trocar
의미: A sharp-pointed surgical instrument fitted inside a cannula, used to puncture a body cavity or create a port for inserting instruments during minimally invasive surgery.
Trocars are essential to laparoscopic (keyhole) surgery, where they create the small incisions through which a camera and instruments are passed into the abdomen. The instrument consists of a pointed obturator housed within a sheath; once the puncture is made, the obturator is removed and the sheath remains as an access port. The term is highly specialised and appears almost exclusively in surgical literature, operating theatre manuals, and medical device catalogues.
