In this study, we tested the function of a replica of the over 500-year-old original of the
famous Franconian Imperial Knight Götz von Berlichingen’s first “iron hand”, which we
reconstructed by computer-aided design (CAD) and recently printed using a multi-material
3D printer. In different everyday tasks, the artificial hand prosthesis proved to be remarkably
helpful. Thus, the hand could hold a wine glass, some grapes, or a smartphone. With a
suitable pencil, even writing was possible without any problem. Although for all these
functions the healthy other hand was necessary to assist at the beginning, the artificial hand
is an astonishing mechanical aid with many possibilities. Therefore, in certain cases, the
non-invasive approach of a passive mechanical hand replacement, which is an individual,
quick and cheap solution due to modern 3D printing, may always be worth considering
also for today’s requirements.
Serendipities in der Medizin
(2016)
Zufälle begleiten unser Leben. Auch bei wichtigen Entdeckungen und Entwicklungen in der Medizin spielt der „Zufall“ (engl. „serendipity“) eine Rolle. Hierzu gehören u. a. die Mendelschen Gesetze, die Ermittlung der menschlichen Chromosomenzahl, die Entdeckung der DNS durch Watson und Crick, der PAP-Test oder die Entdeckung der Röntgenstrahlung und der Radioaktivität. Aber auch und gerade in der Pharmakologie gibt es viele Beispiele für Serendipitäten. Einige gehen eng mit Zufällen bei der Entdeckung der Bakteriologie einher.
