Surgical sliding shaft instrument and sliding shaft

摘要

In order to improve a sliding shaft for a surgical sliding shaft instrument, wherein the sliding shaft defines a longitudinal direction and comprises a first shaft part and a second shaft part which are arranged such that they are displaceable relative to each other, wherein said first shaft part carries a first tool element and said second shaft part carries a second tool element, wherein the second shaft part has a cut material collector with an inlet opening which is bounded by the second tool part and extends therefrom in the proximal direction, such that the cut material collector can be emptied in a simple and rapid manner, it is proposed that the cut material collector should have at least one emptying opening which is formed on the proximal side of the inlet opening and that the at least one emptying opening should be open in a lateral emptying direction which is oriented perpendicularly or substantially perpendicularly with respect to the longitudinal direction and parallel or substantially parallel to a contact plane defined by a lower surface of the second shaft part.

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.
