Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an endoscopic imaging system, and particularly to an endoscopic imaging system equipped with a data imprinting function.

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 viewfinder 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 data in the camera's viewfinder is different from the display of the imprinting device. When a doctor instructs the doctor to input other data related to the data previously ordered, the data imprinting device cannot find the previous data, so it is necessary to confirm with the doctor the data before the related data can be entered. This causes inconvenience in data entry.

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

The present invention will be described in detail 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. The connector 12 of the endoscopic pleasure IO is connected to the light source unit 14. The data imprinting device 16 includes a display panel I8 and a keyboard 20.
is provided. Operation panel 2 of data imprinting device Z6
0 is provided with, for example, a liquid crystal display 18 and each rice key.

According to the block circuit of data imprinting device z6, CP
U2B, ROM 30 and RAM 92 are connected to interfaces (I/F) 43, 44, 45 and serial interface (I/F) 42 via pass lines. Engineering/F 43 is the display driver 36 and keyboard 38
connected to. Display driver 36 is connected to display unit 34 . I/F 44 is connected to display unit 35 via display driver 37. I/F 4 s is connected to the 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. The light source unit control circuit 50 controls the control circuit of the data imprinting device 16 (
Serial I/F s connected to the input/output section of Figure 3)
g is connected to the pass line 62. A ROM 52* RAM 52 and a CPU 64 are connected to the pass line 62, as well as a clock circuit 56 via an I/F'59. Further, the pass line 62 is connected to the I/F 82 of the camera control circuit 70 via the r/F ty o and the transmission line 61. This I/F 82 is connected to a pass line 86. The pass line 86 includes a ROM 72, a CPU 73. RAV
L74 is connected, and also connected to the display unit 76 via the display driver 78. A data switch 80 is connected to the pass line 86 via the line 11184.

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

First, when the keys on the operation panel 20 of the data imprinting device 10 are operated and marking data such as date, patient initial, gender, age, medical record number, etc. is specified, the marking data is read from M54 to R and the display driver The image is supplied to the imprinting display unit 34 via 36. This display unit 34 emits light according to the marking data. When the marking data display on the display unit 34 is photographed by a camera 24 mounted on 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 check the marking data before imprinting the data, press the 1st to 4th line keys to display the marking data line by line. 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 II is a camera that has already captured the marking data.

The data imprinting device 1 allows a doctor to set data regarding a predetermined region while observing the inside of the body cavity through the endoscope camera Ilf.
When the nurse who is operating 6 is instructed, the nurse operates the keys on the operation panel 20 and inputs body part data. The part data is sent to the light source unit control circuit 50 via the serial number/F'42.
The data is transferred to the RAM 54 and stored in the RAM 54. At this time, the part data is displayed on the display panel I8. 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 6I. In the camera control circuit 70, the part data is stored in R and M74 and displayed in the viewfinder. The part data displayed on the display unit 76 is imprinted onto the film by the release operation, but when there is no need to imprint this part data, the data switch 80 is operated. When the doctor instructs different body part data, the nurse sets the instructed data in the data imprinting device. This new part data is transferred to the light source unit control circuit 50 and camera control circuit 70 through the operations described above. In this case, in the data imprinting device Z6, the previous data is updated with new data, and the updated data becomes data related to 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 imprint scribing data on another camera using the data imprinting device I6 in the above operating state, the data imprinting device 16
The display contents of the display panel 18 change. However, at this time, the endoscopic camera z1 displays the data immediately before the request for marking data for another camera, and therefore the display contents of the endoscopic camera IZ and the display panel I8 of the data imprinting device 16 are different. different.

In this state, when the doctor instructs the input of four-speed data 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 Z8.

As a result, the display in the viewfinder of the endoscopic camera 11 and the display on the display panel 18 can be matched, and the nurse can
8. Confirm the displayed data and set the newly instructed related data. As a result, the newly set related data is transferred to the endoscope camera 11 and displayed in the finder.

At this time, the raft mode is updated in data imprinting device #16.

As described above, when the data imprinting device sets data that is different from what is displayed in the viewfinder of the endoscope camera, the data mode given to the endoscope camera immediately before this data setting is the last mode and the data is imprinted. Since the data is retained in the device, when data is set for the endoscope camera again, the display contents of the endoscope camera and the data imprinting device can be matched by calling the last mode.

Although the arrow keys are operated to call up the last mode, the last mode may also be called up periodically at regular intervals. In addition, when the endoscope camera is attached or detached, the endoscope camera control circuit is reset, but by synchronously inquiring the last mode from the light source unit to the data imprinting device, the endoscope camera data can be transferred to the data imprinting device. The last mode can be automatically set, and the data of both can be matched. In this case, even if the camera data changes due to noise, it is reset using the last mode data.
