The hysteroscope is a thin rod inserted into the uterus through the vagina and the cervical canal. The hysteroscope has a lens or a saline solution to inflate a source of light needed to illuminate the uterus, a lens or video camera to transmit the image, and the uterine uterus without touching the walls of the uterus.
Small devices such as scalpels, lasers and scissors can also be inserted into the hysterectomy to perform surgery. Hysteroscopy is usually performed as an outpatient procedure as a diagnostic procedure. General or local anesthetics and painkillers may be given to relieve the discomfort.
