Latest Patents

Grell holds a patent for a "Procedure and apparatus for screwing implants into bones." This invention features an artificial hinge pin with a self-cutting threaded portion, which is inserted into a prepared bone using a hand-held power tool. The tool imposes a rotary oscillating movement on the pin during the insertion process, enhancing efficiency and reducing the reaction moment. The design includes an output shaft driven by an overriding ratchet-type coupling that provides repeated impacts to the output shaft. Additionally, a plurality of elastic rods connected to the output shaft are arranged coaxially around the shaft and anchored to a rotary brake disk, with braking force controlled by an adjustable compression spring. The eigenfrequency of the elastic system can be adjusted to match the impact frequency of the ratchet coupling.
