Pocket-sized light source device (PLSD): An alternative light source for endoscopic surgery in urology

ABSTRACT

OBJECTIVE: Endoscopic surgery is one of the most common minimally invasive surgical techniques applied in the field of urology. The authors developed a mechanical adaptor for commercially available penlight-type LED light that can be used in common endoscopic procedures in urology. MATERIALS AND METHODS: A four-piece light adaptor device made from medical-grade aluminum steel was crafted and functions as an adaptor for penlight-type LED light in one end and an endoscopic telescope on the other end. In order to determine its function and quality, it was compared to the conventional light source machine used in most endoscopic procedures. The specification of both light sources were compared in terms of light intensity and colour temperature through a light meter. This device was applied clinically by using it in a series of endoscopic procedures. RESULTS: Application of the device in the endoscopic surgical procedures showed that it functioned well and appropriately. It was able to complete a full course of each operation undertaken. CONCLUSION: This original an innovative device offers an alternative to the conventional light source equipment available commercially. Based on the authors experience we recommend the use of this adaptor for common endoscopic procedures done in minimally invasive surgery.
