Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model provides a kind of fracture of neck of femur multi-shaft locking Plate internal fixiation structure, including steel
Plate 1 and many fixing screws, many fixing screws include many first fixing screws being connected with the epimere portion of steel plate 1
2 and many second fixing screws 3 being connected with the middle hypomere portion of steel plate 1, many first fixing screws 2 are used to plant
In the neck of femur for entering femur, many second fixing screws 3 are used in the backbone of implanted femur, so that after steel plate 1 is implanted into
It is fixed.In order that above-mentioned fixed structure can preferably be applied to fracture of neck of femur, the length L1 of the steel plate 1 is 80mm-
120mm, the length L2 of first fixing screws 2 is threaded portion on 95mm-125mm and the distal end of the first fixing screws 2
Length L3 is 22mm-26mm；Therefore, the threaded portion of the distal end of the first fixing screws 2 can all screw in and cross over neck of femur
Fracture line, realizes and is fixed to sliding pressurization.So, the application passes through many first fixing screws 2 and many second fixing screws 3
Steel plate 1 can be implanted into and be fixed on the side of femur, the multi-shaft locking of steel plate 1, steel are realized by many first fixing screws 2
The stability that plate 1 is fixed preferably, and passes through the design of the size of steel plate 1 and the size of the first fixing screws 2 so that the utility model is fitted
For treating fracture of neck of femur, treatment of femoral neck fracture efficiency is improved.
