A plasma scalpel: comparison of tissue damage and wound healing with electrosurgical and steel scalpels. Obsidian is used by some surgeons for scalpel blades, as well-crafted.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. The surgical knife, one of the earliest surgical instruments, has evolved over 10 millennia. Effects of steel scalpel, ultrasonic scalpel, CO2 laser, and monopolar and bipolar electrosurgery on wound healing in guinea pig oral mucosa. Because stones such as flint, jade, and obsidian have sharp edges, they were first used to make knives in the Stone Age.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. 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). Tensile strength of the two wound types was not different at 7, 14, 21, and 42 days. They are extremely sharp, even sharper than surgical steel scalpels. Each rat received two parallel 8-cm dorsal skin incisions, one with an obsidian scalpel and the other with a surgical steel scalpel (no. The obsidian rock will show a unique flaking pattern that tapers to the blade. Animal experiments have shown the tensile strength of obsidian produced wounds to be equal to or greater than that of wounds produced by steel scalpels after 14 days of healing. ceramic blades, diamond, and obsidian blades would be used alternatively. Crabtree have been used in experimental microsurgery with excellent results. Most disposable scalpels are designed for single-use. Sometimes they may be referred to as a 'surgeons scalpel.' They may be single-use, disposable or re-usable. 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. A 'surgical scalpel' and a 'medical scalpel' are the same things. N2 - There are several anecdotal clinical articles claiming wound healing and scar superiority using obsidian (volcanic glass) scalpels. ![]() T1 - A comparison of obsidian and surgical steel scalpel wound healing in rats.
