Chainsaw Man Characters
A chainsaw (or chain saw) is a portable gasoline-, electric-, or battery-powered saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. It is used in activities such as tree felling, limbing, bucking, pruning, cutting firebreaks in wildland fire suppression, and harvesting of firewood. Chainsaws with specially designed bar-and-chain combinations have been developed as tools for use in chainsaw art and chainsaw mills. Specialized chainsaws are used for cutting concrete during construction developments. Chainsaws are sometimes used for cutting ice; for example, ice sculpture and winter swimming in Finland. History In surgery The origin of chain saws in surgery is debated. A "flexible saw", consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (c. 1783–1785) by two Scottish doctors, John Aitken and James Jeffray, for symphysiotomy and excision of diseased bone, respectively.

Pelviotomy
Symphysiotomy is an outdated surgical procedure in which the cartilage of the pubic symphysis is divided to widen the pelvis allowing childbirth when there is a mechanical problem. It is also known as pelviotomy, synchondrotomy. Introduction Symphysiotomy was advocated in 1597 by Severin Pineau after his description of a diastasis of the pubis on a hanged pregnant woman. Thus symphysiotomies became a routine surgical procedure for women experiencing an obstructed labour. They became less frequent in the late 20th century after the risk of maternal death from caesarean section decreased (due to improvement in techniques, hygiene, and clinical practice). Indications The most common indications are a trapped head of a breech baby, shoulder dystocia which does not resolve with routine manoeuvres, and obstructed labor at full cervical dilation when there is no option of a caesarean section. In some Irish cases, caesarean sections were performed after symphysiotomies. Currently the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Joseph Buford Cox
Joseph Buford Cox (1905 – August 10, 2002), was an American inventor and businessman. He invented what is now known as the chipper type chain for chain saws. He based his design on the C-shaped jaws of the larva of the timberman beetle. Cox watched the destructive larvae of the timber beetle (Ergates spiculatus) for many hours. The beetle's cutting action was left and right, side to side, rather than scratching or burrowing straight ahead. Cox adapted this concept to a new chain saw of his own design put into production during the late 1940s. Joseph and his wife, Alice, founded "The Oregon Saw Chain Co." in 1947. Cox later started a small casting company called OMARK, now known as "Omark Industries". In time, Oregon Saw Chain became a subsidiary of Omark Industries which was in turn acquired in 1985 by Blount, Inc., of Montgomery, Alabama. Blount merged in 1999 with Lehman Brothers Merchant Banking Partners Trilantic Capital Partners (Trilantic) is a global private equity firm fo ...

Osteotome
An osteotome is an instrument used for cutting or preparing bone. Osteotomes are similar to a chisel but bevelled on both sides. They are used today in plastic surgery, orthopedic surgery and dental implantation. The chain osteotome, originally referred to simply as the osteotome, was invented by the German physician Bernhard Heine in 1830. This device is essentially a small chainsaw. See also *Instruments used in general surgery There are many different surgical specialties, some of which require very specific kinds of surgical instruments to perform. General surgery is a specialty focused on the abdominal contents, as well as the thyroid gland, and diseases involving ... References {{Surgical instruments Orthopaedic instruments ...

Bernhard Heine
Bernhard Heine (August 20, 1800, Schramberg (Black Forest) – July 31, 1846, Glockenthal near Thun (Switzerland)) was a German physician, bone specialist and the inventor of the osteotome, a medical tool for cutting bones. Apprenticeship in Würzburg Bernhard Heine was born on August 20, 1800 as the son of a tanner in Schramberg. At the age of ten (according to other references, thirteen) years he was apprenticed to his uncle Johann Georg Heine in Würzburg as an orthopaedic mechanic. Without any enrolment he later attended lectures in medicine at the University of Würzburg. After a number of journeys he took over his own department in his uncle's orthopaedic institute. When Johann Georg moved to the Netherlands in 1829, Bernhard - together with his cousin Joseph Heine - became the head of the Würzburg institution. In 1837 Bernhard Heine married his cousin (Johann Georg's daughter) Anna Heine (born 1801). Inventing the osteotome In 1830, after years of research and dev ...
