Sternum supporting frame for delaying closing chest

Abstract

The invention relates to a sternum support frame with delayed closing of the sternum, which is provided with a bracket, the bracket is arc-shaped, the chord length is 3-5cm, and the radian is 10-40 degrees; the two ends of the bracket are respectively provided with a slot in the shape of a tiger's mouth , the two side groove surfaces of the card slot are perpendicular to the arc surface of the bracket; the card slot is provided with an upper support arm and a lower support arm, and the upper support arm is shorter than the lower support arm; the upper support arm is shorter than the lower support arm; A threading hole is respectively arranged on the arm and the lower support arm; the support frame is made of metal. Its advantages are: the card slot can firmly hold the split sternum on both sides; the threading hole can be easily sutured and fixed, further preventing the support frame from slipping to the patient's head or feet and slipping to the inside and outside of the sternum; the radian design of the bracket is reasonable, and can be Keep the incision at a suitable width; the overall structure is strong and durable; the integrated design is convenient for use and manufacturing.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a sternum support frame for delayed closing of the sternum. Background technique [0002] Congenital heart disease is a common and frequently-occurring disease in infants and young children. The incidence rate of congenital heart disease in my country is as high as 8‰, which has become the first cause of death of children under five years old. According to statistics, there are about 150,000 new patients every year in my country, of which patients with complex congenital heart disease account for about 30%-40%. At present, about 30,000 to 40,000 children in China receive congenital heart disease operations each year, and the number of operations in the heart center of Shanghai Children’s Medical Center alone exceeds 3,000 cases per year. The success rate of ventricle and other operations is over 90%. With the advancement of medical science and technology, many simple c...

AI Technical Summary

Problems solved by technology

The above-mentioned first method is often unable to effectively maintain the open state of the sternum because the sternum is not supported, and the latter two methods will prolong the operation time because of the need for processing equipment, and the delayed chest closure equipment that is simply reprocessed has irregular shapes and is difficult to fix. It is easy to slip off, so it is often difficult to meet the requirements of stably and reliably fixing the sternum, which has caused great trouble to clinical work, and more importantly, increases patient trauma, prolongs hospital stay, increases medical expenses, and even directly endangers the lives of children

Therefore, there is an urgent need for a convenient, stable and reliable delayed sternum support frame, but there is no report about this type of support frame at present.
