In this case, the tension roller 66 or its latching element engages only in a latching position 68 when the withdrawal of the supply line 24 is stopped and a backward movement of the supply line 24 is initiated. The pull roller 66 thus does not run back in the upper gear 72 in an initial position, but moves to the nearest detent position 68. A renewed short train or a short further pulling out of the supply line 24 releases the pull roller 66 again, so that these 66 and . whose locking element in a lower gear 74 retrieved via the roller spring 64 and the supply line 24 is retracted to the starting position.
  • the pull roller 66 returns via a path 76 provided for this purpose into the upper gear 72 and can be moved over existing latching positions 68. In this case, the pull roller 66 or its latching element engages again in a latching position 68 when the withdrawal of the supply line 24 is stopped and a backward movement of the supply line 24 is initiated.
  • the base module 34 can be used universally by being designed such that it covers a plurality of supply connection variants 56 already present in the installation section of the treatment unit, so that the connections only from within the base module 34 from an existing supply connection 56 to the supply lines 24 of the articulated arm 12 are.
  • FIG. 10 shows a schematic representation of the course of a supply line in two different positions a) and b) of the instrument table 14.
  • the first joint 16 is formed such that the instrument table 14 relative to the deflection segment 18 horizontally and that on both sides from a central position to can be pivoted to 45 °.
  • Fig. 10 shows, on the one hand, the central position b) and on the other hand, the pivoted by 45 ° position a) of the instrument table.
  • Fig. 1 1 shows a schematic representation of two trays a) in the assembled state in plan view, b) in the assembled state in front view and c) in the detached state in end view.
  • the trays 36a, 36b are designed such that they can be connected to form a stable table top 36 with each other, preferably via a tongue and groove 58 - system.
  • the groove is not shown in the tray 36a.
  • a cover 62 is provided which covers a gap forming between two juxtaposed trays 36a, 36b, the cover 62 preferably being arranged on one of the trays 36a, 36b, for example as a projection.
