Embodiment
The utility model is further described below in conjunction with the accompanying drawings.Embodiment of the present utility model includes but unlimited
In the following example.
Embodiment 1
As shown in figure 1, a kind of femoral prosthesis handle for femur size trochanteric fracture, include the femoral shaft prosthese of strip
7, the upper end of femoral shaft prosthese 7 is provided with the greater trochanter end 5 and lesser trochanter end 9 matched with the big lesser trochanter of femur, and the femoral shaft is false
Body 7 is provided with neck of femur prosthese 2 between greater trochanter end 5 and lesser trochanter end 9, and neck of femur prosthese 2 is connected with femoral head vacation
Body 1, the femoral shaft prosthese 7 are located at greater trochanter end 5 and are provided with two screwed holes 3 and multiple greater trochanter sewing holes 4, the femur
Dry prosthese 7 is located at lesser trochanter end 9 and is provided with multiple lesser trochanter sewing holes 8.
The present embodiment is in use, femoral shaft prosthese 7 is inserted in the pulp cavity of femur 10, its upper end greater trochanter end 5 and lesser trochanter
End 9 matches with the big lesser trochanter with femur 10, and fixing screws then are squeezed into femur 10 by the greater trochanter of femur 10 by screwed hole 3
It is fixed, then threaded by greater trochanter sewing hole 4 and the suture of greater trochanter end is fixed on the tendon soft tissue of femur 10, finally again will
Lesser trochanter end threads suture by lesser trochanter sewing hole 8 and fixed, and the big lesser trochanter of femur 10 can be fixed.
The femoral prosthesis handle of the present embodiment coordinates with femoral bone cavitas medullaris, and fracture is supported by greater trochanter end 5 and lesser trochanter end 9
Greater trochanter and lesser trochanter, and fixed by screwed hole 3, greater trochanter sewing hole 4 and lesser trochanter sewing hole 8, so as to for stock
The support of bone size trochanteric fracture, which is fixed, to be used, and the femoral shaft prosthese 7 of strip can increase the contact with femoral bone cavitas medullaris
Area, increase the stability of prosthesis handle.
In the present embodiment, the surface of femoral shaft prosthese 7 is provided with thread groove 6.Thread groove 6 can increase femoral shaft
