Abstract

An endoscopic instrument is disclosed that includes an elongate shaft and an instrument insert releasably connected to a distal end portion of the shaft, the distal end portion of the shaft being in the form of a sleeve and a proximal end region of a base of the instrument insert being in the form of a coupling shaft, or the distal end portion of the shaft being in the form of a coupling shaft and a proximal end region of a base of the instrument insert being in the form of a sleeve, with the coupling shaft being releasably held in the sleeve and the sleeve and/or the coupling shaft at least in portions having a cross-sectional profile which is reversibly changeable for detaching the coupling shaft from the sleeve. The invention also relates to a shaft for an endoscopic instrument, and to an instrument insert for an endoscopic instrument.
