Technical Field

The invention relates to the technical field of medical instruments, in particular to a lower limb single hip herringbone fixing and skin tractor for children.

Background

As is well known, children who are special groups like sports have poor self-protection and discrimination capability, and are very easy to cause accidental injuries. Femoral shaft fracture is common lower limb fracture of children, the incidence rate is 1.6%, and the fracture is mostly caused by falling injury, heavy object smashing injury and traffic accidents. Conservative treatment may be taken for fractures of the femoral shaft that are shortened by more than 2cm or have an angulation of more than 30 ° in children of 8 months to 5 years of age: (1) adopting continuous lower limb skin traction for at least 14 days, and fixing by gypsum after callus is formed; (2) the two lower limbs are adopted for continuous suspension and traction for 1-2 months.

In the treatment process, the infant needs to continuously pull the skin for a long time, but the matching degree of children is poor, so that the pulling effect is poor frequently, and the treatment effect is influenced; in addition, the conventional skin traction has the problems that the traction force is inconvenient to adjust, the skin is easy to slip and the like, and a good traction effect cannot be achieved.
