Abstract:
A hysteroscope for carrying out endoscopic operations in the uterus by way of an elastically laterally deflectable auxiliary instrument having a distal end, said hysteroscope comprisingan inner shank and an outer shank surrounding the inner shank and forming a longitudinal channel between said inner shank and said outer shank, a first fitting for supplying rinsing fluid to be led through the inner shank into the uterus, a second fitting for removing rinsing fluid from the uterus via the longitudinal channel, a third fitting at which the auxiliary instrument is introducible into the hysteroscope and is further axially movable through a working channel, a first ramp on which the distal end of the auxiliary instrument moved axially through the hysteroscope is laterally deflectable, in order with an axial movement of the auxiliary instrument against said first ramp to deflect said distal end laterally in a direction into a first position, a second ramp which is not movable with respect to said inner shank, said second ramp being situated axially beyond said first ramp, and a deflection element with which the distal end of the auxiliary instrument is further laterally deflectable in said direction away from the first ramp and into a second position beyond the first position, wherein the deflection element is a pivotably mounted lever which is pivotable about a pivot bearing out of a rest position in response to axial displacement of said lever against said second ramp so that the lever bears against the auxiliary instrument in order to deflect the distal end further in said direction into the second position.
