The handle of the scalpel blade is the part of the instrument that is gripped by the surgeon. It is often used for creating large incisions through thick skin, and for soft tissue dissection in surgery. 10 blade with a curved cutting edge and a flat unsharpened back edge.
#Obsidian scalpel used in surgery skin
It is utilized in a variety of surgical procedures, including the excision of small skin lesions, organ biopsy, and fine neurological applications. It is one of the most popular blades in surgery because its shape is ideal for making short and precise incisions. 15 blade has a small, curved cutting edge. 12 blade is used for disarticulating small joints, such as those between the metacarpels, metatarsals, and phalanges during digit amputation. It is sometimes utilized as a suture cutter. 12 blade is a small, pointed, crecent-shaped blade sharpened along the inside edge of the curve. It has a strong, pointed tip, making it ideal for stab incisions and precise, short cuts in shallow, recessed opening major blood vessels for catheter insertion, removing the mop ends of torn cruciate ligaments, and for meniscectomy. 11 blade is an elongated, triangular blade sharpened along the hypotenuse edge. It is generally used for making large incisions in the skin and subcutaneous tissue, as well as cutting other soft tissue. 10 blade, with its large, curved cutting edge, is one of the more traditional blade shapes used in surgery. Blades also vary by length and shape of the cutting edge, with each blade suited to different purposes. Scalpel blades come in a variety of sizes, commonly referred to by the blade number.

The main differences relate to the overall size of the blade or the shape of the cutting edge. Scalpel blades are available in a variety of different styles.
#Obsidian scalpel used in surgery how to
In this module we will discuss how to safely arm, disarm, and pass a scalpel, as well as how to grip a scalpel and the methods of cutting with a scalpel blade. It is very important to learn how to handle a scalpel correctly, whether using it, handing it to someone, or changing the blade. However, if used incorrectly, scalpels pose a danger to both the patient and the surgical team.
However, I fear that these methods could possibly weaken the (already delicate) structure of the obsidian.Scalpels are an important tool for performing surgical approaches and tissue dissections. 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
