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

Abstract

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.

Design of Double-Light Shadowless Lifting Retractor

“…For the tests did in this paper, the low luminosity test is the same to Ref. [2], and the high luminosity test is as follows.…”

“…The shadowless cold light lifting retractor, which is composed of one distraction device and two 'L' shaped retractor, is an important component of the SPGLSI. Through continuous improvement, the shadowless cold light lifting retractor has been developed as the three-light high luminosity cold light lifting retractor [2] [3] . The 'L' shaped three-light high luminosity cold light lifting retractor is shown in Fig.…”

“…Then, the surgeon puts two 'L' shaped retractors into it back to back, fixes them with the distraction device, and then pulls the open device with the wire rope. The distraction device will drag the 'L' shaped retractor and make the celiac lift, so as to realize lighting [2]. Just like the hanger principles, it is impossible to hang the clothes if the rack is inserted flatly into the clothes, the hanger should be cut into two parts along the direction of the hook, then be inserted flatly and be fixed on a hook, which can lift clothes at last.…”
