Answers: The trocar is the instrument inside the cannula or sleeve used to insert it, and not the sleeve itself. (That is a common mistake among doctors and nurses and techs who should know better.) The trocar may be sharp or blunt or even hold a moving blade.
Sleeves can be 2,3,4,5,7,,8,9,10.11 or 12 mm (maybe even larger) in inside diameter. The outside diameter of the sleeve is usually 1 mm larger. They can be long or short from 8cm to 25 cm contained by total length. The sleeve is mobile in and out so the portion above the skin may be as little as 4 cm.
Those next to trocar locks to hold the trocar into the cannula are usually 10-11 mm.
