The edge of position plate side is provided with unilateral tooth bar, and the radian of the unilateral tooth bar is identical with the radian of arc location-plate, described unilateral
The teeth portion of tooth bar is used to inscribe vestige in intercondylar ridge Inner edge.
Using above structure, doctor holds handle, and whole orienting locator is inserted into patient's knee space, then will suffer from
Person's knee joint is gradually lifted in the dynamic process for stretching position from flexing position, because single-end is higher by arch section thus single
The teeth portion of side gear can inscribe vestige in intercondylar ridge Inner edge, and the vestige is to represent the straightforward bone direction of tibial plateau Inner marginal lappets, from
And doctor can accurately determine the direction of the vertical osteotomy in tibial plateau inner edge, make section outgoing direction axially consistent with femoral prosthesis, protect
The correct placement of card femur and tibial prosthesis, it is to avoid the situation that excessive osteotomy, angular deviation or prosthese clash into occurs, trouble is reduced
Person's pain, accelerates speed of wound healing.
As preferred：Detachable handle is additionally provided with the arc location-plate.Using above structure, by handle
Stablize whole orienting locator, it is ensured that device is fitted in the centre position of femur Inner condyles, handle is detachable, is conveniently replaceable.
As preferred：One end that the handle is connected with arc location-plate has external screw thread, in the arc location-plate
The screwed hole being adapted with the external screw thread is provided with outer wall.Using above structure, simple structure installs reliable, is easy to tear open
Unload.
As preferred：The handle is truncated cone-shaped, and the diameter of the handle first end is straight less than the end of the handle second
Footpath, the handle first end can be connected with the arc location-plate.Using above structure, it is easy to doctor to hold operation.
As preferred：The arc location-plate and unilateral tooth bar are integrally formed.Using above structure, structural strength is high, makes
With reliable and stable.
As preferred：The arc location-plate and unilateral tooth bar use metal material.Using above structure, structural strength
Height, using reliable and stable.
As preferred：The a height of 1mm of teeth portion, tooth pitch is 1.5mm.Using above structure, the tooth of unilateral tooth bar was both ensured
Portion can inscribe vestige in intercondylar ridge Inner edge, and the operation wound of patient can be reduced again.
Compared with prior art, the beneficial effects of the invention are as follows：
The tibial plateau inner edge osteotomy orienting locator provided using the present invention, structure is novel, it is easy to accomplish, it is overall compact
Light, easy to use, doctor can accurately determine the direction of the vertical osteotomy in tibial plateau inner edge, make to cut outgoing direction and femoral prosthesis
It is axially consistent, it is ensured that the correct placement of femur and tibial prosthesis, it is to avoid the feelings that excessive osteotomy, angular deviation or prosthese clash into occur
Condition, reduces patient pain, accelerates speed of wound healing.

Fig. 4 is the structural representation of handle.
Specific embodiment
The invention will be further described with accompanying drawing with reference to embodiments.
As shown in FIG. 1 to 3, a kind of tibial plateau inner edge osteotomy orienting locator, including arc location-plate 1, described
The edge of the side of arc location-plate 1 is provided with unilateral tooth bar 2, the radian of the unilateral tooth bar 2 and the radian phase of arc location-plate 1
Together, the teeth portion 2a of the unilateral tooth bar 2 is used to inscribe vestige in intercondylar ridge Inner edge.The arc location-plate 1 and unilateral tooth bar 2 one
It is body formed, it is easy to technique to manufacture, and the two uses metal material, the integrally formed arc location-plate 1 and unilateral tooth bar 2
It is of different sizes, to adapt to condyle of femur of different sizes.The a height of 1mm of teeth portion 2a of the unilateral tooth bar 2, tooth pitch is
1.5mm, both having ensured the teeth portion 2a of unilateral tooth bar 2 can inscribe vestige in intercondylar ridge Inner edge, and the operation wound of patient can be reduced again.
As shown in Figure 1 to 4, detachable handle 3, the handle 3 and arc are additionally provided with the arc location-plate 1
One end of the connection of shape location-plate 1 has external screw thread 3a, is provided with the outer wall of the arc location-plate 1 and the external screw thread 3a
Adaptable screwed hole, the handle 3 also can be removably mounted on the arc and position by other connected modes such as embedded
On the outer wall of plate 1, the handle 3 can arrange in pairs or groups various sizes of arc location-plate 1.The handle 3 is truncated cone-shaped, the handle
The diameter of 3 first ends is less than the diameter at the end of the handle 3 second, and the first end of the handle 3 can connect with the arc location-plate 1
Connect, be easy to doctor to hold operation.
The course of work of the invention is as follows：
After the conventional approach display condyle of femur of operation and tibial plateau, corresponding size is selected according to the condyle of femur size of measurement
Arc location-plate 1 and unilateral tooth bar 2, handle 3 are arranged on arc location-plate 1, then by arc location-plate 1 and unilateral tooth bar
2 insertion joint spaces, condyle of femur of fitting, it is ensured that arc location-plate 1 is fitted in the centre position of femur Inner condyles will by handle 3
From flexing position be gradually lifted in the dynamic process for stretching position the knee joint of patient by its stabilization, doctor, because unilateral tooth bar 2 compares
Arc location-plate 1 is high, so the teeth portion 2a of unilateral tooth bar 2 can inscribe vestige in intercondylar ridge Inner edge, the vestige is to represent shin bone
The straightforward bone direction of platform Inner marginal lappets, according to disposing prosthese after the vestige osteotomy.
Finally it should be noted that foregoing description is only the preferred embodiments of the present invention, the ordinary skill people of this area
Member on the premise of without prejudice to present inventive concept and claim, can make table as multiple types under enlightenment of the invention
Show, such conversion is each fallen within protection scope of the present invention.
