Description

Technical Field

[0001] The utility model relates to the technical field of kyphosis correction surgical instruments, in particular to a body position reduction bracket used for kyphosis correction. Background Art

[0002] Kyphosis correction surgery, also known as kyphosis correction surgery, is a surgical treatment for kyphosis. This procedure primarily corrects kyphosis caused by ankylosing spondylitis, trauma, tuberculosis, and other conditions. The core of the surgery involves amputating the kyphotic portion of the spine through osteotomy and realigning it to restore the spine's normal physiological curvature. During kyphosis correction surgery, after osteotomy and release of the apex of the kyphosis, the kyphosis angle is reduced by raising the upper body or lowering the trunk under the influence of gravity, using the apex as the center of rotation. This process is called postural reduction.

[0003] Existing technology uses a foldable operating table to achieve repositioning. Specifically, the patient lies prone on the table, with the apex of the patient's kyphosis roughly aligned with the table's foldable rotation axis. When repositioning is required, the kyphosis is restored by adjusting the table's folding angle and direction.

[0004] However, current foldable operating tables only have one rotating joint, so the surface formed after folding is difficult to evenly contact the ventral body surface of patients with varying degrees of kyphosis, which can easily lead to excessive local stress and damage to the skin or internal organs. It is also difficult to use for some patients with severe spinal kyphosis who require a high degree of folding, and the adjustment force is difficult to control. Excessive or rapid adjustment may cause damage to the patient's spine. Summary of the Invention

[0026] The present invention provides a spinal kyphosis correction body position reduction support 100, see Figure 1 、 Figure 2 and Figure 3The postural repositioning support 100 for kyphosis correction includes a guide base 110, a first support assembly 120, a second support assembly 130, and a repositioning assembly 140. A first pulley 121 is provided at one end of the first support assembly 120. The first pulley 121 slidably engages with the guide base 110 and can slide along the length of the guide base 110. A second pulley 131 is provided at one end of the second support assembly 130. The second pulley 131 slidably engages with the guide base 110 and can slide along the length of the guide base 110. The reduction assembly 140 includes a first connecting rod 141, a second connecting rod 142, a reduction cross bar 143, and a first rotary joint 144. The first connecting rod 141 is movably connected to the end of the first support assembly 120 away from the guide seat 110. One end of the second connecting rod 142 is movably connected to the end of the second support assembly 130 away from the guide seat 110. The other ends of the first connecting rod 141 and the second connecting rod 142 are both rotationally connected to the reduction cross bar 143 and are fastened together via the first rotary joint 144. Furthermore, the kyphosis correction support 100 also includes a cushion 150, which is disposed on the side of the first support assembly 120, the reduction assembly 140, and the second support assembly 130 facing away from the guide seat 110.

[0027] It should be noted that the sliding directions of the first pulley 121 and the second pulley 131 are opposite.

[0028] The working principle and beneficial effects of the above technical solution are as follows: During use, the present reduction bracket is first assembled based on the patient's kyphosis angle by first and second support assemblies 120, 130, and first and second connecting rods 141, 142 on the reduction assembly 140. This ensures that the bracket angle formed by the connecting rods is approximately equal to the patient's degree of kyphosis. Next, a cushion 150 is placed on the reduction crossbar 143. The surface of the cushion 150 on the bracket is similar to the morphology of the patient's ventral body surface. Therefore, when the patient lies prone, their ventral body surface can be evenly contacted with the surface of the cushion 150, avoiding excessive localized stress. When the patient needs to reposition during surgery, the first rotary joint 144 is gradually partially loosened, creating some slack between the first and second connecting rods. The degree of slack allows the first rotary joint 144 to rotate freely. Under the action of gravity, the first pulley 121 and the second pulley 131 gradually slide toward opposite sides of the guide seat 110, and the first rotary joint 144 gradually descends, ultimately achieving kyphosis reduction.

[0029] This reduction brace adjusts the brace joints to achieve an overall shape that is close to the patient's kyphosis shape. This adjustment can be personalized to meet the needs of different kyphosis patients, ultimately ensuring that the ventral skin is evenly stressed after the patient lies down. This is especially useful for patients with severe kyphosis who cannot lie down on existing folding operating tables. During the position reduction process, this brace relies on the gradual loosening of the first rotating joint 144 and gravity to gradually reduce its position. Compared with traditional methods, this method is more gentle, stable, and controllable, helping to avoid damage to the spine. For details, please refer to Figure 1 and Figure 2 There are two first connecting rods 141 and two second connecting rods 142. Two first rotating portions 122 are provided at one end of the first support assembly 120 at intervals along the width direction of the guide base 110. Two second rotating portions 132 are provided at one end of the second support assembly 130 at intervals along the width direction of the guide base 110. One end of the two first connecting rods 141 is movably connected to the first rotating portion 122, and one end of the two second connecting rods 142 is movably connected to the second rotating portion 132. The two first connecting rods 141 and the two second connecting rods 142 are rotatably connected to opposite ends of the reset cross bar 143 and are tightly fitted together via a first rotary joint 144.

[0030] The working principle and beneficial effects of the above technical solution are: the structure is stable and sliding is achieved at both ends to ensure the stability of the support for the patient's body.

[0031] In order to further understand and explain the length direction and width direction of the guide seat 110, Figure 2 For example, the length direction of the guide seat 110 is Figure 2 The direction indicated by any arrow on the center line S1 is the width direction of the guide seat 110. Figure 2 In the direction indicated by any arrow on the center line S2 , the length direction of the guide seat 110 is perpendicular to the width direction.
