As a further improvement on the present invention, this is used for instep fixing piece interlude in the middle posture supports of total knee replacement
It is fixedly connected on heel fixing piece outer surface, which, which intersects, bypasses instep.
As a further improvement on the present invention, this is used for toe fixing piece and foot in the middle posture supports of total knee replacement
It is that sticky band is made to carry on the back fixing piece.
As a further improvement on the present invention, this be used in the middle posture supports of total knee replacement the toe fixing piece with
The vola fixing piece is connected in a manner of thread gluing.
As a further improvement on the present invention, it is wide to be used for toe fixing piece in the middle posture supports of total knee replacement for this
3cm to 4cm；Vola fixing piece thickness is 1cm to 2cm, including outer layer made of the internal layer and cotton of stainless steel.
As a further improvement on the present invention, this is used for heel fixing piece and vola in the middle posture supports of total knee replacement
Fixing piece is an integrally formed stainless steel part.
As a further improvement on the present invention, which is
22cm to 28cm, is 7cm to 11cm close to toe fixing piece side width, and close to heel fixing piece side, width is
5cm to 8cm.
As a further improvement on the present invention, this is used to be additionally provided with bottom plate in the middle posture supports of total knee replacement, should
Bottom plate is connect with vola fixing piece bottom side, and several sawtooth grooves are provided on the bottom plate,.
As a further improvement on the present invention, this is used in the middle posture supports of total knee replacement further include aluminum alloy material
Manufactured pole, the pole are fixed on bottom base plate.
Middle posture supports of the invention for total knee replacement are used, instep in art can be made to remain neutral body
Position, to assist doctor to determine the lower limb line of force, it is ensured that prosthese is located in the correct line of force, avoids continuous manual change ankle in operation
Position is to determine uncertainty that the lower limb line of force is brought.The present invention holder can disinfection with high pressure steam, facilitate in art and use.
