Description

Spinal fixation system and device TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, in particular to a spinal fixation system and device. BACKGROUND

[0002] Clinically, spinal internal fixation can restore the stability of the spine and maintain the support function of the spine. At present, when performing spinal internal fixation, materials with high support and good fixation (such as stainless steel materials, titanium alloy materials, etc.) are generally used for permanent fixation of the affected part of the spine. However, for parts such as the lumbar spine and the cervical spine, which have a greater impact on the range of motion, the use of the above permanent fixation method will seriously affect the daily life of the patient. In particular, for children and adolescents with scoliosis, early surgery for scoliosis can correct the deforming factors as soon as possible, prevent the progression of spinal deformity, prevent the limitation of heart and lung function, and ensure normal body development. When using the permanent fixation method in the prior art to implant and fix the affected part of the spine, a second surgery is generally required to remove the implant, causing secondary trauma to the patient.

[0003] Therefore, when performing spinal internal fixation, it is necessary to minimize the impact on the growth and development of the spine and the range of motion of the spine while ensuring the smooth implementation of the surgery and the orthopedic effect, preventing the progression of deformity, restoring the balance of the spine, correcting deformity as much as possible, preserving as many active segments of the spine as possible, and preventing nerve damage. It is a problem that needs to be solved at present. If the current situation of requiring a second surgery to cause trauma again can be changed, it is the expectation of clinical orthopedic medical staff and the blessing of patients. SUMMARY

[0056] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0057] For example, FIG. 1 is a flowchart of a spinal fixation system of the present application. The present embodiment provides a spinal fixation system, which comprises:

[0058] An acquisition unit is configured to acquire a spinal region image containing a target region to be processed.

[0059] A processing unit is configured to determine a spinal region activity of the target region to be processed according to the spinal region image, and divide the target region to be processed into a high-activity region or a low-activity region according to the activity. The target region to be processed is a scoliosis or kyphosis region or a lumbar region in a spinal region of a subject. The spinal region image can be a coronal spinal image or a sagittal spinal image. The activity of the spinal region is a preliminary examination of the activity of the spinal region, which is used for prevention and timely treatment of spinal disorders. The cervical spine segment and the lumbar spine segment have the largest range of motion. The thoracic spine segment has a smaller range of motion. The sacral vertebrae are fused into bone blocks and have almost no activity. The coccyx vertebrae are fused and fixed and have no activity.

[0060] A recommendation unit is configured to output a spinal fixation scheme, which is to fix a temporary fixation part in the high-activity region and / or fix a permanent fixation part in the low-activity region.

[0061] The temporary fixation part comprises absorbable pedicle screws 11 and absorbable fixation rods 12 which are adapted to the absorbable pedicle screws 11; the permanent fixation part comprises non-absorbable pedicle screws 21 and non-absorbable fixation rods 22 which are adapted to the non-absorbable pedicle screws 21.

[0062] The criteria for judging the activity degree comprise a first criterion, which comprises:

[0063] The high activity degree region comprises the region between the lumbar vertebrae 1 and the sacrum 1 (the region of all lumbar vertebrae and the sacrum 1, L1-S1), the region between the cervical vertebrae 1 and the thoracic vertebrae 1 (the region of all cervical vertebrae and the thoracic vertebrae 1, C1-T1); the high activity degree region preferably comprises the region between the lumbar vertebrae 3 and the sacrum 1 (in particular, clinically common L3-L4, L4-L5, L5-S1), the region between the cervical vertebrae 1 and the cervical vertebrae 7 (C1-C7); the low activity degree region comprises the region of all thoracic vertebrae, and the region of the spinal column region except the high activity degree region. The cervical vertebrae is abbreviated as C, the thoracic vertebrae is abbreviated as T, the lumbar vertebrae is abbreviated as L, and the sacrum is abbreviated as S.

[0064] The processing unit further comprises: a unit for determining the severity level of the target region to be processed according to the spine site image, and dividing the target region to be processed into a severe region or a non-severe region according to the severity level; the severity level comprises the judgment of the scoliosis angle and whether the lumbar intervertebral disc is diseased; for the scoliosis angle, the judgment of the severe region or the non-severe region is based on the Cobb angle; for whether the lumbar intervertebral disc is diseased, the judgment of the severe region or the non-severe region is based on whether the lumbar intervertebral disc compresses the nerve root and the cauda equina; or whether obvious clinical symptoms such as low back pain occur; the disease of the lumbar intervertebral disc is a clinical syndrome that the partial or whole rupture of the annulus fibrosus of the lumbar intervertebral disc, the nucleus pulposus tissue protrudes backward from the rupture, and stimulates or compresses the nerve root and the cauda equina. Among them, when there are usually multiple arcs on the spine, the Cobb angle of each arc is measured and marked; after the X-ray film is taken, the doctor draws a line to measure the Cobb angle, and the Cobb angle within 10° is normal, and the Cobb angle greater than 10° is scoliosis. The severity of scoliosis is usually evaluated by measuring the angle of lateral bending, and the most commonly used method for angle measurement is the Cobb angle measurement method. The X-ray film used for measurement is the standard full-length frontal position of the spine. First step: determine the end vertebra of lateral bending. The upper and lower end vertebrae refer to the vertebrae with the maximum inclination on the concave side of the lateral bending. The intervertebral space on the convex side of the lateral bending is wider, and the first vertebra on the concave side whose intervertebral space starts to widen is considered not to belong to the curve, so its adjacent vertebra is considered to be the end vertebra of the curve. Second step: draw a horizontal line on the upper edge of the vertebral body of the upper end vertebra, and draw a horizontal line on the lower edge of the vertebral body of the lower end vertebra. Make a vertical line on each of the two horizontal lines. Third step: the intersection angle of the two vertical lines is the Cobb angle. Note: for larger lateral bending, the direct intersection angle of the two horizontal lines is also equal to the Cobb angle. The angle of lateral bending is measured by this angle. If the Cobb angle is less than 25 degrees, no surgical treatment is needed, and posture correction action training can be performed under the guidance of a rehabilitation therapist, and dynamic observation is performed every 4-6 months; if 25 degrees < Cobb angle < 50 degrees, brace treatment is recommended; if the Cobb angle is greater than 50 degrees, surgical treatment is recommended. Furthermore, in the spine region, the top cone region of severe scoliosis, the vertebrae with heavy vertebra rotation, and the vertebrae in the osteotomy region are severe regions, the vertebrae region close to the severe region is a transition region, the transition region is defined as a non-severe region, and the region far from the severe region is a normal region without special circumstances. No surgical instrument is implanted for fixation; if L2-L5 belongs to the severe region, L6-L7 belongs to the normal region, then the vertebra region between L5 and L6 is the transition region, i.e. the non-severe region.

[0065] Optionally, the spinal fixation scheme further comprises: fixing the permanent fixation part in the severe region, and / or fixing the temporary fixation part in the non-severe region; or, the spinal fixation scheme further comprises: fixing the permanent fixation part in the severe region and the low-activity region, and / or fixing the temporary fixation part in the non-severe region and the high-activity region.

[0066] The activity degree judgment criterion further comprises a second judgment criterion, comprising: judging the age of the to-be-measured person according to the spinal part image;

[0067] When the age of the person to be measured is less than or equal to N, the high-activity region includes all the spinal regions except the region judged to be the severe region, and the low-activity region is the region judged to be the severe region; when the age of the person to be measured is greater than or equal to N, the second judging criterion is consistent with the first judging criterion. The specific value of N is determined according to any one of the following ways: 1. virtual age: calculated according to the calendar year experienced after birth, that is, 1 year old as soon as born, and then increase 1 year for every new year; generally calculated according to the lunar new year, or calculated according to the Gregorian calendar; 2. age in years: also known as real age, refers to the number of years experienced or birthdays from birth to the time of calculation; 3. exact age: refers to the number of days experienced from the date of birth to the date of calculation. It is more accurate than the age in years to reflect the actual survival time of people. According to the determination method of N, N is not limited to a natural integer, but preferably 10; for children under 10 years old, the growth potential of the spine needs to be considered, and in the important growth region of the spine, the more fixed, the more limited the growth, so it is necessary to minimize the fixation of the spinal vertebrae, and the fewer the number of fixed vertebrae, the better the fixed scheme. Specifically, when the vertebra M is the severe region, the P vertebrae above and / or below the vertebra M are the non-severe region; for example: L6 is judged to be the severe region / high-activity region (i.e. the most severe vertebra of scoliosis or inclination), then L5 and L7 at the upper and lower ends of L6 are the non-severe region (low-activity region). For the scoliosis deformity of children under 10 years old (early-onset scoliosis), the treatment of spinal surgery has always been a difficult problem, because the children at this stage are in the peak period of growth and development, and the scoliosis will undoubtedly have a serious negative impact on the development of the child's skeleton and important organs such as heart and lung. In recent years, relevant research has also shown that the first peak period of longitudinal growth and development of the spine is from birth to 5 years old (with a stable growth rate of about 2 cm per year). During this period, if the child's spinal deformity continues to progress, it will eventually compress the thoracic organs, reduce the thoracic volume, and thus compress the lung parenchyma and reduce the lung volume. If the child cannot be treated in time or is treated improperly, it will have a serious physical deformity and limited heart and lung development in the child, affecting the child's quality of life, and even causing heart and lung failure and even death. However, the traditional orthopedic fusion technique will inevitably lead to the loss of the growth function of the spine in the peak period of growth and development, thereby causing the shortening of the trunk and the limited development of the heart and lung function. Therefore, it is necessary to adopt internal fixation implant to correct the spinal deformity and stabilize the spine while avoiding spinal fusion to maintain the normal growth of the spine, which is a method that the spinal surgeons have been looking for.

[0068] After the acquisition unit, further comprising an identification unit for identifying whether to implant the target region to be processed;

[0069] The identification of whether to implant the target region to be processed includes: obtaining a scoliosis angle of the target region to be processed; comparing the scoliosis angle with a standard scoliosis angle to obtain a result of whether the scoliosis angle meets the standard; if the scoliosis angle does not meet the standard, implanting the target region to be processed is needed, and the processing unit is implemented; if the scoliosis angle meets the standard, implanting the target region to be processed is not needed, and the processing unit is not needed to be implemented.

[0070] And / or, obtaining whether the intervertebral disc of the target region to be processed is diseased; if the intervertebral disc is diseased, implanting the target region to be processed is needed, and the processing unit is implemented; if the intervertebral disc is not diseased, implanting the target region to be processed is not needed, and the processing unit is not needed to be implemented.

[0098] Any one of the following applications:

[0099] Application of the above system in diagnosis of disease development; optionally, the disease includes lumbar disc herniation, scoliosis in children and adolescents, etc.

[0100] Optionally, the simple nucleus pulposus removal surgery used in the lumbar disc herniation;

[0101] Optionally, the AIS surgery for adolescent idiopathic scoliosis (AIS), the CS surgery for congenital scoliosis in children (CS), etc. used in the scoliosis in children and adolescents.

[0102] The use method is as follows:

[0103] During the surgery, according to the image of the spinal part of the patient, the appropriate temporary fixation part and / or permanent fixation part are selected for individual or joint use, and are placed at the appropriate spinal segment.

[0104] 1. When the temporary fixation part is applied in the simple nucleus pulposus removal surgery, the absorbable pedicle screw 11 and the absorbable fixation rod 12 are implanted after the simple nucleus pulposus removal surgery to form a temporary fixation between the upper and lower vertebral bodies of the simple nucleus pulposus removal. The absorbable internal fixation is made of magnesium-aluminum alloy, which can be completely degraded in the body for about 6 months. At that time, the fibrous ring of the surgical segment has formed a scar, and the nucleus pulposus will not come out again, and the lumbar vertebrae recover normal activity. The unit can be made of absorbable magnesium-aluminum alloy or other in-vivo absorbable materials with certain strength. The screw is designed in the form of a universal pedicle screw, and the thread can be double-rib structure to make up for the insufficient strength of magnesium-aluminum alloy and avoid internal fixation failure. The fixation rod is also made of absorbable material and is connected to the absorbable pedicle screw 11 through the absorbable tail screw. The simple nucleus pulposus removal surgery is one of the surgical methods for treating simple lumbar disc herniation. The specific operation is as follows: the paraspinal muscles are stripped through the posterior spinal route, the spinal lamina space is performed, the lamina window is opened, and the spinal cord and nerve root are exposed; the nerve root is pulled, the protruding intervertebral disc is explored, the intervertebral disc annulus fibrosus is sharply incised, and the protruding intervertebral disc nucleus pulposus is removed by using nucleus pulposus forceps and other tools; then the incision is closed layer by layer. The advantage of simple nucleus pulposus removal surgery is that the surgical incision is small, no internal fixation is needed, fusion surgery is avoided, and the lumbar activity is maximally preserved. However, due to the destruction of the annulus fibrosus structure, the relative movement between the vertebral bodies will make the nucleus pulposus in the annulus fibrosus more likely to fall out into the spinal canal after the surgery, resulting in recurrence. Generally, for patients after simple nucleus pulposus removal surgery, doctors recommend bed rest for more than 2 weeks to avoid the nucleus pulposus from falling out again due to intense activity of the spine; after the annulus fibrosus breaks and forms a scar, the waist is actively moved. At present, elastic internal fixation rods are used clinically as a spinal fixation system after simple nucleus pulposus removal surgery, but the elastic range of elastic fixation is limited, which still limits the activity of the lumbar vertebrae. If the temporary fixation part is applied in this surgery according to the scheme in this embodiment, the nucleus pulposus can be effectively prevented from falling out again after simple nucleus pulposus removal surgery, and the recurrence of lumbar disc herniation can be avoided, while avoiding lumbar fusion internal fixation surgery and maximizing the preservation of lumbar activity.

[0105] 2. When the temporary fixation part and the permanent fixation part are used together, before the scoliosis correction, the expected internal fixation screw placement scheme needs to be designed: titanium alloy or cobalt-chromium-molybdenum alloy screws / lamina hooks are used for strong permanent internal fixation in the top vertebra area of severe scoliosis or the vertebra with heavy vertebral rotation or the vertebra in the osteotomy area; magnesium alloy absorbable pedicle screws 11 / lamina hooks are used for temporary fixation in the end vertebra of scoliosis or the vertebra with greater influence on spinal activity (such as the lumbar spine). The permanent internal fixation system and the temporary internal fixation system can be connected by absorbable connectors and absorbable internal fixation rods, or can be connected by absorbable and non-absorbable mixed internal fixation rods.

[0106] For example, the combination of temporary fixation and permanent fixation is applied in the surgery of adolescent idiopathic scoliosis (AIS). For AIS patients with lumbar scoliosis, if the distal fusion vertebrae are fused to L4 or L5, the lumbar activity will be significantly reduced. However, for patients with severe inclination of L4 or L5, if L4 or L5 is not fused and fixed, the scoliosis cannot be fully corrected. Therefore, the absorbable temporary fixation system is used to correct and fix L4 or L5 intraoperatively, and after the absorbable internal fixation is absorbed by the body (6 months are needed), the scoliosis correction is maintained for about 6 months, and at this time the L4 or L5 vertebral activity is restored. Therefore, the absorbable internal fixation system can achieve intraoperative correction and fixation, and also preserve the lumbar activity without damage.

[0107] The combination of temporary fixation and permanent fixation is applied in the surgery of congenital scoliosis (CS). For patients with single hemivertebra congenital scoliosis, the posterior one-stage hemivertebra resection short segment (one segment above and one segment below the osteotomy) fixation and fusion surgery is the gold standard for treatment. However, this surgery is only effective for cases with small scoliosis degree and no long compensatory curve, and simple short segment fixation can close the gap between the osteotomies.

[0108] For the patients with large scoliosis angle and long arc, simple hemivertebra resection and short segment fixation may not completely correct the deformity, and sometimes more than 3 segments need to be fixed and fused to enhance the screw holding force and achieve better correction. However, for children, fixing and fusing longer segments means losing the growth potential of the fixed and fused segments and failing to achieve normal growth. Posterior spinal fixation and fusion without fusion of the anterior vertebral body may lead to crankshaft phenomenon, causing coronal plane imbalance and aggravating scoliosis. For such patients, we can use absorbable internal fixation system for temporary internal fixation at the distal end of the osteotomy gap, and permanent internal fixation for the osteotomy segment. After the osteotomy gap is fused and the correction effect is maintained for about 6 months, the temporary internal fixation is absorbed by the body, releasing the tethering effect of the internal fixation on the spine, correcting the deformity while preserving the normal growth and development of the spine, and avoiding coronal plane imbalance such as crankshaft phenomenon. If the scheme in the embodiment is used for temporary fixation in children and adolescents with scoliosis, it can minimize the fusion segments and minimize the impact on the growth and development of the spine and the range of motion of the spine, which is a problem that needs to be solved in clinical practice. Since children and adolescents are still in the process of spinal growth and development, early spinal fusion surgery or too many fusion segments will limit the growth and development of the spine or limit the range of motion of the spine to some extent. Incorrect surgery timing or incorrect spinal fusion segments may even lead to increased spinal deformity and loss of range of motion, affecting daily life. Currently, the solution to the problem of scoliosis in children and adolescents in clinical practice is to perform one-stage correction surgery and implant internal fixation, and then perform two-stage surgery to remove the internal fixation after the bone is fused. For patients, this requires two surgeries and causes more trauma.

[0109] Spinal fixation is widely used in clinical practice. When a patient has a spinal fracture or needs spinal decompression, the posterior accessory structure cone plate is removed, and a nail rod system is used to fix the unstable vertebrae for surgery. The surgical approach includes posterior approach, anterior approach, and lateral anterior approach.
