Abstract
The endoscopic instrument for introducing elongate medical assisting devices into the body of a patient comprises an elongate shank which is provided at its proximal end with a handle for the instrument, whereby the shank comprises at least one recess for receiving and guiding an elongate assisting device, said recess beginning distally and extending at least partly along said shank's length. For improving the introduction of the assisting device into the body of the patient the shank is surrounded by a hollow outer shank which comprises at least one longitudinal slit extending from its distal end along at least a part length of the outer shank, whereby the outer shank is twistable or distally displaceable over the inner shank for overlapping the recess of said inner shank, and can be positioned in the overlapping position.
