Abstract Standard laparoscopes, which are widely used in minimally invasive surgery, have significant handling limitations due to their rigid design. This paper presents an approach for a bending section for laparoscopes based on a standard semi-fini

The mechanics of medical endoscopes have not fundamentally changed over the last 40 years. Most endoscopes are manually operated through Bowden cables to control the head of the device, which is known to have major limitations. We propose a shape mem

Mechanical Design of Intersection Points of Tailored Fiber Placement Made Carbon Fiber Reinforced Plastic Truss-Like Structures

Autor: Lars Bittrich, Kai Uhlig, Gert Heinrich, Emanuel Richter, Axel Spickenheuer

Publikováno v: Key Engineering Materials. 809:452-460

The presented study emphasizes a favored design for carbon fiber reinforced plastic fiber patterns at intersection points of truss-like structures made with the Tailored Fiber Placement technology. Three different pattern types have been experimental

Under normal conditions, the cross-sections of reinforced concrete in classic skeleton construction systems are often only partially loaded. This contributes to non-sustainable construction solutions due to an excess of material use. Novel cross-disc
