance on the smartphone, and rotates the motor 410 to control the unfolding angle of the actuator 300. Even so, it has the effect of accurately and safely performing rehabilitation exercises.
