摘要： An instrument for guiding a rod into a holder of an implant, in particular a pedicle screw, includes a coupling unit for coupling the instrument to the implant, in particular a head of the pedicle screw, a threaded rod that can be positioned in the axial direction relative to the coupling unit, and at least one internally threaded segment that is arranged in an axially fixed manner relative to the coupling unit, and can be positioned in a radial direction relative to the threaded rod, and prestressed toward the threaded rod by a prestressing element applying a radial force. The internally threaded segment can be brought into engagement with, and disengaged from, the male thread of the threaded rod by radial positioning. Thread flanks of the threaded rod and thread flanks of the internally threaded segment face each other and are each formed with an undercut.

摘要： A surgical instrument for manipulating and positioning a surgical rod relative to a surgical implant features two legs rotatably coupled to each other by a hinge. Each leg includes a working end. The working ends come into engagement with the implant upon closing the instrument by rotating the legs around the hinge and pivotally position the instrument relative to the implant around a swivel axis transverse to its longitudinal axis. At least one of the legs includes a contact structure for a surgical rod by which the rod is manipulated and positioned upon swiveling the instrument around the swivel axis relative to a rod seating of the implant. At least one of the legs includes a guide structure for guiding a fixation screw, to be screwed in, for the rod and/or for a tool for screwing in the fixation screw after having positioned the rod in the rod seating.

摘要： An instrument for guiding a rod into a receiving area of an implant includes a coupling unit for coupling the instrument to the implant, a rod provided with an outer thread that can be positioned axially relative to the coupling unit, and at least one inner threaded segment arranged in an axially fixed manner relative to the coupling unit that can be brought into engagement or out of engagement with the outer thread of the threaded rod. The threaded rod has a stop, and the instrument has a locking element which is arranged in an axially fixed manner relative to the coupling unit for interacting with the stop. The locking element can be positioned in a radial direction relative to the threaded rod and is pretensioned in the direction of the threaded rod to engage with the stop by a pretensioning element which applies a radial force.

摘要： A detection and indication device for the detection and indication of the presence or absence of a stabilization bar in the tulip head of a pedicle screw includes a housing. The housing is adjusted in such a way that it can be connected with elongated flanks of the pedicle screw or a downtube coupled to the pedicle screw in a detachable manner. A detection bar can be mounted axially movable in the housing. The relative positioning of the detection bar to the housing indicates a detection result. A system for spinal stabilization includes at least one pedicle screw with a tulip head and elongated flanks or a downtube coupled to the pedicle screw, at least one stabilization bar and a detection and display device.
