Titanium Applications - Orthopedics: Spinal Fusion Apparatus (interbody Fusion apparatus)

Titanium alloy fusion device

According to relevant literature records, the authors of this paper took the titanic-coated PEEK fusion apparatus and titanium alloy fusion apparatus as the research objects, respectively, by simulating the vertebral space environment, using the same method, the two were implanted and observed. Most of the coating on the surface of the titanium-coated PEEK fuse has been worn off during the tapping process. There was no debris and wear in the process of tapping the titanium alloy fusion device.

Titanium alloy materials have begun to re-enter the historical stage.

Material: ASTM F67 Titanium Bar;

Manufacturing method: Machining + special pits;

Shape: box shape, kidney shape, bullet head shape, hollow, surrounded by bone grafting window, surface with pits or jagged non-slip structure.

The fifth generation of 3D printing fusion

The emergence of 3D additive manufacturing technology has made 3D printing implants quickly applied to various medical fields, and metal 3D printing interbody fusion devices are gradually available. 3D printing technology is mainly divided into SLM selective laser melting and EBM electron beam melting, etc. The unique bionic porous structure has laid its unique position in the medical field.

Yesino Titanium 1

Material: titanium alloy powder; Titanium Grade 23

Manufacturing method: SLM selective laser melting /EBM electron beam melting;

Shape: Rectangular shape, kidney shape and other surfaces with different radians/angles can better fit the vertebral endplate, and conform to the normal physiological curvature of the human body after implantation; A variety of titanium bionic porous structures are conducive to bone growth.

Spinal fusion device (interbody fusion device) depending on the material, according to the processing method, additive or reduced material, approach method, surgical site, need to carry out clinical trials.

Sigma Medicine and spine surgery, orthopedics across the country have a lot of trials going on.
