Straight to the point – Why Were Chainsaws Invented?
The first chainsaw was invented in the late 18th century, and was used exclusively in the medical field for assisting with complications during childbirth.
Chainsaw History & Timeline [Infographic]
Who Invented the Chainsaw?
Studies attribute the invention of the chainsaw to Scottish Surgeon’s John Aitken and James Jeffray who pioneered the invention in 1830. Back then the chainsaw was used exclusively in the medical field.
The tool was used to widen the pelvis during childbirth to help the baby pass. Due to the Aitken/Jeffray chainsaw’s unwieldy and cumbersome nature, individuals couldn’t use it in another context.
A German orthopaedist (Bernhard Heine) further developed the chainsaw soon after. While the original chainsaw helped women with complications in giving birth, Bernhard’s chainsaw was effective in surgeries and dental implants for cutting bones.
This one was smaller and had a more practical design enhancing its effectiveness. Aitken, Jeffray and Heine were the ancient pioneers of the invention and development of chainsaws. The invention later paved the way for the development of the mighty modern-day chainsaw.
What Were the First Chainsaws Like?
The first chainsaws were very different from the ones we see or use today. They were cumbersome due to the materials and designs the inventors used in making them. However, the chainsaws that were used for medical procedures were effective… if a little gruesome!
As time went by, other industries started taking in interest in the idea and some started designing chainsaws specifically to help fell trees and cut timber. They thought if you could really power this thing, it could cut through anything!
In the early 20th century the newly-introduced gasoline engine was used as a means to rotate the chain at very high speeds therefore changing the woodcutting industry forever.
Why Were Chainsaws Invented?
While professionals in various industries enjoy the effectiveness of chainsaws, the first chainsaw was designed for a different purpose. Aitken (a Scottish surgeon) invented the first chainsaw in the 18th century to assist with problematic child birth.
The doctors could use this hand-cranked chainsaw to cut through the mother’s ligaments and cartilage in order to widen the pelvis – a process referred to as symphysiotomy.
With the pelvis widened, it was easier to deliver the baby. While it seems cruel, doctors used it to save the lives of the mother and newborn.

What Was the Role of Chainsaws in Symphysiotomy Treatment?
Symphysiotomy treatment is a medical procedure that involves widening the pelvis during birth to allow the baby to come out.
Doctors used chainsaws in the early days to divide the public symphysis cartilages to allow effective childbirth. With the emergence of caesarean procedures, this process and term have become outdated.
While the medical procedure helped to streamline childbirth, many ladies referred to it as butchering. Symphysiotomy had various adverse effects on the ladies who underwent it. For instance, the procedure left most ladies unable to sit and walk after delivery, while others reported long-term effects due to the process.
What Did the Medical Chainsaw Look Like?
Early chainsaws resembled a kitchen knife, but with a chain of small metal teeth that could be rotated by a handle. The availability of this tool saved critical seconds when complications arose during child birth.
Despite the simple outer surface, the internal construction was complicated to suit its medical role. Despite the great impact on child delivery, the very first incarnation of the chainsaw didn’t last long.
In 1830, a Germany Orthopaedist, Bernhard Heine, improved the design and named it the osteotome – a name derived from Greek for osteo (bone) and tome (cut).
This equipment had features that made it vital for cutting bones during surgeries and dental implantation. The Orthopaedist invented the equipment with small teeth around the chain.
When Did the Use of Chainsaws For Childbirth Stop?
With the success of chainsaws in helping ladies give birth, doctors continued to use the equipment up to the early 1900s. Nevertheless, the manufacturers included some features to improve its safety and functionality.
However, the emergence of caesarean has entirely negated the use of chainsaws during childbirth. Medical experts have rejected the use of these saws for safer alternatives. The use of this equipment to help ladies give birth was very painful!
How Have Chainsaws Evolved Over Time?
