Description

Capsule endoscope device

Technical Field

The present invention relates to a capsule endoscope apparatus, and more particularly, to a capsule endoscope apparatus incorporating an ultrasonic sensor and an optical sensor.

Background

The human digestive system is roughly divided into esophagus, stomach, small intestine and large intestine. Generally, the esophagus and stomach are observed with an upper gastrointestinal endoscope insertable into the distal end of the duodenum, and the large intestine is observed with a large intestine endoscope through which the terminal part of the ileum in the posterior part of the small intestine is observed. However, no endoscope with a complete diagnostic and/or therapeutic method has been established for the small intestine. Therefore, although various radiodiagnostic methods including small intestine barium contrast imaging and CT imaging are applied to the small intestine, the diagnosis rate of small intestine diseases is still low.

In recent years, capsule endoscopes have been actively developed to compensate for these problems. The capsule endoscope can be swallowed through the oral cavity and is divided into a capsule endoscope device using a small-sized camera or a capsule endoscope device using an ultrasonic camera, so that not only the esophagus, the stomach and the small intestine but also the large intestine can be observed. However, the conventional capsule endoscope has a structural defect that the small-sized camera and the ultrasonic camera cannot be simultaneously applied.

Therefore, in the related art, when a capsule endoscope apparatus using a small camera is used, it is difficult to closely adhere to the inner wall of the intestines and stomach in the digestive system, and thus it is difficult to perform close-range imaging, and it is also difficult to image peripheral organs around the intestines and stomach. Therefore, there is an inconvenience that a CT scan or an ultrasonic endoscope using a probe alone is required in order to examine organs around the stomach, such as pancreas.

On the other hand, although a capsule endoscope apparatus to which an ultrasonic camera is applied acquires an ultrasonic image by transmitting and receiving ultrasonic waves, the ultrasonic image is different from an image captured by a small-sized camera and requires a special analysis. That is, it is difficult to accurately derive the examination result without a professional analyst.

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, when reference numerals are given to components in each drawing, the same components are given the same reference numerals as much as possible even in different drawings. In describing the present invention, if it is determined that the detailed description of the related known structure or function will obscure the gist of the present invention, the detailed description thereof will be omitted. The preferred embodiments of the present invention will be described below, but the technical spirit of the present invention is not limited or restricted by the preferred embodiments, and can be variously embodied by a person of ordinary skill in the art.

Fig. 1 is an exploded perspective view of a capsule endoscope apparatus according to a first embodiment of the present invention, and fig. 2 is a view showing an internal structure of the capsule endoscope apparatus according to the first embodiment of the present invention in a sectional form.

A capsule endoscopic device 1 according to a first embodiment of the present invention includes: a housing divided into a first housing 10 and a second housing 20; an optical sensor module 40 built in the first casing 10 side; and an ultrasonic sensor module 80 built in the second case 20.

The housing is divided into a first housing 10 and a second housing 20. In one embodiment, the first casing 10 and the second casing 20 are combined in a state where the parts of the capsule endoscope apparatus 1 are built in the first casing 10 and the second casing 20, respectively, whereby the parts of the first casing 10 and the second casing 20 are electrically connected. In addition, the coupling portion of the first and

second housings

10 and 20 may be maintained airtight by the waterproof member 21.

The first and

second housings

10 and 20 may be manufactured in a sealed structure or a non-sealed structure, as necessary. As an embodiment, it may be made that the first housing 10 is not a sealed structure, and the second housing 20 is a sealed structure to be filled with a liquid or the like for transmitting an acoustic wave signal inside. However, when the ultrasonic sensor module 80 itself is configured as a seal structure, the second housing 20 may not be a seal structure.

According to an embodiment of the present invention, the first housing 10 and the second housing 20 may be used independently, respectively, but it is preferable that after the first housing 10 and the second housing 20 are coupled to form one body, the coupling portion may be subjected to waterproofing treatment by the waterproofing member 21. The lengths of the first and

second housings

10 and 20 may be the same or different, respectively, depending on the parts mounted inside the first and

second housings

10 and 20.

In one embodiment, the first housing 10 may accommodate the optical sensor module 40 mounted on the circuit board 30, the battery 70 for supplying power, and the first magnet 90a, which is a permanent magnet that can adjust the posture and the traveling direction by external magnetic force. In addition, at least a part of the first housing 10 may be formed of a light-transmitting portion 12 made of an optically transparent material. This is to enable the optical sensor module 40 to capture an external image. In the practice of the present invention, the battery 70 may be accommodated in the second housing 20 instead of the first housing 10.

The optical sensor module 40 captures an inner wall of the digestive system in real time or intermittently while the first housing 10 moves in the digestive system of the human body, and outputs image data, and may be an optical sensor such as a CMOS (Complementary Metal Oxide Semiconductor).

The circuit board 30 includes a main substrate 34 for mounting the optical sensor module 40. The primary substrate 34 may be made of a hard material so as to support the optical sensor module 40. The main substrate 34 may be provided with a first connection portion 32 on one side thereof. The first connecting portion 32 may be mounted to the first casing 10 in a manner to cover at least a part of the opening portion of the first casing 10. Also, the first connection portion 32 may be electrically connected with the main substrate 34. In one embodiment, the first connection portion 32 may be formed of a PCB of a hard material.

An auxiliary substrate 36 made of a flexible material may be connected to the other side of the main substrate 34. When the auxiliary substrate 36 is made of a Flexible material such as a Flexible Printed Circuit Board (FPCB), it can be more freely disposed in the first housing 10.

In an embodiment, in the second housing 20, an ultrasonic sensor module 80 for outputting ultrasonic data on a submucosal region of the digestive system and peripheral organs located near the digestive system, and a second magnet 90b, which is a permanent magnet adjustable in posture and traveling direction by an external magnetic force, may be accommodated. The opening of the second housing 20 may be provided with a second connection portion 82 exposed to the outside. In one embodiment, the second connecting portion 82 may be a part of the ultrasonic sensor module 80. Further, the second connection portion 82 may be formed of a circuit board of a hard material. However, in practicing the present invention, the second connector 82 is not necessarily part of the ultrasonic sensor module 80. The second connection portion 82 may be provided separately from the ultrasonic sensor module 80, and then the second connection portion 82 and the ultrasonic sensor module 80 may be electrically connected. At least a portion of the second housing 20 may be formed as an ultrasonic wave transmitting portion 22 such as silicon gel that transmits ultrasonic waves.

In one embodiment, the ultrasonic sensor module 80 may include: a transducer 88; and a reflector 86 for reflecting the ultrasonic waves output from or input to the transducer 88. In addition, the ultrasonic sensor module 80 may further include a motor 84 that rotates a reflector 86 to adjust the output and reflection angle of the ultrasonic waves.

The ultrasonic sensor module 80 outputs ultrasonic data of a surrounding organ located in an area below an inner wall of a digestive system (hereinafter, referred to as "submucosal area") or located around the digestive system in real time or intermittently during the movement of the second housing 20 in the digestive system of the human body. Peripheral organs of the digestive system include pancreas, spleen, kidney, liver, gall bladder, salivary gland, heart, lung, large intestine, etc.

For example, since a pancreas, which is one of peripheral organs, is located near a pylorus, a pyloric antrum, or a bay of a stomach, the optical sensor module 40 may be caused to perform ultra-close range imaging of an inner wall of the stomach opposite to the pancreas to determine whether there is an abnormality, and the ultrasonic sensor module 80 may be caused to perform ultrasonic imaging of a submucosal region of the inner wall opposite to the pancreas to determine a disease.

The ultrasonic sensor module 80 may suitably include a High Voltage (HV) pulse generator, an HV Tx/Rx switch, a vibrator array, a preamplifier (Pre-AMP), a Variable Gain Amplifier (VGA), a Low Pass Filter (LPF), an AD Converter (ADC), and the like (not shown) used in the art, but these are merely examples and are not necessarily limited thereto.

In addition, the first housing 10 or the second housing 20 may incorporate a control section 50 for controlling the capsule endoscope apparatus 1 and a communication section 60 for wireless communication with the outside. Fig. 1 and 2 show that the first casing 10 incorporates a control unit 50 and a communication unit 60. The control unit 50 and the communication unit 60 may be electrically connected to the circuit board 30 after being separated from the circuit board 30, or may be directly mounted on the circuit board 30. However, in implementing the present invention, at least one of the control unit 50 and the communication unit 60 may be incorporated in the second housing 20.

In an embodiment, the control part 50 may control the optical sensor module 40 or the ultrasonic sensor module 80 while being connected to the connection part such that the digestive system and the submucosal region are photographed at the same time or separately. The printed circuit board 30 may be provided with a drive circuit for controlling the optical sensor module 40 or the ultrasonic sensor module 80.

The communication unit 60 may transmit the image data and the ultrasonic data of the optical sensor module 40 to an external device (not shown) under the control of the control unit 50.

The communication unit 60 may use a galvanic coupling (RF) method or an RF communication technique requiring an antenna, and may support one-way wireless communication or two-way wireless communication, and the communication unit 60 may be formed of one or more Application Specific Integrated Circuits (ASICs).

In the current coupling method, each of the signal electrode (+) and the ground electrode (-) of the transceiver is attached to a human body, and a signal is transmitted by a change in an electric field caused by a potential difference between the two electrodes.

In addition, the communication unit 60 may transmit an operation control signal for controlling the operation of the optical sensor module 40 and/or the ultrasonic sensor module 80, which is output from the external device, to the control unit 50 after receiving the operation control signal. Here, the operation control signal may include, for example, a signal for controlling the optical sensor module 40 and the ultrasonic sensor module 80 to perform photographing simultaneously or photographing sequentially.

Fig. 3(a) is an enlarged view of a portion of fig. 2(a), and fig. 3(b) is a perspective view of a coupling portion of the first housing 10 and the second housing 20.

An annular extension portion 24 having a step and extending with a reduced diameter is formed at the second housing 20, and a recessed groove portion 26 is formed on an outer circumferential surface of the extension portion 24. Accordingly, a projection 16 projecting radially inward is provided on the first housing 10. When the first and

second housings

10 and 20 are coupled, the extension portion 24 is inserted into the inner side of the first housing 10, and the protrusion portion 16 is inserted into the groove portion 26 to couple the first and

second housings

10 and 20. The groove portions 26 and the protruding portions 16 may be provided in plurality in the circumferential direction.

The waterproof member 21 is provided at the coupling portion of the first and

second cases

10 and 20, so that airtightness can be maintained when the first and

second cases

10 and 20 are coupled. In one embodiment, the waterproof member 21 may be an O-ring (O-ring) formed on the extension portion 24. In other embodiments, the waterproof member 21 may be formed by applying a waterproof adhesive to the coupling portion of the first casing 10 and the second casing 20 to form a waterproof adhesive layer (not shown). Alternatively, waterproofing may be achieved by an appropriate method such as welding (e.g., thermal welding or ultrasonic welding) of the joint portion without using an O-ring or a waterproof adhesive layer.

In the present invention, the recess portion 26 may be provided on the inner surface of the first housing 10, and the protrusion 16 may be provided to protrude outward from the extension portion 24 of the second housing 20.

In the embodiment of fig. 4, an "L" -shaped guide groove 28 is formed on the outer peripheral surface of the extension portion 24 of the second housing 20, and the guide projection 18 is formed on the first housing. When the first housing 10 and the second housing 20 are coupled, the guide protrusion 18 is inserted along the guide groove 28 in the length direction of the capsule endoscopic device 1. Thereafter, when the second housing 20 rotates relative to the first housing 10, the guide projection 18 rotates along the outer circumferential direction guide groove 28 of the extension portion 24. With this configuration, the first casing 10 and the second casing 20 are connected. The guide groove 28 and the guide projection 18 may be provided in plurality in the circumferential direction. In addition, the guide groove 28 may be provided on the inner side surface of the first housing 10, and the guide protrusion 18 may be provided to protrude outward at the extension portion 24 of the second housing 20.

Fig. 5 is an explanatory view of mounting a circuit board inside a 1 st housing in a capsule endoscope apparatus according to a first embodiment of the present invention.

Referring to fig. 5 and 1, a substrate fixing portion 14 may be formed on an inner circumferential surface of the first housing 10 in a longitudinal direction. The substrate fixing portion 14 may be formed in a groove shape along the longitudinal direction. The main substrate 34 of the circuit board 30 is slidably coupled along the substrate fixing portion 14, and thus, may be mounted on the first housing 10.

Fig. 6 is a diagram showing a structure of a first connecting portion of a first housing for electrically connecting the first housing and a second housing in a capsule endoscope apparatus according to a first embodiment of the present invention. Fig. 7(a) is a view showing a first connecting portion of a first housing for electrically connecting the first housing and a second housing in a capsule endoscope apparatus according to a first embodiment of the present invention, and (b) is a view showing a second connecting portion of the second housing.

In the present invention, it is characterized in that the first and

second housings

10 and 20 are electrically connected at the same time when the first and

second housings

10 and 20 are coupled. With this structure, the electronic parts of the first and

second housings

10 and 20 can be electrically connected without requiring additional wiring work or other connection by a connector.

The first housing 10 has a first connection portion 32 on an open surface thereof, and the first connection portion 32 has a first connection terminal 33 formed thereon. The second case 20 has a second connection portion 82 on an open surface thereof, and a second connection terminal 83 is formed on the second connection portion 82. When the first housing 10 and the second housing 20 are coupled, the first connection terminal 33 and the second connection terminal 83 form a contact electrical connection. In an embodiment, one of the first connection terminal 33 or the second connection terminal 83 may be formed in the form of a pogo pin (pogo pin) supported by a spring. Further, in other embodiments, one of the first connection terminal 33 or the second connection terminal 83 may be formed in the form of a protruding connection pin.

The capsule endoscope apparatus 1 will be explained as being controlled by an external device (not shown) to capture an image of the inside of a human body and generate ultrasonic data.

The external device may include a magnetic controller that controls the first and second magnets 90a and 90b, which are permanent magnets, respectively contained in the first and

second housings

10 and 20 using external magnets generating external magnetic force, and a monitoring apparatus, and may control the position, posture, and traveling direction of the first and

second housings

10 and 20 constituting one body.

In terms of improving the accuracy and reliability of controlling the posture and movement of the capsule endoscope apparatus 1 by the magnetic controller, in the capsule endoscope apparatus 1 according to the present invention, as shown in fig. 1 or 2, the first magnet 90a and the second magnet 90b may be preferably provided at both side ends in the internal space of the capsule endoscope apparatus 1.

The examiner brings the magnetic controller as an external device close to the abdomen of the patient who swallows the capsule endoscope apparatus 1, and then adjusts the magnetic controller in order to control the position or posture of the capsule endoscope apparatus 1. The capsule endoscope apparatus 1 moves in the digestive system and images the inner wall to be imaged or the submucosal region of the inner wall to be imaged by the optical sensor module 40 and/or the ultrasonic sensor module 80. The image information and the ultrasonic data are transmitted to an external monitoring device (not shown) through the communication unit 60, and can be confirmed by the monitoring device.

The capsule endoscope apparatus 1 can be moved close to the gastrointestinal inner wall of the digestive system by the external magnetic force of the external apparatus, and the examiner can judge the position close to the digestive system (for example, esophagus, stomach) while seeing the image corresponding to the sensor-captured data displayed on the external device, and operate the external device to move the capsule endoscope apparatus 1.

At the inner wall of the intestines and stomach near the digestive system, the capsule endoscope apparatus 1 maintains or turns off the operation of the optical sensor module 40 by the operation control signal, and turns on the ultrasonic sensor module 80.

Then, the capsule endoscope apparatus 1 is brought into close contact with the inner wall of the intestines and stomach as much as possible by the external magnetic force of the external device. When a predetermined ultrasonic frequency is transmitted from an external device to the control part 50 through the transceiver 60, the control part 50 controls the ultrasonic sensor module 80 accommodated in the second housing 20 to generate a corresponding frequency.

The ultrasonic sensor module 80 generates a vibration wave corresponding to an ultrasonic frequency, receives the vibration wave reflected from the inner wall, performs processing such as amplification and digital conversion on the signal, and outputs ultrasonic data, which is transmitted to an external device through the transceiver 60. The examiner can monitor an ultrasonic image corresponding to a portion of the digestive system (e.g., pancreas) through the external device.

Fig. 8 is an exploded perspective view of a capsule endoscope apparatus according to a second embodiment of the present invention, and fig. 9 is a view showing an internal structure of the capsule endoscope apparatus according to the second embodiment of the present invention in a sectional form.

The capsule endoscope apparatus 100 according to the second embodiment includes: a first housing 110 having a light-transmitting portion 112 formed thereon; a second case 120 coupled to the first case 110 and formed with a silicon transmissive part 122; an optical sensor module 140 and an ultrasonic sensor module 180 disposed inside the coupled first and

The optical sensor module 140 may be mounted on the main substrate 134 of the circuit board 130. The main substrate 134 is slidably inserted and fixed to the substrate fixing portion 114 formed in the first housing 110. A flexible auxiliary substrate 136 may be connected to one side of the main substrate 134.

The capsule endoscope apparatus 100 according to the second embodiment is different from the capsule endoscope apparatus 1 of the first embodiment in that it is extended to the outside of the first housing 110 in a state where the main base plate 134 is coupled to the first housing 110. That is, a portion of the main substrate 134 is provided in a form extended to the inside of the second case 120. In one embodiment, a structure for slidably fixing the main substrate 134 may be formed inside the second housing 120 corresponding to the substrate fixing portion 114.

By configuring the main substrate 134 to extend from the first casing 110 to the inside of the second casing 120, the area of the main substrate 134 can be secured, and the mounting area of the electronic components can be increased. Therefore, it is sufficient to mount the electronic devices for the control section 150 and the communication section 160 on the main substrate 134.

In addition, referring to fig. 8, the ultrasonic sensor module 180 is shown to include a reflector 186 and a transducer 188, and a motor 184 for rotating the reflector 186 is exposed to the outside of the ultrasonic sensor module 180. However, the configuration of the ultrasonic sensor module 180 including the motor 184 may be the same as the ultrasonic sensor module 80 of the first embodiment.

In one embodiment, the ultrasonic sensor module 180 may be mounted on the main substrate 134.

However, similar to the first embodiment, the ultrasonic sensor module 180 may be accommodated inside the second housing 120 in a state of being coupled to the second housing 120. The ultrasonic sensor module 180 is prepared in a state of being coupled inside the second housing 120, and when the first housing 110 and the second housing 120 are coupled, as shown in fig. 9, a portion of the main substrate 134 may be positioned below the ultrasonic sensor module 180.

When the first case 110 is provided with the optical sensor module 140, and the first case 110 and the second case 120 are coupled to each other with the electronic components separately provided to the first case 110 and the second case 120, as in the case where the second case 120 is provided with the ultrasonic sensor module 180, the first case 110 and the second case 120 can be electrically connected to each other.

Referring to fig. 10, the main substrate 134 includes a first connection terminal 132 at one end thereof. Accordingly, the second housing 120 is provided with a second connection terminal 182 which is in contact with the first connection terminal 132. When the first connection terminal 132 and the second connection terminal 182 are coupled, they may be located at faces facing each other.

When the first and

second housings

110 and 120 are coupled, the main substrate 134 is inserted into the inside of the second housing 120, and the first connection terminal 132 contacts the second connection terminal 182 provided to the second housing 120, thereby achieving electrical connection.

The above description is merely an exemplary description of the technical idea of the present invention, and a person of ordinary skill in the art to which the present invention pertains may make various modifications, alterations, and substitutions without departing from the essential characteristics of the present invention.
