Hysteroscopes
First Claim
1. In a hysteroscope having an entrance adaptor being sealably attached to an entrance of a uterus by a negative pressure and having a passage to slidable receive a shaft having an optical system, said shaft being movable through the passage for insertion into the uterus through the cervical passage, the improvements comprising a guiding element having a distal end provided with means for securing the element to the adaptor and a proximal end having means for mounting the shaft with the shaft extending through the element and into the adaptor, said guide element comprising at least a first tube telescopical receiving a second tube, said tubes being movable from an elongated idle position with a majority of the second tube extending out of the first tube to a contracted position with a majority of the second tube being telescopically received in the first tube, handle means for moving the tubes to the contracted position, and spring means for biasing the tubes toward the idle position, the length of the guide element for the idle position being selected so that the distal end of the shaft is positioned adjacent an opening of the passage of the adaptor.
