General surgery is a specialty focused on the abdomen; the thyroid gland; diseases involving skin, breasts, and various soft tissues; trauma; peripheral vascular disease; hernias; and endoscopic procedures. Instruments can be classified in many ways, but, broadly speaking, there are five kinds of instruments. Cutting and dissecting instruments
Hand surgery emerged as a specialty during World War II, and the tools used by early hand surgeons remain in common use today, and many are identified by the names of those who created them. [4] Individual tools have diverse history development. Below is a brief history of the inventors and tools created for five commonly used surgical tools.
Sutures are placed by mounting a needle with attached suture into a needle holder. The needle point is pressed into the flesh, advanced along the trajectory of the needle's curve until it emerges, and pulled through. The trailing thread is then tied into a knot, usually a square knot or surgeon's knot.
Tactical Combat Casualty Care (TCCC or TC3), formerly known as Self Aid Buddy Care, [1] is a set of guidelines for trauma life support in prehospital combat medicine published by the United States Defense Health Agency. They are designed to reduce preventable deaths while maintaining operational success.
During surgery, a surgical needle or other sharp instrument may inadvertently penetrate the glove and skin of operating room personnel; [7] scalpel injuries tend to be larger than a needlestick. Generally, needlestick injuries cause only minor visible trauma or bleeding; however, even in the absence of bleeding the risk of viral infection remains.
The procedure was first described in 1805 by Félix Vicq-d'Azyr, a French surgeon and anatomist. [3] A cricothyrotomy is generally performed by making a vertical incision on the skin of the throat just below the laryngeal prominence (Adam's apple), then making a horizontal incision in the cricothyroid membrane which lies deep to this point.
A standard general surgical needle holder, with a ratchet handle lock. Two specialty needle holders, Mathieu needle holder (above) and Castroviejo needle holder (below). A needle holder, also called needle driver or needle forceps, is a surgical instrument similar to a hemostat, used by doctors and surgeons to hold and push a suturing needle when performing wound closure, ligation and other ...
Penetrating trauma is an open wound injury that occurs when an object pierces the skin and enters a tissue of the body, creating a deep but relatively narrow entry wound. In contrast, a blunt or non-penetrating trauma may have some deep damage, but the overlying skin is not necessarily broken and the wound is still closed to the outside ...
