The Lancet

The Lancet is a weekly peer-reviewed general medical journal. It is one of the world's oldest and best known general medical journals, and has been described as one of the most prestigious medical journals in the world.

The Lancet was founded in 1823 by Thomas Wakley, an English surgeon who named it after the surgical instrument called a lancet, as well as after the architectural term "lancet arch", a window with a sharp pointed arch, to indicate the "light of wisdom" or "to let in light".

The Lancet publishes original research articles, review articles ("seminars" and "reviews"), editorials, book reviews, correspondence, as well as news features and case reports. The Lancet has been owned by Elsevier since 1991. As of 2015, the editor-in-chief is Richard Horton. The journal has editorial offices in London, New York, and Beijing.

Impact

In the 2014 Journal Citation Reports, The Lancet was ranked second among general medical journals, (with an impact factor of 45), after The New England Journal of Medicine (impact factor of 56).

Scalpel

A scalpel, or lancet, is a small and extremely sharp bladed instrument used for surgery, anatomical dissection, and various arts and crafts (called a hobby knife). Scalpels may be single-use disposable or re-usable. Re-usable scalpels can have permanently attached blades that can be sharpened or, more commonly, removable single-use blades. Disposable scalpels usually have a plastic handle with an extensible blade (like a utility knife) and are used once, then the entire instrument discarded. Scalpel blades are usually individually packed in sterile pouches but are also offered non-sterile. Double-edged scalpels are referred to as "lancets".

Scalpel blades are usually made of hardened and tempered steel, stainless steel, or high carbon steel; in addition, titanium, ceramic, diamond and even obsidian knives are not uncommon. For example, when performing surgery under MRI guidance, steel blades are unusable (the blades would be drawn to the magnets, or may cause image artifacts). Historically, the preferred material for surgical scalpels was silver, on account of its antimicrobial properties (although the mechanics were not understood at the time). Scalpel blades are also offered by select manufacturers with a zirconium nitride-coated edge to improve sharpness and edge retention. Others manufacture blades that are polymer coated to enhance lubricity during a cut. Alternatives to scalpels in surgical applications include electrocautery and lasers.
