摘要：
A cannula suitable for use in minimally invasive surgery is improved with a highly polished and very smooth luminal wall and/or LED's or other light sources focused at particular angles relative to the axis of the cannula. The devices provide for improved lighting and/or reduced lighting requirements for cannulas used for minimally invasive surgery.
