本发明为提供一种可通过活体之自然开口而将2个观察构件配置于腹腔中以确保2个视点之医疗行为及系统,而使经自然开口的医疗行为包含下述步骤,即:使用业已从息者之自然开口插入至管腔器官内之设备,于管腔器官上形成开口;使第1观察设备从已形成于该管腔器官之前述开口导入至腹腔;使第2观察设备从已形成于该管腔器官之前述开口导入至腹腔;将该第2观察设备配置于与该第1观察设备不同之位置;使该第1观察设备所取得之影像与该第2观察设备所取得之影像作选择性显示,或作同时显示;及,一面确认影像,一面于腹腔内进行所需之技术。

A medical procedure and a system are provided so that two visions are obtainable through natural orifices by means of two observational apparatuses, or one the two visions is selectable. The natural-orifice medical procedure comprises: forming an orifice in a hollow organ by using a device inserted into the hollow organ from a natural orifice of a patient; introducing a first observation device from said orifice formed in said hollow organ into an abdominal cavity; introducing a second observation device from said orifice formed in said hollow organ into the abdominal cavity; arranging said second observation device in a position different from that of said first observation device; simultaneously or selectively displaying an image obtained from said first observation device and an image obtained from said second observation device; and performing a desired procedure in the abdominal cavity while confirming the images.
