  The medical image recording device 12 acquires an image (moving image), biological information, and operation information from each unit to be described later, and records the acquired information. Further, the medical image recording device 12 generates and reproduces an image based on the acquired information. The medical image recording apparatus 12 will be described in detail later.

  The display 14 is a device that displays an image such as a liquid crystal display, and displays an image produced by the medical image recording device 12.

  The endoscope unit 16 is a device that is inserted into a patient to be operated and acquires an in-vivo image. The endoscope unit 16 is inserted into a patient and includes an insertion portion 16a provided with an imaging mechanism at the tip, an operation portion 16b operated by an operator (such as a surgeon, that is, a doctor), and an imaging mechanism of the insertion portion 16a. The processing unit 16c processes the acquired image information and generates an image. In addition to the fiberscope type endoscope in which the insertion portion is formed of a soft material, the endoscope of the endoscope unit 16 includes a cystoscope, thoracoscope, abdominal cavity, in which the insertion portion is formed of a hard material. A mirror or the like can be used. Further, the endoscope unit 16 sends the acquired image information to the medical image recording apparatus 12. Note that the endoscope unit 16 and the medical image recording apparatus 12 are electrically insulated and transmit and receive information by optical communication using, for example, an optical coupler.

  The biological monitor 18 measures or detects biological data of the patient and displays it on the display. Here, examples of the biological data measured or detected by the biological monitor 18 include a pulse, a heart rate, a blood pressure, a body temperature, an electroencephalogram, a blood oxygen concentration, and a blood carbon dioxide concentration. In addition, the biological monitor 18 sends the acquired biological data to the medical image recording device 12, similarly to the endoscope unit 16. The biological monitor 18 and the medical image recording apparatus 12 are also electrically insulated, and information is transmitted / received by optical communication using an optical coupler, for example.

  The operating room imaging unit 20 is a camera that images an operating room in which surgery is performed. The operating room photographing unit 20 can photograph a person in the operating room, an operating table, and various devices. Note that the operating room imaging unit 20 may be a fixed type, may be configured to capture an image of the same region, or may be movable, and the imaging region may be changeable. Similarly to the endoscope unit 16, the operating room imaging unit 20 also sends acquired image information to the medical image recording device 12.

  The surgical tool (surgical instrument) 22 is an instrument used for surgery such as an electric knife and an ultrasonic knife. In FIG. 1, two surgical tools 22 are shown, but the number of surgical tools is not limited. The output unit 24 is connected to the surgical tool 22 and drives the surgical tool 22 based on the operation of the operator. That is, the output unit 24 supplies power to the surgical instrument 22 such as an electric knife or an ultrasonic knife to drive it. The surgical tool 22 is supplied with electric power from the output unit 24 and is driven to cut the patient's tissue or burn the patient's tissue.

  The operation detection unit 26 is disposed in a cord portion that connects the surgical tool 22 and the output unit 24, detects current flowing between the surgical tool 22 and the output unit 24, and is the surgical tool 22 used? Detect whether or not. As the operation detection unit 26, for example, a clamp meter (overhead ammeter) that can detect whether a current flows only by sandwiching a cord through which the current flows can be used. The clamp meter detects the current flow by detecting the magnetic field generated around the cord when the current flows. The operation detection unit 26 sends the detected value to the medical image recording apparatus 12. The medical image recording apparatus 12 determines whether the surgical tool 22 has been used based on the detection value sent from the operation detection unit 26. The operation detection unit 26 may detect whether the surgical tool 22 has been used from the detected value, and send the detection result to the medical image recording apparatus 12.

  The input unit 28 is an input terminal through which an operator inputs instructions to the medical image recording device 12. The input unit 28 sends an instruction input by the operator to the medical image recording apparatus 12. Here, as the input unit 28, a keyboard, a mouse, a foot switch, a touch panel, or the like can be used. By using a touch panel as the input unit 28, the operator can easily perform an operation. The touch panel is arranged on the surface of the display and detects an input instruction based on the relationship between the screen displayed on the display and the contact position by the operator. The medical system 10 is configured as described above.

  Next, the medical image recording apparatus 12 will be described with reference to FIG. FIG. 2 is a block diagram showing a schematic configuration of the medical image recording apparatus shown in FIG. As described above, the medical image recording device 12 is a device that records and reproduces images and data supplied from each unit, and includes a moving image acquisition unit 40, an information acquisition unit 42, a synchronization unit 44, and feature point detection. Unit 46, input detection unit 48, display control unit 50, storage unit 52, transmission / reception unit 54, and control unit 56.

  The moving image acquisition unit 40 acquires image data from each unit of the medical system 10. Specifically, the image data sent from the endoscope unit 16 and the image data sent from the operating room imaging unit 20 are acquired. That is, the moving image acquisition unit 40 acquires the image data acquired by the endoscope unit 16 from the endoscope unit 16 and acquires the image data acquired by the operating room imaging unit 20 from the operating room imaging unit 20.

  The information acquisition unit 42 acquires information acquired by each unit of the medical system 10. Specifically, the information acquisition unit 42 acquires biological data sent from the biological monitor 18. That is, the information acquisition unit 42 acquires the biological data acquired by the biological monitor 18 from the biological monitor 18. Moreover, the information acquisition part 42 acquires the value detected by the operation detection part 26, and acquires the information of whether the surgical tool 22 was operated based on the acquired value.

  The synchronization unit 44 synchronizes the image data acquired by the moving image acquisition unit 40 and various data acquired by the information acquisition unit 42. That is, the synchronization unit 44 matches the time axes of each image data and various data, and associates each image data with various data. By synchronizing with the synchronization unit 44, it is possible to prevent the time axis of each data from being shifted during data reproduction. Here, the method of synchronizing each data with the synchronizing part 44 is not specifically limited, For example, what is necessary is just to add flag data to each data. Further, data for every fixed time may be packetized and stored. Data of the same time may be used as one unit.

  The feature point detection unit 46 detects a time when a certain change has occurred from the image data acquired by the moving image acquisition unit 40 and various data acquired by the information acquisition unit 42, and the time when the change has occurred is a feature point. And In the present embodiment, the use of the surgical tool 22 is set to be detected as a feature point, and the time point when the surgical tool 22 is determined to be used is detected as a feature point based on the information acquired by the information acquisition unit 42.

  The input detection unit 48 detects a signal sent from the operation detection unit 26. That is, the input detection unit 48 detects a signal input when the operator operates the operation detection unit 26.

  The display control unit 50 generates an image to be displayed on the display 14 based on the data sent from the control unit 56. The storage unit 52 stores data sent from the control unit 56. Note that a cache memory can be used as the storage unit 52. By using a cache memory as the storage unit 52, data can be read out in a short time. The storage unit 52 may be a storage unit that can store a large amount of data although it takes time to read data from a hard disk or the like. Examples of the format for recording (encoding) the acquired moving picture information include MPEG (Moving Picture Experts Group) -1, MPEG-2, MPEG-4 (mainly in the case of mobile communication, H.261 (International For example, in MPEG-2, the encoded information is composed of PES (Packetized Elementary Stream) packets (variable length), which are packets of appropriate length units. The moving image information is acquired as a stream composed of a plurality of PES packets.

  The transmission / reception unit 54 transmits / receives data to / from an external network or an external storage device. The transmission / reception unit 54 sends data generated by each unit (image data to be reproduced) and data stored in the storage unit 52 to an external network or an external storage device, and stores the data in the external device. Also, data stored in the external device is read.

  The control unit 56 controls the operation of each unit of the medical image recording apparatus 12 described above, and performs reproduction, storage, readout, and the like of the image created from the acquired image data and various data. The medical image recording device 12 is configured as described above.

  Next, operations of the medical system 10 and the medical image recording device 12 will be described. First, a method for recording (storing) acquired data will be described with reference to FIG. FIG. 3 is an explanatory diagram for explaining an example of an image and information recording method. Here, in the diagram shown in FIG. 3, “video information 1” is image data acquired by the endoscope unit 16, and “video information 2” is image data acquired by the operating room imaging unit 20. Further, “biological information” is data acquired by the biological monitor 18, and “operation information” is operation data of the surgical tool 22 acquired based on a signal from the operation detection unit 26.

  As shown in FIG. 3, the data of “video information 1”, “video information 2”, “biological information”, and “operation information” are sent from the above-described units to the medical image recording apparatus 12 and processed by each unit. By doing so, it becomes data. Moreover, by synchronizing with the synchronizer 44, it matches with the same time axis, as shown in FIG. Each data is cut out for each predetermined time section in a state of being associated with each other. Specifically, data in a certain time range is cut into three parts, a cutout part 1, a cutout part 2, and a cutout part 3. When cutting out, each cutout part also cuts out data in the same time zone as the adjacent cutout part. For example, when data starting from 0 seconds is cut out every 20 seconds, the cut out portion 1 cuts out data from 0 seconds to 20 seconds, the cut out portion 2 cuts out data from 18 seconds to 38 seconds, The cutout part 3 cuts out data from 36 seconds to 56 seconds. Thereby, when connecting the cut-out data again, since a part of image becomes the same data, it becomes easy to collate and can connect data correctly.

  The data thus extracted includes data of “video information 1”, “video information 2”, “biological information”, and “operation information” in the same time period. For example, the cutout part 1 includes “video information 1-1”, “video information 2-1”, “biological information-1”, and “operation information-1”, and an aggregate of the data is a data unit. 1 is generated. The data unit 1 may also include synchronous data, that is, time axis flags and feature point data described later. The data unit generated in this way is stored in the storage unit 52 or stored in the external storage device from the transmission / reception unit 54. Further, by reading and reproducing the data unit by the control unit 56, an image can be reproduced on the display 14. In addition, it is possible to reproduce a plurality of data units continuously over a certain time by reproducing them continuously along the time axis.

  Next, an example of an image produced by the medical image recording device 12 and displayed on the display 14 will be described with reference to FIG. FIG. 4 is a screen diagram illustrating an example of an image displayed on the display. As shown in FIG. 4, an image 104, an image 106, a graph 108, a graph 110, and operation keys 112 are displayed on the screen 102 of the display 14. The image displayed on the screen 102 is generated by the control unit 56 and the display control unit 50 based on the data, information, and instructions acquired from the moving image acquisition unit 40, the information acquisition unit 42, and the input detection unit 48.

  The image 104 is an image acquired by the endoscope unit 16 and displays an image (moving image) of the surgical field where the operator is performing processing, that is, the surgical target organ or the like. The image 106 is an image acquired by the operating room imaging unit 20 and displays images (moving images) of operators in the operating room, patients, surgical tools, and the like.

  The graph 108 and the graph 110 are biological data acquired by the biological monitor 18. On the screen 102 shown in FIG. 4, the blood pressure detection result is displayed as a graph 108, and the pulse detection result is displayed as a graph 110. Note that the images and data displayed in the image 104, the image 106, the graph 108, and the graph 110 are data at the same time synchronized by the synchronization unit 44.

  Next, the operation key 112 displays a key for operating the medical image recording apparatus 12. For example, keys for inputting instructions such as playback, stop, fast forward, rewind, recording start, and feature point movement are displayed. The operation key 112 is displayed based on the input from the input unit 28 so that the selected key can be confirmed. For example, only the selected key is displayed in a different color. In this way, by changing the display of the selected key, the operator can confirm which key is selected by the input to the input unit 28.

  In this way, the medical image recording apparatus 12 creates an image from various synchronized images and data and displays the image on the display 14. Here, the medical image recording apparatus 12 may display data currently acquired by each unit on the screen 102 in addition to the image obtained by reproducing the stored data. That is, a real-time image (image to be recorded) may be displayed. In addition, it is preferable that the screen 102 also displays a graph displaying the time of detection of the feature points with the horizontal axis as the time axis so that the operator can recognize the detection timing of the feature points.

  Next, an example of processing of the medical image recording apparatus 12 will be described with reference to FIGS. Here, FIG. 5 is a flowchart showing an example of processing by the medical image recording apparatus. FIG. 6 is an explanatory diagram showing the relationship between the feature points detected by the medical image recording apparatus and the recorded data. The process shown in FIG. 5 is an example of a recording operation.

  First, as a preparation, the operator connects the medical image recording device 12 and other parts of the medical system 10 to obtain a state where image data and various data can be acquired. Further, the medical image recording device 12 and the display 14 are connected so that an image generated by the medical image recording device 12 can be displayed on the display 14. Thereafter, the medical image recording device 12 is activated. Note that the order of preparation is not particularly limited, and each unit may be connected after the medical image recording apparatus 12 is activated.

  When the preparation is completed, the medical image recording apparatus 12 determines whether there is a recording start instruction as Step S12. Here, the recording start instruction is an instruction input when the operator operates the input unit 28. If it is determined in step S12 that there is no recording start instruction (No), the medical image recording apparatus 12 performs the determination in step S12 again. That is, the medical image recording apparatus 12 repeats the determination in step S12 until a recording start instruction is issued.

  If it is determined in step S12 that there is a recording start instruction (Yes), the medical image recording apparatus 12 starts recording in step S14. That is, the images and information acquired from each unit are synchronized and stored in the storage unit 52. Moreover, it is memorize | stored in an external storage device via the transmission / reception part 54 as needed.

  When the medical image recording apparatus 12 starts recording in step S14, the medical image recording apparatus 12 determines whether or not the surgical instrument 22 has been used in step S16. That is, it is determined whether use of the surgical tool 22 is detected based on a signal from the operation detection unit 26 during recording of images and various data. The use of the surgical tool 22 can be detected by detecting the current flowing between the surgical tool 22 and the output unit 24 by the operation detection unit 26. In other words, in the present embodiment, it is determined that the surgical instrument 22 has been used when a current is passed through the surgical instrument 22 and there is a high possibility that the target portion of the patient has been incised or hemostatic. If the medical image recording apparatus 12 determines in step S16 that the surgical tool 22 is not used (No), the medical image recording apparatus 12 proceeds to step S26.

  If the medical image recording apparatus 12 determines in step S16 that the surgical tool 22 has been used (Yes), it sets the time immediately before use as a feature point in step S18. That is, the time point immediately before the surgical instrument 22 is used and an incision is made or hemostasis is performed is set as a feature point. The setting immediately before use is not particularly limited, and may be set in any way. For example, a predetermined time (0.5 seconds before, 1 second before, 5 seconds before) that is determined to be used may be set as the immediately preceding time. The medical image recording device 12 attaches flag data to the time point set as the feature point so that it becomes the reference (reference for cueing) at the time of reproduction. Note that it suffices if the feature points can be identified, and in addition to attaching flag data, a table (table) of the correspondence between the time corresponding to the synchronized time axis and the feature points may be created.

  The medical image recording apparatus 12 determines whether there is a recording end instruction as step S26 when the feature point is set at step S18 or when it is determined No at step S16. Similar to the recording start instruction, the recording end instruction is input by the operator operating the input unit 28, and the medical image recording apparatus 12 determines whether or not this instruction is input. The recording end instruction is an instruction to end recording of images and data acquired by each unit.

  If the medical image recording apparatus 12 determines in step S26 that there is no image end instruction (No), the medical image recording apparatus 12 proceeds to step S16 and repeats the above operation. That is, the medical image recording apparatus 12 repeats the processes in steps S16 and 18 until a recording end instruction is input. If it is determined in step S26 that there is a recording end instruction (Yes), the medical image recording apparatus 12 performs a recording end process in step S28 and ends the process. The medical image recording device 12 records the image (moving image), various information, and feature points as recording data while synchronizing them as described above.

  Thereby, as shown in FIG. 6, the time (feature point data) at which the surgical tool (tool) is used is recorded in the recorded data from the start of the operation to the end of the operation. Specifically, the time when the device A is used (used), the time when the device B is used, and the time when the device C is used are recorded in the recorded data. Moreover, it is memorize | stored whether the instrument was used as feature point data, and when displaying on a display, as shown in FIG. 6, the detection factor of each feature point is matched and displayed as a comment. Note that this detection factor may not be displayed.

  Next, a method for reproducing the recorded data will be described with reference to FIG. 6 and FIGS. 7-1 to 7-3. FIGS. 7A to 7C are screen diagrams for explaining an example of processing by the medical image recording apparatus.

  As shown in FIG. 6, the medical image recording device 12 has feature point data recorded in the recording data, and is set as a base point at the time of reproduction. That is, the time point of the feature point is set as the time point of the beginning of playback. Thereby, the operator can reproduce an image using the feature point as a base point. As an example, when a skip is input during image reproduction, the operator can reproduce an image from the next feature point. When a mouse is provided as an input unit, an image from a feature point can be reproduced by clicking the feature point.

  More specifically, first, when the surgical tool 22 is used during image recording, as shown in FIG. 7A, the time point immediately before starting the incision (resection) of the target portion by the surgical tool 22 is a feature point. Set as As a result, when the operator inputs an instruction to reproduce from the feature point, the moving image is reproduced from the time point of the screen shown in FIG. 7A and the image 104a for excising the target portion is displayed. Thereafter, by continuing to reproduce the image, as shown in FIG. 7B, an image 104b in which the excision of the target portion has been completed after a predetermined time has elapsed from the time of the image 104a is displayed. At this time, other images and data of the screen 102 are also displayed as the images and data at the time of the image 104b. When the medical image recording apparatus 12 reproduces an image, the medical image recording apparatus 12 may reproduce an image for a preset time, or may reproduce an image until a stop instruction is input by an operator. Good.

  Note that the display method of images during reproduction is not limited to displaying images of the same time (synchronized), and images of different times may be displayed on one screen. For example, as shown in FIG. 7-3, the image 104a acquired by the endoscope unit 16 at the time of the feature point is displayed as a still image, and another region (the image 104b in FIG. 7-3 is displayed). You may make it display the moving image acquired by the endoscope unit 16, ie, the image acquired after the feature point, in (part). In this manner, images can be compared by displaying images in different time zones in parallel.

  As described above, the medical image recording apparatus 12 can reproduce the image based on the feature point by detecting the feature point and including the feature point data in the recording data. Thereby, it is possible to reproduce an image (moving image) in a time zone during which a process is performed without searching for a point (time) at which the operator starts reproduction. In addition, by detecting the use of surgical tools, which is an important act in surgery, and confirming images (videos) of using surgical tools, the operator can understand the problems and techniques that occurred during the surgery. be able to. That is, it is possible to easily reproduce the time when the surgical tool is used, which is highly likely to require confirmation with an image, so that the image requested by the operator can be easily reproduced.

  For example, because advanced medical technology, especially endoscopic surgery, is difficult to learn, an instructor (a highly skilled doctor) may instruct an inexperienced doctor (ie, a surgeon or operator). is there. In such a case, by using the apparatus of the present invention, it is possible for the instructor to easily view the video while performing the operation immediately before performing the operation using the surgical tool. Thereby, the instructor can grasp the immediately preceding state and processing, can grasp the problem in an effective and short time, and can instruct an inexperienced doctor. Conversely, even when an unskilled doctor views and conducts research on an operation image operated by the instructor, only the image portion operated by the instructor can be viewed. As a result, necessary images can be viewed in a short time, and surgery can be grasped in a short time. Thereby, it becomes possible to view an effective image efficiently.

  In addition, by playing the video while displaying the base image of the feature point, the viewer can analyze the problem and the processing method while comparing the situation before the treatment and the image being processed. it can. Further, by reproducing the moving image while displaying the image of the base point of the feature point, the operator can grasp the change of the processing target part (affected part). As a result, it is possible to grasp the change in the target site that occurs when the operator performs a treatment with a surgical tool (such as an electric knife or an ultrasonic knife) during the operation, and the contents of the treatment, that is, the size of the incised region. It is possible to easily confirm changes in bleeding. Thereby, it is possible to grasp the surgery more accurately.

  In addition, by automatically extracting feature points, the operator can insert a comment (which surgical tool was used) or check a tag (becomes a head) while checking the image during or after surgery. Necessary comments and tag settings can be made without entering settings. Thereby, an operator's burden can be eased. In addition, since it is possible to omit the trouble of inserting a comment, it is preferable that the medical image recording apparatus stores the factor that detected the feature point (what was detected and set as the feature point) together with the feature point. Further, by displaying the feature points and displaying the detection factors of each feature point (which surgical tool was used) as shown in FIG. 6, the flow of the surgical tools used during the operation and the use thereof are displayed. The timing can also be grasped. Thereby, it becomes easy to grasp the flow of the entire operation.

  In the above embodiment, since the data can be reproduced with a simple operation using the feature point as a base point, the case where the data is cued and reproduced from the feature point has been described, but the cued reproduction function is not necessarily required, and the medical image recording apparatus 12 can also reproduce the surgical image from the beginning. Even in this case, since the feature point data is acquired in advance, the flow of the operation can be grasped, and the data from the feature point can be reproduced by the operation of the viewer.

  In addition, as shown in FIG. 3, by storing a plurality of data as data units and storing them separately, some images and data can be reproduced even during recording. In addition, storage can be performed in parallel with reproduction. In addition, since the synchronized data on the same time axis can be taken out, the data can be easily read out. The various effects described above can be obtained by recording data units as in this embodiment, but the present invention is not limited to this, and the data recording method is not particularly limited. For example, each data may be stored separately. Alternatively, a plurality of recording devices may be prepared, and when a reproduction instruction is input, an image may be reproduced by one of the plurality of recording devices.

  Here, it is preferable that the medical image recording apparatus 12 displays the acquired image on the display even during image recording. As a result, it is possible to more accurately grasp the status of surgery and the data to be recorded. Note that an image may be displayed only when a reproduction instruction is given. Moreover, when displaying the image acquired at the time of image recording, it is preferable that the medical image recording apparatus 12 displays the image of a feature point (image acquired by the endoscope unit 16) on the display 14. Thereby, the screen detected as the feature point can be grasped at the time of recording.

  Further, as shown in FIG. 6, the medical image recording apparatus 12 may display feature points on a graph with the horizontal axis as time, but displays the feature point images as thumbnail images for playback. An image of feature points to be selected may be selected. In this way, by displaying the feature points based on the time axis and thus the reference and selecting from the images at each time point, it is possible to select a necessary image and an image to be reproduced in a short time.

  In the above-described embodiment, the image is reproduced using the feature point as a base point. However, the image may be reproduced from a time point that is a preset time before the feature point. By setting in this way, the feature point and the set time point can be confirmed as a moving image. Accordingly, even when the use of the surgical tool is detected as the feature point, the image can be reproduced before the surgical tool is used.

  In the above-described embodiment, the use of the surgical tool can be accurately and easily detected, and a surgical tool that uses electricity is often used for processing such as incision and hemostasis. Although the current flow was detected using, the method of detecting the use of the surgical tool is not limited to this. The use of the surgical tool may be detected by performing image processing on an image captured by the endoscope unit or the operating room photographing unit and detecting the movement of the surgical tool. When image analysis is used in this way, image processing is required, but the use of a surgical instrument that does not use electricity can also be detected. In addition, the surgical tool may be detected from the shape of the surgical tool, but an identification display such as a barcode or a QR (registered trademark, Quick Response) code is attached to the surgical tool, and the identification display is read. Good.

  Further, the medical image recording apparatus 12 may extract data related to the feature points from the acquired data. Hereinafter, a description will be given with reference to FIGS. Here, FIG. 8 is a flowchart illustrating an example of processing by the medical image recording apparatus, and FIG. 9 is an explanatory diagram illustrating a relationship between the recording data and the extracted recording data by the medical image recording apparatus. The medical image recording device 12 reads out the stored (saved) data when storing (storing) the data acquired from each unit, and stores only a part of the data. It may be extracted and stored.

  First, as shown in FIG. 8, the medical image recording apparatus 12 detects a feature point from data as step S102. If this data is once recorded (stored), it becomes data of feature points included in the recorded data. If it is data (information, image) acquired from each part, the data is analyzed. It is the feature point detected by this.

  When the medical image recording apparatus 12 detects the feature point in step S102, in step S104, the medical image recording apparatus 12 extracts data on the basis of the feature point. Specifically, recording data for a set time is extracted with a feature point as a starting point. Here, the set time is a preset time, for example, 30 seconds, 1 minute, 3 minutes, or the like. The medical image recording apparatus 12 extracts recording data for each feature point detected in step S102. In addition, when processing is performed while acquiring data from each unit, that is, while acquiring data of a currently performed operation, the processes of steps S102 and S104 are repeated.

  After extracting the data in step S104, the medical image recording apparatus 12 connects (combines) the extracted data based on the time axis in step S106. That is, the data extracted in step S104 is arranged in time order and combined with adjacent time data. For example, when the data is a data unit as shown in FIG. 3, a flag or the like that sets the order of reproduction along the time axis is added.

  When the medical image recording apparatus 12 concatenates the data in step S106, the medical image recording apparatus 12 stores the concatenated data in step S108. Note that the data may be stored (stored) in the storage unit 52 or may be stored in an external storage device via the transmission / reception unit 54.

  The medical image recording apparatus 12 can create data by extracting only data for a certain period of time with reference to feature points, as shown in FIG. 9, by extracting data with reference to feature points. Specifically, by extracting the data 140a, 140b, 140c, 140d based on the feature points from the recorded data shown in the upper part of FIG. 9, and connecting them as shown in the lower part of FIG. Can be created. Note that the data 140d is extracted as one data section because the time interval from the feature point to the feature point is short.

  Thereby, in this embodiment, the data of the time slot | zone when the surgical tool is not used can be removed, and the data which extracted only the data of the time slot | zone using the surgical tool can be created. That is, it is possible to create a digest version of data that extracts a time zone that the viewer is likely to view. Moreover, the data which becomes this digest version can be created automatically. Also, by creating digest version data in this way, the viewer can view only feature point data (video, biometric data) without performing an operation such as skipping, and in a short time, , You can watch valid materials with a simple operation.

  Note that extraction conditions based on feature points can be set in various settings. For example, when the time interval between feature points is equal to or less than a certain value, the continuous processing is performed between feature points. These data may be extracted without being divided.

  Moreover, in the said embodiment, although use of the surgical tool was detected as a feature point, this invention is not limited to this. Biometric data (biological information) can also be used as the feature point. Hereinafter, the case where biometric data is used as a feature point will be described with reference to FIG. Here, FIG. 10 is a flowchart showing another example of processing by the medical image recording apparatus. The process shown in FIG. 10 is the same as the process shown in FIG. 5 except for the feature point detection process. Will be omitted, and the points peculiar to the processing of FIG. 10 will be mainly described below.

  First, preparation similar to the above processing is performed. When the preparation is completed, the medical image recording apparatus 12 determines whether there is a recording start instruction as Step S12. If it is determined in step S12 that there is no recording start instruction (No), the medical image recording apparatus 12 performs the determination in step S12 again. If it is determined in step S12 that there is a recording start instruction (Yes), the medical image recording apparatus 12 starts recording in step S14.

  When the medical image recording apparatus 12 starts recording in step S14, it determines in step S40 whether there is an abnormality in the biometric data. Here, as described above, the biological data includes a pulse, a heart rate, a blood pressure, a body temperature, an electroencephalogram, a blood oxygen concentration, a blood carbon dioxide concentration, and the like. Whether or not there is an abnormality in the biometric data is determined by whether or not the numerical value (detection value) of the biometric data is within a predetermined range. The determination of whether or not there is an abnormality may be determined to be abnormal if it is out of the predetermined range even for a moment, but the numerical value of the biological data is greater than or equal to the set time or the set number of times If it is out of the predetermined range, it may be determined that the biometric data is abnormal. If the medical image recording apparatus 12 determines in step S40 that the biometric data is not abnormal (No), the medical image recording apparatus 12 proceeds to step S26.

  If the medical image recording device 12 determines that the biometric data is abnormal (Yes) in step S40, the medical image recording device 12 sets, as step S42, the time point immediately before the determination as abnormal is a feature point. That is, the time point immediately before the biometric data falls outside the predetermined range is set as the feature point. In the present embodiment, the immediately preceding setting is not particularly limited and may be set in any manner. For example, a predetermined time (0.5 seconds before, 1 second before, 5 seconds before) when the biometric data is determined to be abnormal may be set as immediately before. In addition, when it is determined that the biometric data is abnormal when the numerical value of the biometric data is out of the predetermined range for the set time or more than the set number of times, the first time when the biometric data is out of the predetermined range May be used as the feature point immediately before the time when it first deviates from the predetermined range. If the medical image recording apparatus 12 determines that the previous time point is a feature point in step 42, the medical image recording apparatus 12 proceeds to step S26. Note that the processing after step S26 is the same as the processing of the flowchart shown in FIG.

  As described above, by detecting the feature points based on the biometric data, it is possible to reproduce an image from the time when the change of the patient occurs. Thereby, when a problem occurs, the cause of the problem can be grasped in a shorter time. In addition, various effects similar to those described above can be obtained.

  Further, bleeding may be detected as a feature point. Hereinafter, a method for detecting a bleeding point by the medical image recording apparatus 12 will be described.

The control unit 56 of the medical image recording device 12 detects a motion region (region with motion) having a predetermined feature to be detected from the moving image information image acquired by the endoscope unit 16, and this motion region The state of the motion region is determined based on the amount of change. Here, the “motion region” is a region where the area changes in a series of moving images or a region where there is motion (that is, movement). Specifically, a surgical instrument for use in surgery, organ, and hemorrhage in the affected area. In the present embodiment, the bleeding area in the affected area is specified from the plurality of movement areas, and the state of the bleeding area, specifically, the change in the area of the bleeding area and the amount of bleeding are grasped. Hereinafter, a method for detecting bleeding will be described in detail.

  First, the control unit 56 of the medical image recording apparatus 12 has two images, that is, an image at a certain point in time and an image before a predetermined time (preset time) as images of moving image information acquired by the endoscope unit 16. Images are acquired, the acquired images are compared, and the degree of coincidence of the images is determined. That is, it is determined to what extent the area (common area) in which the same part of the patient is imaged is determined between an image at a certain time point and an image before a predetermined time. If the degree of coincidence of images is equal to or greater than a certain level (for example, 80% or more of the two images coincide), it is determined that the same part of the patient is being photographed, and motion determination is performed. If the degree of coincidence of images is less than a certain level, it is determined that the shooting scene has been switched, and no motion determination is performed. Note that the degree of coincidence of images is the area that can be detected as the corresponding part by detecting the corresponding part of both images by extracting the contour, color, etc. of the subject by image processing and comparing the whole images Calculate from percentage

  Next, the control unit 56 detects all the motion areas having a predetermined size or more from the moving image information image acquired by the endoscope unit 16 and calculates the amount of change in these motion areas. Here, the “change amount of the motion region” is the change amount or change rate (change speed) of the area of the motion region. The change amount of the area of the motion region is the difference between the area of the region at a certain time t and the area of the region at a time t + Δt after a minute time. The change rate of the area of the motion region is the time difference Δt. Calculated by dividing. In the following description, for convenience, the number of images to be compared for explaining the case where the amount of change in area is calculated from images at two times is not limited. In addition, by increasing the number of images to be compared, for example, using images at three or more times and using a statistical average to determine the amount of change in the motion region, the detection accuracy of the amount of change in the motion region is further improved. Can be made.

  First, each area (size) of the subject shown in the image is detected. For example, for each of two images, an image at a certain point in time and an image before a predetermined time, the image is decomposed into a plurality of pixels, the chromaticity of each pixel is obtained, and a portion composed of pixels having similar chromaticity is obtained. Detect as a region. The region detection method is not limited to this, and the contour of the subject may be detected by image processing, and the region to be drawn may be detected from the contour. As described above, when the subject area of each image is detected, the area of the image at a certain point in time is compared with the area of the image before a predetermined time. As a result of the comparison, a region where the position of the region (relative position in the image) has moved or the size of the region has changed is detected as a motion region.

  Next, the control unit 56 removes, as a noise component, a motion region that is not related to the bleeding point (bleeding region) from the detected plurality of motion regions. Here, examples of the noise component include a movement of a surgical tool used during a surgery, a movement of an organ, and the like. The noise removal processing method is not similar to the preset blood chromaticity, the area of the area does not increase with the passage of time, the area does not continue to increase for a certain period of time, for all detected motion areas. It is determined whether or not the three conditions are met. Then, the motion region corresponding to any one of these three conditions is determined as noise, and is deleted (excluded) from the detected motion region. As a result, when all of the above three conditions are not met, that is, the area of the region increases with the passage of time, and the area continues to increase for a certain period of time, and the blood chromaticity set in advance is Only the motion region that satisfies the condition of similarity is extracted, and the extracted motion region is detected as a “bleeding point”.

  When removing the surgical tool region by noise removal, the shape data of the surgical tool used in the surgery is stored in the storage unit 52 in advance, and the shape of the motion region detected by the image processing is stored in the storage unit. Compared with the shape of the surgical instrument stored in 52, it is preferable to delete the movement region when the two match. Thereby, noise can be removed more efficiently. Further, the area area increase rate, the area area increase duration, and the blood chromaticity range can be various ranges and can be set by the operator. The increase rate is large, the duration is long, and the chromaticity range is narrowed, so that the bleeding point detection condition becomes strict and only more serious bleeding can be detected. Further, a finer bleeding point can be detected by increasing the rate of increase, the duration time being short, and widening the chromaticity range. In this case, there is a high possibility of erroneous detection, that is, detection of a portion that has not bleeding as a bleeding point.

  The control unit 56 also estimates the amount of bleeding from the amount of change in the area of the bleeding region. Specifically, the control unit 56 stores in advance data indicating the relationship between the rate of change in the area of the bleeding region and the flow rate per unit time of blood bleeding from the affected area. Then, the amount of bleeding is estimated by comparing the rate of change in the area of the bleeding region calculated by the above-described procedure with the stored data.

  Moreover, it is preferable that the control part 56 displays a mark (mark) so that the area | region detected as a bleeding point may be enclosed. By displaying the mark in this way, it is possible to recognize the bleeding point. Further, it is preferable that the mark is displayed before bleeding starts when the moving image is reproduced.

  Hereinafter, an example of the detection method and the display method will be specifically described with reference to FIG. Here, FIG. 11 is an explanatory diagram for explaining an example of a method for detecting a bleeding point. In addition, FIG. 11 is displaying the image from the time T1 to the time T4, and has shown the case where it is bleeding from one place. First, when the image at time T1 is compared with the image at time T2, a region having a change in area is detected. Thereafter, at time T3 when time elapses, the area of the bleeding portion becomes larger. Thus, when the area of the bleeding region continues to increase for a certain period of time from time T1 to time T3, the control unit 56 detects the bleeding region as a bleeding point. The control unit 56 detects the bleeding point as described above. At this time, the time point at which bleeding is first confirmed (time T1) is set as the bleeding start time, and the time point (time T3) at which the bleeding is determined is set as the bleeding check time.

  Further, at the time of image reproduction, the bleeding point is surrounded by a dotted circle mark between times T1 and T2 before the bleeding confirmation time, and the bleeding point is indicated by a solid circle between T3 and T4 after the bleeding confirmation time. Surround with the mark. Thus, by displaying the mark, the bleeding point can be easily recognized. Further, by switching the mark display method, it is possible to clearly know the bleeding confirmation time.

  Next, the case of using bleeding detection as a feature point will be described with reference to FIG. Here, FIG. 12 is a flowchart showing another example of processing by the medical image recording apparatus. The process shown in FIG. 12 is the same as the process shown in FIG. 5 except for the feature point detection process. Will be omitted, and the points peculiar to the processing of FIG.

  First, preparation similar to the above processing is performed. When the preparation is completed, the medical image recording apparatus 12 determines whether there is a recording start instruction as Step S12. If it is determined in step S12 that there is no recording start instruction (No), the medical image recording apparatus 12 performs the determination in step S12 again. If it is determined in step S12 that there is a recording start instruction (Yes), the medical image recording apparatus 12 starts recording in step S14.

  When the medical image recording apparatus 12 starts recording in step S14, it determines in step S50 whether there is bleeding. Whether or not there is bleeding is determined based on the analysis result of the acquired image as described with reference to FIG. If it is determined in step S50 that there is no bleeding (No), the medical image recording apparatus 12 proceeds to step S26.

  If it is determined in step S50 that there is bleeding (Yes), the medical image recording apparatus 12 sets a time point before bleeding as a feature point in step S52. In the case of this embodiment as well, the setting of the time point before bleeding is not particularly limited, and any setting may be made. For example, what is necessary is just to set the fixed time (0.5 second before, 1 second before, 5 seconds before) the time of the bleeding determination to be before bleeding. Further, the time point at which the determination of whether or not bleeding is started (that is, the time point when the comparison of the areas is started) may be made before bleeding. If the medical image recording device 12 determines that the time before bleeding is a feature point in step 52, the medical image recording device 12 proceeds to step S26. Note that the processing after step S26 is the same as the processing of the flowchart shown in FIG.

  In this manner, by detecting the feature points based on the occurrence of bleeding (presence / absence of bleeding), it is possible to reproduce an image from the time when a change in the affected area occurs. Thereby, when bleeding (that is, a problem) occurs, the cause of bleeding can be grasped in a shorter time by reproducing the image from before bleeding. In addition, various effects similar to those described above can be obtained.

  Here, in the above-described embodiment, the feature point is any one of the use of the surgical tool, the abnormality of the biometric data, and the occurrence of bleeding. However, these multiple factors may be detected as the feature points. In other words, if a surgical tool is used or if there is an abnormality in biometric data, it may be detected as a feature point. If a surgical tool is used, if there is an abnormality in biometric data, or if bleeding occurs, it will be detected as a feature point. You may make it do.

  By detecting a plurality of factors as feature points in this way, the medical image recording apparatus 12 can set the cue point of an image (video) that the operator may desire to reproduce during the operation, The entry can be automatically performed without omission, and a necessary image can be reproduced in a short time by reproducing the feature point selected from a plurality of feature points as a base point. Hereinafter, a description will be given with reference to FIG. Here, FIG. 13 is an explanatory diagram showing the relationship between the feature points detected by the medical image recording apparatus and the recording data. FIG. 13 shows a case where a use is made as a feature point when there is use of a surgical tool, abnormality of biometric data, or occurrence of bleeding.

  When various factors are detected, by detecting them as feature points, a plurality of feature points can be detected during the operation as shown in FIG. FIG. 13 shows recording data and feature point data of surgery performed from 14:00 (PM 2 o'clock) to 16:00 (PM 4 o'clock). In the operation shown in FIG. 13, the medical image recording apparatus 12 detects that the instrument (surgical instrument) A is used at 14:10 as a feature point, and uses the instrument (surgical instrument) B at 14:40. This is detected as a feature point. In addition, bleeding at 14:20 is detected as a feature point. Further, an increase in blood pressure at 15:00 (that is, the blood pressure has exceeded a predetermined range as biometric data) is detected as a feature point.

  In this way, by detecting multiple factors as feature points, it is possible to reproduce images from the time each factor occurred during surgery, making it easier to grasp the problem and how to solve the problem. It becomes possible to grasp more easily. Further, by detecting a plurality of factors as feature points in this way, the flow of surgery can be grasped from the display of these feature points.

  In the above embodiment, the use of a surgical tool, abnormal biological data, and the occurrence of bleeding are detected as characteristic points. However, the present invention is not limited to this, and features analysis results that may cause problems in patients. What is necessary is a dot.

  The feature point detection condition may be set by the operator, and unnecessary feature points may be canceled by operation. Further, detection and setting of feature points may be performed after recording data. That is, during the operation, only the recording data may be obtained, and after the operation is completed, for example, when there is a margin in processing capability, the analysis may be performed to detect the feature points.

  In the above embodiment, the medical image recording apparatus 12 can reduce the possibility of affecting other devices of the medical system 10 and can smoothly use other devices. However, the present invention is not limited to this. Although the above effect cannot be obtained, the connection may be made in an electrically connected state, and information may be exchanged by transmitting and receiving an electric signal, for example.

  In the above embodiment, since the value and effectiveness as information can be further increased, an endoscope image, an operating room image, biological information, and information on the use of a surgical tool are used. The number of images to be acquired and the type of information are not particularly limited as long as at least one moving image and information capable of detecting feature points can be obtained. Further, when the feature point can be detected from the moving image, the medical image recording apparatus 12 may be configured to acquire only one moving image.

  As described above, the medical image recording apparatus according to the present invention is useful for recording and reproducing medical moving images, and is particularly suitable for reproducing surgical images.
