Lower limb bone traction device with guiding function

A lower limb bone traction device with a guiding function comprises a U-shaped plate-shaped traction bow, the two ends of the U-shaped plate-shaped traction bow are each provided with a first threaded hole, the two first threaded holes are coaxially formed, each first threaded hole is internally provided with a guiding sleeve, threads are arranged on the outer circumferential face of each guiding sleeve, and the guiding sleeves are connected with the U-shaped plate-shaped traction bow. The guide sleeves are in threaded connection with the first threaded holes, a second threaded hole is formed in the side face of the outer end of each guide sleeve, and a screw is in threaded connection with the interior of each second threaded hole. After the columnar traction bow is changed into the plate shape, the area of the plate plane of the plate-shaped traction bow is large, the plate plane is not prone to distorting and deforming in the front-back direction, the left-right direction and the like, the U-shaped symmetri
