Winter Cranioclast 36cm

Clinical Application

Designed for use in obstetric destructive procedures, this Winter cranioclast enables controlled collapse and extraction of the fetal cranial vault in cases of obstructed labor where fetal demise has occurred or maternal life is threatened and alternative measures are not possible. The instrument provides firm purchase on the skull to allow progressive compression and delivery in confined pelvic conditions. Use is limited to experienced obstetricians and must follow institutional clinical and ethical guidelines.

Design & Configuration

The long 36 cm shank provides necessary reach into the birth canal while preserving hand clearance for the operator. Scissor-style handles transmit mechanical advantage to stout, opposing jaws that are shaped to engage and collapse the cranial bones. This geometry concentrates compressive force at the jaws for effective, controlled crushing while the extended shaft allows the clinician to operate at a safer distance from the maternal perineum. The overall configuration emphasizes predictable force delivery and tactile feedback during closure.
