The chainsaws once used for childbirth

And yes, as bizarre because it sounds, the chainsaw wasn’t invented to chop wood. Originally, it had been invented within the 16th century to assist doctors give birth to pregnant women. The latter were trying to save lots of the babies of patients affected by complications during childbirth. At that point, the risks of death for pregnant women and infants were very high. cesarean delivery didn’t exist in the least, thanks to the high risk of infection. Doctors therefore had to resort to rather barbaric medical techniques.

In 1597, the symphysiotomy was popularized for childbirth. Consistent with the definition of the CNRTL, National Center for Textual and Lexical Resources, it’s “the section of the pubic symphysis allowing the pelvis to be enlarged so as to facilitate childbirth”. Consistent with the definition of the term within the “Larousse”, “the symphysiotomy gives advantageous results when the transverse diameters of the pelvic excavation or the lower strait are narrowed”.

Are chainsaws a medical tool?

A rather painful thanks to enlarge the pelvic diameter of girls to permit passage of B Ebe. This practice is going to be used for nearly 300 years, employing a simple knife. together can imagine, it took time and was extremely painful for the pregnant woman. However, this surgical practice was considered one among the safest within the 18th century.

In the 1780s, two Scottish physicians, John Aitken and James Jeffray, created a replacement tool to enhance this practice. They develop a mechanical chain made from toothed teeth which is operated manually with an ivory handle at each end. Inserted into the woman’s pelvis, this gynecological chainsaw wrapped round the pubis and therefore the doctor moved back and forth to chop it. The tool allowed a more precise and in particular more regular cut.

Chainsaws that have evolved over time

In 1830, the German doctor and orthopedist Bernhard Heine decided to enhance this medical device. He invents a bone saw, called an osteotome. The chain is then activated by a crank and wraps around a guide blade. This made it possible to show endlessly. This modernization allowed the practitioner to position the tool precisely and cut the pubis cleanly and quickly .

On the strength of its success and efficiency, its prototype is developing massively within the medical profession and it also wants to perform other surgical operations and dissections. whilst anesthesia begins to become popular, the utilization of the osteotome continues to be recurrent thanks to its proven effectiveness.

At the end of the 19th century, symphysiotomy gradually gave thanks to cesarean delivery under general anaesthesia. A replacement surgical practice which ends up in fewer complications within the future, unlike symphysiotomy. A change that comes as hygiene conditions improve in hospitals.
