Abstract
A shaft of a laparoscopic instrument, having a ceramic tube which extends over the main length of the shaft and has a sheath which encloses the ceramic tube in at least some regions, is situated to cover those regions of the ceramic tube that are at risk of breakage and is designed to prevent the splinters of ceramic from penetrating through the sheath. The ceramic tube forms a predetermined breaking point in the region of the sheath.
