Fixing and straightening device for forearm fracture and application method of fixing and straightening device

Abstract

The invention discloses a fixing and straightening device for forearm fracture and an application method of the fixing and straightening device. The fixing and straightening device comprises a forearm fixing assembly and an upper arm fixing assembly, wherein the forearm fixing assembly comprises a pair of first fixing plates which are oppositely arranged and a pair of second fixing plates which are oppositely arranged; the spacing between the pair of the first fixing plates and the spacing between the pair of the second fixing plates are adjustable; the upper arm fixing assembly is movably connected with the forearm fixing assembly through a pair of connecting assemblies, and comprises a pair of third fixing plates which are oppositely arranged and of which the spacing is adjustable; a fixing rod is arranged between each first fixing plate and the corresponding third fixing plate; and one end of each fixing rod is arranged at the side end of the corresponding first fixing plate in a sliding manner, and the other end of each fixing rod is hinged to the side end of the corresponding third fixing plate. According to the fixing and straightening device provided by the invention, affected limbs are be prevented from being impacted by external force; and in the using process, the spacing between the fixing plates can be regulated according to the swell degree of the affected limbs, so that the forearm is fixed, and the situation that the affected limbs are subjected to pressure injury is also avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular, the invention relates to a forearm fracture fixation and correction device and a method for using the same. Background technique [0002] At present, plaster is often used in orthopedics to fix forearm fractures after reduction, promote healing, prevent pathological fractures, and correct congenital deformities. After the fracture, the affected limb will be swollen. Sometimes the doctor visits earlier, and the swelling of the limb is not obvious. After the plaster external fixation, the swelling will continue to increase, which will make the plaster, which is originally moderately elastic, become too tight, resulting in cyanosis, chills or feeling of pain in the extremity. Severe pain and numbness can cause pressure sores, skin necrosis, or blood circulation disorders and nerve compression in severe cases. At this time, the plaster will need to be removed and re-fixed. In the later ...

AI Technical Summary

Problems solved by technology

In the later stage, as the swelling of the limbs decreases, the plaster may loosen, and the immobilization effect of the plaster will be greatly reduced.

However, most of the forearm fracture protectors that can be used to replace plaster are used to fix the forearm with a splint, and then Velcro is used to adjust the inner diameter of the protector to adapt to the thickness of the affected limb. Any cushioning effect will cause secondary damage to the affected limb due to external force, and it is usually necessary to lift the forearm through the shoulder strap, making this kind of fracture protector very troublesome to use
