本发明涉及一种气囊式心脏房间隔扩张圈，属于医护用品技术领域。The invention relates to a balloon-type cardiac interatrial septal expansion ring, which belongs to the technical field of medical supplies.
背景技术Background technique
心脏的房间隔位于左、右心房之间，和室间隔一样与矢状面呈45°，由两层心内膜夹少量心肌和结缔组织构成，厚约1-4mm，卵圆窝处最薄，厚约1mm，目前在所有的需要解决二尖瓣，探查左心房的手术时，需要建立体外循环，心脏停止跳动后，切开房间隔，但是现有的操作中发现，手术的位置较深，难以暴露，目前主要使用拉钩，但是这样的操作方法容易拉裂，暴露困难，需要助手牵拉，阻挡视野，所以现有的手术操作方法还是不够完善。The atrial septum of the heart is located between the left and right atrium. Like the ventricular septum, it is 45° to the sagittal plane. It is composed of two layers of endocardium sandwiching a small amount of myocardium and connective tissue, with a thickness of about 1-4mm. It is the thinnest at the fossa ovalis. The thickness is about 1mm. At present, in all operations that need to solve the mitral valve and explore the left atrium, extracorporeal circulation needs to be established. After the heart stops beating, the atrial septum is cut. However, it is found in the existing operations that the surgical site is relatively deep. It is difficult to expose. At present, retractors are mainly used. However, such an operation method is easy to tear, difficult to expose, and requires an assistant to pull and block the field of vision. Therefore, the existing surgical operation methods are still not perfect.
发明内容Contents of the invention

具体实施方式detailed description
下面结合附图和实施例对本发明作进一步的详细说明。The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
本发明的实施：气囊式心脏房间隔扩张圈，所述心脏房间隔扩张圈由充气扩张圈1和连通管2连接组成，所述充气扩张圈1的中部设置有扩张孔3，在充气扩张圈1上设置有出气孔6，所述连通管2由外部通管4和内部通管5组合而成，所述外部通管4与充气扩张圈1的气囊相连接，所述内部通管5和出气孔6相连接，在外部通管4和内部通管5上设置有充气管7。Implementation of the present invention: a balloon-type interatrial septum expansion ring, the atrial septal expansion ring is composed of an inflatable expansion ring 1 and a connecting tube 2, and an expansion hole 3 is arranged in the middle of the inflatable expansion ring 1, and the inflatable expansion ring 1 1 is provided with an air outlet 6, the connecting pipe 2 is composed of an external through pipe 4 and an internal through pipe 5, the external through pipe 4 is connected with the airbag of the inflatable expansion ring 1, the internal through pipe 5 and the inner through pipe 5 The air outlets 6 are connected, and an air-filling tube 7 is arranged on the external through-pipe 4 and the internal through-pipe 5 .
所述充气管7上设置有充气管口堵头8。The inflation tube 7 is provided with a plug 8 at the mouth of the inflation tube.
本发明工作时，可以将气囊式心脏房间隔扩张圈放入在心脏的房间隔处，然后对充气扩张圈1进行充气，这样通过逐步扩张的充气扩张圈1以及扩张孔3将心脏房间隔扩张开来，方便进行手术，与此同时，在内部通管5内通入二氧化碳气体，二氧化碳气体直接通过出气孔6进入到体内，将其他有害气体冲出体外。When the present invention works, the balloon-type heart interatrial septal expansion ring can be placed in the interatrial septum of the heart, and then the inflatable expansion ring 1 is inflated, so that the cardiac atrial septum can be expanded through the gradually expanded inflatable expansion ring 1 and the expansion hole 3 Open, convenient to carry out operation, at the same time, pass into carbon dioxide gas in the interior through pipe 5, carbon dioxide gas directly enters into the body through the air outlet 6, and other harmful gases are flushed out of the body.
