Description
Technical field
This utility model relates to a kind of device for spreading, relates in particular to a kind of delayed sternal closure breastbone device for spreading, belongs to medical instruments field.
Background technology
Congenital heart disease is commonly encountered diseases, frequently-occurring disease in infant.China's congenital heart disease rate is up to 7-8 ‰.According to statistics, China about has 15-20 ten thousand to increase patient newly every year, and wherein Complexed Congenital Heart Disease infant accounts for 30%-40%.In congenital heart disease diagnosis and treatment center, Jiangsu Province amount for surgical about 1200 examples/year, success rate of operation is more than 98%.But Various Complex congenital heart disease, as the transposition of great vessel, pulmonary atresia, Single Cardiac Ventricle etc., because its hemodynamics and normal children are completely different, generally, age is all less than normal, operation is hit too large, and operative mortality, complication rate are all higher, remain the huge challenge that pediatric cardiac surgery faces.
These Complexed Congenital Heart Disease infants, often due to preoperative poor heart function, cardiopulmonary bypass time is long, and operation wound is large and affect therapeutic effect, and success rate of operation is subject to certain restrictions.Critical diseased children can be helped to spend the acute stage of postoperative myocardial edema, Lower cardiac function smoothly, particularly important.
Delayed sternal closure, as heart peri-operation period important technology and measure, can save the life of many infants.Have two kinds of modes clinically at present: one be operation terminate rear maintenance breastbone open wide, be referred to as constitutional delayed sternal closure; Another kind is rear closedown breastbone of having performed the operation, if the unstable rule that circulates reopens breastbone, is referred to as Secondary cases delayed sternal closure.The indication of delayed sternal closure: 1. postoperative cardiac function is not good, cardiac dilatation, unbecoming with mediastinum volume size, blood pressure drops after breast is closed in examination, atrial pressure rises, heart beating is unable and the performance such as arrhythmia.2. the needs of heart chamber auxiliary pump are installed.3. apply artificial blood vessel or Conduit valved homograft, breastbone compressing pipeline, causes blood circulation unstable.4. breastbone dysplasia, pigeonbreast, to compressing heart in the breastbone of indent, affect heartbeat.
This important surgical method of delayed sternal closure, extensively confirmed in the clinical practice of at home, external Surgical treatment of congenital heart diseases to be to operate and to be effective, part critical diseased children can be helped to spend the peri-operation period of blood circulation instability smoothly, strive for valuable time and chance for further treating and processing, thus save the life of numerous critical Complexed Congenital Heart Disease infant.The suitable delayed sternal closure Sternal distraction device can selected for pediatric cardiac surgery doctor is still lacked at present in congenital heart disease operation treatment field.The method that current pediatric cardiac surgery is conventional is: 1. directly sew up skin edge; 2. adopt plastic injection syringe cutting rear distraction breastbone, edge and sternum suture are fixed, and sew up skin edge after under free skin; 3. on the basis of 2, do not sew up skin edge, operation rubber gloves is cut into the shape of needs, sews up with skin edge.First method is because breastbone is without support, and can not maintain the state that breastbone opens, Thorax volume is not fixed, fall flat.Latter two method, because of needs scene processing equipment, can extend operating time, and the equipment of on-the-spot processing is lack of standardization, and fixing difficulty is large, is easy to slippage.
Therefore, how a kind of Sternal distraction device for delayed sternal closure is provided, make its structure simple, there is less volume, easy to use, space, thoracic cavity can be increased, avoid heart compression, be convenient to again the stitching of surgical wound, reduce the risk infected, shorten operating time, become the major issue that pediatric cardiac surgery field is urgently to be resolved hurrily.
