Description

[Technical Field]

[0001] The present invention relates to an endoscope, and more particularly to a structure for operating an erection stand. [Background technology]

[0002] An endoscope includes an insertion section that is inserted into a body cavity of a subject, and an operating section that is connected to the insertion section. The operating section is provided with an operating lever, an operating knob, etc. An operator operates the operating lever, etc. to remotely control a follower provided in the insertion section.

[0003] Patent Document 1 describes a tool lifter that is provided in the insertion section of an endoscope and lifts up a guide catheter protruding from a channel opening. The lifting wire connected to the tool lifter is led to an operating section through a guide pipe and a guide tube that are inserted into the insertion section, and is connected to a lifter operating mechanism.

[0004] The elevator operating mechanism includes a wire fixing member to which the base end of the elevator wire is fixed, and a link member to which the base end of the wire fixing member is fixed. The link member is provided on the guide member so as to be reciprocable in the axial direction of the operating unit.

[0005] Patent Document 1 describes the structure of a lifting platform operating mechanism in which the opposing guide surfaces of a guide member are provided with unevenly formed concave-convex surfaces, and the link member is provided with a protrusion that engages with the uneven surfaces.The document also describes that when the lifting operation knob is operated to raise the lift beyond the first lifting range to the second lifting range, the engagement between the protrusion of the link member and the uneven surface of the guide member transmits a foreign body sensation to the surgeon, allowing the surgeon to recognize that the safe lifting range for the miniscope or the like has been exceeded.

[0006] Patent Document 2 describes an endoscope that allows the state of the elevator to be known from outside. The endoscope described in this document incorporates a fixing mechanism that releasably fixes the rotation axis of the knob at a position where the elevator is collapsed in the operation unit body.

[0007] The fixing mechanism fixes the rotary shaft by engaging a hole in the rotary shaft with a ball that elastically engages with the hole. When the knob is turned with a certain amount of force, the hole and ball are disengaged, allowing the rotary shaft to be operated. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-116777 [Patent Document 2] Japanese Utility Model Application Publication No. 57-32001 Summary of the Invention [Problem to be solved by the invention]

[0009] For example, in a duodenoscope, when inserting a guidewire, an endoscope tube, or the like into the duodenal papilla, it is necessary to fine-tune the standing position of the stand. The standing position is adjusted by operating an operating lever or the like of the operating unit. When the standing position is adjusted, the movement of the guidewire or the like is displayed on a monitor screen so that the operator can monitor it. Meanwhile, it is desirable to notify the operator of a rough indication of the operating amount, such as the operating pitch of the operating lever.

[0010] The endoscope described in Patent Document 1 allows the user to know the state of the treatment instrument stand by the feel of the hand operating the operating part due to the clicking sensation and resistance when operating the operating part. The operator is notified whether the safe lifting range of the lifting lever or the like has been exceeded, but the operator is not notified of an indication of the amount of operation, such as the operating pitch of the operating part.

[0011] The endoscope described in Patent Document 2 notifies the operator that the control knob is locked by the feel of the control knob, but does not notify the operator of an indication of the amount of operation, such as the operation pitch of the control knob.

[0029] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and accompanying drawings, identical components are designated by the same reference numerals, and duplicate explanations will be omitted. Furthermore, when multiple components are exemplified in the following embodiments, it can be interpreted as including at least one of the multiple components.

[0030] [Overall structure of the endoscope] FIG. 1 is a diagram showing the overall configuration of an endoscope according to this embodiment.

[0031] 1, an endoscope 1 includes an insertion section 2 that is inserted into a subject, and an operation section 3 that is connected to the base end of the insertion section 2 and operated by an operator. In the embodiment, a side-viewing endoscope used as a duodenoscope is exemplified.

[0032] Hereinafter, when describing the configuration of each part of the endoscope 1, for convenience of explanation, an X, Y, Z three-dimensional Cartesian coordinate system will be used. The Z direction in the figure indicates the up-down direction, with the Z(+) direction side indicating the upper side and the Z(-) direction side indicating the lower side. The X direction in the figure indicates the direction perpendicular to the Z direction, with the X(+) direction side indicating the right side and the X(-) direction side indicating the left side. The Y direction in the figure indicates the direction perpendicular to both the Z direction and the X direction, with the Y(+) direction side indicating the distal end side and the Y(-) direction side indicating the proximal end side. Note that each of the above directions refers to the direction when the surgeon views the insertion portion 2 from above when holding the operation unit 3 of the endoscope 1.

[0033] <Insertion part 2> The insertion section 2 of the endoscope 1 is inserted into the subject's mouth, then further inserted through the esophagus and stomach into the duodenum, whereby a procedure such as an examination or treatment of the duodenum is performed using a treatment tool inserted inside the insertion section 2.

[0034] Examples of treatment tools include biopsy forceps having a cup at the tip that can collect biological tissue, an EST (Endoscopic Sphincterotomy) knife, and an imaging tube.

[0035] The insertion section 2 has a longitudinal axis Ax and, from its base end to its tip end, has a flexible section 5, a bending section 6, and a tip section 7. The longitudinal axis Ax direction and the Y direction are the same direction. The longitudinal axis Ax direction is an example of the longitudinal axis direction in the present disclosure.

[0036] The flexible section 5 occupies the majority of the proximal end of the insertion section 2 and is made up of, for example, a metal spiral tube and net (not shown), the outer periphery of which is further covered with a resin tube. The flexible section 5 has flexibility that allows it to bend in any direction, and when the insertion section 2 is inserted into a body cavity, it bends along the insertion path into the body cavity.

[0037] The bending portion 6 has a cylindrical body with multiple angle rings connected to each other so that they can swing, and the outer periphery of this cylindrical body is covered with a mesh body woven with metal wires, and the outer periphery of that is covered with rubber angle rubber. In addition, multiple wires extend from the angle knobs 8 and 9 of the operation unit 3 to the bending portion 6, and the tips of these wires are fixed to the tips of the cylindrical body. As a result, the bending portion 6 is bent in the up-down direction (Z direction) and left-right direction (X direction) in response to the rotation of the angle knobs 8 and 9.

[0038] The tip portion 7 will be described in detail with reference to FIG. 2 and subsequent figures, and includes a tip member 20 and a tip cap 200 (see FIG. 2) that is detachably attached to the tip member 20.

[0039] The tip member 20 is provided at the tip portion 7 and is made of a corrosion-resistant metal material. The tip cap 200 is made of an elastic material, for example, silicone rubber.

[0040] <Operation unit 3> As shown in FIG. 1, the operation unit 3 includes angle knobs 8 and 9 for bending the bending portion 6, and an air supply It has a water supply button 10, a suction button 11, a lever 12 for raising the device, and a treatment tool introduction port 13.

[0041] The air and water supply button 10 is an operating button for supplying air and water from the air and water supply nozzle 14 (see Figure 2) at the tip 7 toward the observation window 16, the illumination window 18, etc. via an air and water supply channel (not shown) inserted inside the insertion section 2.

[0042] The suction button 11 is an operation button for suctioning bodily fluids and the like through a treatment tool insertion channel 38 (see FIG. 4) inserted inside the insertion portion 2.

[0043] The raising operation lever 12 is a lever that receives an operation for operating a raising stand 36 (see FIG. 2) provided at the distal end portion 7. The raising operation lever 12 is one of the components of the treatment tool raising mechanism, and is an example of a raising operation member of the present disclosure.

[0044] The treatment tool introduction port 13 is an opening that communicates with the treatment tool insertion channel 38 and allows the surgeon to introduce a treatment tool, etc. The treatment tool introduced from the treatment tool introduction port 13 passes through the treatment tool insertion channel 38 and is guided to the distal end portion 7.

[0045] A universal cord 4 is connected to the operation unit 3, and this universal cord 4 is connected to an image processing device and a light source device (not shown). A monitor device (not shown) is connected to the image processing device via a cable.

[0046] The above is the overall structure of the endoscope 1. The structure of the tip portion 7 will now be described.

[0047] <Tip 7> Fig. 2 is an enlarged perspective view of the tip portion as viewed from the Z(+) direction side. Fig. 2 shows a state in which the tip cap 200 is attached to the tip member 20. As shown in Fig. 2, when the tip cap 200 is attached to the tip member 20, the tip cap 200 has an upper opening 202 that communicates with an opening 24 on the Z(+) direction side of the elevator housing section 22 described below.

[0048] The upper opening 202 is provided on the Z(+) direction side and is formed to a size that exposes the standing platform storage section 22 (opening 24), the tip of the air / water nozzle 14, the observation window 16, the illumination window 18, and the guide wire fixing section 50 (described later). Note that the symbol 200B indicates the tip of the tip cap 200.

[0049] Figure 3 is a perspective view showing the state in which the tip cap has been removed from the tip member of Figure 2. The tip cap 200 is configured in a substantially cylindrical shape to accommodate the tip member 20. The tip cap 200 also has an upper opening 202 for opening the opening 24 of the erector housing section 22, a tip end opening 204 for opening the tip opening on the Y(+) direction side of the erector housing section 22, a base end opening 206 for attaching the tip cap 200 to the tip member 20, and an engagement groove 208.

[0050] The tip opening 204 is connected to the upper opening 202 and is formed as an air vent opening to prevent the body cavity wall from being sucked onto the upper opening 202 during the suction operation of the endoscope 1. The base opening 206 is an opening for inserting the tip member 20.

[0051] 4 is a cross-sectional view of the distal end portion 7 shown in FIG. 2 cut along the ZY plane. The distal end cap 200 has an engagement groove 208 and a flat portion 210 on its inner circumferential surface on the base end side. The engagement groove 208 is provided around the entire inner circumferential surface of the distal end cap 200. The flat portion 210 is The flat portion 210 is provided on the Z(+) side surface of the inner circumferential surface of the tip cap 200, closer to the base end (Y(-) side) than the engagement groove 208. The flat portion 210 is substantially parallel to the XY plane. Here, substantially parallel includes parallel, and may also include substantially parallel, which can be considered to be parallel even if it is not parallel.

[0052] The engagement groove 208 engages with the flange portion 30 protruding from the outer peripheral surface of the base portion 28 of the tip member 20. This allows the tip cap 200 to be attached to the tip member 20. Furthermore, when the tip cap 200 is attached to the tip member 20, the flat portion 210 comes into contact with the flat portion 78 provided on the insulating ring 70.

[0053] 3, the tip member 20 has a first wall portion 32 and a second wall portion 34 that face each other in the X direction. The first wall portion 32 is disposed on the X(-) direction side, and the second wall portion 34 is disposed on the X(+) side.

[0054] In addition, a stand accommodating section 22 for accommodating a stand 36 is provided between the first wall section 32 and the second wall section 34 in the X direction. This stand accommodating section 22 is arranged in parallel with the first wall section 32 and the second wall section, and is formed as a slit-like space along the Y direction.

[0055] The distal end of a treatment tool insertion channel 38 (see FIG. 4) is connected to the raising table housing section 22. This treatment tool insertion channel 38 is inserted into the insertion section 2 (see FIG. 1), and its proximal end is connected to the treatment tool introduction port 13 of the operation section 3. As a result, a treatment tool introduced from the treatment tool introduction port 13 is guided through the treatment tool insertion channel 38 to the raising table housing section 22. The direction of the treatment tool guided to the raising table housing section 22 is changed by the raising table 36. The reference symbol 36A denotes a guide surface of the raising table 36.

[0056] Fig. 5 is a perspective view of the tip member 20 as seen from the Y(+) direction side. Fig. 5 illustrates a state in which the cover attached to the second wall portion 34 has been removed and the tip cap 200 has been removed from the tip member 20.

[0057] <First wall part 32> The first wall 32 has an observation window 16 and an illumination window 18. An imaging unit and an illumination unit are provided inside the first wall 32. The imaging unit has an imaging optical system disposed inside the observation window 16 and a CMOS (complementary metal oxide semiconductor) or CCD (charge coupled device) imaging element. The imaging element is connected to an image processing device via a signal cable inserted inside the insertion portion 2. An imaging signal of the subject image obtained by this imaging unit is input to the image processing device via the signal cable and displayed as the subject image on a monitor connected to the image processing device via a cable.

[0058] The illumination unit has an illumination lens installed inside the illumination window 18 and a light guide arranged so that its tip faces the illumination lens. The light guide is inserted inside the insertion unit 2, and its base end is connected to the light source device. As a result, illumination light from the light source device is transmitted via the light guide and emitted from the illumination window 18.

[0059] <Second wall part 34> The second wall portion 34 is provided with a recessed lever accommodating chamber 44 that accommodates the lever 42. Of the two wall surfaces of the second wall portion 34 that face each other in the X direction, the lever accommodating chamber 44 is provided on the wall surface opposite the wall surface that faces the elevator accommodating section 22.

[0060] A rotation shaft 42A is provided at one end of the lever 42 in the lever accommodating chamber 44. The rotation shaft 42A penetrates the second wall portion 34 in the X direction and is connected to the stand 36. The other end of the lever 42 is connected to an operation wire 46. The operation wire 46 is inserted into the insertion section 2 (see FIG. 1) and connected to the lever 12 for raising operation of the operation section 3.

[0061] Therefore, when the surgeon operates the raising operation lever 12, the operation wire 46 is pushed or pulled, and the lever 42 swings in conjunction with this pushing and pulling operation. As a result, the raising base 36 swings around the rotation axis 42A as the swing axis, changing its position between an upright position and a reclined position. Here, the lever 42 having the rotation axis 42A, the operation wire 46, and the raising operation lever 12 constitute a treatment tool raising mechanism. The lever housing chamber 44 is sealed by a cover (not shown). The operation wire 46 is an example of the raising operation wire of the present disclosure.

[0062] 〈Standing platform 36〉 The erector 36 is provided on the distal end member 20 and is housed in the erector housing portion 22. The erector 36 is attached to the second wall portion 34 via a rotation shaft 42A so as to be able to swing freely. The erector 36 is driven by the treatment tool erecting mechanism to perform erecting and lowering movements.

[0063] The elevator 36 also has a guide surface 36A shown in Fig. 2. The guide surface 36A is formed on a surface that faces the Z(+) side when the elevator 36 is in the reclined position. This guide surface 36A is a surface for guiding a treatment tool, and is formed in a generally U-shape that is recessed inward from the base end, which is the swing end of the elevator 36, to the tip end.

[0064] When the treatment tool erection mechanism erects the stand 36, the treatment tool led into the stand housing section 22 is guided by the guide surface 36A of the stand 36 in the direction toward the opening 24 of the stand housing section 22, and is led out through the upper opening 202 of the tip cap 200. In addition, by adjusting the erection angle of the stand 36 with the treatment tool erection mechanism, the lead-out direction of the treatment tool can be changed.

[0065] <Guidewire fixing portion 50> A guide wire fixing portion 50 is provided on the base portion 28. This guide wire fixing portion 50 protrudes from the distal wall portion of the base portion 28 toward the elevator housing portion 22 in the Y(+) direction.

[0066] The guidewire fixing portion 50 is configured as a convex portion tapered in the Y(+) direction. In other words, the guidewire fixing portion 50 is configured in the shape of a substantially trapezoidal cube with the distal end wall portion as the bottom surface.

[0067] When the erector 36 is raised to the maximum erect position, the guidewire (not shown) guided from the treatment tool insertion channel 38 to the erector housing section 22 is sandwiched and fixed between the convex tip of the guidewire fixing section 50 and the concave guide surface 36A of the erector 36. The guidewire fixing section 50 is arranged alongside the air / water supply nozzle 14 in the X direction.

[0068] <Insulation Ring 70> The base 28 of the tip member 20 is configured in a substantially cylindrical shape along the Y direction, and an annular insulating ring 70 is attached to the outer periphery of the base 28. This insulating ring 70 is made of an insulating material such as plastic or ceramic.

[0069] The insulating ring 70 has a flange portion 72 that protrudes radially outward along its outer surface, a cap mounting portion 74 that is positioned further distal than the flange portion 72, and a curved portion mounting portion 76 that is positioned further proximal than the flange portion 72.

[0070] The cap attachment portion 74 has a flat portion 78 and an arc portion 80 on its outer circumferential surface. The flat portion 78 is provided on the Z(+) side of the outer circumferential surface, and is formed at a position (position on the Z(-) side) lower than the flange portion 30 of the base portion 28. This flat portion 78 is approximately parallel to, for example, the XY plane.

[0071] The cap attachment portion 74 is configured so that its inner diameter is larger than the outer diameter (diameter) of the base portion 28. The cap attachment portion 74 is fitted onto the base portion 28 from the base end side to the tip end side of the base portion 28, and the base end of the cap attachment portion 74 abuts against the base end side surface of the flange portion 30 of the base portion 28.

[0072] As a result, the cap attachment portion 74 is attached to the base portion 28, and the insulating ring 70 is attached to the tip member 20. In this case, the flat portion 78 and the arc portion 80 of the insulating ring 70 are disposed on the base end side of the flange portion 30.

[0073] 5, the distal end cap 200 is attached to the distal end member 20. In this case, the distal end cap 200 is fitted onto the distal end member 20 from the distal end side to the proximal end side of the distal end member 20, and the proximal end 200A of the distal end cap 200 is brought into contact with the distal end side surface 72A of the flange portion 72 of the insulating ring 70.

[0074] 4, the engagement groove 208 of the tip cap 200 engages with the flange portion 30 of the tip member 20, and the flat portion 210 of the tip cap 200 abuts against the flat portion 78 of the insulating ring 70. As a result, the tip cap 200 is attached to the tip member 20, and the metal tip member 20 is covered by the insulating tip cap 200 and the insulating ring 70.

[0075] With this configuration, according to the endoscope 1 of this embodiment, the insulation of the tip portion 7 can be ensured by the tip cap 200 and the insulating ring 70. Furthermore, the engagement between the flange portion 30 and the engagement groove 208 can prevent the tip cap 200 from slipping off from the tip member 20 in the Y(+) direction. Furthermore, the abutment between the flat portion 78 and the flat portion 210 can prevent the tip cap 200 from shifting relative to the tip member 20 in the direction around the longitudinal axis Ax.

[0076] The base end 200A of the tip cap 200 and the flange portion 72 of the insulating ring 70 each have approximately the same outer diameter (diameter). As a result, when the tip cap 200 is attached to the tip member 20, the tip cap 200 and the insulating ring 70 are connected without any steps on their outer circumferential surfaces.

[0077] Furthermore, if the engagement groove 208 is not fully engaged with the flange portion 30 and the distal end cap 200 is incompletely attached to the distal end member 20, for example, if the distal end cap 200 is attached with the base end 200A of the distal end cap 200 abutting the flange portion 30, a part of the distal end cap 200 (for example, a part located on the base end side of the air / water supply nozzle 14) will be within the observation field of the imaging unit. In this case, a part of the distal end cap 200 will appear black on the observation screen displayed on the monitor device. This will notify the surgeon of the incomplete attachment.

[0078] <Operation explanation of the stand 36> Figure 6 is an explanatory diagram of the operation of the elevator. Figure 6 shows the distal end member 20 visualized in a see-through manner from the side of the second wall portion 34. Hereinafter, the reference numerals used in Figures 2 to 5 will be omitted as appropriate.

[0079] The stand 36 has a tilt angle of 0 degrees or more and 100 degrees or less when the stand angle of the stand 36 is 0 degrees. 6 shows the stand 36 when the standing angle is 25 degrees and when the standing angle is 100 degrees. In addition, the figure shows the stand 36 at standing angles of 25 degrees, 45 degrees, and 75 degrees using solid lines.

[0080] [Example of a treatment tool erection mechanism] Fig. 7 is an explanatory diagram showing a structural example of the treatment tool erection mechanism. The figure illustrates a structural example of the treatment tool erection mechanism 300 on the side of the operation unit 3. Fig. 7 is a see-through view of the housing of the operation unit 3 illustrated in Fig. 1 etc., visualizing the internal structure from the side where the erection operation lever 12 is installed. Note that the erection operation lever 12 is not shown in Fig. 7.

[0081] A link mechanism 304 and a linear motion mechanism part 313 that constitute the treatment tool erection mechanism 300 are provided inside the operation part 3. The link mechanism 304 includes a rotary drum 307, a crank member 308, and a slider 309.

[0082] The rotating drum 307 is rotatably supported on the base plate 302 by a rotating shaft 307A extending in a direction perpendicular to the base plate 302. The standing operation lever 12 shown in Fig. 1 etc. is attached to the rotating shaft 307A. In addition, one end of a crank member 308 is rotatably connected to the rotating drum 307.

[0083] A slider 309 is connected to the other end of the crank member 308 so as to be rotatable relative to the crank member 308. The slider 309 is connected to one end of a connecting portion 305. The other end of the connecting portion 305 is connected to a guide tube 311. The slider 309 is supported by the connecting portion 305 and the guide tube 311 so as to be slidable in the direction of the longitudinal axis Ax shown in FIG. 1. The connecting portion 305 connects the slider 309 to the base end of the operating wire 46. The longitudinal axis Ax may be referred to as the wire axis direction.

[0084] In the treatment tool erection mechanism 300 having such a structure, the slider 309 and the connection part 305 slide in the direction of the longitudinal axis Ax in response to the rotation operation of the erection operation lever 12. The direction of the longitudinal axis Ax includes a first direction in which the operation wire 46 is pushed toward the distal end side of the insertion section 2 and a second direction in which the operation wire 46 is pulled toward the proximal end side of the insertion section 2.

[0085] The linear motion mechanism 313, which includes the slider 309, the connection part 305, and the guide tube 311, is provided with a notification part 312 having a structure for notifying operation pitch information indicating the pitch of the operation of the stand 36 caused by the operation of the stand operation lever 12. The operation pitch information indicating the pitch of the operation of the stand 36 is an example of interval information indicating the operation interval of the stand of the present disclosure.

[0086] [Example of the alarm unit] Fig. 8 is a schematic diagram showing an example of the configuration of the notification unit. Fig. 8 shows an example of a component that functions as the notification unit 312 shown in Fig. 7. The notification unit 312 has a structure that notifies operation pitch information that indicates the pitch of the operation of the erection platform 36 caused by the operation of the erection operation lever 12. This notification unit 312 includes a slider mechanism 314 and a contact member 318.

[0087] One end 314A of the slider mechanism 314 is connected to the crank member 308. Like the slider 309 shown in Fig. 7, the slider mechanism 314 is rotatably connected to the crank member 308 and is connected so as to be able to move forward and backward in the direction of the longitudinal axis Ax in response to the rotation of the crank member 308. The direction of movement of the slider mechanism 314 is indicated by a horizontal double-headed arrow.

[0088] The other end 314B of the slider mechanism 314 is connected to the base end of the operation wire 46. The tip of the operation wire 46 is connected to the stand 36 via the lever 42 shown in Fig. 5. The slider mechanism 314 and the operation wire 46 may be provided as separate members (not shown).

[0089] The operation wire 46 is biased in a direction perpendicular to the longitudinal axis Ax by the biasing unit 317. For example, the direction in which the operation wire 46 is biased is shown using a downward arrow. The operation wire 46 is biased in the Z(-) direction shown in FIG. 1 etc.

[0090] The slider mechanism 314 has an uneven surface 314C on which the uneven structure 316 is formed. The uneven surface 314C may be any surface of the slider mechanism 314 that extends in the direction of the longitudinal axis Ax. The uneven structure 316 may have a length in the direction of the longitudinal axis Ax that corresponds to the entire stroke of the operation wire 46, or may have a length less than the entire stroke of the operation wire 46. The slider mechanism 314 may have a plurality of uneven surfaces 314C.

[0091] Slider mechanism 314 is supported using a guide portion (not shown). The guide portion includes contact member 318. Contact member 318 is placed on a surface facing uneven surface 314C, and is biased toward uneven surface 314C to come into contact with uneven surface 314C. Although contact member 318 is illustrated as a cylindrical member in FIG. 8, contact member 318 may be a protrusion formed on the surface of a plate-like member that forms the wall of the guide portion.

[0092] The height from the uppermost position to the lowermost position of the uneven structure 316 and the distance from the lowermost surface of the uneven structure 316 to the lowermost position of the contact member 318 can be determined from the perspective of smoothly raising and lowering the stand 36. For example, the height from the uppermost position to the lowermost position of the uneven structure 316 and the distance from the lowermost surface of the uneven structure 316 to the lowermost position of the contact member 318 may be in the range of 0.1 millimeter to 1.0 millimeter. The height from the uppermost position to the lowermost position of the uneven structure 316 and the distance from the lowermost surface of the uneven structure 316 to the lowermost position of the contact member 318 may be the same or different.

[0093] The guide portion may include a plurality of contact members 318 corresponding to the plurality of uneven surfaces 314C, respectively. Note that uneven structure 316 is an example of a plurality of steps formed at intervals corresponding to the spacing information of the present disclosure. Also, uneven surface 314C on which uneven structure 316 is formed is an example of a step portion of the present disclosure.

[0094] As the slider mechanism 314 moves in the direction of the longitudinal axis Ax, vibrations are generated due to contact between the concave-convex structure 316 and the contact member 318. The vibrations are transmitted to the standing operation lever 12 via the crank member 308, and are transmitted to the operator via the standing operation lever 12 as a clicking sensation, a sense of operational resistance, or the like. This allows the notification unit 312 to notify the operator of the standing operation lever 12 of how much the standing operation lever 12 has moved. The notification unit 312 can also notify the operator of the standing operation lever 12 of how much the standing platform 36 has moved.

[0095] The concave-convex structure 316 associates the operation pitch of the erection operation lever 12 with the erection angle pitch of the erection platform 36. The operation pitch of the erection operation lever 12 is determined based on the pitch of one step in the concave-convex structure 316. The erection angle pitch of the erection platform 36 is determined based on the amount of movement of the operation wire 46 by one step in the concave-convex structure 316.

[0096] The operator of the standing operation lever 12 can understand the relationship between the operation pitch of the standing operation lever 12 and the standing angle pitch of the standing platform 36 based on the clicking sensation of the standing operation lever 12 notified by the notification unit 312. The standing angle pitch is an example of the operation interval of the standing platform of the present disclosure.

[0097] The notification unit 312 notifies the user when the raising operation lever 12 is operated by one operation pitch and the operation wire 46 moves by one operation pitch of the raising operation lever 12. The operator of the raising operation lever 12 can grasp the movement state of the guide wire and the endoscope tube guided by the raising platform 36. This makes it easier to operate the raising operation lever 12 when moving the guide wire, etc. to the target site.

[0098] In addition, the amount of operation of the standing operation lever 12 can be specifically and quantitatively instructed to the operator of the standing operation lever 12 using the unit of operation pitch of the standing operation lever 12.

[0099] For example, when the total stroke of the operating wire 46 is 7.5 mm and the erection angle of the erection platform 36 is in the range of 25 degrees to 100 degrees, the movement of the operating wire 46 in response to a change in the erection angle of the erection platform 36 may be set to 0.1 mm increments. This allows the change in the erection angle of the erection platform 36 to be notified in 1-degree increments, which is convenient when fine-tuning the erection angle of the erection platform 36 in 1-degree increments.

[0100] The total stroke of the operating wire 46 is understood as the total stroke of the slider mechanism 314. The movement amount of the operating wire 46 relative to the amount of change in the erection angle of the erection platform 36 is understood as the movement distance of the slider mechanism 314 relative to the amount of change in the erection angle of the erection platform 36. In addition, the amount of change in the erection angle of the erection platform 36 is understood as the rotation angle of the erection platform 36.

[0101] The notification unit 312 may define the number of pitches of the raising operation lever 12 from when the guide wire is displayed on the monitor until it is raised again. For example, the range in which the uneven structure 316 is formed may be defined so that the guide wire is displayed on the monitor at the next pitch after the initial touch.

[0102] The notification unit 312 may define a range in which the uneven structure 316 is formed on the uneven surface 314C so that contact between the uneven structure 316 and the contact member 318 occurs when the erection angle of the erection base 36 is in the range of 45 degrees or more and 75 degrees or less. The notification unit 312 may define a range in which the uneven structure 316 is formed on the uneven surface 314C so as to correspond to the entire operation range of the erection operation lever 12.

[0103] The uneven structure 316 may have different pitches in a first formation region and a second formation region of the uneven surface 314C. For example, a first pitch may be applied to the first formation region of the uneven surface 314C where the standing angle of the stand 36 is between 0 and 45 degrees, and a second pitch different from the first pitch may be applied to the second formation region of the uneven surface 314C where the standing angle of the stand 36 is between 45 and 75 degrees. The second pitch may be smaller than the first pitch. Note that the first pitch is an example of a first interval in the present disclosure, and the second pitch is an example of a second interval narrower than the first interval in the present disclosure.

[0104] The uneven structure 316 may have different heights in a first formation region and a second formation region on the uneven surface 314C. For example, a first height may be applied to the first formation region of the uneven surface 314C where the standing angle of the stand 36 is equal to or greater than 0 degrees and equal to or less than 45 degrees, and a second height different from the first height may be applied to the second formation region of the uneven surface 314C where the standing angle of the stand 36 is greater than 45 degrees and equal to or less than 75 degrees.

[0105] The uneven structure 316 may have different shapes in a first forming region and a second forming region on the uneven surface 314C. For example, a first shape may be applied to the first forming region of the uneven surface 314C where the standing angle of the stand 36 is between 0 and 45 degrees, and a second shape different from the first shape may be applied to the second forming region of the uneven surface 314C where the standing angle of the stand 36 is between 45 and 75 degrees.

[0106] Figure 8 illustrates an example in which a concave-convex structure 316 is formed on the slider mechanism 314 and a contact member 318 is provided on a guide portion that supports the slider mechanism 314, but the slider mechanism 314 may also be provided with a contact member 318 and the concave-convex structure 316 may be formed on the guide portion.

[0107] [Example of uneven surface 314C] 9 is a schematic diagram showing a state in which the concave-convex structure and the contact member are in contact with each other. The concave-convex structure 316 may have a cross section parallel to the longitudinal axis Ax that has an equilateral triangle or an isosceles triangle shape. The concave-convex structure 316 may have multiple convex shapes or multiple concave shapes. The triangles referred to here may have rounded vertices. The vertices of quadrilaterals and polygons may also be rounded.

[0108] The contact member 318 may be sized so that at least a portion of it enters the uneven structure 316. Fig. 9 illustrates a contact member 318 having a size such that half of the contact member 318 enters the uneven structure 316. Fig. 9 also illustrates an uneven structure 316 in which an arrangement pitch P is applied and multiple uneven portions are arranged at equal intervals.

[0109] FIG. 10 is a schematic diagram showing an example of a concave-convex surface on which an asymmetric concave-convex structure is formed. The figure shows a concave-convex structure 316A having an asymmetric cross-sectional shape parallel to the longitudinal axis Ax. This allows the operating feel of the standing operation lever 12 to be different when moving the operation wire 46 in a first direction along the longitudinal axis Ax and when moving the operation wire 46 in a second direction along the longitudinal axis Ax. The cross-sectional shape of the concave-convex structure 316A shown in FIG. 10 is a triangle in which the inclination of the hypotenuse on the first direction side is smaller than the inclination of the hypotenuse on the second direction side. However, the cross-sectional shape may be a triangle in which the inclination of the hypotenuse on the first direction side is smaller than the inclination of the hypotenuse on the second direction side.

[0110] 11 is a schematic diagram showing another specific example of the uneven structure. The uneven structure 316B shown in the figure has a circular cross section parallel to the longitudinal axis Ax. This allows the contact member 318 to come into contact with the uneven structure 316B, which provides a softer feel to the operator of the standing operation lever 12 than when the contact member 318 comes into contact with a sharp step as shown in FIG. 9, etc.

[0111] The uneven structure 316B shown in FIG. 11 may have a cross-sectional shape perpendicular to the longitudinal axis Ax that is an ellipse, or a shape that combines a semicircle or a semiellipse with a rectangle, and the side of the contact member 318 may have a semicircle or semiellipse shape.

[0112] [Modification of treatment tool erection mechanism] Fig. 12 is a perspective view of an operation unit in which a treatment tool erection mechanism according to a modified example is housed. Fig. 12 is a perspective view corresponding to Fig. 7 in which the operation unit 3 is illustrated. Fig. 12 illustrates a state in which the housing on the insertion unit 2 side of the operation unit 3 has been removed, exposing part of the structure of the operation unit 3. Fig. 12 also illustrates a state in which the angle knob 8, angle knob 9, etc. illustrated in Fig. 1 have been removed.

[0113] The treatment tool erecting mechanism 400 according to the modified example includes the erecting operation lever 12, a link mechanism 404, a connecting portion 305, and a guide tube 311, similar to the treatment tool erecting mechanism 300 shown in Fig. 7. The link mechanism 404 includes a rotating drum 307, a crank member 308, and a slider 409. Note that the base plate 302 and the rotating drum 307 shown in Fig. 7 are omitted from Fig. 12.

[0114] 13 is a perspective view showing a structural example of a treatment tool erection mechanism according to a modified example. 2 is a perspective view showing the internal structure of the operation unit 3 shown in FIG.

[0115] 13, a treatment tool standing mechanism 400 has a contact structure 418 formed on a slider 409. The treatment tool standing mechanism 400 has an uneven plate 420 provided at a position facing the contact structure 418. The uneven plate 420 has an uneven structure 416 formed on a surface facing the contact structure 418.

[0116] Fig. 14 is a perspective view of the concave-convex plate shown in Fig. 13 as viewed from below in Fig. 13. The concave-convex plate 420 has a shape that extends in the direction of the longitudinal axis Ax, which is the movement direction of the slider 409, and has a length in the direction of the longitudinal axis Ax that is equal to or greater than the total length of the movement range of the slider 409.

[0117] 13 and 14 show an embodiment in which a contact structure 418 is formed on the slider 409 and a concave-convex structure 416 is formed on the surface of the slider 409 facing the contact structure 418, but the concave-convex structure 416 may be formed on the slider 409 and the contact structure 418 may be formed on the surface facing the concave-convex structure 416.

[0118] [Example of specific slider structure] Fig. 15 is a perspective view showing a structural example of the slider shown in Fig. 13. Fig. 16 is a side view of the slider shown in Fig. 15. Figs. 15 and 16 show a specific structural example of the slider 409 provided in the treatment tool erecting mechanism 400.

[0119] The slider 409 includes a prismatic portion 430 and a cylindrical portion 432. The contact structure 418 is formed in the prismatic portion 430. The prismatic portion 430 is formed with a through-hole 434 that penetrates the prismatic portion 430 in a direction perpendicular to the surface on which the contact structure 418 is formed. A rotation shaft that connects the slider 409 and the crank member 308 is inserted into the through-hole 434.

[0120] The cylindrical portion 432 has a cylindrical shape that extends in a direction perpendicular to the surface on which the contact structure 418 of the rectangular column portion 430 is formed, with the surface 430A as its base end surface being perpendicular to the surface on which the contact structure 418 of the rectangular column portion 430 is formed. The cylindrical portion 432 is connected to the connecting portion 305 shown in FIG.

[0121] 16 illustrates an embodiment in which contact structures 418 are formed on two surfaces that are perpendicular to the base end surface of the cylindrical portion 432 and perpendicular to the surface on which the through-hole 434 is formed. The contact structures 418 may be formed on either of the two surfaces.

[0122] [Specific structural example of uneven plate] Fig. 17 is a perspective view of the concave-convex plate shown in Fig. 13. Fig. 18 is a side view of the concave-convex plate shown in Fig. 17. Figs. 17 and 18 show a specific structural example of the concave-convex plate 420 shown in Fig. 13.

[0123] Fig. 17 is a view of concave-convex plate 420 viewed from the side opposite to the surface on which concave-convex structure 416 is formed. Fig. 18 illustrates the three-dimensional structure of concave-convex structure 416. Concave-convex plate 420 is a flat plate that is long in the direction in which concave-convex structures 416 are arranged, and is provided with structures such as holes and steps that are used when attaching it to the inside of operation unit 3.

[0124] [Actions and Effects of the Endoscope According to the Embodiment] The endoscope 1 according to the embodiment can achieve the following effects.

[0125] <1> The treatment tool erection mechanism 300 that operates the erection table 36 includes a component that functions as a notification unit 312 that notifies the operator of the erection operation lever 12 of operation information of the erection table 36. As a result, the operator of the lever 12 for standing up operation can know the indication of the standing up operation via the notification unit 312.

[0126] <2> The operation information of the stand-up platform 36 is information indicating the stand-up operation that notifies how far the stand-up platform 36 has moved in response to the operation of the stand-up operation lever 12. This allows the operator of the stand-up operation lever 12 to know how far the stand-up platform 36 has moved.

[0127] <3> The movement information of the stand 36 is the number of pitches of the stand operation lever 12. This allows the operator of the stand operation lever 12 to quantitatively know how much the stand 36 has moved.

[0128] <4> The treatment tool erection mechanism 300 includes a concave-convex structure 316 formed on a slider mechanism 314 that slides when the operating wire 46 is advanced or retreated, and a contact member 318 provided on the surface opposite the concave-convex structure 316 of the guide part that supports the slider mechanism 314.

[0129] When the slider mechanism 314 slides to move the operating wire 46 back and forth, vibrations generated between the concave-convex structure 316 and the contact member 318 are transmitted to the standing operation lever 12. This allows the operator of the standing operation lever 12 to feel the vibrations in his or her hand, and enables the operator to grasp the operating state of the standing platform 36 and the operating state of the standing operation lever 12.

[0130] <5> The treatment tool erection mechanism 300 includes a contact member 318 provided on a slider mechanism 314 that slides when the operating wire 46 is advanced or retreated, and an uneven structure 316 formed on the surface opposite to the uneven structure 316 of the guide part that supports the slider mechanism 314.

[0131] When the slider mechanism 314 slides to move the operating wire 46 back and forth, vibrations generated between the concave-convex structure 316 and the contact member 318 are transmitted to the standing operation lever 12. This allows the operator of the standing operation lever 12 to feel the vibrations in his or her hand, and enables the operator to grasp the operating state of the standing platform 36 and the operating state of the standing operation lever 12.

[0132] <6> The range in which the uneven structure 316 is formed corresponds to the entire range of the operating range of the stand 36. This allows the operator of the standing operation lever 12 to grasp the operating state of the stand 36 and the operating state of the standing operation lever 12 throughout the entire range of the operating range of the stand 36.

[0133] <7> The range in which the uneven structure 316 is formed corresponds to the range in which the erection angle of the erection platform 36 is between 45 degrees and 75 degrees. This allows the operator of the erection operation lever 12 to grasp the operating state of the erection platform 36 and the operating state of the erection operation lever 12 within the range of the erection angle of the erection platform 36, which requires precise adjustment.

[0134] <8> The concave-convex structure 316 has a first pitch applied to a first forming region corresponding to a range in which the rising angle of the riser 36 is equal to or greater than 0 degrees and equal to or less than 45 degrees, and a second pitch finer than the first pitch applied to a second forming region corresponding to a range in which the rising angle of the riser 36 is greater than 45 degrees and equal to or less than 75 degrees. As a result, vibrations with a short period may occur when the rising angle of the riser 36 is greater than 45 degrees and equal to or less than 75 degrees, compared to when the rising angle of the riser 36 is greater than 0 degrees and equal to or less than 45 degrees.

[0135] <9> A first height is applied to the concave-convex structure 316 in a first forming region corresponding to a range in which the rising angle of the riser 36 is equal to or greater than 0 degrees and equal to or less than 45 degrees, and a second height different from the first height is applied to a second forming region corresponding to a range in which the rising angle of the riser 36 is greater than 45 degrees and equal to or less than 75 degrees. As a result, vibrations with different amplitudes may be generated when the rising angle of the riser 36 is in a range in which the rising angle of the riser 36 is greater than or equal to 45 degrees and equal to or less than 45 degrees.

[0136] <10> An asymmetric shape is applied to the concave-convex structure 316 in the direction of the longitudinal axis Ax, which allows the vibration when the stand 36 stands up to be different from the vibration when the stand 36 is laid down.

[0137] The above-described variations of the treatment tool erecting mechanism 300 and the treatment tool erecting mechanism 400 may be appropriately combined. For example, variations in the pitch, height, and shape of the concave-convex structure 316 can also be applied to the treatment tool erecting mechanism 400.

[0138] The present disclosure is not limited to the above-described embodiments, and various modifications are possible within the scope of the gist of the technical idea of ​​the present disclosure. [Explanation of symbols]
