optic trocar
Specialized trocar with a transparent tip allowing direct visualization during insertion.
Full Definition
An optic trocar is a specialized access device featuring a transparent or clear tip that permits direct laparoscopic visualization during insertion into the abdominal cavity. This design allows surgeons to see tissues as they advance the trocar, potentially reducing the risk of injury to underlying organs and vessels. The clear tip is typically beveled and may incorporate a camera system or fiber-optic technology. Optic trocars are particularly useful for secondary port placement or in cases with suspected adhesions where blind insertion might be hazardous. However, they require adequate pneumoperitoneum for visualization and may not prevent all insertion-related injuries.
Usage
Usage note: May be spelled as 'optical trocar' in some literature; both forms are acceptable.
