Abstract:
1. A sliding shaft for a surgical sliding shaft instrument which defines a longitudinal direction and comprises: a first shaft part and a second shaft part which are arranged such as to be displaceable relative to each other, said first shaft part carrying a first tool element and said second shaft part carrying a second tool element, the second shaft part comprising a cut material collector having an inlet opening which is completely bounded by a cutting edge of the second tool element, the cut material collector extending from the inlet opening in a proximal direction, the cut material collector comprising at least one emptying opening which is formed on a proximal side of the inlet opening, the at least one emptying opening being open in a lateral emptying direction, which emptying direction is oriented perpendicularly or substantially perpendicularly to the longitudinal direction and parallel or substantially parallel to a contact plane defined by a lower surface of the second shaft part, wherein an internal cross sectional area of the cut material collector continuously increases from a distal end of the cutting edge of the second tool element in the proximal direction.
