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.
In order to realize the simulation testing and calibration of star tracker in the lab, a simulation algorithm for dynamic and celestial sphere star image was proposed. This algorithm could complete simulation of star image at any time and any visual axis point, also could realize in-orbit simulation according to a given track. A new method of space district dividing was also presented in order to improve the traditional method of space district dividing by ascension and declination, fully considered declination arc length gradually shortened with latitude increasing. It can remarkably enhance the updating frequency simulation star image.
