Description
技术领域
本发明属于医疗器械,具体涉及一种管道直径较细的一种柔性小肠镜。
背景技术
目前用于诊断小肠病变的方式主要分为胶囊内镜、双气囊小肠镜、单气囊小肠镜等检查技术。双气囊小肠镜主管道直径较大,小肠一般5米多长且褶皱多、弯道多,越深入气囊动力易不足造成探头走不到头,并且只能从患者口或者肛门检查,反复的钩拉动作使患者十分不适;零部件多、结构较复杂,需要专门的消毒室对其消毒,特别耗费时间和人力。
发明内容
为了解决上述问题,本发明提供了一种柔性小肠镜,其操作方便,主管体内各管道道一体成型结构紧凑,可以从鼻腔进入人体小肠,提高患者舒适度。
一种柔性小肠镜,包括主管体、主支撑气囊和嵌在主管体一端部内的硬质探,所述硬质探头内设有摄像头和光源;
所述主管体内开设有活检管道、电缆管道、进气管道,所述活检管道的出口处对应设在硬质探头上,所述摄像头和光源设置在电缆管道的出口处;所述主支撑气囊包覆在主管体外壁上靠近探头且与进气管道连通;
所述电缆管道用来容纳电缆,所述电缆的输出端连接摄像头和光源、输入端连接电路板,所述电路板由电池供电,所述电路板上设有用于将摄像头影像信息传输到显示器的USB接口。
上述柔性小肠镜,还包括头端可转向的外套管,所述外套管可拆卸的套装在主管体外,所述外套管上开设有与主管体外壁上对应的进气管道开口、活检管道开口、电缆管道开口和配合主支撑气囊涨缩的外支撑气囊;所述外套管(5)的头部为用来控制主管体(1)转向的转向头、尾部设有用于调节转向头的转向旋钮。
上述柔性小肠镜,所述主管体的直径为4.5-6mm。
上述柔性小肠镜,所述主支撑气囊长度为40-60mm。
本发明的有益效果为:活检管道3中通气、通水用来清理肠内杂物,主支撑气囊6用来撑起肠壁便于肠镜在褶皱的小肠内前行;外套管5采用现有技术实现转向功能,医务人员通过转向旋钮52控制转向头51在小肠弯曲处能快速、顺利的拐弯前行。电缆管、进气管都集成在主管体内并且采用柔性材料,外套管设置转向头,既能极大减肠镜直径又能保证探头在小肠内有力深入,很轻易的观察到小肠尽头,提高疾病诊断的准确率。同时肠镜径较小,可以从鼻腔进入,相对于从口腔或肛门检查,患者会比较舒适。本产品的支撑气囊为一次性弹性产品,因此整个主管体也为一次性的,医疗诊断更加卫生,不会发生交叉感染。
