Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention newly registers an electronic endoscope in an electronic endoscope database in which data such as characteristic values and management information of the electronic endoscope are recorded for each electronic endoscope. Electronic endoscope registration method of database for endoscope, and
The present invention relates to a database system for electronic endoscopes that manages a database for electronic endoscopes.

[0002]

2. Description of the Related Art An electronic endoscope having a solid-state image sensor such as a CCD at its tip generally processes an electric signal from the solid-state image sensor and outputs it to an output means such as a monitor or a video printer. It is used together with a processor.

The electronic endoscope is detachably connected to the endoscope processor. In addition, the endoscope processor is usually connectable to multiple types of electronic endoscopes, and therefore,
Even if multiple types of electronic endoscopes are used, the number of endoscope processors can be increased by connecting and using an electronic endoscope suitable for the site to be observed / treated appropriately. Needs only one.

In general, an electronic endoscope has a storage element such as an EEPROM. The storage element stores the type of electronic endoscope, serial number, white balance value, and the like. When the electronic endoscope is connected to the endoscope processor, the endoscope processor reads various data stored in the storage element, displays the type of the electronic endoscope on the monitor, and displays the white balance. It is set to a value suitable for electronic endoscopes.

Since the video signals for monitor output, which are generated by the endoscope processors, vary slightly among the endoscope processors, the white balance value in the endoscope stored in the storage element. If is set as is, the white balance may shift slightly. Therefore, in order to avoid manually resetting the white balance value each time the electronic endoscope is attached to the endoscope processor, the endoscope processor sets the electronic endoscope type and serial number once set. It is necessary to store the white balance value for each. That is, when the electronic endoscope is reconnected, the white balance value stored in the endoscope processor is used. When the white balance value is automatically reset in this way, the endoscope processor has a kind of database that refers to an appropriate white balance value based on the type and serial number of the electronic endoscope.

Further, the endoscope processor counts the number of times the electronic endoscope is attached to the endoscope processor to determine the frequency of use of the electronic endoscope used in the endoscope processor. can do. This frequency of use
For example, it can be used for maintenance of an endoscope.

In such an endoscope processor,
A new electronic endoscope cannot be registered in a state where the electronic endoscope is registered in the database up to the full storage capacity. Therefore, conventionally, a new electronic endoscope has been registered after manually deleting unnecessary electronic endoscope data.

[0008]

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides an electronic endoscope database that allows an electronic endoscope to be registered in an endoscope processor more easily and quickly. An object is to provide an endoscope registration method and a database system for an electronic endoscope.

[0009]

In order to solve the above problems, in the electronic endoscope registration method of the database for electronic endoscopes of the present invention, the number of electronic endoscopes registered in the database is set to a predetermined number. If the number of electronic endoscopes registered in the database has reached a predetermined number, the counting step to determine whether or not it has been reached, and the data related to the predetermined electronic endoscope among the electronic endoscopes registered in the database When the number of electronic endoscopes registered in the database has reached a predetermined number, there is a deregistration step of deregistering the electronic endoscope and a recording step of recording the data of the electronic endoscope newly registered in the database. In the recording step, the data of the electronic endoscope to be newly registered is recorded in the storage area on the database that was deregistered in the deregistration step.

Therefore, when a new electronic endoscope is registered in the database, even if the electronic endoscope has been registered in the database up to the storage capacity, unnecessary electronic endoscope data can be manually deleted. A new electronic endoscope is automatically registered without the need to do so.

Here, the data regarding the predetermined electronic endoscope may be data regarding the first registered electronic endoscope among the electronic endoscopes registered in the database.

With such a structure, when a new electronic endoscope is registered in the database, if the electronic endoscope is registered in the database up to the full storage capacity, the electronic endoscope with the oldest registration date and time is registered. The data about the endoscope is automatically deregistered.

Similarly, the data relating to the predetermined electronic endoscope may be data relating to the electronic endoscope registered in the database and having the earliest date and time of last use.

With this configuration, when a new electronic endoscope is registered in the database, if the electronic endoscope is registered in the database up to the full storage capacity, the most unused electronic endoscope will be used. The data about the endoscope is automatically deregistered.

It should be noted that the electronic endoscope database system for managing the database has an endoscope insertion / extraction detecting means for determining whether or not the electronic endoscope is connected to the endoscope processor, and the updating means is When the electronic endoscope is continuously connected to the endoscope processor, the time at that time may be recorded in the database as the date and time when the electronic endoscope was last used.

With such a structure, even if an unnecessary electronic endoscope (which may be deleted from the database) is mounted on the endoscope processor, it is possible to set the electronic endoscope within a predetermined time. If the electronic endoscope is removed from the endoscope processor, the “last used date and time” of the electronic endoscope in the database is not updated.

The electronic endoscope database system for managing the database may be incorporated in the endoscope processor.
