A<unk> , also known as Finochietto retractor, is a type of retractor specifically designed to separate<unk> s in thoracic surgery. Rack-and-pinion-type stainless steel<unk> s (with a thumb-screw to lock it in place) were an innovation introduced by French surgeon Theodore Truffier in 1914. This was modified in 1936 by Argentinian surgeon Enrique Finochietto to have fenestrated blades (blades with "windows") and a hand-cranked lever to both separate the arms in a staged fashion and lock them in place at each stop. The Burford–Finochietto<unk>  has replaceable blades. The Tuffier and especially the Burford–Finochietto (and its variants) are ubiquitous in open thoracic surgery. Recently, a new intelligent, automated<unk>  in development demonstrated results superior to the Finochietto-style retractors.
