Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data imprinting device used, for example, in an endoscope imaging system.

An endoscope photographing system equipped with a data imprinting function is provided with an endoscope, an endoscope camera, a light source unit, and a data imprinting device. When using such an endoscopic imaging system, the doctor operates the endoscope, observes the inside of the body cavity through the endoscope camera's viewfinder, and instructs the nurse to copy the data as necessary. Data is transmitted to the endoscopic camera by operating keys on the embedded device. The data is displayed in the window of the endoscopic camera, and the doctor checks the displayed data and records the data on film as necessary. In this state,
When a data input operation is performed to store different data using the data imprinting device, the display of the data imprinting device in the camera viewfinder may differ, and the doctor operating the endoscope will When an instruction is given to input other data related to the data instructed, the data imprinting device does not know the previous data, so the related data cannot be entered and the previous data must be confirmed with the doctor, which is inconvenient for data entry. occurs.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a data imprinting device that easily matches the display in the viewfinder of an endoscope camera and the display on the data imprinting device.

Embodiments of the present invention will be described below with reference to the drawings.

According to the endoscopic imaging system shown in FIG. 1, an endoscopic camera 11 is attached to the eyepiece of an endoscope 10.
A connector 12 of the endoscope 10 is connected to a light source unit 14. The data imprinting device 16 is provided with a connection tube 22 to which an operation panel 20 and an endoscope camera are connected. As shown in FIG. 2, the operation panel 20 is provided with a display panel 18 made of, for example, a light emitting diode and a keyboard on which various keys are arranged.

According to the block circuit of the data imprinting device 16 shown in FIG.
RAM 32 is connected to interfaces (I/F) 43, 44, 45 and serial interface (I/F) 42 via bus lines. I/F
43 is connected to the display driver 36 and keyboard 38. The display driver 36 is the display unit 34
connected to. I/F 44 is connected to display unit 35 via display driver 37. I/F4
5 is connected to a camera control circuit via a transmitting/receiving circuit 40. Serial I/F 42 is connected to the light source control circuit.

FIG. 4 shows a control circuit 50 for the light source unit 14 and a control circuit 70 for the endoscopic camera 11. In the light source unit control circuit 50, a serial I/F 58 connected to the input/output section of the control circuit (FIG. 3) of the data imprinting device 16 is connected to the bus line 62. The bus line 62 has a ROM 52,
RAM 54 and CPU 64 are connected, and clock circuit 56 is also connected via I/F 59. In addition, the bus line 62 is connected to the I/F 60 and the transmission line 61.
It is connected to the I/F 82 of the camera control circuit 70 via. This I/F 82 is connected to a bus line 86. Bus line 86 has ROM72 and CPU7
3.When RAM74 is connected, I/F83,
It is connected to the display unit 76 via a display driver 78. A data switch 80 is connected to a bus line 86 via an I/F 84.

Next, the operation of the endoscopic imaging system will be explained.

First, the operation panel 2 of the data imprinting device 16
When the 0 key is operated and marking data such as date, patient initial, gender, age, medical record number, etc. is instructed, the marking data is read out from the RAM 32 and supplied to the imprinting display unit 34 via the display driver 36. be done. This display unit 34 emits light according to the marking data. When the marking data display on the display unit 34 is photographed by the camera 24 attached to the connecting tube 22 of the data imprinting device 16, the marking data is imprinted on the first frame of the film of the camera 24. If you want to confirm the marking data before imprinting the data, press the 1st to 4th line keys on the keyboard provided on the operation panel 20, and the marking data will be displayed line by line on the display unit 35 of the display panel 18. It can be confirmed by this. Also, camera 24
You can also check the marking data by looking at the window. Once the marking data has been captured, the camera 24 is attached to the endoscope 10 and a transendoscope image can be captured. The endoscope camera 11 is a camera that has already captured the marking data.

While observing the inside of the body cavity through the endoscopic camera 11, the doctor instructs the nurse operating the data imprinting device 16 to set data regarding a predetermined region, and then operates the keys on the operation panel 20 to input the region data. input. The part data is transferred to the light source unit control circuit 50 via the serial I/F 42.
It is stored in RAM54. At this time, the part data is displayed on the display panel 18. In the light source unit control circuit 50, the part data is transferred to the camera control circuit 70 via the I/F 60 and the transmission line 61. In the camera control circuit 70, part data is
It is stored in the RAM 74 and displayed in the finder. The part data displayed on the display unit 76 is imprinted onto the film by the release operation, but the data switch 80 is operated when it is not necessary to imprint this part data. When the doctor instructs different body part data, the nurse sets the instructed data in the data imprinting device. This new part data is transmitted to the light source unit control circuit 50 and the camera control circuit 7 by the operation as described above.
Transferred to 0. In this case, in the data imprinting device 16, the previous data is updated with new data, and the updated data becomes data regarding the last mode. The last mode is either free data mode or date data mode.

When the nurse operates the operation panel 20 in order to use the data imprinting device 16 to imprint scribing data on another camera in the above operating state, the display contents on the display panel 18 of the data imprinting device 16 change. However, at this time, the endoscope camera 11
, the data immediately before the request for marking data to another camera is displayed, and therefore the display contents on the display panels 18 of the endoscope camera 11 and the data imprinting device 16 are different. In this state, when the doctor instructs input of data related to the most recently instructed site data, the nurse operates the arrow keys. When the arrow keys are activated, the last mode is called and the data most recently instructed by the doctor is displayed on the display panel 18. As a result, the display in the viewfinder of the endoscopic camera 11 and the display on the display panel 18 are matched, and the nurse confirms the display data on the display panel 18 and sets the newly instructed related data. As a result, the newly set related data is transferred to the endoscope camera 11 and displayed in the viewfinder. At this time, the last mode is updated in the data imprinting device 16.

In this embodiment, the arrow keys are operated when calling the last mode, but the last mode may be called periodically at regular intervals. In addition, the endoscope camera control circuit is reset when the endoscope camera is attached or detached, but the data of the endoscope camera can be reset by periodically inquiring the last mode from the light source unit to the data imprinting device. The last mode of the imprinting device can be automatically set, and data matching between the two can be achieved. Furthermore, in this case, even if the camera data changes due to noise, it is reset using the last mode data. Furthermore, if the display panel of the data imprinting device and the display in the viewfinder of the camera are different, notification may be made by a notification means provided near the display panel.

As described above, the data imprinting device of the present invention is provided with means for storing the last mode output last to the first endoscopic camera and means for calling the last mode on the display panel. Therefore, the display contents of the endoscopic camera and the data imprinting device can be matched as appropriate.
