The specific operation principle of realizing the self-expansion function of the front end part of the enteroscope is as follows: the elastic part between the first walking body and the second walking body is compressed, when the first walking body and the second walking body approach each other, the first air bag is deflated, the second air bag is inflated, the inflated second air bag fills the whole intestinal canal and becomes a fulcrum, the first air bag is deflated and flat, at the moment, the sliding block of the hand-held mechanism is controlled to slide downwards, the elastic part is loosened, the elastic part restores the elastic shape under the action of the self elastic force, the second air bag and the intestinal canal keep relatively static, the effect of forward propulsion of the first walking body under the action of the elastic part is realized, at the moment, the distance between the first walking body and the second walking body is increased, the hand-held part is pushed to move forwards by inflating the first air bag and deflating the second air bag, because the first air bag is inflated and the intestinal canal keep relatively static, the elastic part between the first walking body and the second walking body is compressed, the first walking body and the second walking body approach each other, the above steps are repeated, and the two air bags move forwards in one step by the cooperation of the elastic parts, make first gasbag realized autonomous movement under the effect of not depending on the external force, utilize first gasbag to advance under the elasticity promotion of elastic component, cooperate handheld mechanism to the propulsion of second gasbag and to the compression of the distance between the two simultaneously, realize walking in the intestines tube by oneself, replace operating personnel to promote inner tube and outer tube in human outside in turn.

The enteroscope can be used in the following specific way:

step 1: the enteroscope is placed in the small intestine, when the camera detects that the first walking body does not advance forwards any more in the pushing state, at the moment, a doctor pulls the slide block upwards through the hand-held piece, the elastic piece between the first walking body and the second walking body is compressed by the connecting piece, and the first walking body and the second walking body are in a close state; at the moment, the first air bag and the second air bag are in an uninflated state;

step 2: the second air bag is inflated, the inflated second air bag is clamped at the position of the intestinal canal and keeps relatively static with the intestinal canal, at the moment, the sliding block of the handheld mechanism is controlled to slide downwards, the connecting piece between the first walking body and the second walking body stretches, the elastic piece recovers the elastic shape under the action of the elastic force of the elastic piece, and the first walking body is pushed forwards under the condition that the second air bag and the intestinal canal keep relatively static;

and step 3: the first air bag is inflated and the second air bag is deflated, the inflated first air bag is clamped at the position of the intestinal canal and keeps relatively static with the intestinal canal, at the moment, the handheld mechanism is pushed to push the second walking body to advance, and meanwhile, the sliding block is lifted upwards, so that the elastic piece between the first walking body and the second walking body is compressed;

and 4, step 4: sequentially repeating the step 2 and the step 3;

and 5: and after the detection is finished, the first air bag and the second air bag are deflated and then taken out from the intestinal tract.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
