Auxiliary reduction device for distal radius fracture

Abstract

The invention discloses an auxiliary repositor for distal radius fracture. The auxiliary repositor comprises an L-shaped elbow joint supporting plate, a horizontal supporting plate, a slideable waist joint supporting plate and a hand sliding fixing handle. An arm of a patient is subjected to elbow flexion by 90 degrees and then is put on the L-shaped elbow joint supporting plate, and an upper arm and a front arm are fixed on the L-shaped elbow joint supporting plate through an upper arm bandage and a front arm bandage respectively; the patient holds the hand sliding fixing handle with fingers, and a hand is fixed by a self-adhesion bandage; an adjusting bolt is rotated, and the slideable waist joint supporting plate moves away to achieve the effect of fracture site pull-out; then the hand sliding fixing handle is moved in an arc-shaped sliding groove, so that the arm reaches a palmer flexion or dorsiflexion angle needed for fracture stabilization; a fixed bolt is screwed, so that the hand sliding fixing handle is fixed. The auxiliary repository has a simple structure, is low in manufacturing cost, convenient to operate, stable in traction in the restoration process, and ideal in restoration effect, avoids redisplacement had, and meanwhile, reduces the working intensity and difficulty of medical staff.

Description

technical field [0001] The invention relates to a medical appliance, in particular to an auxiliary resetter for distal radius (Colles) fractures. Background technique [0002] At present, the fractures of the distal radius (Colles) are all reset by manual traction by medical staff. However, due to physical problems of medical staff, the traction strength is often insufficient and the reduction cannot be completed. During the reduction process, medical staff need to repeatedly touch the fractured end to confirm the traction Therefore, it is difficult to maintain a stable traction force, which often leads to redisplacement of fractures; X-ray perspective is required to confirm the reset effect during reset, which can easily cause a large number of medical staff and patients to be injured by radiation; after the reset is completed, use When the plaster and splint are fixed, the broken end of the fracture cannot maintain the position after reduction, and the fracture may redispl...
