Description

中心式电子宫腔镜、镜头安装端盖及宫腔移动手术平台 技术领域

宫腔镜是一种新的、微创性妇科诊疗技术，用于子宫腔内检查和治疗的一种光源内窥镜，它能够利用镜体的前部进入宫腔，对所观察的部位具有放大效应，凭借直观、准确的优势，成为妇科出血性疾病和宫内病变的首选检查器械。
近年来，随着技术的不断发展，一次性电子宫腔镜发展迅速，相比于非一次性电子宫腔镜，一次性电子宫腔镜具有干净卫生、不需要多次消毒，镜头成像质量有保证等优势，近年来被广泛使用。
在使用宫腔镜进行检查的过程中，宫腔镜具有镜体的端部需要进入患者的体内，以获取患者体内的图像。传统宫腔镜具有镜体的直径较大，往往会导致在进入患者体内检查的时候，不可避免地与患者的身体相接触，给患者造成不必要的伤害。另外，具有较大的镜体直径也在一定程度上限制了传统宫腔镜的活动范围，一定程度上影响了宫腔镜检查的效果。
另一方面，受限于成像质量、镜头制造技术以及制造成本等方面的限制，传统一次性电子宫腔镜的具有镜体的端部尺寸进一步缩小十分困难，成为制约一次性电子宫腔镜进一步发展的关键因素。
