A blinded histologic review suggested that obsidian wounds contained fewer inflammatory cells and less granulation tissue at 7 days. At 42 days, all wounds were barely detectable, thus precluding scar width analysis. At 21 days, scar width was not different in the two groups. Scar width, however, was significantly less in the obsidian wounds at 7, 10, and 14 days ( p < 0.005). While the word scalpel derives from the Latin word scallpellus, the physical instruments surgeons use today started out as flint and obsidian cutting implements during the Stone Age. Tensile strength of the two wound types was not different at 7, 14, 21, and 42 days. The surgical knife, one of the earliest surgical instruments, has evolved over 10 millennia.

Each rat received two parallel 8-cm dorsal skin incisions, one with an obsidian scalpel and the other with a surgical steel scalpel (no. Skulls from the same time and place show signs of brain surgery. In order to determine if skin incisions made with obsidian were superior to those made with standard surgical steel, wound tensile strength, scar width, and histology were assessed in 40 adult male Sprague-Dawley rats. Ancient Scalpels Obsidian scalpels older than 2100 BC have been found in a Bronze Age. And ultimately, it could be possible to 3D print reinforced obsidian or something even better.There are several anecdotal clinical articles claiming wound healing and scar superiority using obsidian (volcanic glass) scalpels.

The handles in our range of scalpels and blades are designed to be ergonomic and easy to grip, and, like our scalpel. Whether you’re looking for high-quality stainless steel scalpel handles, surgical blade removal systems or a blade mounting bracket, you’ll find what you need in our collection.

And with AI, they could be robotically napped (though that will only raise the price – with low quantities, building a “flint-napping” robot with AI software would cost more to build than building a human). Scalpels, blades, and accessories are essential tools for many medical professionals. With more interest pushing more experimentation, perhaps a way to reinforce them will be invented. No doubt as interest in obsidian scalpels increases, there will be more research in design and manufacture, and the best design(s) become standard. 2 microns compared to a really good steel blade at 1 micron.

What would happen with something sharp in the body that couldn’t be enveloped in scar tissue? Hopefully more research will be performed, including on how to monitor for breakage, and find and retrieve them. Obsidian is used by some surgeons for scalpel blades, as well-crafted obsidian blades have a cutting edge many times sharper than high-quality steel surgical. Answer (1 of 6): The theory behind this selection is that a thinner edge is better and obsidian (or volcanic glass) can have an edge thickness down to. makers produce a program on surgical technology in ancient Egyptian. Plastic dowels are made of polyoxymethylene. The relatively inexpensive obsidian scalpel is a good substitute for an expensive diamond knife. It is ideal for applications where an extremely fine cutting action is required or where trace metals from ordinary scalpel blades cannot be tolerated. Indeed, I’m kinda curious what an ultra-sharp obsidian edge would do if left in, since the finest obsidian edges supposedly don’t leave scars. Modern obsidian scalpels look nothing like the decorative flint-knapped knives of. Obsidian is a type of volcanic glass that produces a much finer blade than conventional steel. It’s not a matter of if it will happen, but how often. Even the cheapest steel blade is unlikely to break even if a surgeon tried to do it. An obsidian blade can hold an edge of just 30 angstroms, making it sharper than any modern scalpel. To give you a point of reference, most household razor blades that are made out of steel measure between 300 and 600 angstroms.

Still, even at the same price point, they are available with what appears to be a more stable design.īut you’ve got a good point. The cutting edge of a blade can be measured in angstroms which gives you a rough idea of how sharp the knife is.
