Video-assisted thoracoscopic surgery (VATS) is a type of minimally invasive thoracic surgery performed using a small video camera mounted to a fiberoptic thoracoscope (either 5 mm or 10 mm caliber), with or without angulated visualization, which allows the surgeon to see inside the chest by viewing the video images relayed onto a television screen, and perform procedures using elongated ...
Video-assisted thoracoscopic surgery, or VATS, came into widespread use in the 1990s and early on in its development practitioners began to perform lobectomy via VATS incisions. [3] The advantage of VATS over thoracotomy is that major chest wall muscles are not divided and ribs are not spread. This leads to reductions in the intensity and ...
Parts washers were originally developed for use in automotive transmission and engine repair shops as a way to improve the function of simple soak tanks.Soak tanks are vats filled with a mixture of water and detergent, which take hours to "soften" the built-up road grime, fluids, tars and oils enough to be manually rinsed off prior to disassembly and repair.
The solution drains from the tank, and is either recycled back into the vat or is pumped to the next step of the recovery process. Vat leach units are rectangular containers (drums, barrels, tanks or vats), usually very big and made of wood or concrete, lined with material resistant to the leaching media. The treated ore is usually coarse.
Presence of frank, foul-smelling pus, which easily mixes with irrigating fluid indicates suppuration and in such cases, antral wash may be repeated once or twice a week. [ 12 ] Plain Radiological X-rays ( Water's view ) of sinuses is most specific non- invasive method of diagnosing Antral pathology.
For reconcentrating, the caustic soda was either transferred out of the boiler of the locomotive and boiled in open vats, or, rather more conveniently, by injecting superheated steam at a high enough temperature to boil off the water in solution.
Endoscopic thoracic sympathectomy (ETS) is a surgical procedure in which a portion of the sympathetic nerve trunk in the thoracic region is destroyed. [1] [2] ETS is used to treat excessive sweating in certain parts of the body (focal hyperhidrosis), facial flushing, Raynaud's disease and reflex sympathetic dystrophy.
In the two-storey Fermenting House yeast was added to large wooden temperature-controlled vats, with fermentation producing a dilute (8%) solution of alcohol . The "wash" was transferred to vats on the top floor of the three-storey Settling House, where it was allowed to settle out.
