LAPAROSCOPIC DEVICE

摘要

The invention is a laparoscopic device comprising an internal light source located at the distal end of the handle section, a central core comprising an optical system, and a light guide in the form of a cylindrical tube that is slipped over the central core. The light guide is adapted to cause the light emitted by the internal light source to propagate through it by internal reflection until light exits the light guide at the distal end of the laparoscope.
