Abstract
Description
Technical field:
[0001] The present invention relates to the technical field of mechanical correction without human body intervention, and in particular to a numerically controlled three-dimensional spine correction instrument and a method for setting key parameters thereof. Background technology:
[0002] After years of research and clinical experience, the inventor of this case has concluded that although the temporary names of cervical spondylosis, lumbar disc herniation, thoracic and lumbar posterior joint disorder, secondary lumbar spinal stenosis, lumbar muscle strain, lumbar three transverse process syndrome and various injuries related to the spine have different clinical manifestations, their causes, pathologies and treatment principles are basically the same; the existing temporary names cannot fully indicate the exact location and nature of the lesions, so the inventor, based on the principles of disease naming, first proposed the concept of spinal intervertebral disease. Spinal intervertebral disease is a general term for a series of diseases caused by adverse mechanical behaviors such as excessive movement or overload of the spine, and three-dimensional changes (imbalances) in the relative position of the vertebrae caused by wind, cold and dampness, combined with injuries to the intervertebral tendons. Diseases that occur in a certain intervertebral space are called certain intervertebral diseases, such as cervical 4 / 5 intervertebral disease, thoracic 7 / 8 intervertebral disease, lumbar 5 / sacral 1 intervertebral disease, etc. The concept of intervertebral disease of the spine clarifies the site of the lesion - a certain intervertebral space of the spine, clarifies the cause of the disease - injury, clarifies the pathological changes - bone dislocation and tendon dislocation, and clarifies the treatment principle - to set things right and return to the natural state.
[0003] At present, the treatment of spinal intervertebral disease mainly includes three categories:
[0004] One is a surgical method aimed at destroying the diseased intervertebral disc. It includes open surgery and minimally invasive surgery. It is mainly suitable for patients who have not responded to various non-surgical treatments. It is the final choice and accounts for a very small number of the patient population.
[0005] The second is to adopt symptomatic palliative therapy: including rest, medicine, acupuncture, physical therapy, traction, etc., and ultimately rely on self-repair, adaptation, and compensation. It is mainly suitable for patients with mild symptoms.
[0006] The third is the causal correction treatment method to correct the relative position changes between the diseased vertebrae, relieve the tension between the intervertebral soft tissues, and make them tend to a natural state: including Chinese medicine massage bone setting, European Orthopaedic Medicine, American Chiropractic and other mechanical methods and three-dimensional spinal correction therapy.
[0007] Among them, the three-dimensional spinal correction therapy is the first invention of the inventor of this case. It refers to the use of information technology to control automated machinery (three-dimensional spinal correction instrument), simulate the various key movements of traditional Chinese medicine spinal correction techniques (the trick to the movement is to exert force instantly), and simultaneously apply precise and quantified three-dimensional movements to the diseased intervertebral space, so as to correct the dislocation of the tendons and bones between the spine, correct the intervertebral position, and achieve the purpose of harmonious intervertebral structure to treat spinal intervertebral diseases. The three-dimensional spinal correction instrument is a key automated mechanized equipment in the three-dimensional spinal correction therapy. The inventor has developed and continuously improved the three-dimensional spinal correction instrument and applied for patent protection. The relevant existing patent documents are as follows:
[0008] Chinese patent numbers: ZL97182091.0; ZL200880129766.2; ZL201110300155.3; ZL201911231855.4.
[0009] The three-dimensional spine correction device developed by the inventor has achieved satisfactory results after clinical application. During this period, the inventor cooperated with a professor of mechanics at Tsinghua University to conduct real-time measurement of the therapeutic effect of the three-dimensional spine correction device, and the conclusion was that it was safe and effective.
[0010] However, after many years of clinical application by the inventor and his peers, especially with the increase in the number of patients treated and the increasing complexity of patients' conditions, it was found that the three-dimensional chiropractic instrument still has some deep-seated technical problems that need to be solved urgently. This is mainly reflected in two aspects. First, the three-dimensional structure is deficient in spatial movement. The head and chest plate in the existing three-dimensional chiropractic instrument can only move horizontally along the longitudinal axis, and the hip and leg plates rotate around the transverse axis to form an angle with the head and chest plate. The hip and leg plates rotate around the longitudinal axis (i.e., the rotation angle), and the hip plate rotates (i.e., the torsion angle). These are all the spatial movements of the existing three-dimensional chiropractic instrument. The combination of these movements has a good correction effect on most intervertebral lesions in the spine. However, in actual applications, it was found that the correction effect of some intervertebral lesions is not ideal, such as spondylolisthesis (such as Figure 13 As shown in the figure, another example is abnormal spinal curvature in children, especially kyphosis. After in-depth analysis and multiple clinical experiments, it was found that the main reason for the unsatisfactory correction of the above-mentioned intervertebral diseases is the lack of coordination of the anterior and posterior top movements of the vertebrae with anterior and posterior displacement; secondly, the fixation of patients is still manual, which is time-consuming and labor-intensive and cannot be accurately quantified; thirdly, the key parameters of the three-dimensional spinal correction instrument were previously only given a safety range, and most of them were set by doctors within the safety range based on clinical experience. The key parameter settings were quite different, which led to large differences in the correction effect. Therefore, it is necessary to set the key parameters reasonably, and at the same time, the parameters can be adjusted adaptively according to individual differences.
[0011] In summary, it is necessary to further optimize and improve on the basis of the existing three-dimensional chiropractic instrument, with a view to perfecting the three-dimensional space movement, realizing automatic quantification and fixation, and making the key parameter settings more reasonable. The whole machine integrates mechanization, informatization, digitization and automation, more accurately reflects various key movements of traditional Chinese medicine chiropractic techniques, uses techniques to exert force instantly (fast), and instantaneously applies the three-dimensional six-degree-of-freedom movements that are difficult to quantify by manual chiropractic to the diseased intervertebral space, prompting the intervertebral structure to tend to the natural state.
[0012] It should be noted that the above content belongs to the technical cognitive scope of the inventor and does not necessarily constitute the prior art. Summary of the Invention:

Specific implementation manner:
[0061] In order to more clearly illustrate the overall concept of the present invention, the following will be described in detail by way of examples in conjunction with the specification drawings.
[0062] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.
[0063] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.
[0064] In addition, terms such as "x-axis", "y-axis", "z-axis", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the position of the indicated technical features.
[0065] In the present invention, unless otherwise clearly defined and limited, terms such as "provided with", "set", "connected", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection; it may be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0066] Such as Figures 1-12As shown in the figure, a numerically controlled three-dimensional spinal adjuster includes a frame 1. Along the y-axis direction on the frame 1, a head and chest plate 2 and a hip and leg plate 3 are successively arranged. A hip plate 4 is rotatably arranged on the hip and leg plate 3. The head and chest plate 2 is slidably arranged along the y-axis on a slide rail seat 5. On the frame 1, a bow-shaped bracket 6 that rotates around the x-axis is provided. On the bow-shaped bracket 6, a hip and leg plate 3 that rotates around the y-axis is provided. An impact driving mechanism 7 for driving the head and chest plate 2 to slide impulsively along the y-axis is provided on the slide rail seat 5. The slide rail seat 5 is rotatably arranged on the frame 1, and a fast top driving mechanism 8 for driving the side of the head and chest plate 2 close to the hip and leg plate 3 to quickly lift and lower along the z-axis direction is provided between the frame 1 and the slide rail seat 5. An angle adjustment mechanism 9 for driving the bow-shaped bracket 6 to rotate around the x-axis is provided between the frame 1 and the bow-shaped bracket 6. A linkage driving mechanism 10 is provided between the bow-shaped bracket 6 and the hip and leg plate 3. The linkage driving mechanism 10 respectively drives the hip and leg plate 3 to rotate around the y-axis and drives the hip plate 4 to twist. The impact along the y-axis and the fast top action along the z-axis of the head and chest plate 2, the rotation action of the hip and leg plate 3 around the y-axis, and the twisting action of the hip plate 4 are required to be synchronously completed within 0.25 seconds. By adding the ability of the side of the head and chest plate 2 close to the hip and leg plate 3 to quickly lift and lower along the z-axis direction, the lack of spatial movement of the previous three-dimensional spinal adjuster (bed) is made up for, and it can more accurately simulate various key actions of traditional Chinese medicine spinal adjustment techniques. The precisely quantified three-dimensional six-degree-of-freedom actions are simultaneously applied to the diseased intervertebral space, promoting the intervertebral structure to tend to the natural state, and the correction effect is significantly improved. Especially for the abnormal anterior and posterior convex curvature of the spine in the case of spondylolisthesis, the correction effect is more prominent. In addition, except for angle adjustment, the completion time of other actions is limited and must be synchronously completed within 0.25 seconds, and generally about 0.2 seconds in actual operation. This technical feature fully reflects the core difference from the traction bed: the international and domestic standards of existing traction beds are to control the magnitude of the traction force and the traction time, and the traction force generally is not allowed to exceed the body weight; the reason is that there are stretch receptors in human muscle fibers, and when the stretch receptors are stretched, they will contract and resist. When the traction force exceeds its isometric traction, the muscle fibers will be damaged. The impact and tremor used in this solution require rapid impact force, and what it controls is the impact distance. The impact distance is controlled within the elastic limit of the spinal soft tissue and will not be damaged. The faster the speed, the lighter the pain and the smaller the damage (almost no damage). Since the patient is a living body, according to the fact that the intensity of pain sensation of the human body is related to the action time (time-intensity curve, SD curve), the shorter the time, the less pain. By controlling the action completion time, the impact and tremor action is completed before there is time to react. The impact force in this solution is several times greater than the usual traction force. Due to the existence of the limit blocking member, it is ensured that the extension of the intervertebral space being impacted and tremored is within its elastic limit. The impulse generated by this impact force will not all act on the human body, and the impulse after reaching the treatment amount is dispersed by the blocking member, so it will not cause harm to people.
[0067] The slide rail seat 5 is rotatably arranged at the upper end of the frame 1 through the rotating shaft A11 and the bearing pedestal A12. The rotating shaft A11 and the bearing pedestal A12 are arranged along the x-axis direction. The quick jacking driving mechanism 8 includes a servo electric cylinder A801 rotatably arranged on the frame 1. A hinge seat A802 is arranged at the lower end of one side of the slide rail seat 5. The servo electric cylinder A801 is rotatably connected with the hinge seat A802 through a piston rod joint A803. The servo electric cylinder A801 drives the slide rail seat 5 and the head and chest plate 2 thereon to quickly jack up and down. By adding a rotating motion to the slide rail seat 5 and the head and chest plate 2 thereon, and driving the head and chest plate 2 to rotate through the quick jacking driving mechanism 8, when the head and chest plate 2 rotates, the side close to the hip and leg plate 3 can quickly move up and down along the z-axis direction, thereby realizing the quick jacking action. The driving form mainly uses a servo electric cylinder. The servo electric cylinder (abbreviation: servo cylinder) is an integrated product integrating a servo motor and a lead screw. Its running speed is 0.1 - 2 m / s. At the same time, it adopts closed-loop servo control, has the advantages of adjustable stroke and high running accuracy, and also has a self-locking function. When the jacking action is not required, the head and chest plate 2 can be kept in a horizontal posture. In this technical solution, the maximum stroke is 50 mm and it is required to be completed within 0.25 seconds. Therefore, the running speed is required to be greater than 0.2 m / s. Obviously, the prior art can meet the design requirements. In addition, the maximum thrust of the JWMC product system can reach 35 tons and the maximum speed can reach 2 m / s. In actual application, the head and chest plate 2 is adjusted to a horizontal state through the servo electric cylinder A801, and it can run up or down when the quick jacking action is required.
[0068] An automatic quantitative fixing mechanism 13 is respectively provided on the cephalothoracic plate 2 and the gluteal plate 4. The automatic quantitative fixing mechanism 13 includes an electric tightening device 1301, a buckle 1302 and a pressure sensor 1303. A webbing 1304 is wound around the electric tightening device 1301. A locking tongue 1305 cooperating with the buckle 1302 is provided at the front end of the webbing 1304. Pressure slides 1306 are respectively provided on the cephalothoracic plate 2 and the gluteal plate 4. A pulley support 1307 is slidably provided on the pressure slide 1306. A pulley 1308 is provided at the front end of the pulley support 1307, and the rear end acts on the pressure sensor 1303. The webbing 1304 is arranged on the pulley 1308. In the past, the fixation of the key parts (waist and buttocks) of patients was completed by manual operation of medical staff, which led to a large difference in the tightness of human fixation. And the fixation of the key part directly affects the correction effect. If the fixation is too loose, the correction action will not be in place, and the correction effect will be poor. If the fixation is too tight, not only will the patient feel uncomfortable, but it will also affect the correction effect. By designing the automatic quantitative fixing mechanism 13, automatic fixation can be achieved. Through the cooperation of the pulley 1308 and the pressure sensor 1303, not only can the webbing 1304 be smoothly reversed and retracted, but also the pressure received by the pulley 1308 can be transmitted to the pressure sensor 1303. The tightness of the webbing is quantitatively detected by the pressure sensor 1303, realizing the quantification of the fixation tightness, effectively reducing the possibility of human intervention, ensuring that the fixation tightness of the patient is more reasonable, and thus helping to improve the correction effect.
[0069] A slide rail 14 is provided on the upper end of the slide rail seat 5 along the y-axis. A slider 15 is provided on the slide rail 14. The cephalothoracic plate 2 is fixed on the slider 15.
