The present invention relates to a body cavity introduction device introduced into a body cavity, for example, an indwelling device for body cavity introduction device that places a swallowable capsule endoscope in the body cavity, and a body cavity introduction device placement system.
In recent years, in the field of endoscopes, capsule endoscopes equipped with an imaging function and a wireless function have appeared. This capsule endoscope is used for observation (examination) after being swallowed by the subject, the observation period until it is naturally discharged from the subject's living body (human body), stomach, small intestine, etc. The inside of the organ (inside the body cavity) is moved in accordance with the peristaltic motion, and is sequentially imaged using the imaging function.
In this type of capsule endoscope, for example, there is a swallow type as shown in Patent Document 1, and the driving of an electric load for performing an imaging function, a wireless function, or the like in the capsule endoscope is controlled. Therefore, a configuration has been proposed in which a reed switch that is turned on and off by an external magnetic field is housed in a package including a permanent magnet that supplies the external magnetic field. That is, the reed switch provided in the capsule endoscope has a structure in which the reed switch is turned on by maintaining the off state and reducing the strength of the external magnetic field in an environment where a magnetic field having a certain intensity or more is applied. For this reason, in the state accommodated in the package, the electric load is not driven. When the capsule endoscope is swallowed, the capsule endoscope is taken out of the package, so that it is separated from the permanent magnet and the capsule endoscope is not affected by the magnetic force, and the driving of the electric load is started. By having such a configuration, the electric load can be prevented from being driven in the state of being accommodated in the package, and after being taken out of the package, the image can be captured by the imaging function of the capsule endoscope and the wireless function. An image signal was being transmitted.

In these drawings, the indwelling device 5 includes a holding unit 55 as a holding unit that holds the capsule endoscope 3 therein, and a coupling unit 56 as a body cavity tissue coupling unit for fixing to the body cavity tissue. And a control device 57 as a body cavity introduction device control means for controlling the operation of the capsule endoscope 3. The holding portion 55 includes a cylindrical tube body 59 having a bottom portion 58 with a bottom at one end. The inner diameter of the tube body 59 is substantially the same as the outer diameter of the body housing of the capsule endoscope 3. The bottom 58 is configured substantially the same as the outer shape of the tip cover housing of the capsule endoscope 3. Thereby, as shown in FIG. 3, the capsule endoscope 3 is accommodated in a cylindrical body 59 of the holding portion 55 so as to be held together with the indwelling device 5 to constitute an in-vivo introduction device placement system.
The coupling portion 56 is composed of two protruding protrusions 60 that are provided on the outer peripheral surface of the cylindrical body 59 and are provided with circular holes that penetrate the front and back surfaces. 61 is provided.

The control device 57 includes a driver board 68 provided below the power supply board 63 and constituting an electromagnet driver 69, and a magnetic body 70, which constitute a second interface (electromagnet).
The magnetic body 70 has a bifurcated shape having magnetic body end portions 70a and 70b. When the capsule endoscope 3 is held by the indwelling device 5, both end portions 70a and 70b are at the same position of the reed switch 14. It is formed so that it may be arranged. A coil K is wound around the magnetic body 70, and current is passed from the electromagnet driver 69 to the coil K to magnetize the magnetic body 70. For example, the magnetic pole N is at the end 70a and the magnetic pole is at the end 70b. S is generated and functions as an electromagnet. Here, when the magnetic body 70 functions as an electromagnet, a magnetic circuit is formed through the electrode of the reed switch 14. When this magnetic circuit is formed, the reed switch 14 is magnetized to generate a magnetic attractive force between the contacts, and the contacts come into contact and turn on. The optical sensor 73 is provided at the tip of the holding portion 55 on the bottom 58 side, and has a function of a switch that detects light irradiated from the outside and enables power supply from the battery 72.
Next, the internal configuration of the control device 57 of the indwelling device 5 will be described with reference to FIG. FIG. 7 is a block diagram showing a circuit configuration of the control device 57 of the indwelling device 5 according to the first embodiment shown in FIG. In FIG. 7, before the capsule endoscope 3 and the indwelling device 5 are swallowed into the subject 1, the control device 57 is activated by irradiating the light sensor (switch) 73 with light from the outside in advance. Later, it is swallowed by the subject 1. When power is supplied from the battery 72, after the system reset by the reset circuit 74 is applied, the controller 75 controls the operation of the electromagnet driver 69 at regular time intervals so that a current flows from the electromagnet driver 69 to the coil K. Thus, the magnetic body 70 is magnetized. Due to the magnetization of the magnetic body 70, a magnetic circuit is formed between the reed switch 14 and a magnetic field is generated, and the contacts of the reed switch 14 come into contact with each other of the capsule endoscope 3 from the power supply unit 15. Power is supplied.
In this embodiment, since the operation of the capsule endoscope 3 cannot be controlled after the intra-body-cavity introduction device indwelling system is swallowed into the subject 1, the indwelling device 5 is activated in advance before swallowing. The indwelling device 5 controls the operation of the capsule endoscope 3 every predetermined time after swallowing, and takes an image of the body cavity by the image sensor and transmits image data by the wireless unit. That is, in this embodiment, the controller 75 is programmed with a command for controlling the operation of the capsule endoscope 3 at regular time intervals, that is, a command for controlling the operation of the electromagnet driver 69 at regular time intervals. Command control is performed such that the above-described operation control is repeated at a fixed time interval of once every minute or hour.
Thus, in this embodiment, when the optical sensor having a switch function detects light, the controller performs drive control of the electromagnet at regular time intervals to turn on the reed switch of the capsule endoscope. Enables power supply and operates the image sensor and wireless unit to image the body cavity and transmit the captured image, so drive the electromagnet to turn on the reed switch at the time required for observation When the observation is not necessary, the electromagnet can be stopped and the reed switch can be turned off, that is, the time interval for operating the image sensor and the wireless unit can be increased. As a result, battery consumption of the capsule endoscope can be reduced. That is, the control device 57 controls the power consumption operation of the capsule endoscope. For this reason, in this embodiment, the photographing time interval can be lengthened, unnecessary image data can be reduced, and the capsule endoscope can be driven for a long time.
In addition, as a configuration of the reed switch, for example, when a magnetic field is applied, the contacts come into contact with each other to be turned off, and when no magnetic field is applied, the contacts are separated from each other to be turned on. In such a configuration, the electromagnet of the indwelling device is driven in the initial state to apply a magnetic field to the reed switch to turn it off, and the electromagnet is controlled to prevent the magnetic field from being applied to the reed switch when necessary. By doing so, it is possible to reduce the battery consumption of the capsule endoscope as in the first embodiment. Some reed switches perform an on / off operation according to a predetermined pattern. In this case, the same effect as in the first embodiment can be obtained by controlling the operation of the electromagnet in accordance with the pattern.
4 is a cross-sectional view showing a modification of the AA cross section of FIG. As shown in FIG. 3, when the bias magnets 77a and 77b are arranged on the inner side surfaces of the magnetic body end portions 70a and 70b of the holding unit 55 of the indwelling device 5 and the electromagnet is not driven, the contacts of the reed switch 14 come into contact with each other. When the electromagnet is driven, the magnetic field passing through the reed switch 14 becomes weak, and the contact of the reed switch 14 may be separated and turned on.
By configuring as in this modified example, it is only necessary to pass an electric current through the electromagnet only when it is desired to operate the capsule endoscope, and the power consumption of the indwelling device can be reduced. Further, the reed switch 14 does not directly control the power supply, but may be configured as a switch for generating an on / off signal in a separately provided power supply control circuit (IC).
Next, the body cavity introduction device placement system according to the second exemplary embodiment will be described.

The external power supply can be terminated at a distance, thereby reducing battery consumption of the capsule endoscope. For this reason, in this embodiment, the photographing time interval can be lengthened, unnecessary image data can be reduced, and the capsule endoscope can be driven for a long time.
Further, in this embodiment, by supplying electric power to the indwelling device from the outside, the operation control of the capsule endoscope can be performed from the outside, and versatility can be improved. In this embodiment, since the capsule endoscope is operated as necessary, the operation of the capsule endoscope suitable for the purpose of placement can be realized by control from the placement device.
FIG. 14 is a cross-sectional view showing the internal configuration of the body cavity introduction device placement system in a state where the capsule endoscope and the placement device according to the third embodiment are combined, and FIG. It is a block diagram which shows the circuit structure of the control circuit of the indwelling apparatus. In FIG. 14, this embodiment is different from the first embodiment in that a permanent magnet 77 is used instead of an electromagnet as the second interface.
That is, in this embodiment, the control device 57 is provided under the power supply board 63 in addition to the first interface including the optical sensor 73 as the light detection means, the reset circuit 74, and the control board 66 constituting the controller 75. A second interface (magnetic material) comprising a driver board 68 that is provided and constitutes the motor driver 76, a motor M that is driven and controlled by the motor driver 76, and a permanent magnet 77 that is connected to the motor M via the shaft 80. And a movable part that moves the magnetic body.
Similar to the first embodiment, the optical sensor 73 is provided at the tip of the holding portion 55 on the bottom 58 side, and functions as a switch that detects light emitted from the outside and enables power supply from the battery 72. Have The shaft 80 has a bifurcated shape, and an N-pole and S-pole permanent magnet 77 is provided at the tip. The shaft 80 is formed such that when the capsule endoscope 3 is held by the indwelling device 5, the permanent magnets 77 at both ends are arranged at the same position of the reed switch 14. The motor M rotates the permanent magnets at both ends of the shaft 80 in the circumferential direction of the capsule endoscope 3. The coupling unit 56 is the same as that in the first embodiment, and thus the description thereof is omitted here.
Next, the internal configuration of the control device 57 of the indwelling device 5 will be described with reference to FIG. In FIG. 15, before the capsule endoscope 3 and the indwelling device 5 are swallowed into the subject 1, the control device 57 is activated by previously irradiating the light sensor (switch) 73 with light from the outside. Later, it is swallowed by the subject 1. When power is supplied from the battery 72, after the system reset is performed by the reset circuit 74, the controller 75 controls the operation of the motor driver 76 at regular time intervals, and the motor M controls the shaft 80 with the capsule endoscope. 3, the permanent magnet 77 is moved to a position where the reed switch 14 is turned on. Due to the movement control of the permanent magnet 77, a magnetic circuit is formed between the reed switch 14 and a magnetic field is generated, and the contacts of the reed switch 14 are brought into contact with each other. Power is supplied from the power supply unit 15 to each part of the mirror 3.
In this embodiment, since the operation of the capsule endoscope 3 cannot be controlled after the intra-body-cavity introduction device indwelling system is swallowed into the subject 1, the indwelling device 5 is activated in advance before swallowing. The indwelling device 5 controls the operation of the capsule endoscope 3 every predetermined time after swallowing, and takes an image of the body cavity by the image sensor and transmits image data by the wireless unit. That is, in this embodiment, a command for controlling the operation of the capsule endoscope 3 at a predetermined time interval is programmed in the controller 75, and the operation control is performed at a constant time interval of, for example, 30 minutes or once every hour.

Since the image sensor and the wireless unit are moved to the position where the state is to be operated and the body cavity is imaged and the captured image is transmitted, the permanent magnet is moved to the position where the reed switch is turned on at the time required for observation. The capsule endoscope can be moved closer to observe the body cavity, and when there is no need for observation, the operation can be controlled so that the permanent magnet is moved away from the reed switch. Mirror battery consumption can be reduced. For this reason, as in the first embodiment, the imaging time interval can be increased, and unnecessary image data can be reduced and the capsule endoscope can be driven for a long time.
FIG. 16 is a cross-sectional view illustrating an internal configuration of the body cavity introduction device placement system in a state where the capsule endoscope and the placement device according to the first modification of the third embodiment are combined. This modified example is different from the third embodiment in that the third embodiment controls the rotation of the permanent magnet 77 in the circumferential direction of the capsule endoscope 3, while the permanent magnet 77 is different from that of the capsule endoscope 3. It is a point to control movement in the longitudinal direction. In order to realize this movement control, in this modification, a pulley 78 connected to a string 79 is disposed on the rotation shaft of the motor, and a shaft 80 connected to the tip of the string 79 is moved in the right direction in the figure. In this way, the permanent magnet at the tip is moved away from the position where the reed switch 14 is turned on. When the motor is stopped, the shaft 80 is moved in the left direction in the figure by the biasing force of the spring 81, and brings the permanent magnet 77 at the tip closer to the position where the reed switch 14 is turned on.
Also in this modification 1, when the light sensor detects light, the controller performs stop control of the motor at regular time intervals, and moves the permanent magnet to a position where the reed switch of the capsule endoscope is turned on. Then, the image sensor and the radio unit are operated to image the inside of the body cavity and transmit the captured image. Therefore, when the observation is necessary, the permanent magnet is brought close to the position where the reed switch is turned on, The body cavity can be observed by operating the mirror, and when there is no need for observation, the operation can be controlled so that the permanent magnet is moved away from the reed switch, and the same effect as in the third embodiment can be obtained. it can.
In addition, as a configuration of the reed switch described in the first embodiment, when the magnetic field is applied, the contacts are brought into an off state and when the magnetic field is not applied, the contacts are separated from each other and turned on. If necessary, move the permanent magnet away from the end of the reed switch so that the permanent magnet is separated from the reed switch contact. If it controls so that it may contact, the same effect can be acquired.

It is sectional drawing which shows the internal structure of the body cavity introduction apparatus indwelling system in the state which couple | bonded the capsule type endoscope and indwelling apparatus concerning Embodiment 4. The fourth embodiment differs from the third embodiment in that an optical sensor 29 as a light detecting means is provided on the electrode substrate 28 of the battery 24 of the capsule endoscope 3 instead of the reed switch 14. The optical sensor 29 has a power switch function. Further, when the capsule endoscope 3 is held by the indwelling device 5, an LED 82 is provided as a light emitting element that emits infrared rays, for example, in the cylindrical body 59 of the holding unit 55 at the same position as the optical sensor 29. The LED is operated by the LED driver 83 of the driver board 68. The LED 82 and the LED driver 83 constitute a second interface, and the optical sensor 73, the reset circuit 74, and the controller 75 constitute a control device 57.
Next, the internal configuration of the control device 57 of the indwelling device 5 will be described with reference to FIG. In FIG. 19, before the capsule endoscope 3 and the indwelling device 5 are swallowed into the subject 1, the control device 57 is activated by previously irradiating the light sensor (switch) 73 with light from the outside. Later, it is swallowed by the subject 1. When power is supplied from the battery 72, after the system reset by the reset circuit 74 is applied, the controller 75 controls the operation of the LED driver 83 at regular time intervals to turn on the LEDs 82. By the lighting control of the LED 82, the optical sensor 29 detects light and is turned on, and power is supplied from the power supply unit 15 to each part of the capsule endoscope 3.
Also in this embodiment, similarly to the third embodiment, the controller 75 performs the command control of repeating the operation control of the capsule endoscope 3 at a constant time interval, whereby the body cavity by the image sensor at every constant time interval. The internal image is captured and image data is transmitted by the wireless unit.

That is, as shown in FIG. 20, when the body cavity introduction device placement system is introduced into the subject 1 while being held by the hood 9 provided at the distal end of the endoscope 8, the light emitted from the endoscope 8 is emitted. Since the optical sensor 73 of the indwelling device 5 detects the detected illuminance, the illuminance of the light detected by the optical sensor 73 is increased after being placed in the body cavity and the endoscope 8 being removed from the body cavity. Will be lowered. Therefore, in this modification, the controller 75 is programmed with a command for capturing and transmitting images at a high rate when the illuminance is high. For example, the capsule endoscope is always turned on, for example, once every 0.5 seconds. In addition, a command for capturing and transmitting an image at a slow rate is programmed at low illuminance, and the above operation control is repeated at a time interval of, for example, once every 30 minutes or once every hour.

In the fourth embodiment, the timing for acquiring the information in the body cavity is controlled by changing the rate of image capturing and transmission, but the rate of the optical sensor having the function of the power switch is not changed without changing the rate. The timing for acquiring information in the body cavity can also be controlled by changing the time interval between on and off, or by changing the interval between image capture and transmission.
As another modification of the fourth embodiment, a magnetic sensor as a magnetic detection means can be provided instead of the optical sensor 73 of the indwelling device 5. In this case, the permanent magnet is brought close to the indwelling device 5 swallowed from the outside of the subject 1, and the magnetism of the permanent magnet is detected by a magnetic sensor having a switch function, as in the fourth embodiment. Since the image sensor and the wireless unit of the capsule endoscope are operated to image the body cavity and transmit the captured image, the same effects as in the fourth embodiment can be obtained.
As another modification, it is possible to provide a wireless device as wireless receiving means instead of the optical sensor 73 of the indwelling device 5. In this case, the controller 75 performs control based on the command signal by transmitting a command signal for control from the external wireless device to the indwelling device 5 and receiving the command signal by the wireless device of the indwelling device 5. Thus, as in the fourth embodiment, the image sensor and the wireless unit of the capsule endoscope are operated to perform imaging in the body cavity and transmission of the captured image, so that the same effects as in the fourth embodiment are achieved. be able to.
