Chainsaws were originally designed to assist in surgeries, specifically to simplify the childbirth process. Before modern advancements, cesarean sections and surgical procedures were rare and complex. The invention of the chainsaw revolutionized childbirth, making cesareans more accessible and manageable for both doctors and mothers.
While chainsaws are widely used today for cutting wood and crafting by carpenters, their primary purpose was medical. Scottish doctors James Jeffrey and John Aitken created the first chainsaw, a much smaller tool than the ones we see today, to aid in obstructed labor. This life-saving innovation helped mitigate risks to both mother and baby during complicated deliveries, particularly when cesarean sections were required. Its introduction marked a pivotal moment in surgical history, offering safer outcomes in high-risk childbirth scenarios.
Function of Chainsaws Invented
Some babies become stuck in the birth canal, making timely delivery challenging and increasing the risk of infection for both mother and baby. Today, modern technology has significantly improved the childbirth process, with tools like chainsaws playing a critical role in facilitating cesarean sections. This innovation highlights the primary reason chainsaws were invented—to aid in complicated childbirth surgeries.
Historically, in 1777, Dr. Sigault performed a groundbreaking procedure by cutting the pubic joint of a 40-year-old woman named Souchot, whose previous four babies had died during childbirth. Medical staff believed vaginal delivery was impossible, and a c-section was the only option, despite its risks. Remarkably, the surgery succeeded, saving both mother and child. This milestone underscores why chainsaws were initially created: to assist in life-saving c-sections and improve surgical outcomes for women during childbirth.

Improvement in Symphysiotomy
Two Scottish doctors, James Jeffrey and John Aitken, revolutionized the symphysiotomy method by developing the Aitken flexible chainsaw. Their innovation streamlined childbirth procedures by reducing the time needed to remove a woman’s pelvic bone, significantly improving safety. This chainsaw featured a fine serrated chain with removable teardrop-shaped handles, allowing doctors to attach a blunt-ended needle for precision.
Before this invention, sharp knives and rigid saws were used, which prolonged surgeries and increased the risk of infection, often leading to fatal outcomes for mothers. The chainsaw’s efficiency minimized these risks, ensuring safer deliveries for both mother and child.
In 1890, Italian obstetrician Leonardo Gigli refined the Aitken chainsaw into the Gigli twisted wire saw, adding T-shaped handles for easier grip. This tool featured a sharp wire chain that could be precisely positioned. Though modern surgical tools and advancements in anesthesia have enhanced cesarean sections, flexible and Gigli chainsaws remain vital in certain procedures. These innovations highlight the original purpose of chainsaws: to save lives during complex childbirth surgeries.
The Invention of The Electric Chainsaw
In 1897, inventor and naturalist John Muir created the first electric chainsaw. However, the massive device, weighing hundreds of pounds and requiring a crane for operation, was impractical and ultimately failed. In 1905, San Francisco introduced the endless chainsaw, a tool so large it required multiple operators. A decade later, Canadian James Shand developed the first portable chainsaw, which, though still bulky, marked significant progress.
In 1926, German mechanic Andreas Stihl revolutionized logging by inventing the first electric chainsaw, followed by a gas-powered version in 1929. Both, however, required two operators. It wasn’t until the 1950s, following advancements in materials like aluminum, that lightweight, one-person chainsaws became feasible.
Modern chainsaws and other surgical tools have transformed medical procedures, making them safer and more efficient. Advanced technologies now support not just cesarean sections but a wide range of surgeries, reducing risks and improving outcomes. Surgeons can operate with precision, significantly lowering the chances of complications or failure.
This history underscores the critical role chainsaws played in advancing both medical and industrial applications, proving their invention was a necessity.
