surgical retractors
DESCRIPTION
A retractor is a surgical instrument by which a surgeon can either actively separate the edges of a surgical incision or wound, or can hold back underlying organs and tissues, so that body parts under the incision may be accessed. Retractors are used for holding the incision open to provide exposure to thesurgical site. Smaller types held by the fingers or hands retract skin and subcutaneous tissue in shallow surgical areas. Larger, heavier models retract muscle tissue and organs in deeper surgical sites. The two are each available in many shapes, sizes, and styles. The general term retractor usually describes a simple handheld steel tool possessing a curved, hooked, or angled blade fitted with a comfortable handle, that when in place maintains the desired position of a given region of tissue. These simple retractors may be handheld, clamped in situ, or suspended at the end of a robotic arm. The term retractor is also informally used, though, to describe the distinct, hand-cranked devices such as rib spreaders (also known as distractors) with which surgeons may forcefully drive tissues apart to obtain the exposure. Some retractors are held in place by an assistant while the surgeon completes the procedure, while self-retaining retractors require no assistant to hold them. Self-retaining retractors are held open by their own action and may be used in conjunction with the hand held retractors. Examples of retractors: Richardson- Eastman, Mayo, Jansen Mastoid, Weitlaner, Cerebellum, Gelpi, Volkman Rake, Green Goiter, Army-Navy, Deaver. The retractor was invented by Abu al-Qasim, an Islamic physician, over 1000 years agoTRANSCRIPT
