Definitions
- the invention belongs to the technical field of medical bone tools.
- the instability of the spine occurs after removal of the lumbar disc herniation, or the degenerative lumbar disc disease is unstable, or the ⁇ ", ⁇ " spine slippage, etc., often placed between the vertebral bodies made of metal material
- the internal fixation bracket - Cage for treatment For example, TFC and BAK, which were popular several years ago, have small bearing surfaces, which cause complications such as sinking and slippage after filling the bone, and are inconvenient to install.
- the contact Fusion Cage (such as TELAMON, OIC- Titaniunu OIC- Peek) has been popular. ) replaced.
- the technical solution of the present invention is a lumbar interbody fusion cage, see Fig. 1-2, having a body 4, which is made of fresh and healthy mammalian bones, and is made of fresh and healthy mammalian bones.
- the body 4 has a vertebral shape, and the convex surfaces 1 are respectively disposed on the two sides of the main body 4.
- the two sides of the main body 4 have two or more through holes 3, and the two sides of the main body 4 have a strip-shaped recess 2 at one end of the upper bottom surface. .
- the lumbar interbody fusion cage of the present invention is taken from a fresh and healthy mammal
- the bone is machined into a vertebral shape as described above, see Figure 1.
- the section is in the shape of a 'work' shape, see Figure 2.
- the front end of the body of the cage is smooth and streamlined, so that the implant resistance can be reduced to avoid nerve damage.
- the convex surfaces on the two sides of the body are respectively distributed with the convex teeth 1 and can be engaged with the upper and lower end plates.
- the finished lumbar interbody fusion cage can be used after sterilization.
- the lumbar interbody fusion cage has greater mechanical strength and can be used for support fixation and fusion between the posterior lumbar vertebrae.
- the bone connector made of bone material has non-toxic, non-carcinogenic and non-allergic reactions, has good compatibility with human tissues, can slowly absorb and fuse, and is convenient to install with special tools, so it can be considered as an ideal.
- the finished product of the present invention is put into medical use, the following manner can be followed.
- the cartilage surface of the vertebral body is cleaned, and the cage 2 is clamped by a special cage clamping clamp, and the cage is transversely fed into the intervertebral space. Note that the position is appropriate, and then rotate 90" to make the fusion force
- the beam supports and closely contacts the endplate of the vertebral body, and exits the clamping jaw.
- the structure of the cage with the convex teeth of the cone makes the friction increase and close tightly, so it does not withdraw with the holder.
- the function of the through hole on the cage It is convenient for the autologous bone to grow in the future to facilitate bone fusion.
- a lumbar interbody fixation fracturing machine comprising both the same and xenogeneic bones should fall within the scope of the present invention.
- the invention adopts bone tissue as a material, has no immunogenicity, has high compressive strength, has high mechanical properties and image compatibility, and is suitable for support fixation and fusion between the posterior lumbar vertebrae.
- the invention is convenient to take materials, safe and reliable in quality, and easy to install and apply.
- the replacement of metallic materials with biological materials is in line with the physiological needs of human body.
