ABSTRACT
INTRODUCTION: The purpose of this paper is to present the development and design of an abdominal retractor which allows a single person to perform operations and the fixation of the operation instruments can be done with one hand. The additional devices make the operation more comfortable for surgeons. METHODS: Conventional measuring devices have been designed and applied for determining axial forces in a surgeon's forearm during operations. The same forces must be transmitted by the frame of the retractor. Thus a simple truss structure of a retractor was done. Several types of fixations have been proposed and tested using the rapid prototyping. Finally, the abdominal retractor was manufactured from stainless steel. RESULTS: The simple-to-use abdominal retractor was built. The standard surgery instruments were modified due to the fixation system of the frame. A wide variety of additional useful devices, such as a lamp, video camera etc., were also proposed. CONCLUSION: The present abdominal retractor is user-friendly and all components are easily sterilized by conventional methods (Fig. 7, Ref. 6) Keywords: abdominal retractor, stainless steel retractor, standard surger, fixation system of the frame, lamp, video camera, conventional methods.
