Description

Technical Field

[0001] The present invention relates to the technical field of spinal external fixation braces, and in particular to a group of novel spinal external fixation braces. Background Art

[0002] An external spinal fixation brace is a common medical brace used for conservative treatment of spinal fractures or auxiliary rehabilitation after spinal surgery. It mainly limits abnormal movement of the spine through external support and fixation, provides a stable environment for the damaged spine, and promotes its repair and rehabilitation. With the continuous advancement of medical technology, the demand for the comfort and functionality of fixation braces is also increasing.

[0003] Existing external fixation braces are mostly composed of two front and rear fixed support plates, a tightening belt and internal padding. Although they can meet basic daily use needs, they have some disadvantages in actual use. When the user wears the brace, the neck support part often makes it difficult to open the mouth to eat, which seriously affects the comfort of use. At the same time, the brace cannot fully cover the cervical and thoracic segments, resulting in poor support effect for the cervical and thoracic segments, making it difficult to ensure the treatment effect. Moreover, for patients with obesity and abdominal distension, the existing waist circumference external fixation not only cannot achieve a close fit, but is also likely to aggravate the abdominal compression and discomfort, resulting in a significant reduction in the rehabilitation effect.

[0004] Therefore, in order to solve the problems that the neck support part of the existing external fixation brace causes difficulty in eating and affects comfort, and the protection of the cervical and thoracic segments cannot be fully covered, resulting in poor support effect of the cervical and thoracic segments, and the poor waist fit of patients with obesity and abdominal distension easily aggravates the abdominal compression discomfort, a new set of spinal external fixation braces was proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a set of novel spinal external fixation braces to solve the problem that the neck support part of the existing external fixation brace causes difficulty in eating and affects comfort, and at the same time cannot fully cover the protection of the cervical and thoracic segments, resulting in poor support effect for the cervical and thoracic segments, and the poor waist fit for obese and abdominally bloated patients easily aggravates the abdominal compression discomfort.

[0010] Preferably, the neck support assembly includes a connecting sleeve, a movable inner rod, a positioning hole groove, a fastening bolt, a head strap, a feeding port, a magnetic strap, a magnetic docking strap, a lower neck clamp and a connecting strap. The upper end of the rear lumbar plate of the brace is hinged with a connecting sleeve, and the interior of the connecting sleeve is slidably connected to the movable inner rod.

[0011] Preferably, a positioning hole groove is provided at the side end portion of the movable inner rod, a fastening bolt is threadedly connected to the inside of the side end of the connecting sleeve, and the fastening bolt passes through the connecting sleeve and is threadedly connected to the inside of the positioning hole groove.

[0012] Preferably, the dorsal end of the back head support plate is symmetrically connected to a head strap, and the side end of the chin support plate is provided with a feeding opening.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By creating a special feeding port inside the mandibular support plate in the fixed brace and adopting an opening and closing design of the magnetic strap and the magnetic docking strap, patients can open their mouths normally to eat without removing the neck brace. Simply loosening the magnetic strap can properly restore the mandibular movement to meet the patient's mouth opening needs, breaking the limitation of the traditional neck brace's complete wrapping, allowing patients to open their mouths normally to eat while wearing it, significantly improving comfort and wearing experience.

[0018] 2. Through the adjustable connecting sleeve and movable inner rod, in conjunction with the back head support plate, chin support plate and neck lower clamping plate, and combined with the M-shaped tie structure composed of cross chest straps and horizontal fixing straps, a three-dimensional neck and chest support structure is formed to make up for the defect of insufficient coverage of existing chest external fixation, effectively enhance the support and protection effect of the neck and chest segment, and ensure the treatment effect.

[0019] 3. Through the combination of elastic steel plates and movable hinge plates, the front chest plate of the brace can adaptively deform according to the patient's body shape, especially the curves of obese patients and those with abdominal distension. Combined with the multiple adjustment structures of the horizontal fixing belt, length adjustment buckle and upper and lower waist straps, a tight and uniform fit is achieved, which releases the pressure on the abdomen, avoids the local compression of the abdomen by traditional waist belts, and reduces patient discomfort.

[0041] The side ends of the chin support plate 5 and the back of the head support plate 6 are both provided with connecting through holes, and the inside of the connecting through holes is provided with connecting straps 510. The connecting straps 510 make the chin support plate 5 and the back of the head support plate 6 form a whole, thereby strengthening the support for the patient's neck.

[0042] Working principle: According to Figures 1-8 First, when the patient wears the brace, the front chest plate 1 of the brace is fitted to the chest, and the back waist plate 3 of the brace connected by the cross chest strap 2 is wrapped around the patient's back. The transverse fixing belt 4 is hinged to the inside of the cross chest strap 2, which can be tightened and fixed to the torso laterally. The length adjustment buckle 7 on the outside of the cross chest strap 2 is used to adjust the tightness of the chest strap to ensure that it fits the patient's body shape. At the same time, the waist strap 112 on the inside of the back waist plate 3 of the brace passes through the through slot 111 at the side end of the front chest plate 1 of the brace, and is connected to the back waist plate 3 of the brace through the Velcro hook surface. The Velcro adhesive surface 113 on the side is connected to further strengthen the waist fixation and achieve preliminary stable support for the thoracic and lumbar spine. Then the six elastic steel plates 102 are slidably installed on the inner side of the front chest plate 1 of the brace through the installation connecting sleeve 101. The movable hinge plate 103 realizes the flexible articulation of adjacent steel plates, which can adapt to the patient's body curve. The lining breathable plate 107 is fixed to the elastic steel plate 102 and the front chest plate 1 of the brace through the docking clamp rod 108 and the locking column 109, which not only ensures the fit but also improves the breathability.

[0043] according to Figures 8-10 , Then the connecting sleeve 501 is hinged to the upper end of the rear lumbar plate 3 of the brace, and the movable inner rod 502 can slide up and down in the connecting sleeve 501, and is threadedly connected to the positioning hole groove 503 at the side end of the movable inner rod 502 through the fastening bolt 504 through the connecting sleeve 501 to adjust and lock the neck support height, and the chin support plate 5 and the back of the head support plate 6 are fixed to the patient's head and neck through the head strap 505 and the connecting strap 510. The feeding port 506 at the side end of the chin support plate 5 ensures that the patient can eat normally, and the magnetic strap 507 and the magnetic docking strap 508 are convenient for quick opening and closing adjustment. In addition, the neck lower clamping plate 509 at the lower end of the chin support plate 5 is placed on the inner side of the cross chest strap 2, and cooperates with the back of the head support plate 6 and the spine support keel plate 110 on the rear lumbar plate 3 of the brace to form a three-dimensional support for the cervical and thoracic segment, limit abnormal spinal movement, and provide stable protection for cervical and thoracic segment injury or postoperative rehabilitation.
