Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with attached drawing, to the present invention into
Row is further described.
Embodiment 1
As shown in Figure 1, 2, 3, zero back gauge steel plate of anterior cervical vertebrae undercut mark disclosed in the present embodiment, includes the plate body of anatomical form
1 and screw 4,1 top and bottom of plate body are all provided with there are two the hole 2 for being used for mounting screw 4, and hole 2 has a notch, the hole 2 of upper end
Gap opened in the top edge of plate body 1, the gap opened in the hole 2 of lower end is in the lower edge of plate body 1.Preferably, hole 2 is four
/ tri- circular holes.
The present embodiment mesoporous 2 is equipped with internal thread, has the external screw thread 6 being adapted to internal thread on the nut of screw 4.Such as Fig. 4 institutes
Show, external screw thread 6 is fine thread, and the screw thread on the screw rod of screw 4 is coarse-pitch thread 5.There is observation window 7 in 1 center of plate body, and doctor is facilitated to see
The case where examining bone is convenient for observation in art and postoperative.
Plate body 1 thickens at hole 2, ensures the intensity of steel plate.Preferably, plate body 1 thickens at both ends, and the thickness at this is
The thickness of 2mm-3mm, rest part are 1.5mm.Observation window 7 is set to thin part, and observation window 7 is rectangle, length of side 6mm-
7mm；1 width of plate body is 14mm-16mm, and the distance between the same end holes Liang Ge 2 are 10mm.1 length of plate body is arranged as required to
For single-unit length, two section length or more piece length.As shown in Figure 2,3, plate body side view, vertical view and upward view are
Arch designs.As shown in figure 5, screw 5 and plate body 1 are at obtuse angle, such as 110 °.It is equipped with locking spring plate in 5 tail portion of screw, can be prevented
Screw exits.
Embodiment 2
