ABSTRACT:
An improved instrument for microscopic examination through the throat of the womb including a guide-tube and a microscope. The guide-tube is adjustably attached to a vaginal speculum and has its own illumination system, a graduated collar for focusing the microscope, and fine-adjustment clamps for preventing the accidental movements of the microscope. The microscope is adjustably positioned in the guide-tube so that it can focus on a plurality of microscopic fields without movement of the guide-tube. It has two illumination systems, one providing light for vision, the other an electronic flash for a photographic camera. The microscope can be removed from the stationary guide-tube, its objectives and oculars replaced by elements with different powers, and reinserted in the guide-tube to provide examination at variable magnifications.
