Spine system is made of titanium alloy, according to different age and body parts, spine system design forφ4.0mm•φ7.0mm spine screw and φ4.5mm-φ6.0mm rod. The 4.5mm-φ5.0mm rod system applied to children fractures, orthopaedic internal fixation.Especially curved rod basically conform to the physiological curvature of human spine design, can be convenient operation.Hollow long arm pedicle screw can be minimal invasive operation.
There are two types of spinal interbody fusion devices: block fusion devices and lamellar fusion devices. The main body of the fusion cage is made of polyether ether ketone (PEEK) polymer material conforming to the YY / T0660-2008 standard, and the material level is LT1. The developing needle in the fusion machine is made of TC4 titanium alloy material that complies with GB / T13810-2007.
