Objects sometimes get damaged by anatomical forceps or slip out of their grip. Therefore, a forceps based on the Fish fins effect was developed. This effect was discovered 20 years ago when fishing and was used in biomimetic robot grippers from Festo. The jaws of the forceps adapt to the shape of the object that is handled with it while standard anatomical forceps force objects to adapt to their shape. Due to this unique property, less and more uniform pressure is applied on the object. Furthermore, it is possible to apply targeted pressure on objects by using the tips of the Fish fins effect -forceps. This offers the usual properties that users expect from forceps. Soft tissues can be handled with these forceps as well. This biomimetic instrument was chosen In the Devicemed magazine, in the "Research" section, foreceps were ranked second among the best developments in Medical technology selected in 2018.
