In the pessary with open cup simple pressure against the anterior vaginalpouch with the top of the cup, the direction of the force being directedfrom the hinges slightly backward, will cause the hinges to revolve andthe movable bar to approach the floor of the cup. The only advantageof this open variety is the non-compression of the cervix in the Fig. 241.—Thomas hinge anteversion pessary in position. The removal is easily accomplished by hooking the finger into the mova-ble arch and gently drawing on it, when the hinges will revolve and thepessary become extended as it is withdrawn. An instrument constructed on a similar principle is that shown in , 241, and 242.
