Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an endoscope of an endoscope cover type, and more particularly to an endoscope of a channel type endoscope cover type.

[0002]

[Prior art]

 For endoscopy, it is necessary to use a clean endoscope that has been thoroughly washed and disinfected before the examination. Therefore, when the endoscope used for an examination is used for the next examination, the next examination cannot be started during the time necessary to sufficiently perform such cleaning and disinfection, and it is necessary for the treatment. Takes time and effort.

In order to reduce these inconveniences, such a conventional reusable endoscope is replaced with an insertion part that has been washed and disinfected in advance and an insertion part after inspection (that is, after use). A disposable endoscope cover type endoscope has been proposed. According to this, compared with conventional endoscopes of repeated use type, that is, endoscopes without a cover, the time required for cleaning and disinfecting each time required conventionally as described above is reduced and the workability is improved. Can be expected. Such an endoscope with an endoscope cover system is composed of a combination of an endoscope cover and an endoscope for an endoscope cover to be inserted into the endoscope cover.

[Problems to be solved by the device]

 The following points can be pointed out in the technology regarding the endoscope of the endoscope cover type according to the conventional proposal.

In the case of an endoscope cover with a channel, the endoscope cover with a channel has air supply, water supply, suction channels, etc., and the endoscope cover with a channel is also included in advance including the various tubes. It is recommended to prepare it in a sterilized state. On the other hand, when in use, the various tubes are connected to the air, water, and suction control devices, but during the process of reaching the device, the various tubes are removed from the insertion section cover of the endoscope cover with channels. If it extends to the side of the fluid control device in a slumped state, such tubes that are stretched like "Daraan" will hang around the operation part of the endoscope in a cluttered state, which is not preferable for handling. If a sterilized operating unit cover or universal cord cover is also used to prevent contamination, the presence of the tubes will hinder the attachment of the cover and the workability of attaching the cover, etc. Becomes worse. Also, if the tubes are dangling, they may come into contact with contaminated parts such as unclean floors, and the outer or inner surface of each sterilized cover should be protected from such tubes. There is also the risk of contamination with other species. Furthermore, even if the tubes are covered together, if the tubes are not fixed at all, moving the operation part during inspection will cause the tubes to move within the cover, which is very annoying. . In the conventional proposals, measures from such a point are not considered.

Therefore, an object of the present invention is to provide an endoscope with a channel which is excellent in handleability and which can appropriately prevent the covers from being contaminated through the conduit tube from the endoscope with a channel. An object is to provide a cover-type endoscope.

[0007]

In the present embodiment, the tubes of the respective conduits protruding to the end of the endoscope operation section fixing mouth section 23 of the insertion section cover section 11 are covered by the tubes through the tubes. It is locked so that there is no risk of contamination. FIG. 5 is an explanatory view of the cover endoscope 7 portion of FIG. 1 including an example of a configuration for such locking. As shown in FIG. 5, the insertion portion 18, the operation portion 155, the universal cord portion 232, and the connector portion 164 of the cover endoscope 7 are respectively sterilized, and the insertion portion cover portion 11 and the operation portion cover of the cover 10 are sterilized. 12, covered with universal cord cover 13. The hand side tubes 238 consisting of the hand side suction tube 73, the hand side air supply tube 75, and the hand side water supply tube 74 protruding from the insertion section cover part 11 are the operation part 155, the universal cord part 232, the connector part in this example. Each of the locking members 234 provided at 164 is locked on the way, and each end is connected to the fluid control device 4 as shown in FIG.

6 to 14 show specific examples of the above-mentioned locking means, respectively. For example, in the case of FIG. 6, a locking member (A) 239 having a snap-fit structure is provided as the locking member 234 on the surface of the cover endoscope 7. The hand side suction tube 73, the hand side air supply tube 75, and the hand side water supply tube 74 can be stably and surely locked to the cover endoscope 7 by the locking members (A) 239.

Since the tubes 238 can be properly locked and regulated in this manner, for example, the sterilized operation unit does not hang around in the vicinity of the operation unit 155. The workability when attaching the cover 12 or the universal cord cover 13 is improved, and the tubes 238 do not move around and touch a contaminated portion such as the floor during attachment or inspection. As a result, it is possible to avoid the risk of contaminating the outer surface and the inner surface of the covers with the tubes 73 to 75, which would be contaminated if they come into contact with the floor or the like. Further, even if the operation unit 155 is moved during the inspection, the locked tubes 238 may move in a way that is troublesome for the operation such as when the operation unit 155 is not fixed to the operation unit. It is also less useful, and therefore more useful.

In the example of FIG. 7, a magic tape 240 is used as the locking member 234. In the example of FIG. 8, the magnet 241 and the metal ring 242 are used as the locking member 234. Here, the magnet 241 is fixed to the surface of the cover endoscope 7, while various tubes are passed through the metal ring 242, and the metal ring 242 is magnetized by the magnetic force of the magnet 241. It is adsorbed and locked and fixed. In the case of FIG. 9, the locking member 234 is a string 243. One end of the string 243 is fixed to the surface of the cover endoscope 7. With this string 243, various tubes can be locked and fixed.

Further, in the case of FIG. 10, as the locking member 234, a locking member (B) 244 having a concave shape in which each of the tubes 73 to 75 is fitted is provided, and as shown in the drawing. It is fitted and locked in the corresponding concave portions. In the example of FIG. 11, the locking member 234 is composed of a rubber ring 245 and a rubber ring support member 246. The rubber ring support member 246 is fixed to the surface of the cover endoscope 7. In this case, various tubes can be locked by hooking the rubber ring 245 on the support member 246 as shown in the figure. In the example of FIG. 12, the SK band 247 is used as the locking member 234.

Further, in the case of FIG. 13, the locking member 234 is composed of a suction cup 248 and a ring-shaped member 249 having at least one flat surface. The base side of the suction cup 248 is fixed to the surface of the cover endoscope 7. On the other hand, various tubes pass through the inside of the ring-shaped member 249. In this configuration, the flat surface of the ring-shaped member 249 is attracted to the suction cup 248 and locked. In the example of FIG. 14, the locking member 234 is an adhesive tape 250. Here, the adhesive tape 250 includes a covering material 251 and an adhesive material 252, and one surface of the adhesive tape 250 is fixed to the surface of the cover endoscope 7. In the locking method in this example, the covering material 251 is peeled off, and various tubes are attached to the adhesive material 252 and locked. Note that FIG. 14 also shows an example of the case where the tube to be locked is the multi-lumen tube 253 in which various tubes are integrated, and such a multi-lumen tube may be used. . Similarly, each of the above examples is basically applicable to the multi-lumen tube. In each of the examples of FIGS. 7 to 14 described above, the same effect as that described in the example of FIG. 6 can be obtained as a means for locking each conduit tube extending from the endoscope cover with a channel.

5 to 14 show specific examples of the mode of locking and the means thereof, the present invention is not limited to this through each example, and the following may be performed. That is, the locking member 234 does not have to be provided on all of the operating portion 155, the universal cord portion 232, and the connector portion 164 of the cover endoscope 7 as shown in FIG. At least one of them may be used. Further, even when the locking members 234 are provided in two or more of the operation section 155, the universal cord section 232, and the connector section 164, they need not all be of the same type. Any locking means suitable for the shape of the part to be applied may be used. Further, when the locking member 234 is provided on the operation portion 155, as shown in FIG. 15, the locking member 234 may be provided on the side of the mold-shaped operation portion cover 254. As shown in FIG. 15, it can be seen that the suction, air supply, and water supply conduit tubes extending from the insertion section cover are locked and regulated.

Next, with reference to FIGS. 16 to 19, a suitable configuration example will be described when a sheet-like one is used as the operation unit cover 12 (for example, in the case of FIG. 5). FIG. 16 is an example of a development view of the sheet-shaped operation unit cover 12. In the case of this development view shape, the operation unit cover 155 is wrapped around the operation unit 155 of the cover endoscope, for example, as shown in the direction of the arrow. Then, the operation portion 155 is covered (rolled up behind the paper). With the sheet-like operation portion cover 12 shown in FIG. 16, it is difficult to find the end portion when removing. Therefore, each of the examples of FIGS. 17 to 19 provides a sheet-shaped operation portion cover 12 that is easily removable, based on the difficulties.

That is, of the endoscope cover 10 with a channel for contamination prevention which includes the insertion section cover section 11, the operation section cover 12, and the universal cord cover 13, the sheet-like operation section cover 12 has an edge indicating an edge. This is achieved by providing. The indicating means is preferably a color, preferably a specific shape such as a convex portion or a concave portion, and preferably a letter or a symbol.

In the case of FIG. 17, the edge of the sheet-like operation portion cover 12 is colored. Here, the edge color 269 may have the same color all around, or as shown in the figure, the ranges of U, V, and W may be color-coded. This makes the edges easier to find and easier to remove. In the example of FIG. 18, a convex portion 255 is attached to the edge of the sheet-shaped operation portion cover 12. Alternatively, for example, a recess or the like may be used. In the case of FIG. 19, characters / symbols 270 (in the illustrated example, arrows, crosses, etc.) are attached to the edges of the sheet-like operation portion cover 12. These examples also have the same effect as described above, and as a result of easily finding the edge, this can be easily performed when the sheet-shaped operating portion cover 12 is removed. These can be implemented by further adding to the configuration in the case of FIG. In this case, not only when the operation unit cover 12 is attached, but also when it is removed, the handleability is improved.

Next, FIG. 20 shows a configuration example suitable as a hanger of the cover endoscope 7. As shown in the figure, the hanger 256 includes a column 257, a universal cord side holding portion 258, an angle shaft holding portion 259, and a fixing member 260. The universal cord side holding portion 258 and the angle shaft holding portion 259 are fixed. The universal cord side holding portion 258 and the column 257 can be fixed so that the position can be adjusted by the fixing member 260. Further, the portion of the universal cord side holding portion 258 in which the portion on the universal cord portion 232 side is accommodated has a recess 258a shape.

As also shown in the upper part of FIG. 20, the configuration of the cover endoscope and the operation portion cover applied here is a detachable mold-like shape that is almost the same shape as the cover endoscope 7. It has a structure in which an operation section cover 254 and a detachable angle knob 150 are attached. The molded operation portion cover 254 can be divided into, for example, the knob 150 side and the other side with the dividing surface 271 as a boundary.

Although not shown here, a control wire extending from a curved portion at the tip is guided into the endoscope 7 for the cover, which is a sprocket for UD (up and down) and a RL (for left and right). ) Each is connected to the sprocket via a chain. Each of the angle shafts 272 for rotating the UD sprocket and the RL sprocket has a double structure inside and outside, and as shown in the lower part of FIG. It protrudes out of the cover 254. The clearance between the angle shaft 272 and the cover endoscope 7 is, of course, watertight, and the angle shaft 272 and the angle knob 150 can be attached simply by inserting the angle knob 150 into the angle shaft 272. It has become.

As shown in the upper part of FIG. 20, the distance from the center of the universal cord part 232 to the inside of the attached angle knob 150 is set to be l2, while as shown in the lower part of FIG. Assuming that the distance L2 is from the center of the recess 258a of the side holding member 258 to the outer surface of the angle shaft holding member 259, the hanger 256 is such that the relationship of l2 <L2 is established between them. That is, the hanger 256 is configured so that l2 <L 2. According to the above configuration, after the inspection is completed and before the operation section cover (which is also disposable) to be discarded is removed, the cover endoscope 7 is simply hung on the hanger 256, and the angle knob is displayed as shown in the lower portion of FIG. 150 comes off, saving you the trouble of removing knob 150 by hand. That is, the knob 150 may be applied to the angle shaft holding member 259, and in that state, the knob 150 may be pulled away and applied to the concave portion 258a of the universal cord side holding member 258. Can also be shortened. After that, it is easy to remove the control cover. The above example of the hanger 256 having the function of removing the angle knob 150 can be implemented in combination with, for example, the configuration shown in FIG.

Next, with reference to FIG. 21 to FIG. 25, in a cover type endoscope, a configuration suitable for enabling both direct-view observation and side-view observation even with the same cover endoscope. An example will be explained. FIG. 21 shows an example of the insertion portion cover portion 11 in the case of a side-view type cover, and FIG. 24 shows a case of a direct-view type for comparison with this. 22 and 23 are AA and BB sectional views of FIG. 21, and FIG. 25 is a CC sectional view of FIG.

In FIGS. 21 and 24, the applicable cover endoscope 7 is the same in any case, and this configuration uses one cover endoscope 7 as the insertion portion cover portion 11 By selectively replacing the direct-view type and the side-view type with each other, it is intended to enable direct-view and side-view observation. In the case of the side-view type, the tip portion 9 of the cover is configured as shown in FIG. 21, and the inclined forceps outlet 120 also used for guiding the treatment tool is opened as shown in FIG. Also, on the surface, as in the direct-viewing type in FIG. 2, there is an observation window 16, which is provided on the side surface, and the image is provided under the observation window 16 as shown in FIG. It is adapted to be guided to the observation optical system 21 of the inserted cover endoscope 7 via the prism 262. A mirror may be used instead of the prism 262 as means for converting the visual field to the side (see FIG. 26). On the other hand, as shown in FIG. 23, the light emitted from the illumination optical system 116 of the inserted cover endoscope 7 passes through the optical member 263 provided at the tip 9 of the cover and is emitted from the observation window 16. It is emitted into the body cavity.

On the other hand, in the case of the direct-view type shown in FIG. 24, the structure of the tip portion 9 of the cover is shown in FIG. 25, but the insertion cavity for the cover endoscope to be inserted is as follows. The shape is set so that both types can be used in common. That is, the shape of the insertion cavity 264 (see FIGS. 24 and 25, and FIGS. 21 and 23) of the cover endoscope 7 between the front-end portion 9 of the direct-view type cover and the front-end portion 9 of the side-view type cover is changed. It is configured such that they are the same among each other.

In this way, one cover endoscope 7 can be applied to either type of insert cover portion 11, and therefore separate cover endoscopes for direct viewing and side viewing are prepared. Even if it is not necessary to use the single cover endoscope 7, even if the view direction itself is direct, it is only necessary to change the insert cover 11 that should be used in combination. The inspection can be performed in any of observation, treatment, side-view observation, and treatment, and the above-described configuration can obtain such an advantage as an endoscope with an endoscope cover system with a channel.

Next, with reference to FIG. 26 and the following, an example of a preferable configuration of a system using a cover-type endoscope including image inversion processing when a side-view type cover is used will be described. FIG. 26 shows a configuration in which a mirror 265 is used in place of the prism (FIG. 23) as the visual field lateral conversion means in the tip portion 9 of the side-view type cover shown in FIGS. In the case of the side-view type cover having such a structure, the image is upside down, which makes observation and treatment difficult. Therefore, the following endoscope system aims to correct the upside-down inversion of the image by the mirror 265 and to facilitate observation and treatment even when a side-view type cover using the mirror 265 is used. .

That is, in the present system, a side-view type cover for changing the field of view using the mirror 265, a cover endoscope 7 with a built-in solid-state image sensor, which is inserted into the side-view type cover, An image inverting means is provided in an endoscopic device including a video processor 3 (FIG. 1) for inputting an output from an image pickup device. Preferably, the image inverting means is a memory section in the signal processing system of the video processor 3, and the memory section is provided with image inverting processing means for inverting the reading order or the writing order of the memory for each line. Comprises. Further, it is preferable that the image reversing means is configured by providing a CCD capable of reverse reading as the solid-state imaging device.

FIG. 27 shows, as a functional block, a signal processing flow until an image is displayed on the monitor 6 (FIG. 1) based on a signal from the CCD 280 of the image pickup unit 108 of the cover endoscope 7. The preprocessing unit 281, the A / D conversion unit 282, the memory unit 283, the D / A conversion unit 284, and the host process unit 285 constitute a signal processing circuit in the video processor 3. Here, the memory unit 283 is provided with an image inversion processing unit capable of reversing the reading order or the writing order of the memory for each line when necessary, by which the Correction of image inversion by the mirror 265. By doing so, the image is inverted, and therefore, the observation and processing can be performed as usual on the monitor screen after the image inversion processing. Also, instead of the above, the same effect can be obtained by using a CCD 280 that can be read backward, and even in the case of the side-view type using the mirror 265, observation and processing can be facilitated.

Further, when the image reversing means is provided in the endoscope apparatus as described above, in addition to this, it is preferable to provide a display means indicating that the image reversing process is being performed. This is to confirm whether the mirror 265 is currently performing the reversal process to correct the upside-down reversal of the image (it is not necessary for the direct-view type cover). For the sake of simplicity, examples are shown in FIGS.

In the example of FIG. 28, a display lamp 266 is provided on the panel of the video processor 3 and is lit, for example, when the reversing process is performed when the side view type cover is combined. A person who comes into contact with the display during the image reversal process by the display lamp 266 clearly recognizes that fact, and therefore can certainly know that the image on the monitor 6 is actually the one after the reversal process. Here, the lamp display mode may be blinking, or conversely, it may be turned on when the reversing process is not performed, and may be turned off to notify that the image reversing process is being performed. In the case of FIG. 29, for example, the character “reverse” is displayed on the screen of the monitor 6 to warn the user of the reversing process. In this case, the same effect can be obtained. In addition to the above examples, the main display may be, for example, a voice display, or a visual display and an auditory display may be used together. The system of FIG. 1 may include the processing / display described above.
