Description
技术领域technical field
本实用新型涉及医疗器械技术领域，具体地说，是一种可调节式肺动脉环缩装置。The utility model relates to the technical field of medical equipment, in particular to an adjustable pulmonary artery constriction device.
背景技术Background technique
先天性心脏病(简称先心病)是先天性畸形中最常见的一类，约占各种先天畸形的28％，指在胚胎发育时期由于心脏及大血管的形成障碍或发育异常而引起的解剖结构异常，或出生后应自动关闭的通道未能闭合(在胎儿属正常)的情形。我国先心病发生率约为0.8％，每年新增患儿约15万人。目前，先心病已成为婴幼儿死亡及致残的主要原因，严重影响人口的素质和生存质量。随着小儿心脏外科技术的不断提高，各类先心病的治疗均得到了发展。对于某些肺血流过多伴有肺动脉高压的先心病，尚不能进行一期外科纠治，或者病情严重不能耐受复杂手术，或因年龄限制不宜早期行根治手术，此时肺动脉环缩术作为姑息性手术可为日后手术创造条件。目前，肺动脉环缩术应用较为成熟，作为一种姑息性手术在保护肺血管床、实施心室功能锻炼、完成复杂先心病的分期矫治方面具有不可缺少的重要作用。Congenital heart disease (abbreviated as congenital heart disease) is the most common type of congenital malformation, accounting for about 28% of various congenital malformations. Structural abnormality, or the failure of a channel that should close automatically after birth (which is normal in the fetus). The incidence rate of congenital heart disease in my country is about 0.8%, and about 150,000 new children are born every year. At present, congenital heart disease has become the main cause of infant death and disability, seriously affecting the quality of the population and quality of life. With the continuous improvement of pediatric cardiac surgery technology, the treatment of various congenital heart diseases has been developed. For some congenital heart diseases with excessive pulmonary blood flow and pulmonary hypertension, primary surgical correction cannot be performed, or the condition is too severe to tolerate complex surgery, or early radical surgery is not suitable due to age restrictions, at this time pulmonary artery constriction As a palliative operation, it can create conditions for future operations. At present, the application of pulmonary artery constriction is relatively mature. As a palliative operation, it plays an indispensable and important role in protecting the pulmonary vascular bed, implementing ventricular function training, and completing the staged correction of complex congenital heart disease.
肺动脉环缩术所选择的环缩材料一般有丝线、Gore-Tex人造血管和含Teflon的涤纶带等，其环缩手术效果类似。但是，因为肺动脉环缩的程度无法随时控制，环缩过松则起不到环缩目的，直接影响手术效果，甚至还有环缩材料移位等情况发生，而环缩过紧则影响氧合，对血流动力学影响亦大，乃至危及生命。据文献报道，肺动脉环缩术仍是一种风险较高的姑息性治疗手段，其手术死亡率为5％～20％。The constriction materials selected for pulmonary artery constriction generally include silk thread, Gore-Tex artificial blood vessel, and polyester tape containing Teflon, etc., and the constriction effect is similar. However, because the degree of constriction of the pulmonary artery cannot be controlled at any time, the purpose of constriction will not be achieved if the constriction is too loose, which will directly affect the surgical effect, and even the displacement of constriction materials may occur, while too tight constriction will affect oxygenation. , has a great impact on hemodynamics, even life-threatening. According to reports in the literature, pulmonary artery constriction is still a high-risk palliative treatment, with a operative mortality rate of 5% to 20%.
此外，还有一种电动遥控的可调节式环缩器。虽然该环缩器可以随时调控环缩的松紧程度，但是其操作繁琐，价格昂贵，仅仅出现在国外临床试验当中，还未大规模推广应用。In addition, there is an adjustable ring compressor with electric remote control. Although the ring constrictor can adjust the tightness of the ring at any time, its operation is cumbersome and expensive. It only appears in clinical trials abroad and has not been widely used.
因此，亟需一种结构简单、操作方便且价格低廉的可调节式肺动脉环缩装置，可有望解决环缩过松过紧问题而可以达到随时按需调节的目的，更有利于提高此类患儿的术后生存率及生活质量。Therefore, there is an urgent need for an adjustable pulmonary artery constriction device with simple structure, convenient operation and low price, which is expected to solve the problem of too loose and too tight the constriction and can achieve the purpose of adjusting on demand at any time, and is more conducive to improving the effectiveness of such patients. Postoperative survival rate and quality of life of infants.
