Fractures of thighbone, acetabulum, pelvis, tibia, fibula and hip joint are common fractures in clinic, surgical treatment is the first treatment method, and before intramedullary nail fixation and bone plate fixation are carried out, the two ends of a fracture part need to be reset, butted and fixed. Traction is an important means for reducing fracture and recovering the length of lower limbs. In traction therapy, bone traction is a method of passing through bone with a steel needle or a traction forceps, and directly passing through the bone to reach an injury part by using traction force, so as to play the roles of reduction, fixation and rest. The advantages are that: the device can bear larger traction weight, has smaller resistance, can effectively overcome muscle tension and correct deformity caused by fracture overlapping or joint dislocation; secondly, the affected limb is convenient to inspect after traction; thirdly, the traction force can be properly increased, so that blisters, pressure necrosis or circulatory disturbance of the skin can not be caused; and fourthly, fixing by matching with a splint, and strengthening the function exercise of the affected limb under the condition of keeping the fracture end from moving, so as to prevent the joint from being stiff and the muscle from shrinking and promote the fracture healing. The disadvantages are that: firstly, a steel needle directly penetrates into bone through skin, and if the treatment is improper, infection at the needle eye can be caused; secondly, the inaccurate needle inserting position can damage the joint capsule or the nerve vessel.
The bone traction is a means which needs to be mastered by an orthopedist, so that the bone traction needs to be simulated in the medical teaching process, but the traditional orthopedics medical teaching aid has some defects, for example, although various orthopedics models such as crystal bones and pvc-made simulated bones can enable medical students to know the bone structure more intuitively, the bone traction operation directly on the bone model cannot achieve the effect of real teaching simulation; however, some models can only be used for simulating whether the bone traction operation steps are standard and whether the traction mode is correct, and whether a steel needle or a traction forceps accurately passes through the optimal traction position on the bone cannot be determined in the process of simulating the bone traction operation.
