Children lower limb single hip herringbone fixing and skin traction device

Abstract

The invention discloses a child lower limb single hip herringbone fixing and skin traction device. The instrument comprises a lower limb fixing plate, and the lower limb fixing plate is worn on a child and tightly attached to the hip and the lower limb below the hip of the child; a foot fixing plate is arranged below the lower limb fixing plate, and pulley supporting rods are fixedly connected to the two sides of the bottom end of the lower limb fixing plate; the bottom end of the pulley supporting rod is rotationally connected with a pulley which is in sliding fit with a lower steel wire rope. One end of the lower steel wire rope extends upwards and is connected with the upper end of the foot fixing plate; the other end of the lower steel wire rope bypasses the pulley, extends upwards and is fixedly connected with the upper steel wire rope through a traction adjusting device; and a weighing device is arranged on the upper steel wire rope. According to the present invention, when one end of the lower steel wire rope is pulled upwards, the lower steel wire rope generates traction force for driving feet to move downwards through the pulley, so that the traction effect on the lower limbs of a child is achieved, and meanwhile the traction force can be accurately controlled through the weighing device.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a single hip herringbone fixation and skin traction device for children's lower limbs. Background technique [0002] As we all know, children, as a special group, love sports, have poor self-protection ability and discrimination ability, and are very easy to cause accidental injury. Femoral shaft fracture is a common lower extremity fracture in children, with an incidence rate of 1.6%. It is mostly caused by falls, heavy objects and traffic accidents. For children aged 8 months to 5 years, femoral shaft fractures whose shortening is greater than 2 cm or whose angle is greater than 30° can be treated conservatively: (1) Use continuous lower limb skin traction for at least 14 days, and change to plaster after callus formation Fixed; (2) Continuous suspension and traction of both lower limbs for 1-2 months. [0003] During the above-mentioned treatment process, the child n...
