Description

微创手术用腹腔镜 技术领域
本 发明 涉及一种微创领域使用的腹腔手术的 40-80 度腹腔镜，属医疗器械技术领域。
背景技术
腹腔镜是一种带有微型摄像头的医疗器械。可以不用开腹进行腹腔内手术，以其微创特点在临床上广泛应用。腹腔镜手术就是利用腹腔镜及其相关器械进行的手术：医生将腹壁切开小口，放入穿刺器，再放入腹腔镜，腹腔镜使用 冷光源 提供照明，运用数字摄像技术使腹腔镜镜头拍摄到的图像通过光导纤维传导至后级信号处理系统，并且实时显示在专用监视器上。然后医生通过监视器屏幕上所显示患者器官不同角度的图像，对病人的病情进行分析判断，并且运用特殊的腹腔镜器械进行手术。腹腔镜是专用于人体微创腹腔手术，一般包括冷光源、视配器、摄像头、气腹机、高频电刀、光导纤维（光源线）与气腹管、显示器、二氧化碳瓶及其连接管等。其在手术中应用于腹腔内视野，形成视屏操作，使手术器械在镜头观察下完成。
目前腹腔镜均为0度、25度、30度角，虽然对腹腔手术具有一定的手术效果，但当在特殊部位的病灶条件下，不能达到角度视野的效果。
如图1所示为现有技术中的约25-30度的腹腔镜，可以看到按观察方向，斜视式，其视向角(即窥镜前端部斜面与镜管横截面的夹角)为 25-30 度夹角。如图2所示为目前25-30度的腹腔镜在手术中操作的示意图。从图中看出，在手术中，此类腹腔镜的观察角度不佳，器械与镜头互相妨碍、碰撞，甚至影响操作，尤其是当病灶位于与内外镜管的垂直面大于30度角病变处时，操作会互相影响。此外，当手术器械不能出现弯度钳时，观察和操作成为矛盾。由于手术操作必须在观察下操作，期待寻求能够更好地支持腹腔镜手术，解决上述技术问题的新型腹腔镜。
