On 60, suitable for being fixed on the ontology 60 on osteotomy limbs；Guide groove 61, is adapted for insertion into osteotome, treats osteotomy limbs
Osteotomy again adjusts the tilt angle of Osteotomy to be measured.
As deformation design scheme, assist osteotomy part 6 that can also have multiple, when auxiliary osteotomy part 6 is mounted on connection structure 5
After upper, the guide groove 61 on each auxiliary osteotomy part 6 has different tilt angles relative to the plane where contact surface 21, such as
1 °, 2 °, 3 °, 4 °, 5 °, 6 ° or -1 °, -2 °, -3 °, -4 °, -5 °, -6 ° etc., according to the difference of actual measurement angle, selection is inclined
The most suitable auxiliary osteotomy part 6 of rake angle.
As preferred design, the fixation hole 63 is equipped with multiple groups on the ontology 60, to adapt to different thicknesses
Limbs.
The application method of the utility model Posterior Slope Angle of Tibial Plateau degree measuring device is as follows:
Firstly, the contact surface 21 of plate 2 is placed on Osteotomy, and make its fitting contact；The finger of indicator at this time
Needle is directed toward a direction；
Then, adjusting angle degree identification piece 3 makes a certain scale of angle number identification piece 3 and has above-mentioned Osteotomy
The center of the ankle of the side limbs is aligned；
Finally, the number of division on the angle number identification piece 3 that reading pointer 12 indicates, the number of division with above-mentioned a certain scale
Between angle difference, the hypsokinesis angle of tibial plateau osteotomy surface as to be measured.
If Posterior Slope Angle of Tibial Plateau degree is undesirable, connection structure 5 can be further used and auxiliary osteotomy part 6 is right
Tibial plateau carries out osteotomy again, complies with hypsokinesis angle requirement, method particularly includes:
The socket block 51 of connection structure 5 is set on handler 31, rotary motion handle 31, the angle for indicating pointer 12
The difference between number of division and above-mentioned a certain scale on number identification piece 3 meets the requirements, and then passes through the fixed osteotomy of fixation hole 63
Auxiliary member 6 removes indicator 1, plate 2, angle number identification piece 3, connection structure 5, passes through guide groove 61 using osteotome
Osteotomy again is carried out to tibial plateau, can be obtained the Tibial osteotomy plane for more accurately meeting hypsokinesis angle number requirement.
It should be pointed out that when in order to avoid osteotomy auxiliary member 6 fixed by fixation hole 63, the inclination of osteotomy auxiliary member 6
Angle changes, and fixation hole 63 is internal thread hole, and fixing screws are fixed on the shin bone of patient after rotating through fixation hole 63.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes among the protection scope created still in the utility model.
