[Problems to be solved by the invention]
In the endoscope shape detection apparatus, a marker including a coil that generates a magnetic field is arranged near a patient that is an entrance of an endoscope. The magnetic field generated by the marker is read by an antenna provided in the center of the endoscope shape detection device main body, and the position of the marker 5 is set on the monitor 30 as the insertion start point of the endoscope 4 as in the example shown in FIG. indicate. Thus, in the endoscope shape detection device, the insertion position of the endoscope can be confirmed by the marker. If the position of the tip of the endoscope is known from the position of the coil built in the end of the endoscope among the coils built in the insertion portion of the endoscope whose antenna has detected a magnetic field, the marker The length from the position to the tip of the endoscope, that is, the insertion length of the endoscope is known. In the example of the image of FIG. 3, as shown by the encircled and highlighted portion, in the endoscope shape detection device, the insertion length of the endoscope is set together with the insertion shape of the endoscope. As a length, it is displayed on the monitor 30 of the endoscope shape detection device 3 in the form of, for example, how many cm.
[0006]
Conventionally, when creating a report of endoscopic examination results, a copy of an observation image of a lesion is pasted on a paper chart on which a sketch drawing of the examination site is written. First, when a lesion is found during endoscopy, the insertion length is recorded and stored. Knowing the insertion length of the endoscope at the time the lesion is found, the position of the lesion is located from the entrance of the examination site based on the standard shape and size of the examination site. It can be generally judged whether to do. Therefore, when the report of the test result is created after the test is completed, the sketch is marked on the sketch diagram as the position of the lesion. By connecting the marked part and a copy of the observation image of the lesioned part with a line, it is possible to know which part the attached observation image belongs to. In this way, a method has been adopted in which a report is created after the examination is completed using the insertion length data of the lesioned endoscope.
[0007]
In the examination of the large intestine and small intestine, dozens of polyps are often found in one examination. In such a case, if a copy of the observed image of the lesioned part is manually pasted based on the memory of the insertion length after the examination is completed, a very long time is required. In addition, in such a method of using insertion length data of an endoscope, it is difficult to say that insertion length data of an endoscope is sufficiently utilized as electronic data. Furthermore, it is preferable to manage the results of endoscopy with an electronic medical record also from the viewpoint of the tendency of digitization of medical records in recent years.
[0008]
By sharing the data possessed by each medical device, the present invention makes effective use of these data, shortens the time required for report creation, and reduces the work load. It is aimed.
[0009]

The electronic endoscope apparatus 2 and the endoscope insertion shape detection apparatus 3 transmit RGB video signals to the medical image recording apparatus 1 and are used to transmit observation image data of the electronic endoscope apparatus 2. .
[0016]
As shown in FIG. 1, the medical image recording apparatus 1 stores a sketch diagram in a predetermined memory or the like such as a non-volatile memory (endoscopic observation image recording means / endoscope insertion length recording means) 60 in advance. ing. The sketch diagram is electronic data representing schematic diagrams of the stomach, esophagus, large intestine, and the like, for example, and is a diagram representing the shape of a part to be examined by the electronic endoscope apparatus 2.
[0017]
As described above, since the endoscope insertion shape detection device 3 is connected to the electronic endoscope device 2, the length from the marker indicating the display start point of the endoscope to the endoscope, that is, the internal endoscope You know the insertion length of the endoscope. If the insertion length of the endoscope is known, it is possible to know at what point the percentage of the endoscope from the entrance of the organ being examined, that is, how many cm from the entrance of the examination site. This is because the average size of each organ is known information. The electronic endoscope device 2, the endoscope insertion shape detection device 3, and the medical image recording device 1 are photographed by the electronic endoscope device 2 when a lesion is found by connecting the devices. Based on the insertion length data of the endoscope insertion shape detection device 3, the data of the observed image of the lesioned part can be immediately linked to the sketch diagram on the monitor 52 of the medical image recording device 1 and displayed.
[0018]
The process of taking an observation image taken with an endoscope into a sketch diagram using insertion length data will be specifically described. FIG. 2 is a flowchart showing processing for linking the sketch diagram and the observation image of the endoscope. In the following, S1, S2,... Shown in parentheses in the sentence represent each step in FIG.
[0019]
As a premise, it is assumed that an examination site is specified and a sketch diagram is displayed on the monitor 52 of the medical image recording apparatus 1. When the endoscopy is started, endoscope insertion shape data and insertion length data of the electronic endoscope device 2 are sequentially transmitted from the endoscope insertion shape detection device 3 to the medical image recording device 1. From the electronic endoscope apparatus 2, observation image data captured by an endoscope connected to the electronic endoscope apparatus 2 is sequentially transmitted to the medical image recording apparatus 1. In the medical image recording apparatus 1, observation image data and insertion length data transmitted from the electronic endoscope apparatus 2 and the endoscope insertion shape detection apparatus 3 as needed are stored in a non-volatile memory (endoscopic observation image recording means / internal (Scope insertion length recording means) 60 is recorded in a predetermined memory such as 60, and is monitored and managed.
[0020]
When a user of the medical image recording apparatus 1 finds a lesioned part in an observation image of an endoscope, the user designates an observation image in which the lesioned part is photographed with a pointing device or the like (S1). ). When receiving the instruction for specifying the observation image, the medical image recording apparatus 1 writes the observation image in the memory. Based on the time stamp of the written observation image data, the insertion length data received from the endoscope insertion shape detection device 3 is specified (S2). From the read insertion length data, the position of the lesion is calculated from the entrance of the examination site, and the corresponding part is marked on the sketch diagram (S3).
[0021]
The medical image recording apparatus 1 reads the designated observation image data from the memory, reduces the observation image data to a size that fits outside the frame of the screen on which the sketch diagram is displayed, and the electronic endoscope apparatus 2 shown in FIG. Like the example of the sketch drawing of the report, which is displayed by linking the taken observation images, it is imposed on the screen displaying the sketch drawing (S4). When the designated observation image data is imposed on the screen of the monitor 52, the marked portion of the sketch diagram and the reduced observation image are connected by the lead-out line 6 in FIG. 4 so that the user can view them corresponding to each other. Like that. The imposed image is displayed on the thumbnail (S5). When the user clicks on a certain portion of the thumbnail, a corresponding observation image having a normal size can be displayed on the monitor 52. The observation image data received from the electronic endoscope apparatus 2 has a different format depending on the hospital, such as a JPEG format, but can be inserted regardless of the file storage format.
[0022]
As described above, according to the present embodiment, every time a lesion is found, the position of the lesion does not need to be designated in the sketch diagram, and is automatically input. For this reason, operation becomes simple. Since the position of the lesion can be specified without depending on the memory of the person who performs the endoscopy, even if the number of lesions is large, reliable recording is possible.
[0023]
An image representing the insertion shape of the endoscope and the endoscopic observation image may be simultaneously displayed on the monitor. The user of the medical image recording apparatus 1 can freely select whether to display the endoscope insertion shape and the observation image at the same time or to display each image separately.

Therefore, when receiving the scope ID data, the medical image recording apparatus 1 side can specify which part is to be examined from the scope ID value.
[0027]
Since the medical image recording apparatus 1 stores in advance sketch drawings of each examination site, the medical image recording apparatus 1 sketches an organ for inspecting the sketch drawing of the examination site specified by the scope ID data. As a figure, it can be automatically displayed on the monitor 52 of FIG. There is no need for the user to specify and display a sketch drawing of the examination site.
[0028]
In addition, by recording the insertion length of the endoscope together with the patient ID in the medical image recording apparatus 1, the report of the examination result created by the present embodiment can also be used for the follow-up observation of the lesioned part. . For example, it can be used for re-examination after half a year when a polyp is excised. Since the insertion length data of the endoscope provides a rough indication of where the polyp is removed, the time required for reexamination can be reduced. This is also effective when multiple doctors are in charge of examining one patient.
[0029]
The image representing the insertion shape of the endoscope and the endoscope observation image may be displayed on the monitor of the medical image recording apparatus 1 at the same time. The user of the medical image recording apparatus 1 can freely select whether to display the endoscope insertion shape and the observation image at the same time or to display each image separately.
