  Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

  This embodiment is a large intestine endoscopy auxiliary tool for assisting an operation of performing an inspection by inserting a large intestine endoscope into the intestinal tract. While this colonoscopy aid is extremely simple and inexpensive, it can easily be inserted into the intestine without any pain to the patient, and The remaining excess air and intestinal tract washing liquid can be efficiently discharged outside the body.

  First, a detailed description will be given of an auxiliary instrument for colonoscopy shown as the first embodiment. The large intestine endoscopy auxiliary tool discharges air or intestinal rinsing fluid that has accumulated in the intestinal tract by perforating a plurality of holes in a flexible tube material.

  As shown in FIG. 1, a large intestine endoscopy auxiliary tool 10 includes one tube material 11, a solid member 12 fixed in a partial region of the tube material 11, and an inside of the tube material 11. It is comprised from the spring material 13 inserted.

  The tube material 11 is made of a predetermined material that is harmless to the human body, such as a silicon tube, and has an inner diameter of, for example, about 2 mm to 3 mm. The tube material 11 has flexibility and can be bent freely. In addition, a plurality of holes 14 are drilled in the tube material 11 in a region extending from one end forming an insertion port to be inserted into the intestinal tract from the patient's anus into the intestinal tract, for example, a predetermined length of about 5 cm. It is installed. As will be described later, the hole 14 functions as an intake for taking in fluid such as excess air remaining in the intestinal tract of the patient and intestinal irrigation fluid. Further, the tube material 11 has a plurality of holes 15 extending over an internal cavity over a predetermined length of about 5 cm, for example, in a region separated by a predetermined length from the region where these holes 14 are formed toward the other end. It has been drilled. As will be described later, the hole 15 functions as a discharge port for discharging fluid, such as air and intestinal tract washing liquid, taken into the tube material 11 from the hole 14 to the outside.

  The solid member 12 is made of a predetermined material harmless to the human body having an outer diameter of, for example, about 15 mm, and is fixed to a partial region of the tube material 11 by being inserted through the tube material 11 as shown in FIG. Is done. Specifically, the solid member 12 is fixed downstream of the region of the tube material 11 where the hole 14 is formed. The solid member 12 is provided so that the tube material 11 inserted from the patient's anus into the rectum does not easily come out of the rectum. Therefore, it is desirable that the solid member 12 is provided in the immediate vicinity of the region where the hole 14 is inserted into the patient's rectum and functions as an intake port for air and intestinal lavage fluid. The solid member 12 is preferably formed as a sphere in order to prevent damage to the patient's rectal mucosa and large intestine endoscope.

  The spring material 13 is made of, for example, a metal or resin coil spring or the like, and is inserted so as to be fitted into the tube material 11. Specifically, the spring member 13 is inserted between a region of the tube member 11 where the solid member 12 is fixed and a region where the hole 15 is formed. The region in the tube material 11 in which the spring material 13 is inserted can be freely bent by the flexibility of the spring material 13 and the flexibility of the tube material 11 itself. The presence of the material 13 is prevented from being crushed.

  Such an auxiliary instrument 10 for colonoscopy is used as shown in FIG. 3, for example.

  That is, the colonoscopy aid 10 together with the colonoscope 20 is inserted into the rectum RC from the anus to the patient. At this time, at least the region of the tube material 11 in which the hole 14 is formed and the region in which the solid member 12 is fixed are inserted into the patient's rectal RC. In the colonoscopy aid 10, the tube material 11 exposed outside the body is fixed to the patient's body, for example, by sticking with a predetermined fixing tape 21 along the lower limbs of the patient. Is done. In the colonoscopy aid 10, the outer diameter of the solid member 12 that is significantly smaller than the outer diameter of the normal colonoscope 20 is the thickest part. It will not cause any damage.

  The auxiliary instrument 10 for large intestine endoscopy used in this way allows excess air or intestinal irrigation fluid staying in the large intestine or rectum RC of the patient to pass through the hole 14 when the large intestine endoscope 20 is operated. Into the tube material 11 and discharged from the hole 15. Thereby, in the large intestine endoscopy auxiliary tool 10, the situation where a patient's large intestine intestine extends too much can be prevented, and insertion of the large intestine endoscope 20 can be facilitated. Further, in the colonoscopy assisting tool 10, when the colonoscope 20 is allowed to reach the cecum of the patient and the intestinal tract is expanded to fully observe the inside of the large intestine, the hole 15 is formed. Clamping the upstream side of the perforated region with the forceps 22 or the like can also stop the discharge of air and intestinal tract washing liquid. In this manner, the colonoscopy aid 10 can control the amount of air and intestinal lavage fluid in the intestinal tract of the patient as necessary.

  Here, in the large intestine endoscopy auxiliary tool 10, since a plurality of holes 14 and 15 are provided, air and intestinal tract washing liquid can be efficiently used even though the inner diameter of the tube material 11 is small. Can be taken in and discharged out of the body.

  Moreover, since the tube material 11 has flexibility including the area | region in the tube material 11 in which the spring material 13 was inserted as mentioned above, it can be freely bent according to a patient's body shape. Therefore, in the large intestine endoscopy aid 10, the presence of the tube material 11 does not hinder the operation of the large intestine endoscope 20, and there is less irritation to the anus without damaging the rectal mucosa. Air and intestinal lavage fluid can be discharged outside the body.

  Further, in the colonoscopy aid 10, the solid member 12 inserted into the patient's rectum RC is caught by the anal sphincter SP, so that the colonoscopy 20 is moved in the front-rear direction in the rectum RC. Even when the tube material 11 is rotated or rotated, it is possible to reliably prevent the tube material 11 inserted into the rectum RC from being removed from the rectum RC. Further, the solid member 12 is formed as a sphere to prevent the risk of damaging the rectal mucosa and the large intestine endoscope 20 by contacting with the inner wall of the rectal RC and the large intestine endoscope 20 as described above. Can do.

  Furthermore, in the large intestine endoscopy auxiliary tool 10, since the spring material 13 is inserted into the tube material 11, the tube material 11 is sandwiched between the patient's anal sphincter SP and the large intestine endoscope 20. It can be surely prevented from being crushed. In addition, in the colonoscopy assisting instrument 10, as described above, the spring material 13 and the tube material 11 are used in combination, so that free bending that cannot be achieved with a simple metal tube or the like is realized. Therefore, the shape formed by the anal sphincter muscle SP and the large-intestine endoscope 20 can be handled smoothly, and the operation of the large-intestine endoscope 20 is not hindered.

  In addition, the colonoscopy assisting instrument 10 can be configured very simply and at a low cost, and is therefore suitable for disposable use. Accordingly, the colonoscopy aid 10 does not need to be cleaned after use, and does not cause an infection, and has an excellent effect from the viewpoint of hygiene.

  In this way, the colonoscopy aid 10 can contribute to a test that significantly reduces the burden on the patient, and can be used for normal examinations or for treatments such as polypectomy that require more time. Of course, in the case where it is necessary to insert the colonoscope 20 once after it has been inserted into the intestinal tract of the patient, or another examiner can insert the colonoscope 20. It is also extremely effective when it is removed once and then inserted again.

  In addition, as shown in FIG. 4, the large intestine endoscopy auxiliary tool 10 may be one in which, for example, a plurality of holes 16 are formed in the solid member 12. The hole 16 is formed from the surface of the solid member 12 to the tube material 11. That is, by taking in air and intestinal tract washing liquid from the hole 14 and taking in air and intestinal tract washing liquid from the hole 16 formed in the solid member 12, the air and intestinal tract washing liquid can be taken in more efficiently.

  Hereinafter, the second embodiment will be described in detail.

  The second embodiment is a large intestine endoscopy auxiliary tool for assisting in an operation of performing an inspection by inserting a large intestine endoscope into the intestinal tract, and the first embodiment described above. Although the configuration is different from the above-described large intestine endoscopy auxiliary tool, the details thereof will be described. In addition, since the usage method etc. are the same as the auxiliary tool for colonoscopy mentioned above, detailed description is abbreviate | omitted.

  Specifically, in the colonoscopy device 10 in the first embodiment, the solid member 12 is fixed on the downstream side of the region of the tube material 11 where the hole 14 is formed. In the second embodiment, a solid member having a hole formed on the surface thereof is fixed to the end of the tube material, and the hole formed in the solid member communicates with a cavity inside the tube material. There is a difference in point.

  As shown in FIG. 5, the colonoscopy auxiliary tool 30 includes one tube member 31, a solid member 32 fixed to the tip of the tube member 31, and the tube member 31. It is comprised from the spring member 13 made.

  The tube material 31 is made of a predetermined material that is harmless to the human body, such as a silicon tube, and has an inner diameter of, for example, about 2 mm to 3 mm. The tube material 31 has flexibility and can be bent freely. The tube member 31 is provided with a solid member 32 at one end inserted from the patient's anus into the intestinal tract. Further, the tube material 31 has a plurality of holes 35 extending over an internal cavity over a predetermined length of about 5 cm, for example, in a region separated by a predetermined length from the region where the solid member 32 is formed toward the other end. It has been drilled. As will be described later, the hole 35 functions as a discharge port for discharging a fluid such as air or intestinal tract cleaning liquid taken into the tube member 31 from a hole formed in the solid member 32 to the outside.

  The solid member 32 is made of a predetermined material harmless to a human body having an outer diameter of, for example, about 15 mm, and is fixed to the tube material 31 as shown in FIG. The solid member 32 is provided so that the tube material 31 inserted from the patient's anus into the rectum does not easily come out of the rectum. The solid member 32 is formed with, for example, a hole drilled up to the inside of the solid member 32 and having substantially the same diameter as that of the tube material 31. By inserting the tube material 31 into the hole, The solid member 32 is fixed. Furthermore, a hole 36 is formed in the surface of the solid member 32 so as to function as an intake port for taking in the fluid staying in the intestinal tract of the patient. In the present embodiment, the solid member 32 is described in detail as having a plurality of holes 36, but the solid member 32 may have one hole 36. The hole 36 is formed so as to communicate from the surface of the solid member 32 to one end of the tube material 31. Specifically, one end of the hole 36 is formed on the surface of the solid member 32, and the other end of the hole 36 is formed so as to be connected to the tube material 31. The solid member 32 is preferably formed as a sphere in order to prevent damage to the patient's rectal mucosa and large intestine endoscope.

  That is, excess air or intestinal rinsing liquid staying in the intestinal tract flowing in from one end of the hole 36 can flow out from the other end of the hole 36 to the tube member 31 through the inside of the hole 36.

  Such a colonoscopy auxiliary tool 30 can obtain the same effects as those described in the first embodiment, and from the colonoscopy auxiliary tool 10 of the first embodiment. Since the tube material is shortened, the possibility of damaging the rectal mucosa of the patient can be reduced.

  As shown in FIG. 7, the opening area of one end formed on the surface of the solid member 32 may be larger than the opening area of the other end of the hole 36. That is, by making the opening area of one end formed on the surface of the solid member 32 of the hole 36 larger than the opening area of the other end of the hole 36, the hole 36 forms a so-called nozzle shape, and thereby, in the intestinal tract of the patient. It is possible to easily take in excess air and intestinal tract washing liquid that has stayed, and to prevent backflow of the staying material once taken into the holes.

  The present invention is not limited to the embodiment described above. For example, in the above-described embodiment, only the normal tubes having cavities are mentioned as the tube materials 11 and 31, but the present invention reduces friction caused by contact with the colonoscope. A predetermined coating may be applied to the outer surfaces of the tube members 11 and 31.

  Further, in the present invention, the shape of one end forming the insertion port in the tube material 11 inserted from the patient's anus into the intestinal tract is, for example, formed obliquely as shown in FIG. As shown in FIG. 9, insertion into the rectal RC can be facilitated by using a closed end having a predetermined curvature.

  Furthermore, the present invention can apply shapes other than the sphere as the shapes of the solid members 12 and 32. However, as described above, the solid members 12 and 32 are preferably those whose outer surfaces are formed in a predetermined curved shape from the viewpoint of preventing damage to the rectal mucosa and the colonoscope 20 of the patient. For example, in addition to the sphere shown in FIG. 10 (a), a shape similar to the sphere is desirable. In addition, as a shape body according to the sphere, for example, an ellipsoid as shown in FIG. 10B or a surface in contact with the large-intestine endoscope 20 as shown in FIG. And a bowl-shaped body formed in a bowl shape along the curvature. In particular, the solid members 12 and 32 can be made in the form of rods to increase the contact area with the colonoscope 20 and to prevent unnecessary movement in the patient's rectal RC. it can. The present invention also makes it easy to insert the rectal RC into the rectal RC by applying a predetermined coating on the outer surface of the solid members 12 and 32, and ensures damage to the rectal mucosa and the colonoscope. You may make it aim at prevention.
