Jean-Louis Petit (surgeon)
Jean-Louis Petit (13 March 1674 – 20 April 1750) was a French surgeon and the inventor of a screw-type tourniquet. He was first enthusiastic about anatomy and received a master's certificate in surgery in Paris in 1700. He became a member of the French Royal Academy of Sciences in 1715 and was named director of the French Royal Academy of Surgery by the king when it was created in 1731. He acquired great notoriety because of his skill and experience, thanks to his case reports of hemorrhage Bleeding, hemorrhage, haemorrhage or blood loss, is blood escaping from the circulatory system from damaged blood vessels. Bleeding can occur internally, or externally either through a natural opening such as the mouth, nose, ear, urethra, ..., Lacrimal apparatus, lacrimal fistula and operation on the frenum, for his treatise on bone diseases and especially for his general treatise on surgical operations, on which he worked for 12 years and which was finished after his death by Fran ...

Tourniquet
A tourniquet is a device that is used to apply pressure to a limb or extremity in order to create ischemia or stopping the flow of blood. It may be used in emergencies, in surgery, or in post-operative rehabilitation. A simple tourniquet can be made from a stick and a rope, but the use of makeshift tourniquets has been reduced over time due to their ineffectiveness compared to a commercial and professional tourniquet. This may stem the flow of blood, but side effects such as soft tissue damage and nerve damage may occur. History During Alexander the Great’s military campaigns in the fourth century BC, tourniquets were used to stanch the bleeding of wounded soldiers. Romans used them to control bleeding, especially during amputations. These tourniquets were narrow straps made of bronze, using only leather for comfort. In 1718, French surgeon Jean Louis Petit developed a screw device for occluding blood flow in surgical sites. Before this invention, the ''tourniquet' ...

French Academy Of Sciences
The French Academy of Sciences (, ) is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the academy), it is one of the five Academies of the . __TOC__ History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque nationale de France, Bibliothèque Nationale, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the academy's existence were relatively informal, since no statutes had as yet been laid down for the ins ...

Louis XV Of France
Louis XV (15 February 1710 – 10 May 1774), known as Louis the Beloved (), was King of France from 1 September 1715 until his death in 1774. He succeeded his great-grandfather Louis XIV at the age of five. Until he reached maturity (then defined as his 13th birthday) in 1723, the kingdom was ruled by his grand-uncle Philippe II, Duke of Orléans, as Régence, Regent of France. André-Hercule de Fleury, Cardinal Fleury was chief minister from 1726 until his death in 1743, at which time the king took sole control of the kingdom. His reign of almost 59 years (from 1715 to 1774) was the second longest in the history of France, exceeded only by his predecessor, Louis XIV, who had ruled for 72 years (from 1643 to 1715). In 1748, Louis returned the Austrian Netherlands, won at the Battle of Fontenoy of 1745. He ceded New France in North America to Great Britain and Spain at the conclusion of the disastrous Seven Years' War in 1763. He incorporated the territories of the Duchy of Lorr ...

Hemorrhage
Bleeding, hemorrhage, haemorrhage or blood loss, is blood escaping from the circulatory system from damaged blood vessels. Bleeding can occur internally, or externally either through a natural opening such as the mouth, nose, ear, urethra, vagina, or anus, or through a puncture in the skin. Hypovolemia is a massive decrease in blood volume, and death by excessive loss of blood is referred to as exsanguination. Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties (by comparison, blood donation typically takes 8–10% of the donor's blood volume). The stopping or controlling of bleeding is called hemostasis and is an important part of both first aid and surgery. Types * Upper head ** Intracranial hemorrhage — bleeding in the skull. ** Cerebral hemorrhage — a type of intracranial hemorrhage, bleeding within the brain tissue itself. ** Intracerebral hemorrhage — bleeding in the brain caused by th ...

Lacrimal Apparatus
The lacrimal apparatus is the physiological system containing the Orbit (anatomy), orbital structures for tears, tear production and drainage.Cassin, B. and Solomon, S. ''Dictionary of Eye Terminology''. Gainesville, Florida: Triad Publishing Company, 1990. It consists of: * The lacrimal gland, which secretes the tears, and its excretory ducts, which convey the fluid to the surface of the eye; it is a j-shaped serous gland located in lacrimal fossa. * The lacrimal canaliculi, the lacrimal sac, and the nasolacrimal duct, by which the fluid is conveyed into the cavity of the nose, emptying anterioinferiorly to the inferior nasal conchae from the nasolacrimal duct. * The innervation of the lacrimal apparatus, which involves both a Sympathetic nervous system, sympathetic supply through the Internal carotid plexus, carotid plexus of nerves around the internal carotid artery, and parasympathetic nervous system, parasympathetically from the lacrimal nucleus of the facial nerve.

Fistula
In anatomy, a fistula (: fistulas or fistulae ; from Latin ''fistula'', "tube, pipe") is an abnormal connection (i.e. tube) joining two hollow spaces (technically, two epithelialized surfaces), such as blood vessels, intestines, or other hollow organs to each other, often resulting in an abnormal flow of fluid from one space to the other. An anal fistula connects the anal canal to the perianal skin. An anovaginal or rectovaginal fistula is a hole joining the anus or rectum to the vagina. A colovaginal fistula joins the space in the colon to that in the vagina. A urinary tract fistula is an abnormal opening in the urinary tract or an abnormal connection between the urinary tract and another organ. An abnormal communication (i.e. hole or tube) between the bladder and the uterus is called a vesicouterine fistula, while if it is between the bladder and the vagina it is known as a vesicovaginal fistula, and if between the urethra and the vagina: a urethrovaginal fistu ...

Frenum
A frenulum or frenum (: frenula or frena, from the Latin ''frēnulum'', "little bridle", the diminutive of ''frēnum'') is a small fold of tissue that secures the motion of a mobile organ in the body. In human anatomy Frenula on the human body include several in the mouth, some in the digestive tract, and some connected to the external genitalia. *Brain: '' Frenulum of superior medullary velum'' or ''frenulum veli'' *Digestive tract: ''frenulum valvae ileocaecalis'' *Oral tissue: Frenula of the mouth include the frenulum of the tongue or ''frenulum linguae'' under the tongue, the '' frenulum labii superioris'' inside the upper lip, the '' frenulum labii inferioris'' inside the lower lip, and the buccal frena which connect the cheeks to the gum. These can easily be torn by violent blows to the face or mouth, thus a torn frenulum is sometimes a warning sign of physical abuse. *Penile tissue: The word ''frenulum'' on its own is often used for the penile frenulum or ''fre ...
