Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an endoscope system including an endoscope, an endoscope camera, and a light source device.

[Problems to be solved by conventional technology and invention]

Conventionally, when endoscopic photography is performed, the patient's name, the date of photography, etc. are written on the photographic film using an iron pen. This work is troublesome because the film width is narrow, and it is difficult to write a lot of data. In order to improve this inconvenience, a method was proposed in 1972, in which the data to be entered was written on a piece of paper and the data was photographed in the first frame of the film using an endoscope fixed to a jig.
Disclosed in No. 162016. However, with this method, a piece of paper with data written on it must be prepared for each film, and since the paper piece has a high reflectance, it is necessary to change the exposure constant between observation and photography, which is time-consuming. Another method is to use a camera equipped with a data imprinting function, but in this case, data must be set for each film using a key switch, which is time-consuming. Furthermore, since the data is imprinted onto the film, the number of frames in which the actual subject can be imprinted is reduced.

It is an object of the present invention to have a printing function for reading data from a patient card and printing the read data on at least one of a film cassette and film stored in a camera, and to confirm the printed data without removing the film from the camera. It is an object of the present invention to provide an endoscope that can be easily managed in medical records and the like.

〔Example〕

As shown in FIG. 1, an endoscope camera 1 is attached to an eyepiece of an endoscope 2, and a connector 2a of the endoscope 2 is connected to a light source device 3. The endoscope 2 is provided with a light guide, an image guide, and optical system components (not shown), and a signal line 4 is also connected to the eyepiece section 1.
a to the connector portion 2a. This signal line 4 is connected to the printing device 6 via the signal line of the camera 1 at the eyepiece 1a. This printing device 6
are arranged opposite to the back surface of the film cassette 5. In the connector portion 2a, the signal line 4 is connected to the processing circuit 8 via a signal line within the light source device 3. Connected to this processing circuit 8 are a clock device 7 that generates date data such as day, hour, minute, etc., and a card reading device 9 that reads data from a patient card 21.

In the endoscopic camera 1, as shown in FIG. 2, a print head 11 is provided so as to come into contact with a print sheet 10 attached to the back of a film cassette 5. The print head 11 is, for example, a heat-generating print head composed of a plurality of heat-generating elements arranged in a line in the vertical direction. Such a print head 11 is movably supported by a guide rail 12 and attached to a moving belt 13c that spans rotating rollers 13a and 13b. roller 13
A motor 14 is coupled to a, and the rotational force of the motor 14 rotates the roller 13a. Motor 1
4 is connected to the motor drive circuit 15. A head drive circuit 16 is connected to the print head 11. The input ends of motor and head drive circuits 15 and 16 are connected to bus line 17. This bus line 1
7 has a CPU 18, memory 19 and communication circuit 20
is connected.

In FIG. 3, the patient card reading device 9 provided in the light source device 3 has a light transmitting guide member 22 and a light receiving guide member 23, which are provided opposite to the back surface of the patient card 21. Light receiving guide member 2
Reference numeral 3 is composed of a plurality of light guide elements provided corresponding to the heat generating elements of the print head 11. At the light output end of the light guide element, there is a light receiving element, e.g.
A phototransistor Tr is provided respectively. These transistors Tr are connected to an input buffer 25 of the processing circuit 8 via a waveform shaping circuit 24. Input buffer 25 is connected to bus line 26 .
This bus line 26 includes a clock device 7, a CPU 27,
A memory 28 and a communication circuit 29 are connected.

In the endoscope system shown in FIGS. 1 to 3, when the patient card 21 is inserted into the card reading device 9 of the light source device 3, the patient number and patient name written on the card are read out. That is, light passing through the light transmitting guide member 22 illuminates the back surface of the patient card 21, and reflected light from the patient card 21 corresponding to the irregularities of the card enters the light receiving guide member 23. The reflected light has a large amount of light on the flat portion of the card 21, and has a small amount of light on the concave portion where characters are written. Such a difference in the amount of light is detected by the phototransistor Tr, and the detected signal is waveform-shaped by the waveform shaping circuit 24 and stored in the input buffer 25. All data of the patient card 21 collected in this input buffer 25 is stored in the memory 28. When reading of the card data is completed, the card data stored in the memory 28 is sent to the printing device 6 of the camera 1 by the communication circuit 29 via the signal line 4 together with the date data of the clock device 7. In this printing device 6, card data and date data are stored in a memory 19 shown in FIG. When such data transfer is completed, the data stored in memory 19 is sent to print head drive circuit 16. Also, at this time, a motor drive command is issued to the motor drive circuit 15 from the CPU 18 . A motor drive circuit 15 rotates the motor 14, and a print head drive circuit 16 operates the print head 11 in response to input data. Print head 11
is the belt 13 that moves due to the rotation of the roller 13a.

In addition, in the camera 1, a photographing device 32 that performs a series of photographic operations, that is, mirror up, photometry, shutter operation, mirror down, film winding, and display of the number of film sheets, is connected to a bus line 17 as shown in FIG. be done. In this embodiment, when a predetermined number of films have been photographed, two films are unwinded and a film end signal is sent to the bus line 17. When the CPU 18 detects the film end signal, it issues a data transmission request to the light source device 3 via the communication circuit 20 to send print data. When the light source device 3 transmits print data in response to the data transmission request, the data is printed on the film cassette according to the same operation as described above. Furthermore, photographing device 3
2 operates in response to the operation of the release switch 31. Furthermore, the printer 30 may be incorporated into the light source device 3 or may be provided separately. When printing, printing may be performed on a printing paper 10 pasted on the back side of the film 33 as shown in FIG. 6. For example, as shown in FIG. , may be printed on the paper 10 or directly on the film 33. Further, in this embodiment, the data printed on the print paper 35 by the printer 30 is
By pasting it on the chart 34 as shown in the figure, the photographed image can be memorized and compared with the data on the printing paper 10 pasted on the developed film 33. Furthermore, the printing paper 10 may be attached to the side or top of the film cassette.

The printing head need not be of the heat generating type and may be of any type such as a discharge type, a normal dot impact type, or an inject type.
Further, the signal line 4 is not limited to a wired one, and may be a wireless one, an optical fiber, or an acoustic medium. Furthermore, the signal line 4 does not have to pass through the interior of the endoscope. The communication circuits 20 and 29 may be of any communication method such as full duplex or half duplex.

The data printed on the film cassette is not limited to patient card data and clock device data, or may be either one of them.
For example, when two or more films are photographed for one patient, the film number or the time of photographing can be printed. The method for inputting patient data is not limited to the patient card described above, but may also use a magnetic or optical disk, tape, or the like. The reading device may be a photoelectric reading device or a magnetic reading device.

Instead of directly printing the graphics read from the patient card onto the film cassette using the print head, the processing circuit distinguishes the characters shown in the graphics and converts them into character codes, such as ASCII codes, before sending the data to the camera. For example, the communication time is shortened, the error rate in communication is reduced, and the memory capacity of the printing device can be reduced. The card reading device may be configured separately from the light source device. Further, the clock device may be built into the camera. Furthermore, the printing is not limited to characters, but may also be performed by encoded, for example, bar codes.
