Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an auxiliary tool for postoperative rehabilitation of shoulder joint injuries. Background Technology

[0002] Assistive devices for postoperative rehabilitation of shoulder injuries are essential medical devices worn by patients after shoulder injury surgery. They are adjustable limb compression shoulder abduction braces used for postoperative immobilization of the shoulder joint, rehabilitation of rotator cuff injuries, immobilization after reduction of shoulder dislocations, and conservative treatment of proximal humeral fractures. Currently, most assistive devices for postoperative rehabilitation of shoulder injuries suffer from limitations. Traditional braces offer only a single fixation angle and pressure, failing to provide phased and differentiated fixation solutions for different injury types or rehabilitation stages, thus affecting healing efficiency. Existing braces only fix the upper and lower arms with rigid support or simple straps, lacking active compression design. This prevents the use of controllable pressure to promote blood circulation, reduce postoperative swelling, and adjust the compression intensity according to the rehabilitation progress to assist muscle training. Utility Model Content

[0003] Based on the above analysis, the present invention aims to provide an auxiliary tool for postoperative rehabilitation of shoulder joint injuries, in order to solve the problems of fixed angle and single pressure in auxiliary tools for postoperative rehabilitation of shoulder joint injuries.

[0004] The objective of this utility model is mainly achieved through the following technical solutions:

[0005] An assistive tool for postoperative rehabilitation of shoulder joint injuries includes a lumbar support component, an arm support component, and a pressure component;

[0006] The pressurizing component is disposed inside the arm support component, and the pressurizing component is used to apply pressure to the arm;

[0007] The lumbar support assembly includes a lumbar support plate;

[0008] The lumbar support plate has a protruding structure or an outward angle adjustment component on one side. The width of the protruding structure gradually increases from the armpit to the elbow, and the protruding structure is used to abduct the shoulder.

[0009] Furthermore, the outward angle adjustment component includes a rack; the rack is fixed to one side of the waist support plate; the length direction of the rack is the same as the height direction of the waist support plate.

[0010] Furthermore, the rack has graduations along its length.

[0011] Furthermore, the arm support assembly includes a boom support structure, and the boom support structure includes a boom support plate.

[0012] Furthermore, the outward angle adjustment assembly also includes a boom support rod, which is disposed at the lower part of the boom support plate; the end of the boom support rod is hinged to the end of the rack, and the boom support rod can rotate around the hinge axis at the hinge point.

[0013] Furthermore, the outward angle adjustment assembly also includes a connecting rod and a gear. One end of the connecting rod is hinged to the boom support rod, and the other end of the connecting rod is connected to the gear. The gear meshes with the rack and can move along the rack.

[0014] Furthermore, the outward angle adjustment assembly also includes a ratchet and a pawl; the ratchet and the pawl are disposed on both sides of the gear, and the ratchet is coaxial with the gear; the ratchet and the pawl on both sides are used to stop the gear from rotating forward or backward, respectively.

[0015] Furthermore, the pawl is disposed on the gear shaft, and the pawl can move along the axis of the gear shaft; when the pawl is pressed down, the pawl engages between the teeth of the ratchet, and the ratchet stops rotating; when the pawl is moved up, the pawl disengages from the ratchet, and the ratchet starts rotating.

[0016] Furthermore, the arm support assembly also includes a forearm support structure, which includes a forearm support plate.

[0017] Furthermore, the pressurization assembly includes a pressurization airbag, which is disposed inside the upper arm support plate and the lower arm support plate.

[0018] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0019] (1) Compared with the existing shoulder abduction braces which lack pressure-applying components and cannot detect and apply pressure to the patient's arm, this invention features pressure-applying components fitted inside the upper arm support plate and forearm support plate, which dynamically apply pressure to the arm. This controlled pressure promotes venous return, reduces local edema, and allows for adjustment of the pressure intensity according to the rehabilitation process to assist muscle training and improve the patient's healing efficiency. To facilitate shoulder abduction, this invention includes a protruding structure on one side of the lumbar support plate that extends from the armpit to the elbow near the waist, ensuring a certain angle of shoulder abduction.

[0020] (2) Compared with the existing shoulder abduction brace which has a single fixed angle and cannot adapt to patients at different rehabilitation stages, this utility model is equipped with an abduction angle adjustment component. The abduction angle adjustment component is set between the arm support component and the waist support component to adjust the abduction angle of the shoulder to adapt to different rehabilitation stages and different patients, thereby improving the patient's healing efficiency.

The upper arm support rod is located at the lower part of the upper arm support plate, and the rack is located on one side of the waist support plate. The connecting rod connects the upper arm support rod and the gear. The gear moves on the rack to drive the end of the connecting rod and the upper arm support rod to extend and retract, thereby adjusting the abduction angle to suit different patients. The rack is provided with graduations for precise adjustment of the abduction angle.

[0022] (4) This utility model provides ratchet and pawl on both sides of the gear. The ratchet and pawl are coaxial with the gear, and the ratchet and pawl lock and unlock the gear's movement in two directions respectively. When the pawl is engaged between the teeth of the ratchet, the ratchet stops rotating, the gear also stops rotating, and the angle between the waist support and the arm support is locked; when the pawl disengages from between the teeth of the ratchet, the ratchet starts rotating, the gear also starts rotating, and the angle between the waist support and the arm support is unlocked.

[0023] (5) The pressurization component of this utility model includes a pressurization airbag, which is disposed on the inner side of the upper arm support plate and the lower arm support plate and is in contact with the skin of the arm, and can dynamically detect and adjust the pressure on the arm.

[0024] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing this invention. The objectives and other advantages of this invention can be realized and obtained from the details specifically pointed out in the text and accompanying drawings. Attached Figure Description

Detailed Implementation

[0034] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0035] Example 1

[0036] A specific embodiment of this utility model is as follows: Figure 1 As shown, an assistive tool for postoperative rehabilitation of shoulder joint injuries is disclosed, including a lumbar support component 1, an arm support component 2, and a pressure component 3.

[0037] The lumbar support assembly 1 includes a lumbar support plate 11, shoulder straps 12, an upper waist belt 13, and a lower waist belt 14.

[0038] The lumbar support plate 11 is in the shape of an arc-shaped groove, which is used to accommodate one side of the patient's waist. In order to accommodate patients with different trunk thicknesses, the lumbar support plate 11 is made of a material that is flexible but has a certain degree of rigidity. For example, the lumbar support plate 11 is an aluminum alloy, plastic or composite material.

[0039] Furthermore, in order to enable the shoulders to abduct, a protruding structure 111 is provided on the side of the waist support plate 11 near the arm, which extends outward towards the arm and abducts the shoulders at a certain angle. The protruding structure 111 extends from the armpit to the elbow near the waist, and the width of the protrusion under the armpit gradually increases from the elbow, so that the arm extends outward from the armpit all the way to the elbow, and the distance between the arm and the waist gradually increases.

[0040] Compared with the prior art, this embodiment has a protruding structure 111 on one side of the waist support plate 11 to abduct the shoulder, extending from the armpit to the elbow near the waist, to ensure that the shoulder abducts at a certain angle.

[0041] The shoulder strap 12 wraps around the shoulder and its two ends are connected to the front and rear of the waist support plate 11, respectively. The upper waist belt 13 is positioned between the waist and the chest, and the lower waist belt 14 is positioned at the waist. The shoulder strap 12, upper waist belt 13, and lower waist belt 14 are used to secure the waist support plate 11.

[0042] Furthermore, buckles 4 are provided on the shoulder straps 12, upper waist belt 13, and lower waist belt 14 to adjust their lengths to accommodate different patients. Buckles 4 are existing technology and will not be described in detail here. In this embodiment, buckles 4 are provided on the shoulder straps 12 and waist belts to adjust their lengths, making them suitable for individuals with different trunk thicknesses and chest widths, enhancing the fit of the abduction brace and improving the patient's experience.

[0043] like Figure 2 and Figure 3 As shown, the arm support assembly 2 includes an upper arm support structure 21, a forearm support structure 22, and a connecting strap. The connecting strap connects the upper arm support structure 21 and the forearm support structure 22. The upper arm support structure 21 includes an upper arm support plate 211 and an upper arm strap 212; the forearm support structure 22 includes a forearm support plate 221 and a forearm strap 222. Both the upper arm support plate 211 and the forearm support plate 221 are arc-shaped structures adapted to the shape of the arm. To accommodate patients with different arm circumferences, the upper arm support plate 211 and the forearm support plate 221 are made of a bendable material with a certain degree of rigidity. For example, the upper arm support plate 211 and the forearm support plate 221 are made of aluminum alloy, plastic, or a composite material.

[0044] The upper arm strap 212 is mounted on the upper arm support plate 211, and the lower arm strap 222 is mounted on the lower arm support plate 221, which are used to fix the upper arm support plate 211 and the lower arm support plate 221, respectively.

[0045] The pressurization assembly 3 is used to pressurize the arm. The pressurization assembly includes a pressurization airbag 31 and a control panel 32. The pressurization airbag 31 is located inside the upper arm support plate 211 and the lower arm support plate 221, and can dynamically detect and adjust the pressure on the arm. Specifically, the length direction of the pressurization airbag 31 is the same as the length direction of the upper arm support plate 211 and the lower arm support plate 221, and it is located at the inner center of the upper arm support plate 211 and the lower arm support plate 221, fitting snugly against the arm.

[0046] The control panel 32 is located externally and has a display screen, an on / off switch, and a timer button. The display screen shows the real-time pressure on the arm.

[0047] For example, the pressure airbag 31 is attached with Velcro, and the pressure component 3 can be removed when not in use and replaced with a material such as cotton cloth to reduce pressure on the skin.

[0048] Compared to existing assistive tools for postoperative rehabilitation of shoulder joint injuries that lack a pressure component 3 and cannot perform pressure detection and application to the patient's arm, this embodiment has a pressure airbag 31 fitted inside the upper arm support plate 211 and the forearm support plate 221, which is used to dynamically apply pressure to the arm. This promotes venous return through controllable pressure, reduces local edema, and can adjust the pressure intensity according to the rehabilitation process to assist muscle training and improve the patient's healing efficiency.

[0049] Example 2

[0050] To improve patient comfort and allow for adjustment of the shoulder abduction angle to accommodate patients at different stages of rehabilitation, such as... Figure 4 As shown, this embodiment removes the protruding structure 111 of the waist support plate 11 based on embodiment 1, and sets up an outward angle adjustment component 5.

[0051] To reduce discomfort in the armpits and elbows caused by the protruding structure 111 of the lumbar support plate 11, the lumbar support plate 11 is designed to be vertical on the side near the arm without the protruding structure 111.

[0052] An abduction angle adjustment component 5 is provided between the lumbar support component 1 and the arm support component 2 for adjusting the shoulder abduction angle. Figure 5 and Figure 6 As shown, the outward angle adjustment assembly 5 includes a rack 51, a boom support rod 52, a connecting rod 53, and a gear 54.

[0053] The rack 51 is fixed to one side of the waist support plate 11. The length direction of the rack 51 is the same as the height direction of the waist support plate 11.

[0054] Furthermore, in order to adjust the outward angle more precisely, the rack 51 is provided with a scale along its length.

[0055] The boom support rod 52 is located at the lower part of the boom support plate 211. The end of the boom support rod 52 is hinged to the end of the rack 51. The boom support rod 52 can rotate around the hinge axis at the hinge point. The angle between the boom support rod 52 and the rack 51 is the shoulder abduction angle.

[0056] One end of the connecting rod 53 is hinged to the boom support rod 52, and the other end is connected to the gear 54. The gear 54 meshes with the rack 51 and can move along the rack 51. The movement of the gear 54 can drive the end of the connecting rod 53 to move, thereby pulling or pushing the boom support rod 52 to rotate at the hinged end of the connecting rod 53, so as to increase or decrease the shoulder abduction angle.

[0057] Compared to existing assistive devices for shoulder joint post-operative rehabilitation with a single fixed angle, which cannot adapt to patients at different rehabilitation stages, this embodiment includes an abduction angle adjustment component 5. The abduction angle adjustment component 5 is positioned between the arm support component 2 and the lumbar support component 1, and is used to adjust the shoulder abduction angle to accommodate different rehabilitation stages and different patients, thereby improving patient healing efficiency. The abduction angle adjustment component 5 in this embodiment includes an upper arm support rod 52, a connecting rod 53, and a gear 54 and rack 51 structure. The upper arm support rod 52 is located at the lower part of the upper arm support plate 211, and the rack 51 is located on one side of the lumbar support plate 11. The connecting rod 53 connects the upper arm support rod 52 and the gear 54. The movement of the gear 54 on the rack 51 drives the end of the connecting rod 53 and the upper arm support rod 52 to abduct and retract, thereby adjusting the abduction angle to suit different patients. The rack 51 has graduations along its length for precise adjustment of the abduction angle.

[0058] To lock the outward angle, the outward angle adjustment assembly 5 also includes a ratchet 55 and a pawl 56. The ratchet 55 and pawl 56 are located on both sides of the gear 54. The ratchet 55 and pawl 56 on both sides are used to stop the gear 54 from rotating forward or backward, respectively.

[0059] Ratchet 55 is located on the side of gear 54 and is integral with gear 54. Pad 56 is movable along the axis of gear shaft; specifically, pad 56 is made of a retractable material. When pad 56 is pressed down, pad 56 engages between the teeth of ratchet 55, and ratchet 55 stops rotating; when pad 56 is moved up, pad 56 disengages from ratchet 55, and ratchet 55 begins to rotate.

[0060] In this embodiment, ratchet 55 and pawl 56 are provided on both sides of gear 54. The ratchet 55 is located on the side of gear 54 and is integral with gear 54. Pawl 56 is coaxial with gear 54. The ratchet 55 and pawl 56 are used to lock and unlock the movement of gear 54 in two directions, respectively. When pawl 56 engages between the teeth of ratchet 55, ratchet 55 stops rotating, gear 54 also stops rotating, and the angle between waist support plate 11 and arm support 2 is locked; when pawl 56 disengages from between the teeth of ratchet 55, ratchet 55 begins to rotate, gear 54 also begins to rotate, and the angle between waist support plate 11 and arm support 2 is unlocked.

[0061] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
