Figure 1 shows that the structural representation of the blade plate of the embodiment of the present invention, as shown in Figure 1, blade plate has a top side face 1, for contacting the bottom side 2 of bone and more than two screw hole 3, screw hole 3 is communicated with through blade plate from top side face 1 to bottom side 2, screw hole 3 is arranged along two longitudinal axis on blade plate, further, as shown in Figure 2, screw hole 3 is from an angle of vertical line skew of blade plate top side face.Particularly, as shown in figure as left in Fig. 2, the screw hole being positioned on the longitudinal axis of blade plate left side is offset equal angular left from the vertical line of blade plate top side face; As shown in figure as right in Fig. 2, the screw hole being positioned on the longitudinal axis of blade plate right side is offset equal angular to the right from the vertical line of blade plate top side face.
Wherein, the angle that screw hole 3 is offset can be 5 °-7.5 °.
Particularly, as shown in Figure 1A, screw hole 3 is arranged along two longitudinal axis on blade plate, and n+1 screw hole on different longitudinal axis, and is offset an angle from the vertical line of blade plate top side face from n screw hole in the opposite direction.Such as n screw hole is offset an angle left from the vertical line of blade plate top side face, n+1 screw hole is offset equal angular to the right from the vertical line of blade plate top side face.
As shown in Figure 3, screw hole of the prior art is generally the vertical line setting along blade plate top side face, and in the time adopting screw fixation bone fracture plate, fixing surface of bone is long-pending is only 31 like this, and the frictional force between screw and bone contact surface is limited; As shown in Figure 2, the screw hole of the present embodiment is from an angle of vertical line skew of blade plate top side face, and fixing surface of bone amasss as dash area 22, compare dash area 31, the present embodiment increases the fixing bone volume of screw, has increased the hold of screw, thereby improves the fixing stability of blade plate.
Further, screw hole 3 can be the overlapping hole of screw hole or slide pressurization hole and screw hole.
Further, the two ends of the blade plate of the present embodiment gradually attenuation and head end are arc, and proximal edge punishment is furnished with circular hole, and circular hole is used for inserting Kirschner wire, can before blade plate being fixed with screw, pre-fix blade plate.
The blade plate of the present embodiment is simple in structure, screw hole on blade plate is arranged on blade plate in the mode of intersection angulation, like this in the time using screw fixation bone fracture plate, can surely fix by more than enough flat lock, increase the volume of controlling of screw, increase the hold of screw, thereby make the fixing more stable of blade plate, be beneficial to the healing of patient's fracture.
The blade plate of the present embodiment can be applied in dissimilar fracture.Below in conjunction with different classification of fracture, the blade plate of the present embodiment is described further.
