(II) technical scheme
The utility model discloses a following technical scheme realizes: the utility model provides a four unification of thighbone distal end cut bone micromatic setting, including regulating plate, regulation hole one and regulation hole two, one side shaping has in the regulating plate regulation hole one, regulation hole one has four, regulation hole one by the regulating plate center outwards presents ascending structure, adjacent two the difference of vertical height between the regulation hole one is 1mm, the opposite side shaping has in the regulating plate regulation hole two, regulation hole two has four, regulation hole two by the regulating plate center outwards presents descending structure, adjacent two the difference of vertical height between the regulation hole two is 1 mm.
Through adopting above-mentioned technical scheme, through regulating plate, ascending structure one and descending structure the design of regulating hole two for the doctor can set up appropriate amount fine tuning hole on patient's thighbone, and the doctor of being convenient for realizes the fine setting of four times one section hone lamella when the operation, with the convenient measurement that adapts to different patients and cuts the bone volume, has avoided the loaded down with trivial details that four unification osteotomy plates were selected, has improved the efficiency of operation.
Further, the first adjusting hole and the second adjusting hole are the same in size.
By adopting the technical scheme, the adjustment of the four-in-one bone cutting plate is convenient to realize.
Furthermore, an adjusting handle is welded in the middle of one side wall of the adjusting plate.
Through adopting above-mentioned technical scheme, be convenient for realize the regulation of regulating plate.
Furthermore, a first pin is welded on the other side wall of the adjusting plate, and a second pin is welded on one side of the adjusting plate, which is far away from the first pin.
By adopting the technical scheme, the adjusting plate can be conveniently fixed through the first pin and the second pin.
(III) advantageous effects
Compared with the prior art, the utility model, following beneficial effect has:
for solving four unification of present thighbone distal end and cutting the bone apparatus when cutting the bone and measuring, can't compromise anterior condyle and back condyle simultaneously, because everybody's individual difference, under unified back condyle cuts the bone volume, everybody anterior condyle cuts the bone volume difference and can select four unification osteotomy boards to the doctor and cause the difficulty, makes the thighbone distal end cut the bone degree of difficulty and increases, reduces the problem that the operation efficiency will, the utility model discloses a design of regulating plate, the structure regulation hole one that rises and the structure regulation hole two that falls makes progress for the doctor can set up proper amount fine tuning hole on patient's thighbone, and the doctor of being convenient for realizes the fine setting of four unification osteotomy boards when the operation, with the convenient measurement of adaptation different patient osteotomy volumes, has avoided the loaded down with trivial details that four osteotomy boards chose, has improved the efficiency of operation.
