Description

Technical Field

[0001] This utility model relates to the field of medical rehabilitation equipment technology, and in particular to a shoulder joint abduction and external rotation brace. Background Technology

[0002] Shoulder dislocation is a common type of joint dislocation in emergency surgery. Due to its unique physiological characteristics and anatomical structure, the shoulder joint is highly susceptible to trauma, and is prone to dislocation, rotator cuff injury, and proximal humeral fracture. In clinical treatment, abduction braces are generally used for rehabilitation. Abduction braces can prevent secondary impact after shoulder dislocation, reduce tension during rotator cuff repair, and distribute pressure on the proximal humeral fracture ends to prevent displacement. They can also be used for fixation after shoulder replacement surgery, thereby effectively maintaining the stability of the shoulder joint and promoting healing.

[0003] However, traditional abduction braces mostly use internal rotation fixation to restrict shoulder joint movement. Existing clinical research has explored fixation methods after shoulder joint rotational reduction in depth. For example, in the article "Comparative Study of the Efficacy of Different Fixation Methods after Emergency Rotational Reduction of Shoulder Dislocation" (Kong Xiangren et al., 2021), a controlled trial found that the redislocation rate of patients in the observation group with external rotation fixation (7.5%) was significantly lower than that in the traditional internal rotation fixation group (32.5%). This study result indicates that considering maintaining an appropriate external rotation angle of the shoulder joint in the design of abduction braces can effectively reduce the risk of shoulder joint redislocation.

[0004] In addition, existing abduction braces mainly rely on the patient's own trunk support, which is suitable for the patient's fixation needs when walking upright. However, when the patient changes from a standing position to a lying position, the abduction brace cannot maintain the original internal rotation angle with the change of body position. It is necessary to use a pillow or hard object to elevate the affected shoulder. Otherwise, the shoulder joint will further internally rotate due to gravity, which will increase the tension of the sutured muscle groups and aggravate the patient's pain.

[0005] Therefore, there is a need for an abduction brace that can ensure the shoulder joint is in the ideal external rotation angle regardless of the patient's different body positions. Utility Model Content

[0006] The technical problem to be solved by this utility model is:

[0007] Existing abduction braces restrict shoulder joint movement through internal rotation fixation and cannot maintain the rotation angle when the patient's position changes.

[0008] To solve the above-mentioned technical problems, this utility model provides a shoulder joint abduction and external rotation brace, including a brace body, one side of the brace body is used to fit close to the user, the upper part of the rear end face of the brace body is a first arc surface with an upward convexity of radius R1, and the upper part of the front end face of the brace body is a second arc surface with an upward convexity of radius R2.

[0009] R2 is greater than R1, and the upper surface of the support body is a smooth, continuous arc surface connecting the front and rear ends of the support body.

[0010] The side of the brace away from the user is also connected to a support platform. The rear end of the support platform is flush with the rear end of the brace body, and the front end of the support platform is flush with the front end of the brace body. The support platform extends from the rear end to the front end and towards the side away from the brace body. The upper surface of the support platform is the support surface, and the upper part of the support surface forms a support space for supporting the forearm.

[0019] Preferably, the support body is also provided with a grip ball on the side wall at the front end of the support platform.

[0020] Preferably, the main body of the brace is integrally connected with straps.

[0021] Compared with the prior art, the beneficial effects of this embodiment of the shoulder joint abduction and external rotation brace are as follows:

[0022] A shoulder brace includes a brace body, one side of which is close to the user. The upper part of the rear end face of the brace body is a first arc surface with an upward convexity of radius R1, and the upper part of the front end face of the brace body is a second arc surface with an upward convexity of radius R2; R2 is greater than R1. The upper surface of the brace body is a continuous arc surface that smoothly connects the front and rear ends of the brace body. A support platform is also connected to the side of the brace body away from the user. The rear end of the support platform is flush with the rear end of the brace body, and the front end of the support platform is flush with the front end of the brace body. The support platform extends from the rear end to the front end and towards the side away from the brace body. The upper surface of the support platform is a support surface, and the upper part of the support surface forms a support space for supporting the forearm.

[0023] R2 being greater than R1 creates a continuous arc surface that gradually slopes upward from the rear end to the front end, forming a support surface that supports the user's upper arm. The upper part of the support surface forms a support space for the forearm. Under the synchronous action of the support surface and the support platform, the user's upper arm and forearm are kept at the set abduction and external rotation angle, making the sutured tendons of the user more relaxed, which is conducive to healing, helps to improve the treatment effect, and reduces the risk of complications caused by improper posture. In addition, the continuous curved surface of the upper surface also improves the comfort of the user's upper arm in contact with the main body of the brace.

[0024] The rear end of the support platform is also equipped with an upward-extending stop plate. The stop plate at the rear end of the support platform can prevent the external rotation angle from changing when the shoulder joint dislocates backward during changes in posture, thereby increasing the tension of the sutured muscle groups and affecting the treatment effect. It maintains the set rotation angle when the patient's body position changes. Attached Figure Description

[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0032] like Figures 1-5 As shown, a preferred embodiment of the present invention provides a shoulder joint abduction and external rotation brace, comprising a brace body 1, which is integrally molded from a plastic material. The upper part of the rear end face of the brace body 1 is a first arc surface with an upward convexity and a radius of 10 cm (R1), and the upper part of the front end face of the brace body 1 is a second arc surface with an upward convexity and a radius of 15 cm (R2). The upper surface of the brace body 1 is a continuous arc surface that smoothly connects the front and rear ends of the brace body 1. The continuous arc surface forms a support surface that gradually slopes upward from the rear end to the front end. The support surface is used to support the user's upper arm and forms an upper arm sofa, which significantly improves the user's comfort.

[0033] A support platform 2 is connected to the side of the brace body 1 away from the user. The support platform 2 is connected to the brace body 1 through in-mold injection molding. The rear end of the support platform 2 is flush with the rear end of the brace body 1, and the front end of the support platform 2 is flush with the front end of the brace body 1. The distance between the bottom of the rear end of the support platform 2 and the bottom of the brace body 1 is about one-quarter of the height of the rear end face of the brace body 1. The support platform 2 extends from the rear end to the front end and towards the side away from the brace body 1. The upper surface of the support platform 2 is the support surface 3, which forms a forearm sofa, significantly improving the user's comfort. The upper part of the support surface 3 forms a support space for supporting the forearm. When the support surface 3 extends towards the front end, it gradually rises at an angle of 2°. When the support surface 3 extends towards the side away from the brace body 1, it gradually rises at an angle of 45°. This setting allows the support surface 3 to fit well against the forearm and provide good support for the forearm.

[0034] The simultaneous action of the support surface and the support platform ensures that the user's upper arm and forearm are kept at the set abduction and external rotation angle, which helps to improve the treatment effect, reduce the risk of complications caused by improper posture, and the continuous curved surface of the upper surface also improves the comfort of the user's upper arm in contact with the main body of the brace.

[0035] Specifically, the length from the front end face to the rear end face of the support body 1 is 30 centimeters, the height of the front end face of the support body 1 is 20 centimeters, and the height of the rear end face of the support body 1 is 30 centimeters.

[0036] The main body 1 of the brace has an arc-shaped groove 5 with a radius of 7.5 cm on the side closest to the user. The arc-shaped groove 5 matches the contour of the chest wall to improve wearing stability and comfort.

[0037] Specifically, the thickness of the support platform 2 is 3 cm, and the distance between the bottom of the rear end of the support platform 2 and the bottom of the support body 1 is 6.5 cm.

[0038] The rear end of the support platform 2 is also provided with an upwardly extending stop plate 4. The upper end of the stop plate 4 is horizontally set to prevent the shoulder joint from slipping backward and to maintain the external rotation angle of the shoulder joint when the user changes posture.

[0039] The lower part of the end face at the rear end of the main body 1 is a straight segment, and the lower part of the end face at the front end of the main body 1 is also a straight segment. The bottom surface of the main body 1 is a plane to ensure the stability of the support when it is placed. Each side elevation of the main body 1 is a vertical transition surface connecting the upper surface arc surface and the bottom plane. Each vertical transition surface forms a right angle transition with the lower surface plane, which facilitates the casting of the model. The plane at the bottom of the main body 1 forms a stable base, which improves the anti-overturning ability of the shoulder joint support.

[0040] The support body 1 is also provided with a grip ball 6 on the side wall at the front end of the support platform 2. The grip ball 6 is embedded in the side wall at the front end of the support platform 2. The radius of the grip ball 6 is 3 cm. The surface of the grip ball 6 is provided with anti-slip texture for users to grip when performing grip strength training.

[0041] The main body 1 of the brace is integrally connected with a strap 7, and the strap 7 is equipped with an adjustable buckle, so that the tightness of the strap with the shoulder joint can be adjusted.

[0042] In other embodiments, R1 and R2 can also be other combinations of values, as long as R2 is greater than R1.

[0043] In other embodiments, the size of R1 is 8 cm to 12 cm, and the size of R2 is 13 cm to 17 cm.

[0044] In other embodiments, the support surface 3 gradually rises at an angle of 1° to 3° as it extends toward the front end.

[0045] In other embodiments, the support surface 3 gradually rises at an angle of 42° to 48° as it extends toward the side away from the support body 1.

[0046] In other embodiments, the radius of the arcuate groove 5 is 7 to 8 centimeters.

[0047] The working process of this utility model is as follows:

[0048] The operator secures the provided shoulder joint brace to the user using straps 7. The user's upper arm rests on the upper surface of the brace body 1. The upper part of the rear end face of the brace body 1 has an upwardly protruding first arc surface with a radius of R1 and 10 cm, and the upper part of the front end face of the brace body 1 has an upwardly protruding second arc surface with a radius of R2 and 15 cm. The upper surface of the brace body 1 is a smooth, continuous arc surface connecting the front and rear ends of the brace body 1. This continuous arc surface forms a support curve that gradually slopes upward from the rear end to the front end. This support curve supports the user's upper arm, forming an upper arm sofa, significantly improving the user's comfort. The user's forearm rests on the support platform 2 of the brace body 1. The support platform 2 extends from the rear end to the front end and towards the side away from the brace body 1. The upper surface of the support platform 2 is the support surface 3, which forms a forearm sofa, significantly improving the user's comfort. The upper part of the support surface 3 forms a support space for supporting the forearm. When the support surface 3 extends to the front, it gradually rises at an angle of 2°. When the support surface 3 extends to the side away from the main body 1 of the brace, it gradually rises at an angle of 45°. The support surface 3, set in this way, can fit the forearm well and provide good support for the forearm. Under the synchronous action of the support curved surface and the support platform, it ensures that the user's upper arm and forearm are kept at the set abduction and external rotation angle, making the sutured tendons of the user more relaxed, which is conducive to healing, helps to improve the treatment effect, and reduces the risk of complications caused by improper posture. In addition, the setting of the upper surface as a continuous curved surface also improves the comfort of the contact area between the user's upper arm and the main body of the brace.

[0049] The rear end of the support platform 2 is also provided with an upwardly extending stop plate 4. The upper end of the stop plate 4 is horizontally set. When the user changes posture, the stop plate 4 prevents the shoulder joint from slipping backward to maintain the external rotation angle of the shoulder joint.

[0050] The support body 1 is also provided with a grip ball 6 on the side wall at the front end of the support platform 2. The grip ball 6 is embedded in the side wall at the front end of the support platform 2. The radius of the grip ball 6 is 3 cm. The surface of the grip ball 6 is provided with anti-slip texture for users to grip when performing grip strength training.
