The utility model discloses a
dilator for
cervix examination, which belongs to the technical field of dilators and comprises an upper dilating sheet and a lower dilating sheet, two connecting plates are fixed on one side of the upper dilating sheet, a grab
handle is fixedly connected with one side of the lower dilating sheet and positioned between the two connecting plates, and the connecting plates are hinged with the grab
handle. A locking
assembly is arranged between the connecting plate and the grab
handle, a lighting mechanism is arranged in the upper dilation piece and comprises an
optical fiber bundle, a mounting groove is formed in the wall of the upper dilation piece, the
optical fiber bundle is located in the mounting groove, a mounting base is fixedly connected to the top of the upper dilation piece, one end of the
optical fiber bundle extends into the mounting base, and a
light source assembly is arranged in the mounting base. The
optical fiber bundle is used for transmitting
optical energy,
energy loss in the transmission process is reduced, the
optical fiber bundle is located in the installation groove, use of the operator is prevented from being affected, and the
optical fiber bundle can be better attached to the expander. And the
light source assembly and the mounting base are detachably connected, so that cyclic utilization is facilitated, and resource waste is reduced.
