The modern-day chainsaws we’re used to seeing are mainly utilised for tree cutting. Shockingly, the chainsaw was originally invented to assist in childbirth – yes, you read that correctly. The doctors’ chainsaw was used during symphysiotomies.
The original chainsaw was invented and used by two Scottish doctors in the 1780s. Interestingly, it’s also the first Stihl chainsaw because the first wood chainsaw was invented by Andreas Stihl – the founder of the Stihl chainsaw company. Stihl also claims to have invented the first chainsaw for use by one person in 1950 – check out all the Stihl chainsaw years made for more info.
The original chainsaw looked more like a modern-day kitchen knife than what we would call a chainsaw nowadays. In the 1780s, in a bid to make the removal of the pelvic bone easier and less time-consuming two doctors named John Aitken and James Jeffray invented the chainsaw. In 1883, a patent for a chainsaw for cutting boards was passed and then subsequently more and more chainsaws developed.
The original chainsaw was used in a symphysiotomy, the preferred method for quickly removing a child from a woman’s womb for almost three centuries. Before it became the horror-movie murder weapon of choice or the preferred method of chopping down trees, the chainsaw was actually intended to be used in medicine. From there, other inventors and logging tycoons tweaked and remodeled the chainsaw into what we have today – which, thankfully, is no longer used on humans.
how was a chainsaw used in childbirth Related Question:
Did they use chainsaws in childbirth?
The doctors’ chainsaw was used during symphysiotomies. This was a procedure carried out on pregnant women during birth, in place of a caesarian section which is now the modern practice.
When did chainsaws stop being used for childbirth?
In light of this success, the chainsaw was eventually mechanized in the later 19th century to increase its ease of use by OB/GYNs on expectant mothers. However, shortly after this, the chainsaw was superseded by the Gigli twisted wire saw, which was most commonly used to cut bone.
What is Symphysiotomy operation?
Symphysiotomy is an operation that is done to increase the size of the pelvic outlet to permit vaginal delivery of a baby. The procedure involves surgically dividing, under local anaesthesia, the cartilage of the symphysis pubis.
Why was the chainsaw invented meme?
It is dark. A meme is going viral of people reacting to when they find out why chainsaws really were invented and a video on TikTok has claimed chainsaws were originally invented to help with childbirth. So if you’ve found yourself here because you want to know the answer, you’re about to find out.
When was the gas powered chainsaw invented?
In 1929, Stihl patented the first gasoline-powered chainsaw called the tree-felling machine. These were the first successful patents for hand-held mobile chainsaws designed for woodcutting. Andreas Stihl is most frequently credited as being the inventor of the mobile and motorized chainsaw.
When was the saw invented?
Around 5000 B.C. Germanic tribes invented the first saw. They nicked small teeth into half moon shaped flints.
What’s the best angle to sharpen a chainsaw chain?
Always file at right angles to the guide rail. The right sharpening angle depends on the saw chain and the wood that you want to cut. The sharpening angle will generally be between 25° and 35° – the harder the wood, the greater the angle.
Is Symphysiotomy still performed?
Currently the procedure is rarely performed in developed countries, but is still performed in “rural areas and resource-poor settings of developing countries” where caesarean sections are not available, or where obstetricians may not be available to deliver subsequent pregnancies.
Can you cut the pubic bone?
The procedure involves slicing through the cartilage and ligaments of a pelvic joint (or in extreme cases, called pubiotomy, sawing through the bone of the pelvis itself) to widen it and allow a baby to be delivered unobstructed.
Does a woman’s pelvis break during childbirth?
The left and right bones of your pelvic girdle are joined at the front by a narrow section of cartilage and ligament. This is called the pubic symphysis, or symphysis pubis. As the pelvic bones loosen during pregnancy, the pubic symphysis can temporarily separate. This is not a dangerous condition.
When were chainsaws first used to cut wood?
The origin of chain saws in surgery is debated. A “flexible saw”, consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (c. 1783–1785) by two Scottish doctors, John Aitken and James Jeffray, for symphysiotomy and excision of diseased bone, respectively.
What year did Stihl start making chainsaws?
Andreas Stihl designed and hand built his first chainsaw in 1926. The saw was electrically powered, and weighed about 48 kg (106 lb).
What chainsaw do loggers use?
Stihl is the most popular chainsaw for professional loggers. It has a long-lasting chain, and you can also enjoy the exceptional cutting speeds available with this brand of chainsaw. Additionally, the chains are high-performance, low vibration, and quiet in their performance.
Who discovered the saw?
According to Chinese legend, Lu Ban – a structural engineer, carpenter and inventor during the Zhou Dynasty, is credited with discovering the saw. After cutting his hand on a leaf with a spiny texture, he was inspired to replicate the serrated edge to create a tool.
Why do saws have teeth?
The small amount of teeth means the blade bites more rooted into the wood, which results in a faster cut. The faster the speed of the cut means a rougher cut.
