The teeth portion of rack 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 it is single
The teeth portion of side gear can inscribe vestige in intercondylar ridge Inner edge, and the vestige represents 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 femur and tibial prosthesis is demonstrate,proved, avoids that the situation that excessive osteotomy, angular deviation or prosthese hit occurs, reduces trouble
Person's pain, accelerates speed of wound healing.
As preferred：Detachable handle is additionally provided with the arc location-plate.Using above structure, pass through handle
Stablize whole orienting locator, it is ensured that device is fitted in the centre position of femur Inner condyles, and 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.Simple in construction using above structure, installation is reliable, is easy to tear open
Unload.
As preferred：The handle is truncated cone-shaped, and the diameter of the handle first end is less than the straight of the end of 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 rack are integrally formed.Using above structure, structural strength is high, makes
With reliable and stable.
As preferred：The arc location-plate and unilateral rack use metal material.Using above structure, structural strength
Height, use are reliable and stable.
As preferred：The a height of 1mm of teeth portion, tooth pitch 1.5mm.Using above structure, the tooth of unilateral rack was both ensured
Portion can inscribe vestige in intercondylar ridge Inner edge, and and can reduces the operation wound of patient.
Compared with prior art, the beneficial effects of the utility model are：
It is novel using tibial plateau inner edge osteotomy orienting locator provided by the utility model, structure, it is easy to accomplish, it is overall
Small volume and less weight, easy to use, doctor can accurately determine the direction of the vertical osteotomy in tibial plateau inner edge, make to cut outgoing direction and femur
Prosthese is axially consistent, ensures the correct placement of femur and tibial prosthesis, avoids that excessive osteotomy, angular deviation or prosthese shock occurs
Situation, reduce patient pain, accelerate speed of wound healing.

Embodiment
The utility model is described in further detail 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 rack 2, the radian of the unilateral rack 2 and the radian phase of arc location-plate 1
Together, the teeth portion 2a of the unilateral rack 2 is used to inscribe vestige in intercondylar ridge Inner edge.The arc location-plate 1 and unilateral rack 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 rack 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 rack 2, tooth pitch are
1.5mm, vestige can be inscribed in intercondylar ridge Inner edge by both having ensured the teeth portion 2a of unilateral rack 2, and and can reduces the operation wound of patient.
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 that shape location-plate 1 connects 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 by other connected modes such as embedded and position
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
