A 10 blade is larger - a 15 blade is smaller. The two most commonly used scalpel blades are a #15 and a #10. There are a number of different blade shapes for doing different tasks and are referred to by that number when requesting a fresh scalpel for a different task.Ī #10 scalpel blade is a very common slightly curved cutting edge. A blade used internally may even be replaced as the surgery goes along. Other scalpel handles with replaceable blades are used. The “skin-knife” makes one cut then is taken off the surgical Mayo stand & never used again. The term scalpel might also be used as a non steel cutting device as electrical scalpel or for just plain esoterica obsidian scalpel. The handles and the blades come in various sizes and some handles are bent for convince. Normally now in surgery it is a disposable steel blade attached to a sterilizable handle. Different situations calls for different sharpness and depth of incision. If the surgeon has to be a little more delicate or has to make a curving incision with a narrow radius, then a blade that is narrower and has a smaller cutting surface (#15) is great.
#Obsidian scalpel made by patient skin
If one needs to make a deep, long incision like a skin incision in an obese patient then a wide, positively curved scalpel (#22) works well. If the goal is to make a deep, but narrow “stab” incision in skin (for instance to insert a 5mm laparoscopic trocar through the abdominal wall) then a blade that is long, narrow and comes to a point (#11 blade) is perfect.
You would use different instruments to cut different materials, right? A saw if you are cutting a piece of wood, a serrated knife to slice bread, and a carving knife to cut up turkey. There is a scalpel made for just about any of the hundreds of different situations that various types of surgeries present. There are many types of scalpel blades that vary in length, width, length of cutting surface and overall shape. These days more and more scalpels are made of plastic with a permanently mounted blade attached. Surgical sharpness is just sharp enough for surgery and sharp enough to cause no harm by being too blunt and cheap enough to be disposable. However, I fear that these methods could possibly weaken the (already delicate) structure of the obsidian.A scalpel is the classical name in English for pretty much anything makes an incision. 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. 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. 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.
Now these scalpels are pretty fragile, with some of them having a thickness of the order of 0.1 mm. 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
