It is held by holding means. In FIG. 1, the upper cushioning material 6 is shown as being separated from the lower cushioning material 3.

The case body 2 is open at the upper side, for example.
This opening can be closed by a case upper lid 8 connected on the rear end side. A handle 9 is provided on the front side surface of the case upper lid 8. The handle 9 is put on the case upper lid 8 from above so as to close the opening of the case main body 2.
By passing the handle 9 through the handle hole 10 provided on the front side surface of the case, the case upper lid 8 is prevented from opening, and the storage opening of the case body 2 can be closed. The case body 2 as an exterior material can be manufactured at a low cost, for example, and is made of corrugated cardboard which is a raw material of recycled paper and a flammable material.

The lower cushioning member 3 housed in the case body 2 and holding the endoscope 7 is a plate-like lower cushioning member forming member 3 '(simply referred to simply as a forming member) 3' as shown in FIG. 3 are bent at right angles as indicated by arrows A and B along the bending lines 11 on both ends thereof to raise both ends, and a plurality of portions of the surrounding bent piece 12 shown in FIG.

In this case, each part of the endoscope 7 is pushed into the concave portion 4A at the center of the upright U-shaped holding piece 4 so as to be clamped, so that the endoscope 7 is almost positioned so as not to rattle. A holding portion having a function of holding elastically and holding with a cushioning material against vibration or the like is formed.

The upper cushioning member 6 can also be formed by a simple process from a plate-shaped upper cushioning member (not shown). That is, as in the case of the forming member 3 ', the upper cushioning member forming member is bent at right angles along the bending lines on both ends thereof to raise both ends, thereby forming the peripheral bent piece 12' shown in FIG. An upper cushioning member 6 having an opening 5 shown in FIG. 4 formed by providing a cutout hole at a position where the U-shaped holding piece 4 of the cushioning member 3 stands up can be formed by simple processing.

FIG. 5 shows a state in which the holding piece 4 of the lower cushioning member 3 is passed through the opening 5 of the upper cushioning member 6. Then, the interior material in this state is stored in the case main body 2 integrated with the case upper lid 8 as its packing material (or exterior material).

In this embodiment, the forming member 3 'of the lower cushioning member 3 and the forming member of the upper cushioning member 6 can be manufactured at a low cost, for example, and can be used as a raw material of recycled paper and a cardboard which is also a combustible material. It is paper.

When the endoscope 7 is stored and held, the endoscope 7 is disposed between the lower cushioning member 3 and the upper cushioning member 6 shown in FIG. Each part of the endoscope 7 is held in a partially held position.

FIG. 6 shows an endoscope 7 housed in the endoscope housing case 1. The endoscope 7 has an elongated and flexible insertion section 16 and an operation section 1 provided at a rear end of the insertion section 16.
7 and a flexible universal cord 18 extending from the operating section 17, and a connector 19 detachably connected to the light source device at the tip of the universal cord 18.
Is provided.

The insertion portion 16 has a hard tip portion 20 provided at the tip, a bendable bending portion 21 provided at a rear end of the tip portion 20, and a soft bending portion 21 provided at a rear end of the bending portion 21. The rear end of the flexible tube 22 is connected to the operating section 17 via a connection ring 23, and a break preventing portion 24 is provided at the rear end of the flexible tube 22 to prevent breakage. doing.

The operation section main body 2 forming the operation section 17
5 is provided on the front side with a grip portion 26 that is gripped by an operator, and a bending operation knob 27 that bends the bending portion 21 to a position where the bending portion 21 can be operated by a hand gripped on the rear end side.
a, 27b and joystick type multi-function switch 2
8 are provided. Then, the bending operation knob 27a,
By rotating the 27b, the bending portion 21 is moved up and down,
Can be curved left and right.

Further, the endoscope 7 does not have a large number of switches for operating on / off of the air supply, water supply, and suction functions and on / off operations such as freeze and release. , A function of turning on / off a water supply / suction function and on / off of a freeze, release, etc.) can be operated by a joystick type multi-function switch 28. Further, the effect of reducing the weight, size, and cost of the operation unit 17 can be obtained.

A treatment instrument insertion port 29 for inserting a treatment instrument is provided near the front end of the operation section 17. Flexible tube section 22
In the same manner as the formation of the buckling preventing portion 24 at the connecting portion with the operating portion 17 at the rear end, the connecting portion of the universal cord 18 to the operating portion 17 at the base end is provided with the buckling preventing portion 30 and operated by the connection ring 31. It is connected and fixed to the part 17. Also, a connecting portion with the connector 19 provided at the end of the universal cord 18 is provided with a buckling preventing portion 32 and connected and fixed to the connector 19 by a connecting ring 33.

In the endoscope 7, the buckling prevention portions 24, 30,
32 are all formed of a common buckling member having the same shape to reduce the cost. Note that, due to a difference in the thickness of the flexible tube portion 22 and the like, the buckling prevention portion 24 and the buckling prevention portions 30 and 3 are provided.
When it is difficult to use the buckle 2 in common, the buckling stoppers 30 and 32 may be used in common. In other words, the cost is reduced by sharing at least two buckling portions. At this time, it is even better if the connecting rings 23, 31 and 33 are made common. (The cost can be reduced by common use.) The structure of the universal cord 18 is made easy to return to torsion, so that the operator does not get in the way due to the twisted state when performing endoscopic examination. As shown in FIG. 7A, the cross-sectional structure of the portion indicated by reference symbol D in FIG.
8a + the resin tube 18b, or as shown in FIG. 7B, the blade 18c + the resin tube 18b.

The resin tube 18b is also made of a material such as urethane or silicone elastomer, which has sufficient flexibility and is easy to recover from torsion. By doing so, the universal cord 1
The eight portions can be freely bent so as not to disturb the inspection during the endoscopic inspection, and have sufficient flexibility even if torsion occurs, so that the torsion can be eliminated.
The universal cord 18 may be made of a material that can be freely twisted.

Further, in the present embodiment, the endoscope 7 is stored and held so as to be covered with a protection member 34 as shown in FIG.

As shown in FIG. 8A, the protective member 34 covers the sheet-like protective member 34, for example, by winding it around the outer peripheral surface of the insertion portion 16, as shown in FIG. The protective member 34 covers the entire periphery of the distal end side of the insertion portion 16 so that damage can be prevented. Note that the protection member 34 is not limited to a sheet-shaped member and may be a cylindrical member.

The protective member 34 is made of a conductive or conductive material in order to prevent damage to the electronic components such as the solid-state imaging device disposed in the distal end portion 20 of the insertion section 16 of the endoscope 7 due to static electricity. An electronic component is formed by using a non-charging material to prevent electrostatic charging, or by using a paper or the like coated with an antistatic agent such as an amine-based surfactant for the protective member 34, thereby making the electronic component electrostatic. May be provided with a function of preventing destruction or the like.

The endoscope 7 in which the distal end of the insertion portion 16 is covered with the protective member 34 is held by the lower cushioning material 3 as shown in FIG.
Is stored in.

As shown in FIG. 9, the center 17A of the operation unit 17
Is eccentrically arranged on one side (the upper side of the paper surface in FIG. 9) of the lower cushioning member 3 having a rectangular shape, the two holding pieces 4 hold the vicinity of the connection ring and the vicinity of the base end side of the insertion portion 16 and are eccentric. A universal cord 18 protrudes from the side of the operation unit 17 on the side opposite to the side. A wide space is secured in the direction in which the universal cord 18 protrudes, and the protection member 34 and the like are held by the plurality of holding pieces 4 in a state where the insertion portion 16 is bent.
Is also held in a loop shape by the plurality of holding pieces 4.

That is, the universal cord 18 and the connector 19 are arranged on the side of the universal cord 18 in the projecting direction from the center 17A of the operation section 17, and the insertion section 16 is also arranged and held on the same side. Thus, the endoscope storage case 1 can be reduced in size and weight. In addition,
In FIG. 9, a hatched portion indicates a cut 13 (the same applies to FIG. 20 described later).

By minimizing the size of the storage material for the endoscope as described above, the occupation rate (transparent area ratio or filling rate) of the endoscope 7 when the interior material is viewed from above is 10%. That's it. On the other hand, in the past, there was more clearance and lower occupancy. In this embodiment, the transportation cost can be reduced by making the device more compact.

In FIG. 8 or FIG. 9, the distal end portion of the insertion section 16 is covered and protected by the protection member 34. However, the operation section 17, the universal cord 18, The connector 19 and the like may be protected. Further, all or a part of the holding portion 4A may be protected, or the holding portion 4 or the protection member formed of an elastic member having elasticity may be attached to the holding portion 4 or the recess 4A. You may make it protect a part.

For example, in FIG. 9, a protection member 35 formed of a rubber member or the like is attached to one concave portion 4A. For example, when the outer peripheral surface of the insertion portion 16 is directly clamped, strong vibration or the like is applied. If there is a possibility that the pinched portion may be damaged, it can be protected from being damaged. The protective member 35 is formed by bending a resilient or soft cushion member such as a sponge into a U-shape and attaching it to the concave portion 4A, and the insertion portion 16 of the endoscope 7 there.
Or the like may be pushed in and pinched.

In this embodiment, an interior material having a holding portion for holding a plurality of portions of the endoscope 7 by holding the endoscope 7 is provided.
It is characterized in that a notch 13 or the like is formed in a plate-shaped member and can be easily formed by bending.

In this case, the cut 13 provided in the plate-shaped member
By bending the base end portion of the base member to erect the cut piece, the holding piece 4 having the holding recessed portion 4A can be formed, and the interior of the block-shaped member is significantly less than in the case where the storage groove is provided in the block-shaped member as in the conventional example. Only wood.

Therefore, the amount of corrugated cardboard used as a material for the interior material can be reduced. Further, in the present embodiment, if the holding piece 4 is laid down and stored in the cut 13, or if the surrounding bent piece 12 is laid down without being raised, the lower cushioning member 3 can be formed into a plate-like member, and If the cushioning member 6 is also laid down without the surrounding bent piece 12 ′ standing up, it can be made into a plate-like member, so that it can be stored in a smaller storage space as compared with the conventional example.

That is, when the endoscope 7 is detached from the interior material and the endoscope 7 is stored in another storage place, and the interior material is temporarily unnecessary, the endoscope 7 is stored in a plate shape. The storage space for that is small. For this reason, storage costs can be reduced. Also, for example, even when this interior material is completely unnecessary, it can be reused as recyclable recycled paper.

Also, by using the endoscope storage case 1 as a returnable box for delivery of endoscopes between the hospital and the store and / or between the store and the warehouse, unnecessary storage materials can be used. It is possible to prevent taking up space in an inspection room and a store.
In such a case, the cost and the selling price of the product can be reduced for the case.

For example, the store stores the endoscope storage case 1
The endoscope 7 is stored and transported to a hospital or the like, and the endoscope 7 is taken out of the endoscope storage case 1 and delivered only to the endoscope, and the endoscope storage case 1 is brought back to the hospital. It can also be used as a box.

When a user requests repair, a sales clerk brings the case 1 to the user, stores and holds the endoscope in the case 1, and returns the case. Then, it is transported to the maker for repair, and is transported again to the user in the case 1 to deliver the repaired endoscope. By using the box as a returnable box in this way, it is possible to reduce the selling price of the endoscope 7 and to reduce the repair cost at the time of repair. Also, hospitals do not need to store unnecessary case 1,
The endoscope inspection room can be used widely.

FIGS. 10A and 10B show the configuration and multifunction of an endoscope device 91 capable of controlling air supply, water supply, suction, freeze, and release by operating the multifunction switch 28 in the endoscope 7. The operation function of the switch 28 is shown.

The endoscope device 91 comprises the endoscope 7, a control device 92 to which the connector 19 of the universal cord 18 of the endoscope 7 is connected, and a monitor (not shown).
A light guide 47 is inserted into the insertion portion 16 of the endoscope 7, and a rear end side of the light guide 47 is inserted through the operation portion 17 and the universal cord 18, and projects at the connector 19 as a light guide connector 93. The light source unit 94 of the control device 92 is connected.

Then, illumination light of a lamp 95 built in the light source unit 94 is condensed and supplied through a condenser lens. The illumination light is transmitted and emitted from the distal end of the light guide 47 via the illumination optical system 48 to illuminate a subject such as an affected part.

The illuminated subject forms an image on the image pickup device of the image pickup unit 45 by the objective optical system 43 and is subjected to photoelectric conversion. The total cable 6 connected to the imaging unit 45
5 is connected from the connector 19 to a video converter 96 in the control device 92. Then, the image pickup signal of the image pickup device is subjected to signal processing, converted into a video signal (video signal), output to a monitor (not shown), and displayed as a subject image. A freeze / release control circuit 97 for controlling the freeze / release is connected to the video converter 96.

The air is supplied to the outer surface of the objective optical system 43
The air supply / water supply tube 98 provided with the water supply nozzle 50 at the distal end is separated into an air supply tube 99 and a water supply tube 100 at a branch portion near the distal end of the insertion portion 16. An air supply base 101 and a water supply base 102 are reached. Air supply base 101 and water supply base 102
Are respectively connected to the air supply means 103 and the water supply means 104 via tubes.

That is, the air supply base 101 is connected to the air supply opening / closing valve (V1 in FIG. 10A) 105 and the air supply pump 106 via the tube. In addition, water supply mouth 102
Is a water supply on-off valve via a tube (V in FIG. 10A).
2) 107, water tank 108, water pump 109
And connected to.

The treatment instrument insertion port 29 communicates with the treatment instrument insertion / suction channel 111 inside, and the treatment instrument insertion / suction channel 111 becomes a channel opening 51 at the tip of the insertion section 16, and the universal cord 18 is located near the hand side. Through the inside, it reaches the suction base 112 of the connector 19.

This suction base 112 is connected to suction means 113 via a tube. In other words, the suction opening / closing valve (V3 in FIG. 10A) 114, the suction tank 115, and the suction pump 116 are connected via the tube.

The air supply opening / closing valve 105 and the air supply pump 1
06, the water supply on-off valve 107, the water supply pump 109, the suction on-off valve 114, and the suction pump 116 are connected to an air supply / water supply / suction control circuit 117 for controlling air supply, water supply and suction by a control signal line 118, Air / water / suction control circuit 11
The operation can be controlled by a control signal from the control unit 7.

As shown in FIG. 10A, the multi-function switch 28 provided on the operation unit 17 can be tilted about the shaft of the multi-function switch 28 back and forth, right and left, etc., with the base end as the center of rotation. The multi-function switch 28 is provided with a watertight waterproof rubber 1 to prevent water from entering inside even when the tilting operation is performed.
It is attached to the operation unit 17 via 21.

A plurality of switch contacts 122, specifically five switch contacts 122 are provided near the base end of the shaft of the multi-function switch 28. When the multi-function switch 28 is tilted, it is arranged on the side opposite to the tilting direction. The switch contact 122 is turned on.

Specifically, as shown in FIG. 10 (B), when tilting to the front side, right side, left side, rear right side, and rear left side,
The contact for suction, the contact for air supply, the contact for water supply, the contact for freeze, and the contact for release are each turned on.

These switch contacts 122 are connected to the freeze / release control circuit 97 in the control device 92 and the air / water / suction control circuit 1 via the switch signal cable 123.
17. Then, a control operation corresponding to the switch contact 122 that is turned on is performed.

It should be noted that in FIG.
The water supply tube 100 and the water supply tube 100 are joined at the distal end side of the insertion portion 16 to form one air supply / water supply tube 98. May be good.

With the structure shown in FIG. 10A or a modified example, there is no need to provide an air / water cylinder in the operation unit in the conventional example, and it is not necessary to provide a connector for connecting to a water tank in the connector. The cost can be reduced by reducing the number of parts.

Further, by providing the multi-function switch 28, the cost can be reduced because only one multi-function switch 28 is required without providing each of the air / water supply button, the suction button, the freeze switch, and the release switch. The operation unit 17 can be made compact and lightweight.

In the specific example shown in FIG. 10, the multi-function switch 28 has a function of an air / water button, a suction button, a freeze switch, and a release switch. However, the present invention is not limited to this, and may have a plurality of functions. If they have the same effect, they have almost the same effect. Further, the present invention is not limited to the one provided with the switch function in five directions, and can be applied to the one provided with the switch function in two or more directions.

FIG. 11 shows the bending portion 21 of the endoscope 7.
The concrete structure of is shown. As shown in FIG. 11A, a distal end cover 75 is attached to the front end of the distal end body 41 forming the distal end portion 20 of the endoscope 7.

An image pickup unit 45 having an integrated objective optical system is attached to the distal end body 41, and a channel opening 51 is provided adjacent to the image pickup unit 45.

A frontmost first bending piece 76 for forming the bending portion 21 is fixed to the outer peripheral surface of the rear end of the front end body 41 by screws (not shown), brazing, or the like.
The second bending piece 76 is connected to the rear end of the second bending piece 7 via a rivet 77 as a rotatable connecting member.
A number of bending pieces 76 are rotatably connected to the third bending piece 76 via a rivet 77 at the rear end of the flexible pipe 6, and the rear end of the bending piece 76 at the rearmost end is in front of the flexible tube. It is fitted to the base 78 and is fixed by screws or brazing (not shown) similarly to the tip side. Each bending piece 76 has a substantially annular shape,
Each bending piece 76 has a connecting portion connected by a rivet 77 projecting in a semicircular shape.

The outer circumference of the bending piece 76 is covered with the bending portion covering tube 52 and is fixed water-tight at the front end 20 and the front end of the flexible tube 22. The flexible tube portion 22 is covered with a triple covering member of a flex 79, a blade 80, and a waterproof flexible resin tube 81.

Also, four coil pipes 82 are inserted into the flexible tube portion 22 as wire guides for up, down, left, and right.
In each coil pipe 82, a wire 83 for drawing a curved portion is inserted. The distal end of each coil pipe 82 is fixed to the flexible tube front base 78 by brazing or the like, and each wire 83 is extended forward in a state where each wire 83 is exposed from this portion.
Is firmly fixed to the first bending piece 76 by brazing or the like.

In this case, each wire 83 is restricted from being shifted from the inserted axial direction by passing through a wire insertion ring 84 fixed to the inner wall of the bending piece 76 through which the wire 83 is inserted. The rear end of each of the wires 83 is attached to a sprocket (not shown) in the operation section 17 in a pair, and by rotating the bending operation knobs 27a and 27b, the sprocket is rotated to form the pair of wires 83.
The wire 8 to be pulled by pulling one of the
The bending portion 21 can be bent to the third side.

Conventionally, the bending angle is adjusted using a stopper in the operation unit. However, there are drawbacks in that the man-hour for assembling is increased and the operation unit is increased in size. Thus, the assembling work can be simplified, and the operation unit does not need to be large.

That is, the bending piece 7 adjacent with the rivet 77
The front end or the rear end (referred to as a shoulder opening for simplicity) of the bending piece 76 around the connecting portion that is rotatably connected to 6 is formed such that the notch amount increases in a tapered shape as the position becomes farther from the connecting portion. It is notched (that is, the angular position different by 90 degrees from the connecting portion has the largest notch amount).

In the case of the endoscope 7, when the wire 83 is pulled to bend the bending portion 21 to a predetermined bending angle or more as shown in FIG. 7
6 so that the shoulder openings 76a of the adjacent bending pieces 76 abut against each other so that the shoulder openings 76a are not bent beyond the angle at which the shoulder openings 76a abut each other. .

Further, almost no adjustment work of the bending angle is required. In other words, the notch shape of the shoulder opening 76a of each bending piece 76 is set in advance according to the required maximum bending angle, and if the shoulder opening 76a is bent beyond the maximum bending angle, the shoulder opening 76a is formed.
When a strikes, it restricts not to bend more than the angle.

In addition to using the shoulder opening 76a of the bending piece 76, the following procedure may be used. The bending mechanism in the operation unit is constituted by a rack and pinion in order to make the moving stroke of the wire 83 constant. The effect in this case is that the rotational motion can always be converted into a certain linear motion, so that the member for angle adjustment and the operation thereof are not required. Therefore, the assembling operation can be simplified, and the adjustment operation of the bending angle can be eliminated.

The length of the four wires 83 is the same for all four wires. When the lengths of the four wires 83 used for the endoscope 7 are the same, there is no difference in the length of the wires 83 alone, so that when bending, even if the bending angle adjusting mechanism is eliminated, the length is always constant. , And the angle of curvature is always constant. Therefore,
The assembling work can be simplified, and the work of adjusting the bending angle can be eliminated.

The allowable range on the maximum bending angle side is roughened.
For example, in the case of an endoscope for observing a large intestine, the upward direction is 180 °. For example, 18
Fine adjustment to 0 ° is unnecessary, and rough adjustment is sufficient. Therefore, since the time for performing the adjustment is shortened, the assembling operation can be simplified.

As the endoscope 7 described above, FIG.
With the structure shown in FIG. 13, while cooling the imaging means incorporated in the distal end portion 20, and cooling the periphery of the illumination optical system by providing an air supply and water supply mechanism, the heat generation of the distal end portion 20 is suppressed.

2 shows a cross section of the line.

The illumination optical system 48 including the front end of the light guide 47 is fitted via a lens frame 46 into two through holes provided adjacent to the through hole in which the objective optical system 43 is mounted. The fitting portion is water-tightly fixed with a water-tight fixing adhesive 49.

An air / water nozzle 50 is provided so as to face the outer surface of the objective optical system 43.
If the outer surface of 3 is dirty and it is difficult to observe, the air or water is supplied to remove the dirt.

The distal end main body 41 is provided with a channel opening 51 serving as an outlet for the treatment tool and serving as a suction port when a suction operation is performed.

As shown in FIG. 13, the distal end of the curved portion covering tube 52 covers the outer peripheral surface of the distal end portion main body 41, and the curved portion covering tube 52 is water-tightly fixed with an adhesive 49 for watertight fixing.

The front end of the light guide 47 is fixed to the lens frame 46 via a base, and the front end of a coating tube 53 such as a thin silicon tube for covering and protecting the light guide 47 is attached to the rear end of the base. It is fixed with an agent.

Outside the covering tube 53, a cooling air supply / water supply passage 55 composed of a double waterproof tube 54 is formed. The tip of the inner tube of the double waterproof tube 54 is fixed to a base, and Are fixed by a cylindrical fixing portion projecting from the rear end of the distal end main body 41.
