Laparoscopic Instruments - Common Surgical Instruments
Many instruments are similar to those used in open surgery, adapted to fit through narrow ports placed through the skin. Laparoscopic work is then conducted via the ports.
• Camera: The camera is the handheld component and connects to a variety of lenses. There are usually settings for focus and white balance.
• Lens: Available in multiple viewing angles to achieve better visualization of anatomical structures. May require occasional defogging.
• Light Source: Fiber optic cable connects to lens and illuminates field of vision. Caution around internal structures as light output can be hot.
• Insufflator: Injects carbon dioxide into the abdominal cavity to create a working space for trocar placement and surgical procedures.
• Veress Needle: One method of achieving pneumoperitoneum. Consists of blind placement of needle into abdomen and subsequent injection of gas.
• Trocars: Transabdominal working ports where laparoscopic instruments are inserted. Also for insufflation or removal of specimens. Available in multiple sizes, e.g., 5, 10, and 12 mm.
• Laparoscopic Instruments: Handheld and shafted implements used to work through trocars. Can perform grasping, retracting, cutting, cauterizing, and other functions.
