  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 is a diagram showing a configuration of an endoscope diagnosis system according to Embodiment 1 of the present invention. The endoscope diagnosis system 1 in FIG. 1 includes an endoscope main body 2, an endoscope apparatus 3, a base unit 4, an input device 6, and a monitor 8. FIG. 1 shows an example in which an optical diagnostic device including an optical probe 10 and a base unit 4 is mounted as an optional diagnostic device.

  The endoscope main body 2 includes a flexible long introduction portion 21 formed so as to be capable of being introduced into a body cavity, an operation portion 22 provided at a proximal end portion 21a of the introduction portion 21, and an operation portion 22. And the cable 23 that connects the introduction unit 21 and the endoscope apparatus 3 so as to communicate with each other.

  The introduction portion 21 has flexibility over substantially the entire length so that it can be easily bent following the curvature of the body cavity when entering the inside of the body cavity. In addition, the introduction part 21 has a mechanism (not shown) that can bend a certain range (operable part 21c) on the tip part 21b side at an arbitrary angle in accordance with the operation of the knob 22a of the operation part 22.

  As shown in FIG. 2 which is a perspective view of the distal end portion 21b, the introduction portion 21 includes a camera CA, a light guide LG, a channel CH, and a marking unit MU.

  The light guide LG guides light (visible light) emitted from the illumination light source 31 of the endoscope device 3 to the distal end portion 21b and emits the light from the distal end portion 21b.

  The camera CA is an electronic camera provided with a solid-state image sensor, images an area illuminated with light emitted from the light guide LG, and transmits a signal (imaging signal) to the endoscope apparatus 3.

  The marking unit MU will be described later.

  The channel CH is a lumen having a diameter of, for example, 2.6 mm formed in the introduction portion 21 so as to communicate with the introduction port 22 b formed in the operation portion 22. Various devices for observing the affected area, diagnosing the affected area, performing surgery on the affected area, and the like can be inserted into the channel CH. For example, as shown in FIG. 1, a probe main body 11 for optically inspecting and diagnosing a target part in a body cavity can be inserted.

  As shown in FIG. 1, the probe main body 11 is a long flexible linear member extending from the probe base end portion 11a to the probe tip end portion 11b. The probe body 11 is connected to the base unit 4 via a connector provided at the probe base end portion 11a. The probe main body 11 is introduced into the body cavity by being inserted into the channel CH, guides the laser light emitted from the laser 41 of the base unit 4, and irradiates the light to the observation target site (for example, the affected part) in the body cavity. To be emitted.

  Further, the probe body 11 receives reflected light from the site to be observed and guides the light to the spectroscope 42 of the base unit 4. The light guided to the spectroscope 42 is subjected to spectrum analysis by the spectroscope 42. The spectrum analysis result is subjected to image processing and the like by a CPU (Central Processing Unit) 43a of the computer 43 and displayed on the monitor 7 as a graph. The CPU 43a may determine a medical condition and the like, and the determination result may be stored in the memory 43b and displayed on the monitor 7. The execution and setting of various analyzes and determinations in the computer 43 can be performed by operating the input device 5 (for example, a keyboard or a mouse).

  In the present embodiment, as described above, the configuration using the optical probe 10 and the base unit 4 that performs the analysis by the spectroscopic method is exemplified as an optional device for combining with the endoscope diagnosis system 1. These uses are examples and are not essential.

  As shown in FIG. 2, the marking unit MU is embedded in the distal end portion 21 b of the introduction portion 21 of the endoscope main body 2 and can be introduced into the body cavity together with the endoscope main body 2.

  As shown in FIG. 3A, a large number of APC (Argon Plasma Coagulation) applicator elements 51 are arranged in a matrix at the tip of the marking unit MU.

  APC applicator elements (hereinafter simply referred to as “elements”) 51 are individually driven by a marker driver 32 (drive unit) of the endoscope apparatus 3. Each element 51, when driven, injects argon gas and causes a high-frequency current to flow through the argon gas as a medium, thereby cauterizing (solidifying) the living tissue where the argon gas is blown. Therefore, an arbitrary mark (FIG. 3C) can be marked on the site by driving the arbitrary element 51 in a state where the marking unit MU is brought close to the arbitrary site in the body cavity (FIG. 3B).

  In this embodiment, APC, which is well-known as a non-contact type cauterization method for cauterizing living tissue in a body cavity by high frequency, is used as a mark marking method, but methods other than APC can also be used. is there. For example, an optical cauterization method using a laser, an indentation method using suction or pressing, an implant method using a plate of a biocompatible material, or a tattoo method using a dye of a biocompatible material can be used.

  In this embodiment, the matrix type two-dimensional code is adopted as the mark type, but a different type can also be used. For example, bar codes, characters or symbols can be used.

  The endoscope device 3 includes a video processing unit 33, an image processing unit 34, a storage device 35, and a CPU 36 in addition to the illumination light source 31 and the marker driver 32 described above, and is connected to the input device 6 and the monitor 8. ing.

  The video processing unit 33 receives an imaging signal from the endoscope body 2, performs predetermined signal processing on the imaging signal, and outputs the processed signal to the monitor 8 as an endoscope video signal. A video (endoscopic video) based on the endoscope video signal is displayed on the screen of the monitor 8. That is, when the affected part in the body cavity is imaged, the image is displayed on the monitor 8. The video processing unit 33 also outputs the endoscope video signal to the image processing unit 34.

  The image processing unit 34 generates a patient information image signal indicating an image of patient information, and superimposes the patient information on the endoscope video on the screen of the monitor 8. The image processing operation will be described later.

  The storage device 35 is a storage device such as an HDD (Hard Disk Drive) built in the endoscope device 3. Note that the storage device 35 does not have to be built in the endoscope device 3, for example, may be externally attached to the endoscope device 3, or exists on a communication network. It may be.

  The CPU 36 is a control unit that controls the operation of each unit in the endoscope apparatus 3. The execution and stop of the control of the CPU 36 and the input of various information to the endoscope device 3 can be performed by operating the input device 6 (for example, a keyboard or a mouse).

  Next, the marking operation executed in the endoscope diagnosis system 1 will be described. FIG. 4 is a flowchart for explaining the marking operation.

  First, identification information (affected part ID) of an affected part (marked target affected part) that is approaching the marking unit MU is selected (step S11).

  Here, the affected area ID is information for identifying an affected area that has been previously examined or treated. As shown in FIG. 5, the affected area ID is a database DB1, together with patient identification information (patient ID), information on the date and time when the examination or treatment for the affected area was performed, and information on the determination result about the examination or treatment. It is stored in the storage device 35. These pieces of information relating to the affected area (hereinafter collectively referred to as “affected area information”) are not limited to the information illustrated in FIG. 5, and may be any information that is useful for current or future diagnosis by a doctor. Also good. For example, image information or the like of an affected part imaged at the time of examination or treatment can be used as affected part information.

  The affected area ID can be selected, for example, by selecting any affected area ID after reading the information in the database DB1 from the storage device 35 and displaying the list on the monitor 8 by operating the input device 6. .

  The CPU 36 generates a mark pattern by applying a predetermined calculation algorithm to the affected area information corresponding to the selected affected area ID (step S12). Since the pattern of the mark is generated from information unique to the affected area to be marked, a different mark can be obtained for each affected area. Further, since the affected area information includes information (history information) related to past examinations or treatments for the corresponding affected area, a different mark can be generated if the information is changed. Therefore, when there are a plurality of pieces of history information for one affected part, it is possible to generate a common mark for the plurality of pieces of history information, or to generate a different mark for each piece of history information. .

  The generated mark pattern may be a pattern in accordance with a user instruction from the input device 6. Further, not only the affected part information but also other information (for example, the product serial number of the endoscope body 2 or related information generated from the electronic medical record about the patient) may be used to generate the mark pattern. good.

  In the present embodiment, the generation of the mark pattern means determining the element 51 to be turned on (driving state) at the time of marking and the element 51 to be turned off (non-driving state) at the time of marking. means. Therefore, for example, when 76 elements 51 are used in the marking unit MU as shown in FIG. 3A, the mark pattern information obtained as a result of pattern generation is information indicating on / off of each element 51. As an example of the mark pattern information, each element 51 is composed of 76 digits and the bit value of each digit is turned on / off (for example, bit value = 1 when on, bit value = 0 when off). A bit string indicating

  In this way, the CPU 36 assigns a unique mark to the affected area information.

  As shown in FIG. 6, the CPU 36 stores the generated mark pattern information in the storage device 35 as the database DB2 in association with patient information such as a patient ID and a patient ID (step S13). The databases DB1 and DB2 in FIGS. 5 and 6 may be integrated.

  Then, the marker driver 32 drives each element 51 according to the mark pattern information, whereby the marking unit MU marks a unique mark on or near the affected part to be marked (step S14). In addition, it is preferable that a mark is marked on the site | part surrounding an affected part as shown in FIG.

  The marking operation is executed in the endoscope diagnosis system 1 as described above.

  The combination of the storage device 35, the marker driver 32, and the marking unit MU involved in the marking constitutes a marking device that performs marking on or in the vicinity of the affected part in the body cavity of the patient.

  Next, an image processing operation executed in the endoscope diagnosis system 1 will be described. FIG. 8 is a flowchart for explaining the image processing operation.

  First, the image processing unit 34 receives an endoscope video signal from the video processing unit 33 (step S21). That is, the image processing unit 34 constitutes an acquisition unit that can acquire a video signal of the affected part.

  Then, the image processing unit 34 performs image recognition (for example, pattern matching, shape recognition, edge extraction processing, color extraction, or barcode recognition) on the endoscope video signal (step S22), and as a result, The position information of the mark marked at or near the affected part is acquired (step S23), and the pattern of the mark is specified (step S24). That is, what kind of mark is present in which part of the endoscopic video is detected by image recognition. That is, the image processing unit 34 constitutes a detection unit that detects a mark marked at or near the affected part using an endoscope image signal.

  It is assumed that the resolution of the endoscope diagnosis system 1 is at a level sufficient for mark detection. According to a trial calculation, assuming that the separation distance between the camera CA and the affected part is 5 mm, the angle of view is 140 degrees, and the number of pixels of the camera CA is 400,000 pixels square, the maximum is about 18 × 18 pixels per square mm. The mark of the code can be detected.

  After the mark detection, the image processing unit 34 refers to the databases DB1 and DB2. Then, the image processing unit 34 specifies the affected part ID from the mark pattern information representing the specified pattern, and extracts the affected part information corresponding to the detected mark from the database DB1 based on the affected part ID (step S25). . That is, the image processing unit 34 constitutes an extraction unit that extracts diseased part information from the databases DB1 and DB2 based on the detected marks.

  Then, the image processing unit 34 selects information to be displayed superimposed on the endoscopic video from the extracted affected part information (step S26). Selection may be made according to the information format such as character information or image information, or selection may be made based on the information content such as date / time information or determination result information. In addition, when a plurality of marks each marked at or near a plurality of affected areas are displayed and detected, a plurality of affected area information is extracted. In this case, any one of the plurality of affected area information is extracted. The affected area information may be selected. This selection may be made manually by the user using the input device 6.

  Then, the image processing unit 34 generates an affected part information image signal indicating the selected affected part information (step S27), and outputs the signal to the monitor 8 (step S28), whereby the affected part information is displayed on the screen of the monitor 8. It is displayed superimposed on the endoscope video. As a result, as shown in FIG. 9, it is possible to display on the screen of the monitor 8 a composite image in which the affected area information is superimposed on the endoscope image. That is, the combination of the video processing unit 33 that outputs an endoscopic video signal to the monitor 8 and the image processing unit 34 that outputs an affected part information image signal to the monitor 8 allows the affected part information to be displayed on the screen of the monitor 8 together with the endoscopic video. A display processing unit to be displayed is configured.

  As shown in FIG. 9, in the composite video, an identification display surrounding the detected mark is added, and the affected area information is adjacent to this identification display, thereby providing a basis for displaying the affected area information being displayed and the affected area information. Correspondence with the mark can be clarified.

  The displayed composite video may be stored in the storage device 35.

  Further, the affected area information superimposed on the endoscopic image may be displayed in a semi-transmissive state. Further, the affected area information may be displayed outside the frame of the endoscope image without being superimposed on the endoscope image on the screen of the monitor 8. The display position of the affected area information may be selectable by the user.

  In addition, the user may arbitrarily switch between a mode in which the endoscope video is displayed as it is on the screen of the monitor 8 and a mode in which the synthesized video is displayed on the screen of the monitor 8.

  In addition, when a plurality of marks each marked at or near the affected area are displayed on the screen of the monitor 8, affected area information corresponding to each of the plurality of marks may be displayed at the same time. In this case, it is preferable to display a plurality of marks and a plurality of affected part information in such a manner that the correspondence between each mark and each affected part information can be identified. The mode in which the correspondence relationship can be identified is, for example, color coding.

  As described above, the image processing operation is executed in the endoscope diagnosis system 1.

  The combination of the video processing unit 33 and the image processing unit 34 involved in the display of the composite video constitutes an observation apparatus that displays the video of the affected part for the doctor's observation. Moreover, the combination of this observation apparatus and the above-mentioned marking apparatus comprises an observation system.

  As described above, according to the present embodiment, the marking device assigns a unique mark to the affected area information, and stores the databases DB1 and DB2 in which the affected area information and the mark are associated with each other in the storage device 35. The marking unit MU marks the mark at or near the affected area. The observation apparatus receives the endoscope video signal, detects a mark using this signal, extracts affected part information from the databases DB1 and DB2 based on the mark, and uses the affected part information as an endoscope video signal. At the same time, it is displayed on the screen of the monitor 8. In other words, when the mark that symbolizes the affected area information is marked in advance in the vicinity of the affected area or the affected area, and then the affected area in the body cavity is imaged, the mark is automatically recognized and the affected area information is displayed together with the image of the affected area. indicate. Meanwhile, no particularly complicated manual work is necessary. Therefore, the affected part information useful for the diagnosis of the doctor can be provided to the doctor in a timely manner without increasing the work burden of the medical staff such as the doctor. As a result, it is possible not only to simplify the doctor's technique during the operation, but also to contribute to the doctor's quick and accurate judgment.

  In the present embodiment, the marking unit MU is attached to the endoscope body 2 and the observation device is built in the endoscope device 3, so that the same effect as described above is realized in the endoscopic surgical environment. can do.
