摘要： A recyclable and adjustable interventional stent for intravascular constriction. The stent main body is divided into three parts and shaped like a waist drum with expansion parts (1, 4) being arranged on the upper and lower parts of the stent main body respectively for supporting and positioning. A variable aperture part (2) is arranged in the middle of the stent main body. The upper expansion part (1) is or is not provided with a coating; the middle variable aperture part (2) and the upper half part of the lower expansion part (4) are covered with a pericardium (3) subjected to anti-calcification treatment; and a metal wire ring (5) is passed through the lowermost edge of the stent. A compound conveying guide pipe is composed of an outer sheath (6) and a core (7). The core (7) is a hollow pipe and a wire hanging groove is arranged on the outer side wall of the tip of the pipe to hang the metal wire ring (5) of the lowermost edge of the stent. A fixing bolt (8) on the outer sheath (6) is used for fixing the relative position between the outer sheath (6) and the core (7). The stent is used to replace conventional pulmonary artery banding as, adhesion not being formed around the heart and major vessels and pulmonary stenosis not being formed, difficulties during radical surgery are not increased.

摘要翻译： 可回收和可调节的介入支架用于血管内收缩。 支架主体分为三部分，并形成为一个腰部鼓，其中扩张部分（1,4）分别设置在支架主体的上部和下部，用于支撑和定位。 可变开口部分（2）布置在支架主体的中间。 上部膨胀部分（1）是或不具有涂层; 中间可变孔径部分（2）和下部扩张部分（4）的上半部分被用于进行抗钙化处理的心包膜（3）覆盖; 并且金属线环（5）穿过支架的最下边缘。 复合输送导管由外护套（6）和芯（7）组成。 芯部（7）是中空管，并且在管的顶端的外侧壁上布置有线悬挂槽，以悬挂支架最下边缘的金属丝环（5）。 外护套（6）上的固定螺栓（8）用于固定外护套（6）和芯体（7）之间的相对位置。 支架用于代替常规的肺动脉带，因为未形成心脏和主要血管周围的附着物以及未形成的肺动脉狭窄，根本手术期间的困难不增加。
