The present application claims priority under 35 U.S.C § 119(a) to Japanese Patent Application No. 2022-093823 filed on Jun. 9, 2022, which is hereby expressly incorporated by reference, in its entirety, into the present application.
The present invention relates to an endoscope device that controls inflation and deflation of a balloon of an endoscope.
In the related art, in a medical field, a procedure of inserting an insertion part of an endoscope into an intestinal tract (lumen) such as a large intestine and a small intestine to observe, diagnose, and treat an inner wall surface of the intestinal tract has been performed. Since the intestinal tract is complicatedly bent, it is difficult to transmit force to a distal end of the insertion part simply by pushing the insertion part of the endoscope, and it is difficult to insert the endoscope into a deep portion.
Therefore, there is known a double-balloon type endoscope device in which balloons capable of inflating and deflating are respectively attached to the insertion part of the endoscope and a distal end portion of an overtube covering the insertion part (see JP2016-137206A, JP2005-296258A, JP2006-149999A, JP2007-111542A, and JP2005-261781A). With this endoscope device, inflation and deflation of each balloon can be individually controlled by supplying and sucking air from a balloon controller to an inside of each balloon. This allows the insertion part to be inserted into an inner side (deep portion) of the complicatedly bent intestinal tract by alternately inserting the insertion part and the overtube while temporarily fixing each balloon individually and at a predetermined time to the intestinal tract.
In the endoscope device disclosed in JP2016-137206A, JP2005-296258A, JP2006-149999A, and JP2007-111542A, switching between inflation and deflation of each balloon can be performed individually by operating a remote controller connected to the balloon controller by an operator (including an assistant, the same applies hereinafter). On the other hand, a switch (controller operation switch) connected to the balloon controller is provided in an operating part of the endoscope of the endoscope device disclosed in JP2005-261781A. By operating this switch by the operator, switching between inflation and deflation of each balloon can be performed individually.
In addition, in the endoscope device disclosed in JP2006-149999A and JP2007-111542A, a balloon state image showing whether each balloon is in an inflated state or a deflated state is displayed on a monitor.
Incidentally, in a case in which the switch provided in the operating part of the endoscope is operated to switch between inflation and deflation of each balloon as in the endoscope device disclosed in JP2005-261781A, there is a problem that it is difficult to instantly grasp which operation is being performed because the operator gazes at the monitor.
In addition, even in a case in which the balloon state image of each balloon is displayed on the monitor as in the endoscope device disclosed in JP2006-149999A and JP2007-111542A, it is premised that a switching operation between inflation and deflation of the balloon is performed using the remote controller, an operation panel, or the like. Therefore, the operator who operates the switch of the operating part cannot directly grasp which operation is being performed.
The present invention has been made in view of such circumstances, and an object of the present invention is to provide an endoscope device that enables an operator to easily grasp which operation is being operated in a case in which the operator operates a controller operation switch provided in an endoscope.

The endoscope 10 comprises a flexible insertion part 17 and an operating part 18 provided consecutively to a base end side of the insertion part 17.
The operating part 18 is used for an operator to perform an operation, and is also referred to as a hand operating part. A universal cable 19 is connected to the operating part 18. The universal cable 19 includes a signal cable (not shown), a light guide (not shown), a first supply/discharge pipe line 31 (see
A cable 21 is branched from the light source connector 20, and the processor connector 22 is provided at a distal end the cable 21. The light source connector 20 is attachably and detachably connected to the light source device 12, and the processor connector 22 is attachably and detachably connected to the processor device 13.
The operating part 18 is provided with a plurality of multifunctional switches 29 in addition to a pair of known angle knobs 23, an air supply/water supply button 27, a suction button 28, and a treatment tool insertion part 18a. Each of the multifunctional switches 29, which will be described in detail below, can selectively assign a plurality of types of operations of the endoscope device 2, such as imaging of an area to be observed, switching of special light observation, and inflation and deflation of the respective balloons 30 and 37, which will be described below (see
The insertion part 17 is inserted into a lumen (for example, a small intestine or a large intestine) of a subject. The insertion part 17 comprises a distal end portion 24, a bendable portion 25, and a soft portion 26 from a distal end side to a base end side.
In addition to an imaging unit 24a (see
The bendable portion 25 is remotely bent (angle operation) by rotating the pair of angle knobs 23 provided in the operating part 18. Accordingly, a distal end surface (observation window and illumination window) of the distal end portion 24 can be directed in a desired direction.
The soft portion 26 is provided consecutively to a base end of the bendable portion 25 and has flexibility. The soft portion 26 has a length of several meters to make the distal end portion 24 reach a target position in the body.
A first balloon 30 corresponding to the balloon of the present invention is attachably and detachably attached to the distal end portion 24. The first balloon 30 is formed in a substantially tubular shape of which an end portion is narrowed by an elastic material such as rubber, and has a balloon distal end portion and a balloon base end portion each having a small diameter, and a central swollen portion. The distal end portion 24 is inserted into the first balloon 30 such that the first balloon 30 is located at a predetermined position of the distal end portion 24, and then, for example, a rubber ring is fitted into the balloon distal end portion and the balloon base end portion. Thus, the first balloon 30 is fixed to the distal end portion 24.
The overtube 11 attachably and detachably covers the insertion part 17. The overtube 11 comprises a grip portion 35 gripped by the operator, a main body portion 36, and a second balloon 37 corresponding to the balloon of the present invention.
The grip portion 35 is a tubular body made of a hard material such as plastic. The main body portion 36 is formed in a substantially tubular shape by a flexible material such as polyurethane, and is externally fitted and fixed to a distal end side of the grip portion 35.
The second balloon 37 is formed in a substantially tubular shape of which an end portion is narrowed by an elastic material such as rubber, and has a balloon distal end portion and a balloon base end portion each having a small diameter, and a central swollen portion. The second balloon 37 covers an outer peripheral surface of a distal end of the main body portion 36, and is fixed to the main body portion 36 by, for example, winding a thread around the balloon distal end portion and the balloon base end portion and applying an adhesive thereon.
As shown in
A distal end side of the first supply/discharge pipe line 31 communicates with an opening 32 for a balloon formed on an outer peripheral surface of the distal end portion 24. The opening 32 is formed at an attaching/detaching position of the first balloon 30 on the outer peripheral surface of the distal end portion 24. In addition, an endoscope-side cap 33 is provided on a base end side of the first supply/discharge pipe line 31.
The endoscope-side cap 33 is formed integrally with the light source connector 20. The endoscope-side cap 33 is connected to the balloon controller 14 via a tube 34. Accordingly, by the balloon controller 14 described below, air can be supplied to the inside of the first balloon 30 to inflate the first balloon 30 or, conversely, air can be sucked from the inside of the first balloon 30 to deflate the first balloon 30, via the tube 34, the endoscope-side cap 33, the first supply/discharge pipe line 31, and the opening 32. Note that the term “air” as used herein is gas for inflating the first balloon 30 (also including the second balloon 37 described below), and a type (component) thereof is not particularly limited. In addition, various fluids including a liquid such as water may be used instead of “air”.
A supply pipe line 38 and a second supply/discharge pipe line 39 are formed inside the main body portion 36 of the overtube 11 in an axial direction thereof. The supply pipe line 38 is a hole through which the insertion part 17 of the endoscope 10 is inserted, and an inner diameter thereof is formed to be slightly larger than an outer diameter of the insertion part 17.
In a case in which the overtube 11 is used, a lubricant such as water is supplied to an inner peripheral surface (gap between the insertion part 17 and the main body portion 36) of the supply pipe line 38 to reduce friction between the insertion part 17 and the main body portion 36. The lubricant is injected from a connector 40 (see
The second supply/discharge pipe line 39 is a pipe line for supplying and sucking air to the second balloon 37, and is provided in a pipe wall of the supply pipe line 38. A distal end side of the second supply/discharge pipe line 39 communicates with an opening 41 for a balloon formed on an outer peripheral surface of the main body portion 36. The opening 41 is formed at an attaching/detaching position of the second balloon 37 on the outer peripheral surface of the main body portion 36. In addition, a tube 42 having a small diameter is provided consecutively to a base end side of the second supply/discharge pipe line 39, and a connector 43 is provided consecutively to a base end side of the tube 42.
A tube 44 is connected to the connector 43, and the tube 44 is further connected to the balloon controller 14. Accordingly, by the balloon controller 14 described below, air can be supplied to the inside of the second balloon 37 to inflate the second balloon 37 or, conversely, air can be sucked from the inside of the second balloon 37 to deflate the second balloon 37, via the tube 44, the connector 43, the tube 42, the second supply/discharge pipe line 39, and the opening 41.
Returning to
Further, some of a plurality of multifunctional switches 29 provided in the operating part 18 are electrically connected to the balloon controller 14 via a signal cable (not shown).
The balloon controller 14 individually controls the inflation and deflation of the respective balloons 30 and 37 in accordance with an operation input with respect to the remote controller 15 or the multifunctional switch 29 by the operator. For example, the balloon controller 14 individually supplies air to the respective balloons 30 and 37 to individually inflate the respective balloons 30 and 37, or controls the air pressure to a certain value to individually maintain the respective balloons 30 and 37 in an inflated state. In addition, the balloon controller 14 individually sucks air from the respective balloons 30 and 37 to individually deflate the respective balloons 30 and 37, or controls the air pressure to a certain value to individually maintain the respective balloons 30 and 37 in a deflated state.
A display part 46, a power switch 47, an emergency stop switch 48, a tube connecting portion 49, and the like are provided on a front surface of the balloon controller 14.
In a case in which the respective balloons 30 and 37 are inflated or deflated, the display part 46 displays a pressure value of the balloons 30 and 37 and information indicating an inflation and deflation state (whether the inflated state or the deflated state) of the respective balloons 30 and 37. In addition, an error code is displayed on the display part 46 in a case in which an abnormality, such as tear in the respective balloons 30 or 37, occurs. In a case in which the error code is displayed on the display part 46, the balloon controller 14 outputs a buzzer sound from a speaker (not shown).
The power switch 47 is used to turn on and off the power of the balloon controller 14. The emergency stop switch 48 is used for an emergency stop of the balloon controller 14 (an emergency stop of the inflation and deflation operation of the respective balloons 30 and 37). The emergency stop referred to here includes, for example, stopping the inflation and deflation operation of the respective balloons 30 and 37, or deflating the respective balloons 30 and 37. Note that the emergency stop may be executed individually for the respective balloons 30 and 37.
The aforementioned tubes 34 and 44 are each connected to the tube connecting portion 49. Although not shown, the tube connecting portion 49 is provided with a backflow prevention unit. The backflow prevention unit prevents a body fluid or the like from flowing into the balloon controller 14 in a case in which the respective balloons 30 and 37 are torn.
The remote controller 15 has a shape appropriate for being gripped by the operator, and is provided with, on a front surface, a first balloon operating part 51, a second balloon operating part 52, a first balloon state display part 53, a second balloon state display part 54, a first balloon pause button 55, a second balloon pause button 56, a stop button 57, and the like. The first balloon operating part 51, the second balloon operating part 52, the first balloon pause button 55, the second balloon pause button 56, and the stop button 57 are used for the plurality of types of balloon operations described above, and correspond to a plurality of types of individual operation switches of the present invention.
The first balloon operating part 51 is positioned on a right side of the remote controller 15 in a case in which the remote controller 15 is viewed from the front, and is a circular toggle switch for performing the inflation operation and the deflation operation of the first balloon 30 with respect to the balloon controller 14. In the present embodiment, the first balloon operating part 51 is also formed to be black (indicated by hatching in the figure) in accordance with the general color (black) of the endoscope 10.
Each time the first balloon operating part 51 is pushed, the inflation operation of the first balloon 30 and the deflation operation of the first balloon 30 are alternately input to the balloon controller 14. Accordingly, in a case in which the inflation operation of the first balloon 30 is input, the balloon controller 14 supplies air to the first balloon 30 to inflate the first balloon 30, and, conversely, in a case in which the deflation operation of the first balloon 30 is input, the balloon controller 14 sucks air from the first balloon 30 to deflate the first balloon 30.
The first balloon state display part 53 is provided in the first balloon operating part 51, and has an inflated state display part 53A and a deflated state display part 53B. The inflated state display part 53A displays an inflated state in which the first balloon 30 is inflated by supplying air from the balloon controller 14 to the first balloon 30. The deflated state display part 53B displays a deflated state in which the first balloon 30 is deflated by sucking air from the first balloon 30.
The inflated state display part 53A is disposed along an outer periphery of the first balloon operating part 51, and is a ring-shaped state display part that indicates an inflated state of the first balloon 30. The deflated state display part 53B is disposed inside the inflated state display part 53A (on the first balloon operating part 51), and is a flat-shape state display part that indicates a deflated state of the first balloon 30. Since the detailed configuration of the inflated state display part 53A and the deflated state display part 53B is a known technology (see JP2016-137206A above), specific description thereof will be omitted here.
The inflated state display part 53A switches to a display state (light emitting state) in a case in which the first balloon 30 is in an inflated state, and switches to a non-display state (non-light emitting state) in a case in which the first balloon 30 is in a deflated state. On the other hand, the deflated state display part 53B switches to a display state (light emitting state) in a case in which the first balloon 30 is in a deflated state, and switches to a non-display state (non-light emitting state) in a case in which the first balloon 30 is in an inflated state. Therefore, any one of the inflated state display part 53A or the deflated state display part 53B is in a display state, and the other is in a non-display state.
The second balloon operating part 52 is provided on a left side of the remote controller 15 in a case in which the remote controller 15 is viewed from the front, and located at a position symmetrical to the first balloon operating part 51 with respect to a center line of the remote controller 15. The second balloon operating part 52 is a circular toggle switch for performing the inflation operation and the deflation operation of the second balloon 37 with respect to the balloon controller 14. In the present embodiment, the second balloon operating part 52 is also formed to be white in accordance with the general color (white) of the overtube 11.
Each time the second balloon operating part 52 is pushed, the inflation operation of the second balloon 37 and the deflation operation of the second balloon 37 are alternately input to the balloon controller 14. Accordingly, in a case in which the inflation operation of the second balloon 37 is input, the balloon controller 14 supplies air to the second balloon 37 to inflate the second balloon 37, and, conversely, in a case in which the deflation operation of the second balloon 37 is input, the balloon controller 14 sucks air from the second balloon 37 to deflate the second balloon 37.
The second balloon state display part 54 has an inflated state display part 54A and a deflated state display part 54B. The inflated state display part 54A is provided along an outer periphery of the second balloon operating part 52, and is a ring-shaped state display part that indicates an inflated state in which the second balloon 37 is inflated. The deflated state display part 54B is provided inside the inflated state display part 54A (on the second balloon operating part 52), and is a flat-shape state display part that indicates a deflated state in which the second balloon 37 is deflated.
The inflated state display part 54A switches to a display state (light emitting state) in a case in which the second balloon 37 is in an inflated state, and switches to a non-display state (non-light emitting state) in a case in which the second balloon 37 is in a deflated state. On the other hand, the deflated state display part 54B switches to a display state (light emitting state) in a case in which the second balloon 37 is in a deflated state, and switches to a non-display state (non-light emitting state) in a case in which the second balloon 37 is in an inflated state. Therefore, any one of the inflated state display part 54A or the deflated state display part 54B is in a display state, and the other is in a non-display state.
In this way, by referring to the display of the inflated state display part 53A and the deflated state display part 53B and the display of the inflated state display part 54A and the deflated state display part 54B, the operator can discriminate whether the respective balloons 30 and 37 are in an inflated state or in a deflated state.
In addition, as shown in
Further, as shown in
Returning to
The first balloon pause button 55 is provided below the character string of “ENDOSCOPE”, and the second balloon pause button 56 is provided below the character string of “OVERTUBE”. The first balloon pause button 55 and the second balloon pause button 56 are rectangular push buttons. A character string of “PAUSE” meaning a pause is attached between the first balloon pause button 55 and the second balloon pause button 56.
The first balloon pause button 55 inputs a pause operation of an inflated state and a deflated state of the first balloon 30 to the balloon controller 14. The balloon controller 14 that has received the input of the pause operation maintains the first balloon 30 in an inflated state by maintaining the pressure of the air supplied to the first balloon 30 at a constant value, or maintains the first balloon 30 in a deflated state by maintaining the pressure of the air sucked from the first balloon 30 at a constant value.
The second balloon pause button 56 inputs a pause operation of an inflated state and a deflated state of the second balloon 37 to the balloon controller 14. The balloon controller 14 that has received the input of the pause operation maintains the second balloon 37 in an inflated state by maintaining the pressure of the air supplied to the second balloon 37 at a constant value, or maintains the second balloon 37 in a deflated state by maintaining the pressure of the air sucked from the second balloon 37 at a constant value.
The stop button 57 is provided below the first balloon pause button 55 and the second balloon pause button 56 and on the center line of the remote controller 15. The stop button 57 is a rectangular push button. A character string of “STOP” meaning a stop is attached above the stop button 57.
The stop button 57 outputs a stop operation of the aforementioned buzzer sound (including an error code display) to the balloon controller 14. The balloon controller 14 stops the output of the buzzer sound in a case in which the stop operation is input while the buzzer sound is being output. In addition, instead of using the stop button 57 for the stop operation of the buzzer sound, the stop button 57 may be used for the aforementioned emergency stop of the inflation and deflation operation of the respective balloons 30 and 37.
As shown in
Therefore, each time the multifunctional switch 29e is pushed, the inflation operation of the first balloon 30 and the deflation operation of the first balloon 30 are alternately input to the balloon controller 14 via a signal cable (not shown). In addition, each time the multifunctional switch 29d is pushed, the inflation operation of the second balloon 37 and the deflation operation of the second balloon 37 are alternately input to the balloon controller 14 via a signal cable (not shown). Accordingly, by pushing the multifunctional switches 29e and 29d, the respective balloons 30 and 37 can be individually switched between the inflation state and the deflation state. Operation information of the multifunctional switch 29e (inflation operation and deflation operation of the first balloon 30) and operation information of the multifunctional switch 29d (inflation operation and deflation operation of the second balloon 37) are alto sequentially input to the processor device 13 via a signal cable (not shown).
A function of the stop button 57 may be assigned to the multifunctional switch 29c. In addition, a function as an imaging button for executing the capturing of an image of the area to be observed by the imaging unit 24a (see
Returning to
The processor device 13 comprises an arithmetic circuit configured of various processors, a memory, and the like. Various processors include a central processing unit (CPU), a graphics processing unit (GPU), an application specific integrated circuit (ASIC), and a programmable logic device [for example, simple programmable logic devices (SPLD), complex programmable logic device (CPLD), and field programmable gate arrays (FPGA)]. Note that various functions of the processor device 13 may be realized by one processor or may be realized by a plurality of processors of the same type or different types.
The processor device 13 has a normal mode and a balloon operation presentation mode as a display mode for displaying the endoscopy screen 100 on the monitor 16. The normal mode is a display mode selected in a case in which the remote controller 15 is used for the input of the balloon operations (inflation operation, deflation operation, and the like) of the respective balloons 30 and 37. Since the normal mode is the same as the mode in the related art, the description thereof will be omitted here.
The balloon operation presentation mode is a display mode selected in a case in which the multifunctional switch 29 (here, in particular, the multifunctional switches 29e and 29d) is used for the input of the balloon operations of the respective balloons 30 and 37. As described above, in a case in which the inflation operation and the deflation operation of the first balloon 30 are performed by using the multifunctional switch 29e, or the inflation operation and the deflation operation of the second balloon 37 are performed by using the multifunctional switch 29d, it is difficult to instantly grasp which balloon operation is being performed because the operator gazes at the monitor 16. Therefore, in a case in which the balloon operation presentation mode is selected, the processor device 13 causes the monitor 16 to display, together with the endoscope image 70, a remote controller image 72 in which the operator can easily identify the type of the balloon operation input to the multifunctional switch 29.
The display control unit 80 sequentially generates the endoscopy screen 100 and sequentially outputs it to the monitor 16 based on the imaging signal sequentially input from the imaging unit 24a via a signal cable (not shown) and the operation information of the multifunctional switches 29e and 29d sequentially input from the operating part 18 via a signal cable (not shown).
The endoscopy screen 100 is broadly divided into a first display region 100a and a second display region 100b. The first display region 100a displays the endoscope image 70 of a known area to be observed, which is generated by the display control unit 80 based on the imaging signal. The second display region 100b displays the remote controller image 72 generated by the display control unit 80 based on the operation information of the multifunctional switches 29e and 29d.
In the present embodiment, the endoscope image 70 and the remote controller image 72 are displayed in the first display region 100a and the second display region 100b, which are different from each other, in the endoscopy screen 100, but for example, the remote controller image 72 may be superimposed (superposed) on the endoscope image 70. Alternatively, the remote controller image 72 may be displayed in a display window different from a display window of the endoscope image 70 by a picture-in-picture method.
The remote controller image 72 includes at least a first balloon operating part image 51P corresponding to the first balloon operating part 51 and a second balloon operating part image 52P corresponding to the second balloon operating part 52. Here, in the present embodiment, the first balloon operating part 51 is provided with the first balloon state display part 53, and the second balloon operating part 52 is provided with the second balloon state display part 54. Therefore, the remote controller image 72 includes a first balloon state display part image 53P corresponding to the first balloon state display part 53, and a second balloon state display part image 54P corresponding to the second balloon state display part 54.
The first balloon state display part image 53P includes an inflated state display part image 53AP corresponding to the inflated state display part 53A and a deflated state display part image 53BP corresponding to the deflated state display part 53B. In addition, the second balloon state display part image 54P includes an inflated state display part image 54AP corresponding to the inflated state display part 54A and a deflated state display part image 54BP corresponding to the deflated state display part 54B.
In the remote controller image 72, similarly to the remote controller 15, a character string or an illustration indicating the endoscope 10 (that is, the first balloon 30) is displayed at a position near the first balloon operating part image 51P, and a character string or an illustration indicating the overtube 11 is displayed at a position near the second balloon operating part image 52P.
Each time the inflation operation or the deflation operation is input to the multifunctional switches 29e and 29d, the display control unit 80 reflects the type of the input operation on the remote controller image 72. For example, the display control unit 80 changes a display mode of the inflated state display part image 53AP in a case in which the inflation operation is performed with respect to the multifunctional switch 29e, and changes a display mode of the deflated state display part image 53BP in a case in which the deflation operation is performed with respect to the multifunctional switch 29e, based on the operation information input from the operating part 18.
In addition, for example, the display control unit 80 changes a display mode of the inflated state display part image 54AP in a case in which the inflation operation is performed with respect to the multifunctional switch 29d, and changes a display mode of the deflated state display part image 54BP in a case in which the deflation operation is performed with respect to the multifunctional switch 29d, based on the operation information input from the operating part 18.
The change in the display modes of the inflated state display part images 53AP and 54AP and the deflated state display part images 53BP and 54BP referred to here means, for example, blinking individual images or changing a color, shape, or size of the individual images.
As shown in
In addition, as shown in
Further, as shown in
Hereinafter, each time the operator inputs the inflation operation or the deflation operation of the respective balloons 30 and 37 with respect to the multifunctional switches 29e and 29d, the change in the display modes of the first balloon operating part image 51P (the inflated state display part image 53AP or the deflated state display part image 53BP) and the second balloon operating part image 52P (the inflated state display part image 54AP or the deflated state display part image 54BP) by the display control unit 80 is repeatedly executed.
As described above, in the first embodiment, the change in the display mode of the first balloon operating part image 51P corresponding to the inflation operation and the deflation operation of the first balloon 30 with respect to the multifunctional switch 29e and the change in the display mode of the second balloon operating part image 52P corresponding to the inflation operation and the deflation operation of the second balloon 37 with respect to the multifunctional switch 29d are executed. As a result, the inflation operation and the deflation operation of the first balloon 30 with respect to the multifunctional switch 29e are individually reflected on the remote controller image 72, and the inflation operation and the deflation operation of the second balloon 37 with respect to the multifunctional switch 29d are individually reflected on the remote controller image 72. Accordingly, the operator can easily grasp what kind of operation has been performed on the multifunctional switches 29e and 29d in a state in which the operator gazes at the monitor 16.
In addition, in the present embodiment, the operation with respect to the multifunctional switches 29e and 29d is reflected on the remote controller image 72 of the remote controller 15 used for the inflation operation and the deflation operation of the respective balloons 30 and 37. Accordingly, the operator can more intuitively grasp which switch of the remote controller 15 the operation with respect to the multifunctional switches 29e and 29d corresponds to, as compared with the case in which only the character string or the illustration indicating the inflation operation and the deflation operation of the respective balloons 30 and 37 is displayed on the monitor 16.
As shown in
The pressure sensor 81 corresponds to a pressure detection sensor of the present invention, and is provided corresponding to the respective balloons 30 and 37 in the balloon controller 14. The pressure sensor 81 repeatedly executes detection of the pressure in the first balloon 30 and detection of the pressure in the second balloon 37 while the balloon controller 14 is being operated. Since a method of detecting the pressure in the respective balloons 30 and 37 by the pressure sensor 81 is a known technology (for example, see JP2005-261781A above), specific description thereof will be omitted here. The pressure sensor 81 may be provided in the endoscope 10 instead of being provided in the balloon controller 14. Then, each time the pressure sensor 81 detects the pressure in the respective balloons 30 and 37, a pressure detection result of the respective balloons 30 and 37 is repeatedly output to the processor device 13 via a communication cable (not shown).
The pressure information acquisition unit 82 repeatedly executes acquisition of the pressure detection results of the respective balloons 30 and 37 from the pressure sensor 81 and output of the pressure detection results of the respective balloons 30 and 37 to the display control unit 80.
The display control unit 80 according to the second embodiment sequentially generates the endoscopy screen 100 and sequentially outputs it to the monitor 16 based on the imaging signal sequentially input from the imaging unit 24a, the operation information of the multifunctional switches 29e and 29d sequentially input from the operating part 18, and the output of the pressure detection results of the respective balloons 30 and 37 input from the pressure information acquisition unit 82.
The endoscopy screen 100 according to the second embodiment is basically the same as the endoscopy screen 100 according to the first embodiment except that the second display region 100b includes, in addition to the remote controller image 72, first pressure information 74 indicating the pressure in the first balloon 30 and the second pressure information 75 indicating the pressure in the second balloon 37.
The first pressure information 74 includes an indicator 74A indicating magnitude of the pressure in the first balloon 30, and a pressure numerical value 74B indicating a numerical value of the pressure in the first balloon 30. The second pressure information 75 includes an indicator 75A indicating magnitude of the pressure in the second balloon 37, and a pressure numerical value 75B indicating a numerical value of the pressure in the second balloon 37.
In the second embodiment, both the indicator 74A and the pressure numerical value 74B are displayed in the remote controller image 72 as the first pressure information 74, but only any one of the indicator 74A or the pressure numerical value 74B may be displayed. For example, by operating a display changeover switch (a function may be assigned to the multifunctional switch 29) (not shown) provided in the balloon controller 14, it is possible to switch between displaying both the indicator 74A and the pressure numerical value 74B, displaying only the indicator 74A, and displaying only the pressure numerical value 74B. Similarly, for the second pressure information 75, it may be possible to switch between displaying both the indicator 75A and the pressure numerical value 75B, displaying only the indicator 75A, and displaying only the pressure numerical value 75B.
Hereinafter, the display control unit 80 updates the display of the first pressure information 74 and the second pressure information 75 each time new pressure detection results of the respective balloons 30 and 37 are input from the pressure information acquisition unit 82.
As described above, in the second embodiment, by displaying the first pressure information 74 and the second pressure information 75 on the monitor 16, the operator can easily grasp the pressure in the respective balloons 30 and 37 in a state in which the operator gazes at the monitor 16. In addition, by displaying the first pressure information 74 at a position near the first balloon operating part image 51P and displaying the second pressure information 75 at a position near the second balloon operating part image 52P, the operator can easily distinguish between the pressure in the first balloon 30 and the pressure in the second balloon 37.
In the second embodiment, the first pressure information 74 and the second pressure information 75 are displayed at positions near the remote controller image 72, but the first pressure information 74 may be superimposed on the first balloon operating part image 51P, and the second pressure information 75 may be superimposed on the second balloon operating part image 52P. In addition, the first pressure information 74 and the second pressure information 75 may be displayed at any positions in the endoscopy screen 100.
Therefore, in the endoscope device 2 according to the third embodiment, a foot switch 110 for emergency stop is connected to the balloon controller 14. The endoscope device 2 according to the third embodiment has basically the same configuration as the endoscope device 2 according to each of the above-described embodiments except that the foot switch 110 is provided and the functions of the display control unit 80 are partially different. Therefore, the same reference numerals are given to those having the same function or configuration as those of each of the above-described embodiments, and the description thereof will be omitted.
The foot switch 110 corresponds to the emergency stop switch of the present invention, and receives a foot operation (foot-step operation) by an operator's foot. The balloon controller 14 according to the third embodiment executes an emergency stop (a stop of the inflation and deflation operation of the respective balloons 30 and 37 or deflation of the respective balloons 30 and 37) in a case in which the foot operation is performed with respect to the foot switch 110. Two foot switches 110 may be connected to the balloon controller 14 so that the balloon controller 14 can individually execute the emergency stop of the respective balloons 30 and 37.
As described above, in the third embodiment, since an emergency stop of the balloon controller 14 can be performed by the foot switch 110, the emergency stop of the balloon controller 14 can be quickly executed even in a case in which both hands of the operator are full.
In the third embodiment, the emergency stop of the balloon controller 14 is made possible by the foot switch 110, but for example, the function of the emergency stop switch may be provided in the remote controller 15 or the multifunctional switch 29.

As long as the operator can grasp the type of the balloon operation input to the multifunctional switch 29, the method of reflecting the type of the balloon operation on the remote controller image 72 is not particularly limited. For example, a character string or an illustration indicating the type of the balloon operation input to the multifunctional switch 29 may be displayed on the remote controller image 72 or at a position near the remote controller image 72.
In each of the above-described embodiments, the functions of the respective balloon operating parts 51 and 52 of the remote controller 15 are assigned to each multifunctional switch 29, but the functions of the stop button 57 as shown in

Further, the multifunctional switch 29 or the dedicated operation switch may be provided in addition to the operating part 18 of the endoscope 10.
In each of the above-described embodiments, the remote controller image 72, the first pressure information 74, and the second pressure information 75 are displayed on the endoscopy screen 100 only in the balloon operation presentation mode in which the multifunctional switch 29 is used, but the remote controller image 72, the first pressure information 74, and the second pressure information 75 may be displayed on the endoscopy screen 100 even in the normal mode. In this case, the operation on the remote controller 15 is reflected on the remote controller image 72.
Although the double-balloon type endoscope device 2 has been described in each of the above-described embodiments, the present invention can also be applied to a single-balloon type endoscope device 2 (endoscope 10).
