Description

Technical Field

[0001] The present invention relates to a medical device for the treatment of scoliosis, and particularly to a magnetic ring for the treatment of scoliosis. Background Art

[0002] Scoliosis is a common skeletal deformity disease. Please refer to Figure 1 the scoliosis symptoms shown. Its main manifestations are that one or several segments of the spine bend laterally, or there is a spinal deformity accompanied by vertebral rotation, making the back present a C-shaped or S-shaped curve instead of a normal straight line. This abnormal bending phenomenon may occur in any part of the spine, but is most common in the thoracic and lumbar vertebrae.

[0003] The clinical diagnosis of scoliosis is generally achieved by measuring the Cobb angle. On the full-length lateral X-ray film of the spine in the standing position, the intersection angle between the perpendicular line of the upper edge of the upper end vertebra and the perpendicular line of the lower edge of the lower end vertebra is the Cobb angle. If the Cobb angle is greater than 10°, scoliosis can be diagnosed. According to the size of the Cobb angle, the severity of scoliosis can be divided into mild scoliosis, moderate scoliosis, and severe scoliosis; a Cobb angle of 10° - 20° belongs to mild scoliosis. Appropriate exercise can improve mild postural abnormalities, but the progress of the spine still needs to be regularly detected; a Cobb angle of 21° - 40° belongs to moderate scoliosis. For the treatment of scoliosis with a Cobb angle of 21° - 29°, exercise should be maintained. If the scoliosis progresses rapidly, such as increasing by more than 5° after half a year, an orthotic brace needs to be worn. For scoliosis with a Cobb angle of 30° - 40°, an orthotic brace should be directly used for correction; a Cobb angle greater than 40° belongs to severe scoliosis. After comprehensive evaluation by a doctor according to the shape and degree of scoliosis, surgical correction treatment should be directly adopted.

[0004] Generally speaking, the methods for treating scoliosis mainly include exercise correction, brace treatment, and surgical treatment. Among them, exercise correction and brace treatment are suitable for early and mild conditions, especially for children in the growth period, which can effectively prevent the progression of the curvature and improve posture. Surgical treatment is suitable for patients with severe conditions that cannot be corrected by conservative treatment. The purpose is to correct the spinal deformity, prevent further deterioration, and restore the function of the spine as much as possible.

[0005] Surgical correction treatment of the spine is usually carried out for scoliosis angles greater than 45° to 50°, or for cases that cause obvious functional impairment and pain. Currently, the generally adopted surgery is spinal fusion. By using instruments such as metal rods, hooks, and screws, the affected vertebrae are fixed together, and bone graft materials are implanted to promote the fusion between adjacent vertebrae. Over time, these vertebrae will grow into a solid whole. This method will cause the following defects: 1. Adjacent segment disease: The unfused adjacent vertebrae may bear greater pressure, thus accelerating the degeneration process in these areas and causing new pain or other symptoms. 2. Local stiffness: Since part of the spine is fixed together, the flexibility of this area is affected, which can easily cause inconvenience or pain when the patient moves, such as being unable to perform bending or straightening movements.

[0006] For example, the existing Chinese patent document with the publication number CN112754581A discloses a magnetic anastomosis ring system and its anastomosis method. Magnetic anastomosis is a surgical technique that uses magnetic force to achieve tissue connection or repair. This technique is mainly applied to situations where pipeline structures such as the digestive tract and urinary tract need to be reconstructed or repaired. The basic principle of magnetic anastomosis is to use a pair of magnets with strong attraction, place them between two segments of tissue to be connected, and through the action of magnetic force, the tissue gradually approaches and finally heals together. However, its technical goal is limited to the function of tissue healing. Summary of the Invention

[0007] The purpose of the present invention is to provide a magnetic ring for the treatment of scoliosis, which can not only gradually correct and restore scoliosis, but also enable the patient to move the spine to a certain extent without causing significant pain or triggering new diseases.

[0008] To achieve the above purpose, the present invention adopts the following technical solutions: A magnetic ring for the treatment of scoliosis includes a pair of magnets and a long connecting line. The long connecting line forms a ring structure through the pair of magnets. The pair of magnets includes a first pair of magnets and a second pair of magnets. The two ends of the long connecting line are magnetically connected through the first pair of magnets. At least one break point is provided on the long connecting line, and the break point is magnetically connected through the second pair of magnets. A short connecting line is connected between the two magnets of the second pair of magnets. The magnetic adsorption force generated between the two magnets of the first pair of magnets is greater than the magnetic adsorption force generated between the two magnets of the second pair of magnets.

[0009] The long connecting line is wound around two adjacent transverse processes in the spine. The two magnets of the first pair of magnets and the two magnets of the second pair of magnets both have two different states of separating or attracting together. Through the initial spacing adjustment of the two magnets of the pair of magnets, by using the approaching or separating movement of the two magnets of the first pair of magnets and the second pair of magnets respectively, the annular long connecting line slowly contracts, and the spacing between every two adjacent transverse processes in the spine is controlled to different degrees. After the spinal curvature is corrected to a relatively normal state through surgery, this magnetic ring is used to maintain the spine in the normal curvature, and the spine is naturally and slowly corrected, allowing the spine to be corrected and restored at the same time, achieving better treatment of scoliosis. It should be noted that when the patient needs to move and bend the spine, both magnets of the first magnet pair and the second magnet pair will be synchronously separated as the two adjacent transverse processes move away from each other, and will re-adsorb when the spine is restored. The patient is allowed to bend the spine to a certain extent left and right. The process of spine movement will not cause great pain or trigger new diseases. It should be understood that when the spine is bent excessively, the short connecting line will be straightened and the entire long connecting line will be tightened, indicating that the distance between the two transverse processes exceeds the correction requirement range of this magnetic ring, and a slight pain will be formed to warn the patient not to continue bending the spine, ensuring the continuous correction and recovery of scoliosis; It should be noted that the setting of multiple groups of second magnet pairs is to form adjustment controls for multiple stretching distances. When the spine needs to move or the spine is not fully corrected, it is ensured that there is always a second magnet pair that restricts the first magnet pair. Only the second magnet pair closer to the transverse process can perform stretching movement, and the second magnet pair farthest from the transverse process will not be stretched. When the two magnets of the first magnet pair are completely adsorbed together, all the second magnet pairs will be completely separated, stably maintaining the correction function of this magnetic ring.

[0010] Advantages of the present invention: 1. The magnetic ring described in the present invention can, based on different degrees of scoliosis, specifically achieve the gradual correction and recovery of scoliosis after surgical correction treatment; 2. The magnetic ring described in the present invention can allow the patient to move the spine to a certain extent without causing great pain, and can avoid local stiffness or adjacent segment diseases after surgical correction treatment; 3. Compared with existing surgeries, it can cause less damage to the bone tissue of the spine, thus constituting a more effective and safe minimally invasive surgery, making the patient more comfortable and at ease during the spine correction and recovery process.

[0019] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings. Embodiment 1

[0020] As Figure 2 and Figure 3 shown, a magnetic ring for treating scoliosis of the spine 8 includes a magnet pair and a long connecting wire 1. The long connecting wire 1 is connected through the magnet pair to form a ring structure. The magnet pair includes a first magnet pair 2 and a second magnet pair 3. Both ends of the long connecting wire 1 are magnetically connected through the first magnet pair 2. At least one disconnection point is provided on the long connecting wire 1, and the disconnection point is magnetically connected through the second magnet pair 3. A short connecting wire 4 is connected between the two magnets of the second magnet pair 3. The magnetic adsorption force generated between the two magnets of the first magnet pair 2 is greater than the magnetic adsorption force generated between the two magnets of the second magnet pair 3.

[0021] In this embodiment, after surgical correction treatment for the patient's spine 8, the long connecting wire 1 surrounds two adjacent transverse processes 9 in the spine 8. The two magnets of the first magnet pair 2 and the two magnets of the second magnet pair 3 both have two different states of being separated from each other or adsorbed together. Through the adjustment of the initial distance between the two magnets of the magnet pair, by the approach or separation movement of the two magnets of the first magnet pair 2 and the second magnet pair 3 respectively, the annular long connecting wire 1 slowly contracts, and the distance between every two adjacent transverse processes 9 in the spine 8 is controlled to different degrees. After the curvature of the spine 8 is corrected to a relatively normal state through surgery, this magnetic ring is used to maintain the spine 8 in a normal curvature, and the spine 8 is slowly corrected naturally, allowing the spine 8 to correct and recover at the same time, so as to achieve better treatment of scoliosis of the spine 8. For the curvature conditions of different positions of the curved spine 8, there are various different adjustment combinations for the states of the first magnet pair 2 and the second magnet pair 3, which specifically include the following: The first combination: When the Cobb angle at the scoliosis position of the spine 8 is greater than 40°, the two magnets of the first magnet pair 2 are adjusted to be separated from each other, and the two magnets of the second magnet pair 3 are adjusted to be attracted to each other. Since the smaller the distance between the two magnets, the greater the magnetic force, and the magnetic adsorption force generated between the two magnets of the first magnet pair is greater than the magnetic adsorption force generated between the two magnets of the second magnet pair, the mutual attraction between the two magnets of the first magnet pair 2 is greater than the mutual attraction between the two magnets of the second magnet pair 3. However, the mutual approach of the two magnets of the first magnet pair 2 will be restricted by the attraction of the second magnet pair 3, resulting in the two magnets of the first magnet pair 2 being slowly attracted and approaching each other, and then the annular long connecting line 1 slowly contracts. For the case where the scoliosis of the spine 8 belongs to severe scoliosis, the recovery period of the spine 8 is longer. Relying on the mutual restrictive movement of the first magnet pair 2 and the second magnet pair 3, the two transverse processes 9 of the spine 8 cooperate to slowly contract to adapt to the recovery period. When the two magnets of the first magnet pair 2 are completely attracted to each other, it means that the scoliosis of the spine 8 is successfully corrected and restored to the normal state, and the two transverse processes 9 are no longer restricted by the long connecting line 1.

[0022] The second combination: When the Cobb angle at the scoliosis position of the spine 8 is greater than 20° and less than 40°, this position is moderate scoliosis. The two magnets of the first magnet pair 2 and the two magnets of the second magnet pair 3 are both adjusted to be separated from each other. However, the distance between the two magnets of the second magnet pair 3 is less than the distance between the two magnets of the first magnet pair 2, and the difference in magnetic flux density between the first magnet pair 2 and the second magnet pair 3 is small, resulting in the contraction force of the annular long connecting line 1 being less than that of the first combination, but the contraction period is close to that of the first combination to match the overall self-recovery adaptation period of the spine 8.

[0023] The third combination: When the Cobb angle at the scoliosis position of the spine 8 reaches 10° - 20°, this position is mild scoliosis. This combination is for the part of the transverse process 9 between the scoliosis position and the normal position of the spine 8. The two magnets of the first magnet pair 2 need to be adjusted to be attracted to each other, and the two magnets of the second magnet pair 3 are adjusted to be separated from each other. However, the two magnets of the second magnet pair 3 still need to be in a state of mutual attraction to prevent the severely scoliotic part of the spine 8 from affecting the normal part and control the coordinated movement range of the entire spine 8.

[0024] It should be noted that when the patient needs to move and bend the spine 8, both magnets of the first magnet pair 2 and the second magnet pair 3 will synchronously separate due to the two adjacent transverse processes 9 moving away from each other, and will re-adsorb when the spine 8 is restored. The patient is allowed to bend the spine 8 to a certain extent left and right. The process of the spine 8 moving will not cause great pain or trigger new diseases. It should be understood that when the spine 8 is bent excessively, the short connecting line 4 will be straightened and the entire long connecting line 1 will be tightened, indicating that the distance between the two transverse processes 9 exceeds the correction requirement range of this magnetic ring, and a slight pain will be formed to warn the patient not to continue bending the spine 8, ensuring the continuous correction and restoration of the scoliosis of the spine 8.

[0025] It should be noted that since the two magnets of the first magnet pair 2 only attract each other by magnetic force, they can quickly surround the two transverse processes 9 of the spine 8, achieving the effect of quick and convenient installation of this magnetic ring. Embodiment 2

[0026] As Figure 4 and Figure 5 shown, three groups of the second magnet pairs 3 are provided. When the side view projection plane of one group of the second magnet pairs 3 coincides with that of the first magnet pair 2, the side view projection planes of the other two groups of the second magnet pairs 3 can be symmetrically arranged with the first magnet pair 2 as the center.

[0027] In this embodiment, Embodiment 2 is a further limitation and adjustment based on Embodiment 1. One group of the second magnet pairs 3 whose side view projection planes coincide with that of the first magnet pair 2 and the first magnet pair 2 are the main objects of mutual restriction, and the other two groups of the second magnet pairs 3 are auxiliary objects. They can be arbitrarily adjusted to be separated from each other or adsorbed together according to the degree of scoliosis of the spine 8, adjusting the magnet spacing between them so that the length of the long connecting line 1 can be stably contracted and the two transverse processes 9 can be corrected, without the need to finely adjust the magnet spacing of a single group of the second magnet pairs 3, making the installation of this magnetic ring more quick and convenient. When the distance between the two transverse processes 9 increases due to the movement of the spine 8, the other two groups of the second magnet pairs 3 will also be preferentially stretched, forming a more stable synchronous separation and reset. Embodiment 3

[0028] As Figure 6 and Figure 7 shown, five groups of the second magnet pairs 3 are provided. The interval distances between three groups of the second magnet pairs 3 are equal to each other, and the interval distances between the other two groups of the second magnet pairs 3 and the first magnet pair 2 are equal respectively, and the five groups of the second magnet pairs 3 are radially symmetric with each other.

[0029] In this embodiment, Embodiment 3 is a further limitation and adjustment based on Embodiment 1. The additional four groups of second magnet pairs 3 added on the basis of Embodiment 1 can synchronously stretch or contract the partial long connecting lines 1 on the left and right sides of the two transverse processes 9, mainly aiming at the situation where the scoliosis of the spine 8 is severe and the two transverse processes 9 are overly separated and reset, avoiding the pressure injury of the transverse process 9 caused by the tightening of the partial long connecting line 1 when any one of the second magnet pairs 3 is restored and adsorbed, and ensuring the stability and safety of the scoliosis correction treatment of the spine 8.

[0030] It should be noted that the setting of multiple groups of second magnet pairs 3 is not limited to Embodiment 2 and Embodiment 3. Its purpose is to form the adjustment and control of multiple stretching distances. When the spine 8 needs to be moved or the spine 8 is not completely corrected, it is ensured that there is always a second magnet pair 3 restricting the first magnet pair 2. Only the second magnet pair 3 closer to the transverse process 9 can be stretched, and the second magnet pair 3 farthest from the transverse process 9 will not be stretched. When the two magnets of the first magnet pair 2 are completely adsorbed together, all the second magnet pairs 3 are completely separated, and the correction function of this magnetic ring is stably maintained during the correction and recovery of the spine 8. Embodiment 4

[0031] This embodiment is a perfect auxiliary form based on Embodiment 1, Embodiment 2, and Embodiment 3.

[0032] As Figures 2 to 7 shown, two elastic bodies 5 are provided on the outer side surface of the long connecting line 1. The two elastic bodies 5 are respectively equidistant from the center of the first magnet pair 2, and there is a group of second magnet pairs 3 that are respectively equidistant from the centers of the two elastic bodies 5.

[0033] First, the elastic body 5 can increase the contact area between the long connecting line 1 and the transverse process 9, reduce the pressure injury caused by the excessive pressure of the long connecting line 1 on the transverse process 9, and relieve the pain of the patient when correcting or moving the spine 8; second, the elastic body 5 itself also has a flexible effect. When the first magnet pair 2 and the second magnet pair 3 act on the long connecting line 1 respectively, it will not instantaneously generate too large a force on the transverse process 9, playing a certain buffering role; fourth, by limiting the distances between the two elastic bodies 5 and the first magnet pair 2 and the second magnet pair 3 respectively, it is ensured that while the elastic body 5 is in contact with the transverse process 9, the first magnet pair 2 and the second magnet pair 3 can be in a position of restricting and stretching each other.

[0034] The inner side surface of the elastic body 5 is provided with anti-slip patterns 6. The anti-slip patterns 6 play an anti-slip effect, avoiding the long connecting line 1 from detaching from the transverse process 9 when stretching the first magnet pair 2 or the second magnet pair 3.

[0035] The material of the elastic body 5 is one of fiber, silicone, hydrogel, and polyurethane elastomer.

[0036] The fiber has good biocompatibility and biostability, can coexist with human tissues, will not cause rejection reactions, and also has high strength and durability. It also has good stretchability, resilience, flexibility and compliance, can withstand the complex environment in the human body, adapt to changes in the human environment, and reduce tissue damage.

[0037] Silicone has good biocompatibility, excellent fatigue strength, flexibility and toughness. At the same time, it has thermoplastic processing properties and improved elastic strength characteristics, and has excellent biopersistency with the host tissues at the orthopedic implant site. Overall, it shows good mechanical properties and excellent tissue compatibility, enabling it to maintain minimal tissue interaction in the physiological environment and keep the performance deterioration to a minimum for a long time. In addition, silicone is resistant to attacks on human tissues and will not be metabolized by other organisms.

[0038] Hydrogel is an artificial elastic polymer with excellent biocompatibility. It is composed of a 3D structural network passing through the medium and is stabilized by surface tension. Hydrogels are interconnected by grains present in the structure. These grains are insoluble in water and thus play a role in physical cross-linking. Medical implants covered with hydrogels have the dual advantages of ideal volume and surface characteristics, making up for the required mechanical strength and elasticity, and having excellent compatibility when in contact with human bones.

[0039] Polyurethane elastomer is an excellent medical-grade polymer. It can exhibit excellent biocompatibility, biostability, flexibility, toughness and durability, and is suitable for various implantable medical devices; polyurethane elastomer has excellent resistance to metal ion oxidation, environmental stress cracking and hydrolysis, and is thus not easily degraded and dispersed in the biological environment. At the same time, as a super-elastic material, it has excellent compatibility when in contact with human bones. Example 5

[0040] The magnetic flux density of the magnets in the magnet pair is 0.2T - 2T. Controlling the magnetic flux density of the two magnets in the magnet pair within 0.2T - 2T can, on the one hand, make the magnetic field between a pair of magnets stable and concentrated, with an obvious magnetic flux gain effect, reduce the difficulty of installation and adjustment, simply achieve the effect that can only be produced by multiple magnets, and there will be no situation of insufficient magnet suction. On the other hand, it can better balance the difference in the change of magnetic adsorption force between the first magnet pair and the second magnet pair, continuously restrict each other during the spinal correction recovery period, and also keep the two magnets of each of them in a stable adsorption state, ensuring the treatment effect of spinal correction and recovery. Example 6

[0041] As Figure 8As shown, the outer surface of the magnets of the magnet pair is wrapped with an isolation layer 7, and the isolation layer 7 is made of a biocompatible material. The isolation layer 7 made of a biocompatible material can effectively avoid the rejection reaction of the human body caused by the magnet and can be implanted into the human body for a long time.

[0042] The biocompatible material is one of TPU material or TPE material.

[0043] It should be noted that the TPU material is composed of the following components by mass percentage: aliphatic TPU: 80 - 90wt%, plasticizer: 5 - 10wt%, antioxidant: 0.1 - 0.5wt%, filler: 1 - 3wt%, functional additive: 2 - 5wt%.

[0044] Among them, the usage requirements for the components of the above TPU material will be described in detail as follows: (1) The aliphatic TPU selects medical - grade TPU materials such as the Elastollan series of BASF or the Irogran series of Huntsman; (2) The plasticizer selects triethyl citrate (TEC) or tributyl citrate (TBC). These plasticizers not only have good biocompatibility but also are biodegradable and comply with FDA regulations; (3) The antioxidant selects antioxidant 1010 (pentaerythritol tetrakis [β - (3,5 - di - tert - butyl - 4 - hydroxyphenyl) propionate]) which can provide effective antioxidant protection to prevent material aging; (4) The filler selects nanocellulose which can enhance the mechanical strength of the material without affecting its softness and at the same time maintain biocompatibility; (5) The functional additive selects barium sulfate (BaSO4). If X - ray visibility is required, an appropriate amount of barium sulfate can be added as a radiopaque contrast agent to confirm the position of this magnetic ring in the human body and the current restraint state of the spine, and it is also convenient for the quick removal of this magnetic ring during surgery after the spine has fully recovered.

[0045] It should be noted that the TPE material is composed of the following components by mass percentage: nano - crystal - structure - controlled α - olefin elastomer: 70 - 80wt%, medical - grade polypropylene: 16 - 22wt%, compatibilizer: 0 - 10wt%, antioxidant: 0.3 - 1wt%, functional additive: 2 - 5wt%.

[0046] Among them, the usage requirements for the components of the above TPE material will be described in detail as follows: (1)The melt index (at 230 °C, 2.16 kg) of the nano-crystal structure-controlled α-olefin elastomer is 5 - 10 g / 10 min, and the Vicat softening point is 125 - 140 °C. Using the nano-crystal structure-controlled α-olefin elastomer as the base material, its crystal structure is controlled at the nano level and has the advantages of a three-dimensional structure, small relative density, good flexibility, high mechanical strength, and excellent biocompatibility with biological tissues; (2)The melt index (at 190 °C, 2.16 kg) of medical-grade polypropylene is 5 - 10 g / 10 min, and the melting point is 130 - 150 °C. Medical-grade polypropylene is used to adjust the material strength and improve the processing performance, making the overall material have stable performance; (3)The compatibilizer is odorless maleic anhydride grafted polypropylene, which is used to improve the affinity and dispersibility of the nano-crystal structure-controlled α-olefin elastomer and medical-grade polypropylene, effectively enhancing the dispersion degree of the nano-crystal structure-controlled α-olefin elastomer in medical-grade polypropylene, making the overall material have good mechanical properties and aging resistance; (4)The antioxidant is antioxidant 1010 or antioxidant 168, which can provide effective antioxidant protection and prevent material aging; (5)The functional additive is barium sulfate (BaSO4). If X-ray visibility is required, an appropriate amount of barium sulfate can be added as a radiopaque contrast agent.
