Description

Technical Field

[0001] This application relates to the field of rehabilitation medical device technology, and more specifically, to a shoulder joint lateral external rotation assist device. Background Technology

[0002] After shoulder joint injury or adhesions, lateral external rotation is a crucial training component in the rehabilitation process. However, when the patient's range of motion for lateral external rotation is significantly limited or stiffness occurs, compensatory movements often arise during this exercise. Specifically, this manifests in two ways: first, the elbow gradually moves away from the body during shoulder external rotation; second, the elbow gradually straightens during shoulder external rotation. Both of these situations weaken the effectiveness of lateral external rotation training. To ensure the effectiveness of the training, assistance from others is usually required to avoid compensatory movements. However, this approach has the following drawbacks: firstly, if training cannot be conducted in a hospital, family members may not be able to precisely control the strength of the assistance or ensure the correctness of the movements; secondly, for patients living alone, the lack of family assistance makes it difficult for them to control the direction and accuracy of their training. Utility Model Content

[0003] The purpose of this application is to provide a shoulder joint lateral external rotation assist device that can reduce compensatory effects during patient training and improve patient training efficiency.

[0004] To achieve the above objectives, embodiments of this application provide a shoulder joint lateral external rotation assist device, comprising: a first fixation member, a second fixation member, and a third fixation member. The first fixation member is fixedly disposed; the second fixation member is disposed on the patient's upper arm and connected to the first fixation member, the first fixation member restricting the second fixation member from moving away from it, and the second fixation member being able to rotate relative to the first fixation member; the third fixation member is disposed on the patient's forearm and is perpendicular to the second fixation member, so that the patient's forearm remains perpendicular to the upper arm, and the third fixation member rotates about the axis of the second fixation member, allowing the patient's forearm to rotate with the axis of the upper arm as the center of rotation.

[0005] In one embodiment, the shoulder joint lateral external rotation assist device further includes a transmission rod, one end of which is connected to the third fixing member, and the transmission rod pushes the third fixing member to rotate about the axis of the second fixing member.

[0006] In one embodiment, the transmission rod is detachably connected to the third fixing member.

[0007] In one embodiment, the second fastener and the third fastener are connected by an L-shaped plate.

[0008] In one embodiment, the first fixation member includes a fixing part and a connecting part. The fixing part is fixedly disposed on the patient's torso, and the connecting part is disposed on the side of the fixing part near the second fixation member, and the connecting part is connected to the second fixation member.

[0009] In one embodiment, two or more fixing parts are spaced apart, and adjacent fixing parts are connected by a fixing plate.

[0010] In one embodiment, the second fastener includes at least two first mounting portions fixedly disposed on the patient's upper arm, with the at least two first mounting portions spaced apart.

[0011] In one embodiment, adjacent first mounting portions are connected by a first telescopic member, the length of which is extendable to make the distance between adjacent first mounting portions adjustable.

[0012] In one embodiment, the third fixation member includes at least two second mounting portions fixedly disposed on the patient's forearm, with the at least two second mounting portions spaced apart.

[0013] In one embodiment, adjacent second mounting portions are connected by a second telescopic member, the length of which is extendable to make the distance between adjacent second mounting portions adjustable.

[0014] In this application, the connection between the first and second fixation members prevents the patient's upper arm from moving away from the torso. The second and third fixation members are set vertically to prevent the elbow from gradually straightening when the shoulder is externally rotated, thereby improving the patient's rehabilitation training effect.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] Embodiments of this application provide a shoulder joint lateral external rotation assist device, including a first fixation member 100, a second fixation member 200, and a third fixation member 300.

[0032] The first fastener 100 is fixedly installed, and the first fastener 100 provides an installation base for the second fastener 200.

[0033] For example, the first fastener 100 is fixed to the torso 510 of the patient 500.

[0034] Clinically, the trunk 510 mainly includes the chest, abdomen, back, pelvis and perineum, while the head and limbs are not included. The patient's arm 500 includes the forearm 520, upper arm 530 and hand. The upper arm 530 is close to the shoulder, and the forearm 520 is located between the upper arm 530 and the hand.

[0035] In another embodiment, the first fastener 100 is fixed to the hospital bed or other fixed table surface.

[0036] like Figure 4 As shown, the second fastener 200 is disposed on the upper arm 530 of the patient 500. Exemplarily, the second fastener 200 is fixedly connected to the patient's arm 500.

[0037] like Figure 4 and Figure 5 As shown, the second fixing member 200 is connected to the first fixing member 100. The first fixing member 100 restricts the second fixing member 200 from moving away from it, and the second fixing member 200 is rotatable relative to the first fixing member 100. Exemplarily, the connection between the second fixing member 200 and the first fixing member 100 can be, for example, by binding or hinge, fixing the positions of the second fixing member 200 and the first fixing member 100, but allowing the second fixing member 200 to rotate relative to the first fixing member 100.

[0038] like Figure 5 As shown, the third fixation element 300 is installed on the patient's forearm 520, and as... Figure 1 As shown, the third fixation member 300 is set perpendicular to the second fixation member 200 so that the patient's forearm 520 and upper arm 530 remain perpendicular.

[0039] The third fixing member 300 rotates around the axis of the second fixing member 200, so that the patient's forearm 520 can rotate with the axis of the upper arm 530 as the center of rotation.

[0040] like Figure 4 and Figure 5 As shown, the left forearm 520 of patient 500 rotates around the axis of the left upper arm 530. During this process, the left upper arm 530 of patient 500 drives the second fixing member 200 to rotate, and the left forearm 520 of patient 500 drives the third fixing member 300 to rotate. At the same time, the first fixing member 100 restricts the displacement of the second fixing member 200 away from the first fixing member 100. The forearm 520 of patient 500... Figure 4 State transition to Figure 5 As shown, patient 500's forearm 520 underwent external rotation.

[0041] In this application, the connection between the first fixation member 100 and the second fixation member 200 prevents the patient's upper arm 530 from moving away from the torso 510. The second fixation member 200 and the third fixation member 300 are set vertically, which has the advantage that the elbow will gradually straighten when the shoulder externally rotates, thus improving the rehabilitation training effect of the patient 500.

[0042] like Figure 1 and Figure 2 As shown, in one embodiment, the shoulder joint lateral external rotation assist device further includes a transmission rod 410, one end of which is connected to a third fixing member 300. The transmission rod 410 pushes the third fixing member 300 to rotate axially around the second fixing member 200.

[0043] The transmission rod 410 may be a solid rod structure or a hollow rod structure.

[0044] The connection between the transmission rod 410 and the third fixed member 300 can be, for example, a hinged or sliding connection.

[0045] For example, the driving force of the transmission rod 410 can be mechanical power, or it can be... Figure 4 and Figure 5 The artificial driving force shown is, for example, the patient 500 pushing the transmission rod 410 with the other hand, which causes the third fixing member 300 and the patient 500's forearm 520 to rotate outward.

[0046] In this application, one end of the transmission rod 410 is connected to the third fixing member 300, which can be driven to rotate axially around the second fixing member 200, thereby enhancing the rotational function of the assistive device. This allows the patient 500 to more smoothly and accurately simulate natural movements when performing shoulder joint lateral external rotation exercises, improving the effectiveness of rehabilitation training.

[0047] In this application, the transmission rod 410 is designed so that the patient 500 can actively train by pushing the transmission rod 410 using their own strength. This active training method helps to enhance the patient 500's muscle strength and joint stability, while reducing reliance on auxiliary training personnel and lowering rehabilitation costs.

[0048] In one embodiment, the transmission rod 410 and the third fixing member 300 are detachably connected. Exemplarily, the transmission rod 410 is provided with a connecting pin, and the third fixing member 300 is provided with a pin sleeve that mates with the connecting pin. The connecting pin connects with the pin sleeve, causing the transmission rod 410 and the third fixing member 300 to be hinged. Pulling the connecting pin out of the pin sleeve disengages the transmission rod 410 from the third fixing member 300. In another embodiment, the detachable connection between the transmission rod 410 and the third fixing member 300 takes other forms. For example, the transmission rod 410 is provided with a pin sleeve, and the third fixing member 300 is provided with a connecting pin that mates with the pin sleeve. The connecting pin connects with the pin sleeve, causing the transmission rod 410 and the third fixing member 300 to be hinged. Pulling the connecting pin out of the pin sleeve disengages the transmission rod 410 from the third fixing member 300.

[0049] In this application, the transmission rod 410 is detachably connected to the third fixing member 300 to meet the needs of the patient 500 at different stages of rehabilitation. For example, in the early stage of rehabilitation, the patient 500 needs the transmission rod 410 to assist in external rotation training of the forearm 520, so the transmission rod 410 is installed on the third fixing member 300; in the middle and late stages of rehabilitation, the patient 500 can rely on the strength of the affected forearm 520 itself to carry out rehabilitation training, at which time the transmission rod 410 will be removed.

[0050] like Figure 1 As shown, in one embodiment, the second fastener 200 and the third fastener 300 are connected by an L-shaped plate 420 so that the second fastener 200 and the third fastener 300 are arranged vertically.

[0051] For example, the L-shaped plate 420 has a first plate body and a second plate body. The first plate body and the second plate body are vertically fixed by means of welding, snap-fitting, riveting, bolting or integral molding. The first plate body and the second fixing member 200 are fixed by means of welding, snap-fitting, riveting, bolting or integral molding. The second plate body and the third fixing member 300 are fixed by means of welding, snap-fitting, riveting, bolting or integral molding, thereby keeping the patient's forearm 520 and upper arm 530 vertical, preventing the patient's elbow joint from straightening during training, and improving the efficiency of rehabilitation training.

[0052] like Figure 3As shown, in one embodiment, the first fastener 100 includes a fixing portion 110 and a connecting portion 120, with the fixing portion 110 fixedly disposed on the torso 510 of the patient 500. Exemplarily, the fixing portion 110 is a strap or similar material, which is fixed to the torso 510 of the patient 500. In another embodiment, the fixing portion 110 is a flexible sleeve supported by a retractable material, which is fitted onto the torso 510 of the patient 500; the flexible material is, for example, rubber or silicone.

[0053] like Figure 4 As shown, the connecting part 120 is provided on the side of the fixing part 110 near the second fixing member 200, and the connecting part 120 is connected to the second fixing member 200.

[0054] The connecting part 120 may be, for example, a connecting hole, a connecting buckle, or a connecting ring. When the connecting part 120 is a connecting hole, the second fastener 200 is secured by passing a rope or the like through the connecting hole.

[0055] In this application, the connecting portion 120 provides a mounting base for the third fixation member 300. By stably fixing the first fixation member 100 to the patient 500's torso 510 and connecting it to the second fixation member 200 via the connecting portion 120, this mechanical structure provides stable support and traction for the patient 500. This design helps the patient 500 maintain correct posture and movement trajectory during training, thereby improving training effectiveness and reducing the risk of injury.

[0056] like Figure 3 As shown, in one embodiment, two or more fixing parts 110 are provided at intervals, and adjacent fixing parts 110 are connected by fixing plates 130.

[0057] For example, the connecting portion 120 is disposed on the fixing plate 130. However, in another embodiment, the connecting portion 120 is disposed on the fixing portion 110.

[0058] For example, the fixing part 110 and the fixing plate 130 are fixedly connected by means of adhesive, bolt connection, snap-fit ​​or anchor connection.

[0059] For example, two fixing portions 110 are spaced apart. In another embodiment, three fixing portions 110 are spaced apart. In yet another embodiment, four fixing portions 110 are spaced apart.

[0060] In this application, the fixation parts 110 are spaced apart and connected by the fixation plate 130, which effectively reduces the direct contact area between the first fixation member 100 and the patient's torso 510. This design avoids excessive pressure on the patient's torso 510 caused by prolonged and large-area contact, reduces discomfort, and improves the patient's comfort during rehabilitation training.

[0061] In this application, although the fixing parts 110 are spaced apart, the overall structural stability and support are maintained through the connection of the fixing plates 130. This design reduces weight while ensuring the reliability and safety of the mechanical structure during rehabilitation training.

[0062] like Figure 1 As shown, in one embodiment, the second fastener 200 includes at least two first mounting portions 210, which are fixedly mounted on the upper arm 530 of the patient 500, and the at least two first mounting portions 210 are spaced apart.

[0063] For example, the first mounting part 210 is a component having a plate and a strap that can be fixed to the upper arm 530 of the patient 500. The strap is fixedly connected to the plate, and the plate is fixed to the upper arm 530 of the patient 500 by the strap.

[0064] In this application, at least two first mounting portions 210 are spaced apart to help distribute the pressure of the fixation on the patient's upper arm 530. This design can reduce pain and discomfort caused by excessive pressure at a single point, and improve the patient's comfort during training or rehabilitation.

[0065] like Figure 1 and Figure 2 As shown, in one embodiment, adjacent first mounting portions 210 are connected by a first telescopic member 220. The length of the first telescopic member 220 can be extended or retracted so that the distance between adjacent first mounting portions 210 is adjustable, thereby allowing the second fixing member 200 to adapt to patients 500 of different body types and improving adaptability.

[0066] For example, the first telescopic member 220 is installed on the plate of the first mounting part 210, and the installation method is, for example, adhesive, bolt connection, snap-fit ​​or anchor connection.

[0067] For example, the first telescopic member 220 is, for example, a screw mechanism or a rack and pinion mechanism.

[0068] like Figure 1 As shown, in this embodiment, a first locking switch 230 is provided on the first mounting part 210. The first locking switch 230 is used to lock the length of the first telescopic member 220 or to unlock the first telescopic member 220. The first locking switch 230 is, for example, a locking pin, which can be engaged in the bolt screw mechanism or gear rack mechanism of the first telescopic member 220 to lock the first telescopic member 220.

[0069] like Figure 1As shown, in one embodiment, the third fastener 300 includes at least two second mounting portions 310, which are fixedly mounted on the forearm 520 of the patient 500, and the at least two second mounting portions 310 are spaced apart.

[0070] For example, two second mounting portions 310 are spaced apart; in another embodiment, three second mounting portions 310 are spaced apart; in yet another embodiment, four or five second mounting portions 310 are spaced apart, etc.

[0071] For example, the second mounting part 310 has a plate and a strap. The plate is fixed to the forearm 520 of the patient 500 by the strap.

[0072] In this application, the second mounting part 310 is spaced out to reduce pressure on the patient's forearm 520 and improve comfort.

[0073] like Figure 1 As shown, in one embodiment, adjacent second mounting portions 310 are connected by a second telescopic member 320, the length of which is telescopic, so that the distance between adjacent second mounting portions 310 is adjustable.

[0074] For example, the second telescopic member 320 is installed on the plate of the second mounting part 310, and the installation method is, for example, adhesive, bolt connection, snap-fit ​​or anchor connection.

[0075] For example, the second telescopic member 320 is, for example, a screw mechanism or a rack and pinion mechanism.

[0076] like Figure 1 As shown, in this embodiment, a second locking switch 330 is provided on the second mounting part 310. The second locking switch 330 is used to lock the length of the second telescopic member 320 or to unlock the second telescopic member 320. The second locking switch 330 is, for example, a locking pin, which can be engaged in the bolt screw mechanism or gear rack mechanism of the second telescopic member 320 to lock the second telescopic member 320.

[0077] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0078] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
