Description

  The present invention relates to an endoscope system, and more specifically, detects a notification result of a high-frequency ablation device having a notification means for notifying an operation state, and automatically controls a smoke exhausting operation by an insufflation apparatus based on the detection result. The present invention relates to an endoscope system that can be used.

  In order to reduce the invasion to a patient, a laparoscopic surgical operation (hereinafter, also referred to as a surgical operation) for performing a therapeutic procedure without performing a laparotomy is performed. In this surgical operation, for example, a first trocar for guiding an endoscope for observation into a body cavity and a second trocar for guiding a treatment tool to a treatment site are punctured in the abdomen of the patient. Then, for the purpose of securing the field of view of the endoscope and the region for operating the treatment instrument via the trocar or another trocar, the gas for pneumoconiosis is placed in the abdominal cavity by the pneumoperitoneum. Is injected.

  By injecting the gas for pneumoperitoneum into the abdominal cavity, the abdominal cavity becomes inflated. Then, with the endoscope inserted into the abdominal cavity through the first trocar, a treatment or the like can be performed while observing the treatment site and confirming the treatment tool inserted through the second trocar. .

  For example, carbon dioxide gas (hereinafter referred to as carbon dioxide gas) that is easily absorbed by a living body is used as the gas for insufflation.

  In such an endoscope system, when performing a procedure under endoscopic observation, a treatment site in the abdominal cavity that is expanded by injecting gas for a pneumoperitoneum is treated with an ablation device (electric scalpel) such as a high-frequency ablation device or a laser device. In some cases, smoke generated by the ablation device fills the abdominal cavity and obstructs the viewing field of the endoscope.

  Therefore, in such a case, conventionally, after the drive of the cautery device is temporarily stopped, the endoscope or treatment tool introduced into the abdominal cavity through the inner hole of the trocar or another trocar is removed from the trocar, While supplying carbon dioxide gas into the abdominal cavity by the insufflation apparatus, the smoke filling the abdominal cavity is naturally discharged to the outside through the inner hole of the trocar communicating with the abdominal cavity.

Further, conventionally, many proposals have been made to actively suck the smoke filled in the abdominal cavity by using the suction (smoke exhaust) means of the pneumoperitoneum apparatus to perform the smoke exhaust operation of the abdominal cavity. Yes.
For example, as disclosed in Japanese Patent No. 2544880, the cautery device and the insufflation device are electrically connected to enable bidirectional communication and are synchronized with the output (cauterization) signal of the cautery device. In addition, there is a smoke removal system for an insufflation device that removes smoke filled in the abdominal cavity from the body by operating the suction (smoke exhaust) means of the insufflation device.

As another conventional example, for example, as disclosed in Japanese Patent Application Laid-Open No. 11-309156, a system controller that controls a surgical system is electrically connected to the insufflation apparatus, and at the tip of the trocar. A concentration measuring device for detecting the concentration of smoke in the abdominal cavity is provided, and based on the concentration information from the concentration measuring device, the system controller controls the exhaust operation by the pneumoconitory device according to the operating state of the ablation device. There is a smoke device.
Japanese Patent No. 2544880, JP-A-11-309156

  However, in the conventional example of the Japanese Patent No. 2544880, the ablation device must have a communication function for communicating with the pneumoperitoneum, and an existing ablation device that does not have a communication function, Alternatively, there is a problem in that the smoke exhausting operation cannot be automatically performed by the insufflation apparatus using the cautery apparatus having a different communication protocol.

  In the prior art disclosed in Japanese Patent Laid-Open No. 11-309156, the trocar is provided with the concentration measuring device, which is expensive. For this reason, an endoscope system that can automatically perform the smoke exhausting operation by the pneumoperitoneum at low cost is desired.

  Therefore, the present invention has been made in view of the above circumstances, and even when a cautery device that does not have a communication function is used, the smoke exhausting operation by the insufflation device is automatically controlled with a simple configuration and at a low cost. An object of the present invention is to provide an endoscope system that can be used.

  The endoscope system according to the present invention is an endoscope system capable of performing a plurality of procedures, and includes a plurality of medical devices including a medical device having a notification unit that notifies an operation state, and a medical device having the notification unit. A detection unit capable of detecting a notification result by the notification unit in a separated state; and an identification unit capable of identifying an operation state of a medical device having the notification unit based on a detection result of the detection unit. It is characterized by this.

  According to the present invention, even when a cautery device that does not have a communication function is used, it is possible to realize an endoscope system that can automatically control the smoke exhausting operation by the insufflation device with a simple configuration and at a low cost.

In the present embodiment, as described above, the electric knife 8 does not have a communication function. For this reason, the electric knife 8 is not electrically connected to the system controller 15 and is separated.
In addition, the electric knife 8 has an output sound reproduction unit which is a notification means for generating an output sound (sound or other sound) for notifying the operator of the operation state. The sound level generated by the output sound reproduction unit is reproduced at a level based on medical standards.

  A speaker (not shown) which is the output sound reproducing unit is provided on the back side inside the electric knife 8. A plurality of holes 8a for effectively transmitting output sound from the speaker (not shown) to the outside are provided on the back surface of the electric knife 8 corresponding to the speaker (not shown).

  In the present embodiment, as shown in FIG. 3, a microphone 18 serving as detection means is detachably attached to, for example, a mounting portion 18a at a predetermined position where a plurality of holes 8a on the back side of the electric knife 8 are provided. It is like that. For example, a magnet is used as the mounting portion 18a.

  In addition, the attaching part 18a should just be what can attach the microphone 18 to the back surface of the electric knife 8 detachably not only in a magnet.

  The microphone 18 is configured using, for example, a condenser microphone. The mounting portion 18a is provided on the distal end side, and a connection cable 18a for electrically connecting to the waveform recognition circuit 46 is provided on the proximal end side. It is extended.

Next, the configuration of the waveform recognition circuit 46 which is a recognition means in the system controller 15 will be described with reference to FIG.
As shown in FIG. 4, the waveform recognition circuit 46 includes a band-pass filter (BPF) 46a electrically connected to the connection cable 18a extending from the microphone 18, and an output signal of the band filter 46a. And a comparator 52 for inputting the output signal of the rectification / integration circuit 51.

  The output sound signal from the microphone 18 is supplied to the band filter 46a of the waveform recognition circuit 46 through the connection cable 18a. The output sound signal from the microphone 18 supplied to the band filter 46a is an analog signal waveform as shown in FIG.

  The band filter 46 a passes only a band component within a predetermined range of the input output sound signal and outputs the band component to the rectification / integration circuit 51.

  The rectification / integration circuit 51 rectifies the output sound signal from the bandpass filter 46 a, performs the integration process on the rectified output sound signal, and outputs it to the comparator 52.

  A rectified waveform of the output sound signal rectified by the rectifying / integrating circuit 51 is shown in FIG. 6, and an output waveform after the integration processing to be output to the comparator 52 is shown in FIG.

  The comparator 52 compares the output signal value from the rectification / integration circuit 51 with a preset threshold value VL and outputs the comparison result to the CPU 45 which is a control means.

  In this case, as shown in FIG. 7, for example, when the output signal value from the rectifying / integrating circuit 51 is smaller than the threshold value VL, the comparator 52 outputs a “low” signal, and conversely, Outputs a “High” signal.

  In this case, since the time constant is set by the rectification / integration circuit 51 and the threshold value VL, simple operation sounds such as “beep” and “buzz” are not detected, and the electric knife 8 such as “beep” is being output. It is possible to detect only the continuous output sound that continues to sound in conjunction with.

  The threshold value VL can be freely changed using, for example, the centralized operation panel 14, and the time constant can be freely adjusted in order to detect only the output sound according to the type and model of the electric knife 8. is there.

  The CPU 45 determines whether the electric knife 8 is in an output state or a non-output state based on the comparison result by the comparator 52, and controls the smoke exhausting operation of the insufflation apparatus 9 based on the determination result.

  For example, when the comparison result by the comparator 52 is a low level signal, the CPU 45 determines that the electric knife 8 is in a non-output state and does not perform the smoke exhausting operation of the pneumoperitoneum 9, but conversely the high level. If it is a signal, it is determined that the electric knife 8 is in the output state, and control is performed so as to drive the smoke exhausting operation of the insufflator 9.

A flowchart showing an example of such a control example is shown in FIG.
Next, the control operation of the endoscope system of the present embodiment will be described with reference to FIG.

  In the endoscope system of this example, when the power is turned on, the CPU 45 of the system controller 15 reads and starts the program shown in FIG. 8 stored in an internal memory (not shown).

  As shown in FIG. 8, the CPU 45 captures the output sound signal into the waveform recognition circuit 46 in the system controller 15 by the microphone 18 attached to the back surface of the electric knife 8 by the process of step S <b> 1.

  In this case, the output sound signal from the microphone 18 (see FIG. 5) is output to the rectification / integration circuit 51 through the band filter 46a through only the band component in the predetermined range of the output sound signal.

  Then, the CPU 45 performs control so that the output signal of the bandpass filter 46a is subjected to rectification processing and integration processing by the rectification / integration circuit 51 in the processing of the subsequent step S2. Thus, the waveform of the output signal of the rectifying / integrating circuit 51 is as shown in FIG.

Then, the CPU 45 causes the comparator 52 to compare the output signal value from the rectification / integration circuit 51 with a preset threshold value VL by the processing of the subsequent step S3.
In this case, as shown in FIG. 7, for example, when the output signal value from the rectifying / integrating circuit 51 is smaller than the threshold value VL, the comparator 52 outputs a “low” signal, and conversely, Outputs a “High” signal.

  Next, the CPU 45 determines whether or not the output signal, which is the comparison result by the comparator 52, is a “high level” signal in the determination process of step S4, and determines “high level”. If it is, the process proceeds to step S6. Conversely, if not (if it is a "Low" signal), the process proceeds to step S5.

  In the process of step S5, since the output signal as a comparison result by the comparator 52 is not a “High” signal, the CPU 45 determines that the electric knife 8 is in the non-output state, and the pneumoperitoneum 9 Control so as not to drive the smoke exhausting operation.

  On the other hand, in the process of step S6, since the output signal as a comparison result by the comparator 52 is a signal of “High”, the CPU 45 determines that the electric knife 8 is in the output state, and is insulted. Control is performed to drive the smoke exhausting operation by the device 9.

  In this case, the CPU 45 recognizes that the electric knife 8 is in an output state continuously for a preset time using the time information from the timer provided therein, and then discharges by the pneumoperitoneum 9. You may control to drive smoke operation. Thereby, the output state of the electric knife 8 can be reliably detected. Of course, the set time can be arbitrarily set.

  Therefore, according to the present embodiment, by performing the above-described control, even when the cautery device 8 having no communication function is used, the smoke exhausting operation by the insufflation device 9 is automatically performed with a simple configuration and at a low cost. It becomes possible to control to. As a result, a clear visual field can always be secured in the abdominal cavity.

  In addition, since the output of the electric knife 8 can be detected without electrical connection with the electric knife 8, it is not affected by the noise of the electric knife 8, and is electrically separated from the electric knife 8. As a result, it is possible to easily ensure the electrical safety, shorten the development period, reduce the development cost, and reduce the cost.

  In addition, since it is not necessary to correspond to communication control, a communication program corresponding to the electric knife 8 or a design or part of the communication part is unnecessary, shortening the development period, reducing the development cost, and reducing the cost. Can be achieved.

  Furthermore, since it is not necessary to cope with communication control, even a new type of high-frequency cautery device can be dealt with immediately.

  In the present embodiment, the operating state of the electric knife 8 is identified based on the output sound signal from the microphone 18, but the present invention is not limited to this. For example, the electric knife 8 is attached to the mounting portion 18a of the microphone 18. It is also possible to provide a light receiving means for receiving the light emitted from the LED that is lit at the time of output, and to identify the operating state of the electric knife 8 based on the presence or absence of the light received by the light receiving means. Also in this case, the same operation and effect as the first embodiment can be obtained.

FIG. 11 is a diagram illustrating a registered waveform for each, FIG. 11 is an explanatory diagram when a comparison waveform input operation of an output sound signal of a high-frequency cautery device is performed by a centralized operation panel, and FIG. 12 is an output sound detected by the comparison waveform input operation of FIG.

FIG. 15 is a flowchart showing an example of operation control of the insufflation apparatus by the CPU of FIG. 9.

  The endoscope system of the present embodiment is further configured to be able to detect the operating state of the electric knife 8 with high accuracy, and the description of the same components as those of the first embodiment is omitted, and only different portions are described. Will be explained.

  The overall configuration of the endoscope system according to the present embodiment is substantially the same as that of the endoscope surgical operation system 1 according to the first embodiment. A system controller 15 used in the endoscope surgical operation system 1 is shown in FIG. A waveform recognition circuit 46A is provided.

  As shown in FIG. 9, the waveform recognition circuit 46A includes a band filter 46a, an A / D converter 61, a waveform memory 62, and a registered waveform memory 63.

  The output sound signal (see FIG. 5) from the microphone 18 is output to the A / D converter 61 through only a band component within a predetermined range of the output sound signal by the band filter 46a.

The A / D converter 61 digitizes the supplied analog output sound signal, converts it into digital output sound data, and outputs it to the waveform memory 62.
In this case, the A / D converter 61 outputs the digital output sound waveform data at every predetermined sampling frequency (sampling time). The CPU 45 measures the sampling time by the A / D converter 61 using an internal timer counter (not shown).

  The waveform memory 62 is a memory of a shift register or ring buffer type, and is a memory that additionally stores the latest data while deleting the oldest data, and the data is stored in time series. The memory capacity is a memory having a capacity of one cycle or more of the output waveform.

  The waveform memory 62 additionally stores the output sound waveform data from the A / D converter 61 for each sampling time of the A / D converter 61, and gives the stored output sound waveform data to the CPU 45 at the time of reading. . Note that the reading of the output sound waveform data from the waveform memory 62 is controlled by the CPU 45.

The registered waveform memory 63 stores output sound waveform data 63a to 63c of one cycle (one cycle) for each model 8A to 8C of the electric knife 8.
For example, the registered waveform memory 63 includes output sound waveform data 63a based on the model name 8A (UES-20), output sound waveform data 63b based on the model name 8B (UES-30), and model name 8C (PSD-30). ) Based on output sound waveform data 63c. Note that the present invention is not limited to this, and output sound waveform data of other different models may be registered.

  Each registered waveform data for each model stored in the registered waveform memory 63 is read out by reading control by the CPU 45.

  The endoscope system of the present embodiment can register output sound waveform data of any model in the registered waveform memory 63.

  FIG. 11 shows a comparison waveform registration screen 14A for performing a comparison waveform input operation in the predetermined electric knife 8 in this case.

  As shown in FIG. 11, when the mode execution indicating the comparison waveform registration is operated by the centralized operation panel 14 or the like, the CPU 45 displays the comparative waveform registration screen 14 </ b> A on the centralized operation panel 14.

  The comparison waveform registration screen 14A includes output sound waveform data (A / D converter output sound waveform data) 61a from the waveform memory 62 and a start point slide bar 50 that indicates the start point of one cycle of the output sound waveform data 61a. And an end point slide bar 50A for instructing the end point, a start point operation button 14a for adjusting the start point slide bar 50 in the phase direction of the waveform, and an end point operation button for adjusting the end point slide bar 50A in the phase direction of the waveform. 14b, and a registration button 50B for registering the output sound waveform data 61a in a state where one cycle is set by the start point operation button 14a and the end point operation button 14b.

  With this configuration, the waveform registration of one cycle (one cycle) of the output sound waveform data 53 in the electric knife 8 of any model is performed by appropriately operating the comparison waveform registration screen 14A provided on the centralized operation panel 14. It can be performed.

  Other configurations are substantially the same as those of the first embodiment.

  Next, the control operation by the CPU 45 in the endoscope system of the present embodiment will be described with reference to FIGS.

  In the endoscope system of this example, when the power is turned on, the CPU 45 of the system controller 15 reads and starts the program shown in FIG. 15 stored in an internal memory (not shown).

  As shown in FIG. 15, the output sound signal is taken into the waveform recognition circuit 46 </ b> A in the system controller 15 by the microphone 18 attached to the back surface of the electric knife 8 by the process of step S <b> 1.

  In this case, the output sound signal from the microphone 18 (see FIG. 5) is output to the A / D converter 61 through only the band component within the predetermined range of the output sound signal by the band filter 46a.

  Then, in the subsequent step S10, the CPU 45 converts the output signal of the bandpass filter 46a into digital output sound waveform data by A / D converter 61 for each predetermined sampling frequency (sampling time S1). And output to the waveform memory 62.

  In the subsequent step S11, the waveform memory 62 updates and stores the output sound waveform data from the A / D converter 61. In the process of step S11, the output sound waveform data is supplied to the waveform memory 62 every sampling time S1 of the A / D converter 61. Therefore, among the output sound waveform data stored in the waveform memory 62, The oldest data is deleted, and the latest output sound waveform data supplied is additionally stored and updated.

  Next, the CPU 45 determines whether or not the number of samplings by the A / D converter 61 exceeds a predetermined number (predetermined sampling time) using an internal timer counter (not shown) by the determination process in step S12. If it is determined that the value has been exceeded, the process proceeds to step S13. If not, the process returns to step S1.

  That is, in the determination process of step S12, since the sampling time S1 by the A / D converter 61 is extremely short due to its characteristics, in order to reduce the load on the CPU 45, every sampling time S1, that is, Each time one data in the waveform memory 62 is updated, the comparison processing with the registered waveform (step S14) is not performed, and a predetermined sampling time (every S1 × n, n is an integer), that is, a predetermined in the waveform memory 62 This is a determination process for performing the comparison process (step S14) every time the number of data is updated. Of course, if the power of the CPU 45 is sufficient, the comparison process (step S14) may be performed every sampling time S1 without the determination process of step S12.

  In the process of step S13, in order to measure the predetermined time until the next comparison process (step S14), the sampling time measurement value of a timer counter (not shown) is reset, and the process proceeds to the determination process of step S14.

  In the determination process of step S14, the CPU 45 compares the output sound waveform data read from the waveform memory 62 with the registered sound waveform data read from the registered waveform memory 63, and if they match, the electric knife 8 is in the output state. The process proceeds to step S15, and if they do not match, the process proceeds to step S16.

  In addition to the timer for measuring the predetermined number of times of sampling, the CPU 45 measures a time corresponding to one cycle of the output sound waveform (also referred to as a single cycle time measurement value) by an internal timer counter.

  In the process of step S15, since the current output sound waveform data and the registered sound waveform data read from the registered waveform memory 63 match, the CPU 45 uses one of the timer counters (not shown). The cycle time measurement value is reset, and control is performed so that the smoke exhausting operation by the pneumoperitoneum 9 is driven by the processing of the subsequent step S5. Then, the process returns to step S1.

  On the other hand, in the determination process in step S16, it is determined in step S14 that the current output sound waveform data matches the registered sound waveform data read from the registered waveform memory 63, but the waveforms match with completely different waveforms. The waveform is the same as if not (the case is not the intended output sound waveform), but does not match because the phases to be compared are different (if the output sound waveform is intended, but the comparison part is misaligned and does not match) Therefore, in order to make a comparison in all phases of one cycle of the output sound waveform, the CPU 45 determines whether or not the one cycle time measurement value of the timer counter (not shown) is one cycle or more. To do.

  When the measured value of one cycle time is smaller than one cycle, the CPU 45 may be outputting the electric knife 8 only by comparing the phase shift. Without changing, the processing is returned to the step S1. When the one cycle time measurement value is larger than one cycle, the electric knife 8 determines that it is not outputting, and controls so as not to drive the smoke exhausting operation by the pneumoperitoneum device 9 by the processing of the subsequent step S6. Then, the process returns to step S1.

  FIG. 13 is an explanatory diagram for explaining the waveform comparison process by the determination process in step S14. FIG. 14 shows the pneumoperitoneum apparatus 9 controlled based on the processing results in steps S14, S15, and S16. It shows the smoke exhaust operation state.

  As shown in FIG. 13, in the determination process of step S14, for example, the registered sound waveform data registered in the registered waveform memory 63 is the output sound waveform data 53 of the model name (UES-20) 8A shown in FIG. Then, the CPU 45 is the waveform data read from the waveform memory 62 at time 1, time 2 after a predetermined sampling time, time 3, time 4... The output sound waveform data 61a of the A / D converter is compared with the output sound waveform data 53. That is, a comparison result for each predetermined sampling time is obtained.

  Therefore, by performing the processing of step S12 to step S16, as shown in FIG. 13 and FIG. 14, the waveform comparison is inconsistent at time 1 and more than one cycle time measurement, and at time 2, the waveform comparison is inconsistent and has one cycle time. At time 3 or more, at time 3, the waveform comparison is inconsistent and a comparison result that is more than one cycle time measurement is obtained, and at time 4, the comparison result that the waveform is matched for the first time is obtained. The period measurement value is also reset. Thus, during the time 1 to time 3, the smoke exhausting operation of the insufflation apparatus 9 is not performed, and at time 4 the smoke exhausting operation of the insufflation apparatus 9 is driven.

  After that, since the output sound waveform data 53 is registered in one cycle, it does not coincide with time 5 to time 7, but since the one cycle time measurement value is less than one cycle, only the phase to be compared is shifted. Since there is a possibility that the electric knife 8 is outputting, the smoke exhausting operation of the insufflation apparatus 9 is not changed and the driving state is maintained as it is. Since there is a discrepancy at time n + 1 and there is more than one cycle, it can be determined that the output sound waveform is different from the output sound of the electric knife 8, and the smoke exhausting operation of the pneumoperitoneum 9 is stopped.

  Thereafter, the same determination process as described above is performed.

  Therefore, according to the present embodiment, by performing the control, in addition to the effect of the first embodiment, the output sound waveform is determined by comparing with the intended output sound waveform. A good output state of the electric knife 8 can be detected, and responsiveness can be improved as compared with the first embodiment.

  In this embodiment, the sampling frequency in the A / D converter 61 and the sampling frequency of the output sound waveform registered in the registered waveform memory 63 are set to be the same.

  16 to 21 relate to the third embodiment of the present invention, FIG. 16 is a block diagram showing a specific configuration of the waveform recognition circuit in the third embodiment, and FIG. 17 is a model pre-registered in the registered waveform memory of FIG. FIG. 18 is a diagram illustrating the frequency coefficient for each operation, FIG. 18 is an explanatory diagram when a comparison frequency coefficient input operation of the output sound signal of the high-frequency cautery device is performed by the centralized operation panel, and FIG. 19 is detected by the comparison frequency coefficient input operation of FIG. FIG. 20 is a graph showing the comparison frequency coefficient of the output sound signal, FIG. 20 is a graph showing the relationship between the output waveform of the A / D converter of FIG. 16 and the output frequency count of the DFFT of FIG. 16, and FIG. It is a flowchart which shows the example of operation control of an apparatus.

  The endoscope system of the present embodiment is configured to be able to detect the output state of the electric knife 8 with higher accuracy than the first embodiment, and the same components as those of the first and second embodiments. Description of is omitted, and only different parts are described.

  The overall configuration of the endoscope system according to the present embodiment is substantially the same as that of the endoscope surgical operation system 1 according to the first embodiment. A system controller 15 used in the endoscope surgical operation system 1 is shown in FIG. A waveform recognition circuit 46B is provided.

  As shown in FIG. 16, the waveform recognition circuit 46B includes a bandpass filter 46a, an A / D converter 61, a waveform memory 62, a discrete Fourier transform circuit (hereinafter referred to as DFFT) 71, And a registered waveform memory 63A.

  The DFFT 71 provided in the second embodiment performs a discrete Fourier transform process on the output sound waveform data from the waveform memory 62 to acquire a frequency coefficient corresponding to the frequency of the output sound waveform data, and supplies it to the CPU 45.

The registered waveform memory 63A stores frequency coefficients 64a to 64c in the output sound waveform data for each model 8A to 8C of the electric knife 8.
For example, the registered waveform memory 63A includes a frequency coefficient 64a of output sound waveform data based on the model name 8A (UES-20), a frequency coefficient 64b of output sound waveform data based on the model name 8B (UES-30), and a model The frequency coefficient 64c of the output sound waveform data based on the name 8C (PSD-30) is stored. However, the present invention is not limited to this, and the frequency coefficient of the output sound waveform data of other different models may be registered.

  Each registered frequency coefficient for each model stored in the registered waveform memory 63A is read out by reading control by the CPU 45.

  Note that the endoscope system of the present embodiment can register output sound waveform data of any model in the registered waveform memory 63A.

  FIG. 18 shows a comparison frequency count registration screen 14B when a comparison frequency coefficient input operation is performed in the predetermined electric knife 8 in this case.

As shown in FIG. 18, when the comparison frequency coefficient registration mode execution is operated by the centralized operation panel 14 or the like, the CPU 45 displays a comparative frequency coefficient registration screen 14B on the centralized operation panel 14.
The comparison frequency coefficient registration screen 14B is obtained by performing output Fourier waveform data (A / D converter output waveform data) 61a from the waveform memory 62 and discrete Fourier transform processing on the output waveform data 61a. A frequency coefficient 65 corresponding to the frequency of the output sound waveform data 61a and a registration button 50B for registering the frequency coefficient 65 are provided.

  With this configuration, it is possible to register the frequency coefficient 65 of the output sound waveform data in the electric knife 8 of any model by appropriately operating using the comparison frequency coefficient registration screen 14B provided on the centralized operation panel 14. it can.

In this case, as shown in FIG. 20, even if the output 71a of the DFFT 71 is the phase period L1 of the output waveform data 61a of the A / D converter output 61, the phase period L2 is different from the phase period L2. However, since the frequency coefficient 64a is the same, it is not necessary to consider the phase shift as in the second embodiment.
Other configurations are substantially the same as those of the second embodiment.

  Next, the control operation by the CPU 45 in the endoscope system of the present embodiment will be described with reference to FIGS.

  In the endoscope system of this example, when the power is turned on, the CPU 45 of the system controller 15 reads and starts the program shown in FIG. 21 stored in an internal memory (not shown).

  As shown in FIG. 21, the program started by the CPU 45 is provided with a process of step S20 between steps S13 and S14 of the program (see FIG. 15) in the second embodiment, and the program in the second embodiment. Steps S15 and S16 of the program are deleted. The processing from step S1 to step S13 is the same as that in the second embodiment.

  In the process of step S20, the CPU 45 performs a discrete Fourier transform process on the output sound waveform data from the waveform memory 62 by the DFFT 71, obtains a frequency coefficient corresponding to the frequency of the output sound wave data, and proceeds to step S21.

  In the determination process of step S21, the CPU 45 compares the frequency coefficient corresponding to the frequency of the output sound waveform data, which is the output of the DFFT 71, with the registered frequency coefficient read from the registered waveform memory 63A. The process proceeds to S5, and if they do not match, the process proceeds to step S6.

  Then, as in the second embodiment, the CPU 45 determines that the electric knife 8 is in the output state when they coincide with each other, and drives the smoke exhausting operation by the insufflation apparatus 9 by the process of step S5. To control. Then, the process returns to step S1.

  On the other hand, if they do not match, it is determined that the electric knife 8 is not in the intended output state, and the CPU 45 controls so as not to drive the smoke exhausting operation by the insufflation apparatus 9 by the process of step S6. Then, the process returns to step S1.

That is, in the present embodiment, as described with reference to FIG. 20, the output 71a of the DFFT 71 is different from the phase period L2 even in the phase period L1 of the output waveform data 61a of the A / D converter 61. Since the frequency coefficient 64a is the same even in the phase period L2, it is not necessary to consider the mismatch due to the phase shift as in the second embodiment. As a result, the processes in steps S15 and S16 in the second embodiment can be deleted.
Other operations are the same as those in the second embodiment.

  Therefore, according to the present embodiment, in addition to the effects of the second embodiment, the comparison process can be performed even if the period (phase) of the output sound waveform data to be compared is accurately detected. This can contribute to simplification of the control procedure and cost reduction.

  That is, as shown in FIG. 23, the CPU 45 performs steps S10 to S10 only when it is determined by the determination processing in step S4 that the output signal as a comparison result by the comparator is a “High” signal. The routine of S16 is executed to compare the output sound waveform data with the registered waveform data, and the smoke exhausting operation of the pneumoperitoneum 9 is controlled by the process of step S5 or step S6 based on the comparison result.

  Other operations are the same as those in the first and second embodiments.

  Therefore, according to the present embodiment, in addition to the effects of the second embodiment, the comparison calculation process is performed only when the output sound data of the electric knife 8 is detected. Therefore, the load on the CPU 45 can be reduced as compared with the second embodiment. it can.

  That is, as shown in FIG. 25, the CPU 45 performs steps S10 to S10 only when it is determined by the determination processing in step S4 that the output signal as a comparison result by the comparator is a “High” signal. The routine up to S13, Step S20 and Step S21 is executed to compare the frequency count of the output sound waveform data with the frequency coefficient of the registered waveform data. Based on the comparison result, the pneumothorax apparatus 9 controls the smoke emission operation.

  Other operations are the same as those in the first and third embodiments.

  Therefore, according to the present embodiment, in addition to the effects of the third embodiment, the comparison calculation process is performed only when the output sound data of the electric knife 8 is detected, so that the load on the CPU 45 can be reduced as compared with the third embodiment. it can.

  In addition, you may apply the technique mentioned later to the endoscope system which concerns on the said 1st-5th Example of this invention. Such a technique will be disclosed with reference to FIGS.

  26 is a diagram showing a defect input screen displayed on the centralized operation panel, FIG. 27 is a display screen of the monitor screen after the endoscope system is turned on, and FIG. 28 is a display of the centralized operation panel after the endoscope system is turned on. It is a screen.

  In the conventional example, if a device with a malfunction or other problem found during surgery is used the next day without a noticed by a different operator on the next day, the device is connected when the device is used during surgery. The same inconvenience may occur only when the device is turned on.

  However, the endoscope system according to the present invention is configured to avoid the same problem due to forgotten transmission in view of the above problems.

  That is, the CPU 45 displays the trouble input screen 14A1 shown in FIG. 26 on the centralized operation panel 14 when the endoscope system power is turned on. As shown in FIG. 26, the defect input screen 14A1 can be operated to input items such as “defective device”, “phenomenon”, “input person”, and “date”.

  Therefore, the surgeon inputs the defective device, the content of the defect, and other contents using the defect input screen 14A1 shown in FIG. Then, the CPU 45 stores the input information input by performing the input operation on the defect input screen 14A1 in the memory 49 or a memory (not shown) in the CPU 45.

  Next, when the endoscope system is turned on next time, the CPU 45 reads the input information when the input information is stored in the memory 49 or a memory (not shown) in the CPU 45, and reads out the input information. The input information is displayed on at least one of the screen 12A on the monitor 12 (or 27) in FIG. 27 and the panel screen 14B1 on the centralized operation panel 14 in FIG.

  Further, the CPU 45 stores a self-diagnosis program for automatically detecting a failure part or a failure of a connected device (not shown) in an internal memory, and executing the self-diagnosis program solves the problem. When a connected device is detected, the failure information of the connected device is stored in the memory 49 or a memory (not shown) in the CPU 45.

  When the power of the endoscope system is turned on next time, if the trouble information is stored in the memory 49 or a memory (not shown) in the CPU 45, the power of the trouble connecting device is turned off. However, the defect information is read, and the read defect information is displayed on at least one of the screen 12A on the monitor 12 (or 27) in FIG. 27 and the panel screen 14B1 on the centralized operation panel 14 in FIG. Let

  As a result, the endoscope system itself stores the trouble that must be transmitted to the operator who uses the endoscope system, and the stored contents are automatically displayed at the next start-up, so that the transmission items are reliably transmitted. Therefore, it is possible to avoid problems due to forgetting to transmit.

  The trouble input screen 14A1 displayed on the centralized operation panel shown in FIG. 26 is not limited to this. For example, the transmission item input screen 14C1 as shown in FIG. 29 or the automatic input as shown in FIG. The notification information may be input and stored using the notification item input screen 14E1 having a notification date input item in which a notification date or a notification period to be notified can be input.

  A display example at this time when the endoscope system is turned on next time is shown in FIG. 30 and FIG. That is, when the power of the endoscope system is turned on next time, the CPU 45 reads the transmission information when the transmission information is stored in the memory 49 or a memory (not shown) in the CPU 45, and reads the read information. The transmission information is displayed on at least one of the screen 12B on the monitor 12 (or 27) in FIG. 30 and the panel screen 14D1 on the centralized operation panel 14 in FIG.

  Further, when the notification date information is stored together with the transmission information in the memory 49 or a memory (not shown) in the CPU 45, the CPU 45 reads the transmission information and the notification date information, and reads the notification date information according to the notification date of the notification date information. The read transmission information is displayed on at least one of the screen 12B on the monitor 12 (or 27) in FIG. 30 and the panel screen 14D1 on the centralized operation panel 14 in FIG. As a result, the same effect as described above can be obtained.

  The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.
