Background
In recent years, the success rate of surgery is remarkably improved for most congenital heart diseases including complex severe diseases, and for some complex congenital heart diseases, the key to more urgently improve the success rate and long-term curative effect of surgery is to adopt the degree of constriction of pulmonary artery by the constriction band to be adapted to the cardiovascular system of a patient. Traditional ring contracts area and puts for ordinary dacron area or silicon rubber have the special ring of woven mesh belt to contract area, and the two is all inelastic, can't extend the expansion, in case confirm the ring degree of contracting, is difficult to change the condition adjustment according to patient's hemodynamics. The part adopts adjustable ring contracts the ware and only can supply the regulation under the infant operation in-process and for opening the chest state, and the difficult operation of area regulation mode in narrow and small chest cavity and tissues such as fragile blood vessel, and these devices can't open chest state, intraoperative after closing the chest, postoperative early and long-term measurement ring contracts in-band vascular wall pressure simultaneously, also can't be according to patient vital sign and guardianship, treatment and inspection conditions such as supersound, breathing machine of postoperative internal diameter of contraction.
After the previous related girth belt is fixed, the matching degree of early stage infant blood vessel girth and infant heart lung hemodynamics change belt depends on clinical manifestation or ultrasonic evaluation. However, clinical evaluation is indirect evaluation, and depending on clinical experience of an evaluator, ultrasound often fails to meet evaluation standards due to delayed chest closing of a patient after an operation, incision accessories, use of a respirator, pulmonary congestion or infection, thoracic deformity and the like, and is prone to cause incision and thoracic cavity infection of the patient. Even if the ring shrinkage band is judged to be unmatched with the actual need accurately in the early stage after the operation, the doctor can only let patient's cardiopulmonary viscera adapt to the unmatched condition gradually through medicine and instrument treatment or solve this problem through early thoracotomy, this also leads to patient's death rate to promote by a wide margin when having reduced treatment. After the infant successfully discharged from the hospital grows and develops, the blood volume of the original band cannot meet the requirements of body movement and development through the ring-shrink belt, and the inner diameter of the ring-shrink belt may need to be increased properly. The previous proposal needs an open chest operation to dissociate the adhered tissues around the original ring-contracting belt and remove the ring-contracting belt to carry out ring-contracting again, or an artificial vascular B-T anastomosis operation is carried out at other positions to increase the blood flow in the lung. These solutions are highly traumatic and risky, and also still do not allow accurate control of the blood flow into the lungs after secondary surgery.
