ABSTRACT:
The invention consists of an axis-traction handle with a pull-sensing grip (4) for the obstetrical forceps, whose object is to reduce the risk of injury to the fetus, caused by excessive traction force during a forceps delivery. The grip contains electronic hardware which include a strain gauge to measure the pull exerted on the axis-traction handle, and thus on the fetal head, during a forceps delivery, a sounder to alert the doctor when the pull exceeds preset safety limits, and a transceiver for the wireless transmission of the pull data to a receiver connected to a lap-top computer with specific software, which generates a graphic representation of such data.
