Description

Detailed Description of the Invention (Technical Field) The present invention relates to a data imprinting device used for imprinting a required data image onto a photographing medium for an endoscopic image when photographing an endoscopic image. In particular, it relates to an endoscopic imaging data imprinting device that can be used in combination with other devices and has multiple types of functions, at least some of which can be selectively realized depending on the combination state. .

[Prior art]

Generally, in endoscopic diagnosis, not only direct observation with the naked eye but also photography of endoscopic images is performed. In this case, in order to facilitate diagnosis, the photographic film contains not only endoscopic images of the inside of the body cavity, but also patient data such as the patient's name, gender, medical record number, and photographic data such as the part to be photographed and the date of photographing. The image of the data may be imprinted together with the endoscopic image.
As an auxiliary device for such data imprinting, there is a data imprinting device that is mainly used for presetting imprinting data.

Conventionally known data imprinting devices for endoscopic imaging include, for example, the one disclosed in Japanese Patent Application Laid-Open No. 59-78327 (Japanese Patent Application No. 188645-1983) filed by the present applicant. There is something written.

This device has a keyboard as an operation section, a memory, a display section, etc., and has a function of storing imprint data in advance and extracting the imprint data at the time of photographing and using it for imprinting. That is, when photographing an endoscopic image, the data can be copied by connecting a light source unit, an endoscope, a camera, etc. to this data imprinting device as necessary, and inputting data from the keyboard while displaying the data on the display. Presetting the imprint data in the memory in advance, displaying the imprint data preset in this memory or the imprint data entered from the keyboard at that time on the display for confirmation etc., and displaying the imprint data in the memory. This data imprinting device transfers the endoscopic image to a data imprinting display section in the camera for imprinting. Based on the imprint data transferred from the data imprint device, the camera displays the data on an imprint display section within the camera and imprints it onto the photographic film. The light source unit is connected to, for example, an endoscope, and not only supplies observation light to the endoscope, but also temporarily holds and transfers imprint data provided from the data imprint device to the camera. The endoscope has a portion that guides observation light from a light source unit into the body cavity, and a portion that inputs imprint data information provided from a data imprinting device via the light source unit to a camera. In addition, by directly connecting a camera to this data imprinting device and directly photographing the display section built into the data imprinting device, it is possible to record information such as the patient's name, medical record number, etc. among the above imprinted information. It is now possible to capture information common to a series of endoscopic images, etc., in a single frame of photographic film (separate from the endoscopic image). In this case, the photographing date, photographing site, etc. are mainly imprinted on the photographing frame of each endoscopic image.

Therefore, the data imprinting device described above can perform all its functions when the light source unit is connected, but when the light source unit is not connected, the data imprinting device cannot imprint onto the light source unit. Of course, it is not possible to transfer embedded data. It goes without saying that even if the data transfer is attempted without the light source unit being connected, it will not work properly. but,
In this case as well, key operations for this purpose are possible, and this may result in unnecessary key inputs or the data imprinting device itself may operate in vain to process the wasted key inputs. This results in a large loss of time and also causes the operator to misunderstand or operate incorrectly.

〔the purpose〕

An object of the present invention is to provide a data imprinting device for endoscope imaging that can prevent unnecessary operations corresponding to functions that do not match the connection state and always realize efficient operation according to the connection state. It's about doing.

〔overview〕

According to the present invention, it has multiple types of functions that can be used in combination with other devices, and at least some of which can be selectively realized depending on the combination state, and allows internal viewing of images of required data. A data imprinting device used for imprinting a mirror image on a photographic medium connects the other device to an operation unit having a plurality of function keys for specifying a function to be performed among a plurality of types of functions. a device determining means for determining whether another device is connected to this connecting portion, and a function that can be realized from among the plurality of functions according to the connection state of the device according to the determination result of this means. means for invalidating the designation by the operating unit when the function specified by the operating unit is a function other than the feasible function selected by the selecting unit; and a display means for displaying a function key for designating an achievable function selected by the selection means.

Furthermore, the data imprinting device 10 is imprinted with the endoscopic image of each imaging frame (each frame) of endoscopic imaging.
A frame data memory 64 in which frame data consisting of character data is stored. Normally, a maximum of 24 frames are imprinted separately from the endoscopic image on the first frame of the photographic film prior to endoscopic imaging of one patient. Patient data memory 66 in which character (=6 characters x 4 lines) patient data is stored, and camera 1
The patient data stored in the patient data memory 66 is configured using a dot matrix LCD (liquid crystal display) panel that can display 6 digits x 4 lines of characters and is provided opposite to the mount part to which the patient data 8 is connected. There is a built-in imprint display 68 that displays the data for photographing patient data.

Each part of the data imprinting device 10, that is, the keyboard 20, the external display 58, the memory number display 60, the frame data memory 64, the patient data memory 66, and the imprinting display 68 are mainly included in the data imprinting device 10. It is controlled by a central control unit consisting of a built-in microcomputer, etc.

In this data imprinting device 10, for data keyed in from the keyboard 20, data other than the memory number is displayed on the external display 58, and the memory number is displayed on the memory number display 60.
This display data is transferred to and stored in the frame data memory 64 or patient data memory 66 by operating the keyboard 20. The data in the patient data memory 66 is also transferred to the imprint display 68 and displayed by key operations on the keyboard 20. The display contents of the imprint display 68 can be imprinted on one frame of photographic film by connecting the camera 18 to the mount section.

Data in frame data memory 64 and patient data memory 66 can also be displayed on external display 58 by key operations on keyboard 20.

The light source unit 12 has three buffers: an alphanumeric buffer 72, a year/month/date buffer 74, and an hour/minute/second buffer 76 in addition to the original configuration of a light source unit such as a light source lamp (not shown). These buffers 72, 74 and 76 are connected to a display buffer that holds the data being displayed on the external display 58 of the imprinting device 10, and have "alphanumeric", "year, month, day" and "hour, minute, and second" keys, respectively. 48,50

The release of the camera for photographing the endoscopic image is controlled by a foot switch 78 connected to the light source unit 12 and a "release" key 56 on the keyboard 20.
Alternatively, the release switch of the camera 18 itself can be used. Note that when the camera 18 is coupled to the mount portion of the imprinting device 10, only the release switch of the camera 18 itself is effective. As mentioned above, the light source unit includes the original structure of the light source unit, such as a light source lamp, but since it is not directly related to the gist of the present invention, a detailed explanation thereof will be omitted.

Buffers 72, 74, 76 of light source unit 12
One of the retained data is selected by key operation on the keyboard 20, and the camera 18
The data is transferred to the display buffer 80 inside. The imprint display 82 inside the camera is composed of a 6-digit segment display LED similar to the external display 58, and when the camera 18 is released, data from the display buffer 80 connected to it is displayed. and is imprinted on photographic film.

In this system, when photographing a single patient, only patient data such as the patient's name, date of photographing, and medical record number are imprinted on the first frame of the photographic film. This patient data is normally stored in the patient data memory 66 in advance. In addition, frame data such as an imaged region is imprinted on each imaging frame along with an endoscopic image inside the body cavity. This frame data is normally stored in the frame data memory 64 in advance.

Storage of each of these data is performed as follows.

The patient data memory has memory areas for 30 patients from 01 to 30, and each area has a memory number key 40.
Specified by Each of these areas is divided into subareas for four lines, and each subarea is specified by a line designation key 36. “Patient” key 4
4. By operating the memory number key 40 and line specification key 36, data is transferred between the display buffer of the external display 58 and each subarea of the patient data memory 66 (external display section 58 → patient data memory 6).
6 or patient data memory 66 → external display 5
8) is performed. Similarly, the frame data memory 64 has 20 memory areas numbered 31 to 50, and each area is designated by the memory number key 40. Then, "data" key 46, memory number key 40
By the operation, data is transferred between the display buffer of the external display 58 and each area of the frame data memory 64 (external display 58 → frame data memory 64 or frame data memory 64 →
External display 58) is performed.

When photographing, for the first frame, the camera 18 is coupled to the mount portion of the imprinting device 10 as shown by the broken line in FIG. And "patient"
When the key 44 and memory number key 40 are pressed, the designated patient data is displayed on the imprint display 68. In this state, the camera 18 takes a picture. At this time, one line of patient data is displayed on the external display 58 for confirmation.

After the patient data has been captured, the endoscope body 1
6 is inserted into the patient's body cavity, and imaging of the endoscopic image inside the body cavity is started. At this time, the camera 18 is coupled to the eyepiece portion of the endoscope body 16 as shown by the solid line in FIG. Then, when the "data" key 46 and the memory number key 40 are pressed, the designated frame data is displayed on the external display 58. Furthermore, by pressing any of the keys for "alphanumeric characters,""year, month, day," or "hour, minute, and second," the external display 58
The data displayed is transferred to the buffers 72, 74, and 76 of the light source unit 12 and the display buffer 80 of the camera 18, displayed on the imprint display 82, and displayed in each photographic frame together with the endoscopic image inside the body cavity. be included. Here, it is possible to change the data displayed on the external display 58 while displaying it, but the details thereof are not directly related to the gist of the present invention, so the explanation will be omitted.

Next, connection state determination and corresponding control processing, which are essential parts of the present invention, will be explained in detail.

This processing is mainly performed as part of the system control operation by the central control unit built into the imprinting apparatus 10, and is usually performed as part of, for example, control processing software. The details of this process will be explained with reference to the flowchart shown in FIG.

First, when the power is turned on, the imprinting unit 10 connects the connection connector (not shown in FIG. 1 as it has a general configuration) before starting other processing.
A signal indicating that the data imprinting device 10 is connected is sent to the connection unit, ie, the light source unit 12 in this case, through the connection unit. Then, when the light source unit 12 is connected, light source information that is generated only when the light source unit 12 is connected is returned from the light source unit 12, such as information indicating the type of light source. When this light source information is returned, it is clear that the light source unit 12 is connected, and the light source unit 12
is determined to be connected. If it is determined that the light source unit 12 is connected, alphanumeric characters are transferred (function A), year, month and date are transferred (function B),
All functions including hours, minutes and seconds (Function C), stopwatch function (Function D), LCD display on the imprint display 68 (Function E), and panel display on the external display 58 and memory number display 60 (Function F). is possible, so each key 48, 5 for "alphanumeric characters", "year, month, day", "hour, minute, second", and "stop watch"
Display lamp 4 corresponding to 0, 52, 54 respectively
8a, 50a, 52a, and 54a are turned on, and at the same time, the imprint display 68, external display 58, and memory number display 60 are brought into a display state. In this state, all the above-mentioned functions of the data imprinting device 10 can be performed normally.

On the other hand, if the light source unit 12 is not connected to the data imprinting device 10, since there is no light source information input from the connected unit, it is determined that the connected unit is not connected, and each of the functions A
It corresponds only to functions D to F that can be executed even if the light source unit 12 is not connected.
8. External display 58 and memory number display 60
is displayed. Therefore, the display lamps 48a, 50a, 52a corresponding to the "alphanumeric,""year, month, day," and "hour, minute, and second" keys 48, 50, and 52 are not lit. At the same time, from now on, each of these keys 48, 5
Each function corresponding to the operation of keys 48, 50, and 52 is prohibited on the software, and an alarm (not shown) sounds when each of these keys 48, 50, and 52 is operated, indicating that an inappropriate operation has been performed. to warn you. Therefore, in this case, the camera 18 is coupled to the mount portion of the imprinting device 10 to photograph the patient data and the patient data memory 66,
Only data can be preset into the frame data memory 64.

In this way, when the connected unit is not connected, only the functions that correspond to the functions that can be performed are enabled, and accordingly, the display clearly indicates which function keys correspond to valid function keys and which function keys do not. Since the functions are distinguished from each other, there is little risk of accidentally attempting to perform an impossible function. Additionally, even if you perform an operation that requests an inappropriate function, an alarm will alert you to the fact that the operation is inappropriate, and furthermore, such an operation will be invalidated as processing is prohibited. .

The above-mentioned stopwatch function means to measure time like a stopwatch using a clock device built into the data imprinting device, or to internally view the clock data via the alphanumeric buffer 72 of the light source unit 12. This function imprints a mirror image on each photographed frame. Display lamps 44a, 46a, 5 corresponding to the "patient", "data", and "release" keys 44, 46, 56, respectively
6a lights up when each of these keys 44, 46, and 56 becomes operable, indicating that the operation is valid.

The present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with various modifications without changing the gist thereof.

For example, in the above-described embodiment, for a function that is not enabled according to the determination of the connection state, the indicator lamp is not lit, an alarm is displayed, and the process corresponding to that function is prohibited. Only a part of these may be implemented, or validation/invalidation other than those described above may be executed.

Furthermore, even when using an auxiliary device other than the light source unit as the connection unit, only the functions that can be performed in the connected state may be enabled in the same way as described above.

Furthermore, the connection state of the connected unit may be determined by a method other than the above, that is, the connection state may be determined simply based on a hardware response or a characteristic of the connection state determined by hardware.

〔Effect of the invention〕

According to the present invention, it is possible to provide a data imprinting device for endoscopy that can prevent unnecessary operations corresponding to functions that do not match the connection state and can always realize efficient operations according to the connection state. can.
