Embodiment Construction
[0017] see Figure 1~3 , U-shaped elastic piece 1 and two U-shaped cards 2 and two side wings 3 are composed of such as Figure 4 The titanium alloy sheet shown is stamped. see Figure 4 , the elastic sheet 1 is formed by bending part A in the figure, the two U-shaped cards 2 are formed by folding up parts B at both ends, and the two side wings 3 are formed by hollowing out part C and then turning up relatively. In order to avoid external force acting directly on the spinous process and causing spinous process fracture, the root of the U-shaped clip 2 connected to the U-shaped elastic piece 1 is bent into an outwardly arched arc (see figure 2 and image 3 ). see Figure 1~3 and combine Figure 4 , the bolt holes 4 on the two U-shaped cards 2 and the self-tapping screw holes 5 on the two side wings 3 are punched together when they can be stamped, or can be processed separately after stamping.
[0018] according to Figure 1~3 After making the spinous process elastic inter...
