A surgical instrument used to rupture the amniotic membrane (i.e., the amnion - the thin, tough membrane that lines the chorion and contains the foetus and the amniotic fluid) to assist in childbirth, without causing injury to the mother or foetus. It is typically long and shaft-like, and terminates in a rounded nose with a sharp hook. It is typically made of high-grade stainless steel or durable plastic materials, and may be straight or curved to follow the natural contours of the birthing canal into which it is inserted. Amniotic membrane rupture may also be performed using an amniotome or forceps and/or a trocar. This is a reusable device.
