Abstract

The invention relates to the field of medical tools, in particular to an orthopedic fixing device which comprises a limb fixing table, a drilling hole fixing device, a bilaterally movable fixing device and two pulley fixing devices. The left end and the right end of the drilling hole fixing device are slidably connected at the left end and the right end of the limb fixing table, the bilaterally movable fixing device is fixedly connected in the drilling hole fixing device, the two pulley fixing devices are in clearance fit with the left end and the right end of the limb fixing table, and the upper ends of the two pulley fixing devices are engaged with the left end and the right end of the drilling hole fixing device. The orthopedic fixing device has the advantages that fracture bones can bedrilled when fracture fixation is implemented, multi-angle adjustment of a drilling device is guaranteed, multi-angle and all-directional drilling of the bones can be achieved by combining fracture positions of patients, bone nails are drilled into the bones, and the drilling success rate is guaranteed.

Description

technical field [0001] The invention relates to the field of medical tools, in particular to an orthopedic fixation device. Background technique [0002] Most of the work in orthopedics is to use bone nails and brackets to perform fracture fixation on broken or fractured bones.
