Description

Technical Field

[0001] The present invention relates to the field of medical fixation equipment, and in particular to a fixation device for shoulder joint subluxation caused by hemiplegic shoulder. Background Art

[0002] Hemiplegic shoulder is a limb paralysis caused by the sequelae of stroke. After the shoulder joint muscles are paralyzed, the humerus cannot be lifted, which is called shoulder subluxation. Once a patient has hemiplegic shoulder, it will seriously affect the patient's rehabilitation treatment process. If the shoulder subluxation range exceeds one finger, the clinical prognosis is poor. Therefore, once the shoulder subluxation occurs, preventing complications and further aggravation of the condition is as important as treatment. At present, shoulder braces (shoulder protectors / shoulder fixators) are mainly used for protection and treatment of hemiplegic shoulder patients with shoulder subluxation in clinical practice. However, the shoulder braces currently on the market only fix the shoulder joint, and the reduction of shoulder subluxation and the protection and treatment of good limb position and limb functional position are not obvious. There is a lack of consideration of biomechanics and human kinematics; and the wearing is complicated, resulting in low patient compliance. In addition, the price is also relatively expensive, which also adds unnecessary economic burden. Summary of the invention

[0003] The purpose of the present invention is to provide a shoulder joint subluxation fixation device caused by hemiplegic shoulder, which has a simple structure, is easy to use, and has the protective effects of both good limb position and limb functional position during reduction treatment.

[0004] To achieve the above-mentioned purpose of the invention, the technical solution adopted by the present invention is: a device for fixing shoulder subluxation caused by hemiplegic shoulder, comprising an elastic band and a palm support; the elastic band has a palm sleeve area for the patient's palm to grip, and the palm support is fixed to the palm sleeve area; the elastic band also has a wrist back crossing area that forms a cross on the back of the patient's wrist, an elbow inner crossing area that forms a cross on the inner side of the patient's elbow joint, a back crossing area that forms a cross in the middle of the patient's back scapula, and a shoulder fixing area that passes through the armpit and is connected to the other shoulder of the patient.

[0005] Preferably, the elastic band is a high-elastic bandage.

[0006] Preferably, the palm support is a cylindrical column for the patient to hold with his hand, and the column is wrapped in a high-elastic bandage to be fixed.

[0008] The elastic bands are provided with two ends, one end of the two elastic bands is connected to the two reels, and the other end passes through the band opening and is connected to the palm support member;

[0009] The belt opening is also provided with a clamping block which can slide along the belt opening in an up-and-down direction. The bottom of the belt opening is threadedly connected with an adjusting bolt. The inner end of the adjusting bolt is opposite to the clamping block and can push the clamping block to clamp the elastic belt.

[0010] Preferably, the palm support is a 3D-printed resin component adapted to the physiological morphology of the patient's palm.

[0021] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings. The embodiments described are only part of the embodiments of the present invention, rather than all of the embodiments, and are intended to provide those skilled in the art with better implementation in engineering rather than to limit the use of the present invention.

[0022] The key point is to achieve a fixation of the shoulder joint subluxation caused by hemiplegic shoulder in a more human kinematic and biological manner through a specific elastic band multi-point cross fixation form, thereby improving the therapeutic effect of the shoulder joint subluxation caused by hemiplegic shoulder. A fixation device for shoulder joint subluxation caused by hemiplegic shoulder, comprising an elastic band 1 and a palm support 2. The simplest elastic band 1 can be a roll of high-elastic bandage, and the palm support 2 is a cylindrical column for the patient to hold, such as a cardboard column, a plastic column, etc. The column is wrapped in a high-elastic bandage to form a fixation.

[0023] Combination Figure 2 It can be seen from the simplified display that the elastic band 1 has a palm area for the patient to hold the palm, and the palm support 2 is fixed to the palm area. The elastic band 1 also has a wrist back cross area that forms a cross on the back of the patient's wrist, an elbow inner cross area that forms a cross on the inner side of the patient's elbow joint, a back cross area that forms a cross in the middle of the patient's back shoulder blade, and a shoulder fixing area that passes through the armpit and is sleeved on the other shoulder of the patient.

[0024] When the simplest method described above is used as the elastic band 1 through a high elastic bandage, and a simple column assembly is used to form a fixing device, the construction method is as follows: the bandage passes through the palm and covers the column held by the patient to improve comfort and form a palm sleeve area. Then the bandage is crossed for the first time on the back of the wrist to form a wrist back crossing area, promote wrist dorsiflexion, maintain the wrist joint in a functional position, and prevent wrist flexion contracture limitation. After that, it passes through the elbow joint and forms a second cross on the inner side of the elbow joint, thereby forming an inner elbow crossing area to promote elbow straightening. The bandage on the front side needs to be tightened to promote forearm external rotation. After that, one end of the bandage passes from the front of the shoulder to the back, and the other end passes from the armpit of the shoulder blade to the back, forming a third cross between the two shoulder blades on the back of the shoulder to form a back crossing area. The bandage is wrapped around the shoulder joint on the other side for fixation to form a shoulder fixation area.

[0025] In this form, the bandage passing through the front of the shoulder can prevent the humeral head from moving forward. The third cross formed between the two shoulder blades behind the shoulder can fix the shoulder blades and ensure the accuracy of shoulder girdle movement. At the same time, the elastic force from bottom to top generated by the entire bandage can promote the shoulder joint to return to the correct joint position and avoid further aggravation of shoulder subluxation. At the same time, fixing both shoulders can increase the stability of the bandage.

[0026] Of course, when constructing the fixing device, the above-mentioned high-elastic bandage directly used as the elastic band needs to be crossed and wrapped manually. In addition to the above method, the elastic band can also be directly processed and sewn into a specific shape to achieve wearing. However, this method is a one-piece form. When wearing, the upper limb must be completely passed through multiple crossing areas and finally worn to the palm area. This form is to some extent contrary to the original intention of the present invention to facilitate use. At the same time, due to the relatively large volume, it is not convenient to store.

[0027] To this end, a better embodiment of the present invention can be as follows Figure 3 As shown in the figure, the form that can be adopted is that the shoulder fixing area is provided with an inverted V-shaped underarm plate 3, which is clamped under the armpit on the opposite side of the shoulder that needs to be reset when in use. Its special arc design can ensure comfort and prevent the compression caused by the end of the elastic band. Its overall construction idea also requires the operating physician to wrap it around the patient, but its elastic band 1 is in a retractable form, which is not only smaller in size, but also more convenient in operation.

[0028] like Figure 3 As shown in the figure, a cylindrical mounting shell 4 is provided inside the armpit plate 3, and a belt opening 5 for the elastic belt 1 to pass through is provided at the front and rear ends of the mounting shell 4. Two reels for winding up the elastic belt 1 are provided at the front and rear ends of the mounting shell 4, and a torsion spring for driving the reels to wind up the elastic belt 1 is provided at the reels. Two elastic belts 1 are provided, one end of the two elastic belts 1 is connected to the two reels, and the other end passes through the belt opening 5 and is connected to the palm support 2.

[0029] When in use, first clamp the armpit plate 3 on the opposite side, then pull the elastic band 1 out of the mounting shell 4, pull it to the patient's back, rotate it once to form a back cross zone, then wrap it around the patient's arm as a whole, rotate it once to form an elbow cross zone; then wrap it around the patient's arm, rotate it once to form a wrist cross zone, and then wrap the palm support piece around the patient's palm to cover it. In order to ensure comfort, if Figure 3 As shown in , the palm support 2 is preferably a 3D-printed resin component that matches the physiological morphology of the patient's palm, thereby ensuring the comfort of the palm during long-term wearing. Alternatively, it is also feasible to adopt an inherent design of the palm morphology that generally matches the majority of people, or it is also feasible to use a low-temperature thermoplastic material to mold the palm support 2.

[0030] Of course, after the entire fixing device is constructed, in order to ensure the stability of the overall length of the elastic band 1 and to prevent it from being disturbed by the torsion of the torsion spring at the reel, a better approach of the present invention is that a clamping block 7 capable of sliding along the upper and lower directions of the belt opening 5 is further provided in the belt opening 5, and an adjusting bolt 6 is threadedly connected to the bottom of the belt opening 5, and the inner end of the adjusting bolt 6 is opposite to the clamping block 7 and can push the clamping block 7 to clamp the elastic band 1.

[0031] In addition, since the cross-section of the present invention is constructed only when in use, in order to avoid discomfort caused by the elastic band 1 being bundled at the cross-section, while ensuring the stability of the cross-section, such as Figure 4 and 5 As shown, the present invention also includes a cross-zone fastener, which can be used in a single group or in multiple groups as required. The cross-zone fastener is composed of two waist-shaped buckle bodies 8 that are interlocked with each other. Two groups of female grooves 10 and male protrusions 9 are correspondingly provided on the opposite sides of the two buckle bodies 8, and the male protrusions 9 are inserted into the female grooves 10 to form an interference fit. The buckle body 8 is also provided with a plurality of spurs 11 on one side provided with the male protrusions 9. Through the cross-zone fastener, the cross stability at the cross-zone can be ensured, and at the same time, the elastic band 1 can be expanded as much as possible to improve comfort.

[0032] The above embodiments are only preferred embodiments of the present invention. Those skilled in the art may make appropriate modifications to the technical solutions provided by the present invention according to actual engineering practices, and the modifications and equivalent transformations made shall not depart from the scope of protection claimed by the present invention. The scope of rights claimed by the present invention shall be subject to the attached claims.
