The utility model relates to a conveying device of a sealing device for atrial septal defect under the guidance of simple ultrasound, which comprises a sheath tube and a sheath core. The sheath tube and the sheath core are hollow structures. The sheath core is pierced in the sheath tube. The inner hole of the sheath core is used for piercing the guide wire. The sheath tube includes the tube wall, the conveying channel and the handle. The inner hole of the sheath tube is a conveying channel, and the tube wall includes the end, the marking section The bending section and the hard tube body are connected with the handle, the end is a soft end, the marking section of the tube wall is wrapped with metal sheets, and the front end of the elastic bending section is provided with a traction wire capable of sliding along the tube wall. The utility model provides a soft end for preventing the scratching of the sad cavity wall at the front end of the sheath tube, a marking metal sheet is arranged on the sheath wall connected with the soft end, and a sheath tube body is arranged on the sheath tube body. It is easy to show the position and direction of the sheath head accurately by marking metal sheets in the echocardiographic environment, so as to avoid breaking through or scratching the wall of the atrium.

单纯超声引导下房间隔缺损用封堵器的输送装置
本技术属于医疗辅助器械
,具体涉及一种单纯超声引导下房间隔缺损用封堵器的输送装置。
技术介绍
房间隔缺损是左右心房之间的间隔发育不全,遗留缺损造成血流可相通的先天性畸形,目前,针对房间隔缺损人体的治疗主要采用房间隔缺损封堵术进行治疗。目前,房间隔缺损封堵术主要是在放射线下经皮封堵术,该手术是临床上常用技术,该手术无需开胸、可避免体外循环,具有创伤小、恢复快、疗效确切的优点,但是,该手术必须依赖大型影像设备,而大型影响设备产生的放射线,会对患者及医护人员产生了较大的伤害。随着医学技术的发展,目前,医护人员研发出单纯超声引导下房间隔缺损经皮封堵术,该手术是最近出现的新技术,已在国内少数大型心脏中心开展,是未来房间隔缺损封堵术的发展方向,该技术避免外科创伤的同时,又避免了大型影像设备的应用和放射线对医护人员及患者带来的人体伤害。目前,单纯超声引导下房间隔缺损经皮封堵术具体操作步骤是:穿刺股静脉置入股静脉鞘管,用右心导管在导丝配合下,将右心导管及其内的导丝从股静脉通过下腔静脉进入右心房,然后稍稍后退导丝,调节右心导管前端的 ...
