技术领域
本发明涉及医疗器械技术领域，尤其涉及可视化医疗器械，具体是指一种用于人流术的可视化手术用组合件及相应内窥镜。
背景技术
在可视化人流临床手术中，经常需要使用可视化内窥镜，用于对早期胚胎的观察、定位与吸出。在早期的人流手术中，由于可视化的实现困难，基本是将带有通道的金属管在后端接续吸引器，在宫腔内吸出宫体的表面黏膜，来实现中止胚胎的继续受孕。由于对宫腔内无法准确的定位胚胎，一般实施宫腔内表面黏膜的全吸出手术，但这样就对非胚胎黏膜层的损伤无法控制。随着技术的不断发展，逐渐出现了B超探视下的胚胎定位，使定位吸除胚胎的可视化手术比盲视下的中止手术有所进步。再到后期，出现超细光纤，对胚胎直接定位，进行直接吸出手术。近期，使用具有传感器的光电转换器件使得可视化有了较大进步，胚胎定位更加精准。上述方式都一定程度实现了可视化人流中止术，对胚胎具有一定程度的准确定位及完全的中止成功率。
一般情况下胚胎中止术中使用的引流管可采用金属材质或者塑料。金属材质的管件可重复消毒使用。而现行广泛使用的是带摄像头的塑料制品，只可一次性使用，基本满足了在近距离观察胚胎位置后对胚胎进行吸出的手术。手术的方式是以负压的形式吸除胚胎从而达到中止继续受孕的目的。
在医学临床中，为避免可能出现的医学纠纷或有潜在的其它病理情况，需要在人流手术后能够进行术后腔体的观察，包括黏膜层的确认及深体层的确认，在术后通过使用灌流体装置与可视人流内窥镜的组合，将负压式的方式改为膨宫式的工作原理，由单纯的手术改为术后观察确认手术的结果，能够最大限度使患者免受不需要的过度的手术，或者发现其它的病理情况告知患者、建议治疗方案等、从而避免医疗纠纷的产生。
由于现有的可视人流内窥镜仅能满足在观察胚胎定位后使用引流管对胚胎吸除，因此此 类产品对可视图像的传感器的高分辨、及光照的距离没有特殊的要求。然而，随着医护人员对术后的腔体内貌观察的需要，因此在实施中止术后，能够进行灌注液体促使宫腔膨起扩大留出空间可观察腔体内况，就需要具备高亮度、高分辨率的新型可视人流内窥镜产品、满足医护人员临床上的新需求，所以本产品的技术发明内容是符完全满足临床上新应用的。
