Embodiment Construction

[0007] The present invention will be described in further detail below according to the drawings and embodiments. As shown in the figure: an artificial lamina, made of titanium alloy, including a lamina body, the lamina body is an arc-shaped mesh lamina 4, and the sides of the arc-shaped mesh lamina 4 are provided with wings 1, and the wings 1 are designed There are screw holes 2, the back side of the arc-shaped mesh lamina 4 is provided with mesh spines 3, and the arc-shaped mesh vertebra 4 and the mesh spines 3 are provided with mesh holes 5. The flank 1 is provided with two screw holes 2 for selection; the section of the curved mesh lamina 4 is roughly semicircular.

[0008] The artificial lamina simulates the human lamina, and the shape of the curved reticular lamina 4 and the reticular spine 3 is similar to that of the human lamina; after the laminectomy, an artificial lamina of appropriate size is selected, and the artificial lamina is placed on both sides of the flank 1...

Abstract

The invention relates to a human body vertebral column implanting appliance, in particular to an artificial vertebral plate, which comprises a vertebral plate body. The artificial vertebral plate is characterized in that the vertebral plate body is an arc-shaped netty vertebral plate, side wings are arranged on two sides of the arc-shaped netty vertebral plate, screw holes are arranged on the side wings, netty bumps are arranged on the back side of the arc-shaped netty vertebral plate, and meshes are arranged on the arc-shaped netty vertebral plate and the netty bumps. The invention is used for reconstruction by the aid of the artificial vertebral plate after laminectomy in posterior spinal surgery for a human body, coloboma of a vertebral plate is repaired, the human body vertebral plate is imitated, spinal cord compression caused by swelling of posterior tissues of the spinal cord of the human body after the surgery is prevented, completeness of a vertebral canal is kept, the vertebral column of the human body is stabilized, and the spinal cord is protected. During usage, the artificial vertebral plate is fixed on a transverse process or a vertebral pedicle of the vertebral column of the human body by screws via the screw holes on the side wings on the two sides, and paraspinal muscle, supraspinal ligament and the like are sewn on the meshes of the netty bumps. The vertebral plate body is the arc-shaped netty structure, so that the volume of the vertebral canal is guaranteed; and the netty structures of the arc-shaped netty vertebral plate and the netty bumps bring convenience for growth of tissues on two sides so as to realize tissue connection.

Description

technical field [0001] The invention relates to a human spinal implant instrument, in particular to an artificial lamina. Background technique [0002] In the past, laminectomy resulted in absence of laminae in spinal surgery, and swelling of the soft tissue behind the spinal canal could easily cause spinal cord compression and result in spinal cord injury. The artificial lamina is used for reconstruction after laminectomy in spinal surgery. It imitates the human lamina to prevent spinal cord compression caused by postoperative swelling of the tissue behind the spinal cord and maintain the integrity of the spinal canal. The existing artificial lamina is not conducive to the growth of tissues on both sides. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an artificial lamina that is simple in structure, easy to use, and conducive to the growth of tissues on both sides of the lamina. [0004] The technical soluti...
