Description

  The present invention relates to an endoscope system that controls a plurality of medical devices.

  Conventionally, in endoscopic surgery, an operator records an intraoperative image on a recording device (hereinafter referred to as a VTR), and after the operation, confirms what kind of treatment has been performed based on the movement of the treatment instrument and the state of the tissue. .

  In addition, in the endoscope system, the setting and output frequency of the electric knife, the air supply volume of the pneumoperitoneum, and the changes in the patient's abdominal pressure parameters can be saved, and it is confirmed whether the operation has been performed reliably. I was able to.

  Both are effective as evidence that an operation has been performed, but it is difficult to understand how the operation was performed by using only a VTR or a change in parameters.

  If both can be related, the history of surgery can be faithfully reproduced.

Therefore, for example, in Japanese Patent Laid-Open No. 2003-76786 and Japanese Patent Laid-Open No. 2003-70748, an endoscope image is captured as digital data by a PC, distributed together with medical information by network transmission, and on the destination PC. Technologies that try to display each simultaneously are proposed.

  2. Description of the Related Art Conventionally, techniques using network transmission generally include communication methods such as TCP / IP, UDP (User Datagram Protocol), and RTP (Real-time Transport Protocol).

  However, these communication protocols are for P2P (Peer to Peer) or 1-to-N transmission, and in real time from a plurality of medical devices having different communication protocols such as the above-described endoscope system. When trying to acquire parameters (N-to-one transmission), there is a difference between changes in patient or device parameters and changes in images.

  The reason is that the endoscopic image generation device is different from the abdominal pressure and blood pressure, and the device that generates the output parameters of the treatment machine. This is because, since there is a delay time, the operation of the endoscopic image does not match the change in the device parameter, so that accurate information display cannot be performed.

  Since there are devices that acquire parameters by communication during surgery, even if there is a slight delay, it is possible to check by checking warnings and parameter changes on the device side. It becomes unnatural because the information on the side cannot be seen.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an endoscope system that can accurately store / reproduce medical information and faithfully reproduce the contents of treatment performed during surgery. It is said.

Time information correction means for correcting the first time information held by the plurality of peripheral devices based on the second time information, time information acquisition means for managing time information acquisition means, time information management means for managing second time information Means.

  According to the present invention, there is an effect that accurate medical information can be stored / reproduced and the contents of treatment performed during the operation can be faithfully reproduced.

  As shown in FIG. 4, the medical information multi-reproduction area 58 stores time-corrected vital sign data acquired from, for example, the patient monitor system 4 and operation setting values / measurement values of each medical device. The time change can be displayed as a waveform, and the acquired voice data can be displayed as text.

  In the medical information multi-reproduction area 58, the cursor 150 is designated by a pointing device such as a mouse or a touch panel (not shown) so that related images and parameters are linked and stored in the storage unit 50. In the endoscope image moving image / still image reproduction area 57 and the parameter numerical value display area 59, the associated images and parameters can be reproduced / displayed.

  The parameter numerical value display area 59 displays / updates the latest information (stored in the parameter acquisition unit 51) including operation information acquired by the system controller 22 through communication with each device in real time.

  FIG. 5 shows the horizontal axis as a time flow, and explains the time of each operation occurrence timing. The image data in FIG. 5 is an endoscopic moving image at the timing when the operator outputs the electric scalpel, and the image data displays information that the output electric scalpel is incising the tissue. Will be. The timing at this time is time information A63 acquired by the RTC of each device.

  Next, the time when the system controller 22 acquires the parameter that the incision output has been performed via communication is set as the timing of acquiring the electric knife output change, and the time information C65 acquired by the RTC of the system controller 22 is used. Between the time information A63 and the time information C65, a delay time (deviation) due to communication and a deviation B64 of RTC time information for each device are included.

  That is, by correcting these two deviations, real-time information synchronized with the image data can be obtained.

  First, preparation for endoscopic surgery is performed. In advance, the nurse carries the patient 48 to the bed 10 and an anesthesia operator performs anesthesia. The surgeon confirms the patient chart and procedure. The nurse performs patient assistance, anesthesia assistance, equipment installation, preparation of use tools (not shown), an endoscope, an air supply tube, etc., and prepares as shown in the endoscope system diagram of FIG. The system controller 22, each device, and the patient monitor system 4 are also activated.

  Then, as shown in FIG. 6, in step S <b> 1, communication is established between devices that can communicate with the system controller 22, time information of each device is acquired, and a difference from the time information in the system controller 22 is obtained. calculate.

  In step S2, a difference in time information for each device (hereinafter, RTC deviation time B64 for calculating a correction value) is acquired, and in step S3, parameters of each device are acquired.

  If the parameter is updated in step S4, the numerical value displayed on the display device 26 is updated in step S5, and the parameter is sequentially stored in the storage unit 50 in step S6.

  If the communication is finished in step S7, the communication operation is finished in step S8. Otherwise, the communication is sequentially performed with each device.

  Next, an explanation will be given of the operation of the saving process (the subroutine of the saving process in step S6 in FIG. 6) that sequentially saves with reference to FIG.

  As shown in FIG. 7, the time information A63 (see the parameter structure / packet structure in FIG. 9 described later) acquired by the RTC of each device in step S11 is acquired, and the system is initialized in step S12 (step S1 in FIG. 6). The RTC deviation time B64 for calculating the correction value acquired in advance and the time information C65 acquired by the RTC of the system controller 22 when the latest time information of each device is acquired are acquired.

  However, the time information A63 acquired by the RTC of each device associates the time information at the timing when the parameter update occurs for each device.

  When it is assumed that there is a deviation in the time information in step S13 (here, “displacement” means that the time required for communication is updated in real time if a certain time t is secured, and there is no “displacement”. When a communication time exceeding the time t occurs, it is recognized that there is a “deviation”).

For example,
Deviation time (occurrence) = communication time (time information C-time information A-time information B)> t
It becomes.

  If it can be recognized that a deviation has occurred, real-time information of the time information acquired at each timing is calculated in step S14.

For example, correction value B56 at the time of acquiring each parameter = (RTC deviation B + communication deviation)
Real time information A55 = time information C + correction value B (time information C−time information A may be used)
It becomes.

  In step S15, the correction value and time information for each parameter and the acquired parameter are stored.

  Next, in the reproduction process, reproduction is performed in synchronization based on the real-time information of the image data, the real-time information of the audio data, and the real-time information of the parameters of each device stored as shown in FIG.

  In this embodiment, since the audio data and image data are input directly rather than via communication, the delay time required for communication is not corrected. The correction process can be performed in the same manner as the parameters of each device.

  As described above, in this embodiment, medical procedure information such as endoscopic images, surgical device information, and patient information generated at different input devices and at different timings is accumulated in the system controller 22, and the system controller 22 is input. Since the time information of the information can be corrected, stored, or displayed, an effect that the reliability of the medical treatment information history is improved can be obtained.

  8 to 10 relate to the second embodiment of the present invention, FIG. 8 is a block diagram showing the configuration of the endoscopic surgery system, and FIG. 9 shows the data structure of communication data in the endoscopic surgery system of FIG. FIG. 10 and FIG. 10 are flowcharts for explaining the operation of the second system controller of FIG.

  In the second embodiment, only differences from the first embodiment will be described, and the same components are denoted by the same reference numerals and the description thereof will be omitted.

  In FIG. 8, the system controller 22 described in FIG. 2 of the first embodiment communicates with the second system controller 101 in the hospital / outside the hospital or the general-purpose PC 101a through the network communication 100 to transmit parameters to the remote location or from a remote location. 1 shows a system capable of communicating the operation / support information. In the present embodiment, it is assumed that there is no time information in the information obtainable from various I / Fs, and the time information can be given to each device by the RTC in the system controller 22. . Needless to say, the assigned time information can be stored in the storage unit 50 and reproduced.

  Furthermore, in the present embodiment, as shown in FIG. 8, the system controller 22 and each of the devices 13 to 16 transmit and receive medical information by RS-232C serial communication, and the system controller 22 and the patient monitor system 4 And send and receive medical information through network communication using Ethernet (R).

  Similarly to the first embodiment, the system controller 22 inputs the audio information from the microphone 33 in an analog / digital manner by voice communication, and also inputs the analog / digital input of the image information from the endoscope camera device 23 by image communication. Individual ID information from the RFID terminal 35 is input by wireless communication.

  Hereinafter, serial communication of RS-232C, network communication using Ethernet (R), voice communication, image communication, and wireless communication are referred to as in-hospital communication 102.

  FIG. 8 shows an endoscopic surgery system including a system controller 22 and an out-of-hospital system controller 101 capable of network communication 100 using a protocol such as TCP / IP or UDP, or a general-purpose PC 101a.

  Here, the in-hospital communication 102 indicates the exchange of the directly input image / sound data described in the first embodiment and the parameters and vital sign data of each device acquired by communication (the structure of the communication data is shown in FIG. (See 9 in-hospital communications).

  The network communication 100 uses the network protocol (the above-mentioned TCP / IP and UDP shown in FIG. In network communication), information is transmitted to one device or a plurality of devices (second system controller 101 or general-purpose PC 101a).

  FIG. 9 shows a conceptual diagram of a data structure when acquiring medical information between the system controller 22 and each device in the in-hospital communication 102 and the network communication 100 of FIG. 8, and in particular, packetizing the network communication 100. Thus, the image, sound, ID, and device information can be distributed based on the time information given by the network communication 100.

  FIG. 10 shows an operation flow of a control unit (not shown) in the second system controller 101 shown in FIG.

  As described in the first embodiment, when parameter communication is performed, time information of the system controller 22 is newly added, and a difference between each system and each device is acquired as a reference value when the system is initialized.

  The system controller 22 acquires medical information in a form like the in-hospital communication 102 of FIG. At this time, if data exchange occurs between the system controller 22 and each device, the time information acquired by each device (time information for each device when a parameter change occurs) is added. deep.

  For example, when performing communication using a protocol such as RTP, the system controller 22 describes time information (hereinafter referred to as a time stamp) at the timing of transmission from the system controller 22 to the second system controller 101 as packet header information. And packet data is transmitted.

  Then, the second system controller 101 receives a packet in step S21 of FIG. 10, decodes the received packet in step S22, and acquires a time stamp in step S23.

  Here, reproduction is possible on a second display device (not shown) if the receiving device is the second system controller 101, or on a liquid crystal monitor on the PC if it is the PC 101a.

  Therefore, in step S24, it is determined whether or not to perform real-time reproduction. In step S25, reproduction is sequentially performed based on the time stamp information.

  Therefore, the time stamp serves as an index indicating that the order in which the packet data of the image / sound / device parameters received by the network communication 100 is different from the order of transmission.

  If the data is not saved in step S24 but saved as data, the time stamp given to the header in step S25, the time information acquired in each device, the reference value of the correction value, and the system Based on the time information of the controller 22, the real time information is calculated as described in the first embodiment, and the storage process is performed.

  By doing so, the time lag in the in-hospital communication 102 and the time lag in network communication occurring in the network communication 100 in FIG. 8 can be corrected.

  Here, when there are a plurality of devices on the reception side of the network communication 100, the time information shift in the network communication 100 of FIG. 8 is further increased, but by performing correction processing for each device on the reception side, Storage / playback processing without deviation can be performed.

  As described above, in this embodiment, in addition to the effects of the first embodiment, even when medical information is distributed by network communication, it is possible to perform data distribution by giving time information that can be corrected on the receiver side. A highly reliable medical information history can be kept for each receiving apparatus.

  FIG. 11 is a diagram showing an example of a display layout when reproduced on the display device according to the third embodiment of the present invention or a liquid crystal monitor on a PC.

  In the third embodiment, only points different from the first or second embodiment will be described, and the same components are denoted by the same reference numerals and description thereof will be omitted.

  FIG. 11 shows a second layout example when reproduction is performed on the liquid crystal monitor on the display device 26 or the PC 101a described in the first or second embodiment, and the third embodiment takes a large reproduction area of the endoscopic image. Therefore, this is an embodiment in which medical information is displayed by superimposing processing.

  Here, the abdominal pressure of the pneumoperitoneum 14, the blood pressure obtainable from the patient monitor system 4, and the text data obtained by the voice data input are superimposed as a doctor's comment.

  In general, superimpose is to display parameter information in an analog manner by overwriting the image data. However, as in the first embodiment, image data / audio data / equipment parameter data are respectively stored. The configuration is such that superimpose ON / OFF and superimposition data selection (setting value / measurement value / error information, etc.) can be performed with the operation panel 21 or the like as selection means.

  In this embodiment, during the operation, the surgeon wants to concentrate on viewing the endoscopic image, so the superimpose processing is turned off, for example, only when an error occurs in each device. .

  At this time, the image data / audio data / parameters of each device are stored together with the real-time information as in the storage unit 50 of FIG.

  Therefore, after the operation is completed, the stored information can be reproduced by reproducing only the endoscopic image, while performing superimposition, or in a state where the superimposition of error information is turned off.

  As described above, in this embodiment, in addition to the effects of Embodiments 1 and 2, an important endoscopic image is not reduced during the operation, and missing due to parameter superimposition does not occur. It is possible to perform reproduction after associating each device parameter so that there is no time lag.

  FIG. 12 is a configuration diagram showing the configuration of the endoscopic surgery system according to the fourth embodiment of the present invention.

  In the fourth embodiment, only differences from the second embodiment will be described. The same components are denoted by the same reference numerals, and description thereof will be omitted.

  Unlike the second embodiment, this embodiment may transmit time information based on the RTC in the system controller 22 when there is time information in the information that can be acquired from the in-hospital communication 102 (either serial or network). FIG. 12 shows a system configuration in which the time information of the system controller 22 is sent to the peripheral devices 4 and 13 to 16 and data is exchanged based on the RTC information of the system controller 22. .

  In this embodiment, when the endoscopic surgery system 3 is activated and communication is established with each peripheral device, time information from the system controller 22 is transmitted to each peripheral device. At this time, each peripheral device can communicate the parameter change based on the time information sent from the system controller 22 when the parameter change occurs. Further, since the system controller 22 or the PC 101a can recognize and save the parameter time information acquired by communication as in the first embodiment, it can be reproduced regardless of the RTC shift between the peripheral devices and the shift due to communication.

  As described above, in this embodiment, in addition to the effects of the second embodiment, by distributing to the communication partner using the time information of the system controller 22, the parameter change of each peripheral device and the deviation of the data of the endoscope image can be easily performed. It can be eliminated.

  FIGS. 13 and 14 relate to Embodiment 5 of the present invention, FIG. 13 is a block diagram showing the configuration of the endoscopic surgery system, and FIG. 14 is a block diagram showing a configuration example of the local network of FIG.

  In the fifth embodiment, only differences from the fourth embodiment will be described. The same components are denoted by the same reference numerals, and the description thereof will be omitted.

  In this embodiment, as shown in FIG. 13, the devices 4 and 13 to 16 capable of communicating with the first communication I / F 40 as in the fourth embodiment have RTCs and are capable of Ethernet (R) communication. In this embodiment, the system controller 22 acquires reference time information from an NTP (Network Time Protocol) server 503 via the global network 502 connected to the PC 101a when the network 501 is provided.

  Note that the global network 502 is a network having a global address, and an IP address is distributed from, for example, a DHCP server.

  As for the realization configuration of the local network 500, a serial / Ethernet (R) communication adapter 510 and a switching hub 511 as shown in FIG. 14 may be used.

  As a means for realizing the serial / Ethernet (R) communication adapter 510, for example, a Lantronix XPort device can realize a connection function to a network economically and in a short period of time. The Lantronix XPort device is a small package of about 14.5 mm x 34 mm x 18.25 mm, and all functions of the CPU, memory, and protocol are contained in the RJ45 Ethernet (R) connector.

  At this time, in this embodiment, it is necessary to assign an IP address for a local address to each device. The system controller 22 acquires data from the devices 4 and 13 to 16 via the switching hub 511 based on the IP address.

  Of course, if the NTP protocol is used, time information is given to the communication data bucket. Among the devices that can be connected to the network, the PC 101a that can be connected to the global network 502 can adjust the time information held internally based on the time information from the NTP server 503 or the like.

  Therefore, the system controller 22 acquires time information adjusted from the PC 101a, and stores time information in devices such as the endoscopic camera device 15, the light source device 16, the pneumoperitoneum device 14, and the electric scalpel device 13 capable of local network communication. Can be delivered and adjusted.

  For the audio information from the microphone 22 without time information, the image information from the endoscope camera device 15, and the individual ID information from the RFID terminal 35, the system controller 22 gives time information at the time when the information is acquired. And can be saved / reproduced.

  In addition, since NTP can periodically adjust time information at a certain period, it does not always shift.

  Of course, in the case of a device incapable of network communication with the system controller 22 having the first communication I / F 40, the system controller 22 also includes information on each device as well as analog input information such as voice / image. Needless to say, the same effect as in the present embodiment can be obtained if time information acquired by NTP is given and stored and reproduced.

  The present invention is not limited to the above-described embodiments, and various changes and modifications can be made without departing from the scope of the present invention.
