Video hysteroscope

摘要

A video hysteroscope has an elongated flexible insertion tube containing a video imager head at its distal end, with a channel for a surgical laser fiber and a saline channel which emits a continuous stream of saline solution distally from the head. The articulation section is kept as short as possible, and is limited to a maximum deflection of about 30 degrees to match the geometry of the uterus.
