Description

Technical Field

[0001] The present invention relates to the technical field of spinal fixation equipment, and in particular to a spinal post-operative fixation device. Background Art

[0002] The spine is the pillar of the body. The upper end supports the skull, the lower end is connected to the hip bone, the middle end is attached to the ribs, and it serves as the posterior wall of the thorax, abdomen and pelvis. The spine has the function of supporting the trunk, protecting the internal organs, protecting the spinal cord and performing movements. Therefore, it can be said that the spine is one of the most important components of the human skeleton. In daily life, some people will suffer spinal injuries due to collisions, falls or diseases. In order to avoid the development of injuries that lower the patient's subsequent quality of life, corresponding treatments are generally taken, including surgical treatment.

[0003] After surgical treatment, patients also need to perform appropriate postoperative rehabilitation exercises. During the rehabilitation exercise, the spine must be fixed to prevent secondary injury to the spine due to incorrect exercise posture. The current method of fixing the spine of patients in the rehabilitation period is usually to place two splints on the front and back sides of the patient respectively, and then connect the two with straps to provide support for the patient's upper body.

[0004] Although the existing method is easy to use, its fixation effect is limited, and it will also cause pressure on the patient's chest, causing the patient's breathing difficulties.

A neck plate 28 is provided between the two shoulder plates 16. The neck plate 28 is a two-thirds elliptical ring structure with the open end facing forward. Two protection pads 29 are symmetrically sleeved on the inner wall of the neck plate 28. The protection pads 29 are arc structures with a U-shaped cross section. Two elastic ropes 30 are symmetrically fixedly provided on the outer wall of the protection pad 29 relative to the outer side of the neck plate 28. A lifting seat 31 is fixedly provided on the rear wall of the neck plate 28. A guide rod 32 is slidably connected to the middle part of the bottom surface of the lifting seat 31. A rotating ball 33 is coaxially fixedly connected to the lower end of the guide rod 32. A ball groove 34 rotatably matched with the rotating ball 33 is provided on the top surface of the fixed seat 1. A rotating rod 35 is hinged between the middle part of the top surface of the sliding seat 22 and the side wall of the lifting seat 31.

[0038] A cavity 3 is provided inside the fixing seat 1, a supporting groove 4 is provided on the front wall of the fixing seat 1, and an adjusting mechanism 5 is provided at the rear of the fixing seat 1. The adjusting mechanism 5 includes an internally threaded tube 6 which passes through and is fixedly provided in the middle of the rear wall of the fixing seat 1, and a threaded rod 7 is connected to the internal thread of the internally threaded tube 6. The front end of the threaded rod 7 passes through the internally threaded tube 6 and extends into the cavity 3 and is coaxially provided with a circular groove 8. A telescopic rod 9 is coaxially fixedly provided on the rear wall of the circular groove 8, and the front end of the telescopic rod 9 is connected and fixed to the front wall of the cavity 3. A compression spring 10 is sleeved on the outer wall of the telescopic rod 9, and a plurality of supporting springs 12 are fixedly provided on the upper and lower sides of the inner wall of the cavity 3. The supporting groove 4 is an arc-shaped structure with the same curvature as the curvature of the human spine, and a rubber rod 13 is fixedly provided on the inner wall of the supporting groove 4 relative to the position of each section of the human spine, and a swivel 14 is coaxially rotatably connected to the rear of the threaded rod 7, and two supporting rods 15 are symmetrically fixed on the upper and lower outer walls of the swivel 14, and the support rod 15 is arranged in an arc-shaped structure and the outer end is connected and fixed to the rear wall of the fixing seat 1.

[0039] Working principle: The patient can match his own spine with the support groove 4 on the fixing seat 1 of the device. Because the support groove 4 is adapted to the curvature of the spine, the inner wall of the support groove 4 can completely fit on the patient's back, and a large number of rubber rods 13 arranged on the inner wall of the support groove 4 correspond to the position of each spine of the patient one by one, so that each spine can have a one-to-one support effect. The fixing seat 1 itself is also made of rubber, so the rubber rods 13 and the fixing seat 1 will not have hard contact with the patient's body surface to cause injury to the patient;

[0040] After the positions are matched, the patient can match the position of the waist plate 36 in the fixing mechanism 11 with the position of his own lower back. After matching, the straps 38 on both sides are wound around the lower abdomen and the four straps 38 are fixed by the mutual bonding effect of the Velcro sub-strip 41 and the Velcro mother-strip 42. The two straps 38 on the same side are connected by an elastic band 39, so as to adapt to the waist circumference of different patients and improve the flexibility of the device. Furthermore, a support plate 40 is provided on the strap 38, and the support plate 40 can prevent the strap 38 and the elastic band 40 from bending in the middle, so as to protect and support the patient's waist and a section of the spine near the coccyx.

[0041] On the other hand, the patient also needs to adjust the position of the shoulder plate 16 to correspond to his or her own shoulder, and the shaft 25 can be rotated by turning the hand wheel dial 37, and then the sliding seat 22 will move under the squeezing of the guide block 27 by the spiral groove 26 on the shaft 25. The sliding seat 22 is restricted by the limit frame 23 and can only move up and down. Therefore, it will drive the shoulder plate 16 to move up and down during the rotation of the shaft 25. Under the action of this structure, the patient can adjust the two shoulder plates 16 separately. During the adjustment, the rotating rod 35 on the top surface of the sliding seat 22 will also affect the lifting seat 31, and then the lifting seat 31 drives the neck plate 28 to move up and down or deflect the angle. The bottom surface of the lifting seat 31 is slidably connected and rotated with the fixed seat 1 through the rotating ball 33, the guide rod 32 and the ball groove 34, so the up and down movement and angle change can be easily completed. The method is not only convenient for adapting to the body shapes of different patients, but also makes the device suitable for patients with high and low shoulders. Because the shoulders of patients with high and low shoulders are at different levels, the neck will also be distorted under this influence. By adjusting the height of the two shoulder plates 16 to change the neck plate 28, the distortion of the patient's neck can be adapted. In rehabilitation treatment, the horizontal heights of the two shoulder plates 16 can be gradually adjusted to a consistent height to restore the patient's high and low shoulder problem. After the patient has matched the shoulder plates 16 with the shoulders, the elastic band 18 can be pulled to the position of the strap 38, and the safety buckle 19 can be snapped into the safety buckle female buckle 43. In this way, the device is fixed to the patient's body surface. Through the partition 20 set on the front wall of the shoulder plate 16, the elastic band 18 can maintain a certain distance from the patient's chest to prevent the elastic band 18 from compressing the patient's chest and causing discomfort.

[0042] After the device is fixed, the patient can adjust the fixing seat 1 with the help of medical staff or family members, and the threaded rod 7 can be twisted from the rear to make it move forward and backward along the internal threaded tube 6. During the movement, it will drive the telescopic rod 9 to tighten, and the threaded rod 7 is rotatably connected to two support rods 15 through a swivel 14. The support rod 15 is fixed to the rear part of the fixing seat 1 in an eight-shaped shape. Under such a structure, the support rod 15 can produce a supporting effect on the overall shape of the fixing seat 1. Through the squeezing and pulling of the threaded rod 7, the angle between the two support rods 15 will tend to 180 degrees. As the angle increases, the upper and lower ends of the fixing seat 1 will also bend backwards. On the contrary, the upper and lower ends of the fixing seat 1 will bend forwards under the toughness of the support rod 15. In this way, the fixing seat 1 can be suitable for patients with different spinal curvatures. This is not only to adapt to the patient's posture, but also to the conditions of different patients, thereby producing a gradual rehabilitation treatment effect.

[0043] It is worth mentioning that, in addition to the support spring 12 for supporting the fixing seat 1 and reducing the contact strength between the fixing seat 1 and the patient, the cavity 3 also has a telescopic rod 9 and a compression spring 10 fixed in the circular groove 8 on the threaded rod 7. The buffering effects produced by the two during the movement of the threaded rod 7 are also inconsistent. When the patient's middle spine is severely flexed, the support strength that can be accepted is also limited. At this time, the position of the threaded rod 7 is relatively backward, and the compression spring 10 is naturally in a relatively relaxed state. The buffering space that can be provided to the patient within its elastic limit will also be larger. When the patient is in the later stage of recovery, the situation is the opposite. Such a design further improves the protection of the patient by the device.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
