The present invention relates to a hysteroscope of the type comprising an outer envelope forming a cannula, means for insufflation of a fluid, particularly a gaseous fluid, such as for example carbon dioxide, inside the uterine cavity to distend the walls thereof, and an inner envelope forming an endoscope tube, of smaller diameter than the outer envelope and adapted to slide therein, this inner envelope containing light transmission means for conducting light to the distal end of said inner envelope and comprising on the one hand means for mechanically placing the hysteroscope in operating position, substantially fluid-tight at the level of the cervix of the uterus and on the other hand a portable device for supplying said fluid, fast with said hysteroscope.

A self-contained portable hysteroscope comprising, in combination: a pair of elongated hollow relatively axially slidable elements to be inserted into the uterine cavity comprising a cannula defining an outer envelope, and an endoscope tube of smaller diameter than the cannula and axially slidably received therein; handle means attached to at least one of said pair of elements to be grasped by one hand for manipulating said hysteroscope; means attached to at least one of said pair of elements to support a self-contained source of gas and a self-contained source of light; said endoscope tube including optical viewing means for conducting light from said light source to the distal end of the endoscope tube and to return an image of the area illuminated to the proximal end of the tube; conduit means for conducting gas from said source to the distal end of said endoscope tube for detending the walls of the uterine cavity; said outer envelope being provided with means at the distal end for establishing and automatically maintaining a fluid-tight seal with the entrance to the cervix of the uterus when manipulated by said handle by one hand.
