Study and Design of a 3-Lamp Cold Light Lifting Retractor

This paper introduces the composition and usage of the18 luminescence tubes shadowless retractor, the Single-port gasless laparoscopy minimally invasive surgical instrument， which is the national patent products. As for the issue of inadequate illuminating intensity, the 3- lamp cold light Lifting retractor system is presented for the first time in domestic, as well as its designing and manufacturing procedure. It also presents the trial-producing of 3- lamp cold light Lifting retractor and its supporting power box. The system has been tested. It can apply to the disaster relief field and other special conditions, at the same time, it can improve the intensity of illumination with its simple producing procedure.
