Problems solved by technology
[0005] As mentioned above, in the prior art, there is no clear solution to the above problems clinically, and the traditional empirical operation is still used. There is no accurate method for the osteotomy reduction for children with growth deformity of lower limbs in dealing with rotational reduction. This has brought a lot of inconvenience to the operation, so how to solve the technical problem of low precision of rotation and reset is a topic that those skilled in the art need to study

The invention provides an osteotomy resetting device for femur and tibia. The device comprises a base plate, wherein an adjusting block capable of being turned over front and back and locked is arranged at the front end of the base plate, a centering through hole and at least one first positioning through hole which are parallel are formed in the adjusting block, and an angular scale perpendicularto the base plate is arranged at the back end of the base plate bilaterally; an arc track extending in the scale distribution direction is arranged on the angular scale, the center line of the angular scale is perpendicular to the base plate, a slider capable of moving and positioning along the arc track is arranged on the angular scale, a second positioning through hole is formed in the slider,the center line of the centering through hole and the center line of the angular scale are always in the same plane, and the center line of the second positioning through hole is parallel with one scale mark on the angular scale. The device can accurately guarantee rotary reset angles of femur and is easy to operate.
Description
technical field [0001] The present invention relates to medical instruments for femoral osteotomy and tibial osteotomy, in particular to an osteotomy reduction device for femur and tibia. Background technique [0002] Due to genetic or congenital developmental problems, some children have deformed lower limb growth after birth, which leads to lower limb osteotomy and reduction at a certain age to restore normal physiological structure. [0003] For children with lower extremity growth deformities, the usual surgical treatments include proximal femoral osteotomy reduction, distal femoral osteotomy reduction, proximal tibial osteotomy reduction and distal tibial reduction reduction. It is a combination of four methods. [0004] For some children with severe lower extremity skeletal developmental deformities, conventional osteotomy reduction also requires rotational reduction of the bones. At present, there are many methods for proximal femoral rotation and varus osteotomy, a...
