Description

  The present invention relates to an endoscope storage case for examining living tissue and a storage case storing an endoscope.

  Today, endoscopes are used to examine living tissue inside the human body. An endoscope is often stored or transported in a state of being stored in a storage case. As a conventional storage case, for example, there is a case in which a case main body and a cover are made of a foam material, and a storage groove in which each part of the endoscope can be inserted and stored from the surface of the foam material. The shape of the storage groove is set in accordance with the shape of each part of the endoscope.

For example, there is a known carrying case for endoscopes that is low in manufacturing cost, lightweight, convenient to carry and transport, and does not deteriorate the appearance of the endoscope that is stored, and does not impair insertion into the body. (Patent Document 1).

JP 2006-141810 A

  The endoscope carrying case includes a container and a lid. The endoscope having a flexible tube and a light guide conducting tube is housed in a housing groove provided in the container, and the housing groove is closed by the lid. Is. The endoscope carrying case has a configuration in which at least one of the container and the lid is fusion-molded with a molding die using a resin foam bead material, and at least a part thereof is provided with a transfer preventing means. As a result, uneven patterns due to the fusion boundary of resin foam beads are not transferred to the surface of the endoscope, especially the flexible tube and the light guide conducting tube of the endoscope housed in the endoscope carrying case, ensuring insertability. It can be done.

  On the other hand, considering that the endoscope is inserted into the human body, the outer diameter of the flexible tube (flexible cable) is preferably small and highly flexible. In particular, since the endoscope for bronchi or otolaryngology passes through a narrow region, the outer diameter of the flexible tube (flexible cable) is the flexible tube (flexible cable) in the endoscope for digestive tract. ) Is smaller than the outer diameter. As described above, the type of endoscope that is applied to each examination target region is determined for the endoscope, and the outer diameter of the flexible tube (flexible cable) varies depending on the type of endoscope.

  In a storage case for storing such an endoscope, a storage body made of, for example, foamed resin having a high cushioning property provided with a storage groove that matches the shape of the endoscope is used. However, as described above, it is cumbersome to design, manufacture, and prepare a storage case for each type of endoscope having a different shape depending on a region to be inspected, which is not preferable from the viewpoint of manufacturing cost. For this reason, it is common to use a common storage case regardless of the type of endoscope.

  For this reason, when endoscopes with different outer diameter dimensions of the flexible tube (flexible cable) depending on the inspection target part are stored in a common storage case, due to the difference in outer diameter dimension of the flexible tube (flexible cable), A flexible tube (flexible cable) is easily bent or has a tendency to bend. Specifically, since the groove width of the storage groove for storing the flexible tube (flexible cable) corresponding to the flexible tube (flexible cable) having the largest outer diameter size is defined, In the tube (flexible cable), a large gap is generated in the storage groove, and the flexible tube (flexible cable) is not fixed in the storage groove and easily moves laterally in the groove width direction. For this reason, the flexible tube (flexible cable) is held straight and stored in the storage case. It is easy to bend or bend. When a flexible tube (flexible cable) that is curved or has a curved fold is inserted into the human body, the ease of insertion is reduced. Furthermore, the flexible tube (flexible cable) may be broken due to the above-described bending.

  On the other hand, in order to prevent the flexible tube (flexible cable) stored in the storage groove from moving laterally in the storage groove, a cushioning material is provided so as to cover the flexible tube (flexible cable) from above the storage groove. May be provided. In this case, the cushion material can prevent lateral movement of the flexible tube (flexible cable) in the storage groove, but it is stored in the storage groove connected to the flexible tube (flexible cable). When the operation part moves slightly, the connection part of the flexible tube (flexible cable) with the operation part may be partially curved or have a curved wrinkle. For this reason, the cushion material cannot be tightly packed in the storage groove so that the flexible tube (flexible cable) does not move laterally at all. On the other hand, when the cushioning material is not tightly packed in the storage groove, the flexible tube (flexible cable) moves laterally in the storage groove and is bent or easily bent.

On the side surfaces of the lower case body 11 and the upper case body 12, lock mechanisms (not shown) are provided for holding the closed state by engaging each other when the storage case 10 is closed. When the lower case body 11 and the upper case body 12 are closed, the upper surface 21 of the storage body 20 is covered with the cover body 30. Note that the storage case 10 can also be configured by only the storage body 20 and the cover body 30.

  The storage body 20 is provided with a groove for storing the endoscope so as to form a recess from the upper surface 21 of the storage body 20. The groove width and groove depth are set according to the shape of the endoscope.

As shown in FIG. 3, the endoscope mainly includes an operation unit 41, an insertion unit 44 mainly including a distal end portion 42 and a flexible tube 43, a light guide tube 45, and a connector unit 46. .
The example of the endoscope shown in FIG. 3 is a fiberscope that does not include a sensor for observing a living tissue at the distal end portion 42 but includes an optical system such as an optical lens and can observe the living tissue. The endoscope may be an electronic scope in addition to the fiberscope. In the case of an electronic scope, the distal end portion 42 includes a sensor for observing a living tissue, specifically, an image sensor, or an image sensor and an ultrasonic probe. An objective lens, an illumination lens, and the like for imaging by the imaging element are provided on the operation unit 41 side of the distal end portion 42.

The insertion portion 44 is provided with a bending portion (not shown) that is bent in the vertical direction and the horizontal direction. A portion closer to the operation portion 41 than the bending portion is a flexible tube 43 that can be bent by its own weight or by a direct operation of the practitioner.
The flexible tube 43 includes a signal line extending from the sensor of the tip portion 42, a sending / suction tube for sending fluid such as water and air from the tip portion 42 or sucking fluid, and illumination light for illuminating the biological material to be observed Various pipes such as an optical fiber cable for transmitting are provided. When the endoscope includes a fiberscope, the flexible tube 43 is provided with an optical fiber bundle that transmits an observation image.

  As described above, the flexible tube 43 includes a signal line, various tubes, an optical fiber bundle, and the like. The flexible tube 43 is reinforced by, for example, a resin outer skin layer and a metal mesh layer or a metal spiral cord layer on the inner side thereof, but is configured to have flexibility because it is inserted into the human body. The outer diameter of the flexible tube 43 varies depending on the region to be examined and the purpose of use of the endoscope, and is, for example, 2 mm to 13 mm, and the range of the outer diameter is wide. For the purpose of observing and treating living tissue using an endoscope, the flexible tube 43 is thick because a dedicated tool is inserted into the human body through the flexible tube 43. The flexible tube 43 is thin only for the purpose of observing a living tissue using an endoscope.

The operation unit 41 is inserted into a switch group for operating the fluid delivery and suction and a flexible puncture needle (not shown) by the practitioner, and protrudes from the distal end opening of the distal end portion 42 to contact the living tissue. A treatment instrument insertion opening, a bending operation lever for operating the bending portion of the distal end portion 42, and the like.
An optical fiber cable extending from the flexible tube 43 to the connector unit 46 is disposed in the operation unit 41, and a signal line from a sensor extending from the distal end unit 42 to the connector unit 46 is further disposed.

  The light guide tube 45 connects the operation unit 41 and the connector unit 46. The light guide tube 45 is provided with an optical fiber cable for transmitting illumination light for illuminating the living tissue, and a signal line extending from the sensor at the distal end portion 42.

The connector portion 46 is a portion connected to a processor (not shown) that processes a signal sent from the sensor, and is a portion that sends illumination light transmitted from the processor toward the distal end portion 42 into the optical fiber cable. The processor generates and generates image data including biological tissue information by processing the signal generated by the light source unit that emits the illumination light transmitted toward the distal end portion 42 and the image sensor of the distal end portion 42. A processing device that outputs an image to a display.
Such an endoscope is stored in the storage body 20 as shown in FIG.

The housing 20 has a shape of each part so as to form a recess from the upper surface 21 in order to house each part of the distal end portion 42, the flexible tube 43, the operation portion 41, the light guide tube 45, and the connector portion 46. A storage groove having a groove depth and a groove width corresponding to is provided. Specifically, a long flexible tube storage groove 43a that integrally stores the distal end portion 42 and the long flexible tube 43, an operation portion storage groove 41a that stores the operation portion 41, and a light guide tube 45. The housing 20 is provided with a light guide tube housing groove 45a for housing the connector portion and a connector portion housing groove 46a for housing the connector portion 46.
In addition, an accessory part storage groove 47a for storing accessory parts attached to the endoscope is provided.

  With these storage grooves, the groove width and groove depth are variously different corresponding to each part of the endoscope. As described above, the groove width of the flexible tube housing groove 43a is set to a groove width corresponding to the maximum outer diameter dimension among the outer diameter dimensions of the flexible tube 43 that differs depending on the type of endoscope. Therefore, the flexible tube 43 having a small maximum outer diameter easily moves laterally through the gap in the flexible tube storage groove 43a, and the flexible tube 43 is easily bent or has a curved wrinkle. For this reason, the groove cross section of the flexible tube storage groove 43a of the present embodiment has a shape as described below.

FIGS. 4A to 4C are diagrams illustrating an example of the arrangement of a plurality of flexible tubes 43 having different groove diameters and outer diameters of the flexible tube storage grooves 43a.
As shown in FIGS. 4A to 4C, the groove section of the flexible tube storage groove 43a has a tapered portion 43b in which the groove width decreases from the upper surface 21 of the storage body 20 in the groove depth direction. The groove width refers to the length between opposing groove walls at each position in the groove depth direction. According to the illustrated embodiment, the tapered portion 43b has inclined surfaces 52 that are inclined to different sides on both sides (left and right sides in the drawing) of the groove with respect to the groove depth direction. As shown in FIGS. 4 (a) and 4 (b), the two inclined surfaces 52 inclined to different sides allow the flexible tube 43 to be inserted into the flexible tube storage groove 43a even if the outer diameter of the flexible tube 43 is different. Can be positioned and positioned within.
Further, as shown in the drawing, the deepest portion of the flexible tube housing groove 43a is provided between the inclined surfaces 52 that are the groove wall surfaces of the tapered portion 43b facing each other. For this reason, the flexible tube 43 is difficult to abut at a position other than the abutting position of the groove wall surface of the tapered portion 43b. In this case, the flexible tube 43 is reliably positioned at the contact position of the groove wall surface by its own weight, and lateral movement in the groove width direction is suppressed.
In other words, the flexible tube 43 abuts at two contact positions in the groove width direction of the flexible tube storage groove 43a, and the flexible tube 43 is a flexible tube between the two contact positions in the groove width direction. It is preferable not to contact the wall surface or the bottom surface of the storage groove 43a. Thereby, the flexible tube 43 is reliably positioned at the contact position of the groove wall surface by its own weight, and lateral movement in the groove width direction is suppressed.

  As shown in FIGS. 4A to 4C, the groove cross-sectional shape of the tapered portion 43b is preferably V-shaped, but may be U-shaped instead of the V-shaped as described later. It is preferable from the viewpoint of suppressing the lateral movement of the flexible tube 43 in the flexible tube storage groove 43a.

  When the storage case 10 is transported or stored in a vertically arranged state as shown in FIG. 5A, in order to suppress the lateral movement of the flexible tube 43 in the flexible tube storage groove 43a, The flexible tube storage groove 43a is preferably provided with a tapered portion 43b from the opening of the flexible tube storage groove 43a. Specifically, the groove cross-sectional shape of the flexible tube storage groove 43a is preferably V-shaped. 5A to 5C are views for explaining the arrangement state of the storage case 10 and the position of the flexible tube 43 in the flexible tube storage groove 43a. As shown in FIG. 5B, the flexible tube 43 is positioned by the ceiling wall of the cover body 30 and the groove wall of the flexible tube storage groove 43a, and lateral movement is suppressed. As shown in FIG. 5C, when there is a vertical wall extending in the groove depth direction from the opening of the flexible tube housing groove 43a, the flexible tube 43 is not positioned depending on the length of the vertical wall and moves laterally. It may not be possible to suppress it. When a vertical wall extending in the groove depth direction from the opening of the flexible tube housing groove 43a is provided, the length of the vertical wall in the groove depth direction is set to prevent the flexible tube 43 from moving laterally. It is preferable that the length is smaller than the diameter.

  In addition to the normal arrangement state in which the lower case body 11 of the storage case 10 is located below the upper case body 12, the storage case 10 is vertically arranged as shown in FIG. In some cases, the ten lower case bodies 11 may be transported or stored in a reverse arrangement in which the lower case body 11 is located above the upper case body 12. In such a case, as shown in FIGS. 6A to 6C, the cover body 30 configured to come into contact with the upper surface 21 of the storage body 20 has an opening in the flexible tube storage groove 43 a. It is preferable that the cover body groove 30a is provided at the facing position. It is preferable that the groove cross section of the cover body groove 30a has a tapered portion in which the groove width becomes narrower as it goes in the groove depth direction. The cross-sectional shape of the cover body groove 30a is preferably the same as the cross-sectional shape of the flexible tube housing groove 43a, for example. 6A to 6C are views for explaining the position of the flexible tube storage groove 43a in each arrangement state of the storage case 10. FIG. For example, as shown in FIGS. 6A to 6C, the cross-sectional shape of the cover body groove 30a is preferably a V-shape tapered from the opening of the cover body groove 30a. When providing a vertical wall extending perpendicularly to the groove depth direction from the opening of the cover body groove 30a, the length of the vertical wall in the groove depth direction is preferably smaller than the diameter of the flexible tube housing groove 43a. . By providing such a cover body groove 30a, the flexible tube 43 is a groove wall of the flexible tube storage groove 43a of the storage body 20 in any arrangement state of the storage case 10, and the cover body wall 30a. The lateral movement is suppressed by positioning at the groove wall of the flexible tube housing groove 43a or the groove wall of the cover body wall 30a.

FIGS. 7A to 7C are diagrams illustrating an example of a state in which the flexible tube 43 having a small outer diameter is stored in the flexible tube storage groove 143 a provided in the conventional storage body 120. Since the flexible tube 43 has a flat groove bottom, it has a space that can move laterally in the groove width direction of the flexible tube storage groove 143a. For this reason, the flexible tube 43 is easy to move laterally in the flexible tube storage groove 143a. For this reason, as shown in FIG.7 (b), when the flexible tube 43 is accommodated linearly, it is easy to curve partially.
On the other hand, as shown in FIG. 7C, in a part of the flexible tube storage groove 143a, in the flexible tube storage groove 143a, the flexible tube 43 is not moved laterally in the flexible tube storage groove 143a. When the cushion material 150 is packed from the upper surface side of the storage body 120, the cushion material 150 is strongly packed in the flexible tube storage groove 143a, so that the lateral movement of the flexible tube 43 is prevented. However, when the operation unit 20 moves slightly in the operation unit storage groove, the flexible tube 43 that is prevented from lateral movement includes the portion where the flexible tube 43 is connected to the operation unit 20. The portion on the operation unit side may be bent or curved as shown in FIG. Therefore, the use of the cushion material 150 in the conventional flexible tube storage groove 143a having a constant groove width in the groove depth direction and having a flat groove bottom does not curve the connecting portion of the flexible tube 43. Is not preferable.

  On the other hand, in this embodiment, when the endoscope is stored in the storage case 10, the flexible tube 43 stored in the flexible tube storage groove 43 a is inserted into the flexible tube storage groove 43 a of the storage body 20. It is preferable to provide a cushion material 50 that covers and holds from the upper surface 21 side. By providing the cushion member 50, the movement of the flexible tube 43 in the direction of protruding from the flexible tube storage groove 43a can be suppressed. On the other hand, when the cushion material 50 is packed in the flexible tube storage groove 43a, the cushion material 50 is flexible tube so as to press the flexible tube 43 positioned from above the flexible tube storage groove 43a in which the flexible tube 43 is stored. Although it is packed in the storage groove 43a, the flexible tube 43 does not have a gap that moves laterally, and therefore gives a large reaction force to the cushion material 50. For this reason, the cushion material 50 is not stuffed into the flexible tube housing groove 43a in a state where the flexible tube 43 is strongly pressed as in the prior art. In the flexible tube 43 stored in the flexible tube storage groove 43a, the degree of restraint of movement in the direction of jumping out from the flexible tube storage groove 43a is relaxed as compared with the conventional case. Since the degree of restraint of the lateral movement of the flexible tube 43 is relaxed, the flexible tube 43 follows the lateral movement even when the operation unit 20 slightly moves laterally in the operation unit storage groove. Easy to move sideways. For this reason, it is suppressed that the part by the side of the operation part of the flexible tube 43 bends or curves.

  When the cushion material 50 is provided in the flexible tube housing groove 43a, the cushion material 50 is a quarter of the total length of the flexible tube 43 from the portion of the flexible tube 43 connected to the operation unit 41. It is preferable to be provided at a position away from the distance. Thereby, even if the degree of restraint of the lateral movement of the flexible tube 43 is strengthened by the cushion material 50, it is possible to prevent the flexible tube 43 from being bent or curved in the vicinity of the portion connected to the operation unit 41. it can.

  FIGS. 8A and 8B are views showing an example of a cross section of the flexible tube housing groove of the embodiment. In the example shown in FIGS. 8A and 8B, the groove cross-sectional shape of the tapered portion 43b is U-shaped. Even if it is U-shaped, the flexible tube 43 contacts the U-shaped bottom. At this time, even if the flexible tube 43 tries to move laterally in the groove width direction, the restoring force acts so that the flexible tube 43 comes into contact with the U-shaped bottom. Positioning within 43a and lateral movement in the groove width direction are suppressed. Further, as shown in FIGS. 8A and 8B, even if the outer diameter dimension of the flexible tube 43 is different, it can be positioned at a predetermined position of the flexible tube storage groove 43a, in the groove width direction. Suppress lateral movement. For this reason, it is possible to prevent the flexible tube 43 from being bent or bent.

  According to one embodiment, as shown in FIGS. 2 and 3, the flexible tube storage groove 43 a is preferably a groove extending linearly from the operation portion storage groove for storing the operation portion 41. If the flexible tube storage groove is curved, when the endoscope 10 is stored and held in the storage case for a long time, the flexible tube 43 is bent and a curved wrinkle is not preferable.

  Further, according to one embodiment, as shown in FIG. 9, the operation portion storage groove 41a for storing the operation portion 41 has a groove bottom of the operation portion storage groove 41a at the connection portion where the operation tube storage groove 41a connects to the flexible tube storage groove 43a. It is preferable that a step 41c is provided in the operation portion storage groove 41a so that the position of the tapered portion 43b of the flexible tube storage groove 43a is a shallow position in the groove depth direction with respect to 41b. FIG. 9 is a diagram illustrating an example of a connection portion between the operation unit storage groove 41a and the flexible tube storage groove 43a of the storage body 20.

  By providing the step 41 c, the position of the flexible tube 43 extending from the operation portion 41 in the groove depth direction is constant from the upper surface 21 of the storage body 20 when the endoscope is stored in the storage body 20. can do. That is, it is possible to suppress the flexible tube 43 extending from the operation unit 41 accommodated in the operation unit accommodating body 41a from being bent, bent, or curved with respect to the groove depth direction. In other words, in the operation side portion of the flexible tube 43 including the portion connected to the operation unit 41, the position in the groove depth direction of the flexible tube storage groove 43 a of the flexible tube 43 is the upper surface 21 of the storage body 20. It is preferable that the step 41c is provided so as to be constant, that is, the dimension of the step 41c is determined.

  As mentioned above, although the storage case of the endoscope and the storage case storing the endoscope of the present embodiment have been described, the present invention is not limited to the above-described configuration, and is within the scope of the technical idea of the present invention. Various modifications are possible.
