摘要
The invention relates to a combination of a vaginal speculum with a single-lens colposcope for use in a screening process for detecting mucosal abnormalities of cervical intraepithelial neoplasia or invasive cancer, e.g., in the vaginal cavity or on the external parts of the genitalia, as an addition to a Pap Smear screening process. The vaginal speculum is identical to a conventional speculum in its shape, dimensions, and function and differs from a conventional instrument only by having on the inner surface of the lower blade a small projection with a slot for guiding a single-loop colposcope. The latter consists of a tubular rod that can be slidingly inserted into the aforementioned slot and support on its distal end an optical lens. The lens may have a central opening for insertion of surgical instruments, e.g., a biopsy sampler. The proximal end of the tubular rod may support a rubber bulb for suction fluids from the distal end of the lower blade via the tubular rod. In use, the colposcope is inserted into the vaginal speculum through the guide slot so that the physician can manipulate with the colposcope by moving it in axial direction for focusing the lens and by turning the rod to the left or to the right for observing an area of interest. The vaginal speculum and the colposcope can be molded from plastic and can be disposable.
