Description

Technical Field

[0001] The invention relates to a steel plate device for treating intervertebral disc herniation, and in particular to an intelligent steel plate for artificially inducing natural retraction of a herniated intervertebral disc, which belongs to one of the medical devices. Background Art

[0002] In the field of orthopedics, cervical and lumbar disc herniation is an extremely common and frequent disease. For a long time, a variety of clinical treatment methods have been developed for this type of spinal degenerative disease, using instruments such as steel plates as surgical or recovery devices. At the same time, it involves artificial pedicle screw implantation and internal fixation, robot navigation pedicle screw implantation and internal fixation to stabilize the spine; discectomy and fusion is to remove the diseased disc and then perform intervertebral fusion.

[0003] In recent years, with the in-depth advancement of clinical research and the continuous innovation of imaging technology, people have surprisingly found that the herniated disc retracts naturally during conservative treatment. Although the incidence of this phenomenon is low, this discovery breaks the traditional cognition and proves that the herniated disc is similar to bone tissue and has the property of being "repairable".

[0004] In 2021, it was revealed that after endoscopic minimally invasive cervical double-door laminoplasty, the herniated intervertebral disc can undergo extensive and efficient natural absorption. In order to distinguish it from the natural retraction phenomenon in conventional conservative treatment, the natural retraction of the herniated intervertebral disc after this operation is named "artificially induced natural retraction of herniated intervertebral disc" technology, abbreviated as "artificial induction, disc preservation and restoration". The core of this technology is that no "direct" intervention is performed on the herniated intervertebral disc during the operation, such as injecting drugs into the herniated intervertebral disc, inserting laser optical fiber for ablation, or performing herniated nucleus pulposus resection. Instead, the vertebral lamina is symmetrically decompressed to move the spinous process ligament complex posteriorly, and then fixed with a micro-titanium steel plate to expand the spinal canal and improve the local ischemic and hypoxic microenvironment of the spinal canal caused by the herniated disc, thereby promoting the natural retraction of the herniated intervertebral disc.

[0005] Inspired by the success of artificially induced natural retraction of cervical disc herniation, major breakthroughs have also been made in the field of lumbar disc herniation, and the "cohesive" symmetrical decompression of the lumbar spine to artificially induce the natural retraction of the herniated disc has also been gradually applied in clinical practice. Research data show that after the "cohesive" symmetrical decompression of the lumbar spine to artificially induce the natural retraction of the herniated disc, up to 94% of the herniated lumbar discs can retract to varying degrees. At the same time, AI technology has also been successfully applied in assisting the measurement of the volume of herniated discs, which is of key value for accurately evaluating the changes in the volume of herniated discs and tracking the treatment effects.

[0006] Previous clinical studies have confirmed that multiple factors are released during the healing process of bilateral lamina decompression and trough bone in minimally invasive cervical double-door laminoplasty under endoscopy. These factors are very likely to participate in the matrix metabolism of the herniated intervertebral disc, creating favorable conditions for the natural retraction of the herniated intervertebral disc.

[0007] As we all know, the intervertebral disc is a structure located between the vertebrae of the human body, which is mainly composed of the following parts:

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

[0009] 2. The nucleus pulposus is a gel-like substance rich in water and proteoglycan, which has the function of absorbing shock and maintaining the height and elasticity of the intervertebral disc.

[0010] 3. The cartilage endplates are located above and below the intervertebral disc. They are thin layers of hyaline cartilage connected to the vertebrae, providing nutrition and dispersing pressure.

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

[0012] 1. Annular fibrosus cells, the main type of which is fibroblast-like cells, can synthesize and maintain the collagen and matrix of the annulus fibrosus.

[0013] 2. Nucleus pulposus cells include chondrocytes, 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 and is 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, while the nucleus pulposus is mainly composed of type II collagen, which maintains elasticity.

[0017] 2. The main components of proteoglycans, such as aggrecan, attract and retain water, maintaining the gel-like structure and compression resistance of the nucleus pulposus.

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

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

[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 the 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 generation; fibroblast growth factor (FGF) promotes cell proliferation and matrix synthesis and is involved in the repair and regeneration of the intervertebral disc; 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 intervertebral disc repair process.

[0021] 2. Cytokines play a key role in intervertebral disc degeneration and inflammatory responses. These include interleukin-1 (IL-1), which 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), which induces inflammatory responses, promotes matrix degradation, and accelerates intervertebral disc degeneration; interleukin-6 (IL-6), which is involved in inflammatory responses and matrix degradation and is highly expressed in degenerated intervertebral discs; interleukin-10 (IL-10), which has an anti-inflammatory effect, inhibits matrix degradation, and protects the intervertebral disc matrix.

[0022] 3. Matrix degrading enzymes are involved in the degradation of the intervertebral disc matrix, and their imbalanced activity can lead to intervertebral disc degeneration. These include matrix metalloproteinases (MMPs), such as 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, which specifically degrade proteoglycans (such as aggrecan) and play an important role in intervertebral disc degeneration.

[0023] 4. Matrix synthesis promoting factors These factors promote the synthesis of matrix components and maintain the health of the intervertebral disc. For example, Sox9 can regulate the gene expression of type II collagen and aggrecan, and promote the differentiation of chondrocyte-like cells and matrix synthesis; hypoxia-inducible factor-1α (HIF-1α) promotes cell survival and matrix synthesis in a hypoxic environment and maintains the metabolism and function of nucleus pulposus cells. Other regulatory factors such as NF-κB (nuclear factor κB), such as regulating the expression of inflammatory factors and matrix degrading enzymes, 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 the extracellular matrix of the intervertebral disc is jointly regulated by multiple factors. The balance of these factors is crucial for the health of the intervertebral disc, and imbalance may lead to intervertebral disc degeneration.

[0025] Previous studies have shown that during the process of disc degeneration, the protruding disc that occupies the spinal canal space will cause local compression of the dura mater sac, and many metalloproteinases such as MMP-3 and Col1a show mechanical parameter-dependent expression, which will have the effect of degrading the extracellular matrix. After the induction surgery of minimally invasive cervical double-door laminoplasty under endoscopy, the mechanically dependent cell pathway is blocked due to the reduction of local pressure in the spinal canal, forming a protection for the extracellular matrix. β-Collagen special sequence (β-CTx) is a C-terminal peptide decomposition fragment of type I collagen, which contains an octapeptide composed of glutamic acid-lysine-alanine-histidine-β-aspartic acid-glycine-glycine-arginine (EK-ADH-β-GGR). At present, some studies believe that it is a reliable biochemical indicator for evaluating bone resorption. When the bone turnover rate in the human body increases and bone resorption increases significantly, the degradation of type I collagen also increases, and the content of β-CTx in the blood as a decomposition fragment also increases accordingly. The bone healing of the human body generally goes through four stages over time: "hematoma organization stage - callus formation stage - bone healing stage - bone plasticity stage". The bilateral lamina decompression grooves formed by endoscopic minimally invasive cervical canal expansion and shaping surgery may release a large amount of β-CTx about one week after surgery, and its concentration can be detected in the peripheral blood and increased significantly. This high concentration of β-CTx exists and participates in the metabolism of the extracellular matrix of the herniated intervertebral disc. Since CTx is a degradation product of mature collagen fibers under catalytic conditions such as metalloproteinases (MMPs), it reflects the activity of bone metabolic enzymes. At this time, the staged increase represents the overall level of bone metabolism. Corresponding to the long-term stage, the expression level of bone metabolic synthetic enzymes such as synthases is also higher, the level of collagen fibers and glycosaminoglycans synthesized by the nucleus pulposus cells in the intervertebral disc increases, and the fiber structure of the extravertebral matrix is ​​enhanced, thereby ensuring that the intervertebral disc structure maintains the height and strength of the retracted intervertebral disc at the preoperative level after experiencing the process of "degeneration-protrusion-retraction". Previous studies have also found that nucleus pulposus cells can secrete enzymes in a mechanically responsive manner to regulate extracellular matrix components, and these enzymes can induce natural retraction of herniated intervertebral discs.

[0026] Herniated intervertebral discs are mostly degenerative nucleus pulposus tissues, which are composed of nucleus pulposus cells and extracellular matrix. The extracellular matrix is ​​a mesh structure composed of type II collagen / proteoglycan, in which glycosaminoglycan chains containing SO4- absorb water to form the mechanical properties and structural basis of the intervertebral disc. The compression force (2MPa) stimulates the nucleus pulposus cells for 4 hours and then withdraws it for 20 hours. At this time, iNOS expression increases. Similarly, in chondrocytes, the expression activity of metalloenzyme genes such as MMP-3, MMP-13, ADAMTS-4 and ADAMTS-5 is significantly increased after the tensile physical and mechanical stimulation (7.5%, 1Hz) is maintained and then withdrawn.

[0027] However, the steel plates currently used to fix the spinous process ligament complex in minimally invasive cervical laminoplasty under endoscopy are just ordinary micro titanium alloy steel plates. Although this type of steel plate can provide support and fixation, and help the bony 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 designers have actively carried out research and innovation in order to create an intelligent steel plate that can artificially induce the natural retraction of the protruding intervertebral disc, making it more valuable for industrial use. Summary of the invention

[0056] 11 Through Hole DETAILED DESCRIPTION

[0057] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0058] like Figures 1 to 4The intelligent steel plate for artificially induced protruding intervertebral disc to retract naturally includes a steel plate body 1, which is different in that: a plurality of deformation adjustment blocks 2 (at least one deformation adjustment block 2) are distributed on the steel plate body 1, and the deformation adjustment block 2 is embedded with a deformation control component, so that the deformation adjustment block 2 itself can be deformed as needed, so that the steel plate body 1 is also deformed, and then the retraction control of the protruding intervertebral disc is accelerated. Specifically, the deformation control component includes a wireless module 3 installed in the deformation adjustment block 2, which can be adapted to the magnetic resonance wireless charging technology to realize non-contact energy supply to meet the needs of long-term use. At the same time, the wireless module 3 is connected to the central processing unit 4, and the central processing unit 4 is also connected to the sensor module 5 and the factor release module 6 respectively.

[0059] During the implementation, the factor release module 6 is composed of a housing 7, a piezoelectric ceramic 8, and a factor solution reservoir 9. Considering the convenience of control, the factor solution reservoir 9 is provided with a factor release micropore 10 for accurately controlling the flow rate, and the piezoelectric ceramic 8 is attached between the solution reservoir 9 and the housing 7, and the piezoelectric ceramic 8 is electrically connected to the central processor 4. Furthermore, the housing 7 and the deformation adjustment block 2 are both provided with a through hole 11 that is connected to the factor release micropore 10. In this way, the factor solution from the human body can be sensed, and when necessary, the release of the factor solution can be satisfied. In other words, the sensor module 5 can detect the change in the factor concentration from the inside of the factor release module 6 through the transmission of the central processor 4. When the preset value is reached, the sensor module 5 feeds back to the central processor 4, allowing it to control the load voltage of the piezoelectric ceramic 8, so that it can be slightly deformed, thereby squeezing the factor solution in the factor solution reservoir 9, and regulating the actual release of the factor solution through the release micropore 10, thereby promoting the retraction of the protruding intervertebral disc. The factor solution involved in the present invention may be pre-stored β-CTx factor (β-collagen) or other components. Current commercially available products may be selected. They are not the content to be protected by the present invention and will not be described in detail here.

[0060] In combination with a preferred embodiment of the present invention, the steel plate body 1 is provided with mounting strips, and storage cavities are provided at both the upper and lower ends of the mounting strips, and deformation adjustment blocks 2 are installed in the storage cavities. Considering the stability of the combination, the deformation adjustment blocks 2 and the mounting strips can be adhered to each other by medical adhesives; or, they can be combined in an interference fit to avoid loosening. During implementation, the two deformation adjustment blocks 2 can be arranged back to back. In this way, the steel plate body 1 can be subjected to more appropriate deformation adjustment to meet the retraction requirements of the protruding intervertebral disc.

[0061] Further, there are embedded grooves in the deformation adjustment block 2, and the wireless module 3 is installed in the embedded grooves, and the wireless module 3 is an NFC coil. At the same time, the number of turns of the NFC coil is 5 to 10 turns. In this way, it is convenient to use wireless charging technology to supply energy to the corresponding components in the deformation adjustment block 2. During daily use, the NFC coil can be continuously powered by powered external wearable devices such as neck braces and waist belts. Wireless charging modules can be added to existing external wearable devices such as neck braces and waist belts for use, which is convenient for adaptation and modification. Powered external wearables are commonly used in this field and will not be repeated here. In addition, the sensor module 5 used 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 changes in concentration in the factor solution reservoir 9 during use, and can promptly feedback to the piezoelectric ceramic 8 for corresponding micro-deformation operations.

[0062] In combination with the actual implementation, the piezoelectric ceramic 8 used is a rectangular thin sheet structure, and the contact area with the side 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 squeezed and forced to meet the release of the factor solution therein. During the implementation, the factor solution reservoir 9 is a cylindrical structure, which is connected to the inner side of the shell 7 by ultrasonic welding. At the same time, a release channel with an inner diameter of 0.2 mm is distributed between the factor release micropores 10 and each through hole 11 to facilitate the flow of the factor solution. In addition, the hole diameter of the factor release micropore 10 is 0.1 mm, which can meet the stable and precise release of the factor solution.

[0063] Looking further, the central processor 4 used in the present invention is connected to the sensor module 5 and the factor release module 6 through a flexible circuit board with a thickness of 0.2 mm. At the same time, the flexible circuit board is provided with anti-interference signal transmission lines and efficient power supply lines. Thus, stable signal transmission and energy supply can be met. During the preparation, the flexible circuit board is made of polyimide material, which has good flexibility and electrical properties.

[0064] At the same time, in order to significantly reduce the human immune rejection reaction, a collagen coating can be provided on the outer side of the deformation adjustment block 2, and the thickness of the collagen coating is 0.02 to 0.1 mm. Specifically, it is preferably 0.05 mm, and can be evenly attached by spraying process during manufacturing.

[0065] Furthermore, considering the convenience of implementation, the central processor 4 is an STM32F407 processor or an MSP430FR5969 processor. As a result, it has high-speed data processing capabilities and low power consumption characteristics. Of course, other types of small-volume processors can also be preferred. The "steel plate" described in the present invention is a common name in the industry, and the material is not limited. In actual use, titanium alloy steel plates can also be used, which will not be repeated here.

[0066] The working principle of the present invention is as follows:

[0067] According to the need for retraction, a suitable factor solution is selected and stored in the factor solution reservoir 9 for human body implantation. Subsequently, when the sensor module 3 senses the concentration change of a certain factor in the local body fluid of the operation that is beneficial to enhancing the fiber structure of the exo-matrix, the signal is sent to the central processor 4. After that, the central processor 4 issues an instruction to change the voltage of the piezoelectric ceramic 8 to deform it. As a result, the factor solution reservoir 9 is squeezed, and the factor solution therein is released through the release micropores 10.

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

[0069] It should be noted that the factor solution involved in the present invention is only a medium for achieving the natural retraction of the herniated intervertebral disc, and its components are not the objects protected by the present invention. At the same time, the above working principle is only used to explain the actual working process of the present invention, and does not emphasize the actual treatment plan for the herniated intervertebral disc. It is not the object protected by this application and does not involve disease treatment.

[0070] It can be seen from the above textual description and the accompanying drawings that the present invention has the following advantages:

[0071] 1. It can meet the requirements of intelligent adjustment, relying on the cooperation of piezoelectric ceramics and factor solution reservoirs to achieve effective deformation of the steel plate body and guide the natural retraction of the protruding intervertebral disc.

[0072] 2. Wireless charging technology is used to reduce the volume of the steel plate, and the NFC coil can be stably and continuously powered through powered external wearable devices such as neck braces and waist belts.

[0073] 3. The central processing unit can be used to make effective factor parameter adjustments to meet the personalized needs of different patients.

[0074] 4. The existing steel plate body can be adaptively modified with low implementation cost.

[0075] In addition, the indicated orientations or positional relationships described in the present invention are all based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or structure referred to must have a specific orientation or be operated with a specific orientation structure. Therefore, they cannot be understood as limitations on the present invention.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
