Abstract
A medical instrument, particularly an endoscope, is provided with a device to guide the instrument within the intestine. The device is forwardly movable stepwise within the intestine with intermittent contact with the intestine wall. The device is so constructed to enable one to first push together on the instrument a part of the intestine surrounding the instrument, and then the device can be quickly pushed forward by taking advantage of the intestine's own inertia.
