Description

[Technical field]

[0001] The present invention relates to a capsule endoscope. [Background technology]

[0002] Due to its high reliability and safety, the capsule endoscope has become an effective equipment for gastrointestinal disease diagnosis and has been highly recognized in the international medical device field. The capsule endoscope includes a CMOS image sensor, an optical system, a battery, a transmission circuit, an antenna, etc. An image of the human gastrointestinal tract is formed on the surface of the CMOS image sensor through the optical system, and the optical signal is converted into an electrical signal by the CMOS image sensor, and the electrical signal is modulated and amplified through the transmission circuit and transmitted through the antenna. The information is received by an external receiving device and displayed on a display device. In the peristaltic state of the human gastrointestinal tract without pain or wounds, a doctor can diagnose gastrointestinal diseases on the subject based on the image displayed on the display device.

[0003] Currently, capsule endoscopes such as Given's PillCam series, Olympus' EndoCapsule 10 series, and IntroMedic's MirоCam series are on the market, but because they move uncontrollably in the stomach, they are mainly used for intestinal examinations where there is no need to control their movement.On the other hand, Ancon's NaviCam series capsule endoscopes can perform medical examinations in the stomach under the action of an external magnetic field.

[0004] The internal heat management of the capsule endoscope has an important impact on the inspection time, imaging effect, control accuracy, etc. Due to the volume limitation of the capsule endoscope, the internal heat management method of the capsule endoscope still needs to be improved.

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understandable, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, if not inconsistent, the embodiments and features in the embodiments of the present application may be combined with each other.

[0020] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein, and therefore the scope of protection of the present invention is not limited by the specific embodiments disclosed below.

[0021] As shown in Figs. 1 to 13, the capsule endoscope according to the present invention includes a housing (1). The housing (1) includes a main body (101), a first housing end (102), and a second housing end (103). The main body (101) of the capsule endoscope is cylindrical, the first housing end (102) is semi-elliptical, and the second housing end (103) is also semi-elliptical. The three are combined to form a capsule-shaped endoscope, which is convenient for swallowing and examination. The capsule endoscope further includes an image acquisition module (2) provided in the first housing end (102), a circuit processing module (3) provided in the main body (101), and an information transmission module including an antenna (401). The antenna (401) is fixed to the inner wall of the main body (101), or to the inner wall of the main body (101) and the inner wall of the second housing end (103). The antenna (401) is connected to an image acquisition module (2) and / or a circuit processing module (3).

[0022] The circuit processing module (3) is composed of one or more of the following: a processor, an image accelerator, a power management IC (PMIC), an acceleration sensor, a six-axis sensor, a light sensor, and an infrared sensor.

[0023] The capsule endoscope also includes a battery (6) that supplies power to each unit of the capsule endoscope and is controlled by a power supply IC. The antenna (401) is attached to the inner wall of the housing of the capsule endoscope. Specifically, the antenna (401) may be fixed only to the inner wall of the main body (101), or may be fixed simultaneously to the inner wall of the main body and the inner wall of the second housing end (103) facing the image acquisition module (2). The antenna (401) has a protruding structure.

[0024] The antenna (401) has a heat conduction function, and based on the basic formula of heat conduction "Q = K x A x ΔT / ΔL", the magnitude of heat conduction Q is proportional to the heat conduction coefficient K and the heat transfer area A, and inversely proportional to the distance ΔL. The higher the heat conductivity, the larger the heat transfer area, and the shorter the transmission distance, the higher the heat conduction energy and the easier it is to lose heat. When the antenna (401) is fixed to the inner wall of the main body (101) and the inner wall of the second end part (103) of the housing facing the image acquisition module (2) at the same time, the antenna (401) separately covers the inner wall of the second end part (103) of the housing and the area of ​​the installed antenna (401) is larger than when the antenna (401) is fixed only to the inner wall of the main body (101), so the area of ​​the installed antenna (401) is larger, and the area of ​​the heat conduction is larger and the heat conduction effect is better.

[0025] 2 is a structural schematic diagram of an antenna of a capsule endoscope. As shown in FIG. 2, the antenna (401) includes an antenna arm (4011) fixed to the inner wall of the main body (101), or to the inner wall of the main body (101) and the inner wall of the second housing end (103).

[0026] The antenna arm (4011) is the main body structure of the antenna (401). Specifically, as shown in Fig. 3, the entire antenna is divided into the antenna arm (4011) and a bottom antenna (4012). The bottom antenna (4012) is disposed in the second end portion (103) of the housing facing the image acquisition module (2), and the antenna arm (4011) is connected to the bottom antenna (4012). The bottom antenna (4012) is provided with a power supply port (4013) for connection to the circuit processing module (3).

[0027] The antenna (401) may be made in a helical shape and is attached to the inside of the capsule housing by rotation. A helical antenna has a tendency to expand outwards. The capsule housing limits said tendency and ensures that the antenna (401) and the housing (1) form a stable and fixed structure.

[0028] The shape of the antenna arm (4011) can be one or a combination of a double arm helical antenna, a helical antenna, an inverted L-shaped antenna, a T-shaped antenna, an umbrella antenna, a cage antenna, a rectangular antenna, a V-shaped antenna, a diamond antenna, a fishbone antenna, a disc taper antenna, and a double taper antenna.

[0029] In a preferred embodiment, the antenna arm (4011) is a double-arm helical antenna, as shown in Fig. 3. The antenna arm (4011) is arranged in a spiral shape and matches the inner wall of the capsule housing so that it is attached relatively flatly to the inner wall of the capsule housing. When a copper foil is used as the antenna, it can contact the inner wall over a wide surface and be attached to the inner wall, while increasing the contact area with the inner wall.

[0030] The antenna arm (4011) is made of copper foil with a width of 1 mm to 10 mm. Copper has high thermal conductivity and can quickly transfer heat to the entire antenna arm (4011). The thickness of the antenna arm (4011) is 0.1 mm to 1 mm.

[0031] FIG. 3 shows a case where the antenna arm (4011) is provided so as to go around the inner wall of the housing of the capsule endoscope. FIG. 2 is a side view of a case where the antenna arm (4011) is installed so as to go around regularly in a spiral on the inner wall of the housing of the capsule endoscope. The antenna arm (4011) has a continuous structure as a whole, but the present invention is not limited thereto. As can be seen from FIG. 2, when the antenna arm (4011) is arranged so as to go around regularly on the inner wall of the housing of the capsule endoscope, the antenna arm (4011) can be considered to include a plurality of antenna arm (4011) portions. There is a gap between the plurality of portions of the antenna arm (4011).

[0032] The antenna arm (4011) is connected to the image acquisition module (2) and / or the circuit processing module (3). The antenna arm (4011) is connected to the image acquisition module (2) and / or the circuit processing module (3) via a heat conducting wire (not shown). The heat conducting wire may be a metal wire or the like. The information transmission module of the capsule endoscope includes an antenna (401) consisting of the antenna arm (4011) and a radio frequency circuit module (not shown). In the operation mode, an image of the digestive tract is acquired by the imaging module (201) and transmitted to the circuit processing module. The image data processed by the circuit processing module (3) is finally transmitted to the extracorporeal image display device via the radio frequency circuit board and antenna (401) in the information transmission module.

[0033] The antenna arm (4011) is connected to the image acquisition module (2) and / or the circuit processing module (3) via a heat conducting wire (not shown). This allows the heat of the image acquisition module (2) and / or the circuit processing module (3) to be rapidly conducted to the antenna arm (4011). Since the antenna arm (4011) is made of a metal material and has good thermal conductivity, the heat transmitted from the image acquisition module (2) and / or the circuit processing module (3) can be uniformly conducted to the inner wall of the capsule housing. The larger the area coverage of the antenna arm (4011), the better the heat conduction effect and the more uniform the heat transfer. Considering the necessity of the actual operation of the capsule endoscope, the area coverage of the antenna arm (4011) is 10% to 85%, and preferably 20% to 45%.

[0034] Since the antenna arm (4011) does not cover the entire inner wall of the capsule housing, heat can be transferred to the inner wall of the capsule housing where the antenna arm (4011) is laid out. However, since there are gaps between the multiple antenna arm (4011) portions, in the gaps where the antenna arm (4011) is not installed, the heat transferred to the antenna arm (4011) cannot be diffused efficiently, which is likely to lead to heat accumulation.

[0035] In this embodiment, the antenna arm (4011) is packaged using an insulating heat conductive material, and the insulating heat conductive material (5) is applied to the surface of the antenna arm (4011). Also, the insulating heat conductive material (5) is applied to the inner wall surface of the main body part (101) that is not covered by the antenna arm (4011), or to the inner wall surface of the main body part (101) and the inner wall surface of the second housing end part (103).

[0036] For clarity, Fig. 2 shows the insulating thermally conductive material (5) applied to the inner wall surfaces of the main body portion (101) that are not covered by the antenna arm (4011), or to the inner wall surfaces of the main body portion (101) and the inner wall surfaces of the second housing end portion (103). In reality, the surface of the antenna arm (4011) is also covered with the insulating thermally conductive material.

[0037] 4 and 5 are schematic cross-sectional views of the main body (101) of a capsule endoscope. As shown in Fig. 4, the surface of the antenna arm (4011) is covered with an insulating heat conductive material (5), and the inner wall surface of the main body (101) that is not covered with the antenna arm (4011) and the inner wall surface of the second housing end (103) (only the inner wall surface of the main body 101 is shown in Fig. 3) are coated with the insulating heat conductive material (5). After the insulating heat conductive material (5) is applied, the inner surface of the main body (101) or the inner surfaces of the main body (101) and the second housing end (103) have a smooth structure with a uniform height without any protrusions.

[0038] As shown in Fig. 5, after the insulating heat conductive material (5) is applied, the inner wall surface of the main body part (101) may be a non-smooth surface, but the present invention is not limited thereto. Figs. 4 and 5 only show the inner wall of the main body part (101) as an example, but the second housing end part (103) may be the same, and will not be described further here.

[0039] The insulating and heat-conductive material (5) is in close contact with the antenna arm (4011) and can rapidly conduct heat received by the antenna arm (4011) having a heat dissipation function to the entire capsule housing, including the gap between the antenna arms (4011). The insulating and heat-conductive material (5) has a thickness of 0.01 to 0.1 mm.

[0040] In another embodiment, as shown in Fig. 6 and Fig. 7, a heat-retaining material layer 1401 may be further provided between the antenna arm (4011) and the capsule housing. The heat-retaining material layer (1401) can quickly transfer heat received from the image acquisition module (2) and / or the circuit processing module through the antenna to the entire capsule housing to prevent localized high temperatures, and can retain heat inside the capsule instead of releasing the heat to the outside through the housing, thereby collecting heat inside the capsule and extending the battery usage time. The heat-retaining material layer (1401) can include insulating materials with poor thermal conductivity, such as nano-insulation film, PFT film, polyester film, and polyimide film, and the present invention is not limited to these materials.

[0041] As mentioned above, the heat generated in the image collection module and the circuit processing module can be transferred to the antenna arm (4011) because the image collection module and the circuit processing module are connected to the antenna arm (4011) via a heat conductive wire.

[0042] In a capsule endoscope according to an embodiment of the present invention, as shown in Fig. 8, a thermally conductive plate (7) is provided between the antenna arm (4011) and the image acquisition module (2) and the circuit processing module (3). The antenna arm (4011) is connected to the image acquisition module (2) and the circuit processing module (3) via the thermally conductive plate (7). The thermally conductive plate (7) increases a thermal path for transferring heat from the image acquisition module (2) and the circuit processing module (3) to the antenna arm (4011), allowing the heat to be transferred to the antenna arm (4011) more efficiently.

[0043] The image collection module (2) includes an imaging module (201) and an illumination module (202). As shown in Fig. 9, the antenna arm (4011) is connected to the imaging module (201) and / or the illumination module (202) via a thermally conductive plate (7).

[0044] As described above, since heat is accumulated inside the capsule instead of being released to the outside through the housing, the battery usage time can be extended. In order to supply heat to the battery for use, in one embodiment of the present invention, as shown in Fig. 10, a heat conductive plate (7) is provided between the battery (6) and the antenna arm (4011) of the capsule-type endoscope. By connecting the antenna arm (4011) to the battery (6) through the heat conductive plate (7), the heat received by the antenna arm (4011) can be directly transferred to the battery (6) for use in the battery, thereby extending the battery usage time.

[0045] Furthermore, a heat storage material (9) is provided around the battery (6). As shown in Fig. 10, the heat of the antenna arm (4011) is introduced and stored in the heat storage material (9) via the heat conductive plate (7), so that the heat can be slowly released during the long-term examination of the capsule endoscope and the battery can be maintained to operate at an effective operating temperature. The heat of the antenna arm (4011) is generated from the image acquisition module (2) and the circuit processing module (3) and is transferred via the heat conductive plate (7).

[0046] The material of the aforementioned heat conductive plate (7) may include an insulating material with good thermal conductivity. In one embodiment, the heat conductive plate (7) is connected to the insulating heat conductive material (5) provided on the surface of the antenna arm (4011), and can be connected to the antenna arm (4011) through the insulating heat conductive material (5).

[0047] The heat conductive plate (7) can be made of a material with high thermal conductivity, such as a heat conductive adhesive, a heat conductive insulating sheet, or heat conductive silica gel.

[0048] Optionally, the number of the thermally conductive plates (7) connected to the battery (6) is two, three, four or more. Compared with a single thermally conductive plate (7), multiple thermally conductive plates (7) can conduct heat faster, and can quickly and directly transfer the heat received by the antenna arm (4011) to the battery (6) for use in the battery and to extend the service life of the battery.

[0049] Although the capsule endoscope has a small volume, its structure is very complicated, and the heat generated during its operation is difficult to dissipate quickly. By conducting the heat to the capsule housing through the antenna, it is possible to promote the heat dissipation and improve the heat management ability. The material of the capsule housing is usually PC (polycarbonate), PMMA (acrylic), optical polyester resin, etc. These materials are all resins and have relatively good plasticity. The above-mentioned antenna arm (4011) can be integrally molded with the main body case (1011) during manufacturing. That is, after the manufacturing of the antenna arm (4011) is completed, it is injection molded to form the main body of the capsule endoscope. The circuit processing module (3) of the above-mentioned capsule endoscope and the corresponding inner wall of the main body (1011) are respectively provided with connectors (4014), as shown in FIG. 11. In the manufacturing and assembly process, the circuit processing module (3) is pushed into the housing and the two connectors (4014) are connected, thereby realizing an electrical connection that meets the radio frequency requirements of the capsule endoscope. The aforementioned connector (4014) preferably employs contacts that are easy to machine to ensure a valid electrical connection.

[0050] In order to extend the flight time of the capsule endoscope, a wireless charging module is installed in the capsule endoscope. The gastrointestinal examination is controlled by cooperating with the capsule endoscope using an external magnetic control device. At this stage, wireless charging is possible, and after completing the stomach examination, the capsule endoscope enters the intestine to perform the intestinal examination under the natural peristalsis of the gastrointestinal tract, and finally is discharged from the body. The capsule endoscope takes a long time to perform the intestinal examination, which is much longer than the time it stays in the stomach, but wireless charging can only be performed during the stomach examination, and wireless charging cannot be performed in the intestine. Therefore, the problem that the battery of the capsule endoscope does not have enough flight time during the intestinal examination still exists. In addition, the wireless charging module generates heat during operation. If the heat in this part is not controlled, the local temperature of the capsule endoscope housing is too high, i.e., heat is accumulated, which may cause discomfort to the patient.

[0051] In another embodiment, as shown in Fig. 12, in order to solve the problem of the local temperature of the endoscope housing being too high, a wireless charging module (10) is installed at the second end (103) of the housing and electrically connected to the circuit processing module (3). The wireless charging module (10) stores the obtained electric energy in the battery (6) through the circuit processing module (3). A thermal conductive plate (7) is used to connect the antenna arm (4011) and the wireless charging module (10). The heat generated during the operation of the wireless charging module (10) is quickly transferred to the antenna arm (4011) through the thermal conductive plate (7), realizing the heat conduction and avoiding the accumulation of heat.

[0052] In another embodiment, in order to solve the problem of insufficient battery life, as shown in FIG. 13, a wireless charging module (10) is provided in the second end of the housing (103) and electrically connected to the circuit processing module (3). The wireless charging module (10) stores the obtained electric energy in the battery (6) through the circuit processing module (3). A heat storage material (9) is provided around the battery (6). A heat conductive plate (7) is used to connect the wireless charging module (10) and the heat storage material (9). The heat generated during the operation of the wireless charging module (10) enters the heat storage material (9) through the heat conductive plate (7). After the capsule endoscope enters the intestinal tract, it takes several hours of independent photography, and the heat storage material (9) slowly releases heat to activate the battery (6), which can maintain the battery at a higher operating temperature and extend the operating time of the battery while avoiding the problem of heat accumulation causing discomfort to the patient.

[0053] The battery (6) is a silver oxide battery, or a secondary battery that can be used for both silver oxide battery and wireless charging. Preferably, one silver oxide battery and one lithium battery are used, and power is first supplied from the lithium battery during normal stomach examination. After stomach examination is completed, the extracorporeal magnetic control device wirelessly charges the capsule endoscope, and after the lithium battery is fully charged, further examination of the intestinal tract is performed. Compared to using two silver oxide batteries, the wireless charging method based on the combination of one silver oxide battery and one lithium battery can provide a longer flight time.

[0054] As shown in FIG. 1, the capsule endoscope of the present invention includes a permanent magnet (8) connected to the housing. The permanent magnet (8) provides magnetism to the capsule endoscope, and can adjust the position, posture, and direction of the capsule endoscope in cooperation with the external magnetic control device. Optionally, a second permanent magnet (not shown) is provided in the second housing end (103). The second permanent magnet is cylindrical or spherical, and is preferably an elliptical sphere concentric with the second housing end (103). The elliptical sphere permanent magnet can be closely attached to the inner wall of the second housing end (103). The permanent magnet (8) is adjacent to the first housing end (102), and the second permanent magnet is adjacent to the second housing end (103). The two permanent magnets can balance the weight of the capsule endoscope, and in cooperation with the external magnetic control device, generate two magnetic moments to accurately adjust the position, posture, and direction of the capsule endoscope.

[0055] The present invention achieves effective thermal management by quickly conducting heat generated by the image acquisition module and / or the circuit processing module, etc. to the antenna arm, distributing the heat evenly through the antenna arm and reducing localized heat accumulation, or by using a heat storage material to accumulate excess heat near the battery and slowly release it, thereby optimizing the battery's discharge capacity, thereby avoiding patient discomfort caused by excessive temperatures.

[0056] The above description is merely a preferred embodiment of the present invention, and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
