Preferably, the shape of described tooth is bottom surface is the leg-of-mutton triangular pyramid of curved surface or three terrace with edges, and described triangular pyramid or three terrace with edges by bottom surface be curved surface rhombus, the identical rectangular pyramid in four sides or truncated rectangular pyramids be split to form along its plane of symmetry.
Preferably, the angle of the angle a that the cross section that the bottom surface of described tooth can be locked hole is divided equally is 6-18 °.
Preferably, the angle of the angle a that the cross section that the bottom surface of described tooth can be locked hole is divided equally is 10-14 °.
Preferably, the inwall of described lock hole is provided with four row, six row or the above even column tooth of six row, and tooth is structure symmetrically, and between two often relative row teeth, structure is identical.
Preferably, plate body comprises integrated blade plate one and blade plate two, and the shape of described blade plate one and blade plate two all adapts with skeleton shape.
After adopting technique scheme, this utility model has following good effect:
(1) lock hole on multi-shaft locking blade plate of the present utility model and screw are not be spirally connected by screw thread, but be provided with even column tooth at the inwall of lock hole, and the shape of tooth is rectangular pyramid or truncated rectangular pyramids or triangular pyramid or three terrace with edges, screw thread on screw and tooth interlock and lock, even if when screw is crooked, also can well and lock hole assemble, in actual use, doctor can select proper angle to lock fracture portions according to patients with fractures's situation, improves the work efficiency of doctor greatly;
(2) angle of the angle a that the cross section that the bottom surface of tooth can be locked hole is divided equally is 6-18 °, this angle design, when ensureing that screw coordinates with lock hole, decreasing the resistance that screw bears, in use using minimum power to reach lock-screw object;
(3) lock hole in this utility model is round table-like, and along with progressively screwing of screw, the diameter of lock hole reduces gradually, coordinating of be more convenient for screw and lock hole, further helps having screwed of screw of tilting.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Embodiment 1
As Figure 1-3, be multi-shaft locking blade plate of the present utility model, comprise plate body 1, this plate body 1 comprises integrated blade plate one 11 and blade plate two 12, and the shape of blade plate one 11 and blade plate two 12 all adapts with skeleton shape.
Blade plate one 11 and blade plate two 12 are equipped with at least one lock hole 2, and lock hole 2 is in round table-like.In use, screw screws in from the large one side of the cross section of lock hole 2 multi-shaft locking blade plate, the little one side of the cross section of lock hole 2 compared to the large one side of cross section closer to human body.The inwall of lock hole 2 is provided with at least two row teeth 3, and often row tooth 3 is along the bearing of trend order arrangement of the centrage of lock hole 2, and be staggered between adjacent two row teeth 3 non-cross overlap, is convenient to screw thread on screw and interlocks with tooth 3 and lock.Tooth 3 symmetrically structure, between two often relative row teeth 3, structure is identical.
The shape of tooth 3 is tetrapyamid shape, also can be quadrangular frustum pyramid shaped, the bottom surface of described rectangular pyramid or truncated rectangular pyramids is curved surface rhombus, four sides are identical, and the inwall of bottom surface laminating lock hole 2, the number of degrees of the angle a that the cross section that the bottom surface of tooth 3 can be locked hole 2 is divided equally are 6-18 °, and preferably, the angle of a is 10-14 °.This kind of profile design of tooth 3, when ensureing that screw coordinates with lock hole 2, decreasing the resistance that screw bears, in use using minimum power to reach the object of lock-screw.
The one side of fitting with human body of plate body 1 is provided with arcuate groove, and making between multi-shaft locking blade plate and skeleton can not note be attached completely, and blood circulation promoting, makes fracture site recover faster.
In the present embodiment, the inwall of lock hole 2 is provided with four row teeth 3, tooth 3 symmetrically structure, and the structure of two relative row teeth 3 is identical.Be appreciated that the columns of tooth 3 can also be two row, six row or the above even column of six row, all can reach the application target identical with four row.
Embodiment 2
As illustrated in figures 4-5, in the present embodiment, be with the difference of embodiment 1, the shape of tooth 3 is different.The shape of tooth 3 is bottom surface is the leg-of-mutton triangular pyramid of curved surface or three terrace with edges, and the inwall of described bottom surface laminating lock hole 2, described triangular pyramid or three terrace with edges by bottom surface be curved surface rhombus, the identical rectangular pyramid in four sides or truncated rectangular pyramids be split to form along its plane of symmetry, two triangular pyramids or three terrace with edges can be spliced into rectangular pyramid in embodiment 1 or truncated rectangular pyramids.
In use, the human fracture that fitted by plate body 1 locates multi-shaft locking blade plate of the present utility model, and screw screws in from the lock hole 2 of diverse location respectively, in screwing operations, do not need the angle adjusting screw, can ensure the perfect cooperation of screw and lock hole 2 yet, alleviate the use burden of doctor.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain that this utility model requires.
