Description

TECHNICAL FIELD

[0001] The utility model relates to a steel plate device for intervertebral disc herniation treatment, especially to an intelligent steel plate for artificially inducing natural shrinkage of herniated intervertebral disc, and belongs to one of medical devices. BACKGROUND

[0002] In the field of orthopedics, cervical and lumbar intervertebral disc herniation is a very common and frequently occurring disease. For a long time, in view of this kind of spinal degenerative disease, the clinic has developed a variety of treatment methods, and instruments such as steel plates are used as surgical or recovery devices. At the same time, artificial pedicle screw implantation internal fixation, robot navigation pedicle screw implantation internal fixation to stabilize the spine are involved; intervertebral disc resection fusion is to resect the diseased intervertebral disc and then fuse the intervertebral body.

[0003] In recent years, with the deepening of clinical research and the continuous innovation of imaging technology, people have been surprised to find that there is a phenomenon of natural shrinkage of herniated intervertebral disc in the process of conservative treatment. Although the incidence of this phenomenon is low, this discovery breaks the traditional cognition and proves that the herniated intervertebral disc is similar to the bone tissue and has the characteristics of "repairable".

[0004] In 2021, it was revealed that after minimally invasive endoscopic cervical double-door laminoplasty, the herniated intervertebral disc can occur extensive and efficient natural absorption phenomenon. In order to distinguish from the natural shrinkage phenomenon in the conventional conservative treatment, this postoperative natural shrinkage of the herniated intervertebral disc is named as "artificially induced natural shrinkage of the herniated intervertebral disc", which is simply called "artificially induced, disc recovery". The core of this technology is that no "direct" intervention is made to the herniated intervertebral disc during the operation, such as injecting drugs into the herniated intervertebral disc, inserting laser fibers for ablation, or performing herniated nucleus pulposus resection and other operations, but through symmetrical decompression of the vertebral plate, the spinous process ligament complex is moved backward, and then a micro titanium steel plate is used for fixation, so as to enlarge the spinal canal and improve the microenvironment of local ischemia and hypoxia of the spinal canal caused by intervertebral disc herniation, and then promote the natural shrinkage of the herniated intervertebral disc.

[0005] Inspired by the success of artificially induced natural shrinkage of cervical intervertebral disc herniation, significant breakthroughs have also been made in the field of lumbar intervertebral disc herniation. Lumbar "cohesive" symmetrical decompression artificially induced natural shrinkage of herniated intervertebral disc surgery has also been gradually applied in clinical practice. Research data shows that after lumbar "cohesive" symmetrical decompression artificially induced natural shrinkage of herniated intervertebral disc surgery, up to 94% of the herniated lumbar intervertebral discs can occur different degrees of shrinkage. At the same time, AI technology has also been successfully applied in assisting the measurement of the volume of the herniated intervertebral disc, which has key value for accurately evaluating the volume change of the herniated intervertebral disc and tracking the treatment effect.

[0006] Previous clinical studies have shown that during the process of bilateral lamina decompression groove bone healing in minimally invasive cervical double-door laminoplasty under endoscopy, various factors are released. These factors are most likely involved in the matrix metabolism of the herniated intervertebral disc, creating favorable conditions for the natural retraction of the herniated intervertebral disc.

[0007] As is known, the intervertebral disc is a structure located between the vertebrae of the human body and is mainly composed of the following parts:

[0008] 1. The annulus fibrosus is composed of multiple layers of fibrocartilage, with fibers arranged in a crisscross pattern, providing strength and elasticity, which bears pressure and limits the movement of the nucleus pulposus.

[0009] 2. The nucleus pulposus is a gelatinous substance rich in water and proteoglycans, which has the function of absorbing impact, maintaining the height and elasticity of the intervertebral disc.

[0010] 3. The cartilage endplate is a thin layer of transparent cartilage located above and below the intervertebral disc, connecting the vertebrae, which can provide nutrition and distribute pressure.

[0011] The intervertebral disc is composed of cells and extracellular matrix, and its cellular components include:

[0012] 1. Annulus fibrosus cells, mainly fibroblast-like cells, can synthesize and maintain the collagen and matrix of the annulus fibrosus.

[0013] 2. Nucleus pulposus cells include chondrocyte-like cells, which can synthesize and maintain the proteoglycans and collagen of the nucleus pulposus.

[0014] 3. Cartilage endplate cells, mainly chondrocytes, synthesize and maintain the matrix of the cartilage endplate.

[0015] At the same time, the cellular components of the intervertebral disc are responsible for the synthesis and maintenance of the extracellular matrix, which is the key to the structure and function of the intervertebral disc, mainly composed of the following components:

[0016] 1. Collagen fibers are mainly type I and type II collagen. The annulus fibrosus is mainly composed of type I collagen, which provides strength; the nucleus pulposus is mainly composed of type II collagen, which maintains elasticity.

[0017] 2. Proteoglycans, the main component such as aggrecan, attract and retain water, maintain the gelatinous structure of the nucleus pulposus and its resistance to compression.

[0018] 3. The nucleus pulposus has a high water content of about 70-90%, and the annulus fibrosus has a lower water content, which maintains the elasticity and compression resistance of the intervertebral disc. The production, maintenance and degradation of the extracellular matrix of the intervertebral disc are regulated by various factors.

[0019] Specifically, these factors include growth factors, cytokines and enzymes, etc.

[0020] 1. Growth factors play important roles in the proliferation, differentiation, and matrix synthesis of intervertebral disc cells. Transforming growth factor-β (TGF-β) promotes the synthesis of collagen and proteoglycans, inhibits inflammatory responses, maintains the homeostasis of intervertebral disc matrix, and promotes repair. Insulin-like growth factor-1 (IGF-1) stimulates the synthesis of proteoglycans and collagen, promotes cell proliferation and matrix production. Fibroblast growth factor (FGF) promotes cell proliferation and matrix synthesis, and is involved in the repair and regeneration of intervertebral discs. Bone morphogenetic protein (BMP) promotes chondrocyte differentiation and matrix synthesis, and plays an important role in the repair of intervertebral disc degeneration. Platelet-derived growth factor (PDGF) promotes cell proliferation and migration, and is involved in the repair process of intervertebral discs.

[0021] 2. Cytokines play a key role in intervertebral disc degeneration and inflammatory response. Interleukin-1 (IL-1) promotes the expression of matrix-degrading enzymes (such as MMPs), inhibits the synthesis of proteoglycans and collagen, and plays an important role in intervertebral disc degeneration. Tumor necrosis factor-α (TNF-α) induces inflammatory response, promotes matrix degradation, and accelerates intervertebral disc degeneration. Interleukin-6 (IL-6) is involved in inflammatory response and matrix degradation, and its expression is elevated in degenerative intervertebral discs. Interleukin-10 (IL-10) has anti-inflammatory effects, inhibits matrix degradation, and protects intervertebral disc matrix.

[0022] 3. Matrix-degrading enzymes are involved in the degradation of intervertebral disc matrix, and their activity imbalance can lead to intervertebral disc degeneration. Matrix metalloproteinases (MMPs) include MMP-1, MMP-3, and MMP-13, which degrade collagen and proteoglycans, and play a key role in intervertebral disc degeneration. Aggrecanases (ADAMTS) such as ADAMTS-4 and ADAMTS-5 specifically degrade proteoglycans (such as aggrecan), and play an important role in intervertebral disc degeneration.

[0023] 4. Matrix synthesis-promoting factors promote the synthesis of matrix components and maintain the health of intervertebral discs. Sox9 regulates the gene expression of type II collagen and aggrecan, promotes the differentiation of chondrocyte-like cells and matrix synthesis. Hypoxia-inducible factor-1α (HIF-1α) promotes cell survival and matrix synthesis in a low-oxygen environment, and maintains the metabolism and function of nucleus pulposus cells. Other regulatory factors such as NF-κB (nuclear factor κB) regulate the expression of inflammatory factors and matrix-degrading enzymes, and play an important role in intervertebral disc degeneration. The Wnt / β-catenin signaling pathway regulates cell proliferation and differentiation, and is involved in intervertebral disc degeneration and repair.

[0024] In summary, the homeostasis of intervertebral disc extracellular matrix is regulated by multiple factors, and the balance of these factors is crucial for the health of intervertebral discs. Imbalance may lead to intervertebral disc degeneration.

[0025] Previous studies have shown that during the process of intervertebral disc degeneration, the herniated disc which occupies the space of the spinal canal leads to local compression of the dural sac, and many metalloproteinases such as MMP-3 and Col1a genes show mechanical parameter-dependent expression, which can produce the effect of degrading extracellular matrix. After the operation of endoscopic minimally invasive cervical double-door laminoplasty, due to the reduction of local pressure in the spinal canal, the mechanical-dependent cell pathway is blocked, forming a protection for the extracellular matrix. β-collagen special sequence (β-CTx) is a collagen type I C-terminal peptide fragment, which contains an octapeptide composed of glutamic acid-lysine-alanine-histidine-β-aspartic acid-glycine-glycine-arginine (EK-ADH-β-GGR). Current studies believe that it is a reliable biochemical indicator for evaluating bone absorption. When the bone turnover rate in the human body increases and bone resorption significantly increases, the degradation of type I collagen also increases, and the content of β-CTx as a degradation fragment in the blood also increases. The bone healing of the human body generally experiences four stages: hematoma organization period, callus formation period, bone healing period, and bone plasticity period. The bilateral lamina decompression groove formed by the endoscopic minimally invasive cervical laminoplasty may release a large amount of β-CTx around 1 week after the operation, and the concentration of β-CTx in the peripheral blood may be significantly increased. The high concentration of β-CTx exists and participates in the metabolism of the extracellular matrix of the herniated disc. Since CTx is the degradation product of mature collagen fibers under catalytic conditions such as metalloproteinase (MMP), it reflects the activity of bone metabolic enzymes. The stage-by-stage increase represents the overall level of bone metabolism, and in the corresponding long-term stage, the expression level of bone metabolic synthesis enzymes such as synthesis enzymes is also higher, and the level of collagen fibers and glycosaminoglycan synthesized by the nucleus pulposus cells in the intervertebral disc is increased, and the fiber structure of the extracellular matrix is enhanced, thereby ensuring that the height and strength of the retracted intervertebral disc maintain the preoperative level after the intervertebral disc structure experiences the process of "degeneration-herniation-retraction". Previous studies have also found that the nucleus pulposus cells can mechanically respond to enzyme secretion to regulate the composition of the extracellular matrix, and these enzymes can induce the natural retraction of the herniated disc.

[0026] Most of the herniated discs are degenerative nucleus pulposus tissue, which is composed of nucleus pulposus cells and extracellular matrix, and the extracellular matrix is a reticular structure composed of type II collagen / proteoglycan, which contains SO4-glycosaminoglycan chains that absorb water to form the mechanical properties and structural basis of the intervertebral disc. After the compression force (2 MPa) stimulates the nucleus pulposus cells for 4 h and then removes it for 20 h, the expression of iNOS increases. Similarly, in chondrocytes, after the tensile physical mechanical stimulation (7.5%, 1 Hz) is maintained and then removed, the expression activity of metalloenzymes such as MMP-3, MMP-13, ADAMTS-4, and ADAMTS-5 is significantly increased.

[0027] However, the steel plate currently used for fixing the spinous process ligament complex in the minimally invasive cervical spinal canal enlargement under endoscopy is only a common micro titanium alloy steel plate. Although such a steel plate can provide support and fixation to assist bone healing of the decompression groove, it cannot "actively participate" in the process of artificially inducing the natural retraction of the protruding intervertebral disc. Therefore, it is difficult to effectively improve the retraction rate of the protruding intervertebral disc and the treatment effect.

[0028] In view of the above-mentioned defects, the present design person actively researches and innovates to create an intelligent steel plate for artificially inducing the natural retraction of the protruding intervertebral disc, so as to make it more useful in industry.

[0057] The specific embodiments of the present application will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0058] As Figs. 1 to 4The artificial intelligent steel plate for inducing natural retraction of herniated intervertebral disc, comprising a steel plate body 1, which is characterized in that: a plurality of deformation adjusting blocks 2 are distributed on the steel plate body 1 (at least one deformation adjusting block 2 can be distributed), and a deformation control assembly is embedded in each deformation adjusting block 2, so that the deformation adjusting block 2 can deform according to needs, so that the steel plate body 1 also deforms, thereby accelerating the retraction control of the herniated intervertebral disc. Specifically, the deformation control assembly comprises a wireless module 3 installed in the deformation adjusting block 2, which can adapt to the magnetic resonance wireless charging technology to realize non-contact energy supply to meet the long-term use requirement. Meanwhile, the wireless module 3 is connected with a central processing unit 4, and the central processing unit 4 is further connected with a sensor module 5 and a factor release module 6 respectively.

[0059] During implementation, the factor release module 6 is composed of a shell 7, a piezoelectric ceramic 8 and a factor solution reservoir 9. In consideration of the convenience of control, the factor solution reservoir 9 is provided with a factor release micropore 10 for precisely controlling the flow, the piezoelectric ceramic 8 is attached between the solution reservoir 9 and the shell 7, and the piezoelectric ceramic 8 is electrically connected with the central processing unit 4. Furthermore, the shell 7 and the deformation adjusting block 2 are both provided with a through hole 11 in communication with the factor release micropore 10. In this way, the factor solution from the human body can be sensed, and the release of the factor solution can be met when needed. That is to say, the sensor module 5 can detect the change of the factor concentration in the factor release module 6 through the transmission of the central processing unit 4. When the preset value is reached, the sensor module 5 feeds back to the central processing unit 4 to control the load voltage of the piezoelectric ceramic 8, so that the piezoelectric ceramic 8 can be deformed slightly to extrude the factor solution in the factor solution reservoir 9, thereby regulating the actual release of the factor solution through the release micropore 10 to promote the retraction of the herniated intervertebral disc. The factor solution involved in the present application can be pre-stored β-CTx factor (β-collagen), or other components, and the currently marketed products can be selected, which are not the contents to be protected by the present application and will not be described here.

[0060] In combination with a preferred embodiment of the present application, the steel plate body 1 is provided with an installation inlay, and the upper and lower ends of the installation inlay are both provided with a storage cavity, and the deformation adjusting block 2 is installed in the storage cavity. In consideration of the stability of combination, the deformation adjusting block 2 and the installation inlay can be mutually adhered through a medical adhesive, or combined in an interference fit manner to avoid loosening. During implementation, the two deformation adjusting blocks 2 can be arranged back to back. In this way, the steel plate body 1 can be deformed more appropriately to meet the retraction requirement of the herniated intervertebral disc.

[0061] Further, the deformation adjusting block 2 is provided with an embedded groove, and the wireless module 3 is installed in the embedded groove, and the wireless module 3 is an NFC coil. Meanwhile, the number of turns of the NFC coil is 5 to 10 turns. In this way, the corresponding components in the deformation adjusting block 2 can be powered by using the wireless charging technology. During daily use, the NFC coil can be continuously powered by the wearable external equipment such as a neck support and a waistband. The existing wearable external equipment such as a neck support and a waistband can be additionally provided with a wireless charging module for use, thereby facilitating adaptation and modification. The wearable external equipment that can be powered is a commonly used device in the field, and will not be described here. Moreover, the sensor module 5 is a carbon nanotube sensor, and the sensing electrode area of the carbon nanotube sensor is 2 square millimeters. In this way, the sensor can effectively sense the change in the concentration of the factor solution in the factor solution reservoir 9 during use, and can timely feedback to the piezoelectric ceramic 8 for corresponding micro-deformation operation.

[0062] In combination with the actual implementation, the piezoelectric ceramic 8 is a rectangular sheet structure, and the contact area with the side surface of the factor solution reservoir 9 is 3 to 20 square millimeters. In this way, effective micro-deformation can be achieved, so that the factor solution reservoir 9 is appropriately pressed and stressed to meet the release of the factor solution therein. During implementation, the factor solution reservoir 9 is a cylindrical structure, which is connected to the inner side of the shell 7 by ultrasonic welding. Meanwhile, the release channels with an inner diameter of 0.2 millimeters are distributed between the factor release micro-holes 10 and the various through holes 11, thereby facilitating the flow of the factor solution. Moreover, the hole diameter of the factor release micro-hole 10 is 0.1 millimeter, which can meet the stable and accurate release of the factor solution.

[0063] Further, the central processing unit 4 is connected to the sensor module 5 and the factor release module 6 through a flexible circuit board with a thickness of 0.2 millimeters. Meanwhile, the flexible circuit board is provided with anti-interference signal transmission lines and high-efficiency power supply lines. In this way, stable signal transmission and energy supply can be met. During preparation, the flexible circuit board is made of polyimide material, which has good flexibility and electrical properties.

[0064] Meanwhile, in order to significantly reduce the human immune rejection reaction, a collagen coating can be provided on the outside of the deformation adjusting block 2, and the thickness of the collagen coating is 0.02 to 0.1 millimeter. Specifically, it is preferably 0.05 millimeter, and the spraying process can be used for uniform attachment during manufacturing.

[0065] Furthermore, in consideration of the convenience of implementation, the central processing unit 4 is an STM32F407 processor or an MSP430FR5969 processor. In this way, it has high-speed data processing capability and low-power consumption characteristics. Of course, other types of small-size processors can also be preferred. The "steel plate" described in the utility model is commonly used in the industry, and is not limited to the material. In actual use, titanium alloy steel plates and the like can also be used, and will not be described here.

[0066] The working principle of the utility model is as follows:

[0067] According to the need of retraction, the appropriate factor solution is selected and stored in the factor solution storage 9, and the human body is placed. Subsequently, when the sensor sensing module 3 senses that the concentration of a certain factor in the local body fluid of the operation is beneficial to enhancing the fiber structure of the extracellular matrix, the signal is sent to the central processor 4. Then, the central processor 4 sends an instruction to change the voltage of the piezoelectric ceramic 8 to make it deform. Thus, the factor solution storage 9 is extruded, and the factor solution in it is released through the release micro-hole 10.

[0068] For some special use requirements, the central processor 4 can sense the concentration of the factor solution, and the piezoelectric ceramic 8 is deformed when the concentration reaches the optimal range.

[0069] It should be noted that the factor solution involved in the utility model is only a medium for realizing the natural retraction of the herniated intervertebral disc, and its components are not the object of protection of the utility model. At the same time, the above working principle is only used to explain the actual working process of the utility model, and is not an emphasis on the actual treatment scheme of the herniated intervertebral disc, which is not the object of protection of the application and does not involve disease treatment.

[0070] Through the above text description and combined with the drawings, it can be seen that after adopting the utility model, the following advantages are obtained:

[0071] 1. It can meet the intelligent adjustment, rely on the mutual cooperation of the piezoelectric ceramic and the factor solution storage, realize the effective deformation of the steel plate body, and guide the natural retraction of the herniated intervertebral disc.

[0072] 2. Wireless charging technology is adopted to reduce the volume of the steel plate, and the NFC coil can be stably and continuously powered by the wearable external power supply equipment such as a neck support and a waist support.

[0073] 3. The central processor can be used for effective factor parameter adjustment to meet the individual use needs of different patients.

[0074] 4. The existing steel plate body can be adaptively modified, and the implementation cost is low.

[0075] In addition, the indicating direction or position relationship described in the utility model is based on the direction or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or structure must have a specific direction or be operated in a specific direction, so it cannot be understood as a limitation of the utility model.

[0076] The above merely is preferred implementation manner of the present application, and is not used for limiting the present application, it should be pointed out, for ordinary skilled person in the technical field, on the premise of not departing from the technical principle of the present application, can also make several improvements and variations, these improvements and variations also should be regarded as the protection scope of the present application.
