embalming
An embalming surgeon at work on a soldier's body during the American Civil War.
In modern embalming, a trocar is a long, hollow needle used during the cavity treatment phase of the procedure.1
Embalmers use this instrument to puncture the body cavity to remove internal gases and fluids. Once the cavity contents are drained, the trocar is used to inject a preservative cavity fluid—typically a mixture based on Formalin—to help preserve the internal organs and prevent the body from shriveling or discoloring during the period it is viewed by mourners.12
