The working principle of the utility model is as follows:

all advancing end sections 11 have different sizes in friction force, and by utilizing the difference, the similar creeping and piling type advancing mode can be realized, and the damage to the intestinal tract is avoided.

Specifically, the three advancing end sections 11 are sequentially sequenced in the direction from the head end to the tail end, the advancing end section 11 at the head end is a first advancing end section, and the second advancing end section and the third advancing end section are sequentially arranged behind the first advancing end section. Similarly, the advancing guide pillars 12 are also named as a first advancing guide pillar, a second advancing guide pillar and a third advancing guide pillar in sequence; the advancing mechanism 1 is named as a first advancing mechanism, a second advancing mechanism and a third advancing mechanism in sequence.

The initial state of forward travel of the colonoscope is shown in the first row of the structure in fig. 2. First, the first advancing end section is electrified and advances from the tail end to the head end of the first advancing guide post, all the advancing end sections 11 are in direct contact with the intestinal tract, friction force exists between the first advancing end section and the first advancing end section, the friction force is reaction force, the force output of the first advancing end section is not enough to drive the whole colonoscope to advance, the first advancing mechanism is wholly in a contraction state, and the first advancing mechanism is powered off.

It should be noted that the retracted state, i.e., the advancing end section 11 is located at the advancing end of the advancing guide post 12 and remains unchanged.

And then, the second advancing end section is electrified and advances from the tail end to the head end of the second advancing guide post, the force of the second advancing mechanism is insufficient to drive the whole colonoscope to advance, the second advancing mechanism also enters a contraction state, and the second advancing mechanism is powered off.

Then, the third advancing end section is electrified, the third advancing end section advances from the tail end to the head end of the third advancing guide pillar, the force of the third advancing mechanism cannot drive the whole colonoscope to advance, the third advancing mechanism also enters a contraction state, and the third advancing mechanism is powered off.

The three advancing mechanisms 1 are all in a contracted state, the colonoscope as a whole enters a structural state of the second row in fig. 2, at the same time, the three advancing end joints 11 are electrified in a same time, and the control signals are reversed, as shown in the structure of the third row in fig. 2, namely, the three advancing end joints 11 are controlled to advance towards the tail ends of the corresponding advancing guide posts 12 in a same time, the colonoscope is reset to the initial state, but the colonoscope as a whole advances for a certain distance, and the advancing mechanisms 1 are powered off.

At the moment, the sum of the forces of the three advancing mechanisms 1 is not enough to directly drive the colonoscope to move forwards, but the reaction force of the forces can drive the lens mechanism 2, the advancing guide pillar 12, the universal joint 13 and the structure of the protective end joint 3 to move forwards together.

It can be understood that the three advancing end joints 11 form supporting points with the inner wall of the intestinal tract, the force exerted by the three advancing mechanisms 1 cannot directly drive the colonoscope to advance directly, and only one advancing mechanism can move independently, and then the structures related to the advancing mechanism are driven to move relatively by the reaction force together, so that the peristaltic advancing of the colonoscope is indirectly realized.

It should be noted that the structure of the colonoscope cannot realize the direct travel of the three travel mechanisms 1, and the direct travel mode is extremely harmful to the intestinal tract.

Similarly, when the direction is reversed, the control signals of the corresponding steps are reversed or the current direction is changed, so that the whole colonoscope can move reversely, and the retraction function of the colonoscope is realized.

The traction efficiency of the colonoscope is related to the length of the advancing guide posts 12 or the number of the advancing mechanisms 1, and the influence of mucus in the intestinal tract on advancing is also considered, so that the traction efficiency can be selected and set correspondingly. The three travel mechanisms 1 are shown here by way of example for reference and are not intended to be a fixed limitation.

When the user operates the operation terminal 61, a control command is sent to the receiving terminal 62. The receiving end 62 amplifies or converts the control command into an operation command, and then sends the operation command to the processing end 63. The processing terminal 63 transmits signals to specific components, such as the driving unit 43, the traveling end section 11, and the like, to perform specific operations.

When the colonoscope reaches a designated position or a proper position, the driving assembly 43 is started to drive the sliding member 42 to move along the sliding column 41, the sliding member 42 drives the air bag member 44 to extend out of the air bag groove and tilt outwards under the action of the protrusion 45, and the actual contact point of the lens mechanism 2 and the intestinal tract is the end point of the air bag member 44 and is clamped with the intestinal tract, so that the lens mechanism 2 is further fixed. The visual angle is fixed, and the observation is convenient.

After the observation is finished, the air bag piece 44 is driven by the driving component 43 to retract into the air bag groove, and the actual contact point of the lens mechanism 2 and the intestinal tract becomes the outer wall of the lens barrel shell 21, so that the moving action can be started.

It will be apparent to those skilled in the art that various modifications may be made to the above embodiments without departing from the general spirit and concept of the utility model. All falling within the scope of protection of the present invention. The protection scheme of the utility model is subject to the appended claims.
