Description

Technical Field

[0001] This invention relates to a sterilization device and a sterilization system for endoscopes. Background Technology

[0002] In the medical field, endoscopic examinations are performed by inserting the insertion part of an endoscope into the body of the patient for observation. It is known that, in the waiting state before observation, the endoscope is suspended on a hanger. Furthermore, the hanger holding the endoscope is typically mounted on an endoscope trolley used for carrying and transporting the endoscope, processing unit, and light source device, etc.

[0003] Patent Document 1 describes an endoscope trolley equipped with a hanger for holding an endoscope. This endoscope trolley includes a hanger cover that covers the hanger and a heating mechanism that raises the temperature around the endoscope held in the hanger. This keeps the endoscope clean. Furthermore, in the endoscope trolley described in Patent Document 1, a germicidal lamp is installed inside the hanger cover to inhibit bacterial growth within the hanger cover.

[0004] In the endoscope cart described in Patent Document 2, a sanitary box is installed on the side of the main body of the endoscope cart. The sanitary box contains a hanger, a support for the hanger, and a germicidal lamp. The support has an illumination window, and a germicidal lamp is installed inside. The endoscope suspended on the hanger is irradiated with ultraviolet light from the lit germicidal lamp through the illumination window to sterilize the endoscope.

[0008] Patent Document 2: Japanese Patent Application Publication No. 10-262902 Summary of the Invention

[0009] The technical problem to be solved by the invention

[0010] In the medical field, to take further preventive measures against infectious diseases, the insertion part of an endoscope is inserted into the patient's body for observation. Therefore, sterilization against viruses and other bacteria is very important, especially requiring sterilization just before insertion into the patient's body. However, even if a germicidal lamp is installed inside the hanger cover as in the endoscope trolley described in Patent Document 1 above, the sterilization effect is mainly achieved by the hanger cover, and sterilization of the insertion part of the endoscope is not considered.

[0011] On the other hand, in the endoscope trolley described in Patent Document 2, a germicidal lamp is installed inside the support body of the support bracket. However, due to the way the endoscope is suspended relative to the bracket, the position and amount of ultraviolet light irradiating the endoscope are deviated, thus failing to achieve a high sterilization effect on the insertion part of the endoscope. That is, in the endoscope trolleys described in Patent Documents 1 and 2, sterilization of the insertion part is not considered before it is inserted into the patient's body.

[0012] The purpose of this invention is to provide an endoscope sterilization device and endoscope sterilization system that can achieve a high sterilization effect on the insertion part of the endoscope.

[0054] [First Implementation]

[0055] like Figure 1 As shown, the endoscope system 10 includes an endoscope 12, a light source device 14, a processor device 15, a display 16, a keyboard (not shown), an endoscope sterilization device 18, and an endoscope trolley 20 for carrying and transporting these devices. The endoscope trolley 20 constitutes the endoscope holding device as claimed in the claims. The endoscope 12 captures images of the object being observed. The light source device 14 emits illumination light to illuminate the object being observed. The processor device 15 controls the endoscope system 10. The display 16 is a display unit that displays observation images, etc., based on the endoscope images. The keyboard is an input device for inputting settings, etc., to the processor device 15, etc.

[0056] The endoscope 12 has a flexible part 12a, an operating part 12b connected to the base portion of the flexible part 12a, and a curved part 12c provided at the front end side of the flexible part 12a (see reference). Figure 2 ) and the front end 12d (reference) Figure 2The insertion portion of the endoscope 12 consists of a flexible portion 12a, a curved portion 12c, and a front end portion 12d. By operating the bend knob 12e of the operating portion 12b, the curved portion 12c bends. As a result, the front end portion 12d faces the desired direction. The endoscope 12 has a lanyard 12f that connects to the light source device 14 and the processor device 15, being optically connected to the light source device 14 and electrically connected to the processor device 15.

[0057] The endoscope sterilization device 18 and the endoscope trolley 20 constitute the endoscope sterilization system of the claims. The endoscope trolley 20 includes a frame base 21, four casters 22, supports 23 and 24, a top plate 26, shelves 27 and 28, a bracket 29, and two hangers 30. The frame base 21 is generally rectangular, with casters 22 at its four corners. The supports 23 and 24 are columnar members erected from both sides of the frame base 21. The top plate 26 is generally rectangular and is disposed on the upper ends of the supports 23 and 24. The two sides of the top plate 26 are fixed to the inner sides of the upper ends of the supports 23 and 24.

[0058] Shelves 27 and 28 are roughly rectangular and fixed to the inner side of the middle portion of supports 23 and 24. Shelves 27 and 28 separate the frame base portion 21 and the top plate 26. Each caster 22 is provided with a stop bar 22a to limit its rotation. When the stop bar 22a is lowered, the rotation of the caster 22 is restricted; when the stop bar 22a is raised, the caster 22 can rotate.

[0059] Top plate 26, shelves 27, and 28 are panels on which endoscopic equipment, etc., are mounted. Figure 1 In the example shown, a processor device 15 and a light source device 14 are mounted on the upper surface of shelf 27, and an endoscope sterilization device 18 is mounted on the upper surface of shelf 28.

[0060] A handle 26a is provided at the front of the top plate 26. The user can easily move the endoscope trolley 20 by holding the handle 26a. A drawer section 26b is provided on the lower surface of the top plate 26. The drawer section 26b houses a keyboard or the like for inputting to the processor device 15, etc. The display 16 is fixed to a bracket 29 mounted on the upper end of the left support column 24, and is connected to the processor device 15 via wiring within the bracket 29 and the support column 24.

[0061] The suspender 30 is mounted on the upper end of the right-side support column 23 via a suspender bracket 31. The suspender bracket 31 consists of an L-shaped bracket member 31a and a straight bracket member 31b. One end of the bracket member 31a is rotatably mounted to the support column 23. The suspender 30 is fixed to the bracket member 31b. As described later, the suspender 30 holds the operating part 12b of the endoscope 12. The bracket member 31b is rotatably connected to the other end of the bracket member 31a. Thus, by rotating the bracket members 31a and 31b relative to the support column 23, the position of the suspender 30 and the endoscope 12 held by the suspender 30 can be adjusted.

[0062] The hanger 30 has a notch or slot that holds the operating part 12b of the endoscope 12, thereby suspending the endoscope 12 on the hanger 30. When the operating part 12b is held on the hanger 30, the downward direction of the flexible part 12a, which droops due to its own weight, is parallel to the vertical direction Z. The hanger 30 is adjusted so that the front end 12d does not contact the ground when the endoscope 12 is suspended. In addition, the number of hangers 30 is not limited to two; a suitable number of hangers 30 is provided, corresponding to the purpose of using the endoscope 12 or the size of the endoscope trolley 20 and the hanger bracket 31.

[0063] like Figure 2 As shown, the endoscope sterilization device 18 includes a frame 41 as a housing, sterilization light sources 42 and 43, and a light source control unit 44 (see reference). Figure 4 The endoscope sterilization device 18 sterilizes at least a portion of the insertion portion of the endoscope 12. In this embodiment, the endoscope sterilization device 18 mainly sterilizes the anterior portion 12d.

[0064] The frame 41 is formed as a bottomed cylindrical shape having an opening 41A, a peripheral surface 41B, and a rear surface 41C. The peripheral surface 41B is formed as a quadrilateral cylindrical shape constituting the upper and lower surfaces and left and right sides of the frame 41. The rear surface 41C blocks the rear end of the peripheral surface 41B. The rear surface 41C corresponds to the bottom surface in the claims.

[0065] The interior of the frame 41, surrounded by the peripheral surface 41B and the rear surface 41C, is a sterilization space 41D, which is the space irradiated with the sterilizing ultraviolet light described later. The sterilization space 41D is formed to be at least larger than the outer diameter and axial length of the front end portion 12d, and is capable of accommodating the front end portion 12d. The opening 41A is a circular through hole located on the front surface of the peripheral surface 41B, with an inner diameter at least larger than the outer diameter of the front end portion 12d. The opening direction of the opening 41A is the same as that of the central axis CL of the opening 41A (see reference). Figure 3The parallel direction intersects the downward direction of the flexible part 12a, i.e., the vertical direction Z. Furthermore, the opening direction of the opening 41A varies depending on the orientation of the endoscope sterilization device 18, but in this embodiment, for ease of explanation, the front-to-back direction X of the endoscope trolley 20 is used as the opening direction of the opening 41A. At least a portion of the front end part 12d, serving as the insertion part, can be inserted into the sterilization space 41D from outside the frame 41 through the opening 41A. A power switch 45 is provided near the opening 41A.

[0066] A sterilization light source 42 is disposed on the rear surface 41C of the frame 41. The sterilization light source 42 uses an ultraviolet light source. The sterilization light source 42 is either an excimer lamp or an ultraviolet LED (light-emitting diode). Furthermore, an excimer lamp is a discharge lamp that emits light from excimers formed by rare gas atoms or rare gas atoms and halogen atoms by utilizing the characteristic of dielectric barrier discharge to produce multiple short-duration discharges. Structurally, it can be either a double cylindrical type or a flat plate type. For example, a flat plate type excimer lamp is used as the sterilization light source 42.

[0067] In excimer lamps, the preferred ultraviolet light source is a first ultraviolet light emitting a peak wavelength of 222 nm (±10 nm) and a wavelength band of 200 nm or more and 280 nm or less, more preferably a wavelength band of 200 nm or more and 230 nm or less. The biotransmittance of the first ultraviolet light is lower than that of the 254 nm ultraviolet light (specific ultraviolet light) which has a higher light intensity. For example, the corneal transmittance (the proportion of light incident on the cornea that is absorbed by the cornea) is 0.01 in the case of the first ultraviolet light, while it is 30% in the case of the specific ultraviolet light. Therefore, the first ultraviolet light is safe for the skin and eyes of humans and animals, and possesses the inherent bactericidal and viral inactivation capabilities of ultraviolet light.

[0068] Ultraviolet (UV) LEDs preferably emit deep UV light, specifically second UV light, with wavelengths below 300 nm. Second UV light has the ability to destroy the genetic information of viruses and bacteria, thus providing sterilization effects on water and air. For example, second UV light has a high sterilization effect against human coronavirus (HCoV-229E). Furthermore, UV LEDs preferably possess waterproof or heat dissipation capabilities. Compared to mercury lamps, UV LEDs have a smaller environmental impact.

[0069] The sterilization light source 42 is exposed from the innermost surface of the sterilization space 41D. The sterilization light source 42 includes optical components (not shown) that diffuse ultraviolet light into the sterilization space 41D, and can diffuse ultraviolet light at least within the irradiation range that completely includes the surface of the front end 12d.

[0070] A sterilization light source 43 is positioned on the periphery 41B of the frame 41. Figure 2 and Figure 3 In the example shown, the sterilization light source 43 is a long strip-shaped sterilization light source disposed on the upper and lower surfaces and left and right sides of the sterilization space 41D, and arranged parallel to the front-back direction X. In addition, the sterilization light source 43 uses the same ultraviolet light source as the sterilization light source 42 described above, but preferably uses a cylindrical excimer lamp.

[0071] like Figure 4 As shown, the sterilization light sources 42 and 43 are controlled by the light source control unit 44. The sterilization light sources 42 and 43, which are controlled by the light source control unit 44 to begin irradiating ultraviolet light, automatically stop irradiating ultraviolet light after a predetermined time (several seconds to several minutes) has elapsed, for example, when measured by a timer built into the light source control unit 44. Furthermore, the control of the sterilization light sources 42 and 43 based on the light source control unit 44 is not limited to this. For example, control can be achieved by having an optical or physical sensor in the frame 41 that detects the insertion state of the insertion part. When the sensor detects that the insertion part (any one of the flexible part 12a, the curved part 12c, and the front end 12d) has been inserted into the frame 41, the sensor becomes in an on state and begins irradiating ultraviolet light; when the sensor detects that the insertion part has been removed from the frame 41, the sensor becomes in an off state and stops irradiating.

[0072] Furthermore, the control of the sterilization light source 42 based on the light source control unit 44 is not limited to the control described above. For example, the irradiation of ultraviolet light can be stopped when a predetermined condition is met before a predetermined time has elapsed. The predetermined condition mentioned here refers, for example, to an endoscope sterilization device 18 having an optical or physical sensor in the frame 41 that detects the insertion state of the insertion part. When the insertion part has been removed from the frame 41, the light source control unit 44 determines that the predetermined condition has been met and stops the irradiation of ultraviolet light.

[0073] Furthermore, the control of the sterilization light source 42 based on the light source control unit 44 is performed as follows: if the aforementioned predetermined conditions are met before a predetermined time has elapsed, and ultraviolet irradiation is temporarily stopped, the user is notified if the actual irradiation time is shorter than the preset time. Then, after reporting, the light source control unit 44 restarts ultraviolet irradiation based on the sterilization light source 42 once the predetermined conditions are lifted. The condition for lifting the predetermined conditions is, for example, detecting that the insertion part has been re-inserted into the frame 41. Additionally, notification of short irradiation time can be made, for example, by emitting a sound or changing the display based on an indicator.

[0074] The function of the above structure will be explained. Before observation based on the endoscope 12, the cleaned operating part 12b of the endoscope 12 is held on the hanger 30. With the operating part 12b held on the hanger 30, the flexible part 12a hangs down due to its own weight. The doctor or medical personnel who is the user operates the power switch 45 of the endoscope sterilization device 18 to turn on the power. Then, the front part 12d is inserted into the interior of the frame 41, i.e., the sterilization space 41D, through the opening 41A. At least a portion of the inserted part, including the front part 12d, is irradiated with ultraviolet light from the sterilization light sources 42 and 43. By irradiating with ultraviolet light, the front part 12d is reliably sterilized, and a high sterilization effect can be obtained.

[0075] Furthermore, since ultraviolet light with a wavelength range of 200nm to 280nm is used as the ultraviolet light irradiating at least a portion of the insertion part from the sterilization light source 42, 43, sterilization can be performed more reliably.

[0076] [Second Implementation]

[0077] In the first embodiment described above, an endoscope sterilization device 18 was exemplified as one mounted on an endoscope trolley 20, but it is not limited thereto. In the second embodiment described below, an endoscope sterilization device mounted on an endoscope trolley 20 will be described. Furthermore, the structure of the endoscope trolley 20 is the same as in the first embodiment described above, and its description is omitted.

[0078] like Figure 5 As shown, the endoscope sterilization device 50 is mounted on the support column 23 of the endoscope trolley 20. The endoscope sterilization device 50 and the endoscope trolley 20 constitute the endoscope sterilization system of the claims. The endoscope sterilization device 50 is disposed below the hanger 30. That is, when the operating part 12b is held on the hanger 30, the front end 12d of the endoscope 12, located on the front end side in the downward direction (i.e., the vertical direction Z) where the flexible part 12a droops due to its own weight, is inserted into the endoscope sterilization device 50 when the operating part 12b of the endoscope 12 is held on the hanger 30.

[0079] The endoscope sterilization device 50 includes a frame 51 serving as a housing, sterilization light sources 52 and 53, a light source control unit (not shown), and a power switch 54. The endoscope sterilization device 50 sterilizes at least a portion of the insertion portion of the endoscope 12. In this embodiment, the endoscope sterilization device 50 primarily sterilizes the tip 12d. Furthermore, the frame 51 has space capable of accommodating multiple tip 12d portions. Figure 5 In the example shown, the endoscope sterilization device 50 sterilizes both anterior ends 12d simultaneously.

[0080] like Figure 6 As shown, the frame 51 is formed as a bottomed cylindrical shape having an opening 51A, a peripheral surface 51B, and a bottom surface 51C. The peripheral surface 51B is formed as a quadrilateral cylindrical shape constituting the front and rear surfaces and left and right sides of the frame 51. The bottom surface 51C blocks the lower end of the peripheral surface 51B.

[0081] The interior of the frame 51, surrounded by the peripheral surface 51B and the bottom surface 51C, is a sterilization space 51D, which is irradiated with ultraviolet light for sterilization. The sterilization space 51D is formed to be at least larger than the outer diameter and axial length of the front end portion 12d, and can accommodate multiple front end portions 12d. The opening 51A is located on the upper surface of the peripheral surface 51B and is a rectangular through hole through which multiple front end portions 12d pass. The opening direction of the opening 51A is parallel to the vertical direction Z, which is the downward direction of the flexible part 12a. Thus, the front end portion 12d can be inserted into the sterilization space 51D from the outside of the frame 51 through the opening 51A. A power switch 54 is provided near the opening 51A.

[0082] A sterilization light source 52 is disposed on the bottom surface 51C of the frame 51. The sterilization light source 52 uses an ultraviolet (UV) light source. The sterilization light source 52 protrudes from the lowest surface of the sterilization space 51D. The sterilization light source 52 includes optical components (not shown) that diffuse UV light into the sterilization space 51D, ensuring that the UV light is diffused at least within the irradiation range completely encompassing the surface of the front end 12d. Figure 6 In the example shown, two sterilization light sources 52 are provided corresponding to the position of the insertion front end 12d.

[0083] A sterilization light source 53 is disposed on the peripheral surface 51B of the frame 51. The sterilization light source 53 is a long strip-shaped sterilization light source disposed on the front and rear surfaces and left and right sides of the sterilization space 51D, and is arranged parallel to the vertical direction Z. Furthermore, the sterilization light sources 52 and 53 use the same ultraviolet light sources as the sterilization light sources 42 and 43 in the first embodiment described above; however, a flat-panel excimer lamp is preferred for the sterilization light source 52, and a cylindrical excimer lamp is preferred for the sterilization light source 53.

[0084] The sterilization light sources 52 and 53 are controlled by the light source control unit. The light source control unit in this embodiment performs the same control as the light source control unit 44 in the first embodiment described above, automatically stopping ultraviolet irradiation based on the sterilization light sources 52 and 53 after a predetermined time (several seconds to several minutes). The control of the sterilization light sources 52 and 53 based on the light source control unit is not limited to this; it can also be controlled in the following way: if the endoscope sterilization device 50 or the endoscope cart 20 is equipped with a human sensor or similar device that detects the location of people around the frame 51, ultraviolet irradiation begins when someone is detected around the frame 51, and stops when no one is detected around the frame 51.

[0085] Furthermore, the control of the sterilization light sources 52 and 53 based on the light source control unit is as follows: when a predetermined condition is met before a predetermined time has elapsed, the ultraviolet irradiation is stopped; or when the predetermined condition is met before a predetermined time has elapsed and the ultraviolet irradiation is temporarily stopped, the user is notified if the actual irradiation time is shorter than the preset time. Additionally, as for the condition of meeting the predetermined condition, similar to the above embodiment, the light source control unit can determine that the predetermined condition has been met and stop the ultraviolet irradiation when the insertion part has been removed from the frame 51. Alternatively, if the endoscope sterilization device 50 or the endoscope trolley 20 is equipped with a human detection sensor, the light source control unit can determine that the predetermined condition has been met and stop the ultraviolet irradiation when no one is detected around the frame 51.

[0086] The function of the above structure will be explained. Before observation based on the endoscope 12, with the operating part 12b of the endoscope 12 held on the hanger 30, as described above, the endoscope sterilization device 50 is positioned in the downward direction where the flexible part 12a hangs down due to its own weight. Therefore, with the operating part 12b held on the hanger 30, the endoscope sterilization device 50 is located near the front end 12d, allowing the user (doctor or medical personnel) to easily insert the front end 12d into the sterilization space 51D inside the frame 51 from the opening 51A. Then, the doctor or medical personnel operates the power switch 54 of the endoscope sterilization device 50 to turn on the power. Similar to the first embodiment described above, the front end 12d is reliably sterilized by irradiating with ultraviolet light, achieving a high sterilization effect.

[0087] [Third Implementation]

[0088] In the third embodiment described below, in addition to the structures of the first and second embodiments described above, a cover member constituting at least a portion of the bottom surface or the peripheral surface is provided, which is movable in a manner that exposes the interior of the receiving portion. Figure 7 The endoscope sterilization device 60 shown in this embodiment can be used by mounting it on the endoscope trolley 20 in the same manner as in the first embodiment described above, or it can be used by installing it on the endoscope trolley 20 in the same manner as in the second embodiment described above.

[0089] The endoscope sterilization device 60 includes a frame 61 serving as a housing, sterilization light sources 62 and 63, a light source control unit (not shown), a cover member 64, and a power switch 65. The endoscope sterilization device 60 sterilizes at least a portion of the insertion portion of the endoscope 12, primarily sterilizing the tip 12d. Furthermore, the frame 61 has space capable of accommodating multiple tip 12d portions.

[0090] The frame 61 is formed as a bottomed cylindrical shape having an opening 61A, a peripheral surface 61B, and a bottom surface 61C. The peripheral surface 61B is formed as a cylinder extending in the vertical direction Z. The bottom surface 61C blocks the lower end of the peripheral surface 61B. The interior of the frame 61, surrounded by the peripheral surface 61B and the bottom surface 61C, is a sterilization space 61D, which is a space irradiated with ultraviolet light for sterilization. The sterilization space 61D is formed to be at least larger than the outer diameter and axial length of the front end portion 12d. The opening 61A is located on the upper surface of the peripheral surface 61B and is a circular through hole through which multiple flexible parts 12a pass. Thus, flexible parts 12a can be inserted into the sterilization space 61D from the outside of the frame 61 through the opening 61A. A power switch 65 is provided near the opening 61A.

[0091] A sterilization light source 62 is disposed on the bottom surface 61C of the frame 61. The sterilization light source 62 uses an ultraviolet light source. The sterilization light source 62 is exposed from the lowest surface in the sterilization space 61D. The sterilization light source 62 includes optical components (not shown) that diffuse ultraviolet light into the sterilization space 61D, and can diffuse ultraviolet light at least within the irradiation range that completely includes the surface of the front end 12d.

[0092] A sterilization light source 63 is disposed on the peripheral surface 61B of the frame 61. The sterilization light source 63 is a long, strip-shaped sterilization light source disposed on the inner peripheral surface of the sterilization space 61D, and is arranged parallel to the vertical direction Z. Furthermore, as described later, the cover member 64 constitutes part of the peripheral surface 61B; therefore, a portion of the plurality of sterilization light sources 63 is disposed on the inner peripheral surface of the cover member 64. Additionally, the sterilization light sources 62 and 63 use the same ultraviolet light sources as the sterilization light sources 42, 43, 52, and 53 in the first embodiment described above. However, a flat-panel excimer lamp is preferably used as the sterilization light source 62, and a cylindrical excimer lamp is preferably used as the sterilization light source 63. The sterilization light sources 62 and 63 are controlled by a light source control unit. The light source control unit in this embodiment performs the same control as the light source control unit 44 in the first embodiment described above, therefore, its description is omitted.

[0093] The cover member 64 forms at least a portion of the peripheral surface 61B and is configured to be movable relative to the frame 61. Specifically, it is rotatably connected to the frame 61 via a rotation axis 64A. The cover member 64 can rotate between a closed position (indicated by the double-dotted line) that covers the sterilization space 61D of the frame 61 and an open position (indicated by the solid line) that exposes the sterilization space 61D of the frame 61. Thus, in addition to the effects of the first and second embodiments described above, when cleaning the endoscope sterilization device 60, the cover member 64 can be moved to the open position to expose the interior of the frame 61, i.e., the sterilization space 61D. Therefore, cleaning of the endoscope sterilization device 60 can be performed easily.

[0094] Furthermore, the cover component 64 can be configured to be easily detached from the frame 61. In this case, for example, it can be configured to provide a locking claw on one of the frame 61 and the cover component 64 and a locking hole on the other, so that the frame 61 and the cover component 64 can be integrated by locking them, or the frame 61 and the cover component 64 can be separated by releasing the locking.

[0095] In addition, in the first to third embodiments described above, sterilization light sources are provided on the periphery and bottom surfaces of the frames 41, 51, and 61, respectively. However, the present invention is not limited to this. For example, a sterilization light source may be provided on any one of the periphery and bottom surfaces of the frames 41, 51, and 61, and a reflective material may be provided inside the other (at a position opposite to the sterilization spaces 41D, 51D, and 61D) to reflect the ultraviolet rays from the sterilization light source.

[0096] [First Variation]

[0097] Furthermore, as a variation, it can be as follows: Figure 8 As shown, in addition to the structure of the endoscope sterilization device and endoscope sterilization system of the first to third embodiments described above, it also includes an insertion part holding part 66 and an insertion amount detection part 67.

[0098] Insertion holding part 66 (see also reference) Figure 5 For example, it is installed on the endoscope trolley 20. The insertion part holding part 66 is disposed near the bracket 30, specifically, when the operating part 12b is held on the bracket 30, at the position of the drooping flexible part 12a. Figure 8 (The positions indicated by solid lines) are consistently configured. Figure 5 In the example shown, the insertion holding portion 66 holds the flexible portion 12a housed in the frame 51 of the endoscope sterilization device 50. The insertion holding portion 66 has, for example, an opening 66a with an inner diameter matching the outer diameter of the flexible portion 12a, and a notch 66b cut from the side of the insertion holding portion 66 toward the opening 66a. Thus, the flexible portion 12a inserted through the notch 66b is held in the opening 66a within the insertion holding portion 66.

[0099] In applicable Figure 5In the example shown, the insertion depth detection unit 67 detects the insertion depth of the flexible part 12a relative to the frame 51 of the endoscope sterilization device 50. Furthermore, the insertion depth detection unit 67 has the same known structure as that for detecting the insertion depth of the insertion part into the subject body. A measuring scale 12g for measuring the insertion length of the insertion part into the subject body is provided on the outer peripheral surface of the flexible part 12a of the endoscope 12. A scale detection sensor 71 for detecting the measuring scale 12g is provided on the insertion part holding part 66. The scale detection sensor 71 sends a detection signal for the detected measuring scale 12g to the insertion depth detection unit 67. The positional relationship between the frame 51 and the insertion part holding part 66 is predetermined, therefore the insertion depth detection unit 67 detects the insertion depth of the flexible part 12a relative to the frame 51 based on the detection signal from the scale detection sensor 71.

[0100] The insertion depth detection unit 67 sends the detected insertion depth of the endoscope 12 to the light source control unit of the endoscope sterilization device 50. The light source control unit of the endoscope sterilization device 50 controls the sterilization light sources 52 and 53 based on the insertion depth detected by the insertion depth detection unit 67. For example, it controls the ultraviolet irradiation based on the sterilization light sources 52 and 53 when the insertion depth of the insertion portion relative to the frame 51 is above a predetermined value, and stops the ultraviolet irradiation based on the sterilization light sources 52 and 53 when the insertion depth of the insertion portion relative to the frame 51 is less than the predetermined value.

[0101] In addition, Figure 5 and Figure 8 The example shown illustrates an application of the insertion holding part 66 and the insertion amount detection part 67 to the endoscope sterilization device 50 and endoscope sterilization system of the second embodiment, but it can also be applied to the endoscope sterilization device and endoscope sterilization system of the first and third embodiments.

[0102] Furthermore, in the above-described modified example, when the operating part 12b is held on the hanger 30, the position of the insertion part holding part 66 and the drooping flexible part 12a ( Figure 8 The position of the flexible part 12a, indicated by the solid line, is consistent with the position of the insertion part holding part 66. On the other hand, when the position of the flexible part 12a hanging from the holding position of the hanger 30 is inconsistent with the position of the insertion part holding part 66 ( Figure 8 The position of the flexible part 12a (indicated by the double-dotted line) can be positioned by using the insertion holding part 66 as a positioning part, bending a portion of the flexible part 12a and holding it in the opening 66a. Thus, the position of the flexible part 12a can be determined at a location where it can be inserted into the receiving part of the endoscope sterilization device.

[0103] [Second Variation]

[0104] The endoscopic sterilization devices in the above embodiments are used either separately from the endoscopic trolley 20, which serves as an endoscope holding device, or are always fixed to the endoscopic trolley 20. However, the present invention is not limited to this, and may also be configured to allow for the attachment and detachment of part or all of the endoscopic sterilization device from the endoscopic trolley 20. Figure 9 and Figure 10 In the example shown, the frame 76, which serves as the housing of the endoscope sterilization device 75, can be loaded and unloaded onto the endoscope trolley 20.

[0105] The endoscope sterilization device 75 is mounted on the support 23 of the endoscope trolley 20 in the same manner as the endoscope sterilization device 50 in the second embodiment described above. The endoscope sterilization device 75 includes a frame 76 and a light source unit 77. The frame 76 is formed in the same manner as the frame 51 of the endoscope sterilization device 50 in the second embodiment described above, and is a bottomed cylindrical shape having an opening 76A, a peripheral surface 76B, and a bottom surface 76C.

[0106] like Figure 11 As shown, a fitting opening 76D is formed in the peripheral surface 76B at a position opposite to the support column 23. The fitting opening 76D is a quadrilateral opening cut from the outer peripheral surface of the peripheral surface 76B. A transmission window 76E is provided in the inner peripheral surface of the peripheral surface 76B at a position opposite to the fitting opening 76D. The transmission window 76E allows ultraviolet light from the sterilization light source 78 (described later) to pass through. Alternatively, the transmission window 76E may also function as a diffuser plate to diffuse ultraviolet light.

[0107] Furthermore, a reflective material 76F is provided on the inner peripheral surface of the peripheral surface 76B. The reflective material 76F reflects ultraviolet rays from the sterilization light source 78, which will be described later. In addition, the structure of the fitting opening 76D is not limited to the above structure. It is also possible that the transmission window 76E is not provided, but rather a through hole extending from the outer peripheral surface of the peripheral surface 76B to the inner peripheral surface.

[0108] The light source unit 77 includes a sterilization light source 78 and a fitting member 79 for holding the sterilization light source 78, and is fixed to the support column 23. The fitting member 79 is shaped as a quadrilateral cross-section that fits into the fitting opening 76D. By fitting the fitting member 79 into the fitting opening 76D, the frame 76 can be detachably mounted on the endoscope trolley 20. When the fitting opening 76D is fitted with the fitting member 79, the sterilization light source 78 is exposed inside the frame 76 through the transmission window 76E. The sterilization light source 78 uses the same ultraviolet light source as the sterilization light sources 42 and 43 in the first embodiment described above. The reflective material 76F reflects the ultraviolet light from the sterilization light source 78, thus allowing ultraviolet light to irradiate the entire interior of the frame 76. As described above, since the frame 76 can be detached from the endoscope trolley 20, the sterilization light source 78 is only provided on the endoscope trolley 20 side, thus achieving low cost. Furthermore, it allows for easy cleaning of the endoscope sterilization device 75.

[0109] In addition, Figures 9-11 In the example shown, for an endoscope trolley, a portion of the endoscope sterilization device can be loaded and unloaded onto the endoscope trolley 20, but it is not limited to this; it can also be configured to load and unload the entire endoscope sterilization device onto the endoscope trolley 20.

[0110] [Fourth Implementation]

[0111] In the first to third embodiments described above, an endoscope sterilization device and an endoscope sterilization system were illustrated, which sterilize at least a portion of the flexible part 12a of the endoscope 12. These primarily sterilize the tip 12d, but the present invention is not limited to this; the entire flexible part 12a can also be sterilized. In the fourth embodiment described below, an endoscope sterilization system is shown, which includes a sliding mechanism by which the endoscope sterilization device is slid, thereby sterilizing the entire flexible part 12a.

[0112] like Figure 12 As shown, the endoscope sterilization device 80 and the sliding mechanism 81 are mounted on the endoscope trolley 20. Furthermore, the structure of the endoscope trolley 20 is the same as in the first embodiment described above, and therefore description is omitted. The endoscope sterilization device 80, the sliding mechanism 81, and the endoscope trolley 20 constitute the endoscope sterilization system of the claims.

[0113] like Figure 13As shown, the endoscope sterilization device 80 includes an insertion part 82, sterilization light sources 83 and 84, a light source control part (not shown), a mounting plate 85, and a power switch 86. The endoscope sterilization device 80 is disposed below the hanger 30. That is, when the operating part 12b is held on the hanger 30, it is disposed at a position corresponding to the flexible part 12a in the downward direction (i.e., the vertical direction Z) where the flexible part 12a droops due to its own weight.

[0114] The insertion portion 82 is U-shaped and has at least a peripheral surface portion 87 opposite to the flexible portion 12a. As described above, the endoscope sterilization device 80 is disposed below the hanger 30, so that when the operating portion 12b of the endoscope 12 is held in the hanger 30, the flexible portion 12a can be inserted into the through insertion portion 82.

[0115] In this embodiment, the opposing straight sections 87A of the peripheral surface 87 are arranged parallel to the longitudinal direction X of the endoscope trolley 20. The interior of the insertion portion 82 surrounded by the peripheral surface 87 is a sterilization space 87B, which is a space irradiated with sterilizing ultraviolet light by sterilization light sources 83 and 84. Thus, when the operating part 12b is held in the hanger 30, the sterilization light sources 83 and 84 can irradiate at least a portion of the flexible part 12a that droops due to its own weight and is inserted through the insertion portion 82 with sterilizing ultraviolet light. The sterilization space 87B is formed to be at least larger than the outer diameter and axial length of the front end portion 12d.

[0116] The sterilization light source 83 uses an ultraviolet light source. One or more sterilization light sources 83 are disposed on the peripheral surface 87, protruding from the innermost surface in the sterilization space 87B. The sterilization light source 83 includes optical components (not shown) that diffuse ultraviolet light to irradiate the sterilization space 87B.

[0117] A sterilization light source 84 is disposed on the straight portion 87A of the peripheral surface 87. The sterilization light source 84 is a long, strip-shaped sterilization light source disposed opposite each other in the sterilization space 87B, and arranged parallel to the front-rear direction X. Furthermore, the sterilization light sources 83 and 84 use the same ultraviolet light sources as the sterilization light sources 42 and 43 in the first embodiment described above; however, a flat-panel excimer lamp is preferably used as the sterilization light source 83, and a cylindrical excimer lamp is preferably used as the sterilization light source 84. The sterilization light sources 83 and 84 are controlled by a light source control unit. The light source control unit in this embodiment performs the same control as the light source control unit 44 in the first embodiment described above, therefore, a description is omitted.

[0118] The mounting plate 85 is integrally formed with the insertion part 82. The mounting plate 85 is formed into a plate shape extending in the front-rear direction X. A fitting member 88 constituting the sliding mechanism 81 is integrally formed on the mounting plate 85 (see reference). Figure 14The fitting component 88 will be described later. Furthermore, the mounting plate 85 has a recess 85A that is slightly recessed from the surrounding area, making it easy for the user to grip. A power switch 86 is also provided on the mounting plate 85.

[0119] The sliding mechanism 81 includes a fitting member 88, a groove 89, and a speed attenuation mechanism 91. The groove 89 is formed on the side of the support column 23 and is a straight groove extending in the vertical direction Z. The fitting member 88 is disposed in the mounting plate 85 at a position opposite to the groove 89. The fitting member 88 has an integrally formed fitting portion 88A with the same width as the groove 89 and an anti-detachment portion 88B with a width larger than that of the groove 89. The anti-detachment portion 88B prevents the fitting member 88 from disengaging from the groove 89.

[0120] like Figure 14 As shown, the fitting portion 88A and the groove 89 slide freely into each other. Thus, the endoscope sterilization device 80 is held in the groove 89 in a manner that allows it to slide along the vertical direction Z. That is, the endoscope sterilization device 80 can slide along the downward direction of the flexible portion 12a, which sags due to its own weight.

[0121] The speed attenuation mechanism 91 reduces the sliding speed of the endoscope sterilization device 80. Specifically, the speed attenuation mechanism 91 is, for example, composed of a gas spring, and is disposed between the endoscope sterilization device 80 and the support column 23. Furthermore, in Figure 13 and Figure 14 For ease of illustration, the speed attenuation mechanism 91 is arranged on the outside of the support column 23, but it is actually arranged in a position that cannot be seen from the outside, such as inside the support column 23.

[0122] As is well known, a pneumatic spring is a spring that utilizes a reaction force based on the elasticity of the gas sealed in the cylinder when compressed. The pneumatic spring is installed in a state of contraction along the direction of compression of the sealed gas, and always generates a reaction force on the endoscope sterilization device 80 in the opposite direction to its descent based on its own weight, i.e., in the direction on the endoscope sterilization device 80. Furthermore, the speed attenuation mechanism 91 is not limited to the above structure; it can be any mechanism that attenuates the sliding speed of the endoscope sterilization device 80. For example, it can be that either the slide groove 89 or the fitting member 88 uses a component with high frictional resistance, and the sliding speed of the endoscope sterilization device 80 is attenuated by the frictional force generated between the slide groove 89 and the fitting member 88.

[0123] The function of the above structure will be explained. Before observation based on the endoscope 12, with the operating part 12b of the endoscope 12 held on the hanger 30, as described above, the flexible part 12a can be inserted into the through insertion part 82. Then, the doctor or medical personnel, as the user, operates the power switch 86 of the endoscope sterilization device 80 to turn on the power. Then, the sterilization light sources 83 and 84 can irradiate at least a portion of the flexible part 12a inserted through the insertion part 82 with sterilization ultraviolet light. The doctor or medical personnel holds the endoscope sterilization device 80, for example, by sliding it to the upper end of the slide 89 and releasing the holding of the endoscope sterilization device 80, allowing it to gradually descend under its own weight. When sliding the endoscope sterilization device 80, the entire flexible part 12a can be sterilized by irradiating the flexible part 12a with sterilization ultraviolet light based on the sterilization light sources 83 and 84. By irradiating the entire soft part 12a with ultraviolet light, a high sterilization effect can be reliably achieved.

[0124] Furthermore, in the fourth embodiment described above, the sliding mechanism 81 is exemplified as a way for the user to manually move the endoscope sterilization device 80, but it is not limited to this. Instead of the above structure, a sliding mechanism may be used, for example, which has a motor as a drive source and a transmission mechanism that converts the rotational motion of the motor into linear motion, so as to automatically slide the endoscope sterilization device 80.

[0125] [Fifth Implementation]

[0126] In the fourth embodiment described above, an endoscope sterilization system was illustrated in which the endoscope sterilization device is slidable by a sliding mechanism to sterilize the entire flexible part 12a of the endoscope 12. However, the present invention is not limited to this, and the endoscope sterilization device can also be held by a user to sterilize the entire flexible part 12a of the endoscope 12. In the fifth embodiment described below, an endoscope sterilization device and an endoscope sterilization system with a holding part integrally provided for user holding are shown.

[0127] like Figure 15 As shown, the endoscope sterilization device 100 is used together with the endoscope trolley 20. Furthermore, in Figure 15 To avoid complications, the illustration of display 16 is omitted. The endoscope sterilization device 100 and the endoscope trolley 20 constitute the endoscope sterilization system of the claims. Furthermore, the structure of the endoscope trolley 20 is the same as in the first embodiment described above, and its description is omitted.

[0128] like Figure 16As shown, the endoscope sterilization device 100 includes a insertion part 101, sterilization light sources 102 and 103, a light source control part (not shown), a holding part 104, and a power switch 105. The insertion part 101 is U-shaped and has at least a peripheral surface 106 opposite to the flexible part 12a. When the operating part 12b of the endoscope 12 is held on the hanger 30 and the insertion part 101 is arranged around the flexible part 12a, the flexible part 12a can be inserted through the insertion part 101.

[0129] The peripheral surface 106 has straight sections 106A facing each other. The interior of the insertion portion 101 surrounded by the peripheral surface 106 is a sterilization space 106B, which is a space irradiated with sterilizing ultraviolet light by sterilization light sources 102 and 103. Thus, when the operating part 12b is held on the hanger 30 and the insertion portion 101 is arranged around the flexible part 12a (at a position facing the outer peripheral surface of the flexible part 12a), the sterilization light sources 102 and 103 can irradiate at least a portion of the flexible part 12a that droops due to its own weight and is inserted through the insertion portion 101 with sterilizing ultraviolet light. The sterilization space 106B is formed to be at least larger than the outer diameter and axial length of the front end portion 12d.

[0130] The sterilization light source 102 uses an ultraviolet light source. One or more sterilization light sources 102 are disposed on the peripheral surface 106, exposed from the innermost surface in the sterilization space 106B. The sterilization light source 102 includes optical components (not shown) that diffuse ultraviolet light to irradiate the sterilization space 106B.

[0131] A sterilization light source 103 is disposed on the straight portion 106A of the peripheral surface 106. The sterilization light source 103 is an elongated sterilization light source positioned opposite each other within the sterilization space 106B. Furthermore, the sterilization light sources 102 and 103 use the same ultraviolet light sources as the sterilization light sources 42 and 43 in the first embodiment described above; however, a flat-panel excimer lamp is preferred for sterilization light source 102, and a cylindrical excimer lamp is preferred for sterilization light source 103. The sterilization light sources 102 and 103 are controlled by a light source control unit. The light source control unit in this embodiment performs the same control as the light source control unit 44 in the first embodiment described above, therefore, its description is omitted.

[0132] The grip portion 104 and the insertion portion 82 are integrally formed. The grip portion 104 is plate-shaped. The grip portion 104 is shaped to a size and thickness that is easy for a person's hand to hold. Furthermore, the grip portion 104 has a recess 104A that is slightly recessed from the surrounding area, making it easy for the user to grip. A power switch 105 is also provided in the grip portion 104.

[0133] The function of the above structure will be explained. Before performing observation based on endoscope 12, the operating part 12b of endoscope 12 is held on the hanger 30. The doctor or medical personnel using the endoscope hold the handle 104 of the endoscope sterilization device 100 ( Figure 15 In the process, the flexible part 12a is inserted into the through insertion part 101, held by the physician D. Next, the power switch 105 of the endoscope sterilization device 100 is operated to turn on the power. Then, the sterilization light sources 102 and 103 irradiate at least a portion of the flexible part 12a inserted into the through insertion part 101 with sterilizing ultraviolet light. While maintaining this state, the physician or medical personnel hold the handle 104 of the endoscope sterilization device 100, for example, by gradually lowering it from the base to the tip or gradually raising it from the tip to the base. When manually moving the endoscope sterilization device 100, the entire flexible part 12a can be sterilized by irradiating it with sterilizing ultraviolet light from the sterilization light sources 102 and 103. By irradiating the entire flexible part 12a with ultraviolet light, a high sterilization effect can be obtained.

[0134] [Sixth Implementation]

[0135] In the fifth embodiment described above, an endoscope sterilization device was illustrated for sterilizing the entire flexible portion 12a only by manual movement. However, the present invention is not limited to this, and the method of sterilization can be changed between the insertion of the tip 12d and the method of sterilizing the entire flexible portion 12a by manual movement. In the sixth embodiment described below, an endoscope sterilization device and endoscope sterilization system are shown, which, in a fixed state, can be configured to sterilize by inserting the tip 12d, and in a user-held state, can be configured to sterilize the entire flexible portion 12a by manual movement.

[0136] like Figure 17 and Figure 18 As shown, the endoscope sterilization device 110 consists of a sterilization device body 111 and a cover member 112. The sterilization device body 111 has the same structure as the endoscope sterilization device 100 of the fifth embodiment described above, including an insertion part 101, sterilization light sources 102 and 103, a holding part 104, a light source control part, and a power switch 105, therefore the same reference numerals are used and the description is omitted. The endoscope sterilization device 110 is used together with the endoscope trolley 20. The endoscope sterilization device 110 and the endoscope trolley 20 constitute the endoscope sterilization system of the claims. In addition, the structure of the endoscope trolley 20 is the same as that of the first embodiment described above, and the description is omitted.

[0137] The covering member 112 is formed in a U-shape corresponding to the peripheral portion 106 of the sterilization device body 111. By supplementing the open portion in the other covering member or peripheral portion 106 with one of the covering members or peripheral portions 106, a receiving portion 113 is formed (see reference). Figure 14 A raised portion 112B is formed on the inner surface of the opposing straight portions 112A of the covering member 112. For example, by fitting the raised portion 112B between the straight portions 106A of the peripheral portion 106, the covering member 112 and the insertion portion 101, i.e., the sterilization device body 111, can be integrated.

[0138] When the covering member 112 and the insertion part 101 are integrated, the receiving part 113 is formed as a bottomed cylindrical shape having an opening 113A, a peripheral part 113B, and a rear surface part 113C. The peripheral part 113B is formed as a quadrilateral cylindrical shape constituting the upper and lower surfaces and left and right sides of the receiving part 113. The rear surface part 113C blocks the rear end of the peripheral part 113B. The rear surface part 113C corresponds to the bottom part in the claims.

[0139] The interior of the receiving portion 113, surrounded by the peripheral surface portion 113B and the rear surface portion 113C, is the sterilization space 106B of the insertion portion 101. This space is irradiated with sterilizing ultraviolet light by the sterilization light sources 102 and 103 located in the sterilization device body 111. The sterilization space 106B is formed to be at least larger than the outer diameter and axial length of the front end portion 12d, and is capable of accommodating the front end portion 12d. The opening 113A is a circular through hole located on the front surface of the peripheral surface portion 113B, with an inner diameter at least larger than the outer diameter of the flexible portion 12a. At least a portion of the flexible portion 12a can be inserted into the sterilization space 106B from the outside of the receiving portion 113 through the opening 113A.

[0140] The function of the above structure will be explained. With the cover member 112 and the insertion part 101 integrated, the endoscope sterilization device 110 includes a receiving part 113 and sterilization light sources 102 and 103. Therefore, it can be used as a fixed endoscope sterilization device mounted on an endoscope trolley 20, similar to the endoscope sterilization device 18 of the first embodiment described above. That is, before performing observation based on the endoscope 12, the operating part 12b of the endoscope 12 is held behind the hanger 30, and the doctor or medical personnel using the device operate the power switch 105 of the endoscope sterilization device 110 to turn on the power. Then, the front end portion 12d is inserted from the opening 113A into the interior of the receiving part 113, i.e., the sterilization space 106B. Ultraviolet light is irradiated from the sterilization light sources 102 and 103 onto at least a portion of the flexible part 12a, including the front end portion 12d. High sterilization effect can be achieved by reliably sterilizing the front end 12 days by irradiating with ultraviolet light.

[0141] On the other hand, when the covering part 112 and the insertion part 101 are separated, the sterilization device body 111 has the same structure as the endoscope sterilization device 100 of the fifth embodiment described above. Therefore, when the doctor or medical personnel hold the holding part 104 of the sterilization device body 111 and move the sterilization device body 111 manually, the entire soft part 12a can be sterilized by irradiating the soft part 12a with sterilization ultraviolet light based on sterilization light sources 102 and 103.

[0142] As described above, by simply attaching and detaching the cover part 112, it is possible to switch between sterilizing the front end 12d by insertion and sterilizing the entire soft part 12a by manual movement.

[0143] Furthermore, in the above-described embodiments 4 to 6, a plurality of sterilization light sources are provided in the insertion portions 82 and 101. However, the present invention is not limited to this. For example, a reflective material may be provided instead of at least a portion of the plurality of sterilization light sources to reflect ultraviolet light from the sterilization light sources. In addition, in the 6th embodiment, a reflective material may also be provided inside the covering member 112 (at a position opposite to the sterilization space 106B).

[0144] [3rd Variation]

[0145] In the variations described below, it is possible to modify the method of sterilization for endoscopic devices in addition to the structures of embodiments 5 and 6. For example... Figure 19 As shown in (A), the insertion part 101 is provided with a rotating shaft 115 that rotates the straight part 106A outward by 90°.

[0146] like Figure 19 As shown in (B), by rotating the straight portion 106A outward by 90°, the opposing straight portions 106A become a straight line, resulting in a state where all the sterilization light sources 102 and 103 are arranged on one side. Therefore, it can also be used for sterilizing endoscopic devices with a surface area larger than the flexible portion 12a of the endoscope 12, such as the light source device 14 or the processor device 15. Figure 20 This example illustrates an application of the sterilization device body 111 of this modified embodiment for sterilizing the processor device 15. The user can hold the handle 104, positioning the sterilization light sources 102 and 103 opposite the operation panel 15A of the processor device 15 and irradiating them with ultraviolet light. This allows for sterilization of large-area components such as the operation panel 15A. Furthermore, this is not a limitation; the sterilization device body 111 of this modified embodiment can also be used for sterilizing operating switches 15B, etc.

[0147] [Seventh Implementation]

[0148] In the above-described embodiments 4 to 6, an endoscope sterilization device and an endoscope sterilization system are illustrated, which sterilize the entire flexible part 12a by moving relative to the flexible part 12a. However, the present invention is not limited to this, and the entire flexible part 12a can also be sterilized by covering it. Figures 21-23 In the endoscope sterilization system 120 of this embodiment shown, a hanger 122 and an endoscope sterilization device 121 for sterilizing the soft part 12a are integrally provided to sterilize the entire soft part 12a.

[0149] like Figure 21 As shown, the hanger 122, which is integrally formed with the endoscope sterilization device 121, is mounted on the endoscope trolley 123. Like the hanger 30 provided on the endoscope trolley 20 in the first embodiment described above, it has a notch or groove (in...). Figure 23 In the example shown, a notch 122A is provided, which allows the endoscope 12 to be suspended by holding the operating part 12b of the endoscope 12 within the notch or slot. The hanger 122 is mounted on the upper end of the right-side support 23 via the hanger bracket 31. When the operating part 12b is held in the hanger 122, the downward direction of the flexible part 12a, which droops due to its own weight, is parallel to the vertical direction Z.

[0150] In this embodiment, an endoscope trolley 123 is provided with two endoscope sterilization devices 121 and hangers 122. However, the number of endoscope sterilization devices 121 and hangers 122 is not limited to two. Appropriately, a number of hangers 30 are provided that correspond to the purpose of use of the endoscope 12 and the size of the endoscope trolley 123 and the hanger support 31. When the operating part 12b is held on the hanger 122, the endoscope sterilization device 121 is located in the downward direction where the flexible part 12a hangs down due to its own weight.

[0151] Furthermore, in the endoscope trolley 123, a hanger 122, which is integrally formed with the endoscope sterilization device 121, is installed on the right support column 23, and a hanger 30, identical to that of the endoscope trolley 20 in the first embodiment, is installed on the left support column 24 via a hanger bracket 31. Apart from this, the endoscope trolley 123 is identical to the endoscope trolley 20 in the first embodiment; therefore, identical components are labeled with the same symbols and descriptions are omitted.

[0152] like Figure 22As shown, the endoscope sterilization device 121 includes a housing portion 125, a sterilization light source 126, and a power switch 127. The housing portion 125 has at least a peripheral portion 128 extending in the vertical direction Z, which houses the flexible portion 12a of the endoscope 12. Furthermore, the endoscope sterilization device 121 has a curved portion 129 that smoothly connects the hanger 122 and the peripheral portion 128. The power switch 127 is provided, for example, on the side of the curved portion 129.

[0153] The peripheral surface 128 has a groove 128A formed along the vertical direction Z (reference). Figure 23 The groove-shaped part is positioned opposite the outer periphery of the flexible part 12a, which droops due to its own weight, while the operating part 12b is held in the hanger 122.

[0154] A sterilization light source 126 is arranged along the vertical direction Z inside the groove 128A of the peripheral surface 128. The sterilization light source 126 irradiates the soft part 12a with sterilization light. Additionally, in Figure 22 and Figure 23 In this embodiment, multiple sterilization light sources 126 are disposed on a peripheral surface 128, but it is not limited to this; only one elongated sterilization light source 126 may be disposed on a peripheral surface 128. In addition, the sterilization light source 126 uses the same ultraviolet light source as the sterilization light sources 42 and 43 in the first embodiment described above, but a cylindrical excimer lamp is preferred as the sterilization light source 126.

[0155] The function of the above structures will be explained. For example... Figure 23 As shown, before performing observation based on the endoscope 12, with the operating part 12b of the endoscope 12 held in the hanger 122, the endoscope sterilization device 121 is positioned in the downward direction where the flexible part 12a droops due to its own weight, as shown above. Therefore, the doctor or medical personnel using the endoscope sterilization device 121 can easily insert the flexible part 12a into the slot 128A of the endoscope sterilization device 121. Then, the doctor or medical personnel operate the power switch 127 of the endoscope sterilization device 121 to turn on the power. By irradiating with ultraviolet light, the entire flexible part 12a is reliably sterilized, achieving a high sterilization effect.

[0156] Furthermore, after use, the endoscope 12 can hold the operating part 12b in the hanger 30 mounted on the left support column 24. Since the hanger 30 is located separately from the endoscope sterilization device 121 located on the right support column 23, bodily fluids and other contaminants will not adhere to the endoscope sterilization device 121, thus keeping the endoscope sterilization device 121 clean.

[0157] [4th Variation]

[0158] Furthermore, in the seventh embodiment described above, the entire endoscope sterilization device 121 is formed in a groove shape, but it is not limited to this; it can be formed as follows: Figure 24 As shown, the upper part of the endoscope sterilization device 121 is formed in a groove shape, and the lower part is formed in a cylindrical shape. Specifically, the lower part 128B (at least the portion accommodating the front end 12d) of the peripheral surface 128 of the endoscope sterilization device 121 is formed in a cylindrical shape with a quadrilateral cross-section, which allows the flexible part 12a to be inserted. This allows the outer peripheral surface of the flexible part 12a to be covered, thereby further improving the sterilization effect. Furthermore, the lower part 128B is not limited to a cylindrical shape with a quadrilateral cross-section; it can be any shape that allows the flexible part 12a to be inserted, for example, it can be cylindrical.

[0159] In the above embodiments or their variations, an endoscope trolley is exemplified as an endoscope holding device, but it is not limited to this; the endoscope holding device may also be an endoscope bracket with an operating section for holding the endoscope. Furthermore, in the above embodiments or their variations, the reflective material disposed inside the housing may be, for example, a thin metal sheet with a mirror-like surface or a component with an electroplated surface.

[0160] Furthermore, in the above embodiments, the endoscope 12 combined with the endoscope sterilization device or endoscope sterilization system of the present invention is not specific, but it can be any endoscope with an insertion part, such as a bronchoscope, an upper digestive tract endoscope or a lower digestive tract endoscope.

[0161] In the above embodiments, the hardware structure of the processing unit (processing unit) of the light source control unit that performs various processes is as shown below. Among the various processors, there are general-purpose processors that execute software (programs) to function as various processing units, such as CPUs (Central Processing Units), GPUs (Graphics Processing Units), FPGAs (Field Programmable Gate Arrays), and other processors whose circuit structure can be changed after manufacturing, such as Programmable Logic Devices (PLDs), and processors with circuit structures specifically designed for performing various processes, such as dedicated circuits.

[0162] A processing unit can be constructed from one of these various processors, or from a combination of two or more processors of the same or different types (e.g., multiple FPGAs, combinations of CPUs and FPGAs, or combinations of CPUs and GPUs). Furthermore, a single processor can also constitute multiple processing units. Examples of a single processor constituting multiple processing units include: first, computers such as client and server computers, where a single processor is composed of a combination of one or more CPUs and software, functioning as multiple processing units; and second, system-on-chip (SoC), where a processor implements the overall functionality of a system containing multiple processing units through a single integrated circuit (IC) chip. Thus, various processing units are constructed as hardware structures using one or more of the aforementioned processors.

[0163] Moreover, the hardware structure of these various processors, more specifically, is a circuit composed of semiconductor elements and other circuit components.
