Fixed connection, the central axis of fixing screw is in a certain angle with the centrage of screwed hole.
The bottom surface of described screw slots is an inclined plane, and the centrage of described screwed hole is mutually perpendicular to described inclined plane.
Described fixing screw includes head of screw, shank of screw and is arranged on the company between described head of screw and described shank of screw
Meeting portion, the diameter of described connecting portion is more than the diameter of shank of screw, and the afterbody of connecting portion and shank of screw is equipped with screw thread and screw thread spiral shell
To identical, connecting portion is threadeded with screwed hole.
Described head of screw has been internally formed quincunx groove, is provided with cross groove in described quincunx groove.
Described blade plate two ends are provided with kirschner pin hole.
The bottom surface of described blade plate is provided with sucked type structure.
Described angle is 0 °～45 °.
This utility model advantage: fixing screw is located on blade plate by the inclined plane of screw slots, does not limit to vertically connecing
The direction of hone lamella, can multi-faceted regulate, and to adapt to blade plate initial stage predeterminated position, then can position smoothly after confirming position and angle
And connect fixing, and make clinical operation motility be greatly improved, clinic is easy to install reliably.

Detailed description of the invention
If Fig. 1 is to shown in 7, a kind of internal fixation device for department of orthopaedics, it includes blade plate 1 and fixing screw 2, and blade plate 1 includes
One end face and one for connecting the bottom surface of the injury of the bone, blade plate 1 be provided with along its length screw slots 11 and pressurized tank 12 and
Alternately, screw slots 11 are provided with screwed hole 111 for screw slots 11 and pressurized tank 12, and pressurized tank 12 is provided with pressurization hole 121, hole of pressurizeing
121 is bar hole, and fixing screw 2 is connected through screwed hole 111 and the injury of the bone are fixing, the central axis of fixing screw 2 and blade plate 1
Bottom surface in a certain angle.
Further, the bottom surface of screw slots 11 is an inclined plane 112, and the centrage of screwed hole 111 is mutual with inclined plane 112
Vertically.
Further, fixing screw 2 include head of screw 21, shank of screw 22 and be arranged on head of screw 21 and shank of screw 22 it
