trocar
Pronunciation: TROH-kar
A surgical instrument used to create initial access ports for laparoscopic instruments.
Full Definition
A trocar is a sharp-pointed instrument used to puncture the abdominal wall and establish pneumoperitoneum for laparoscopic surgery. It consists of a sharp obturator within a cannula that remains in place as a working port. Trocars come in various sizes (5mm, 12mm, 15mm) and may be reusable or disposable. Proper trocar placement is critical for safe laparoscopic access and instrument maneuverability.
Usage
Usage note: Always specify trocar size in millimeters when documenting procedures.
