The operation principle and application method of plate 2 are same as above.Twin fixed guide-vane steel plate 2 and intramedullary nail 3 cooperate, twin fixed guide-vane steel plate 2
20 long axis of steel plate body keep consistent with intramedullary nail 3, intramedullary nail 3 realizes that effective fracture site position support is fixed, and passes through
Each first lock screw of twin fixed guide-vane steel plate 2 is close to intramedullary nail 3 and wears cortex to fix, i.e., steel plate body 20 pass through set it is special
Twin fixed guide-vane screw (or perhaps Bidirectional locking is realized in each corresponding first lock screw work of each pilot hole cooperation for determining angle
Screw) rotation is controlled to intramedullary nail 3 and strengthens the effect of support, and then realize the accurate positionin fixation at shaft fracture position with
And anti-rotation and anti-axial direction it is unstable, further enhance effective support for shaft fracture, stablize, aids fracture position is accurate
It determines that position is fixed, has effectively ensured the stability after shaft fracture reset.
It should be pointed out that specific embodiment described above can make those skilled in the art that the present invention be more fully understood
It creates, but do not limit the invention in any way is created.Therefore, although this specification referring to the drawings creates the present invention with embodiment
It makes and has been carried out being described in detail, it will be understood by those skilled in the art, however, that still can modify to the invention
Or equivalent substitution, in short, the technical solution of all spirit and scope for not departing from the invention and its improvement, should all contain
It covers among the protection domain of the invention patent.
