Cranioclast
Cranioclast
Cranioclast (pronounced: /ˈkreɪ.ni.oʊ.klæst/) is a medical instrument that was historically used in obstetrics for the purpose of craniotomy, a surgical operation where a bone flap is temporarily removed from the skull to access the brain. The term is derived from the Greek words "kranion" (κρανίον), meaning "skull", and "klastos" (κλαστός), meaning "broken".
History
The cranioclast was first introduced in the 19th century as a tool for obstetrical procedures. It was primarily used in cases where the baby's head was too large to pass through the mother's pelvis during childbirth, a condition known as cephalopelvic disproportion. The cranioclast was used to crush and remove the skull, allowing for the rest of the body to be delivered. This procedure, known as craniotomy, was typically performed when the baby was already deceased.
Usage
The cranioclast consists of two branches which are introduced separately into the uterus. These branches are then assembled and locked together. The instrument is then used to grasp, crush, and extract the fetal skull. The procedure is typically performed under anesthesia.
