![]() However, I fear that these methods could possibly weaken the (already delicate) structure of the obsidian. I have considered subjecting the scalpel to strong dose of UV radiation or perhaps 'cleaning' the scalpel with Povidone-Iodine (Betadine). I did try looking up the structure that obsidian assumes at the molecular level, with the hope that the knowledge would help me narrow down possible sterilization methods I could use here, but I drew a blank there as well. > 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 scalpels, the cutting edge of the blade. Biomechanics is the study of the physical properties of all biological materials (including. Knowing how delicate this thing is, I doubt conventional methods (such as autoclaving it) used to sterilize surgical tools could be safely applied in this case.Īs the use of obsidian blades in surgery is relatively new, I'm not surprised that I can't find any literature dealing with the sterilization of obsidian blades online. Answer (1 of 2): Is obsidian sharper than a scalpel Yes, obsidian is sharper than a scalpel. Obsidian scalpel vs steel cut under microscope verification. I don't actually plan on operating on someone with this, but all the same, I'd like to identify potential methods to sterilize such a blade. Obsidian knives have been tested for use as surgical scalpels but arent currently licensed. Now these scalpels are pretty fragile, with some of them having a thickness of the order of 0.1 mm. Obsidian knife blades: overkill for slicing your sandwich. A blinded histologic review suggested that obsidian wounds contained fewer inflammatory cells and less granulation tissue at 7 days.I recently came across this article on the use of obsidian scalpels in surgery: How Stone Age blades are still cutting it in modern surgery They are designed with a knurled collar which tightens up and loosens down on the aluminum collet. Generally, the blades have a length of 146mm. The scalpels are integrated with number 1 and number 2 blades. There are traditions of obsidian weapons in many cultures and they refine it to pretty fine shapes. This is because the scalpels have blades that can hold the edge a long time as compared to utility knives. ![]() At 42 days, all wounds were barely detectable, thus precluding scar width analysis. Remember how ridiculous the obsidian looked in that show Like they thought the audience would only recognize it if it was thick and jagged. 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). 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 scalpels, the cutting edge of the blade being only about 3 nanometers thick. and it has been used experimentally as surgical scalpel blades. ![]() Tensile strength of the two wound types was not different at 7, 14, 21, and 42 days. Obsidian is a naturally occurring volcanic glass formed when lava extruded from a volcano. Each rat received two parallel 8-cm dorsal skin incisions, one with an obsidian scalpel and the other with a surgical steel scalpel (no. From stone and obsidian knives, to stainless steel reusable handles, the surgical scalpel has remained an important tool for surgeons throughout human. 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. Obsidian is used in cardiac surgery, as well-crafted obsidian blades have a cutting edge many times sharper than high-quality steel surgical scalpels. ![]() There are several anecdotal clinical articles claiming wound healing and scar superiority using obsidian (volcanic glass) scalpels. Compared to the steel blades, these tools are more durable and can be used in situations where. Ceramic, titanium, diamond, sapphire, and obsidian are other less common options. A comparison of obsidian and surgical steel scalpel wound healing in rats. The modern steel blades are sharper than the obsidian ones. Silver was historically the material of choice for surgical scalpels, but today, surgical scalpel blades are usually made from stainless steel, tempered steel or high carbon steel.
