Transverse intersection.In 19 position of notch, locks and be formed with a gap between wire rod 18 and shin bone pad prosthese 12.When shin bone pads prosthese 12
When installation to tibia support prosthese, the lug on tibia support prosthese can be caught in the gap, so that shin bone pad prosthese 12 and shin
Connection between bone prosthese is more firm.
Card slot 32 is additionally provided in 31 lower part of rear end of shin bone pad prosthese 12.The hanging platform of card slot 32 and tibia support prosthese cooperates,
Shin bone pad prosthese to be securely fixed on tibia support prosthese.
Here, left back condyle 3, right postartis 4 and gasket concave surface 14,15 are arranged to: for the femur of multiple and different dimensions
Condyle prosthese and shin bone pad prosthese, and the position that the position and right postartis that left back condyle is contacted with gasket concave surface are contacted with gasket concave surface is permanent
It is fixed, to provide condyle of femur and the more match selections of gasket in the case where guaranteeing optimal contact surface.A kind of specification as a result,
Lateral femoral condyle prosthesis can simultaneously and plurality of specifications shin bone pad prosthese cooperation, doctor can according to the actual conditions of patient select and
The shin bone of lateral femoral condyle prosthesis best match pads prosthese.The comfort of success rate of operation and patient is improved as a result,.
For the application by using specific lateral femoral condyle prosthesis and tibia support prosthesis assembly, a kind of lateral femoral condyle prosthesis of specification can
Can be selected simultaneously with lateral femoral condyle prosthesis most according to the actual conditions of patient with the pad prosthese cooperation of the shin bone of plurality of specifications, doctor
Good matched shin bone pads prosthese.The comfort of success rate of operation and patient is improved as a result,.
Figure 10-14 shows the tibia support prosthese 20 of an embodiment according to the present invention.Tibia support prosthese 21 has main body 22
With the shank 23 extended downwardly out from main body.Preferably, shank 23 is integrally extended downwardly from main body.Main body 22 is for connecting shin
Bone pads prosthese (not shown).Shank 23 is for being inserted into human tibia proximal medullary cavity.
As shown in Figure 10, main body 22 is plate-like.There is the anti-spin-block 24 of protrusion in the middle part of the top surface of main body 22.Anti- spin-block 24
Top surface is plane.Anti- spin-block 24 pads the recesses fit on prosthese with corresponding shin bone, and it is opposite that shin bone pad prosthese can be effectively prevented
It is rotated in tibia support prosthese.
The outer rim 25 of main body is protruded relative to the top surface of main body 22.The outer wall of the outer rim 25 of main body 22 is arc surfaced.This reality
It applies in example, the outer wall of the outer rim 25 of main body 22 is made of the multistage cambered surface of different-diameter.The top of a part of outer rim 24 is also set
There are the spaced multiple lugs 26 laterally protruding from the inner wall of outer rim 25.Lug 26 is used for and the lock on shin bone pad prosthese
Alignment material 18 cooperates, and shin bone pad prosthese is securely fixed on tibia support prosthese.Locking wire rod can be tens of thousands of by that can be subjected to
Secondary fatigue test is made without the material of damage.
The side indent opposite with lug 26 of main body 22.Main body 22 is additionally provided with hanging platform 28.Hanging platform 28 is located at and lug 26
It is at the top of opposite side outer rim and laterally protruding from the inner wall of outer rim.Hanging platform 28 is located at anti-24 left and right sides of spin-block.It was installing
Hanging platform 28 can be inserted in Cheng Zhong, one end of shin bone pad prosthese, and the other end is locked in main body 22 by lug 26 and locking wire rod.This
In application, locking wire rod, the anti-spin-block of hanging platform and middle part constitute the locking mechanism of the application, effectively reduce the generation of fine motion
Rate, to reduce the abrasion of knee-joint prosthesis.
As depicted in figs. 11-12, the two sides of shank 23 are equipped with strengthening wing 29.The strengthening wing 29 of two sides is on a different plane.
This strengthening wing 29 can effectively enhance the intensity of tibia support prosthese, reduce the probability of happening of fine motion, and be conducive to tibia support
Prosthese is inserted into human tibia proximal medullary cavity.
In the application, it is preferable that tibia support prosthese is integrally formed.
