The chainsaw, a ubiquitous tool today in the timber industry, evokes images of lumberjacks felling giant trees. However, the original purpose of this powerful instrument is far removed from forestry. Surprisingly, the chainsaw was not invented to cut wood, but rather to assist in childbirth.
For centuries, childbirth was fraught with danger, and difficult deliveries often posed life-threatening situations for both mother and child. While advancements like pain relief medications and improved sanitation drastically increased maternal safety over time, surgical interventions were sometimes necessary. Among these procedures were Cesarean sections (C-sections) and symphysiotomies. C-sections, while recorded as early as the 1500s, were incredibly risky and typically a last resort. A more common, yet still perilous procedure was the symphysiotomy. This involved surgically dividing the pubic symphysis, a joint in the pelvis, to widen the pelvic opening and facilitate childbirth.

Before the invention of the chainsaw, symphysiotomies were performed using hand tools, demanding both speed and precision from the surgeon. This was a challenging task, and the procedure carried significant risks. It was against this backdrop of medical necessity that the chainsaw was conceived.
In the late 18th century, two Scottish doctors, John Aitken and James Jeffray, innovated a device that would revolutionize symphysiotomies and other bone-cutting procedures. These weren’t engineers or toolmakers, but rather medical professionals seeking a more efficient and effective way to perform delicate surgeries. Their invention, developed between 1780 and 1785, was a prototype of the chainsaw we recognize today, albeit designed for a vastly different purpose.
The design of this medical chainsaw was ingenious for its time. It was modeled after a watch chain, featuring small teeth that moved along a chain when operated by a hand crank. Imagine a surgeon, not wielding a roaring engine, but carefully cranking a handle to drive a toothed chain. This hand-cranked chainsaw was intended to make the process of cutting through bone, specifically the pubic symphysis, faster and more controlled than using traditional knives and chisels. It was also applied to the excision of diseased bone, demonstrating its versatility in surgical applications.
Obstetricians and gynecologists of the era quickly recognized the advantages of this new tool. The medical chainsaw offered a significant improvement over previous methods for performing symphysiotomies. It allowed for a cleaner and potentially quicker cut, which was crucial in time-sensitive and high-risk procedures. This early adoption highlights the immediate impact and perceived benefit of the chainsaw within the medical community.
However, the medical chainsaw’s reign in operating rooms was relatively short-lived. While it was later mechanized in the 19th century to enhance its ease of use, a new surgical instrument soon emerged that proved even more effective for bone cutting. This was the Gigli twisted wire saw, which became the preferred tool for procedures that required cutting bone.
By 1905, the mechanized chainsaw, having been superseded in the medical field, found a new and lasting application in the timber industry. Its bone-cutting capabilities translated effectively to wood, and the mechanized chainsaw was adopted for felling trees. Thus, the instrument originally designed to ease the pain and danger of childbirth transitioned into the powerful logging tool we know today.
In conclusion, the answer to “Why Was The Chainsaw Invented?” is surprisingly rooted in 18th-century medical needs, specifically the challenges of childbirth and the necessity for efficient surgical procedures like symphysiotomies. From its origins as a hand-cranked surgical instrument designed by Scottish doctors, the chainsaw embarked on an unexpected journey, ultimately finding its iconic place in the world of forestry and timber. The next time you see a chainsaw, remember its fascinating and little-known history as a tool first intended to bring life into the world, rather than cut down trees.
