Abstract

PURPOSE:To accurately detect the use time of an individual probe, by measuring an actually outputted output time by a count means to store the same at every probe. CONSTITUTION:When a desired output level is set by an output setting switch 13 and a foot switch 14 is stepped, a CPU 17 applies count start output to a counter 20 and operates a beam shutter 21 to output laser beam from a laser probe 10 while the counter 20 continues to count laser output. When the foot switch 14 is opened, the counting operation of the counter 20 is stopped and the count of the counter 20 is read to be recorded on an RAM 19 but, in the case of the already registered probe, the discrimination data of the mounted probe is read from the RAM 19 and this new count is added to the numerical record. The sum is written in the RAM 19 as a total use time and, at the time of a newly registered probe, the count is recorded on the address after probe discrimination data C as a use time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a treatment device, and particularly to a treatment device that destroys stones using shock waves of electrical discharge or operates on affected areas using a laser beam.

[Prior Art] As treatment devices, there are known electric discharge stone destruction devices that destroy stones using shock waves of electric discharge, and laser treatment devices that cauterize the affected area by irradiating the affected area with a laser beam.

The discharge calculus destruction device is configured to apply a high voltage to the electrodes of a probe to generate a discharge between the electrodes, and destroy the calculus with the shock wave of this discharge. According to such a calculus destruction device, the electrode of the probe is consumed by the discharge, and as the number of discharges increases, the discharge becomes weaker, and eventually no discharge occurs. To this end, the probe is replaced with a new probe after it has been used for a predetermined period of time. In order to know when to replace the probe, the calculus destruction device is provided with means for detecting the life of the probe.

Further, in a laser treatment device, the laser probe is deteriorated due to the output of laser through the laser probe, and the laser probe needs to be replaced. For this purpose, means for detecting the lifetime of the laser probe is provided.

The conventional detection means has a structure that counts the number of outputs of the probe or the number of times the probe is used, and prohibits the use of the probe when this number reaches a value corresponding to the lifespan.

[Problems to be Solved by the Invention] According to the above-mentioned conventional lifespan detection device, if the probe is replaced with another type during use, the usage time of the probe that was in use becomes unknown.

Additionally, there is a device that blows out the fuse in order to prevent the reuse of probes that have reached the end of their service life, but even with such devices, the service life is determined by the number of times the probe is discharged or used. Since the time the probe is used for a short discharge time is not measured, even if the probe is fully usable, it will become unusable once the number of uses or the number of discharges reaches the lifetime value.

Arranging fuses in a matrix has been devised to improve the accuracy of measuring the number of outputs or number of uses, but such a configuration requires a large number of fuses, which hinders miniaturization of the probe.

Therefore, an object of the present invention is to provide a treatment device that can accurately detect the usage time of each probe even if a plurality of probes are used interchangeably.

[Means for Solving the Problems] According to the present invention, as shown in FIG. means (2), means (3) for outputting therapeutic energy through the probe, means (5) for counting the time for outputting therapeutic energy through the probe, and means (6) for storing the output time for each probe.
) and a control means (4) for controlling each means.

[The output time actually outputted from the output means is measured by the counting means, and the measured value is stored in the storage means for each probe. The usage time of each probe can be accurately detected by the information stored in this storage means.

[Example] According to the treatment apparatus shown in FIG. 2, for example, an identification barcode 11 for identifying the probe is provided on the connector lOa of the probe 10 that outputs a laser beam. Probe connector log is socket 1 of laser output device 12
2a. The laser output device 12 is provided with an output setting switch 13 for setting the laser output and a foot switch 14 for turning the output on and off.

As shown in FIG. 3, a line sensor 15a and a light emitting element 15b for reading the identification barcode provided on the probe connector 10 are arranged in the laser output device 12 so as to face the probe connector IOa.

As shown in FIG. 4, the line sensor 15a is connected to the I10 circuit 1.
It is coupled to the CPU 17 via B. CPU17 is RO
Connected to M 1B and RAM I'l. ROMU
A program is stored in RAM 18, and information regarding the probe to be used is stored in RAM 19 as shown in FIG.

The I10 circuit 1B transmits the outputs of the output setting switch 13 and foot switch 14 to the CPU 17. The CPU 17 outputs an operation signal to the counter 20 and the beam shutter 21 in response to the operation of the foot switch 14.
Counter 20 and beam shutter 21 via circuit 16
connected to. A counter 20 measures the operating time in response to the operation of the foot switch 14, and a beam shutter 21 is provided to open and close the output of the laser in response to the operation of the foot switch 20.

In the above device, when the connector lOa of the probe lO is connected to the socket 12a of the laser output device 12, the light from the light emitting cord 15b illuminates the barcode 11, and the reflected light enters the line sensor 15a. Line sensor 15a outputs a signal corresponding to barcode 11.

The output signal of the line sensor 15a is L/Q circuit 16
When input to CPU 17 via
7 compares the human power information with the probe information stored in the RAM 19 and determines whether the input information, that is, the identification information of the attached probe IO is registered in the table of the RAM 19 shown in FIG. Check whether or not. If the input identification information is not registered in the table of FIG. 5, the CPU 17 searches for the end of the recorded area of the RAM 19, that is, address +3 in FIG. Clear the next recording area, that is, the recording area at address 14. The identification information of the attached probe, for example C, is recorded in the cleared recording area. After this, the seventh
Proceed to the flow in the diagram. Also, if the attached probe has already been registered during the registration check, the seventh
Proceed to the flow in the diagram.

In the flow of Fig. 7, first, output setting switch 1
3 sets the desired output level.

At this time, when the foot switch 14 is stepped on, the CPU 1
7 starts a count start output to the counter 20 and operates the beam shutter 21. By operating the beam shutter, a laser beam is output from the laser probe IO. While the foot switch 14 is depressed, the laser continues to be output and the counter 20 continues to count the laser output.

When the foot switch 14 is opened, the CPU 17 closes the beam shutter 21, stops the laser output, and stops the counting operation of the counter 20. The count value of the counter 20 at this time is read out and recorded in the RAM 19, but if the probe is already registered, the usage time corresponding to the identification information of the attached probe, e.g. (corresponding to the count value) is RAM
19, and the currently counted count value is added to this recorded value. The additional value is RA as the total usage time
Written to M19. When the probe is newly registered, a count value is recorded at the address after the probe identification information C as the usage time.

Usage time/l each time the probe is used as above
are determined, sequentially added, and stored. This added value is compared with the value corresponding to the probe life, and when it becomes the life value,
Action is taken to prohibit the use of that probe. In addition to generating an alarm sound or displaying a warning, this prohibition may include means for actively prohibiting output of the laser beam, such as closing a beam shutter.

In the above embodiment, a RAM for recording probe information
can be constructed from a battery-backed C-MOSRAM or an electrically writable and erasable EFROM. Further, a circuit combining a DIP switch or a resistor may be used as the probe identification means.Furthermore, instead of counting the usage time with a counter, the usage time can be counted inside the CPU.

Although the above embodiment has been described as a laser treatment device, the present invention can be applied to an electric discharge stone destruction device.

In this case, there is a need to limit the maximum output that can be used due to probe tolerance issues, so by identifying the probe, the output can be automatically limited.

[Effect] The usage time of each probe is measured and recorded individually, so the usage time of each probe can be accurately known.
The probe can be used to its maximum capacity.
