The 3 different blade definitions
The 3 different blade definitions Posted on May 5, 2012 Most surgical scissors are manufactured with different blade types this all depends on the particular surgical practice being done by the doctor. The 3 different blade definitions are… Stainless Blades – The most common is the surgical scissors with stainless steel blades. The entire scissor is manufactured out of the exact same metal (stainless steel) and you should notice any ring colors. Tungsten Carbide Blades – Inserted only along the cutting surfaces of the blade is the metal tungsten carbide (A.K.A TC). These metal strips are much harder than stainless steel. When sharpened, this type of surgical scissor blades stay more sharp for a longer period of time and are attached to the stainless scissor by welding or vacuum brazing. These T.C. insert strips cannot be replaced once they become sharpened down. Tungsten carbide surgical scissors have gold rings to distinguish this design. Black Handled Surgical scissors – These surgical scissors are known as micro grind or super cut surgical scissors in the industry. The sharpening practice that is used to make these medical instruments is what makes it truly unique. This scissor will “knife” through whatever you will bring to it. All other surgical scissors crush, resulting in cutting, whereas the black handled scissor slices tissue. Black handled surgical scissors require special sharpening techniques using special medical equipment and must be re-sharpened three to four times a year. The unique features of these surgical scissors are the black colored rings. Gold Handled surgical scissors have cutting blades made of tungsten carbide. Becuase its rough and more harder, TC stay sharper longer. Inspect TC blades for cracks before tray assembly. If you see a crack, then send it back right away so the manufacture can replace it with the warranty.
