Regular endoscopic instruments come in 5‐ and 10 mm diameters. For most small animal applications, 5‐mm instruments are adequate. Common exceptions are the use of 10‐mm Babcock or Duval forceps for grasping thicker tissues such as the stomach wall. Mini‐laparoscopic instrumentation is now available for small dogs and cats weighing less than 10 kg. These come in 2‐, 2.3‐, and 3 mm diameter sizes, depending on the manufacturer. The available shaft length depends on the instrument diameter and should be chosen based on patient size, with shorter shafts used for small patients and longer shafts for large or obese patients. Using a shaft that is either too long or too short for the patient can be awkward for the operator and can inhibit the ability to reach tissues inside the body cavity. Short and long shaft lengths vary by manufacturer but are similar. In general, 5‐ and 10‐mm instruments range from 33 to 36 cm for the short length and from 43 to 45 cm for the long length. Mini‐laparoscopy instruments range from 20 to 30 cm in length.
