Description

Breastbone external fixer

Technical field

This utility model relates to technical field of medical instruments, particularly a kind of breastbone external fixer.

Background technology

Fracture of the sternum is often caused by severe thoracic injury complicated, mainly because powerful violence directly acts on caused by sternal region or extruding, how due to traffic accident deceleration wound or directly impact injury cause, also can by extrude and blunt directly hits and causes, account for about 5% of thoracic trauma, mostly caused by vehicle accident.Fracture mostly occurs at the body of breastbone, and majority is the fracture of non-displacement, transecting type.Wherein the most common with sternal body fracture, account for 76.5%, be secondly presternum fracture, account for 9.0%, presternum, body intersection fracture accounts for 8.5%, is often associated with fracture of rib, hemopneumothorax, extremity fracture etc.

Because the stability of front thoracic wall is affected after fracture of the sternum, thorax causes the broken ends of fractured bone to brake with respiratory movement, and produce violent local pain, cause breathing limited, airway secretions increases, and cause the generation of restricted obstructive ventilatory difficulty and pulmonary complication, and fracture site is unstable, can the broken ends of fractured bone be aggravated hemorrhage, even can cause increasing the weight of of associated injury.Therefore, emergency treatment carry out in early days local fix, effectively alleviate or eliminate pain and fracture end displacement, be fracture of the sternum treatment key link

Breastbone is spongy bone, ligament, muscle are organized in attachment more, and obtaining the support of costicartilage, clavicle, Peripheral blood is for abundant, and self-healing ability is very strong, and fracture of the sternum is stable mostly, therefore, though for without the fracture of the sternum be obviously shifted or displacement is stable, usually get involved without the need to operation, treatments such as only need taking to lie up, pain relieving braking, pectoral girdle are fixed, encourage expectoration, protect from infection, and prognosis bona.And breastbone is obviously shifted, cause thorax unstable, even cause nonunion, person need select operative treatment as early as possible to occur dyspnea, but also needs local to take fixation for treatment before surgery, to alleviate the pain of patient, stablizes the state of an illness.The expectant treatment of current fracture of the sternum mainly selects effective External fixation, but there is no desirable External fixation method at present, traditional method has fracture site sandbag pressing, adopt pectoral girdle pressurized fixation for treatment, but all there is extenal fixation to be easily shifted, fixing uncertain, restriction movement of thorax, affects the deficiencies such as respiratory function; Also have the chest external fixer of employing " BABAKA " to treat, same exist shortcomings such as using inconvenient, impact sleep.

Utility model content

The purpose of this utility model is to provide a kind of breastbone external fixer, can to breast bonebone foldingeffectively fix, fixing be not shifted, it is effective, it is right to alleviatemovement of thorax restriction, the function that ensures respiration is normal, reduces pulmonary complication, and after prevention breastbone, the generation of hematoma and progress, improve patient comfort.
