The Surprising Medical Origins of Chainsaws

What were chainsaws originally invented for? Most know chainsaws for woodcutting, yet their startling beginnings tell a different story. These power tools, today synonymous with lumberjacking, had original purposes unrelated to forestry. Their invention was driven by a medical necessity – easing childbirth complications.

Early Medical Instruments for Childbirth

Before the modern chainsaw’s birth, its ancestor played a crucial role in medicine. In the 18th century, difficulties in childbirth prompted the creation of tools to assist delivery. Early chainsaw models were hand-cranked implements. They were designed to cut through bone and cartilage. This made it easier to remedy difficult births that endangered mothers and children. The devices aimed to speed up symphysiotomies, widening the space for the baby to be born.

In these earlier times, childbirth interventions varied in brutality and risk. But the rudimentary chainsaw model offered a more targeted approach. Despite its benefit, the practice of using such medical chainsaws faded. This was due to emerging C-sections’ increasing success and safety.

Aitken and Jeffray’s Role in the Invention

Enter Scottish doctors John Aitken and James Jeffray. They paved the way for the chainsaw’s medicinal usage with a remarkable invention. In the late 18th century, they designed a prototype to aid in childbirth, known as a ‘flexible saw’. Their version featured a chain with small teeth – quite different from the roaring engines of today’s timber industry.

The original chainsaw was a manual tool. It was much smaller, more precise, and hand-operated. Aitken and Jeffray’s design focused on minimizing the risks associated with difficult deliveries. This early version did not see widespread use. Yet, it was a significant step that inspired the evolution of the tool beyond its medical roots.
