This paper first introduces the recent development of the popular hysteroscopy, the international minimally invasive diagnosis instrument, and then analyzes the lighting and video of hysteroscopy. According to high energy consumption of common hysteroscopy, front located hysteroscopy system is put forward. The no light spot principles, the lens structure, the manufacture process of lens prototype, the trial manufacturing process of power box are all discussed in this paper. It is the first time that prototype has been design and tested in domestic. In the normal conditions, the energy consumption decreased by 298/300. And the volume, the weight, and the price of the designed front located hysteroscopy are greatly reduced. Moreover, tests show that it can apply to special conditions such as the disaster relief field and field operation.
