Cranioclast (Diaclast)

A cranioclast is a surgical instrument that is used to separate the fetal skull from its torso. This procedure is performed to allow the dead fetus to pass naturally through the mother's birth canal.

Although this procedure is considered rare, it may be necessary when a stillborn fetus cannot be delivered naturally. Separating the fetal skull from its body can reduce the size of the fetus, allowing it to pass through the mother's birth canal. Thus, this procedure may help prevent complications associated with the inability of a dead fetus to pass through the birth canal.

Cranioclast (Diaclast) is a specialized instrument that is used in surgery. It has two plates that are used to separate the fetal skull from its torso. The plates are inserted into the skull and then pulled apart to separate the skull from the torso.

Although the procedure of separating the fetal skull from its torso may seem scary, it is safe and effective when performed by experienced surgeons. The cranioclast surgical instrument (Diaclast) is an important tool in surgery that can help prevent birth complications associated with the inability of a dead fetus to pass through the mother's birth canal.

In conclusion, a cranioclast (Diaclast) is a surgical instrument that is used to separate the fetal skull from its torso. This procedure is performed in the case of a dead fetus to ensure that it can pass naturally through the mother's birth canal. Although this procedure is rarely used, it can be an effective way to prevent birth complications associated with the inability of a dead fetus to pass through the birth canal.



Cranioclast (Latin diaclaustrum, from ancient Greek διακλάω - “tear”, “cut”) is a surgical instrument for separating a child’s skull from the body during childbirth. Cranioclast is used in case of stillbirth of the fetus to ensure its natural passage through the birth canal.

A cranioclast is a metal rod with a rounded end and a hole in the center. It is inserted through the fetal abdomen and then through an opening in the skull. The rod is advanced until it reaches the base of the skull. The cranioclast is then removed and the fetal skull is separated from the body, allowing the baby to pass through the birth canal naturally.

When using cranioclast, care must be taken not to damage surrounding tissue or cause bleeding. It is also important to consider the size and shape of the fetal skull to avoid injury and damage.

Cranioclasts are rarely used nowadays because safer and more effective methods of skull removal exist. However, in some cases, such as large fetuses or other complications, cranioclast may be the only possible method of skull separation.



Cranioclasm (Diaclasm) is a surgical instrument for separating the skull of an infant (newborn) from the body. This procedure is required if the baby has died in utero, allowing the mother to pass through the birth canal gently and naturally. It can only be performed by a professional doctor or midwife.

Cranioclasma is usually performed at the time of death of a child by caesarean section, when the fetus is already dead. Difficulty in childbirth, malpresentation of the fetus, the risk of hypoxia and abnormalities of the cardiovascular system can also lead to the need to use cranioclasm. Using this tool requires special experience and knowledge, so it is not recommended for use unless necessary.

Performing the cranioclasation procedure requires an obstetrician to be highly qualified and knowledgeable about technology. Preliminary assessment of the fetus is carried out by listening to its heartbeat and visually examining the mother's abdomen to determine whether the fetus is in abnormal positions or is unable to move independently. To perform this procedure, use a special knife or scissors. The medical specialist should have experience working with cranioclases due to his training and knowledge.

After performing cranioclase, monitoring is necessary to assess the viability of the fetus. Observation and diagnostics are also necessary to determine the extent of damage.
