Background
The distal femur osteotomy is one of the most important steps in the total knee replacement surgery, and the anatomical structure and the degree of wear of the articular surface of the femur are different from patient to patient, so that the accurate osteotomy positioning by the distal femur osteotomy positioning device is very important for the distal femur osteotomy. Currently, in total knee replacement surgery, a distal femur osteotomy positioning device is used for positioning osteotomy by inserting an intramedullary positioning rod into a femoral medullary cavity and matching the distal femur osteotomy positioning device. And adjusting the valgus angle through the distal femur osteotomy positioning device according to the positioning of the intramedullary positioning rod and the femoral medullary cavity to perform distal femur osteotomy, wherein the term "valgus angle" refers to the angle between the body axis and the considered channel. In the case of a femur, the valgus angle is the angle formed between the mechanical and anatomical axes of the patient; in the case of a distal femoral resection locator, the valgus angle refers to the angle between the axis of the distal femoral resection locator and the corresponding channel;
the conventional positioning tool is inconvenient to conveniently adjust the eversion angle and the positioning distance when in use, so that the optimal operation effect cannot be achieved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the conventional positioning tool is not convenient to adjust the eversion angle and the positioning distance when in use, thereby not reaching the defect of the optimal operation effect and providing the positioning tool for cutting the distal femur.

Preferably, the one end of rotation axis is connected with the angle fixed plate, and the outside cover of angle fixed plate is equipped with reset spring, and reset spring can drive the angle fixed plate and reset.
Preferably, the main body is provided with a first main body positioning pin and a limiting pin, the first main body positioning pin is connected with the limiting pin, and the main body is further provided with a second main body positioning pin.
Preferably, one end of the fixing block is provided with a button, the other end of the fixing block is provided with a knob, and the knob is matched with the button.
Preferably, be provided with the button spring between button and the sliding block, the button spring can drive the button and reset.
Compared with the prior art, the utility model has the advantages of:
the utility model discloses can effectually fix a position thighbone distal end osteotomy when using, and the distance that just can be convenient regulation location and the angle that turns up promote the effect of operation.
