Instruments may be equipped with insulation and a connection for a monopolar electrosurgical device at the surgeon's preference. If modular instruments are chosen, at least one ratcheted and one nonratcheted handle should be included. Trays designed specifically for sterilization and safe storage of delicate endoscopic instruments are available and highly recommended (ssss1). Often, the camera, telescopes, light cable, and insufflation tubing are packaged separately from the rest of the instruments.
4.2 Trocars and Cannulas
Nicole J. Buote
Key Points
Trocar assembly includes a cannula, seal, and obturator.
Veress needle use for insufflation requires blind insertion of a specially designed needle for CO2 insufflation before trocar placement.
In the direct insertion technique, the primary trocar is placed without preinsufflation with either a bladed trocar or an optical trocar.
The Hasson technique requires a mini‐laparotomy with visualization of intraabdominal structures before placement of the trocar.
