Problems solved by technology

[0003] However, the traditional steel plates have been designed to fit different sizes on the surface of the vertebral body. It is necessary to peel off the periosteum and ligate the blood vessels of adjacent vertebral body segments, which affects the blood supply and healing of the bone, affects the blood supply of the spinal cord, and affects the fusion rate of bone grafting and patients.

Embodiment 1

[0032] Such as figure 1 , 3 As shown in , 4, the anterior thoracolumbar adjustable zero-profile minimally invasive support steel plate disclosed by the present invention includes a support body, the support body includes a support part A1 and a support part B2, and the support part B2 has a laterally protruding convex part 3 One end of the supporting part A1 is provided with a groove for accommodating the raised part 3; one surface of the raised part 3 is an inclined surface, the inclined direction of the inclined surface is perpendicular to the protruding direction of the raised part 3, and the inclined surface is provided with tooth-shaped protrusions. A4, the protruding portion 3 has a tooth-shaped protrusion B5 on the other surface opposite to the inclined surface, the tooth-shaped protrusion A4 and the tooth-shaped protrusion B5 are arranged along the protruding direction of the protrusion 3, the groove and the tooth-shaped protrusion There is a tooth-shaped protrusion C...

Embodiment 2

[0037] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the cross-section of the support body perpendicular to the tooth width direction of the tooth-shaped protrusion A4 is arc-shaped, and the arc-shape protrudes outward in the upward direction of the slope. The cross section of the support body perpendicular to the tooth width direction of the tooth-shaped protrusion A4 is thin in the middle and thick at both ends, and the thickness at both ends is 4mm, forming a support surface.

Abstract

The invention relates to a thoracolumbar spine anterior adjustable minimally-invasive supporting steel plate with zero incisura. The supporting steel plate comprises a supporting body; the supporting body comprises a supporting portion A and a supporting portion B; the supporting portion B is provided with a protruding portion extending in the transverse direction, and a groove for containing the protruding portion is formed in one end of the supporting portion A; one face of the protruding portion is an inclined face, the inclining direction of the inclined face is perpendicular to the extending direction of the protruding portion, tooth-shaped protrusions A are arranged on the inclined face, tooth-shaped protrusions B are arranged on the other face, opposite to the inclined face, of the protruding portion, and tooth-shaped protrusions C are arranged on the side wall, right facing the tooth-shaped protrusions B, of the groove and matched with the tooth-shaped protrusions B. Through double-side gear locking of the supporting portion A and the supporting portion B, the supporting portion A and the supporting portion B are locked firmly, the size can be automatically adjusted, and operation is easy. The supporting steel plate is placed on the vertebral body with zero incisura, the close segment of the vertebral body does not need to be exposed, the operation incision is small, the number of cut ribs is smaller, patients recover better, and the supporting steel plate is suitable for a minimally-invasive operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anterior thoracolumbar spine adjustable zero-notch minimally invasive support plate. Background technique [0002] Currently, in spinal decompression surgery for the treatment of disc herniation or bone spurs, it is necessary to perform stability reconstruction after resection of part of the vertebral body, that is, to restore the normal mechanical support state of the spine. The mesh fusion cage made of titanium alloy is a new type of bone graft substitute used in spinal surgery abroad in recent years. It has a wide range and can be used in conjunction with various internal fixators. It is a very promising spinal reconstruction technology. It has been confirmed that the anterior reconstruction of titanium mesh can restore the height and curvature of the spine, thereby restoring the normal biological performance of the spine, and has good biocompatibility and combinat...
