Follow-up fracture traction reduction fixator

1. The present utility model relates to the field of medical devices, in particular to a follow-up fracture traction reduction fixer.

Background technique:

2. In trauma orthopedics, bone distraction is the use of the principle of force and reaction force in mechanics, through the traction of gravity, acting on the affected limb, relieving the tension and retraction of the soft tissue at the fracture and dislocation, and reducing the fracture or dislocation. , to achieve the purpose of treatment.

3. In the development of hundreds of years, orthopedic surgery has undergone tremendous development. Through continuous improvement, the existing traction mechanism mainly uses the traction method of traction arch combined with metal bone needle. The nails are driven at the ends of the limbs and maintain their tension with a tension bow, which requires a pulley device attached to a counterweight to pull the tension bow. In this way, in order to maintain the overall stable traction state, the traction frame must be fixed to the hospital bed, and the tension traction bow should always be connected with the counterweight and pulley device.

4. Since the pulley device cannot move after being fixed, it restricts the patient's daily activities and is not conducive to the patient's going out for examination. Long-term bed rest after traction can cause bedsores, respiratory complications, malnutrition, muscle atrophy, joint stiffness and excessive traction. not connect etc. Moreover, in traditional traction, the fracture end is pulled by a heavy object to achieve the reduction effect. In this case, the fracture end may be displaced into an angle due to the change of the patient's bed position, and it is difficult to achieve continuous constant traction. Ineffective traction until the fractured end stimulates the local skin for a long time, resulting in redness, swelling, blisters, and ulceration of the skin, which affects further treatment, prolongs the waiting time for surgery, and increases treatment costs.
