There is disclosed herein a vacuum extractor for use in childbirth and comprising a bell shaped cup having a relatively thin outer flared edge, a hollow stem extending from the cup, and the stem including a handle. A vacuum source can be connected to the stem to draw a vacuum within the cup. A liner is hooked over the flared edge of the cup and provides a relatively large soft and resilient bead for the outer edge of the vacuum extractor which contacts maternal and fetal tissue. The liner is stretched into and secured within the cup and includes an aperture for allowing a vacuum to be drawn within the cup.
