Abstract
Endoscopic light refraction imaging techniques are described for configuring a viewing trocar and/or angled endoscope with a light refracting element, such as glass and/or plastic prism for instance. The light refracting element can be utilized in and/or with the viewing trocar to refract (i.e., bend) light passing into the trocar through the trocar's window. As a result, the angled endoscope's field of view can be substantially aligned with the field of view of the trocar's window, thus allowing the angled endoscope and viewing trocar to be used together to create ports in a patient, including initial ports of endoscopic surgical procedures.
