Description

[Detailed Description of the Invention] This invention relates to an endoscope carrying case for storing and transporting an endoscope.

Generally, a carrying case is used to protect the endoscope from vibrations and shocks applied during transportation.

By the way, this type of carrying case has conventionally been equipped with a cushioning material such as a sponge inside the case body, and this cushioning material has a curved insertion groove for housing the operating section of the endoscope, the flexible tube, and the curved section. A curved insertion groove for accommodating a light guide conduit tube (universal cord) formed by inserting a light guide connected to the operating section is formed, and at least a portion of each insertion groove is connected to the flexible tube and A configuration in which the flexible tube and the light guide conduit are securely held by making the tube narrower than the outer diameter of the light guide conduit has been considered.

However, with such a configuration, if you store an endoscope whose size deviates from the standard dimensions of the carrying case, the outer diameter of the flexible tube or light guide conduit may become larger than the standard dimensions. When storing endoscopes with different diameters, it is difficult to insert the endoscope's flexible tube and light guide conduit into the respective insertion grooves, so when the user takes the endoscope in and out of the carrying case, the flexible tube There was a risk of damaging the light guide conduit. Furthermore, when using a flexible tube or light guide conduit whose outer diameter is smaller than the standard dimensions of the carrying case, it is easy to move the endoscope in and out of the carrying case. However, the flexible tube and light guide conduit cannot be held securely, and the flexible tube, curved portion, and light guide conduit are likely to vibrate within each insertion groove due to vibrations and shocks applied during transportation. There was a risk that various parts of the endoscope would be worn out and damaged by sliding on the cushioning material. Therefore, a single carrying case cannot accommodate endoscopes whose flexible tubes or light guide conduit outer diameters deviate from the standard dimensions, and A special carrying case or a cushioning material for the carrying case had to be prepared for each case, which resulted in a problem that increased costs.

In addition, after attaching a holding block made of a cushioning material and having a clamping groove narrower than the outer diameter of the endoscope's flexible tube and light guide conduit tube to appropriate locations in each insertion groove of the case body. It is also conceivable to have a structure in which the flexible tube and light guide conduit tube are pushed into the clamping groove, and to provide a variety of holding blocks with different width dimensions of the clamping groove to standardize the carrying case. With such a structure, there is a risk of losing the holding block, and if the holding block is lost, there is a problem that the endoscope may be damaged.

This idea was made in consideration of the above circumstances, and its purpose was to make it easy to take in and take out the endoscope, to reliably prevent wear on each part of the endoscope during transportation, and to make the flexible tube and light guide conduit tube An object of the present invention is to provide an endoscope carrying case that can commonly accommodate many types of endoscopes having different outer diameters.

An embodiment of this invention will be described below with reference to the drawings. FIG. 1 shows the overall structure of a carrying case for an endoscope, where 1 is a case body and 2 is a cover hinged to the case body 1. As shown in FIG. A handle 3 is provided on the case main body 1 so that the case body 1 can be carried. Further, a cushioning material 4 such as a sponge is attached inside the case body 1, and the upper surface of this cushioning material 4 is substantially flush with the opening edge of the case body 1. On the upper surface of this cushioning material 4, there is a curved insertion groove 9 into which the operating section 6, flexible tube 7, and curved section 8 of the endoscope 5 are inserted, and a curved insertion groove 9 into which the light guide conduit 10 connected to the operating section 6 is inserted. An insertion groove 11 is provided. Furthermore, a recess shallower (smaller in depth) than the depth L of the insertion groove 9 is provided at an appropriate location of the insertion groove 9, that is, a portion where the middle part of the flexible tube 7 and the middle part of the curved part 8 are inserted. The parts 12, 12 are arranged in series. In this case, as shown in FIG. 2, the height l from the groove bottom 9a of the insertion groove 9 to the bottom surface 12a of each recess 12 is set to be smaller than the outer diameter A of the thinnest flexible tube 7. There is. Further, each of the recessed portions 1
A pair of protrusions 13, 13 are provided integrally with the cushioning material 4 on the side wall of the lower insertion groove 9. A clamping groove 14 having a width narrower than the outer diameter of the flexible tube 7 and the curved portion 8 is formed between the two protrusions 13, 13.

On the other hand, inside the cover 2, a cushioning material 15 made of sponge or the like is attached. This buffer material 1
A cushioning material 15 is provided on the top surface of 5 at a portion facing each of the recessed portions 12 when the cover 2 is fitted onto the case body 1 (when the carrying case is closed).
Fitting protrusions 16, 16 are integrally provided with the fitting protrusions.
These fitting protrusions 16, 16 fit loosely into the recesses 12, 12 when the cover 2 is fitted onto the case body 1, and the bottom surfaces 12a, 1 of the recesses 12, 12.
It is formed with a height dimension that is sufficient to press 2a.

Therefore, when storing the endoscope 5 in the endoscope carrying case configured as described above, first
The flexible tube 7 and the curved portion 8 are pushed in along the insertion groove 9 in the case body 1, and the light guide conduit tube 10 is similarly pushed in along the insertion groove 11. In this manner, when the endoscope 5 is mounted within the cushioning material 4 of the case body 1, the upper ends of the flexible tube 7 and the curved portion 8 protrude into the recessed portions 12, 12, as shown in FIG. ing. Therefore, next, case body 1
When the cover 2 is fitted into the recessed portions 12, 12, the upper ends of the flexible tube 7 and the curved portion 8 are inserted into the fitting convex portions 16, 16 that are loosely fitted into the recessed portions 12, 12, and the flexible tube 7 and The curved portion 8 is firmly held between the fitting convex portions 16 and the groove bottom 9a of the insertion groove 9. Therefore, by fitting the cover 2 onto the case body 1, the flexible tube 7 and the curved portion 8 in the insertion groove 9 can be held down, and the endoscope 5 can be held securely even when subjected to vibrations, shocks, etc. when carried. The flexible tube 7 and the curved portion 8 do not vibrate within the insertion groove 9, and do not slide against the cushioning materials 4, 15 and wear out. Moreover, after the flexible tube 7 and the curved part 8 are installed in the cushioning material 4 on the side of the case body 1, the fitting protrusions 16, 16 provided on the cushioning material 15 on the cover 2 side and the groove bottom of the insertion groove 9 are inserted. 9a, the insertion groove 9 can be formed relatively loosely with respect to the flexible tube 7 and the curved portion 8. Therefore, the endoscope 5 can be easily taken in and out of the case body 1. Furthermore, since the outer diameter of the flexible tube 7, etc. of the endoscope 5 housed in the case 1 is not limited by the width of the insertion groove 9, Many types of endoscopes with different outer diameters, such as the flexible tube 7, can be commonly stored.
Cost reduction can be achieved.

Although the above embodiment shows a configuration in which the flexible tube 7 and curved portion 8 of the endoscope 5 are held down, a configuration in which the light guide conduit tube 10 is also held may be used. Furthermore, it goes without saying that various other modifications can be made without departing from the gist of the invention.

As explained above, in this invention, at least a part of the insertion groove into which the flexible tube is inserted and the insertion groove into which the light guide conduit tube is inserted is provided with a concave portion, and the cover fitted onto the case body is provided with the recessed portion. A fitting protrusion is provided which fits into the recess and holds the flexible tube and light guide conduit of the endoscope.
Therefore, the flexible tube and the light guide conduit can be securely held between the fitting protrusion that fits into the recess and the groove bottom of the insertion groove, thereby preventing vibrations, shocks, etc. when transporting the endoscope. The endoscope does not vibrate within the insertion groove even if the force is applied to the endoscope, and wear of various parts of the endoscope can be reliably prevented. Further, since the insertion groove can be formed relatively loosely with respect to the flexible tube and light guide conduit of the endoscope, the endoscope can be easily inserted and removed. Furthermore, since the width of the flexible tube and light guide conduit of the endoscope to be stored is not limited by the width of the insertion groove, the outer diameter of the flexible tube and light guide conduit can be reduced. Many different types of endoscopes can be commonly stored.
