Abstract

The invention relates to a support (1) for receiving at least one surgical object, in particular at least one bone screw (2), in a receiving position (A). Said support (1) comprises at least one supporting surface (3) which is designed and arranged in such a manner that a supporting area (5) of the object can be brought into contact with the supporting surface (3) in the receiving position (A). Said object can be removed from the receiving position (A) in the direction of removal (E). The direction of removal (E) extends at an angle of a maximum 45°, preferably a maximum 20°, more particularly essentially parallel to a longitudinal axis (L) of the object housed in the receiving position (A). Said support (1) comprises at least one mounting surface (4) that can be moved in relation to the base body (23) and which is designed and arranged in such a manner that the object can be maintained by means of the mounting surface (4) in the receiving position (A), in particular in a clamped manner. The invention also relates to a mounting (26) for fixing a bone plate support (27) for a bone plate (28) to a base plate (29), a bone plate support (27) and a system comprising a mounting (26) and a unit (33) from a bone plate support (27) and a bone plate (28).
