====== Endoscope-assisted spine surgery system ======

Developing new surgical [[instruments]] is challenging. While making [[surgical instrument]]s could be a good field of application for [[3D printer]]s, attempts to do so have proven limited. 

Yang et al. designed a new [[endoscope]]-assisted [[spine surgery]] system, and using a 3D printer, attempted to create a complex surgical instrument and to evaluate the feasibility thereof. Developing the new surgical instruments using a 3D printer consisted of two parts: one part was the creation of a prototype instrument, and the other was the production of a patient model. 

They designed a new endoscope-assisted spine surgery system with a [[cannula]] for the endoscope and working instruments and extra cannula that could be easily added. Using custom-made patient-specific 3D models, they conducted discectomies for paramedian and foraminal discs with both the newly designed spine surgery system and conventional [[tubular]] surgery. The new spine surgery system had an extra portal that can be well bonded in by a magnetic connector and greatly expanded the range of access for instruments without unnecessary bone destruction. In a foraminal discectomy, the newly designed spine surgery system showed less [[facet]] resection, compared to conventional surgery. 

They were able to develop and demonstrate the usefulness of a new [[endoscope-assisted spine surgery system]] relying on 3D printing technology. Using the extra portal, the usability of endoscope-assisted surgery could be greatly increased. They suggested that 3D printing technology can be very useful for the realization and evaluation of complex surgical instrument systems
