背景技术Background technique
先天性心脏病是婴幼儿中的常见病、多发病。我国先天性心脏病发病率高达7-8‰。据统计，我国每年约有15-20万新增病人，其中复杂性先天性心脏病患儿占30%-40%。江苏省先天性心脏病诊疗中心手术量约1200例/年，手术成功率为98%以上。但是多种复杂性先天性心脏病，如大血管错位、肺动脉闭锁、单心室等，因其血流动力学与正常儿童完全不同，一般情况下，年龄均偏小，手术打击太大，手术死亡率、并发症发生率均较高，仍然是小儿心脏外科面临的巨大挑战。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 7-8‰. According to statistics, there are approximately 150,000-200,000 new patients each year in my country, of which children with complex congenital heart disease account for 30%-40%. The Jiangsu Provincial Congenital Heart Disease Diagnosis and Treatment Center operates about 1,200 cases per year, with a success rate of over 98%. However, a variety of complex congenital heart diseases, such as great vessel dislocation, pulmonary atresia, single ventricle, etc., because of their hemodynamics are completely different from normal children, in general, the age is relatively young, the surgical blow is too large, and the surgical death The incidence rate and complication rate are high, and it is still a huge challenge for pediatric cardiac surgery.
这些复杂性先天性心脏病患儿，往往由于术前心功能差，体外循环时间长，手术创伤大而影响治疗效果，手术成功率受到一定的限制。能否帮助危重患儿顺利度过术后心肌水肿、心功能低下的急性期，尤为重要。Children with complex congenital heart disease often have poor preoperative cardiac function, long extracorporeal circulation time, and large surgical trauma, which affect the therapeutic effect and the success rate of the operation is limited to a certain extent. It is particularly important to help critically ill children successfully pass the acute stage of postoperative myocardial edema and low heart function.
延迟关胸作为心脏围手术期一项重要技术和措施，可以挽救许多患儿的生命。目前临床上有两种方式：一种是手术结束后保持胸骨敞开，称之为原发性延迟关胸；另一种是手术完成后关闭胸骨，如果循环不稳定则重新打开胸骨，称之为继发性延迟关胸。延迟关胸的适应症：1.术后心脏功能不佳，心脏扩大，与纵隔容积大小不相称，试关胸后血压下降、心房压上升、心跳无力及心律失常等表现。2.安装心室辅助泵的需要。3.应用人造血管或同种带瓣管道，胸骨压迫管道，引起血液循环不稳定。4.胸骨发育不良、胸骨畸形，内凹的胸骨内向压迫心脏，影响心脏跳动。Delayed chest closure is an important technique and measure in the perioperative period of the heart, which can save the lives of many children. At present, there are two clinical methods: one is to keep the sternum open after the operation, which is called primary delayed chest closure; the other is to close the sternum after the operation, and reopen the sternum if the circulation is unstable, which is called primary delayed chest closure. Secondary delayed chest closure. Indications for delayed chest closure: 1. Poor heart function after surgery, heart enlargement, disproportionate to mediastinum volume, blood pressure drops, atrial pressure rises, weak heartbeat, and arrhythmia after trial chest closure. 2. The need to install a ventricular assist pump. 3. The application of artificial blood vessels or homogeneous valved pipes, the sternum compresses the pipes, causing unstable blood circulation. 4. Sternal dysplasia, sternal deformity, the concave sternum compresses the heart inwardly, affecting the beating of the heart.
延迟关胸这一重要的外科方法，在国内、国外先天性心脏病外科治疗的临床实践中被广泛证实是可操作而且是行之有效的，可以帮助部分危重患儿顺利度过血液循环不稳定的围手术期，为进一步的治疗和处理争取了宝贵的时间和机会，从而挽救了众多危重复杂性先天性心脏病患儿的性命。目前在先天性心脏病手术治疗领域尚缺乏可供小儿心脏外科医师选择的适宜的延迟关胸胸骨撑开器。目前小儿心脏外科常用的方法为：1.直接缝合皮缘；2.采用塑料注射针筒裁剪后撑开胸骨，边缘与胸骨缝合固定，游离皮下后缝合皮缘；3.在2的基础上不缝合皮缘，手术用橡胶手套裁剪成需要的形状，与皮缘缝合。第一种方法因胸骨无支撑，不能维持胸骨张开的状态，胸腔容积不固定，没有达到预期效果。后两种方法因需要现场加工器材，会延长手术时间，而且现场加工的器材不规范，固定难度大，易于滑脱。Delayed chest closure, an important surgical method, has been widely proven to be operable and effective in the clinical practice of surgical treatment of congenital heart disease at home and abroad, and it can help some critically ill children successfully overcome blood circulation instability During the perioperative period, valuable time and opportunities were gained for further treatment and treatment, thus saving the lives of many critically ill children with complex congenital heart disease. At present, in the field of surgical treatment of congenital heart disease, there is still a lack of suitable delayed closing sternal distractors for pediatric cardiac surgeons to choose. At present, the commonly used methods in pediatric cardiac surgery are: 1. Directly suture the skin edge; 2. Use a plastic injection syringe to cut and stretch the sternum, suture and fix the edge to the sternum, and suture the skin edge after freeing the subcutaneous tissue; 3. On the basis of 2. Suture the skin edge, cut the surgical rubber gloves into the desired shape, and sew them to the skin edge. The first method does not achieve the expected effect because the sternum is not supported and cannot maintain the open state of the sternum, and the chest volume is not fixed. The latter two methods will prolong the operation time due to the need for on-site processing equipment, and the on-site processing equipment is not standardized, it is difficult to fix, and it is easy to slip.
因此，如何提供一种用于延迟关胸的胸骨撑开器，使其结构简单，具有较小的体积，方便使用，既能增加胸腔空间，避免心脏受压，又便于手术创口的缝合，降低感染的风险，缩短手术时间，成为小儿心脏外科领域亟待解决的重要问题。Therefore, how to provide a sternal spreader for delaying chest closure, which has a simple structure, a small volume, is convenient to use, can increase the space in the chest cavity, avoid heart pressure, facilitate the suturing of surgical wounds, and reduce the The risk of infection and shortening the operation time have become important problems to be solved in the field of pediatric cardiac surgery.
