During a vitrectomy procedure vitreous is removed from the eye with a vitreous cutter, called a vitrectome. This instrument is comprised of two needles that move to cut the vitreous into small pieces before aspirating them. Vitreous cutters are complex instruments that are light and small in size to increase their accuracy. Because of their...

The DragonFlex, world’s first 3D-printed steerable Minimally Invasive Surgery (MIS) instrument, showing promising results for the medical field, is made by means of 3D-printing, and features simple assembly, while exhibiting high bending stiffness. In this research, the possibilities with additive manufacturing are explored even further, by...

Engineers typically design heavy and powerful tools for the use of bulk transfer. High forces are needed to penetrate and to propagate into the bulk. Especially when using a grab, a reduction of mass is desirable. In the conventional approach an optimization problem is encountered as a further reduction in mass reduces the grabs ability to...

Flexible steerable needles can follow curved paths inside the human body, allowing to steer around objects, to adjust for mispunctures, and to reach multiple targets. However, the designs of existing ultra-thin (diameter < 1 mm) steerable needles require axial rotation of the needle to steer in 3D space causing needle twisting, which results...

Current endoscopic devices cause great discomfort to the patient because they need to be pushed from outside the patient to manoeuvre through the intestine. Self-propelling endo- scopic concepts have been proposed, but these cause unnecessary trauma to the patient or are unable to travel to the end of the large intestine and back. This study...
