Abstract: The present invention relates to plastic molded bodies having two-dimensional or three-dimensional image structures produced in the interior through laser subsurface engraving. The plastic molded bodies are made of plastic materials which have a content of nanoscale metal oxides having particle sizes from 1 to 500 nm, both the plastic material and also the included metal oxide being transparent to the laser light used for producing the image structures. The plastic materials from which the molded bodies are manufactured particularly contain metal oxides having particle sizes from 5 to 100 nm at a content of 0.0001 to 0.1 weight-percent. Typical metal oxides are nanoscale indium-tin oxide or antimony-tin oxide.

Abstract: The invention relates to a medical instrument (1) for sectioning, removing, and particularly modeling bones, cartilage, and the like, in particular for a nasal bridge osteotomy, said instrument including a chisel (2) with a shaft (2a) and a chisel blade (2b) installed on the distal end of the shaft. A medical instrument (1) that allows easy and precise guidance of the chisel (2) is characterized, in accordance with the invention, by a handle (3) on which the chisel (2) can be secured for holding and guiding.
