Description

Device for assisting reduction of limb fracture

Technical Field

The invention belongs to the technical field of medical instruments, and particularly discloses a device for assisting limb fracture reduction.

Background

Fracture refers to the continuous complete or partial breakdown of bone structure. It is common to children and the elderly, and occurs in the middle-aged and young. The patients usually have fracture at a certain part, and a few have multiple fractures, and after timely and proper treatment, most patients can recover the original functions, and a few patients can have sequelae with different degrees. The fracture of the long bones of the limbs is the most common fracture form, and due to the traction of muscles and the movement of limbs after fracture, the short deformity and the rotation deformity are easy to generate, thereby influencing the life quality of patients; the immediate reduction after fracture has important significance for fracture treatment, the fracture reduction is generally reduced by operation or manipulation, and the operation reduction has the biggest advantage of achieving anatomical reduction and has the defects of increasing local injury, being not beneficial to fracture healing and having potential infection risk; the manual reduction has the advantages of small damage, easy fracture healing, simple method and no need of complex equipment, thus being widely used. The resetting method comprises the following steps: local anesthesia is firstly carried out to eliminate the pain of the patient; the assistant holds the proximal end of the fracture, and the surgeon holds the distal end to perform counter traction, and the patient can reset after the muscle is tired and relaxed after a few minutes. According to the specific situation, it is usually done by reverse folding, rotating, lifting, pressing, splitting bone, and correcting.

At present, some fracture reduction instruments exist, mostly adopt a threaded sleeve structure, and because lower limb muscle strength is very strong, the rotary sleeve is very hard, and can also cause the slope at rotatory in-process, is unfavorable for the stability of tractor, and the device is fixed and is adjusted not nimble after the broken bone, and the degree of difficulty is great, leads to the range of reseing to adjust the precision and receives influence and restriction, pulls unstably, and the precision that resets is low. Meanwhile, the existing fracture repositor is generally suitable for being used in units such as hospitals and the like, and a device for timely and effectively repositioning and fixing the long bones of the limbs on the emergency treatment site is not provided.
