Outlet forceps, e.g. Wrigley's forceps, are small forceps used for lift-out deliveries and at caesarean section.
Outlet forceps are used when:
- the fetal scalp is visible without separating the labia
- the fetal skull has reached the pelvic floor
- the sagittal suture is in the antero–posterior diameter or right or left occiput anterior or posterior position (rotation does not exceed 45°)
- the fetal head is at, or on, the perineum.
