Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to an artificial spinal canal for preventing spinal nerve compression. Background Art

[0002] Due to the special anatomical location of the spine, spinal tumor surgery is risky and difficult. In particular, the problem of recurrence of malignant tumors and metastatic tumors has always troubled spinal surgeons. Spinal nerve compression caused by tumor recurrence has led to a high incidence of paraplegia. The reason is that the tumor destroys or surgically removes the anatomical structure originally used to protect the dura mater sac and spinal cord - the spinal canal. The current surgical methods for spinal tumors include total vertebral resection and partial vertebral tumor resection. For patients who cannot undergo radical total vertebral resection but need timely decompression of the spinal cord, some scholars have tried "separation surgery". After the operation, bone cement is used to fill the space between the back of the vertebral body and the dura mater sac to block the compression caused by tumor recurrence. However, the problems of bone cement displacement and compression on the sides and back of the dura mater sac cannot be solved. After tumor recurrence, it can still bypass the bone cement and cause spinal nerve compression. There is currently no effective way to solve the problem of spinal nerve compression caused by tumor recurrence.

[0003] When the existing artificial spinal tube is used, such as application number CN201810077583.6, it relates to an artificial spinal tube for preventing spinal nerve compression, and the artificial spinal tube includes an artificial spinal tube body, a transverse connector, and a fixing device; the artificial spinal tube body is connected to the fixing device through the transverse connector. Its advantages are as follows: an artificial spinal tube for preventing spinal nerve compression of the present invention is designed according to the shape and size of the spinal tubes of different segments of the human spine to be suitable for different segments of the artificial spinal tube, and the tumor tissue around the dura mater sac is removed by posterior spinal surgery, and then the dura mater sac of the corresponding segment is placed around the dura mater sac, and the transverse connector is finally fixed together with the fixing device to achieve stability, and its supporting effect can effectively prevent tumor recurrence and scar hyperplasia from causing compression to the dura mater sac and spinal nerves at 360°, and can also effectively avoid adhesion between surrounding scar tissue and the dura mater sac and nerve roots; however, in the above-mentioned technology, the artificial spinal tube body is mainly an integrated structure, and when deformed, it is easy to cause the product to compress the nerves. For this reason, we propose an artificial spinal tube for preventing spinal nerve compression to solve the above-mentioned problems. Summary of the invention

[0004] In view of the above problems, the present invention proposes an artificial spinal canal for preventing spinal nerve compression. The artificial spinal canal for preventing spinal nerve compression mainly utilizes an outer ring strip arranged on the outer side of the conical tube to be annularly sleeved according to the adaptability needs of the patient. After the annular sleeve, the combined spinal canal components can achieve a coordinated operation. Since the outer ring strip and the porous layer are porous structures, and the cavity layer has a hollow tube layer structure, the effect of adaptive deformation can be achieved during compression, and the comfort of the patient can be effectively improved during subsequent recovery, thereby preventing product compression. Due to the porous structure, the product can be quickly absorbed and metabolized during subsequent recovery, ensuring the patient's reconstruction.

Since the outer ring strip 404 and the porous layer 405 are porous structures, the absorption effect can be effectively achieved during subsequent healing, which is convenient for The subsequent effective healing and recovery of the patient, because the cavity layer 406 has a relatively hollow structure, can achieve the effect of adaptive deformation according to the needs of movement during recovery, when the combined spinal canal component 4 is installed by medical staff, the two ends of the cone tube 401 are penetrated and connected to the through-hole seat 308, and after penetration, the first suture seat 309 is sutured and connected to the side of the through-hole seat 308, and after suturing, the outer side of the through-hole seat 308 is adaptively installed with a connecting strip 307 according to the needs of the patient's body shape, so that the appropriate size is adapted to the patient's body shape, and a shock-absorbing group strip 306 is set at one end of the connecting strip 307. Since the shock-absorbing group strip 306 has a shock-absorbing effect, it can effectively achieve a buffering effect during the circular movement, thereby The firmness of the equipment is improved and the comfort of the patient is improved, and the effect of the patient's exercise is guaranteed. Then, an upper strip 305 is set at the inner end of the shock-absorbing group strip 306 for fixing, so that the hinge base 303 is movably connected to the upper hinge strip 302, so that it can be matched according to specific needs. After the matching operation, the outer clip 301 cooperates with the matching operation of the upper hinge strip 302 and the hinge base 303, so that the outer clip 301 is fixed to the outer side of the fixing frame 201. After clamping, the matched outer clip 301 is bolted with a fixing bolt 304 to prevent the product from being misplaced and ensure the therapeutic effect of the product.
