Its applications have expanded considerably over the last 20 years and have found use in various fields. This study is our initial attempt to investigate the feasibility, design and fabrication process of a usable 3D printed ring retractor system. METHODS Using a low cost, desktop, fused deposition manufacturing (FDM) printer, Turner Warwick surgical retractor system was replicated from polylactic acid (PLA) filament. The retractor was sterilized using glutaraldehyde, and tested in-vitro for strength. The final printed products were evaluated by practicing urologists for ergonomic functionality and performance. RESULTS The design process was completed in 3 days and the printing required roughly 6 hours. Initially printed instruments were found to give way at the hook of the blades. After appropriate modification the instruments were re-printed. All the five urologists found no inferiority in the functionality and performance of this retractor system compared to commercial stainless steel instrument. CONCLUSIONS We found the process of in-situ making of functional 3D printed surgical instruments easy and feasible. Advantages include reduced cost, fast-tracked design to production times and surgeon specific modifications. The 3D printed retractor is strong enough for the demands of the operating room. Due to the unprecedented accessibility of 3D printing technology worldwide, and the cost efficiency of these instruments, there are far reaching implications for surgery in some underserved and less developed parts of the world. © 2018FiguresReferencesRelatedDetails Volume 199Issue 4SApril 2018Page: e805-e806 Advertisement Copyright & Permissions© 2018MetricsAuthor Information Manav Agarwal More articles by this author Bhupendra Pal Singh More articles by this author Vikas Kumar More articles by this author Apul Goel More articles by this author Satya Narayan Sankhwar More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
