Abstract
Description

[0002] Tibiofibular fracture is the most common type of long bone fracture, accounting for about 13.7% of all body fractures, and the treatment includes surgical treatment and calcaneus traction. The current traction method is prone to Kirschner wire displacement during traction, and the inclination causes bleeding at the needle eye, and the pressure on the heel causes skin pressure injury, and the change of the traction axis also easily causes the difficulty of fracture end coaptation, fracture end muscle skin injury and a series of complications. In addition, when moving the patient, the affected limb is obviously painful due to the lack of support for traction. Therefore, it is particularly important to improve the traditional traction fixation technology and innovate the traditional traction fixation technology, which cannot relieve the pain of the patient and hinder the promotion of rehabilitation.
[0003] The traditional traction has no any supporting brace, and only the bed tail is shaken to keep the left and right balance by placing towels on the left and right Kirschner needles, and the affected limb is not fixed, which easily causes the change of the traction axis and the difficulty of keeping the affected limb in the neutral position. The defects of the traditional structure are as follows: 1. The Kirschner wire has no support at both ends, the foot of the patient is prone to left and right inclination, bleeding at the needle eye, change of the traction axis, displacement of the traction pin, and compression of the heel skin by the traction arch; 2. The heel has no suspension, which easily causes local skin pressure injury; 3. The affected limb has no support, and the transportation easily causes the dislocation of the fracture end and the aggravation of pain; 4. The angle of the elevated traction limb is difficult to adjust, which affects the effectiveness of traction. CONTENT OF THE UTILITY MODEL
