Reverse skin traction frame for diaphyseal fracture in children and usage method thereof

Abstract

The invention discloses a reverse skin traction frame for diaphyseal fracture in children. The reverse skin traction frame for diaphyseal fracture in the children comprises the following parts which are coaxially arranged: a proximal metaphysis fixing ring, a distal metaphysis fixing ring, and a first telescopic rod; two ends of the first telescopic rod are respectively and fixedly connected withthe proximal metaphysis fixing ring and the distal metaphysis fixing ring; the first telescopic rod has a locking function; a first fixing device is arranged on the proximal metaphysis fixing ring, and comprises a bandage; one end of the bandage is fixedly connected with the proximal metaphysis fixing ring, and the other end of the bandage is connected with the proximal metaphysis fixing ring in an adjustable way; a rotating ring is coaxially arranged inside the distal metaphysis fixing ring, and is in rotating connection with the distal metaphysis fixing ring; a second fixing device is arranged inside the rotating ring, and comprises a skin traction means; and a limiting device is arranged between the distal metaphysis fixing ring and the rotating ring. The reverse skin traction frame fordiaphyseal fracture in the children is capable of simultaneously carrying out pulling in the longitudinal direction and the rotation direction; and moreover, the reverse skin traction frame is convenient to adjust, controllable and precise. Therefore, reset accuracy and maintenance time are improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a reverse skin traction frame for children with bone fractures and its application method. Background technique [0002] Children are naturally active and lack self-protection awareness, coupled with the current frequent traffic accidents and other factors, making children very prone to fractures. According to statistical reports in the literature, before the age of 16, about 1 / 2 boys and 1 / 4 girls have suffered fractures of varying degrees, among which the proportion of bone fractures in limbs is the highest. Research on devices for the treatment of diaphysis fractures in children has great social and economic value. [0003] Children have weak muscle strength, and generally can be reset by traction, and eventually bone healing can be achieved. The currently commonly used "non-invasive" treatment methods are: 1. Continuous skin traction, external fixation with plaster after call...

AI Technical Summary

Problems solved by technology

The currently commonly used "non-invasive" treatment methods are: 1. Continuous skin traction, external fixation with plaster after callus formation, on the one hand, the treatment time is longer (20-30 days in bed), which may lead to skin damage, pressure sores, etc. risk; on the other hand, some social problems may also be caused by the lack of energy of the accompanying staff, parents of the child, and long-term absence from school; 2: The medical staff is purely manual traction, and immediately performs external fixation such as plaster to maintain the reduction , until the fracture heals, but the traction force exerted by pure human traction is uncontrollable, and the strength is affected by the operator's arm strength, and sometimes it may be difficult to reset; and traction reset can only rely on feeling, it is impossible to achieve accurate and effective reset, and it is impossible to achieve anatomical reset
