In this context, the presented 3D-printed Single-Port Overtube Manipulator System follows the aims to provide patient- and task-specific disposable manipulators for minimally invasive surgery. In a first experiment, the robustness of the monolithic flexure hinge structures in use as robotic manipulators will be investigated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Customizable monolithic manipulator structures designed by means of an automated design process and manufactured with selective laser sintering were investigated with regard to long-term stability in an endurance test. Therefore, a bare manipulator arm, an arm equipped with a standard instrument and finally loaded with an additional load of 0.5\u00a0N were evaluated by continuously following a trajectory within the workspace of the manipulator arms over a period of 90\u00a0min.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The unloaded manipulator as well as the manipulator arm equipped with a standard instrument showed a sufficient reproducibility (deviation of 1.5\u00a0mm and 2.5\u00a0mm, respectively, on average) with regard to an application as telemanipulated master\u2013slave surgical robotic system. The 3D-printed manipulators showed no damage and maintained integrity after the experiment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>It has been shown that 3D-printed manipulators in principle are suitable for use as disposable surgical manipulator systems and offer a long-term stability over at least 90\u00a0min. The developed manipulator design shows great potential for the production of patient-, task- and user-specific robot systems. However, the manipulator geometries as well as the control strategies still show room for improvements.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s11548-020-02244-6","type":"journal-article","created":{"date-parts":[[2020,8,13]],"date-time":"2020-08-13T10:04:12Z","timestamp":1597313052000},"page":"1693-1697","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Evaluation of long-term stability of monolithic 3D-printed robotic manipulator structures for minimally invasive surgery"],"prefix":"10.1007","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1670-3654","authenticated-orcid":false,"given":"Yannick S.","family":"Krieger","sequence":"first","affiliation":[]},{"given":"Daniel","family":"Ostler","sequence":"additional","affiliation":[]},{"given":"Korbinian","family":"Rzepka","sequence":"additional","affiliation":[]},{"given":"Alexander","family":"Meining","sequence":"additional","affiliation":[]},{"given":"Hubertus","family":"Feussner","sequence":"additional","affiliation":[]},{"given":"Dirk","family":"Wilhelm","sequence":"additional","affiliation":[]},{"given":"Tim C.","family":"Lueth","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2020,8,13]]},"reference":[{"key":"2244_CR1","doi-asserted-by":"publisher","first-page":"168","DOI":"10.1016\/j.csbj.2017.01.004","volume":"15","author":"N Kurniawan","year":"2017","unstructured":"Kurniawan N, Keuchel M (2017) Flexible gastro-intestinal endoscopy\u2014clinical challenges and technical achievements.
