Specification of Trocar For Animal - Cow
A trocar (or trochar) is a medical or veterinary device that is made up of an obturator (which may be a metal or plastic sharpened or non-bladed tip), a cannula (basically a hollow tube), and a seal. Trocars are placed through the abdomen during laparoscopic surgery. The trocar functions as a portal for the subsequent placement of other instruments, such as graspers, scissors, staplers, etc. Trocars also allow the escape of gas or fluid from organs within the body.
Trocars are widely used by veterinarians not only for draining hydrothorax, ascites, or for introducing instruments in laparoscopic surgery, but for acute animal-specific conditions as well. In cases of ruminal tympany (bloat) in cattle, a wide-bore trocar may be passed through the skin into the rumen to release trapped gas.[7]In dogs, a similar procedure is often performed for patients presenting with GDV (gastric dilatation-volvulus) in which a wide-bore trocar is passed through the skin into the stomach to immediately decompress the stomach. Depending on the severity of clinical signs on presentation, this is often performed after pain management has been administered but prior to general anaesthesia. Definitive surgical treatment involves anatomical repositioning of the stomach and spleen followed by a right-sided gastropexy.[8] Depending on the severity, partial gastrectomy and/or splenectomy may be indicated if the relevant tissues have necrosed due to ischemia caused by torsion/avulsion of the supplying vasculature. 72-hour post-operative supportive care, fluid therapy and ECG monitoring for cardiac arrhythmias is highly recommended.
