Abstract:
1. Surgical instrument, in particular a sliding shaft instrument, comprising: a main part and a relative moveable part, with a handle arranged on the main part, the former having a fixed grip and a grip for actuating the moveable part, with at least one guide through which the moveable part relative to the main part is moveable between an initial position and a working position, and the moveable part is guiding at the distal end with a hinge joint, the moveable part having a sliding surface pointing to the main part and also having a pair of side surfaces extending upwardly from the sliding surface from a proximal end of the sliding surface to a distal end of the sliding surface, the main part having a guide surface pointing to the sliding surface and also having a pair of side surfaces extending downwardly from the guide surface from a proximal end of the guide surface to a distal end of the guide surface, the sliding surface being slidable along the guide surface, whereby the sliding surface and the guide surface are arranged at least partially with each other for the formation of a washable gap, and that, by angling the side surfaces of at least one of the main part and the moveable part, at least the sliding surface or the guide surface is reduced transversely to the longitudinal direction of the moveable part and the main part to a width or at least the sliding surface or the guide surface is opened by at least one recess extending transversely from one of the side surfaces to the other of the side surfaces of at least one of the main part and moveable part, improving the formation of the gap between the sliding surface and the guide surface for the cleaning of the surgical instrument.
