Description

  The present invention relates to a non-reusable plug that is attached to an attachment portion of an endoscope, and an endoscope including the plug.

  Conventionally, in the medical field, an insertion portion of an endoscope is inserted into a patient's body, and various treatments are performed on the affected area in addition to observing the affected area (see Patent Document 1). Specifically, various treatment tools such as forceps and an incision tool are inserted into a treatment tool insertion channel in the insertion portion from a treatment tool introduction portion (mouth portion) provided in the operation portion of the endoscope, and the distal end of the insertion portion By projecting from the head, various treatments such as observation, excision, and sampling of the affected area are performed.

  A treatment instrument plug through which the treatment instrument can be inserted is attached to the treatment instrument introduction section (see Patent Documents 2 to 4). This treatment instrument stopper prevents body fluid, dirt, air, and the like in the body from flowing back through the treatment instrument insertion channel due to a change in the internal pressure of the body and leaking out from the treatment instrument introduction portion. For this reason, a bodily fluid etc. adhere to a treatment implement stopper by use. As a treatment tool stopper, a disposable type that is not reusable is generally used so that it is replaced with a new one for each use from the viewpoint of preventing infection.

  Patent Documents 2 to 4 disclose treatment instrument plugs that can be detached from the treatment instrument introduction section by breaking a part of the plug body. These treatment tool stoppers are not reusable because they are broken when removed from the treatment tool introduction portion. As a result, the used treatment instrument stopper is prevented from being reused by mistake.

  Patent Document 5 discloses an endoscope apparatus that prevents reuse of a disposable endoscope cover. In this endoscope apparatus, ID information is read from an ID tag provided on an endoscope cover by a tag reader provided on the endoscope, and the read results are sequentially stored in an electronic medical record server. Then, by comparing the ID information newly read by the tag reader with the ID information stored in the electronic medical record server, it is determined whether or not the endoscope cover has been used. A warning is displayed. Therefore, in the thing of this patent document 5, reuse of a treatment tool stopper can be prevented by providing an ID tag in a treatment tool stopper.

  Since the forceps plugs of Patent Documents 2 to 4 are broken when they are removed from the treatment instrument introducing portion, there is a possibility that debris generated by the destruction may enter the treatment instrument insertion channel. In this case, there is a possibility that the cleaning / disinfection processing in the treatment instrument insertion channel may be hindered. Further, in the treatment instrument plugs of Patent Documents 2 to 4, it is necessary to form a weak portion such as a cut so that the treatment tool plug is easily broken when detached from the endoscope. For this reason, when attaching a treatment tool stopper to a treatment tool introducing | transducing part, or at the time of endoscopy, there exists a possibility of destroying a weak part accidentally.

  In Patent Document 5, an ID tag is provided on the treatment instrument stopper, and whether or not the treatment instrument stopper is reused is determined based on the unique identification information read from the ID tag, so that it is not necessary to destroy the treatment instrument stopper. . However, it is necessary to provide an ID tag on the treatment instrument stopper and a tag reader on the endoscope. Further, a circuit for comparing the ID information read by the tag reader with the ID information stored in the electronic medical record server is required. As a result, the manufacturing cost increases.

  The present invention has been made to solve the above problems, and provides a plug for an endoscope that cannot be reused without being destroyed, and an endoscope including the plug, at a low cost. The purpose is to do.

  In order to achieve the above object, an endoscope plug body of the present invention is an endoscope plug body attached to an attachment portion of an endoscope, and includes a cylindrical plug body made of an elastic material, Formed on the plug body, fits into the mounting section and prevents the plug body from moving in the insertion / removal direction from the mounting section, and built in the plug body, allowing the mounting / receiving section to move in the insertion / removal direction It includes a pre-curing state and a curing portion having a time-curing property that is irreversibly cured to a post-curing state that restricts movement of the attachment receiving portion in the insertion / removal direction.

  The attachment portion is a substantially cylindrical base that communicates with a treatment instrument insertion channel in the endoscope, and the plug has a treatment instrument insertion hole through which the treatment instrument is inserted, and a base receiving portion that fits into the base. It is desirable to have it as a mounting receiving part.

  The base has a base fitting part at the outer end, and the base fitting part has a base-side annular projecting part projecting outward from the outer peripheral surface and a base-side circumferential groove formed on the outer peripheral surface. . The base receiving part is formed on the inner peripheral surface of the stopper main body, and is formed on the stopper main body side circumferential groove that fits into the base side annular projecting part, and the inner peripheral surface of the stopper main body, and is fitted in the base side circumferential groove. It is desirable to have a plug body-side annular protrusion.

  The curing portion has a cylindrical curing portion main body disposed on the stopper main body, and an insertion / removal-restricted annular protrusion protruding from the hardening portion main body toward the stopper body-side annular protrusion. It is desirable that the inner diameter of the insertion / removal restriction annular projection is smaller than the outer diameter of the projection.

  It is desirable that the plug body has light permeability, and the curing portion has photocurability that cures upon irradiation with light transmitted through the plug body. The stopper main body is housed in a light-shielding package, and it is desirable that the plug body is taken out from the package and used in a base when used.

  It is desirable that the curing portion be in a post-curing state that restricts the movement of the attachment receiving portion in the insertion / removal direction after elapse of the treatment time by the endoscope.

  The plug body desirably includes a valve member that closes the treatment instrument insertion hole from the outside, a connecting member that connects the valve member to the plug body, and a valve member receiving portion into which the valve member is fitted.

  The endoscope of the present invention includes an insertion portion that is inserted into the body, an operation portion that is connected to the proximal end of the insertion portion, an attachment portion that is provided on the outer surface of the operation portion and that leads to a channel that passes through the insertion portion. And the plug body mounted on the mounting portion.

  According to the present invention, a hardened portion having aging property is provided in a cylindrical plug body made of an elastic material, and the hardened portion is irreversibly cured to move the plug body from the mounting portion in the insertion / removal direction. Therefore, after the cured portion is cured, it is impossible to reattach the plug body to the endoscope. Thereby, reuse of the used stopper is prevented without destroying the stopper. As a result, it is possible to prevent troubles such as debris generated by destruction entering the channel. Further, it is not necessary to form a weak portion such as a cut in the plug body, and the weak portion is not accidentally destroyed when the plug body is attached to the mouth portion. Furthermore, it is possible to prevent the reuse of the plug without destroying it only by improving the plug, thereby reducing the cost.

[First embodiment]
As shown in FIG. 1, an endoscope 10 is a bronchoscope that is inserted into a trachea, for example, and includes an insertion section 11 that is inserted into the trachea, an operation section 12, and a universal cord 13. The operation unit 12 is connected to the proximal end portion of the insertion unit 11. One end of the universal cord 13 is connected to the operation unit 12, and the other end is connected to a processor device, a light source device, and the like (not shown) through a composite type connector 13a.

  The insertion portion 11 is divided into a distal end rigid portion 11a, a bendable bending portion 11b, and a flexible flexible tube portion 11c in order from the distal end side to the proximal end side. The distal end surface of the distal rigid portion 11a is provided with a treatment instrument outlet 15 which is an outlet of the treatment instrument 14 such as forceps, and an imaging window and an illumination window (not shown). An image sensor (not shown) or the like is disposed behind the imaging window, and an optical fiber cable (not illustrated) is disposed behind the illumination window. A signal line and an optical fiber cable of the image sensor pass through the insertion portion 11, the universal cord 13, and the connector 13a and are connected to the processor device and the light source device, respectively.

  A treatment instrument insertion channel 16 for inserting the treatment instrument 14 is disposed in the insertion portion 11. One end of the treatment instrument insertion channel 16 is connected to the treatment instrument outlet 15, and the other end is connected to a treatment instrument introduction section 17 provided in the operation section 12. The treatment instrument insertion channel 16 is also used as a path for sucking body fluid such as blood and solid matter such as filth from the treatment instrument outlet 15. A suction channel (not shown) branched from the treatment instrument insertion channel 16 is disposed in the operation unit 12, and this suction channel is connected to a suction button 18 provided in the operation unit 12.

  The suction button 18 is connected to a negative pressure source (not shown) outside the operation unit 12. The suction button 18 switches communication / blocking between the suction channel and the negative pressure source by a pressing operation or release of the pressing operation.

  As shown in FIGS. 2 to 4, the treatment instrument introduction portion 17 is provided with a base 20 corresponding to the attachment portion of the present invention. A disposable treatment tool stopper (plug body) 21 into which the treatment tool 14 can be inserted is attached to the base 20. The treatment instrument plug 21 prevents bodily fluids, dirt, air, and the like in the body from flowing back through the treatment instrument insertion channel 16 and leaking from the base 20 to the outside when performing treatment with the treatment instrument 14.

  The base 20 has an internal conduit 23 that leads to the treatment instrument insertion channel 16. The base 20 has a base body 20a fixed inside the opening 17a of the treatment instrument introduction part 17, and a base front end 20b protruding to the near side of the opening 17a. A packing 24 is fitted on the outer peripheral surface of the base body 20a. The packing 24 prevents body fluid and the like from leaking from the gap between the treatment instrument introducing portion 17 and the inner peripheral surface. Hereinafter, the front side direction of the opening 17a is simply referred to as “front side direction”, and the back direction of the base 20 opposite to the front direction is simply referred to as “back direction”. Also, the front side end and end surface of each part of the base 20 and the treatment instrument plug 21 are referred to as a front end part and a front end face, respectively, and the end part and end face on the back side of each part are referred to as a back end part and a back end face, respectively.

  The base end portion 20b has an outer diameter that is slightly smaller than the outer diameter of the base body portion 20a, and forms a base side circumferential groove. A flange 25 that engages with the treatment instrument stopper 21 is formed at the tip of the base tip 20b. The flange 25 functions as a base-side annular protrusion. A base fitting portion is constituted by the base side circumferential groove and the base side annular projecting portion.

  The treatment instrument plug 21 includes a substantially cylindrical plug main body 29 and a substantially cylindrical light curing portion 31 provided on the plug main body 29. The plug body 29 is formed of an elastic material having light transmittance such as transparent rubber. The plug main body 29 has a cap insertion hole 29a opened at its back end and a cap mounting hole 29b opened at its front end.

  The base insertion hole 29 a and the cap attachment hole 29 b are partitioned by a partition wall 33 provided inside the stopper body 29. A small hole 33a for inserting the treatment instrument 14 is formed in the partition wall 33. The small hole 33 a is formed with a smaller diameter than the outer diameter of the treatment instrument 14.

  An annular engaging claw 35 that engages with the flange 25 is formed along the circumferential direction of the inner wall surface of the plug body 29 along the circumferential direction. The engaging claw 35 functions as a plug-side annular projecting portion. The inner diameter of the engaging claw 35 is formed to be equal to or larger than the outer diameter of the base end portion 20 b and smaller than the outer diameter of the flange 25. The base insertion hole 29a functions as a plug main body side circumferential groove that fits into the flange 25 that is the base side annular projection. A cap receiving portion as an attachment receiving portion is configured by the plug-side annular projecting portion and the plug body-side circumferential groove. The plug body 29 is attached to the base 20 by fitting the base receiving part and the base fitting part.

  A cap 39 is integrally provided on the plug body 29 via a connection belt 38. A concave portion 39a is formed on the front end surface of the cap 39 as an entrance of the treatment instrument 14, and a fitting portion 39b that fits into the cap mounting hole 34 is formed on the back end surface. A slit 40 reaching the inside of the cap attachment hole 29b is formed on the bottom surface of the recess 39a.

  When the treatment instrument 14 is not inserted, the slit 40 is brought into a close contact state by the elastic force of the cap 39 and maintains a watertight / airtight state. In addition, the slit 40 is in a state where the inner peripheral surface of the slit is in close contact with the outer peripheral surface of the treatment instrument 14 by the elastic force of the cap 39 in a state where the treatment instrument 14 is inserted, thereby preventing leakage due to backflow of body fluid or the like. . The slit 40 and the small hole 33a are arranged coaxially with the internal conduit 23 when the base end portion 20b is inserted into the base insertion hole 29a. Therefore, the treatment instrument 14 is inserted into the treatment instrument insertion channel 16 through the slit 40, the small hole 33a, and the internal conduit 23.

  The photocuring portion 31 is provided between the outer wall surface and the inner wall surface of the plug body 29. The photocuring unit 31 includes a cylindrical curing unit main body 31a and an insertion / removal restriction annular projection 31b. The insertion / removal restricting annular projecting portion 31 b projects from the inner end of the cured portion main body 31 a toward the engaging claw 35. The inner diameter of the insertion / removal restricting annular protrusion 31b is smaller than the outer diameter of the flange 25, which is the base-side annular protrusion. As a result, when the photocuring portion 31 is cured, the flange 25 gets over the insertion / removal restriction annular protrusion 31b and inserted, and conversely, when the flange 25 is inserted, it does not come out.

  The photocuring portion 31 is formed of a photocuring resin that is cured by being irradiated with light of various wavelengths such as ultraviolet light. The photocuring unit 31 may be in a solid state or a liquid state before the photocuring, and in the former case, it has flexibility. The photocuring portion 31 is integrally formed with the plug body 29 in the solid state, and is injected into the plug body 29 in the liquid state. The photocuring portion 31 regulates elastic deformation of the plug main body 29, particularly diameter expansion deformation of the base insertion hole 29a when photocured.

  As the photo-curing resin forming the photo-curing portion 31, a resin that cures gradually upon irradiation with light and completes curing in a predetermined time is used. The predetermined time here is, for example, longer than the time until one endoscope inspection is completed, but shorter than the time until the endoscope cleaning / disinfection processing after the inspection is completed. Time (several hours). Note that since the examination end time varies depending on the type of endoscopic examination and the type of observation site, the type of the photocurable resin may be changed depending on these types. Further, since the cleaning / disinfecting processing time varies depending on the contents of the cleaning / disinfecting process, the type of the photo-curing resin may be changed according to the processing contents.

  As shown in FIG. 5, the treatment instrument plug 21 is housed in a light-shielding package 42 when shipped from the manufacturer. Thereby, the photocuring part 31 of the unused treatment instrument stopper 21 is prevented from being photocured. The package 42 is sterilized.

  Next, the operation of the treatment instrument stopper 21 having the above-described configuration, particularly the attachment and removal processing of the treatment instrument stopper 21 to the base 20 will be described. First, the treatment instrument stopper 21 is taken out from the package 42. Thereby, since light is irradiated to the photocuring part 31 through the plug main body 29, the photocuring part 31 hardens | cures gradually.

  Next, as shown in FIG. 6, the center of the base insertion hole 29a is positioned with respect to the center of the base end portion 20b, and in this state, a pressing operation for pressing the treatment instrument plug 21 toward the base end portion 20b is started. . Thereby, the base end portion 20b and the flange 25 are inserted into the base insertion hole 29a.

  As shown in FIG. 7, when the inner peripheral surface of the plug main body 29 is pressed by the flange 25, the diameter of the base insertion hole 29 a gradually increases with the insertion of the flange 25. When the pressing operation is continued, the diameter of the base insertion hole 29a is further expanded and the inner diameter of the engagement claw 35 becomes larger than the outer diameter of the flange 25. Thereby, the engaging claw 35 gets over the flange 25.

  As shown in FIG. 8, when the engaging claw 35 gets over the flange 25, the base insertion hole 29a is restored to its original shape. Thereby, the engaging claw 35 engages with the flange 25. The mounting of the treatment instrument stopper 21 is thus completed.

  After the preparation for endoscopy including the attachment of the treatment instrument plug 21 is completed, the insertion portion 11 is inserted into the patient's body. When the distal rigid portion 11a reaches a desired position in the body, the treatment instrument 14 is inserted from the treatment instrument plug 21 into the treatment instrument insertion channel 16 to perform various treatments. After the treatment with the treatment instrument 14 is completed, the treatment instrument stopper 21 is removed.

  First, a pulling operation is performed toward the front side of the plug body 29. As in the case of mounting the treatment instrument stopper 21, when the inner peripheral surface of the stopper body 29 is pressed by the flange 25, the diameter of the base insertion hole 29a is deformed and the inner diameter of the engaging claw 35 is increased accordingly. When the inner diameter of the engaging claw 35 becomes larger than the outer diameter of the flange 25, the engaging claw 35 gets over the flange 25. As a result, the engagement between the engagement claw 35 and the flange 25 is released.

  As shown in FIG. 9, when the pulling operation is continued, the base end portion 20b and the flange 25 are extracted from the base insertion hole 29a. At the same time, the base insertion hole 29a is restored to its original shape. Thus, the removal of the treatment instrument stopper 21 is completed.

  When a predetermined time elapses after the treatment instrument plug 21 is removed from the package 42, the photocuring portion 31 is completely cured. Thereby, the diameter expansion deformation | transformation of the nozzle | cap | die insertion hole 29a is controlled. For this reason, as shown in FIG. 10, even if the base end portion 20b and the flange 25 are to be inserted into the base insertion hole 29a, the diameter expansion deformation of the base insertion hole 29a is restricted. I cannot get over 25. For this reason, since the insertion of the base 20 into the base insertion hole 29 a is blocked by the engaging claws 35, the treatment instrument stopper 21 cannot be attached to the base 20. As a result, the reuse of the treatment instrument stopper 21 is prevented.

  Since it is possible to prevent the treatment tool stopper 21 from being reused without destroying the treatment tool stopper 21, it is possible to prevent the occurrence of troubles such as debris generated by the destruction entering the treatment tool insertion channel 16. . Further, since it is not necessary to form a fragile part such as a cut in the treatment instrument plug 21, the treatment instrument plug 21 is used by accidentally destroying the fragile part when the treatment instrument plug 21 is attached or at the time of endoscopy. It is prevented from becoming impossible.

  Further, as described in Patent Document 5, it is not necessary to provide an ID tag and a tag reader for the treatment instrument plug 21 and the endoscope 10 respectively, and it is not necessary to provide a circuit for comparing ID information. Reuse can be prevented only by improvement. As a result, it is possible to prevent the treatment instrument stopper 21 from being reused at a lower cost than in the prior art.

  In the above embodiment, the treatment instrument plug 21 is removed from the base 20 before the photocuring part 31 is completely cured, but even if the photocuring part 31 is photocured before this removal, the treatment instrument plug 21 It cannot be reused.

  As shown in FIG. 11, when the photocuring portion 31 is completely cured while the engaging claw 35 is engaged with the flange 25, the photocuring portion 31 engages the engaging claw 35 with the flange 25. Hold in state. For this reason, unless the treatment instrument stopper 21 is destroyed, the treatment instrument stopper 21 can be removed from the base 20. As a result, the treatment instrument stopper 21 is destroyed when it is removed from the base 20, so that the reuse of the treatment instrument stopper 21 is prevented. In this case, it is preferable to remove the treatment instrument plug 21 before the photocuring portion 31 is completely cured, since there is a possibility that fragments generated by destruction may enter the treatment instrument insertion channel 16.

  In the above embodiment, the treatment instrument plug 21 attached to the base 20 of the treatment instrument introduction part 17 has been described as an example. However, the treatment instrument stopper directly attached to the opening 17a of the treatment instrument introduction part 17 is described. The present invention can also be applied to.

  In the embodiment described above, the treatment instrument plug 21 attached to the base 20 leading to the treatment instrument insertion channel 16 has been described as an example. However, for example, the endoscope 10 such as a suction channel or an air / water supply channel is provided inside the endoscope 10. The present invention can be applied to a plug body mounted on a mouth portion that leads to various channels and pipes that are disposed.

  In the said embodiment, although the photocuring part 31 was mentioned and demonstrated as an example as the photocuring part 31, you may form with the various photocurable material which receives the irradiation of light and hardens | cures gradually. Moreover, in the said embodiment, although the plug main body 29 is formed with transparent rubber, you may form with the various elastic materials which have a light transmittance.

  In the embodiment described above, the photocurable photocuring part 31 is provided in the plug body 29 in order to restrict the diameter expansion deformation of the base insertion hole 29a. However, for example, moisture is absorbed instead of the photocuring part 31. Various hardened portions having a curable property with time, such as a hardened portion formed of a material that hardens when heated, may be provided. When the hardened portion is formed of a material that absorbs moisture and hardens, a small hole for ventilation is formed in the plug body.

  In the above embodiment, the endoscope 10 inserted into the trachea has been described as an example. However, for example, various medical endoscopes such as a large intestine endoscope inserted into the large intestine, and other industrial applications such as an industrial use, etc. The present invention can also be applied to endoscopes used for applications.
