Problems solved by technology

3. Application of artificial blood vessels or homologous tubes with valves, sternum compression tubes, causing unstable blood circulation
The first method does not achieve the desired effect because the sternum is not supported and cannot maintain the open state of the sternum. The chest volume is not fixed.
The latter two methods require on-site processing of equipment, which will prolong the operation time, and the on-site processing equipment is not standardized, making it difficult to fix and easy to slip off

Embodiment 1

[0023] Example 1 : see figure 1 , figure 2 , a device for delaying the closing of the sternum and sternum, the distraction device includes a base part and an upper part of the sternal groove, the base part includes an arch plate part 1 and a lower part of the sternal groove, wherein the arch plate part 1 is arranged in the middle, and the lower part of the sternal groove is symmetrical It is arranged at both ends of the arch part 1 . The overall structure of the device is compact and ingenious in design, the sternum is firmly fixed, the operation is simple, and the patient is less injured. Moreover, children of different ages have different lengths of spreaders, which vary from person to person according to needs. The lower part of the sternal groove includes the lower leaf 2 of the sternal groove and two lower connection points 6, and the upper part of the sternal groove includes a spring 12, a cross bar 10, two upper connection points 7, the upper leaf 3 of the sternal ...

Embodiment 2

[0024] Example 2 : see figure 1 , figure 2 , as an improvement of the present invention, there is a lined arc-shaped iron sheet 14 in the sternal groove. The sternal groove is lined with an arc-shaped iron sheet 14, which makes the sternum not directly contact the upper and lower connection parts of the sternal groove and the spring, but directly contacts the iron sheet without edges and corners, which reduces the damage of the sternum and the pain of the child. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Embodiment 3

[0025] Example 3 : see figure 1 , figure 2, as an improvement of the present invention, the arcuate part of the base part is integrated with the lower part of the sternal groove to make the spreader more stable. The arched part is 5-10 mm wide, preferably 8 mm, and 2-2 mm thick. 4mm is preferably a steel plate of 3mm, and has a physiological radian, and the radian is 10°-40°, and the length of the arch plate is 2cm-10cm. Children with different ages and different sternal distraction requirements. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Abstract

The invention relates to a sternum expanding device with the sternal closure delaying function. The sternum expanding device is characterized by comprising a base part and a sternum groove upper part; the base part comprises an arch board part and sternum groove lower parts; the arch board part is arranged in the middle, and the sternum groove lower parts are symmetrically arranged at the two ends of the arch board part. The device is compact and ingenious in overall structural design, accurate in positioning, simple in operation, short in operation time and small in damage to sick children, expanders of many types are adopted, and the device is suitable for the sick children of different ages and different types and wide in application range.

Description

Technical field [0001] The present invention involves an open device, which specifically involves a delayed device for turning the chest and skeleton, belonging to the field of medical device. Background technique [0002] Congenital heart disease is a common disease in infants and young children.The incidence of congenital heart disease in my country is as high as 7-8 ‰.According to statistics, there are about 150,000 to 20,000 patients in my country each year, of which 30%-40%of children with congenital heart disease.Jiangsu Province's congenital cardiac disease diagnosis and treatment center surgery is about 1200 cases / year, and the surgical success rate is more than 98%.However, a variety of complexity congenital heart disease, such as large vascular dislocation, pulmonary artery atresia, and ductive ventricular. Because its blood flow dynamics is completely different from normal children, under normal circumstances, the age is small, the surgery is too large, the surgery is ...
