0001The present invention relates to a medical system.
0002Endoscopic surgical methods for the heart include inserting an endoscope into the sac from the vicinity of the xiphoid process for observation and various treatments. The merit of this method is that it enables minimally invasive surgery with a small surgical wound, as opposed to the treatment of heart disease that was conventionally performed surgically under thoracotomy, and the burden on the patient is extremely small. Can be mentioned.
0003In endoscopic surgery using an intracardiac approach, it is desirable to make the incision area in which the device is inserted very small in order to aim for minimal invasiveness. Specifically, a sheath is inserted into a small incision, and an endoscope or a treatment device is inserted into the cardiac sac through the sheath for observation and various treatments. In such a surgical method, there are various endoscopes and treatment devices to be inserted into the cardiac sac. For example, endoscopes include side-view endoscopes and direct-view endoscopes with different optical systems, flexible endoscopes and rigid endoscopes with different hardness and shape of insertion part, and ultra-ultrascopic endoscopes that have not only optical observation but also ultrasonic diagnostic functions. There are sonic endoscopes and the like. These are used properly according to the situation in one operation, and in some cases, they are frequently replaced.
0004On the other hand, the processor that drives the endoscope is often not designed to drive different types of endoscopes. The reason is the bloated processor. In that case, since a dedicated processor corresponding to each endoscope is required, it has been necessary to prepare a dedicated image display device corresponding to each processor. Even if an image display device capable of supporting different types of video formats is used, it takes time and effort to reconnect the connection between the processor and the image display device every time the endoscope is replaced.
0005Therefore, when using a plurality of endoscopes, the video signal switching device of the endoscope system that aggregates the video signals output from each processor once and selects and switches the video signals to be input to the image display device. Has been proposed (see, for example, Patent Document 1).

However, there is still the trouble of manually switching the image to be displayed on the image display device. It suffices if the image display device is always within the reach of the operator, but this is not always the case, and therefore it is difficult to instantly switch the video signal each time the endoscope is replaced. As the surgery becomes more sophisticated and complex, and the system becomes bloated, the distance between the surgeon and the image display device may still increase. Therefore, conventionally, there is a disadvantage that it is difficult and troublesome to instantly switch the image information to be displayed on the display unit in association with each time the endoscope or treatment tool to be used is switched.</p><p num="0008"> The present invention provides a medical system that can easily switch by associating the information of the insertion part to be displayed on the display part each time the insertion part of the imaging device or the treatment device to be inserted into the body cavity of the living body is switched.

0029[First Embodiment] The medical system according to the first embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the medical system 100 according to the present embodiment includes an endoscope device (medical device) 1 having a plurality of insertion portions 10A and 10B that can be inserted into the body cavity of the living body, and the living body. A sheath unit (mantle tube) 3 that is attached and guides the insertion portions 10A and 10B of the endoscope device 1 into the body cavity of the living body, and a monitor (display unit) 5 that displays images and the like acquired by the endoscope device 1. And have.
0030The endoscope device 1 includes two insertion portions 10A and 10B such as an endoscope, and a main body portion 20 that supports these insertion portions 10A and 10B. The insertion portions 10A and 10B each have an elongated substantially cylindrical shape, and the base end portion is fixed to the main body portion 20 or is detachably attached. Further, the insertion portions 10A and 10B each include a CCD (imaging element) 11 for acquiring an image. Each CCD 11 is arranged at the tip of the insertion portions 10A and 10B so that the image pickup signal of the acquired image can be sent to the main body portion 20.
0031In addition, barcodes (identification information generators) 13A and 13B that display unique identification information (insertion part identification information) for each insertion part 10A and 10B are marked on the outer cylindrical surface near the tips of the insertion parts 10A and 10B. Has been done. The barcodes 13A and 13B have a plurality of high-reflectance parts having a high reflectance and a plurality of low-reflectance parts having a low reflectance, which are composed of different combinations for each of the insertion portions 10A and 10B. The high-reflectance portion and the low-reflectance portion are arranged along the longitudinal direction of the insertion portions 10A and 10B, respectively.
0032When these insertion portions 10A and 10B are inserted into the body cavity of the living body, the sheath unit 3 attached to the living body can be selectively passed through. When the insertion portions 10A and 10B pass through the sheath unit 3, the identification information of the barcodes 13A and 13B is sent to the main body portion 20 via the sheath unit 3.
0033As shown in FIG. 2, the sheath unit 3 includes a hollow tube-shaped sheath 40 having a through hole 40a through which the insertion portions 10A and 10B of the endoscope device 1 can pass, and an insertion portion 10A through which the sheath 40 passes. It is equipped with an identification signal generation unit (identification information output unit) 50 that acquires the identification information of 10B and outputs it to the main unit 20. The sheath unit 3 can be attached to the living body by inserting one end of the sheath 40 into the opening of the living body.
0034The identification signal generation unit 50 is built in the base end portion of the sheath 40. The identification signal generation unit 50 includes an LED light source (light source unit) 51 that emits infrared light toward the through hole 40a of the sheath 40, an LED driver 53 that drives the LED light source 51, and infrared rays emitted from the LED light source 51. A photodiode (detection unit) 55 that detects reflected light and converts it into an electric signal, a signal amplification unit 57 that amplifies the electric signal obtained by the photodiode 55, and a signal amplification unit 57 that converts the amplified electric signal into electromagnetic waves. It is equipped with a transmission antenna 59 that transmits light to the main body 20.
0035In the photodiode 55, when the insertion portion 10A or the insertion portion 10B of the endoscope device 1 passes through the through hole 40a of the sheath 40, the infrared light emitted from the LED light source 51 emits the barcode 13A (insertion) of the insertion portion 10A. By irradiating the barcode 13B) in the case of the portion 10B, it is possible to detect the reflected light reflected by the barcodes 13A and 13B and acquire an electric signal indicating the identification information of the insertion portions 10A and 10B. It has become like. As a result, the identification information of the insertion portions 10A and 10B is sent to the main body portion 20 via the signal amplification portion 57 and the transmission antenna 59.
0036As shown in FIG. 1, the main body 20 has a receiving antenna 21 that receives electromagnetic waves indicating identification information of the insertion portions 10A and 10B sent from the transmitting antenna 59 of the sheath unit 3 and converts them into electric signals. , The power ON / OFF of the monitor 5 is switched based on the signal conversion unit 23 that performs level conversion and data string conversion of the electric signal obtained by the receiving antenna 21 and the electric signal sent from the signal conversion unit 23. It is equipped with a power switching unit 25.
0037Further, the main body 20 is sent from the image processing units 27A and 27B that convert the imaging signals sent from the CCD11s of the insertion units 10A and 10B into video signals (individual information of the insertion unit) and the signal conversion units 23. An image selector (control unit) 29 that selects one of the video signals obtained by the image processing units 27A and 27B based on the identification information of the incoming electrical signal and displays the selected video signal on the monitor 5 and inserts the image selector (control unit) 29. It is provided with a memory 31 that stores the identification information of parts 10A and 10B as a data array in advance.
0038The operation of the medical system 100 configured in this way will be described. In order to observe the inside of the body cavity of the living body by the medical system 100 according to the present embodiment, first, as shown in FIG. 3, the incised portion of the living body S (in FIG. 3, a puncture point formed in the epicardium). ), Insert the tip of the sheath 40 of the sheath unit 3, and attach the sheath unit 3 to the living body S.
0039In the sheath unit 3, infrared light is generated from the LED light source 51 of the identification signal generation unit 50. In this state, an image is acquired by CCD11 of each insertion unit 10A, 10B, and each video signal is sent to the image selector 29 via the image processing unit 27A, 27B, but the image is displayed on the monitor 5. Not done.
0040Next, one of the insertion portions 10A and 10B of the endoscope device 1 is inserted into the body cavity of the living body S through the sheath 40 of the sheath unit 3. For example, as shown in FIG. 4A, when the insertion portion 10A is inserted into the sheath unit 3, the bar code 13A of the insertion portion 10A passes under the optical path of the infrared light emitted from the LED light source 51, whereby the bar is barred. The code 13A is irradiated with infrared light, and the reflected light is detected by the photodiode 55.
0041The reflected light detected by the photodiode 55 is converted into an electric signal indicating the identification information of the barcode 13A. This electric signal becomes a serial coded signal by bar code scanning with infrared light. For example, as shown in FIG. 4 (b), the coded signal when the insertion portion 10A is inserted into the sheath 40 is set to "101000110". After being amplified by the signal amplification unit 57, the coded signal is converted into electromagnetic waves by the transmission antenna 59 and transmitted to the main unit 20.
0042The electromagnetic wave propagating in the air is received by the receiving antenna 21 of the main body 20 and converted into an electric signal, and after level conversion and data string conversion by the signal conversion unit 23, it is input to the image selector 29 and the power supply switching unit 25. Will be done. The image selector 29 collates the data array of the electric signal indicating the identification information of the insertion unit 10A input from the signal conversion unit 23 with the data array of the identification information of the insertion units 10A and 10B stored in the memory 31. To.
0043In this case, since the data sequences related to the identification information of the insertion portion 10A match, the image selector 29 recognizes that the insertion portion 10A is currently used (inserted into the body cavity), and the insertion portion 10A is recognized. 10A is identified. Then, the image selector 29 selects the video signal sent from the image processing unit 27A, and as shown in FIG. 5, the image in the body cavity of the living body S captured by the insertion unit 10A is displayed on the monitor 5. .. As a result, the operator can observe the inside of the body cavity of the living body S while looking at the image on the monitor 5 captured by the insertion portion 10A.
0044Subsequently, when the observation by the insertion portion 10A is completed and the insertion portion 10A is pulled out from the sheath unit 3, the barcode 13A passes under the optical path of the infrared light by the LED light source 51 at that time. In this case, since the scanning direction of the barcode 13A by infrared light is opposite to that at the time of insertion, the coded signal obtained by converting the reflected light detected by the photodiode 55 is also opposite to that at the time of insertion. For example, as shown in FIG. 4 (b), the coded signal at the time of removing the insertion portion 10A from the sheath 40 is set to "011000101".
0045The coded signal obtained by the photodiode 55 is received by the receiving antenna 21 of the main body 20 via the signal amplification unit 57 and the transmitting antenna 59 and converted into an electric signal, and is converted into a signal, as in the case of insertion. It is input to the image selector 29 and the power switching unit 25 via the unit 23. This electric signal indicates that the insertion portion 10A has been removed.
0046As shown in FIG. 6, the image selector 29 stops the output of the video signal to the monitor 5 with this electric signal as a trigger, and the power switching unit 25 sets the power supply of the monitor 5 to the energy saving mode.
0047Next, a case where the insertion portion 10B is inserted into the sheath unit 3 will be described. When inserting the insertion portion 10B into the sheath unit 3, the basic operation is the same as when inserting the insertion portion 10A. As shown in FIG. 7, when the insertion portion 10B passes through the sheath 40 of the sheath unit 3, the image selector 29 recognizes that the insertion portion 10B is currently used (inserted into the body cavity). , The insertion unit 10B is identified and the video signal sent from the image processing unit 27B is selected. As a result, as shown in FIG. 8, the image in the body cavity of the living body S captured by the insertion portion 10B is displayed on the monitor 5.
0048Similarly, when the insertion unit 10B is removed from the sheath unit 3, the image selector 29 sends the image selector 29 to the monitor 5 using an electric signal indicating that the insertion unit 10B acquired by the identification signal generation unit 50 has been removed as a trigger. The output of the video signal is stopped, and the power supply of the monitor 5 is set to the energy saving mode by the power supply switching unit 25.
0049As described above, according to the medical system 100 according to the present embodiment, each insertion portion 10A, 10B has each time the plurality of insertion portions 10A, 10B of the endoscope device 1 are inserted and replaced with the sheath unit 3. By acquiring unique identification information and identifying the currently used insertion portions 10A and 10B, the insertion portion 10A to be displayed on the monitor 5 in association with the switching of the insertion portions 10A and 10B to be inserted into the living body S. , 10B images can be easily switched.
0050As a result, it is possible to save the operator the trouble of switching the image to be displayed on the monitor 5 in accordance with the switching of the insertion portions 10A and 10B. In addition, power saving can be achieved by automatically setting the monitor 5 to the energy saving mode except when the insertion portions 10A and 10B are used.
0051The barcodes 13A and 13B are difficult to read if there are deposits such as blood. Therefore, in the present embodiment, for example, the insertion portions 10A and 10B may be provided with a water-repellent coating to prevent the deposits from adhering to the barcodes 13A and 13B. Further, for example, when a sponge is attached near the entrance of the through hole 40a of the sheath 40 and the insertion portions 10A and 10B are inserted into the sheath 40, the sponge removes dirt on the surface of the insertion portions 10A and 10B to facilitate scanning reading. You may try to do it.
0052This embodiment can be modified as follows. In the present embodiment, one identification signal generation unit 50 is arranged on the proximal end side of the sheath 40, but instead, for example, the sheath unit 3 identifies as shown in FIG. The same identification signal generation unit as the signal generation unit 50 may be further provided. For example, the identification signal generation unit 50 and the identification signal generation unit 52 may be arranged at intervals along the longitudinal direction of the sheath 40. The identification signal generation unit 50 and the identification signal generation unit 52 are used in this order from the inlet side of the sheath unit 3.
0053In this case, as shown in FIG. 10, when the insertion portion 10A is inserted into the sheath 40 of the sheath unit 3, the barcode 13A passes through the identification signal generation unit 50 and the identification signal generation unit 52 in this order. Then, the electric signal as the identification information of the bar code 13A obtained by irradiating the infrared light with the LED light source 51 and detecting the reflected light with the photodiode 55 is also in the order of the identification signal generation unit 50 and the identification signal generation unit 52. It is generated and sent to the signal amplification unit 57, the transmission antenna 59, the reception antenna 21, the signal conversion unit 23, the image selector 29, and the power supply switching unit 25 in that order.
0054In this case, as shown in FIG. 11, the electric signal as the identification information transmitted from the identification signal generation unit 50 and the electric signal as the identification information transmitted from the identification signal generation unit 52 can be identified. It is desirable that the upper 1 bit of the coded signal indicating the identification information of the insertion unit 10A acquired for each of the identification signal generation units 50 and 52 is used as the source identification signal. By doing so, it can be determined whether the insertion operation is performed or the extraction operation is performed in the order of the upper 1 bits (for example, 1 0 or 0 1) input to the image selector 29 in chronological order. It can be easily judged.
0055According to this modification, the two identification signal generation units 50 and 52 read the barcodes 13A and 13B in order, respectively, so that the insertion units 10A and 10B can be inserted regardless of the shape of the barcodes 13A and 13B. The insertion operation and the removal operation of the can be easily discriminated. For example, in the above embodiment, in order to distinguish between the operation at the time of insertion and the operation at the time of removal, it is necessary to read the barcodes 13A and 13B serially, so that the bars are along the longitudinal direction of the insertion portions 10A and 10B. There is a restriction that the codes 13A and 13B must be arranged (they must be arranged in consideration of the scanning direction and made into a one-dimensional symbol), but according to this modification, the symbol shape and the insertion and removal are performed. Since the operation discrimination is not related, various shapes such as free-form two-dimensional symbols and matrix symbols can be freely selected as the barcodes 13A and 13B.
0056[Second Embodiment] Next, the medical system according to the second embodiment of the present invention will be described. In the medical system 200 according to the present embodiment, as shown in FIG. 12, the insertion portions 10A and 10B can output unique identification information (insertion portion identification information) instead of the barcodes 13A and 13B RFID (Radio).

It is equipped with 155 and a receiving antenna 157 that receives a carrier wave from RFID tags 113A and 113B and converts it into an electric signal. The identification signal generation unit 50 amplifies the electric signal obtained by the receiving antenna 157 by the signal amplification unit 57, converts the electric signal amplified by the signal amplification unit 57 into an electromagnetic wave by the transmission antenna 59, and converts it into an electromagnetic wave. It is supposed to send to 20.
0059The main body 20 includes a memory (storage unit) 121 that temporarily stores a data array of identification information input from the signal conversion unit 23 by the image selector 29. When the electrical signal of the identification information is input from the signal conversion unit 23, the image selector 29 determines whether or not the data array of the electrical signal and the data array of the identification information stored in the memory 121 match. It has become like.
0060The operation of the medical system 200 configured in this way will be described. In order to observe the inside of the body cavity of a living body by the medical system 200 according to the present embodiment, the sheath unit 3 is attached to the living body, and an electromagnetic wave including a control signal is transmitted from the transmitting / transmitting antenna 155 of the identification signal generation unit 50.
0061When the insertion portion 10A is inserted into the sheath 40 of the sheath unit 3, as shown in FIG. 15, the RFID tag 113A passes under the electromagnetic wave emitted by the transmission / transmission antenna 155, so that the RFID tag 113A antenna 167 allows the insertion portion 10A to pass through. Electromagnetic waves are received. In the antenna 167, an electromotive force is generated by a resonance action (electromagnetic induction) when an electromagnetic wave is received. The generated electromotive force is sent to the power supply unit 165, and the power supply unit 165 generates a power source for driving the control unit 163. A part of the electromotive force includes a control signal. The control signal is input to the A / D conversion unit 162B of the control unit 163.
0062The A / D converter 162B decodes the control signal sent from the antenna 167 and sends it to the memory 161. In the memory 161, an electric signal of the stored identification information is transmitted to the control unit 163 based on the input control signal. In the control unit 163, the electric signal is encoded by the D / A conversion unit 162A, modulated into a carrier wave, and sent to the antenna 167.
0063The carrier wave is transmitted inside the sheath 40 by the antenna 167, received by the receiving antenna 157 of the identification signal generator 50, and converted into an electric signal. The electric signal is amplified by the signal amplification unit 57, input to the transmission antenna 59, converted into electromagnetic waves, and transmitted to the main body unit 20.
0064The electromagnetic wave propagating in the air is received by the receiving antenna 21 of the main body 20, converted into an electric signal, and input to the signal conversion unit 23.

To.
0066Subsequently, when the insertion unit 10A is pulled out from the sheath unit 3, an electric signal having the same identification information as at the time of insertion is input to the image selector 29 and the power supply switching unit 25. In this case, the image selector 29 and the power switching unit 25 determine that the same electric signal data array has been input twice in succession, so that the image selector 29 stops sending the video signal to the monitor 5. At the same time, the power supply switching unit 25 sets the power supply of the monitor 5 to the energy saving mode.
0067A method for determining that the same data array has been input twice in succession will be described with reference to the flowchart of FIG. In FIG. 16, the preceding data array of the identification information stored in the memory 121 is X0, and the following data array is X1. When an electric signal (data array X1) indicating the identification information of the insertion portions 10A and 10B is input to the image selector 29 (step SA1), the data array X1 of the electric signal is temporarily stored in the memory 121 (step). SA2).
0068First, the image selector 29 collates the data array X1 of the new electric signal with the data array of the identification information of the insertion portions 10A and 10B stored in the memory 31 (step SA3). When the data arrays match as a result of collation, the image selector 29 then collates the trailing data array X1 of the electrical signal with the preceding data array X0 stored in the memory 121 (step SA4).
0069If the collation results match in step SA4, the image selector 29 stops the transmission of the video signal of the insertion unit 10A using the subsequent row data array X1 as identification information (step SA5). Also, by the power switching unit 25. The power of monitor 5 is set to energy saving mode (step SA6). Further, the image selector 29 erases all the data in the memory 121 and resets it (step SA7).
0070On the other hand, in step SA4, if the collation results do not match, the video signal of the insertion unit 10A using the data array X1 as the identification information is displayed on the monitor 5 (step SA8), and the identification information newly stored in the memory 121 is displayed. The trailing data array X1 is overwritten by the leading data array X0 and retained as the leading data array X0 (step SA9). FIG. 17 shows the relationship between the data array of the electrical signal of the identification information input to the image selector 29, the leading data array X0 and the trailing data array X1 of the identification information stored in the memory 121, and the display state of the monitor 5.

0078The image processing unit 235 transmits the identification information of the insertion unit 10A and the sheath unit 3A to the OSD generation unit 223. The OSD generation unit 223 reads the character information (insertion unit 10A and sheath unit 3A) of the insertion unit 10A and the sheath unit 3A corresponding to the identification information of the insertion unit 10A and the sheath unit 3A from the memory 221. Each is converted into a video signal. The image processing unit 235 superimposes the video signals obtained by the OSD generation unit 223, that is, the characters "insertion unit 10A" and "sheath unit 3A" on the image captured by the insertion unit 10A, and displays them on the monitor 5.

It is different from the first to third embodiments. Hereinafter, the parts having the same configuration as the medical systems 100, 200, 300 according to the first to third embodiments are designated by the same reference numerals and the description thereof will be omitted.

0096The electric signal acquired by the identification signal generation unit 50 is transmitted from the transmission antenna 59 to the main body 20, received by the reception antenna 21, and passes through the signal conversion unit 23 to the image selector 29 and the power supply switching unit 25. And is input to the LED control unit 323 (step SB1).
0097The LED control unit 323 inputs the electric signal sent from the signal conversion unit 23 to the memory 327 and temporarily stores it (step SB2), and at the same time, the data array of the electric signal and the identification information stored in the memory 325. Is collated with the data sequence of (step SB3), and it is recognized that the insertion portion 10A is currently inserted in the sheath unit 3.
0098Next, the electric signal temporarily stored in the memory 327 is sent to the LED control unit 323. The array data of this electric signal is the data transmitted by the signal conversion unit 23 when the insertion unit 10A is inserted into the sheath unit 3.
0099The LED control unit 323 compares the array data X1 of the electric signal transmitted from the signal conversion unit 23 with the array data X0 of the electric signal temporarily stored in the memory 327 (step SB4). When the LED control unit 323 determines that these data arrays X1 and X0 match, it is recognized that the extraction operation has been performed, and an instruction to reduce the amount of emitted light of the lighting LED 315 or an instruction to turn off the lighting LED 315. Is input to the LED drive unit 321A.
0100The LED drive unit 321A reduces the amount of emitted light of the illumination LED 315 or turns off the illumination LED 315 according to the instruction of the LED control unit 323 (step SB7). In this case, the LED control unit 323 erases all the identification signal data stored in the memory 325 (step SB8). FIG. 29 shows the data array of the electrical signal of the identification information input to the LED control unit 323, the leading data array X0 and the trailing data array X1 of the identification information stored in the memory 327, and the lighting state of the lighting LED 315. Shows the relationship. The case of inserting the insertion portion 10B into the living body S and the case of removing the insertion portion 10B from the living body S are the same as those of the insertion portion 10A, and thus the description thereof will be omitted.
0101As described above, according to the medical system 400 according to the present embodiment, the inside of the body cavity of the living body is illuminated by the lighting LED 315 in conjunction with the insertion operation and the removal operation of the insertion portions 10A and 10B into the body cavity of the living body. The illumination light can be changed automatically. As a result, the operator's operational burden can be reduced and visibility can be prevented from being obstructed.
0102For example, if the inserts 10A and 10B are outside the body but the lights are on, the light may enter the operator's field of view and interfere with the surgery. It is conceivable to turn off the lights manually when not in use, but in the surgical scene where the insertion is frequently replaced, switching between turning on and off is often performed, which complicates the operation. In the present embodiment, when the insertion portions 10A and 10B are outside the body, the lighting LED 315 is turned on or off, and when the insertion portions 10A and 10B are inserted inside the body, the lighting LED 315 is turned on or off. Therefore, observation can be performed efficiently.
0103In the present embodiment, the LED 315 for lighting is arranged at the tips of the insertion portions 10A and 10B, but instead of this, for example, fibers are arranged in the insertion portions 10A and 10B along the longitudinal direction thereof. At the same time, the illumination LED may be arranged at the base end portion of the fiber, and the light from the illumination LED may be guided to the tips of the insertion portions 10A and 10B via the fiber.
0104Further, in the present embodiment, the insertion portions 10A and 10B are identified by the RFID tags 113A and 113B, but as in the first embodiment, the insertion portions 10A and 10B are identified by the barcodes 13A and 13B. The lighting LED 315 may be turned on / off or the illumination light amount may be increased / decreased in conjunction with the insertion / removal operations of the insertion portions 10A and 10B determined by reading the barcodes 13A and 13B.
0105[Fifth Embodiment] Next, the medical system according to the fifth embodiment of the present invention will be described. As shown in FIG. 30, the medical system 500 according to the present embodiment is a moving image recording unit in which the main body 20 of the endoscope device 1 records a moving image sent from the image processing units 27A and 27B to the image processing unit 225. (Image recording unit) It differs from the first to fourth embodiments in that it includes a 421. Hereinafter, the parts having the same configuration as the medical systems 100, 200, 300, 400 according to the first to fourth embodiments are designated by the same reference numerals and the description thereof will be omitted.
0106The image selector 29 compares the data array of the identification information of the newly identified insertion unit 10A or the insertion unit 10B with the data array of the identification information immediately stored in the memory (storage unit) 121, and these data sequences are obtained. When they are different from each other, the image captured by the newly identified insertion unit 10A or insertion unit 10B is recorded by the moving image recording unit 421, and when these data sequences match each other, the recording by the moving image recording unit 421 is stopped. It has become like.
0107The operation of the medical system 500 configured in this way will be described with reference to the flowchart of FIG. In FIG. 31, similarly to FIG. 16, the preceding data array of the identification information stored in the memory 121 is X0, and the following data array is X1. In the medical system 500 according to the present embodiment, as shown in FIG. 32, the insertion unit 10A is inserted into the sheath unit 3, and an electric signal indicating the identification information of the insertion unit 10A acquired by the identification signal generation unit 50 is an image. When input to the selector 29 (step SC1), the electric signal transmitted from the signal conversion unit 23 is temporarily stored in the memory 121 (step SC2), and the latest electric signal data array and memory are stored by the image selector 29. The data sequence of the identification information stored in 31 is collated (step SC3).
0108The image selector 29 recognizes that the insertion portion 10A is currently inserted into the sheath unit 3. Next, the memory 121 temporarily stores an electric signal indicating the identification information sent at the time of the previous insertion / removal operation, which is sent to the image selector 29. The electric signal of the identification information stored in the memory 121 is overwritten each time the electric signal is input.
0109The image selector 29 compares the latest electrical signal data array X1 transmitted from the signal converter 23 with the electrical signal data array X0 temporarily stored in the memory 121 (step SC4). In the insertion operation of the insertion unit 10A, the electric signals of these two have different data arrangements.
0110When the image selector 29 determines that these data arrays X0 and X1 are different, the video recording unit 421 is instructed to start video recording. The video recording unit 421 records the video signal transmitted from the image processing unit A in response to the instruction of the image selector 29 (step SC5). In this case, the data array of the identification information stored in the memory 121 is held (step SC6).
0111Subsequently, as shown in FIG. 33, when the insertion unit 10A is removed from the sheath unit 3, the electric signal acquired by the identification signal generation unit 50 is input to the image selector 29 and the power supply switching unit 25 as in the case of insertion. Is done (step SC1). Then, the electric signal transmitted from the signal conversion unit 23 is temporarily stored in the memory 121 (step SC2), and the latest electric signal data array and the identification information data stored in the memory 31 are stored by the image selector 29. The sequence is matched (step SC3) and it is recognized that the insertion part 10A is currently inserted into the sheath unit 3.
0112Next, the electric signal temporarily stored in the memory 121 is sent to the image selector 29. The data arrangement of this electric signal is the data transmitted by the signal conversion unit 23 when the insertion unit A is inserted into the sheath unit 3.
0113The image selector 29 compares the data array X1 of the electric signal transmitted from the signal conversion unit 23 with the data array X0 of the electric signal temporarily stored in the memory 121 (step SC4). In the insertion / removal operation of the insertion unit 10A, the signals of these two are the same data array. When the image selector 29 determines that these data arrays X0 and X1 match, it recognizes that the extraction operation has been performed, and instructs the moving image recording unit 421 to stop the moving image recording.
0114The moving image recording unit 421 stops the moving image recording in response to the instruction of the image selector 29 (step SC7). In this case, the image selector 29 erases the data array of the identification information stored in the memory 121 (step SC8) and resets it. FIG. 34 shows the data array of the electrical signal of the identification information input to the image selector 29, the preceding data array X0 and the following data array X1 of the identification information stored in the memory 121, and the recording state of the moving image recording unit 421. Shows the relationship. Since the case of the insertion portion 10B is the same as that of the insertion portion 10A, the description thereof will be omitted.
0115According to the medical system 500 according to the present embodiment, the image acquired by the insertion unit 10A is the image recording unit 421 only while the same insertion portion 10A of the endoscopic device 1 is inserted into the body cavity of the living body. When the insertion part 10A is taken out from the body cavity of the living body, the image recording by the image recording part 421 is stopped, so that every time the insertion part 10A or 10B to be used is switched, the necessary body cavity of the living body is used. Only the images inside can be recorded efficiently.
0116Further, in the present embodiment, the insertion portions 10A and 10B are identified by the RFID tags 113A and 113B, but as in the first embodiment, the insertion portions 10A and 10B are identified by the barcodes 13A and 13B. The moving image recording may be started and stopped in conjunction with the insertion and removal operations of the insertion portions 10A and 10B determined by reading the barcodes 13A and 13B. The same applies to the action of increasing or decreasing the amount of backlight light of the monitor 5.
