In a swaged suture the thread is of narrower diameter than the needle, whereas it protrudes on both sides in an eyed needle. Being narrower, the thread in a swaged suture has less drag when passing through tissue than the needle, and, not protruding, is less likely to traumatize friable tissue, earning the combination the designation "atraumatic".
There are many different surgical specialties, some of which require specific kinds of surgical instruments to perform.. 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.
Atraumatic restorative treatment (ART) [1] is a method for cleaning out tooth decay (dental caries) from teeth using only hand instruments (dental hatchet and spoon-excavator) and placing a filling. It does not use rotary dental instruments ( dental drills ) to prepare the tooth and can be performed in settings with no access to dental equipment.
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 ...
Debakey forceps. Debakey forceps are a type of atraumatic tissue forceps used in vascular procedures to avoid tissue damage during manipulation. They are typically large (some examples are upwards of 12 inches (36 cm) long), and have a distinct coarsely ribbed grip panel, as opposed to the finer ribbing on most other tissue forceps.
Catgut suture is straw-colored, and is available in sizes USP 6-0 (1 metric) to USP 3 (7 metric). Although the name implies the usage of guts of cats, there is no record of feline guts being used for this purpose. The word catgut is derived from the term kitgut or kitstring (the string used on a kit, or fiddle).
It is possible that this is the result of recent advances in suture technology, along with increasingly risk-conscious surgical practice. Certainly modern synthetic sutures are more predictable and less prone to infection than catgut , silk and linen , which were the main suture materials used up to the 1990s.
Hemostats. A hemostat (also called a hemostatic clamp; arterial forceps; and pean, after Jules-Émile Péan) is a tool used to control bleeding during surgery. [1] Similar in design to both pliers and scissors, it is used to clamp exposed blood vessels shut.
