Description

[Technical field]

[0001] The present disclosure relates to a relay adapter, an endoscope system and a signal processing method in a relay adapter. [State of the art]

[0002] Traditionally, relay cables are proposed to enable the connection of reusable endoscopes (i.e., conventional endoscopes that are cleaned and reused) and disposable endoscopes (i.e., single-use endoscopes) to a common processor. For example, patent document 1 aims to “provide an endoscope image acquisition device that can be used with two types of endoscopes with different connector shapes, can be easily operated by a switch in an endoscope control unit, and can simplify the connection between a connector socket and a signal processing circuit,” disclosing that “an endoscope 2 for reuse and an endoscope 3 for single use have electrical connectors.” 22 or 23 with different shapes and the electrical plug 22the endoscope 2 can be detachably connected for reuse to an electrical connector 26 provided in a video processor 6, while the electrical connector 23 of the other endoscope 3 is connected for single use to an electrical socket 32 ​​provided at one end of a relay cable 8, and an electrical plug 33 provided at the other end of this relay cable 8 can be detachably connected to the electrical socket 26 of the video processor 6” (see the summary of patent document 1).

[0003] [Patent Document 1] JP Patent Disclosure No. 7-313454 [Overview of the invention][Problem to be solved by the invention]

[0004] Patent document 1, however, only discloses a relay cable designed for different connector types between a reusable endoscope and a disposable endoscope. Therefore, if the signal format is the same for both endoscopes, or if the signal formats differ, it is necessary to convert the signal format into one that can be processed by the processor in the disposable endoscope (which typically uses the same format as a signal output by the reusable endoscope). While it is desirable to keep costs as low as possible, given the single-use nature of the disposable endoscope, the cost of disposable endoscopes increases if the signal format conversion process is required, as the circuitry becomes more complex and the number of components increases.

[0005] The present disclosure was made in light of this situation and provides a technique that makes it possible to connect and use a disposable endoscope (a single-use endoscope) with an existing endoscope system (an existing processor) without incurring the high costs of the disposable endoscope. [Means of solving the problem]

[0006] To solve the above problem, the present embodiment discloses a relay adapter for connecting a processor and an endoscope device, provided with a first connector part for connecting the endoscope device, a second connector part for connecting the processor, a memory part for storing a program for controlling the operation of the relay adapter, and a control part that reads the program from the memory part and executes it, wherein the control part performs: processing to obtain first specification information including the content of the signal processing in the endoscope device and second specification information including the content of the signal processing in the processor, processing to compare the first specification information with the second specification information, and to convert a signal received from the endoscope device based on the comparison result.so that the processor can process the signal received from the endoscope device, and to generate a conversion signal, as well as to process and output the conversion signal to the processor.

[Embodiments of the invention]

[0010] The present embodiment relates to a relay adapter that enables the connection and use of a disposable (i.e., single-use) endoscope with a processor for a reusable endoscope, as well as an endoscope system equipped therewith. The endoscope system is described in more detail below, with a focus on the design and operation of the relay adapter. <Ausbildung des Endoskopsystems>

[0011] Fig. Figure 1 shows a schematic training example of an endoscope system 1 according to the present embodiment. The in Fig. 1 Endoscope system shown 1 is equipped with a disposable endoscope device 10 , a processor 20 for a reusable endoscope, a monitor 30 , a relay adapter 40 and a server 50 , which is connected to a network via the relay adapter 40 is connected. The relay adapter40 is connected to a plug part 106 of the disposable endoscope device 10 and connected to a connector part 201 of the processor for the reuse endoscope.

[0012] The relay adapter 40 is a device for connecting the disposable endoscope device 10 with the processor 20 for the reusable endoscope, and has, for example, a function that, regardless of whether there is a mismatch in the physical shape of the two connectors (even if there is a physical mismatch, a structural connection can still be guaranteed), a mismatch between a signal format (video and control signal format) that is intended for the disposable endoscope device 10 is used, and eliminates a signal format that is used by the processor. 20 can be processed for the reusable endoscope.

[0013] The endoscope system 1According to the present embodiment, the server is also 50 equipped with a network 60 with the relay adapter 40 is connected, the server 50 However, this is not necessary and it is also possible to use the relay adapter. 40 a data management function of the server 50 (e.g., a function for managing information about the usage situation of each disposable endoscope device) 10 ) to lend. If a server 50 Once installed, the server 50 e.g. trained in such a way that on the server 50 can be accessed from a computer that is not shown, and which is on the server 50 The stored data can be searched. This is possible when using the disposable endoscope device. 10 a serial number (identification information) of the endoscope device to the server 50to be sent in order to determine in advance whether the endoscope device has been used or not.

[0014] The disposable endoscope device 10 comprises: a pointed part 101 with an imaging part that is inserted into the interior of an object under investigation (not shown), a curved part 102 that can be actuated in a curved position inside the object under investigation, a slim tubular soft part 103, an operating part 104 that is connected to the soft part 103 and operated by a user (operator), a plug cable part 105 that extends from the operating part 104 and connects to the relay adapter 40 is connected, and a plug part 106, which connects to the relay adapter 40 represents the connected part. The endoscope 10According to the present embodiment, it can also be designed such that a section from the curved part 102 to the connector part 106 is used only once, and only the tip part 101 or the imaging part included in this tip part 101 (e.g., in the tip part 101, an element (e.g., a resin element) that accommodates an image sensor is removed and the image sensor is exposed) is used by the endoscope 10 is separated, cleaned and reused (see Fig. 2) The pointed part 101, the curved part 102, and the soft part 103 can be collectively referred to as the insertion part. Here, the boundary between the reusable part and the disposable part is considered to be the boundary between the pointed part 101 and the curved part 102; however, the boundary could also be a predetermined position along the path of the curved part 102 or a predetermined position along the path of the soft part 103.

[0015] The part of the disposable endoscope device 10 , which is inserted into the body of the object under investigation, consists of the tip part 101, the curved part 102, which is connected coaxially to the soft part 103 and is relatively short and can be freely curved, and the soft part (a flexible insertion tube) 103, which is connected to the operating part 104 and is relatively long.

[0016] Inside the soft part 103 and the curved part 102, an imaging signal cable, a power supply cable, etc., extend along the axial direction of the soft part 103 and the curved part 102. Although not shown, the soft part 103 and the curved part 102 incorporate a treatment device insertion channel, two air / water supply hoses, a secondary water supply hose, and a spiral or tubular guide hose (which may be designed to contain a tightly wound coil of guide metal) through which an angled wire is passed. An optical fiber bundle for illumination may also be incorporated.

[0017] As in Fig. As shown in Figure 1, the control unit 104 has a control unit body 104a, which forms a control and handle part, and a treatment device insertion opening 104c, which is provided near the soft part 103 of the control unit body 104a. The treatment device insertion opening 104c is an opening of the aforementioned treatment device insertion channel on the side of the control unit 104. The control unit body 104a has a curvature actuation button 104b for actuating a curvature of the curved part 102 and a switch, etc., relating to the respective operation of the endoscope. 10 planned.

[0018] The processor 20 For the reusable endoscope, a device for processing image data is required, which is captured by the imaging part (image sensor). 13 ), which is located in the tip section 101 of the disposable endoscope device 10 is included, recorded, through the relay adapter 40The signal is subjected to a predefined processing procedure and transmitted via the imaging signal cable to generate a video signal. The processor 20 The reusable endoscope transmits the generated video signal to the monitor. 30 This displays an internal image of the recorded object on the monitor. 30 displayed. <Gesamtaufbau des Einweg-Endoskopgeräts 10 >

[0019] Although the disposable endoscope device 10 also in Fig. As explained in point 1, it will be explained in more detail here. Fig. Figure 2 illustrates the overall external structure of the disposable endoscope device. 10 In Fig. 2. The position and shape of the control element 104 may differ from the actual position and shape due to the representation in the drawing.

[0020] The disposable endoscope device 10The device is provided, for example, with the tip part 101, the curved part 102, the soft part 103, the control part 104, the connector cable part 105, and the connector part 106. Apart from the tip part 101, the curved part 102, the soft part 103, the control part 104, the connector cable part 105, and the connector part 106 may be made of a more flexible (softer) resin than the tip part 101. The resin used for the curved part 102, the soft part 103, and the connector cable part 105 is preferably a multi-lumen structure. Examples of such highly flexible resins include: PTFE (polytetrafluoroethylene), ePTFE (expanded PTFE), PE (polyethylene), HDPE (high-density polyethylene), PP (polypropylene) (these are porous materials), PU (polyurethane), PP (polypropylene), PE (polyethylene), and polyamide (polyamide) (these are non-porous materials). In disposable endoscopes 10Parts and elements, apart from those offered for reuse, such as an image sensor contained in tip part 101, and metal parts and elements used in conventional endoscopes, can be largely replaced by resin elements.

[0021] The tip section 101 comprises, for example: an image sensor such as CMOS or CCD, a small LED for illumination, a memory (this can be memory integrated into the image sensor or an RFID tag or EEPROM mounted separately from the image sensor), a lens attached to the image sensor, a light-diffusing lens attached to the LED, a clamp opening, an air supply opening (replacing an air supply nozzle in a conventional endoscope), a water supply opening (replacing a water supply nozzle in a conventional endoscope), and a water jet opening. The tip section 101 is designed to be bonded with a resin that is harder and less deformable than other parts of the disposable endoscope device. 10The image sensor, the small LED, the memory, etc., are covered. In this case, the parts corresponding to the nozzle (air and water supply nozzles) and the lens for illumination are preferably molded in one piece with the tip part 101 using resin. An ultra-wide-angle lens can be used as the objective lens, and a flat, thin resin film can be applied to the objective lens to prevent contamination. The tip part 101 and the curved part 102 are joined by an adhesive such as tape or a bonding agent and are designed in such a way that a user (e.g., a hospital physician) cannot detach the tip part 101 from the endoscope. 10 It can separate. It can also be designed in such a way that, if the tip part 101 of the endoscope 10 When a part is separated (e.g., the internal structure or the structure of the attachment part on the endoscope), the separation involves a part (e.g., the internal structure or the structure of the attachment part on the endoscope). 10) of the tip part 101 will deform or damage it and prevent the user from reusing the tip part 101. The image sensors and small LEDs incorporated in the tip part 101 have the same characteristics as those incorporated in the tip part of an ordinary reusable endoscope. Since the image sensors and small LEDs are expensive, the tip part 101 or the image sensors incorporated therein, etc., are protected by the manufacturer or specialists of the endoscope. 10 cleaned and offered for reuse after the disposable endoscope device 10is picked up from the hospital. Apart from the tip section 101, the curved section 102, the soft section 103, the control unit 104, and the connector cable section 105 are disposed of (e.g., incinerated). In other words, a new disposable endoscope is made from the cleaned and sterilized tip section 101, along with a completely new curved section 102, soft section 103, control unit 104, and connector cable section 105. 10 manufactured and returned to the hospital.

[0022] The curved part 102 consists entirely of resin, as described above. For example, the curved part 102 preferably consists of resin with a multi-lumen structure. In the curved part 102, as described above... Fig. As shown in Figure 2, a resin tube forming a clamping tube, a resin tube forming an air supply tube, a resin tube forming a water supply tube, and a resin tube forming a secondary water supply tube protrude from the end face of the curved part 102. If the illumination light is introduced not by an LED but by an optical fiber, a fiber optic bundle for illumination also protrudes from this end face. Each of the four resin tubes is inserted into each of the insertion ports (clamping, air supply, water supply, and water jet ports) of the tip part 101, which are connected to the curved part 102, and the tip part 101 and the curved part 102 are firmly connected to each other.

[0023] The soft part 103 can be formed, for example, from a plastic spiral tube or from a resin with a multi-lumen structure. No metal sheet or wire is inserted into the soft part 103; instead, a resin tube, etc., with a higher hardness than the resin used for the outer part (outer skin part) of the soft part 103 is inserted. This allows only the curved part 102 to be curved. In addition to the aforementioned resin wire (resin angle wire) or metal wire and the high-hardness resin tubes, the components of the soft part 103 and the curved part 102 include electrical cables for power supply, signal transmission, and a switch. In the case of wireless signal transmission, the components are, for example,a resin or metal angle wire, a resin coil, a power supply line (electrical cable), a line for transmitting an electrical signal from a signal antenna installed in the soft part, and a cable for a switch.

[0024] The control unit 104 is also preferably made entirely of resin. The control unit 104 is provided, for example, with the control unit body 104a, which forms the operating and handle part, an electrical switch 104b, and a treatment device insertion opening 104c, which is located on the side near the soft part 103 of the control unit body 104a. The user (e.g., an operator such as a physician) can, for example, control the suction, air, and water supply using the electrical switch 104b provided in the control unit 104. Since the various functions can be switched using the electrical switch 104b in this way, backflow of mucus, blood, etc., can be completely prevented. The internal structure of the control unit 104 can also be molded in one piece using slide injection molding, etc.

[0025] The connector cable part 105 and the connector part 106 are also made entirely of resin. The connector cable part 105 accommodates a portion of the cable that extends from the control part 104 to the tip part 101. The connector part 106 may also contain an electrical or electronic circuit. Furthermore, the connector part 106 may be equipped, for example, with a suction nipple (made of resin), an air supply nipple (made of resin), a water supply nipple (made of resin), and a water jet opening. <Frontaufbau des Spitzenteils des Einweg-Endoskopgeräts>

[0026] Fig. Figure 3 shows the front assembly with the tip part 101 of the disposable endoscope device. 10The tip section 101 contains, for example: an objective lens 31 of the imaging section (including an image sensor such as a CMOS or CCD), a clamp opening 32 which serves as a treatment device insertion channel, an air / water opening 33 to which two air / water supply hoses are attached, a water jet opening 34 to which a secondary water supply hose is attached, and a light distribution lens 35 to which an illumination light (LED) is installed. Although an LED is used here as the illumination light, a fiber optic bundle consisting of a bundle of optical fibers can also be used. <Beziehung zwischen dem Spitzenteil und dem gekrümmten Teil des Einweg-Endoskopgeräts>

[0027] Fig. Figure 4 is a perspective view showing the relationship between the tip part 101 and the curved part 102 of the disposable endoscope device. 10 as shown in the present embodiment. Fig. 4 The curved part 102 has a clamping opening 102a, an air / water supply opening 102b and a water jet opening 102c at its front end. The clamping opening 102a, the air / water supply opening 102b and the water jet opening 102c are several channels provided on the curved part 102, i.e. openings at the end of a clamping channel, an air / water supply channel and a water jet channel respectively.

[0028] The curved part 102 has a contacted power supply connector 102d and a signal connector 1002e at its front end. The power supply connector 102d is connected, for example, via a power cable that runs through the cable channels of the soft part 103 and the curved part 102 to a power supply terminal of the connector part 106. The signal connector 102e is connected, for example, via a signal cable that runs through the cable channels of the soft part 103 and the curved part 102 to a signal terminal of the connector part 106.

[0029] The tip part 101 is connected to a cylindrical main body part 101a, a clamping opening 101b provided on the main body part 101a, an air / water supply opening 101c, a water jet opening 101d, and an LED light 101e (corresponding to the lighting element). 14 in Fig. 5, which also applies below) and an imaging unit 101f (corresponding to the image sensor) 13 in Fig. 5, which also applies below). The tip section 101 further comprises a power supply connection (power supply pin) 101g and a signal connection (signal pin) 101h at the rear end of the main body section 101a, which is connected to the front end of the curved section 102. The power supply connection 101g is, for example, connected to the LED light 101e and the image sensor 101f. By inserting and connecting the power supply connection 101g to the power supply connection 102d at the front end of the curved section 102, it is possible to supply power to the LED light 101e and the image sensor 101f.

[0030] The signal pin 101h is connected, for example, to the image sensor 101f. By inserting and connecting the signal pin 101h to the signal connector 102e at the front end of the curved part 102, it is possible to output an image signal from the image sensor 101f via a signal cable to the signal port of the connector part 106. The connection for outputting the image signal from the image sensor 101f can also be changed to a wireless connection, such as Bluetooth (registered trademark).

[0031] The joint between the pointed part 101 and the curved part 102 is covered by a tubular fragment 107. The material for the fragment 107 can be, for example, a flexible and compliant resin, just like the resin that forms the curved part 102 and the soft part 103. The fragment 107 covers not only the joint between the pointed part 101 and the curved part 102, but also, for example, the rear end of the main body part 101a of the pointed part 101 adjacent to the joint and the pointed part of the curved part 102. The fragment 107 is, for example, glued or joined to the rear end of the pointed part 101 and the pointed part of the curved part 102 and then breaks when the pointed part 101 is removed from the curved part 102.

[0032] With the endoscope 10In the present embodiment, the removal of the pointed part 101 by an unauthorized third party can be prevented by the fragment 107. Even if the pointed part 101 is removed from the curved part 102, it is readily apparent, due to the broken fragment 107, that the pointed part 101 has been removed. <Interner funktioneller Aufbau des Einweg-Endoskopgeräts 10, des Relaisadapters 40 und des Prozessors 20 für das Wiederverwendungsendoskop>

[0033] Fig. Figure 5 is a block diagram showing the internal functional structure and electrical connection (signal flow) in the state in which the disposable endoscope device is 10 and the processor 20 for the reusable endoscope with the relay adapter 40 are connected. Example of an internal functional structure of the disposable endoscope device 10

[0034] The disposable endoscope device 10is equipped with: a control unit (CPU: Central Processor Unit) 11 , which controls the operation of the entire device, a memory that stores the self-information of the disposable endoscope device 10 stores (e.g., information including model name, serial number, white balance information, signal format used in various processing operations such as image processing, or control signal format (e.g., information about the voltage value of the ON or OFF voltage) when a control button is pressed (e.g., EEPROM: this information is stored during the manufacture of the disposable endoscope device). 10 (stored in EEPROM) 12 , an image sensor 13 , which captures an object being observed, and a lighting element 14 , such as an LED that emits light onto the object being observed. As an image sensor 13For example, a CMOS image sensor is used, which captures images in a high-resolution HD format (High Definition: 1,000,000 pixels or more). The control unit 11 recognizes that the disposable endoscope device 10 with the relay adapter 40 is connected and receives its own information from the disposable endoscope device. 10 from the storage 12 and transmits this to the relay adapter 40 Alternatively, the relay adapter can be used. 40 the connection of the disposable endoscope device 10 detect, a command signal to send the self-information to the connected disposable endoscope device 10 transferred and the control part 11 can respond appropriately to the relay adapter's own information. 40 Return it. This will allow the relay adapter to be returned. 40 Information regarding the specifications of the disposable endoscope device 10 receive. (ii) Example of an internal functional structure of relay adapter 40

[0035] The relay adapter 40 is equipped with: a control unit 41 , which controls the overall operation of the relay adapter 40 and controls at least part of the operation of connected devices (e.g. relay control, connection assessment, etc.), a lighting I / F (interface) circuit 42 , which determine the light intensity of the lighting element 14 responding to a command from the control unit 41 changes, an imaging I / F circuit 43 , which is the format of the image sensor 13 received video signal responds to a command from the control unit 41 converts to a display I / F circuit 44, which responds to a command from the control unit 41 a predetermined piece of information on a relay adapter 40 the intended (not shown) display section, and a communication section. 45, responding to a command from the control unit 41 a predetermined piece of information to the server 50 sends. The relay adapter 40 is also equipped with a storage component (storage device such as a memory: in Fig. 5 (not shown) for storing various data and parameters, operating programs, etc.

[0036] If a predetermined device (the shape of the plug part) 40 can be designed in such a way that only the processor 20 (for the reusable endoscope or the processor for the disposable endoscope) with a second connector part 47 of the relay adapter 40 When connected, the control unit communicates 41 with the connected device and recognizes the type of connected device. If the control unit 41 recognizes that the processor 20 For the reusable endoscope, the control unit requires 41the processor 20 for the reuse endoscope, its own information (e.g. information including model name, serial number, signal format used in various processing such as image processing, or control signal format (e.g. information about the voltage value of the ON or OFF voltage) when a control button is pressed) to the relay adapter 40 to send (request signal for sending specification information). The control unit 41 receives the above self-information, which is provided by the processor. 20 (System control unit) 21 ) for the reuse endoscope responding to the request, and stores the information in internal memory or external memory (not shown).

[0037] If the disposable endoscope device 10 with a first plug part 46 of the relay adapter 40 When connected, the control unit communicates 41with the disposable endoscope device 10 and receives, as described above, information from the disposable endoscope device itself. 10 . This gives the control unit 41 the respective self-information of the connected disposable endoscope device 10 and the processor 20 for the reusable endoscope and can recognize the difference in the specifications of the two devices.

[0038] The imaging I / F circuit 43 The processing involves converting the format of the data from the image sensor. 13 received video signal, e.g. from HD (2K, 4K, 8K etc.) to SD (Standard Definition) or from NTSC to PAL format under the control of the control unit 41 through. Furthermore, the imaging I / F circuit assesses 43The brightness of the received video signal, and if the brightness is below the lower limit (darker) of the specified range (if the brightness is within this range, it is considered adequate), the imaging I / F circuit outputs 43 a command to the lighting I / F circuit 42 The imaging I / F circuit outputs a signal to brighten the illumination, and if it is greater than the upper limit of the specified range (brighter), it outputs a signal to the oscillator. 43 a command to the lighting I / F circuit 42 off, to dim the lighting. The lighting I / F circuit 42 , which receives this command (which is via the control unit) 41 or directly from the imaging I / F circuit 43 (can be received), sends a control signal to the disposable endoscope device 10 , to adjust the brightness of the lighting element 14to change in response to the command. However, if the instruction to increase light intensity comes from the imaging I / F circuit. 43 is received and the lighting element (LED) 14 When the lighting light is already shining at maximum intensity, the lighting I / F circuit sends 42 the information to the imaging I / F circuit 43 This means that the lighting is already controlled at maximum light intensity and cannot emit light at a higher intensity. Alternatively, if the lighting begins emitting at maximum light intensity, the information about the start of emission at maximum light intensity can also be received from the lighting I / F circuit. 42 to the imaging I / F circuit 43 be sent. This enables the imaging I / F circuit. 43 , the emission control situation of the light from the lighting element 14to know. If, in this situation, the imaging I / F circuit 43 If it is determined that the brightness of the video signal is insufficient, processing to electrically brighten the video signal is performed and output.

[0039] The display I / F circuit 44 The predetermined information to be displayed on the display unit (not shown) is received from the control unit. 41 and displays the predetermined information on the display unit in response to a command from the control unit. 41 The displayed predefined information may include, for example: model name and serial number of the device with the relay adapter. 40 connected disposable endoscope device 10, Patient identification information / name and user identification information / name (e.g., the operator can enter the information from an input area not shown before observation or operation), and model name and serial number of the device with the relay adapter 40 connected processor 20 for the reuse endoscope or signal format information to be used, as well as the strength of the illumination light (light intensity) and the voltage situation of the power supply (voltage value, operating voltage value of the power supply).

[0040] The communication part 45 For example, it receives the specified information from the control unit. 41 to an external server 50 or an external storage device (not shown) is to be sent and held, and sends the specified information responsively to a command from the control unit. 41The predefined information to be sent includes, for example: the device's own information (model name and serial number) 10 , which will be used or has been used in the future, the place of use (hospital identification information / name, location, etc.), the date and time of use, the patient identification information / name, information indicating that the device has already been used, the user identification information / name, etc.

[0041] Although not shown, the relay adapter 40 It may also be equipped with an input device such as a control button, a joystick, a touchscreen, etc. This allows for functions specific to the disposable endoscope device. 10 are and not from the processor 20 for the reuse endoscope can be controlled (e.g. a function with which only a central part of the image sensor is controlled). 13(recorded image is used), via the relay adapter 40 to be operated and controlled. (iii) Example of an internal functional structure of processor 20 for the reuse endoscope

[0042] The processor 20 The reusable endoscope is equipped with: the system control unit 21 , which controls the operation of the entire processor 20 for the reusable endoscope, a video signal processing unit 22 , which uses the relay adapter 40 received video signal responding to a command from the system control unit 21 processed, a video display part 23 , which is from the video signal processing part 22 displays processed video signal, and a power supply 24 , which supplies power to the device.

[0043] The system control unit 21For example, it sends specification information in response to the request signal from the control unit. 41 of the relay adapter 40 is received, internal information of the processor 20 for the reuse endoscope (e.g. information including model name, serial number, signal format used in various processing operations such as image processing, or control signal format (e.g. information about the voltage value of the ON or OFF voltage when a control button is pressed) to the relay adapter 40 The system control unit 21 Furthermore, it performs various control functions, such as issuing instructions to the video signal processing unit to change the display format, resolution, etc. of the video image. 22 according to the instructions entered by the operator.

[0044] The video signal processing section 22decompresses (decodes) the compressed data, for example, when the data is from the relay adapter. 40 The received video signal is compressed (encoded). Furthermore, if, for example, an instruction is given (e.g., an operator gives the instruction via the processor's control panel), the video signal is compressed (encoded). 20 a) to change the resolution of the system control unit 21 The video signal processing section performs the following steps when the signal is received. 22 a data interpolation processing (interpolation) or a decimation processing for the data from the relay adapter 40 receives the video signal and passes it on to the video display unit. 23 out of.

[0045] The system can also be designed in such a way that the power supply 24 not just the processor 20 not only powers the reusable endoscope, but also the relay adapter 40 or the disposable endoscope device 10 supplied with power. In this case, the relay adapter uses40 the power supply from the processor 20 The reusable endoscope not only supplies power to itself, but also directs the power supply to the disposable endoscope device. 10 next. If the relay adapter 40 and the disposable endoscope device 10 If they are equipped with a power supply, this can also be designed in such a way that a secondary power supply can be provided from the power supply unit. 24 will be delivered. <formatanpassungsverarbeitung>

[0046] Fig. Figure 6 is a flowchart illustrating a format adaptation process according to the present embodiment. In this description, the format adaptation process refers to a process for assessing whether the format for the disposable endoscope device is suitable. 10 used signal format and that for the processor 20 The signal format used for the reusable endoscope may or may not be different, and if the two are different, processing is required to adapt them. Each step of this flowchart is explained below, assuming the control section 41 of the relay adapter 40 (hereinafter referred to simply as "Control Unit 41") is mainly operated. Step 601

[0047] If the disposable endoscope device 10 with the first plug part 46 of the relay adapter 40 When connected, the control unit communicates 41 with the control unit 11 of the disposable endoscope device 10 mutually and requests the transmission of the self-information of the connected disposable endoscope device. 10 to (request for sending own information (specification information)). The control part 11 of the disposable endoscope device 10 sends the self-information to the control unit 41 Responding to the request to send proprietary information. Proprietary information includes, for example, information about the disposable endoscope device. 10 , which are in storage 12 of the disposable endoscope device 10 Stored data includes model name, serial number, white balance information, signal format used in various processes such as image processing, and control signal format (e.g., information about the voltage value of the ON or OFF voltage) when a control button is pressed. This allows the relay adapter to 40 , to capture the signal format, etc., from the connected disposable endoscope device 10 is used. (ii) Step 602

[0048] The control unit 41 points to the communication part 45 at least the identification information (serial number) of the disposable endoscope device 10 , which are contained in the proprietary information provided by the disposable endoscope device 10 will be obtained, as well as information indicating that the disposable endoscope device 10 was used (e.g., flag used: it is also possible to base this on the receipt of identification information from the server). 50 (to generate and manage the flag used) to the server 50 to send. The communication part 45 at least transmits the identification information of the disposable endoscope device. 10 and the information of the flag used, responding to the instruction over the network 60 to the server 50 If the relay adapter 40 is located in an environment where the network 60 If the control unit is inaccessible, it may be inaccessible. 41 Store the identification information and the information of the flag used once in a memory area (not shown) and send the transmission to the server. 50 repeat at the time it enters the network environment.

[0049] Although the servers are connected to this 50 Information to be sent: the identification information of the disposable endoscope device 10 and the information of the flag used, can also include the model name of the disposable endoscope device. 10 , Patient identification information / name, user identification information / name, etc. to the server 50 to be sent. The destination is not a remotely installed server. 50 (e.g. a cloud server, etc.) is not limited, but can be, for example, a storage device installed in a hospital.

[0050] As explained above, the disposable endoscope device 10 , once this is used on the server 50 Registered as already used (preferably including date and time of use). Therefore, if an attempt is made to use the disposable endoscope device 10 To reuse with the same identification information (serial number), the reuse of the already used disposable endoscope device is possible. 10 This can be prevented by controlling the processor in such a way that... 20 for the reuse endoscope is no longer operated, or by a display part (not shown) of the relay adapter 40 It indicates that it has been used. Although the tip part 101 in the disposable endoscope device 10 When the disposable endoscope device is reused, it will be reconstructed. 10 using the reused tip, the new identification information (serial number) is stored in the internal memory of the control unit (CPU). 11 overwritten (In a factory for the reconstruction (reassembly) of the disposable endoscope device). (iii) Step 603

[0051] If the processor 20 for the reusable endoscope with the second connector part 47 of the relay adapter 40 When connected, the control unit communicates 41 with the system control unit 21 of the processor 20 mutually and requests the transmission of the connected processor's own information. 20 to (request to send self-information (specification information)). The system control unit 21 of the processor 20 For the reusable endoscope, the specification information is sent to the control unit. 41 Responding to the request to send the specification information. This includes, for example, information about the processor itself. 20 for the reuse endoscope, including model name, serial number, signal format used in various processing operations such as image processing, or control signal format (e.g., information about the voltage value of the ON or OFF voltage) when a control button is pressed. The control unit 41 receives the aforementioned proprietary information, which is provided by the system control unit. 21 responding to the request to send the specification information, and stores the information in internal or external memory (not shown). (iv) Step 604

[0052] The control unit 41 compares the information obtained in steps 602 and 603 and records the difference in signal formats (video signal formats and formats of a control signal (H (ON) and L (OFF) voltage levels by pressing the control unit button)) required for the disposable endoscope device 10 and the processor 20 for use in the reusable endoscope. Based on the differences in signal format, the control unit determines 41 then the processing content of the signal conversion, into which arbitrary video format the signal from the disposable endoscope device can be converted. 10 The captured video signal is converted (e.g., HD to SD), including the amount of the voltage level setting of H and L, and the processing content is stored in a non-displayed memory (memory part). Step 605

[0053] When the object being observed is viewed through the image sensor 13 of the disposable endoscope device 10 The control unit checks when the recording is complete and the corresponding video signal is received. 41 The processing content of the signal conversion, stored in an unspecified memory, converts the corresponding video signal so that it matches the one provided by the processor. 20 The format used for the reusable endoscope is compatible, and the video signal is sent to the processor. 20 for the reusable endoscope.

[0054] The control unit 41 It also converts an endoscope control signal (e.g., electronic shutter control of the image sensor). 13 etc.) from the processor 20 for the reusable endoscope into a signal format that is compatible with the disposable endoscope device 10 can be detected, and sends the converted signal to the disposable endoscope device. 10 off. So, for example, if an operator is at the processor's control panel 20 When a freeze-frame mode is selected for the reuse endoscope, the corresponding control signal is sent to the relay adapter. 40 sent. In this case, the control unit 41 a signal (command) to the disposable endoscope device 10 in a signal format that is output by the control unit 11 can be detected to use the image sensor 13 to control it in such a way that it records an observed object with a shorter shutter speed (e.g. 1 / 250 s) than normal (1 / 60 s or 1 / 30 s). <Verarbeitung bei einer Tastenbetätigung im Einweg-Endoskopgerät>

[0055] For example, if the disposable endoscope device 10 the processor changes the signal level from low (OFF) to high (ON) as soon as the operating button is pressed 20 For the reusable endoscope, it may be necessary to recognize low as ON and high as OFF. In such a case, the intended operation is completely reversed, so the signal format must be converted. (This applies to the disposable endoscope device.) 10 Furthermore, a large number of control buttons may be present, and the levels of the signals generated by pressing a control button can be configured as Level_1, Level_2, and Level_3. Since the processor 20 However, since the reuse endoscope may not be able to process the signals unchanged, it must determine the operator's intention (i.e., which operation the pressed button corresponds to with the instruction), and the signal must be converted into a signal format that the processor can interpret. 20 It can be processed for the reusable endoscope. Such a conversion processing of the signal format is the processing during button presses in the disposable endoscope device. 10 .

[0056] Fig. Figure 7 is a flowchart illustrating the processing content in the relay adapter. 40 , when the operating button of the control unit 104 of the disposable endoscope device 10 is activated. Step 701

[0057] The control unit 41 determined on the basis of the disposable endoscope device 10 The received signal indicates whether the operating button of the control unit 104 is pressed. If the operating button is pressed (if YES in step 701), processing proceeds to step 702. If the operating button is not pressed (in the case of NO in step 701), the control unit 41 the surveillance continues. (ii) Step 702

[0058] The control unit 41 compares the signal format used in the disposable endoscope device 10 The key press used corresponds to the signal format provided by the processor. 20 for the reuse endoscope, which were obtained in steps 602 and 604. (iii) Step 703

[0059] The control unit 41 assesses whether, as a result of the comparison processing in step 702, the signal format that is in the disposable endoscope device 10 corresponds to the key press used, and the signal format that is generated by the processor 20 The data required for processing the reusable endoscope must be different. If they are the same (if NO in step 703), processing proceeds to step 705. If they are different (if YES in step 703), processing proceeds to step 704. (iv) Step 704

[0060] The control unit 41 converts the button press signal in the disposable endoscope device 10 based on the processing content of the signal conversion determined (generated) in step 604, so that the processor 20 for the reusable endoscope, the button activation signals in the disposable endoscope device 10 can recognize (format conversion). In this case, the processing content of the signal conversion represents a processing content in which each operating button in the disposable endoscope device 10 This corresponds to an action (a correspondence between the key press and the processing content). This allows the processor to 20 For the reusable endoscope, the processing is carried out according to the instructions for the disposable endoscope device. 10 Execute the pressed button exactly. Step 705

[0061] The control unit 41 sends a signal equivalent to pressing a button on the disposable endoscope device 10 corresponds (the content of the processing that corresponds to the key press), to the processor 20 for the reusable endoscope. <Verarbeitung in einem Fall, in dem ein Steuersignal für eine Weißabgleicheinstellung empfangen wird>

[0062] The disposable endoscope device 10 This occurs, for example, in the state where the white balance between the image sensor 13 and the lighting element 14 The white balance is set and its contents are stored in internal memory (with fixed white balance) and is delivered from the factory. Therefore, the relay adapter 40 The white balance cannot be adjusted even if it receives a control signal for the white balance setting (a signal instructing the user to adjust the white balance, generated by the operator's operation of the control panel) from the processor. 20 for the reusable endoscope. If, on the other hand, it is from the relay adapter 40 If no response is given, even though a control signal for white balance adjustment has been sent, the processor sends 20 For the reusable endoscope, this control signal for white balance adjustment is still sent to the relay adapter. 40 ...and an unnecessary process will occur. The present processing serves to prevent such an unnecessary process from taking place.

[0063] Fig. Figure 8 is a flowchart to illustrate the processing in the case where the relay adapter 40 the control signal for white balance adjustment from the processor 20 for the reusable endoscope. Step 801

[0064] The control unit 41 assessed based on the processor 20 The signal received by the reuse endoscope determines whether the control signal for white balance adjustment is received. If the control signal for white balance adjustment is received (if YES in step 801), processing proceeds to step 802. If the control signal for white balance adjustment is not present in the signal from the processor, the process continues. 20 for the reusable endoscope (if NO in step 801), the control unit sets 41 the surveillance continues. (ii) Step 802

[0065] The control unit 41 sends a signal indicating a set white balance (the white balance OK signal) to the processor. 20 for the reuse endoscope, which indicates that the white balance is set, although the white balance of the image sensor 13 and the lighting element 14 In fact, it was not set. This way, an unnecessary process that would put a strain on the processor can be avoided. 20 For the reuse endoscope, the control signal for the white balance adjustment is still sent to the relay adapter. 40 sends. <Zusätzliche Erklärung und abgewandeltes Beispiel>

[0066] (i) In a normal (conventional) endoscope system (reusable endoscope), a system controller in the processor converts the video signal transmitted by the image sensor into YUV and checks the brightness of the video signal based on the Y (luminance) signal. If it is too dark or too bright, the light source in the processor is controlled to adjust the brightness to an appropriate level.

[0067] In contrast, in the present embodiment, the processor 20 If the light source provided for the reusable endoscope is not used, the control unit controls it. 41 (or the lighting I / F circuit) 42 ) of the relay adapter (pulse control or linear control) the lighting element (LED) 14 , which is located at the tip of part 101 of the disposable endoscope device 10 The system is designed so that if the object being observed is judged to be near, the illumination is dimmed, and if the object being observed is judged to be far away, the illumination is brightened. This ensures that the brightness of the captured image is constant. To prevent the light source from affecting the processor 20 The control unit, which is used for the reusable endoscope, provides information. 41 Therefore, for example, a dummy signal to the processor 20 for the reuse endoscope, which indicates that the brightness setting is unnecessary (without such a signal, the processing loop regarding the light source in the processor is omitted). 20 interrupted and caused the system control unit to malfunction. 21 (possibly sending unnecessary control signals to components such as motors and drivers, which can lead to abnormal operation), so that the lighting control in the processor 20 It doesn't work. The control unit 41 It also checks the light intensity of the video signal from the imaging I / F circuit. 43 , controls the lighting I / F circuit as needed based on the light intensity 42 and controls the lighting element (LED) (light intensity setting). 14 of the disposable endoscope device 10 through.

[0068] (ii) In the embodiment described above, for example the serial number (identification information) of the disposable endoscope device 10 to the server 50 sent, and the server 50 It tracks that the endoscope has been used, thus preventing its reuse. Instead or in addition, a disposable endoscope can be used. 10 However, it must be structurally (mechanically) designed in such a way that it cannot be reused. To achieve this, for example, if the disposable endoscope device... 10 with the relay adapter 40 or is connected to the processor for the disposable endoscope, the connector part 106 is designed such that when disconnecting, only the components in the connector part 106 of the disposable endoscope device 10 The intended plug pins (not shown) are broken (destroyed so that they cannot be reconnected): the connecting part of neither the relay adapter nor the intended plug pins are broken (destroyed so that they cannot be reconnected). 40 (even if a dedicated processor is used) will be affected.

[0069] (iii) In the present embodiment, when connecting the disposable endoscope device 10 with the relay adapter 40 whose serial number (identification information) is sent to the server 50 sent and managed. However, the serial number (identification information) can also be sent to the server. 50 will be sent when the disposable endoscope device 10 for a predetermined period of time with the relay adapter 40 is connected (e.g., the time required to insert the device into the patient's body (a predetermined time)). If the disposable endoscope device 10 before the end of a predetermined time period from the relay adapter 40 If removed, it can be reconnected using a new connection with the relay adapter. 40 be made available for use again, instead of being immediately managed as already used. If a disposable endoscope device 10 within a short time from the relay adapter 40 Once the endoscope is withdrawn, it is considered withdrawn before it is inserted into the patient's body. This is because it would be a waste of material and resources to assume that the endoscope would be uniformly considered already used in such a case.

[0070] (iv) The relay adapter 40 This can be achieved, for example, by enclosing each component in a box-shaped housing. In this case, as in Fig. Figure 5 shows a structure with the first plug part 46 and the second plug part 47 as a relay adapter 40 can be adopted, however the middle part of one or both plug parts can be a connecting cable structure.

[0071] The possibility that an operator (e.g., a doctor) may accidentally touch the relay adapter during an examination using an endoscope 40 It cannot be ruled out that the first part of the plug may be touched. 46 , the second part of the plug 47 and the case is provided with a waterproof structure.

[0072] (v) The disposable endoscope device 10 can also be used without a lighting element (light source) 14 be trained. In this case, the light emitted by the light source (not shown) is processed by the processor. 20 The signal intended for the reusable endoscope is projected onto the object being observed. To achieve this, the relay adapter can be used. 40 as an additional component, it includes an LCB (Light Cable Bundle) and a structure that connects it to the disposable endoscope device. 10 and the processor 20 for the reusable endoscope connects (e.g. the first plug part) 46 and the second plug 47 of the relay adapter 40 (each is equipped with a connection point of the LCB). In this case, the light from the light source is in the processor. 20 via the LCB of the relay adapter 40 for the disposable endoscope device 10 This is because the light source is directed by the processor in this way. 20 When used, it is not necessary to obtain the aforementioned blind or OK signals from the relay adapter. 40 to the processor 20 to output. If the relay adapter 40 In this way, the light source can be trained in the processor. 20 can be used unchanged for the reusable endoscope. <Zusammenfassung der Ausführungsform> (i) In this embodiment, the control part receives 41 of the relay adapter the first specification information (information about the video signal format information that the endoscope device 10 used, or the signal level corresponding to the operating button), including the content of the signal processing in the endoscope device (e.g. disposable endoscope device) and the second specification information (information about the video signal format information provided by the processor). 20 The signal level corresponding to the operating button can be detected, including the content of the signal processing in the processor. The control unit 41 The system compares the first specification information with the second specification information, converts the signals received by the endoscope (video signals and button press signals) based on the results of the comparison, so that the processor (e.g., the processor for a conventional reusable endoscope) can process the signals, generates the converted signals, and then outputs the converted signals to the processor. In this way, it is possible to ensure the consistency of the signal format within the endoscope. 10 and in the processor 20 to ensure this. Therefore, the processor will be able to process the signals, data, and information from the endoscope device. 10 to process. (ii) The relay adapter 40 It further comprises an illumination I / F section, which is provided in the endoscope device and outputs a control signal to an illumination element functioning as a light source, and an imaging I / F section, which is provided in the endoscope device and outputs a control signal to an image sensor that captures an image of an object under observation. The control section 31 outputs a dummy signal to the processor. 20 off, which indicates that the brightness setting in the processor 20 The included light source is unnecessary. This prevents errors in the light source control operation within the processor. 20 is caused. (iii) If the control part 41 a control signal for white balance adjustment from the processor 41 receives the white balance setting of at least one of the devices in the endoscope. 10 included image sensor 13 or lighting element 14 Since the white balance value is fixed upon delivery, a signal for the set white balance (OK signal) is also sent to the processor. 20 The output indicates that white balance has been set, without actually performing the white balance adjustment. This makes it possible to monitor the processor's operation. 20 to ensure this. In other words, it will be possible to avoid the occurrence of unnecessary operation in which the processor 20 the control signal for the white balance setting is still sent to the relay adapter 40 sends. (iv) The relay adapter 40 is equipped with an input device (e.g., a control button, a joystick, a touchscreen, etc.) for entering instructions to control the functions of the endoscope device. 10 equipped. The control unit 41 activates and controls a device for the endoscope 10 specific function responding to instructions entered by the input part. It cannot, for example, be performed by the processor. 20 , however, from the relay adapter 40 can be controlled, such as a processing to activate the function, with which only the central part of the image sensor is used. 13 The recorded image is used and carried out. (v) The relay adapter 40 is also equipped with a communication component 45 equipped to facilitate communication with an external server 50 via the network 60 This enables the use of a disposable endoscope device. 10 with the first plug part 46 of the relay adapter 40 When connected, the communication part sends 45 at least the identification information (that is provided by the control unit) 41 (is obtained) of the disposable endoscope device 10 to the server 50 This allows it to be connected to the relay adapter. 40 connected disposable endoscope device 10 The relay adapter can be managed centrally as already used. 40 receives from the server 50 about the communication part 45 also endoscope management information indicating whether the identification information of the disposable endoscope device to be used is required. 10 The control part 41 It then determines, based on the endoscope management information, whether the use of the disposable endoscope device is permissible. 10 , the one with the first plug part 46 This is intended to be permitted. This reduces the risk of reusing the already used disposable endoscope device. 10 avoided. <Spezifische Merkmale der vorliegenden Offenbarung> Specific characteristic 1
