[Prior Art] Generally, as the insertion portion of an endoscope becomes longer, the overall weight of the insertion portion increases and the frictional force received during insertion also increases. In addition, the insertion section must have appropriate flexibility so that it can be inserted even if the object to be inspected is curved; however, with a long insertion section, the middle part of the insertion section tends to meander from side to side. Even if you push the part in, the tip will not move forward by the length of the push. In other words,
The longer the length of the insertion portion is, the worse the push followability becomes.

最近の工業用内視鏡のように有効長が4mを越える長さ

When the effective length exceeds 4 m, as in the case of recent industrial endoscopes, this inconvenience becomes noticeable.

[Problems to be Solved by the Invention] In order to improve such a decrease in followability, it is possible to select and use a material with a low coefficient of friction for the outer surface of the soft insertion part, or to reduce the overall contact area. In order to reduce the amount, it is possible to partially change the diameter smoothly.

However, neither of these methods significantly improves the meandering in the left and right direction that occurs when inserting the endoscope.
Even when the insertion part is pushed in, the tip of the insertion part has poor followability.

In addition, in particular, methods that change the outer diameter of the insertion tube reduce the effective diameter of the insertion tube, and new methods such as limiting the installation of image guides, light guides, channel members, etc. built into the insertion tube are required. A problem arises.

Therefore, even if the soft insertion portion meanders in the middle, the meandering disappears due to the transmission of the undulations and is returned to a straight state, making it easier for the pushing force to be transmitted to the distal end side. Moreover, the insertion resistance of the insertion portion can be reduced by the vibration. This improves the insertion performance of the endoscope.

When the endoscope 1 is used, the elongated insertion section 2 is pushed into the object to be examined, but the middle portion of the insertion section 2 gradually meanders. If the insertion length exceeds 4 m, for example,
The meandering becomes impossible to ignore, and because of this, the pushing force from the proximal side is not sufficiently transmitted to the distal end, and the phenomenon that it does not progress as expected becomes noticeable. Even if it is pushed in as it is, it will be absorbed by the meandering portion, and the meandering will only become larger, making it impossible to advance the tip portion 6 further.

Therefore, the fluid is intermittently injected from the injection port 12, but before this, the increase/decrease switches 14a and 14b are operated to adjust the injection pressure to the optimum level depending on the condition of the internal space of the object to be inspected. Then, the operation switch 15 of the operation unit 3 is operated to jet the fluid intermittently from the injection port 12. That is, as shown in Fig. 4, jet injection is performed at intermittent timing, and the portion of the insertion section 2 in the vicinity is intermittently levitated by receiving the thrust from this jet injection intermittently, and the process of ascent and landing is intermittently floated. A repetition of the action is performed. When such up and down movements are repeated, the undulations are sequentially transmitted from the distal end of the insertion section 2 to the proximal side, and this movement smooths out the meandering, resulting in a state in which it passes through an almost straight, shortest path within the insertion space. become. Therefore, the pushing force from the proximal side is transmitted to the tip side of the scraper blade without loss, and the insertion portion 2 can be inserted deeper. Furthermore, this undulation reduces the frictional resistance of the insertion portion 2, thereby reducing the insertion resistance.

If the condition of the internal space of the object to be inspected to be inserted is inappropriate for observation, for example, if it is extremely dry and has lumps or dust accumulated, operate the spray switch 18 to
As shown in the figure and FIG. 5, a cleaning liquid is sprayed from the spray nozzle 16 to clean the observation surface. In addition, if the observation window surface of the observation optical system becomes dirty, curve the curved portion 5 upward to face the direction of the spray, or position it in the falling direction of the spray as shown in FIG. Dirt can be washed away.

Therefore, in this second embodiment, the pressure increase/decrease switch 14
When the supply pressure is selected using the parameters a and 14b and the intermittent injection mode selection operation switch 15 is operated, pressurized fluid from the fluid supply source is intermittently supplied to the bottom space of the cylinder 32. Then, when the pressurized flow -10= body is supplied, the hammer 31 is pushed against the biasing force of the coil spring 34, slides, and strikes the striking portion 33.
In order to protrude, the tip 6 is struck on the ground surface on which it is placed, and the reaction lifts the tip 6. When the supply of fluid is stopped, the fluid continues to escape from the thin discharge hole 35 in the hammer 31, the hammer 31 returns to its original state due to the biasing force of the coil spring 34, and the striking portion 33 retracts from the side peripheral surface of the tip portion 6. . In this way, by intermittently supplying fluid to the cylinder 32, the hammer 31 is reciprocated and the striking part 33 is repeatedly pushed up and down. , repeat the ascent and landing motions. In this way, the vertical movement of the distal end 6 is controlled by the insertion part 2.
It becomes an undulating movement that is transmitted sequentially from the tip side to the hand side,
This movement smooths out the meandering and brings it into a state where it passes through a substantially straight, shortest path within the insertion space. Therefore, the pushing force from the proximal side is transmitted to the extreme blade tip side without loss, and the insertion portion 2 can be inserted deeper.

[Effects of the Invention] As explained above, according to the present invention, vertical movement is repeatedly applied to the distal end portion of the insertion portion to transmit undulations to the soft insertion portion. Even if the insertion part is meandering in the middle, the meandering disappears due to the transmission of this undulation, and it can be arranged in a straight state. At the same time, insertion resistance can be reduced and the pushing force of the insertion part can be reduced by the insertion force. It can be used efficiently for operation and improves the insertion performance of the endoscope. And this can be achieved by simply adding a simple structure.
