OBSIDIAN SCALPEL SURGICAL SKIN

Today, thin blades of obsidian are placed in surgical scalpels used for some of the most precise surgery. A plasma scalpel: comparison of tissue damage and wound healing with electrosurgical and steel scalpels. Obsidian can be used to produce a cutting edge that is thinner and sharper than the best surgical steel.Effects of thermal knives on wound healing.Ancient technology in contemporary surgery.Comparison of wound-healing characteristics with feedback circuit electrosurgical generators in a porcine model.steel scalpel: a side by side comparison of cutaneous wound healing. Effects of steel scalpel, ultrasonic scalpel, CO2 laser, and monopolar and bipolar electrosurgery on wound healing in guinea pig oral mucosa. When was the scalpel first used The surgical scalpel as we know it today was invented by the Bard-Parker Company and patented in 1915.It features a specialized handle with an interchangeable blade made from modern stainless steel alloys, a concept that was inspired by the disposable shaving blades developed by King Gillette in the early 1900s.

OBSIDIAN SCALPEL SURGICAL SKIN

Comparative study of wound healing in rat skin following incision with a novel picosecond infrared laser (PIRL) and different surgical modalities.

The ophthalmology microscalpel versus standard scalpels and wound healing in a rat model.

A blinded histologic review suggested that obsidian wounds contained fewer inflammatory cells and less granulation tissue at 7 days. At 42 days, all wounds were barely detectable, thus precluding scar width analysis. It is ideal for applications where an extremely fine cutting.

At 21 days, scar width was not different in the two groups. Obsidian is a type of volcanic glass that produces a much finer blade than conventional steel. Scar width, however, was significantly less in the obsidian wounds at 7, 10, and 14 days (p < 0.005). Tensile strength of the two wound types was not different at 7, 14, 21, and 42 days.

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 by some surgeons for scalpel blades, as well-crafted.
