#OBSIDIAN SCALPEL WOUND SKIN#

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). Obsidian is produced from felsic lava, rich in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. The comprehensive Swann-MortonВ® range of surgical blades, handles, stitch cutters and scalpels is the result of dedication to quality of the highest standard and the latest technology.Features and Benefits:Unsurpassed Sharpness, a blade that is not only initially sharper, but remains sharp - is the result of over 50 years commitment to product innovation. Tensile strength of the two wound types was not different at 7, 14, 21, and 42 days. Obsidian (/ b s d i n /) is a naturally occurring volcanic glass formed when lava extruded from a volcano cools rapidly with minimal crystal growth.It is an igneous rock.

#OBSIDIAN SCALPEL WOUND SKIN#

Each rat received two parallel 8-cm dorsal skin incisions, one with an obsidian scalpel and the other with a surgical steel scalpel (no. 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.

There are several anecdotal clinical articles claiming wound healing and scar superiority using obsidian (volcanic glass) scalpels. A comparison of obsidian and surgical steel scalpel wound healing in rats.
