A new camera trocar for gasless endoscopic thyroid surgery.
A commercially available camera trocar diminishes the working space because of its high profile and is not proof against blood stain. The authors designed a new camera trocar for gasless endoscopic thyroid surgery. The new trocar consists of a shaft for a 5-mm endoscope as well as a disc 18 mm in diameter and 2 mm thick. The trocar is inserted from an adjacent 3-cm working port, pushed out to an incision for a 5-mm endoscope, and placed with the shaft up and the disc down. Because of its disc, the trocar is designed to be proof against blood stain and to maintain more working space. The newly designed trocar might be very useful for gasless endoscopic thyroid surgery as well as other gasless surgical procedures.
