Trocar
(redirected from trocars)

   Also found in: Dictionary/thesaurus, Medical, Wikipedia 0.01 sec.
Trocar 

a medical instrument for piercing the wall of the abdominal or thoracic cavity and extracting an exúdate or transudate. The trocar consists of a handle onto which tubes 1–3 mm in diameter are screwed. The sharp end of a mandrin that runs through the tube protrudes from it. The trocar is sterilized before use by boiling. After the skin is pierced under local anesthesia, the mandrin is withdrawn by means of the handle, and the fluid flows out through the tube. A drain may be inserted through this tube to permit a constant flow of fluid.
