Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Example one
This embodiment discloses a lumbar vertebrae way of escape vertebral plate reconstruction device. The device of this embodiment is used to reconstruct the lamina after a complete resection of the lamina.
Referring to fig. 1 and a1, the device of the present embodiment includes a artificial lamina 100, the front part of the artificial lamina 100 is configured with an upper protrusion 200, the upper protrusion 200 is provided with an upper slot 210 facing the upper spinous process a100 and penetrating in the vertical direction; the two upper side walls 220 of the upper slot 210 are respectively provided with an upper spinous process slot 221. The artificial lamina 100 is constructed at the rear part with a lower protrusion 300 having the same structure as the upper protrusion 200, the lower protrusion 300 is provided with a lower slot 310 facing the lower spinous process c100 and penetrating in the vertical direction, the two sides of the lower slot 310 are respectively opened with a lower spinous process slot 321, and the middle part of the artificial lamina 100 has a left lateral plate 410 and a right lateral plate 420 extending at both sides.
In this embodiment, after the laminectomy, the doctor cuts the superior spinous process a100 and the inferior spinous process c100 through the superior spinous process hole aligned with the superior spinous process groove 221 and the inferior spinous process hole aligned with the inferior spinous process groove 321, respectively. The medical staff connects the artificial vertebral lamina 100 with the spinous process of the upper vertebral lamina and the spinous process of the lower vertebral lamina by inserting the upper rotating shaft in the upper spinous process hole and the upper spinous process groove 221 and inserting the lower rotating shaft in the lower spinous process hole and the lower spinous process groove 321.
The structure of the artificial vertebral plate 100 can perform systematic reconstruction of the vertebral plate after the lumbar vertebra is cut off, and medical personnel can couple the upper spinous process a100 and the lower spinous process c100 with the artificial vertebral plate 100 after the vertebral plate is cut off, so that the artificial vertebral plate 100 can be fixedly installed on the spine; meanwhile, the side plates on the two sides can prevent the soft tissue from easily extending into the vertebral plate and being adhered to the nerve roots and the like after being cut.
Preferably, the upper spinous process groove 221 is filled with an upper elastic fibrous body, and a portion of the upper rotation shaft located in the upper spinous process groove 221 is pierced through the elastic fibrous body. The lower spinous process groove 321 is filled with a lower elastic fibrous body, and a portion of the lower rotating shaft located in the lower spinous process groove 321 penetrates through the lower elastic fibrous body. The upper and lower elastic fibers can act as artificial ligaments to move the artificial lamina 100 relative to the upper and lower vertebral plates.
Referring to fig. 2, the left and right side plates 410 and 420 are formed at the bottom with a movable slot 411 for receiving the posterior articular processes (b110 and b120) of the removed portion of the vertebral plate. Since the lamina is removed in a surgical procedure, the slot 411 of this embodiment is sized to receive the articular process to the maximum extent possible, i.e., to have a maximum diameter that is greater than any cross-section of the articular process.
Preferably, the movable slot 411 is filled with elastic fiber bodies, so that the collision of the vertebral bodies in the movable slot 411 is reduced, and the injury possibly borne by a patient is reduced.
Referring to fig. 3, since the spine is accompanied by undesirable forward curvature, the upper protrusion 200 of the present embodiment is tilted upward relative to the artificial vertebral plate 100; the lower protrusion 300 is tilted downward relative to the artificial lamina 100. The artificial lamina 100 has a bottom slot 430 at the west of the middle for receiving the middle of the lamina.
Further, the lower spinous process groove 321 of the present embodiment is configured as a plurality of circular grooves that are connected to each other, so as to increase the range of motion of the artificial vertebral plate 100 relative to the lower vertebral plate and reduce the influence on the daily life of the patient.
Example two
Referring to FIG. 4, the difference between the first and second embodiments is that the device is used to reconstruct the portion of the left lamina after removal of the left lamina. The artificial lamina 100 of this embodiment has only the left side plate 410 extending leftwards for preventing the exposed vertebral body from adhering to the nerve root after the soft tissue is easily inserted into the left side of the lamina and removed.
EXAMPLE III
Referring to FIG. 5, the difference between the first and third embodiments is that the device is used to reconstruct the portion of the lamina on the right side after removal of the lamina on the right side. The artificial vertebral plate 100 of this embodiment has only the right side plate 420 extending rightwards for preventing the exposed vertebral body from adhering to the nerve root after the soft tissue is easily inserted into the right side of the vertebral plate and removed.
Example four
Referring to fig. 6, the present embodiment further discloses a lumbar posterior vertebral plate reconstruction device capable of flexibly performing vertebral plate reconstruction according to the patient condition after completely cutting the vertebral plate.
The device of this embodiment includes two structurally symmetrical half-laminae. The two lamina halves are configured with axial holes 500 on opposite sides. The two half vertebral plates are fixed at both ends of a rotation shaft through the shaft holes 500, respectively.
The front parts of the two hemilaminae constitute an upper protrusion 200 for connection with the superior spinous process a 100; the upper protrusion 200 is opened with an upper slot 210 which is upward and vertically penetrates; the upper side walls 220 of the two sides of the upper slot 210 are respectively provided with three upper spinous process slots 221; the rear parts of the two hemilaminae constitute a lower protrusion 300 for connection with the superior spinous process a 100; the lower protrusion 300 has a lower groove 310 that is downward and vertically penetrates; the lower side walls 321 of both sides of the lower slot 310 are respectively provided with three lower protruding ratchet slots 321.
Through the scheme, medical staff can adjust the relative angle of the two half vertebral plates through the rotating shaft according to the actual state of the spine of a patient after the vertebral plate is cut off, and the two half vertebral plates and the spinous processes are sufficiently fixed by the rotating shaft after the protruded holes are formed on the upper spinous process a100 and the lower spinous process c100, so that the vertebral plate reconstruction is more flexible.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
