[Overview of the invention]

[Problem to be solved by the invention]

However, Patent Document 1 only discloses a relay cable adapted to different connector shapes between a reuse endoscope and a disposable endoscope. So, if the signal format is common between the reuse endoscope and the single-use endoscope, or if the signal formats of the two endoscopes are different, it is necessary to convert the signal format to a signal format that the processor (which normally corresponds to the format of a signal output from the reuse endoscope) can be processed in a single-use endoscope. Although it is desirable to keep the cost as low as possible since the single-use endoscope is assumed to be used once, the cost of the single-use endoscope becomes higher when the signal format conversion processing can be performed as the scale of the circuit becomes larger and the number of components is increasing.

[Embodiments of the Invention]

The present embodiment relates to a relay adapter that enables a disposable (i.e., "single use") endoscope to be connected and used with a processor for a reuse endoscope, and 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.

<Formation of the endoscope system>

1 shows a schematic embodiment example of an endoscope system 1 according to the present embodiment. This in 1 illustrated endoscope system 1 is with a single-use endoscope device 10 , a processor 20th for a reuse endoscope, a monitor 30th , a relay adapter 40 and a server 50 connected over a network to the relay adapter 40 connected is. The relay adapter 40 is connected to a plug part 106 of the single-use endoscope device 10 and a connector part 201 of the processor for the reuse endoscope.

The relay adapter 40 is a device for connecting the single-use endoscope device 10 with the processor 20th for the reuse endoscope, and has, for example, a function that regardless of whether there is a mismatch in the physical shape of the two connectors (if there is a physical mismatch, a structural connection can also be guaranteed), a mismatch between a signal format (video and control signal format ) for the single-use endoscope device 10 is used and a signal format eliminated by the processor 20th can be processed for the reuse endoscope.

The endoscope system 1 according to the present embodiment is also with the server 50 provided that over a network 60 with the relay adapter 40 connected to the server 50 however, it 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 single-use endoscope device 10 ) to rent. If a server 50 is installed, is the server 50 for example designed in such a way that on the server 50 can be accessed from a computer, not shown, and which is on the server 50 held data can be searched. So when using the single-use endoscope device 10 a serial number (identification information) of the endoscope device to the server 50 to determine in advance whether or not the endoscope device has been used.

The single-use endoscope device 10 comprises: a tip part 101 with an imaging part which is inserted inside an examination subject (not shown), a curved part 102 which curves inside the examination subject can be operated, a slender tubular soft part 103, an operating part 104 which is connected to the soft part 103 and is operated by a user (operator), a plug cable part 105 which extends from the operating part 104 and with the relay adapter 40 is connected, and a connector part 106, one with the relay adapter 40 represents connected part. The endoscope 10 According to the present embodiment, it can also be designed such that a portion from the curved part 102 to the plug part 106 is used once, and only the tip part 101 or the imaging part included in this tip part 101 (for example, an element (e.g. a resin member) that houses an image sensor, removes and exposes the image sensor) from the endoscope 10 separated, cleaned and reused (see 2 ). The tip part 101, the curved part 102, and the soft part 103 may collectively be referred to as an insertion part. Here, the boundary between the reused part and the disposable part is regarded as the boundary between the tip part 101 and the curved part 102, but the boundary may also be a predetermined position on the path of the curved part 102 or a predetermined position on the path of the soft part 103 be.

The part of the single-use endoscope device 10 which is inserted into the body of the examination subject consists of the tip part 101, the curved part 102 which is coaxially connected to the soft part 103 and is made 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 in shape.

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 contain a treatment device -Inlet channel, two air / water supply hoses, a secondary water supply hose and a spiral or hose-shaped guide tube (which can be designed in such a way that it contains a tightly wound coil of guide metal) through which an angle wire is passed. In addition, an optical fiber bundle can be installed for lighting.

As in 1 As shown, the operating part 104 has an operating part body 104a, which forms an operating and grip part, and a treatment device insertion opening 104c, which is provided near the soft part 103 of the operating part body 104a. The treatment device insertion port 104c is an opening of the above-mentioned treatment device insertion channel on the side of the operation part 104. On the operation part body 104a, there are a curvature operating button 104b for operating a curvature of the curved part 102 and a switch, etc. related to operation of the endoscope 10 intended.

The processor 20th for the reuse endoscope is an apparatus for processing image data generated by the imaging part (image sensor 13th ), which is in the tip part 101 of the single-use endoscope device 10 is included, added by the relay adapter 40 subjected to predetermined signal processing and transmitted through the imaging signal cable, and for generating a video signal. The processor 20th for the reuse endoscope forwards the generated video signal to the monitor 30th out. This creates an internal image of the recorded examination object on the monitor 30th displayed.

<Overall structure of the single-use endoscope device 10 >

Although the single-use endoscope device 10 also in 1 has been explained, it is explained in more detail here. 2 illustrates the overall external structure of the single-use endoscope device 10 . In 2 the position and shape of the operating part 104 may differ from the actual position and shape due to the illustration in the drawing.

The single-use endoscope device 10 is provided, for example, with the tip part 101, the curved part 102, the soft part 103, the operating part 104, the plug cable part 105 and the plug part 106. Except for the tip part 101, the curved part 102, the soft part 103, the operating part 104, the plug cable part 105 and the plug 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 male cable part 105 are used, is preferably a multi-lumen structure. Examples of such highly flexible resins are: PTFE (polytetrafluoroethylene), ePTFE (expanded PTFE), PE (polyethylene), HDPE (high-density polyethylene), PP (polypropylene) (these are porous materials), PU (polyurethane), PP (polypropylene) ), PE (polyethylene), polyamide (polyamide) (these are non-porous materials). In the single-use endoscope device 10 For example, parts and elements other than those offered for reuse, such as an image sensor included in the tip part 101, and metal parts and elements used in conventional endoscopes can be largely replaced with resin elements.

The tip part 101 comprises, for example: an image sensor such as CMOS or CCD, a small LED as illumination, a memory (this can be a memory built 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 distribution lens attached to the LED, a forceps opening, an air supply opening (replacement for an air supply nozzle in a conventional endoscope), a water supply opening (replacement for a water supply nozzle in a conventional endoscope) Endoscope), and a water jet opening. The tip part 101 is formed by being coated with a resin that is harder and less deformable than other parts of the single-use endoscope device 10 , the image sensor, the small LED, the memory, etc. In this case, the parts corresponding to the nozzle (air and water supply nozzles) and the lens for illumination are preferably molded integrally with the tip part 101 by the 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 connected by an adhesive such as an adhesive tape or a bonding agent, and are configured so that a user (e.g., a hospital doctor) does not see the tip part 101 from the endoscope 10 can separate. It can also be designed in such a way that when the tip part 101 of the endoscope 10 is separated, the separation is a part (e.g. the internal structure or the structure of the attachment part on the endoscope 10 ) deform or damage the tip portion 101 and prevent the user from reusing the tip portion 101. The image sensors and small LEDs housed in the tip part 101 have the same characteristics as those housed 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 etc. incorporated therein are supplied by the manufacturer or specialist of the endoscope 10 cleaned and offered for reuse after the single-use endoscope device 10 being picked up from the hospital. Apart from the tip part 101, the curved part 102, the soft part 103, the operating part 104 and the connector cable part 105 are disposed of (for example, incinerated). In other words, with the cleaned and sterilized tip part 101 as well as a completely new, curved part 102, soft part 103, operating part 104 and plug-in cable part 105, a new single-use endoscope device becomes 10 and made available to the hospital again.

As described above, the curved portion 102 is entirely made of resin. For example, the curved part 102 is preferably made of resin having a multi-lumen structure. In the curved part 102, as shown in FIG 2 As shown, a resin hose which forms a pincer pipe, a resin hose which forms an air supply pipe, a resin hose which forms a water supply pipe, and a resin hose which forms a sub-water supply pipe protrude from the end face of the curved part 102. If the illuminating light is introduced through an optical fiber rather than an LED, an optical fiber bundle for the illumination also protrudes from this end face. Each of the four resin tubes is inserted into each of the insertion openings (forceps, air supply, water supply and water jet opening) 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.

The soft part 103 may be formed of, for example, a plastic spiral pipe or a resin having a multi-lumen structure. A metal sheet or wire is not inserted in the soft part 103, and instead, a resin tube, etc. having a higher hardness than the resin used for the outer part (skin part) of the soft part 103 is inserted. This makes it possible that only the curved part 102 can be curved. The built-in parts of the soft part 103 and the curved part 102 are electric cables for power supply, signal transmission and a switch in addition to the above resin wire (resin angle wire) or metal wire and the resin hoses with high hardness. In the case of wireless signal transmission, the built-in parts are e.g. a resin or metal angle wire, a resin coil, a line for the power supply (electrical cable), a line for the transmission of an electrical signal from a signal antenna installed in the soft part and a cable for a switch.

The operating part 104 is also preferably made entirely of resin. The operating part 104 is provided, for example, with the operating part body 104a, which forms the operating and grip part, an electrical switch 104b and a treatment device insertion opening 104c, which is provided on the side close to the soft part 103 of the operating part body 104a. The user (e.g. an operator such as a doctor) can operate the suction, air and water supply with the electrical switch 104b provided in the operating part 104, for example. Since the various operations can be switched with the electric switch 104b in this way, blow-out caused by backflow of mucus, blood, etc. can be completely prevented. The internal structure of the operating part 104 can also be integrally molded using slide injection molding, etc.

The male cable part 105 and the male part 106 are also made entirely of resin. The plug cable part 105 accommodates a part of the cable which extends from the operating part 104 to the tip part 101. The plug part 106 can also be a contain an electrical circuit or an electronic circuit. The plug part 106 may further be provided with, for example, a teat (made of resin), an air supply nipple (made of resin), a water supply nipple (made of resin), and a water jet opening.

<Front assembly of the tip part of the disposable endoscope device>

3 shows the front structure with the tip part 101 of the single-use endoscope device 10 . On the tip part 101, for example, there are arranged: an objective lens 31 of the imaging part (including an image sensor such as a CMOS or CCD), a forceps 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 port 34 to which a sub-water supply hose is attached, and a light distribution lens 35 to which illuminating light (LED) is installed. Although an LED is used as the illuminating light here, an optical fiber bundle consisting of a bundle of optical fibers can also be used.

<Relationship between the tip part and the curved part of the single-use endoscope apparatus>

4th Fig. 13 is a perspective view showing the relationship between the tip part 101 and the curved part 102 of the single-use endoscope apparatus 10 according to the present embodiment. In 4th the curved portion 102 has a forceps opening 102a, an air / water supply opening 102b, and a water jet opening 102c at the front end. The forceps opening 102a, air / water supply opening 102b and water jet opening 102c are a plurality of channels provided on the curved part 102, that is, openings at the end of a forceps channel, an air / water supply channel and a water jet channel, respectively.

The curved part 102 has a contacted power supply connector 102d and a signal connector 1002e at the front end. The power supply connector 102d is connected to a power supply terminal of the connector part 106 via, for example, a power cable which is passed through the cable ducts of the soft part 103 and the curved part 102. The signal plug 102e is connected to a signal connection of the plug part 106, for example, via a signal cable which is guided through the cable ducts of the soft part 103 and the curved part 102.

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

The signal pin 101h is connected to the image sensor 101f, for example. 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 of the image sensor 101f to the signal terminal of the connector part 106 via a signal cable. The connection for outputting the image signal of the image sensor 101f can also be changed to a wireless connection such as Bluetooth (registered trademark).

The connection point between the tip part 101 and the curved part 102 is covered by a tubular fraction 107. As the material for the fractional part 107, for example, a resin having flexibility and resilience can be used, as well as the resin that forms the curved part 102 and the soft part 103. The fraction 107 not only covers the junction between the tip part 101 and the curved part 102, but also, for example, the rear end of the main body part 101a of the tip part 101 adjacent to the junction and the tip part of the curved part 102 The end of the tip part 101 and the tip part of the curved part 102 are bonded or bonded, and then broken when the tip part 101 is removed from the curved part 102.

With the endoscope 10 In the present embodiment, removal of the tip part 101 by an unauthorized third party can be prevented by the break part 107. Even if the tip part 101 is removed from the curved part 102, because of the broken fraction 107, it is easy to determine that the tip part 101 has been removed.

<Internal functional structure of the disposable endoscope apparatus 10, the relay adapter 40 and the processor 20 for the reuse endoscope>

5 Fig. 13 is a block diagram showing the internal functional structure and electrical connection (signal flow) in the state in which the single-use endoscope apparatus 10 and the processor 20th for the reuse endoscope with the relay adapter 40 are connected.

Example of an internal functional structure of the single-use endoscope device 10

The single-use endoscope device 10 is provided with: a control unit (CPU: Central Processor Unit) 11 that controls the operation of the entire device, a memory that stores the self-information of the single-use endoscope device 10 stores (e.g. information including model name, serial number, white balance information, 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 button is pressed (e.g. EEPROM: this information are used in the manufacture of the single-use endoscope device 10 stored in EEPROM) 12th , an image sensor 13th that picks up an observation object, and a lighting element 14th such as an LED that emits the illuminating light onto the observation object. As an image sensor 13th For example, a CMOS image sensor is used that records images in a high-resolution HD format (High Definition: 1,000,000 pixels or more). The control part 11 recognizes that the single-use endoscope device 10 with the relay adapter 40 is connected, and receives self-information of the single-use endoscope device 10 from memory 12th and transmits them to the relay adapter 40 . Alternatively, the relay adapter 40 the connection of the single-use endoscope device 10 recognize a command signal to send the self-information to the connected single-use endoscope device 10 transferred and the control part 11 can respond to the self-information to the relay adapter 40 send back. This allows the relay adapter 40 Information regarding the specifications of the single-use endoscope device 10 receive.

(ii) Example of an internal functional structure of the relay adapter 40

The relay adapter 40 is provided 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 that is the light intensity of the lighting element 14th in response to a command from the control part 41 changes, an imaging I / F circuit 43 that is the format of the image sensor 13th received video signal in response to an instruction from the control part 41 converts to a display I / F circuit 44 in response to a command from the control section 41 a predetermined information on one in the relay adapter 40 provided (not shown) display part, and a communication part 45 in response to a command from the control section 41 predetermined information to the server 50 sends. The relay adapter 40 is also equipped with a storage part (storage device such as a memory: in 5 not shown) for storing various data and parameters, operating programs, etc.

When a predetermined device (the shape of the plug part 40 can be designed in such a way that only the processor 20th for the reuse endoscope or the processor for the single-use endoscope can be connected) with a second connector part 47 of the relay adapter 40 is connected, the control part communicates 41 with the connected device and detects the type of connected device. When the control part 41 detects that the processor 20th for the reuse endoscope is connected, the control part requests 41 the processor 20th for the re-use endoscope, its own information (e.g. information including the model name, serial number, signal format used in various processing such as image processing, or control signal format (e.g. information on the voltage value of the ON or OFF voltage) when an operation button is pressed) the relay adapter 40 to be sent (request signal for sending specification information). The control part 41 receives the above self-information provided by the processor 20th (System control part 21 ) for the reuse endoscope in response to the request, and stores the information in the internal memory or in the external memory (not shown).

When the single-use endoscope device 10 with a first connector part 46 of the relay adapter 40 is connected, the control part communicates 41 with the single-use endoscope device 10 and receives, as described above, self-information of the single-use endoscope device 10 . This gives the control section 41 the respective intrinsic information of the connected single-use endoscope device 10 and the processor 20th for the reuse endoscope and can tell the difference in the specifications of the two devices.

The imaging I / F circuit 43 performs the processing of converting the format of the image sensor 13th received video signal e.g. from HD (2K, 4K, 8K etc.) in SD (Standard Definition) or from NTSC in PAL format under the control of the control part 41 by. In addition, the imaging I / F circuit judges 43 the brightness of the obtained video signal, and if the brightness is below the lower limit (darker) of the predetermined range (if the brightness is within this range, it is judged to be appropriate), the imaging I / F circuit outputs 43 a command to the lighting I / F circuit 42 off to brighten the illumination, and if it is greater than the upper limit of the predetermined range (brighter), the imaging I / F circuit outputs 43 a command to the lighting I / F circuit 42 off to dim the lighting. The lighting I / F circuit 42 that receives this command (which is sent via the control unit 41 or directly from the imaging I / F circuit 43 can be received), sends a control signal to the single-use endoscope device 10 to adjust the brightness of the lighting element 14th in response to the command to change. However, if the instruction to increase the light intensity from the imaging I / F circuit 43 is received and the lighting element (LED) 14th If the illuminating light is already shining with the maximum light intensity, the Illumination I / F circuit sends 42 the information to the imaging I / F circuit 43 that the illuminating light is already controlled with the maximum light intensity and the light cannot emit with a higher light intensity. Alternatively, if the emission of the illumination light begins with the maximum light intensity, the information about the start of the emission with the maximum light intensity can also be provided by the illumination I / F circuit 42 to the imaging I / F circuit 43 be sent. This enables the imaging I / F circuit 43 , the irradiation control situation of the light of the lighting element 14th to know. If in this situation the imaging I / F circuit 43 determines that the brightness of the video signal is insufficient, processing for electrically brightening the video signal is performed and output.

The display I / F circuit 44 receives the predetermined information to be displayed on the display part (not shown) from the control part 41 and displays the predetermined information on the display part in response to an instruction from the control part 41 at. The specified information displayed may include, for example: Model name and serial number of the one with the relay adapter 40 connected single-use endoscope device 10 , Patient identification information / name and user identification information / name (for example, the operator can input the information from an input part not shown before the observation or operation), and the model name and serial number of the relay adapter 40 connected processor 20th for the reuse endoscope or signal format information to be used, as well as the strength of the illuminating light (light intensity) and the voltage situation of the power supply unit (voltage value, operating voltage value of the power supply unit).

The communication part 45 receives, for example, the specified information from the control part 41 to an external server 50 or an external storage device (not shown) are to be sent and held, and sends the predetermined information in response to a command from the controller 41 . The specified information to be sent includes e.g. B.: the intrinsic information (model name and serial number) of the single-use endoscope device 10 that is 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 representing that the device has already been used, the user identification information / Name etc.

Although not shown, the relay adapter 40 also be provided with an input part such as a control button, a joystick, a touch screen, etc. You can then use functions that are specific to the single-use endoscope device 10 are and not from the processor 20th for the reuse endoscope can be controlled (e.g. a function with which only a central part of the image sensor 13th captured image) through the relay adapter 40 operated and controlled.

(iii) Example of an internal functional structure of the processor 20 for the reuse endoscope

The processor 20th for the reuse endoscope is provided with: the system control section 21 that is the operation of the entire processor 20th for the reuse endoscope, a video signal processing part 22nd that does that through the relay adapter 40 received video signal in response to a command from the system controller 21 processed, a video display part 23 that the from the video signal processing part 22nd processed video signal and a power supply 24 that supplies power to the device.

The system control part 21 sends, for example, in response to the request signal for the sending of specification information, that from the control part 41 of the relay adapter 40 is received, the processor's own information 20th for the reuse endoscope (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 on the voltage value of the ON or OFF voltage) when an operation button is pressed) to the Relay adapter 40 . The system control part 21 also performs various controls such as issuing instructions for changing the display format, resolution, etc. of the video image to the video signal processing part 22nd according to the instructions entered by the operator.

The video signal processing part 22nd decompresses (decodes) the compressed data, for example that from the relay adapter 40 the received video signal is compressed (encoded). If, for example, an instruction (eg an operator gives the instruction via the control panel of the processor 20th a) to change the resolution of the system control part 21 is received, the video signal processing part performs 22nd a data interpolation processing (interpolation) or a thinning-out processing (decimation) for that from the relay adapter 40 received video signal and outputs it to the video display part 23 out.

The system can also be designed in such a way that the power supply 24 not just the processor 20th powered for the reuse endoscope, but also the relay adapter 40 or the single-use endoscope device 10 powered. In this case the relay adapter is used 40 the power supply from the processor 20th for the reuse endoscope not only for itself, but also routes the power supply to the single-use endoscope device 10 further. When the relay adapter 40 and the single-use endoscope device 10 are provided with a power pack, this can also be designed such that a secondary power supply from the power pack 24 is delivered.

<Format adjustment processing>

6th Fig. 13 is a flowchart showing format matching processing according to the present embodiment. In the present specification, the format adjustment processing refers to processing for judging whether it is for the single-use endoscope apparatus 10 signal format used and that for the processor 20th signal format used for the reuse endoscope are different or not, and if the two are different, processing for matching the two. Each step of this flowchart is explained below, assuming that the control part 41 of the relay adapter 40 (hereinafter referred to simply as “control part 41”) is mainly operated.

Step 601

When the single-use endoscope device 10 with the first connector part 46 of the relay adapter 40 is connected, the control part communicates 41 with the control part 11 of the single-use endoscope device 10 mutually and requests the transmission of the self-information of the connected single-use endoscope device 10 to (request to send self-information (specification information)). The control part 11 of the single-use endoscope device 10 sends the self-information to the control part 41 in response to the request to send the self-information. The self-information includes, for example, information from the single-use endoscope device 10 that are in store 12th of the single-use endoscope device 10 including model name, serial number, white balance information, signal format used in various processing such as image processing, or control signal format (such as information about the voltage value of the ON or OFF voltage) when an operation button is pressed. This enables the relay adapter 40 to acquire the signal format, etc. from the connected single-use endoscope device 10 is used.

(ii) step 602

The control part 41 assigns the communication part 45 at least the identification information (serial number) of the single-use endoscope device 10 contained in the self information received from the single-use endoscope device 10 will be obtained, as well as information indicating that the single-use endoscope device 10 was used (e.g. flag used: here it is also possible, based on the receipt of the identification information by the server 50 to generate and manage the flag used) to the server 50 to send. The communication part 45 sends at least the identification information of the single-use endoscope device 10 and the information of the flag used in response to the instruction via the network 60 to the server 50 . When the relay adapter 40 located in an environment where the network 60 is not accessible, the control section 41 the identification information and the information of the flag used are stored once in a memory part (not shown) and the transmission to the server 50 repeat at the time it enters the network neighborhood.

Although here the to the server 50 information to be sent is the identification information of the single-use endoscope device 10 and the information of the flag used, the model name of the single-use endoscope apparatus can also be added to them 10 , Patient identification information / name, user identification information / name, etc. to the server 50 be sent. The target is not on a remotely installed server 50 (e.g. a cloud server, etc.), but can e.g. be a storage device installed in a hospital.

As explained above, the single-use endoscope device 10 if this is used once, on the server 50 registered as already used (preferably including date and time of use). So when trying the single-use endoscope device 10 with the same identification information (serial number) can reuse the already used single-use endoscope device 10 can be prevented by controlling the processor 20th for the reuse endoscope is no longer operated, or by on a display part (not shown) of the relay adapter 40 indicates that it has been used. Although the tip part 101 in the single-use endoscope apparatus 10 is reused in a reconstruction of the single-use endoscope device 10 Using the reused tip, the new identification information (serial number) in the internal memory of the control part (CPU) 11 overwritten (In a factory of reconstruction (reassembly) of the single-use endoscope device).

(iii) step 603

When the processor 20th for the reuse endoscope with the second connector part 47 of the relay adapter 40 is connected, the control part communicates 41 with the system control part 21 of the processor 20th mutually and demands the sending of the self-information of the connected processor 20th to (request to send self-information (specification information)). The system control part 21 of the processor 20th for the reuse endoscope sends the specification information to the control part 41 in response to the request to send the specification information. The self-information includes, for example, information from the processor 20th for the reuse endoscope including the 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 an operation button is pressed. The control part 41 receives the above self-information from the system controller 21 in response to the request to send the specification information, and stores the information in the internal memory or the external memory (not shown).

(iv) step 604

The control part 41 compares the information obtained in steps 602 and 603 and detects the difference in signal formats (video signal formats and formats of a control signal (H (ON) and L (OFF) voltage levels by key operation of the operating part)) for the single-use endoscope 10 and the processor 20th can be used for the reuse endoscope. The control section determines based on the differences in the signal format 41 then the processing content of the signal conversion, into which any video format that is used by the single-use endoscope device 10 captured video signal is converted (e.g., HD to SD) including the amount of adjustment of the voltage level of H and L, and stores the processing content in an unillustrated memory (memory part).

Step 605

When the object to be observed through the image sensor 13th of the single-use endoscope device 10 is recorded and the corresponding video signal is received, the control part checks 41 the processing content of the signal conversion stored in a memory (not shown), converts the corresponding video signal so that it matches that of the processor 20th the format used for the reuse endoscope and outputs the video signal to the processor 20th for the reuse endoscope.

The control part 41 also converts an endoscope control signal (e.g. electronic shutter control of the image sensor 13th etc.) from the processor 20th for the reuse endoscope into a signal format that can be used by the single-use endoscope device 10 can be recognized and sends the converted signal to the single-use endoscope device 10 out. So if, for example, an operator at the control panel of the processor 20th selects a freeze mode for the reuse endoscope, the corresponding control signal is sent to the relay adapter 40 Posted. In this case the control part gives 41 a signal (command) to the single-use endoscope device 10 in a signal format that is sent by the control section 11 can be detected to the image sensor 13th in such a way that it records an observation object with a faster shutter speed (e.g. 1/250 s) than normal (1/60 s or 1/30 s).

<One-touch processing in the single-use endoscope device>

If, for example, the single-use endoscope device 10 changes the signal level from low (OFF) to high (ON) as soon as the operating button is pressed, the processor can 20th for the reuse endoscope, if necessary, recognize Low as ON and High as OFF. In such a case, the intended operation is completely reversed, so that the signal format needs to be converted. In the single-use endoscope device 10 there may also be a large number of control buttons, and the levels of the signals generated by pressing the control button can be configured as Level_1, Level_2 and Level_3. Because the processor 20th for the reuse endoscope, however, may not be able to process the signals unchanged, he must determine with what intention the operator performed the operation (ie what operation the pressed key corresponds to with the instruction), and the signal must be converted into a signal format that the processor can use 20th can be processed for the reuse endoscope. One such signal format conversion processing is the key operation processing in the single-use endoscope apparatus 10 .

7th Fig. 13 is a flowchart showing the contents of processing in the relay adapter 40 when the operating button of the operating part 104 of the single-use endoscope device 10 is operated.

Step 701

The control part 41 determined on the basis of the disposable endoscope device 10 received signal whether the operating button of the operating part 104 is operated. When the operation key is operated (when YES in step 701), the processing advances to step 702. If the operation key is not operated (if NO in step 701), the control part sets 41 surveillance continued.

(ii) step 702

The control part 41 compares the signal format to that in the single-use endoscope device 10 key actuation used corresponds to the signal format used by the processor 20th for the reuse endoscope obtained in steps 602 and 604.

(iii) step 703

The control part 41 judges whether, as a result of the comparison processing in step 702, the signal format that is that in the single-use endoscope apparatus 10 the key press used and the signal format used by the processor 20th for the reuse endoscope can be processed are different. If they are the same (if NO in step 703), the processing advances to step 705. If they are different (if YES in step 703), the processing advances to step 704.

(iv) step 704

The control part 41 converts the key actuation signal in the single-use endoscope device 10 on the basis of the processing content of the signal conversion determined (generated) in step 604, so that the processor 20th for the reuse endoscope, the key actuation signals in the single-use endoscope device 10 can recognize (format conversion). In this case, the processing content of the signal conversion is processing content in which each operation key in the single-use endoscope apparatus 10 corresponds to one operation (a correspondence relationship between the key operation and the processing content). This allows the processor 20th for the reuse endoscope, the processing corresponds to that on the single-use endoscope device 10 carried out exactly.

Step 705

The control part 41 sends a signal that corresponds to a button actuation in the single-use endoscope device 10 (the content of the processing corresponding to the key operation) to the processor 20th for the reuse endoscope.

<Processing in a case where a control signal for white balance adjustment is received>

The single-use endoscope device 10 becomes, for example, in the state in which the white balance between the image sensor 13th and the lighting element 14th and the contents of which are stored in an internal memory (with fixed white balance), delivered from the factory. Therefore, the relay adapter 40 does not adjust the white balance even if it receives a white balance adjustment control signal (a signal instructing to adjust the white balance generated by the operator's operation of the control panel) from the processor 20th for the reuse endoscope. If, on the other hand, from the relay adapter 40 If no answer is given, although a control signal for the white balance adjustment has been sent, the processor sends 20th for the reuse endoscope, this control signal continues to be sent to the relay adapter for the white balance setting 40 , and an unnecessary operation will occur. The present processing is used to avoid performing such an unnecessary process.

8th Fig. 13 is a flowchart showing the processing in the case where the relay adapter 40 the control signal for the white balance adjustment from the processor 20th for the reuse endoscope.

Step 801

The control part 41 judged on the basis of what is received from the processor 20th for the reuse endoscope received signal whether the control signal for the white balance adjustment is received. When the white balance adjustment control signal is received (when YES in step 801), the processing proceeds to step 802. When the control signal for the white balance adjustment is not in the signal from the processor 20th for the Reuse endoscope is included (if NO in step 801), the control part sets 41 surveillance continued.

(ii) step 802

The control part 41 sends a signal of a set white balance (the white balance OK signal) to the processor 20th for the reuse endoscope, which indicates that the white balance has been set, although the white balance of the image sensor 13th and the lighting element 14th in fact it was not set. In this way, it can be avoided that there is an unnecessary operation in which the processor 20th for the reuse endoscope, the control signal for the white balance setting continues to be sent to the relay adapter 40 sends.

<Additional explanation and modified example>

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

In contrast, in the present embodiment, the processor 20th The control part controls the light source provided for the reuse endoscope is not used 41 (or the lighting I / F circuit 42 ) of the relay adapter (pulse control or linear control) the lighting element (LED) 14th that is attached to the tip part 101 of the single-use endoscope device 10 is provided, and when the observation object is judged to be close, the illumination is darkened, and when the observation object is judged to be far away, the illumination is brightened. This ensures that the brightness of the recorded image is constant. To prevent the light source in the processor 20th for the reuse endoscope is operated, gives the control part 41 hence, for example, a blind signal to the processor 20th for the reuse endoscope, which indicates that the brightness adjustment is unnecessary (without such a signal, the processing loop with respect to the light source in the processor 20th interrupted and caused the system control part 21 possibly sends unnecessary control signals to components such as motors and drivers, which can lead to abnormal operation), so that the lighting control in the processor 20th not working. The control part 41 also checks the light intensity of the video signal from the imaging I / F circuit 43 , controls the lighting I / F circuit based on the light intensity as required 42 and controls (light intensity setting) of the lighting element (LED) 14th of the single-use endoscope device 10 by.

(ii) In the embodiment described above, for example, the serial number (identification information) of the single-use endoscope apparatus becomes 10 to the server 50 sent, and the server 50 manages that the endoscope device has been used, thereby preventing it from being reused. Instead of or in addition to this, the single-use endoscope device 10 however, structurally (mechanically) must be designed in such a way that it cannot be reused. In order to realize this, for example. The single-use endoscope device 10 with the relay adapter 40 or the processor for the single-use endoscope is connected, the plug part 106 is designed in such a way that when disconnected only the plug part 106 of the single-use endoscope device 10 provided connector pins (not shown) broken (destroyed so that they cannot be reconnected: neither the connecting part of the relay adapter 40 another dedicated processor will be affected).

(iii) In the present embodiment, when connecting the disposable endoscope device 10 with the relay adapter 40 its serial number (identification information) to the server 50 sent and managed. The serial number (identification information) can, however, also be sent to the server 50 sent when the single-use endoscope device 10 for a predetermined period of time with the relay adapter 40 (e.g. the length of time required to insert the device into the patient's body (a predetermined length of time)). When the single-use endoscope device 10 from the relay adapter before a predetermined period of time has elapsed 40 removed, it can be reconnected to the relay adapter 40 made available for use again instead of being immediately managed as already used. If a single-use endoscope device 10 from the relay adapter within a short time 40 is pulled out, it is considered to be pulled out before it is inserted into the patient's body. This is because it is a waste of material and resources to assume that the endoscope is consistently considered to be already in use even in such a case.

(iv) The relay adapter 40 can be formed, for example, by accommodating each component in a box-shaped housing. In this case, as in 5 shown a structure with the first connector part 46 and the second connector part 47 as a relay adapter 40 can be adopted, but the middle part of one or both connector parts can be a connecting cable structure.

The possibility of an operator (e.g. a doctor) using during the examination the relay adapter to an endoscope 40 touched, cannot be ruled out. Therefore, the first connector part 46 , the second connector part 47 and the case can be provided with a waterproof structure.

(v) The single-use endoscope device 10 can also be used without a lighting element (light source) 14th be formed. In this case, the light emitted from the light source (not shown) is generated in the processor 20th is provided for the reuse endoscope, radiated onto the observation object. To do this, the relay adapter 40 as an additional component include an LCB (Light Cable Bundle) and a structure that connects it to the single-use endoscope device 10 and the processor 20th for the reuse endoscope connects (e.g. the first connector part 46 and the second connector 47 of the relay adapter 40 are each provided with a connection point of the LCB). In this case, the light comes from the light source in the processor 20th via the LCB of the relay adapter 40 to the single-use endoscope device 10 directed. Because in this way the light source on the part of the processor 20th is used, it is not necessary to send the above-mentioned dummy or OK signals from the relay adapter 40 to the processor 20th to spend. When the relay adapter 40 formed in this way, the light source in the processor 20th can be used unchanged for the reuse endoscope.

<Summary of Embodiment>

1. (i) In this embodiment, the control part receives 41 of the relay adapter, the first specification information (information on the video signal format information that the endoscope device 10 used, or the signal level corresponding to the operation button), including the content of the signal processing in the endoscope device (e.g. single-use endoscope device) and the second specification information (information about the video signal format information sent by the processor 20th can be recognized, the signal level corresponding to the control button) including the content of the signal processing in the processor. The control part 41 compares the first specification information with the second specification information, converts the signals received from the endoscope device (video signals and key actuation signals) based on the results of the comparison, so that the processor (e.g. the processor for a conventional reuse 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 in the endoscope device 10 and in the processor 20th to ensure. Therefore the processor will be able to receive the signals, data and information from the endoscope device 10 to process.
2. (ii) The relay adapter 40 further comprises an illumination I / F part which is provided in the endoscope device and outputs a control signal to a lighting element functioning as a light source, as well as an imaging I / F part which is provided in the endoscope device and outputs a control signal to an image sensor, that takes an image of an observation object. The control part 31 gives a dummy signal to the processor 20th off, which indicates that the brightness setting is in the processor 20th contained light source is unnecessary. In this way, an error in the light source control operation in the processor can be prevented 20th caused.
3. (iii) If the control part 41 a white balance adjustment control signal from the processor 41 that the white balance setting of at least one of the in the endoscope 10 included image sensor 13th or lighting element 14th (since the white balance value is fixed on delivery), a signal for the set white balance (OK signal) is also sent to the processor 20th will be output indicating that the white balance was adjusted without performing the white balance adjustment. In this way it is possible to operate the processor 20th to guarantee. In other words, it becomes possible to avoid unnecessary operation of the processor from occurring 20th continue to send the control signal for the white balance setting to the relay adapter 40 sends.
4. (iv) The relay adapter 40 is equipped with an input part (e.g. a control button, a joystick, a touch screen, etc.) for entering instructions for controlling the functions of the endoscope device 10 Mistake. The control part 41 activates and controls one for the endoscope device 10 specific function in response to the instructions entered by the input part. It cannot, for example, from the processor 20th , but from the relay adapter 40 can be controlled as a processing for activating the function with which only the central part of the image sensor 13th recorded image is used.
5. (v) The relay adapter 40 is also with a communication part 45 provided that communicates with an external server 50 over the network 60 enables. When the single-use endoscope device 10 with the first connector part 46 of the relay adapter 40 is connected, the communication part sends 45 at least the identification information (from the control part 41 is obtained) of the single-use endoscope device 10 to the server 50 . So that can be done to the Relay adapter 40 connected single-use endoscope device 10 centrally managed as already used. The relay adapter 40 receives from the server 50 via the communication part 45 also endoscope management information indicating whether the identification information of the single-use endoscope device to be used 10 is registered with the server as already in use or not. The control part 41 then determines whether to use the single-use endoscope device based on the endoscope management information 10 , the one with the first connector part 46 connected, should be allowed. This reduces the risk of reusing the disposable endoscope device that has already been used 10 avoided.
