A cervical clamp for preventing reflux of a fluid medium such as carbon dioxide or a saline solution injected into a uterus. The clamp has a plurality of outwardly bowed, flexible fingers for gripping a cervix. The fingers operate between an open finger position for receiving the cervix and a closed finger position for grasping the cervix and radially compressing it against a sheath in the cervical canal through which the fluid medium is injected into the uterus.
