Use of a force measuring instrument during cervical dilatation.

An instrument has been designed and manufactured to measure the forces encountered during surgical dilatation of the uterine cervix. The cervical resistance of 240 patients has been measured. Initial results show lower resistance in pregnant patients compared to non-pregnant and in multiparas compared to nulliparas.
