摘要

Detection and display device (1) for detecting and indicating the presence or absence of a stabilization bar (10) in the tulip head of a pedicle screw (9), characterized by a housing (2) adapted to be fitted with extended flanks of the pedicle screw (9) or a downtube (8) coupled to the pedicle screw, and a detection rod (3) axially displaceably mounted in the housing (2), whose relative positioning to the housing (2) indicates a detection result.
