Prosthetics :: essays research papers

submissionProsthetics is the branch of surgery dealing with mechanical devices practiced to reproduce the stochastic variable and function of missing luggage compartment parts. Prosthetics is the replacement of faulty or amputated body parts with dummy body parts. Artificial limbs imbibe been in use since at least 300 BC. In AD 1509 German knight, Gtz von Berlichingen, called Gtz of the Iron Hand, wore an artificial bridge player with jointed fingers. Early in the 19th century a German prosthesist construct a hand with fingers that could be flexed or extended and that could hold light objects, such as a pen or a hat. Before World fight I (1914-1918), wood was considered the outperform substance for making artificial legs, entirely later an aluminum alloy called Duraluminum, and more recently fiber materials, have made artificial limbs both lightweight and strong. In recent years, the fabrication of prosthetic devices has developed into a science. Artificial limbs with fu nctioning joints can take for granted natural motion. Hip joint prostheses can provide virtually normal mobility for people with damaged hip joints.HistoryArtificial limbs, in mavin form or other, have been in use from ancient times. In 1885, a specimen was discovered in a tomb at Capua, Italy, along with other relics dating from 300BC. The celebrated artificial hand create in 1509 for the German knight Gotz von Berlichingen, who was called Gotz of the Iron Hand, weighed about 1.4 kg (3 lb.) and had provide fingers so constructed as to be able to grasp a stigma or lance. The hand is in the Nrnberg Museum and is still in workings order. Early in the 19th century a German prosthesist built a hand with fingers that could be flexed or extended without assistance and all the aforementioned(prenominal) could still close to hold light objects, such as a pen, a handkerchief, or a hat. In 1851, a French prosthesist invented an artificial arm fitted with a wooden hand and attached to a lather socket that fitted the stump firm. The fingers were half-closed, the feel pivoted on a pin and could press firmly against the fingertips by a concealed, strong rubber band the grasp of the thumb could be operated by a mechanism attached to the opposite shoulder. The same inventor devised a leg that reproduced a natural gait and elongated the stride.TechnologyBefore World War I, wood was universally considered the best substance for making artificial legs. Prosthetic devices made of leather strengthened with metal bands tended to lose their shape and were therefore unsatisfactory.
