초록
Developing new surgical instruments is challenging. While making surgical instruments could be a good field of application for3D printers, attempts to do so have proven limited. We designed a new endoscope-assisted spine surgery system, and using a 3Dprinter, attempted to create a complex surgical instrument and to evaluate the feasibility thereof. Developing the new surgical instrumentsusing a 3D printer consisted of two parts: one part was the creation of a prototype instrument, and the other was the productionof a patient model. We designed a new endoscope-assisted spine surgery system with a cannula for the endoscope andworking instruments and extra cannula that could be easily added. Using custom-made patient-specific 3D models, we conducteddiscectomies for paramedian and foraminal discs with both the newly designed spine surgery system and conventional tubularsurgery. The new spine surgery system had an extra portal that can be well bonded in by a magnetic connector and greatly expandedthe range of access for instruments without unnecessary bone destruction. In foraminal discectomy, the newly designed spinesurgery system showed less facet resection, compared to conventional surgery. We were able to develop and demonstrate the usefulnessof a new endoscope-assisted spine surgery system relying on 3D printing technology. Using the extra portal, the usabilityof endoscope-assisted surgery could be greatly increased. We suggest that 3D printing technology can be very useful for the realizationand evaluation of complex surgical instrument systems.
