It relates to a superficial implant implant.

In general, the spine is composed of 33 bones to support the body and to protect the spinal nerve, 7 cervical vertebrae in the neck, 12 thoracic vertebrae in the chest, lumbar spine in the lower back It consists of five, five sacral vertebrae located in the pelvis and four coccyx located in the tail.

The spine is composed of a number of independent vertebrae as described above, each of which is connected by joint nodes, with soft discs (or bites) filled between each joint. This type of spine buffers and supports various postures and protects organs in the body.

The spine is a complex structure composed of various anatomical elements, and provides the body with flexibility and resilience.

The vertebrae are composed of vertebrae, and each vertebral body has a cylindrical shape.

Opposite sides of the vertebral bodies adjacent to each other are connected to each other and at the same time separated by intervertebral discs (or discs) made of fibrocartilage.

In addition, the vertebral bodies are connected to each other by complex ligament tissues that interact to limit excessive movement and provide stability.

The vertebrae comprise a thick side portion called the lateral mass. Each outer bulge includes facets on its upper and inner sides.

The lumbar condyle of the single vertebra is combined with the medial condyle of the next adjacent vertebra. This joint combination is called the intervertebral joint.

A stable spine is important to prevent incapacitating pain, progressive deformity and / or neurological compromise.

Current surgical methods of treating ligament injuries of the spine include removal of facet joint capsules and arthroplasty of the joints.

In this case, in treating the instability of the lower cervical spine, a screw is usually used that extends through the outer bulges of the adjacent vertebrae.

The problem involved in this approach is that damage to the spinal nerve can occur when screwing into the lateral ingot.

First, the skin of the part where the spine is located is incised, and the incision cuts the skin to a length that allows the implant of the superficial protrusion of the present invention to be inserted into the human body.

A bone block (unsigned) is installed between the ridges of the vertebral body with lesions and the adjacent ridges with the skin incision.

The material of the bone block (Bone block) is made of autologous bone or dead body bone or artificial bone, which uses only safe products recognized by the Korea Food and Drug Administration, as well as using sterilized products to prevent infection during surgery.

A separate mechanism is provided in the upper hook hole 16 and the lower hook hole 25 formed in the upper locking member 10 and the lower locking member 20 in the state where the bone block is positioned between the upper protrusion and the upper protrusion. The upper ring 15 of the upper catching member 10 is positioned on the upper projection using the fixed mechanism, and the lower ring 24 of the lower catching member 20 is positioned on the other adjacent projection. Let's do it.

When the lower ring 24 is positioned, as shown in FIG. 3B, the lower catching member 20 is pulled out and rotated to one side of the upper catching member 10 to adjust the length and the position thereof to catch the superfine protrusion. To lose.

The locking using the mechanism fixed to the upper hook hole 16 and the lower hook hole 25 so that the upper locking member 10 caught on the top projection and the lower locking member 20 caught on the adjacent top projection close to each other. Reduce the gap between the member 10 and the lower locking member 20.

When the gap between the upper locking member 10 and the lower locking member 20 is narrowed, the upper latch formed on the upper body 10 by the lower latch 22 formed on the lower body 21 of the lower locking member 20. The lower body 20 is lifted slightly so as to be hooked to 12.

The lower body 21 prevents the lower body 21 from rotating in the upper body 11 by the anti-rotation jaw 14 formed in the upper body 11 while being introduced into the upper body 11. .
