[Improved Bamberg divergence forceps. Modification for the prevention of soft tissue injuries of the pelvis].

Constant and limited (max. 300 g) force of application by the Bamberg divergent forceps helps to prevent compression injuries and slippage of the forceps with resultant trauma. No serious foetal lesions have been observed over a period of 9 years. Maternal soft-tissue injuries were somewhat above the range of vacuum extractions. This prompted us to consider modifying the Bamberg forceps with a view towards preventing such maternal injuries.
