Here is a detailed model of a set of arthroscopy tools used in all types or arthroscopy procedures. They were built to scale using real-word measurements and actual tools were used as a reference. They were created in 3DS MAX 2011 and use standard Mentalray materials. The parts are intelligently named and grouped. Object pivot points are placed where they should be for logical animation. When possible, parametric objects are left un-collapsed so that you can adjust and animate them, when desired. The 3DS MAX version has cables and tubes that are parametric and have adjustable/animatable bend modifiers on them so you can shape them as you wish.
