Abstract
For the examination of the fallopian tube, a salpingoscope has a first endoscope telescopically receiving a second endoscope which are displaceable relative one another. The optics of the second endoscope and the distal end of the outer guide shaft of the second endoscope are matched to the small diameter of the fallopian tube. An inner shaft guarantees an adequate stability of the thin optics of the second endoscope and an obturator may be used to replace the optics of the second endoscope while introducing the constricted end section of the outer shaft into the fallopian tube.

In a method for the examination of the fallopian tube in which a first endoscope is positioned with its distal end adjacent to the fallopian tubes from the outside and a second, thinner endoscope is supported in a guided fashion in the first endoscope and has its distal end introduced into the fallopian tube, the improvements comprising providing a second endoscope having a shaft surrounding the optics, said shaft having a distal end of a reduced diameter, said step of introducing the second endoscope includes inserting the distal end of a reduced diameter into the fallopian tube and then positioning the optics of the second endoscope to project from the distal end and to be freely displaced in a longitudinal direction of the shaft of the second endoscope and the fallopian tube.
In a salpingoscope for the examination of the fallopian tube, said salpingoscope including a first endoscope that has an angular ocular part and an instrument channel through which a second endoscope comprising an outer shaft is displaceable in a longitudinal direction of the first endoscope, the improvements comprising said second endoscope comprising an outer shaft which has a distal end section projecting beyond the instrument channel of the first endoscope, an inner shaft immediately surrounding an optics of the second endoscope, the distal end section of said outer shaft comprising a portion having a reduced diameter which extends up to the end thereof and the optics of the second endoscope projecting out of the end of the reduced diameter portion of the outer shaft and being displaceable in a guided fashion therein.
