Description

  The present invention relates to a carrying case that stores the entire endoscope when the endoscope used for medical purposes is transported or stored.

  The carrying case for an endoscope is a case used for storing the endoscope when it is shipped, transported, stored, or the like. A carrying case is a case body and lid that are connected to each other by a connecting strip or hinge so that they can be opened and closed. These case bodies and lids are usually used from the standpoint of buffering and weight reduction. The endoscope housing recess for storing the endoscope is provided on the case body side.

  Here, the endoscope includes a main body operation unit that is manually held by an operator. The main body operation unit is connected to an insertion unit into a body cavity, and a universal cord having a connector at the distal end. Is connected to the main unit. The main body operation portion is entirely made of a hard member, and most of the insertion portion and the universal cord have a soft structure. Therefore, the endoscope accommodating recess must be able to accommodate each part of the endoscope without difficulty.

The main body operation part is accommodated at a predetermined position, and the insertion part and the universal cord extending from the main body operation part are configured to be accommodated so as to be wound in a loose loop shape in order to be accommodated in a compact manner. A thing is shown by patent document 1, for example. As described above, the carrying case storing the endoscope needs to be stored stably so as not to damage the endoscope due to vibrations acting during transportation or the like. In particular, it is necessary to prevent vibrations from acting on the endoscope main body operation section because precision components and the like are provided inside. In order to stably hold the endoscope, particularly the main body operation part, the case main body is formed with a recess for accommodating the main body operation part. Patent Document 2 discloses a configuration in which an appropriate position of the main body operation unit is positioned and held so as to be elastically sandwiched.
JP 2003-290123 A JP 11-47077 A

  By the way, as described above, the main body operation unit is elastically clamped and stored in the carrying case. If the clamping force is increased, it can be stably held in the storage state. However, if the clamping force is increased too much, it becomes difficult to take out the endoscope from the carrying case, and the clamping state cannot be released unless it is lifted by applying a strong force to the main body operation unit.

  Here, when removing the endoscope from the carrying case, it is common to first lift the main body operation unit. Since the main body operation unit is a relatively long member, and a plurality of clamping portions of the main body operation unit are formed in front and rear, it is desirable that the main body operation unit is taken out horizontally when taking out the main body operation unit. Since either of the front and rear clamping portions is released first, the front and rear are inclined to one of the front and rear. For this reason, when the holding state on the rear side of the main body operation unit is first released at the time of taking out and the front side is still in the holding state, the front end side rotates as a fulcrum. An insertion part is connected to the distal end side of the main body operation part, and the main body operation part is a hard member, and the insertion part is a soft member, so that it rises from the case with the front end part of the main body operation part as a fulcrum. become. For this reason, the connection part of the insertion part to the main body operation part is strongly pressed against the bottom surface of the recess, and an excessive bending force acts, which may cause a problem of buckling.

  The present invention has been made in view of the above points, and an object of the present invention is to stably hold the endoscope in the accommodated state, and when removing the main body without damaging the insertion portion or the like. An object of the present invention is to provide an endoscope carrying case that allows an operation part to be smoothly taken out.

  In order to achieve the above-mentioned object, the present invention is formed of an elastic member, and forms an attachment part of an endoscope main body operation part, an insertion part, a universal cord, and a housing part of a connector part at the tip thereof, and at least An endoscope carrying case in which a main body housing portion including a concave portion for housing the main body operating portion is formed, the front side of the main body housing portion sandwiching the front and rear positions of the main body operating portion. Each of the elastic holding walls on the rear side, and a finger insertion part for taking out the main body operation part held between the elastic holding walls, and when removing the main body operation part from the main body accommodating part, It is characterized in that the main body operating unit is provided with a priority detachment structure part so that the main body operation part of the both elastic clamping walls comes out first from the front side elastic clamping wall.

  The elastic clamping wall provided in the main body accommodating portion made of a concave portion holds the main body operating portion made of a long member at two places in the front and rear, so that the main body operating portion is stably held in the accommodated state, and vibration acts. To prevent or suppress this. Therefore, if the front elastic clamping wall of the two elastic clamping walls always comes out first, the base part connected to the main body operation part of the insertion part is pressed against the bottom surface of the storage part when taking out. It will never be done. By providing the priority detachment structure portion, the front side elastic clamping wall is made to come out earlier than the rear side elastic clamping wall.

  The preferential detachment structure portion can be formed by changing the structure of the main body housing portion without adding a special member. That is, the finger insertion part provided for taking out the main body operation part is set at a position close to the front elastic holding wall, more preferably at a very close position. Moreover, you may make the direction of the clamping force with respect to the main body operation part by a rear side elastic clamping wall larger than both front elastic clamping walls among both elastic clamping walls. As a result, in the main body operation unit, the connection side to the insertion unit is first lifted from the housing unit.

  The priority detachment structure portion can also be formed by providing a detachment operation member at a site on the connection side with the insertion portion of the main body operation portion. That is, in the main body operation unit, a member that pushes up or pulls up is attached so that the holding portion by the front side elastic holding wall comes out before the rear side elastic holding wall.

  In this way, the main body operation unit is sandwiched between the two elastic clamping walls at the front and rear, and the preferential separation structure is provided so that the front elastic clamping wall comes out first of these elastic clamping walls. Thus, when the main body operation part is taken out from the carrying case housing part, the main body operation part is always taken out first from the portion where the insertion part is connected, and the connection part between the main body operation part and the insertion part can be effectively protected.

    Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, as shown in FIG. 1, the carrying case 1 includes a case body 2 and a lid 3, and the case body 2 and the lid 3 are flexible connecting cloths. The pieces 4 are connected to each other so as to be openable and closable. Further, in the case main body 2 and the lid 3, handbags 5 are respectively attached to portions on the side opposite to the connecting portions by the connecting cloth pieces 4. Here, the case main body 2 and the lid 3 are made of a foamed resin such as a foamed urethane resin in order to reduce the weight, provide buffering properties, and provide elasticity.

  FIG. 2 shows the configuration of the case body 2. The endoscope 10 accommodated in the case main body 2 shown in the figure is provided by connecting an insertion portion 12 to a main body operation portion 11, and the insertion portion 12 is a flexible structure except for a predetermined length of the tip portion. It has become. A taper-shaped cover rubber 12a is attached to the connecting portion of the insertion portion 12 to the main body operation portion 11. Further, a universal cord 13 is drawn out from the main body operation unit 11, and a cover rubber 13 a is also provided at a connection portion of the universal cord 13 to the main body operation unit 11. The universal cord 13 becomes a branching portion 14 on the way, and branches from the branching portion 14 to a light guide cord 15 provided with a light source connector 15a at the tip and an electric cord 16 provided with an electrical connector 16a at the tip. .

  The case main body 2 that accommodates the endoscope 10 having the above configuration accommodates the main body accommodating portion 20 that accommodates the main body operating portion 11, the insertion portion accommodating groove 21 that accommodates the insertion portion 12, and the universal cord 13. And a cord receiving groove 22 to be configured. The cord housing groove 22 is formed of a loop-shaped groove, and first and second connector housing portions 23 and 24 are provided at the tip of the cord housing groove 22. The light source connector 15a is accommodated in the second connector accommodating portion 24, and the electrical connector 16a is accommodated therein.

  FIG. 3 shows an enlarged view of the main body housing portion 20. As is apparent from this figure, the main body accommodating portion 20 is composed of a recess having a size and depth for accommodating the main body operating portion 11 so as to be dropped, and on the tip side thereof, that is, in the vicinity of the connecting portion to the insertion portion 12, The width of the wall portion constituting the concave portion is narrow, and this portion is narrower than the width dimension of the main body operation portion 11 as the front side holding walls 30 and 30. Further, rear side clamping walls 31, 31 narrower than the width of the insertion portion 12 are also formed on the rear side of the main body housing portion 20, that is, in the vicinity of the portion where the universal cord 13 of the main body operation portion 11 is drawn. ing. And the intermediate part of these front side clamping walls 30 and 30 and the rear side clamping walls 31 and 31 is sufficiently wider than the width dimension of the main body operation part 11, and this part is for taking out the main body operation part 11. Finger insertion portions 32 and 32 are provided.

  By configuring as described above, the main body operation unit 11 is accommodated in the main body accommodation unit 20 so as to forcibly expand the holding walls 30 and 31 on the front side and the rear side. Accordingly, the main body operation unit 11 is stably accommodated so as to be sandwiched between the front side clamping walls 30 and 30 and between the rear side clamping walls 31 and 31, and the main body operation unit 11 is contained in the main body accommodation unit 20. There is no undue vibration or misalignment. Further, since the case main body 2 is formed of an elastic member, even if the carrying case 1 vibrates during transportation or collides with other objects, damage or damage may occur. Never do.

  In order to remove the main body operation unit 11 from the main body housing unit 20 of the case main body unit 2, a finger is inserted into the finger insertion units 32 and 32, the main body operation unit 11 is gripped, and lifted upward. The main body operation unit 11 is sandwiched between the front-side sandwiching walls 30 and 30 and between the rear-side sandwiching walls 31 and 31, but the entire case body 2 is formed of an elastic member. , 30 and 31, 31 are forcibly removed and removed.

  Here, in a free state, that is, in a state where the main body operation unit 11 is not accommodated, the distance between the front side holding walls 30 and 30 is D1, the interval between the rear side holding walls 31 and 31 is D2, and the main body operation unit 11 when the width of the portion inserted between the front side holding walls 30 and 30 is B1, and the width of the portion inserted between the rear side holding walls 31 and 31 is B2, (B1-D1) <( B2-D2). That is, when the main body operation unit 11 is housed in the main body housing unit 20, when the holding force by the front side holding walls 30, 30 is compared with the holding force by the rear side holding walls 31, 31, the former is pinched. We weaken power. This is a priority detachment structure, and when the main body operation unit 11 is lifted upward, the front side holding walls 30 and 30 are more easily detached. And after the front side clamping walls 30 and 30 are removed, they are separated from between the rear side clamping walls 31 and 31.

  In addition, when making a difference in the clamping force, as described above, the distance between the clamping walls 30 and 30 and the clamping walls 31 and 31 is not controlled, but the depth of the contact portion in the clamping state. It is also possible to have a difference between the two. For this purpose, a step may be provided so as to shorten the height dimension of the front holding wall 30.

  Therefore, when taking out the main body operation part 11 from the main body accommodating part 20, it will first detach | leave from the front part side clamping wall 30, and the insertion part 12 side will be lifted first. For this reason, the connecting portion between the main body operation portion 11 and the insertion portion 12 is pressed against the bottom surface of the main body housing portion 20, and an unreasonable force acts on the vicinity of the connection portion of the insertion portion 12 to the main body operation portion 11. Absent. That is, when the main body operation section 11 is taken out from the case main body section 2, the vicinity of the connecting section between the main body operation section 11 and the insertion section 12 is not bent and buckled or damaged.

  Next, FIG. 4 shows a second configuration of the priority departure structure. In the configuration of FIG. 4, in the main body housing portion 20, the first embodiment described above in relation to the dimensional relationship between the main body operation unit 11 and the front side holding walls 30 and 30 and between the rear side holding walls 31 and 31. The difference between the position of the finger insertion sections 132 and 132 may be the front side of the position shown in FIG. That is, it is formed at a position close to the front clamping walls 30 and 30.

  With the configuration described above, when a finger is inserted into the finger insertion portions 132 and 132 and the main body operation portion 11 is gripped and lifted, the fingers are sandwiched between the front holding walls 30 and 30 close to the finger insertion portion 132. The lifting force is applied to the part, and the main body operation unit 11 is located farther from the finger insertion unit 132 and is sandwiched by the rear side clamping walls 31 and 31 so that the heavy proximal end side is lowered. It is taken out in a tilted state. Therefore, the connection part with the main body operation part 11 in the insertion part 112 does not bend.

  Further, FIGS. 5 and 6 show a third configuration of the priority separation structure. In this embodiment, the priority detachment structure portion is formed by a pulling ribbon 40 as a detachment operation member disposed so as to wrap around the main body operation portion 11 at or near the front-side clamping walls 30, 30. Is configured. The pull-up ribbon 40 is fixedly provided on one front side holding wall 30 or the upper surface of the case main body 2 and is made to wrap around the lower side of the main body operation unit 11 attached to the main body accommodating unit 20. . Then, the other end of the pulling ribbon 40 extends from the front side holding wall 30 to an upper position.

  With this configuration, when the main body operation unit 11 is mounted in the main body housing unit 20 of the case main body unit 2, as shown in FIG. Insert into. Then, as shown in FIG. 6, when the pulling ribbon 40 that is a free end is operated to be pulled upward, the tip side portion of the main body operation unit 11 can be easily moved from between the front side holding walls 30 and 30. At this time, since a special pulling force does not act on the portion sandwiched between the rear side sandwiching walls 31, 31, the clamping force at this portion is not lost. As a result, when the main body operation unit 11 is taken out from the main body housing unit 20, the main body operation unit 11 first comes out of the connection side to the insertion unit 12.

  Further, FIGS. 7 to 9 show a fourth configuration of the priority separation structure. In other words, a drop portion 41 is formed on the bottom surface of the main body housing portion 20 at a site where the finger insertion portion 21 is provided. The drop portion 41 is provided with a pair of left and right elastic columns 42, 42. The elastic column 42 is disposed at the same height as the bottom surface of the main body housing portion 20, and a lift plate 43 is fixedly provided at the tip thereof. The lift plate 43 is disposed on the lower surface portion of the main body accommodating portion 20 where the main body operating portion 11 is accommodated, and at the portion of the finger insertion portion 32, the upper portion of the mounting portion of both elastic columns 42, 42. The positions are provided with operation overhang portions 43a and 43a. The lift plate 43 projects from the operation projecting portion 43a toward the connecting portion to the insertion portion 12 of the main body operation unit 11 by a predetermined length.

  In order to house the endoscope 1 in the case body 2, when the body operation unit 11 is attached to the body housing 20, the lift plate 43 is disposed as an underlay as shown in FIGS. 7 and 8. To do. And when taking out the endoscope 1, the part exposed to the site | part of the finger insertion part 32 among the lift plates 43 is pushed down. As a result, the elastic column 42 is compressed, and the lift plate 43 tilts with the edge portion of the drop-in portion 41 as a fulcrum so that the portion supported by the elastic column 42 is downward. As a result, as shown in FIG. 9, it is lifted by the lift plate 43 and can be taken out so that the connection side to the insertion portion 12 in the main body operation portion 11 rises.
