Field of the Invention This invention relates to a capsule endoscope and a capsule internal vision system, and in particular, the present invention relates to a capsule endoscope and an capsule internal vision system having an expandable volume . > [Prior Art] Endoscopy is an effective and commonly used tool in the diagnosis and treatment of digestive tract diseases. Conventional endoscopes provide a photographic lens at the front end of the endoscope catheter and feed the photographic lens along with the endoscope catheter into the digestive tract via the patient's mouth or anus. There are electronic circuits and light in the flashlight tube. The external machine can provide an illumination source to the photographic lens through the optical fiber. The image captured by the photographic lens can be transmitted back to the external machine via fiber optics or electronic circuitry. Because the digestive tract has a considerable length and oil-folding configuration, it is difficult for the endoscope catheter to advance along the digestive tract. At present, the endoscopic gas can be used from the oral cavity to the anterior segment of the small intestine, or from the anus to the end of the large intestine, without the depth of the middle part of the small intestine. In addition, the endoscopic catheter will pull and pull the digestive tract when it advances in the digestive tract. This often causes great pain in the patient to be examined, and the endoscopic examination of the digestive tract is a fearful path. ~ Ding a viewing Xin a; - Capsule endoscopic mirror, can be used to enter the human body (4) the path of the disease, and rely on the continued movement of the intestines to advance in the path. The capsule endoscope includes an image sensor, a wireless transmitter small battery' and is integrated into a capsule shell approximately 26 cm long and diameter U. The small battery supplies the image sensor and the wireless transmitter to work. The image sensor is used to capture the image of the intestinal wall, and the image of the intestine wall taken is transmitted to the outside by the wireless transmitter after being converted into digital information. Control device. Since the small intestine having a relatively small inner diameter of the large intestine is first passed, the size of the capsule endoscope must be designed to fit the inner diameter of the small intestine and not too large. However, this design causes the capsule endoscope to be unable to restrain the capsule endoscope in a fixed spatial orientation when it enters the large intestine with a larger inner diameter because of loosening the large intestine wall. Therefore, the capsule endoscope is prone to roll in the large intestine, and it is impossible to keep the lens in a consistent photographing direction, which often causes image tracking to be difficult. In addition, since the volume of the capsule endoscope is insufficient to fully open the large intestine wall, the intestinal wrinkles may cause a dead angle of imaging, and it is difficult to perform the inspection of the capsule wall. In view of the increasing incidence of colorectal cancer in the world in recent years, if the above-mentioned difficulties can be overcome and the capsule endoscope can be tested for the large intestine, it is possible to provide another comfortable method for the test subject. In this way, the patient's willingness to test can be improved, and the malignant development of the large intestine tumor can be reduced. [Invention] Accordingly, it is an object of the present invention to provide an expandable capsule endoscope to solve the problems of the prior art. ▲ According to a specific embodiment, the expandable capsule endoscope comprises an endoscope power beam assembly, an expandable structure, and an expansion function module. The endoscope function module 201127336 is used to capture images from the expandable capsule endoscope. The expandable structure covers the outside of the endoscope functional module. The expansion function module is disposed in the expandable structure and is configured to control the expansion of the expandable structure according to an expansion start signal. σ y Another aspect of the present invention is to provide an expandable capsule internal vision system to solve the problems of the prior art. According to a specific embodiment, the expandable capsule internal vision system comprises an external helium control device and an expandable capsule endoscope. The external control device has a remote emission unit remote control transmitting unit for transmitting an expansion activation signal. The expansion capsule endoscope has an endoscope function module, an expandable structure and an expansion device. The endoscope function module is used for taking an image outside the capsule endoscope. The expandable structure covers the axis mirror Wei Xiang. The hetero-functional module uses ^ to receive the expansion start signal, and according to the expansion start signal, it can control the expandable service, and the α-shaped expansion service. In summary, according to the present invention, the daily expandable capsule (four) mirror can be used, The volume of the control signal is expanded. After the _expandable capsule endoscope reaches the big face, the external fingering device sends an I expansion control signal to make the capsule endoscope expand moderately. Thereby, the expandable capsular endoscope Can = open the big depreciation to read the details of the image, while avoiding rolling in the wall and keeping the lens shooting direction - the nature, making the location of the image is easy to trace. About the advantages and spirit of the invention can be as follows invention The details and the drawings are further understood. 201127336 [Embodiment] An inflatable capsule endoscope and a system thereof are provided for a tatse (four) image. The expandable capsule endoscope of the present invention The specific embodiments of the system and the charging system are disclosed as follows: 眚r 考图—and FIG. 2, and FIG. 2 are schematic diagrams showing a specific expansion capsule internal vision system 1 according to the present invention, and FIG. 2 is implemented according to the present t 1 . Example of the functional block of the expandable capsule internal vision system 1 (4) 丨L ^ bulging capsule internal view system 1 comprises an expandable capsule endoscope 2 and an external 2 2 3 3. The expandable capsule endoscope 2 years old to include internal view The mirror function module, and 21, the expansion function module 22 and the expandable structure 23. The mirror mirror function group 21 is used to provide an expandable rubber rib mirror 2 image 撷=wide, which includes an image sensing unit buckle, The battery sensing unit 211 mainly includes an optical lens, an optical inductance=211b, and an image processing circuit 2Uc. The front end of the expandable capsule endoscope 2: transparent dome 2& So that the surrounding image can enter the expandable capsule U. Optical lens 211a is disposed at the front end of the expandable capsule endoscope 2, and I rotates the image of the image onto the photo-component 。. The sensing element 2llb converts the image into a current signal, and the image processing electric stepping mountain will The current signal is processed into a digital image. Finally, the digital image is transmitted to the external control device 3 via the wireless transmitting circuit 213. The battery 212 is used to supply power for all components of the expandable capsule endoscope 2. Expandable Lin 23 The county-Civil-to-air sac is not designed to be smooth and has no sharp corners, and its shot is biocompatible. In the unexpanded other 'expandable structure, the 23 series is flat and collapsed to cover the endoscope function mode. On the outer side of the group 201127336 21, only the transparent dome 2a of the front end of the expandable capsule endoscope 2 is exposed. The expandable structure 23 forms a closed space inside, and can be filled by a filling substance and expanded to a suitable size to expand The inner wall of the large intestine is wrinkled and prevents the expandable capsule endoscope 2 from rolling in the large intestine. In practical application, since the diameter of the small intestine is about 25 to 4 mm, and the % of the large intestine, the diameter of the colon and the rectum is about 4 to 6 mm, and the intestinal tract has a contracting ability, the expandable capsule endoscope 2 The size is smaller than the smallest diameter of the small intestine before unexpanded, and smaller than the smallest diameter of the large intestine after expansion. The expansion function module 22 is disposed within the expandable structure 23 and includes a remote control receiving bypass 221. The remote control receiving circuit 221 can receive an expansion start signal issued by the external control device 3, and activate an expansion mechanism according to the expansion start signal to control the expansion of the expandable structure 23. In the present embodiment, the expansion mechanism controls the reaction material to produce a gas-filled structure 23. For example, the reactive material of the expansion function module 22 may be a solid gas storage material or a compressed gas, and is sealed and stored in a storage chamber. The lx·body δ is further provided with an active separation structure, and when the remote control receiving circuit 221 receives an expansion start signal, the movement of the movable separation structure can be controlled to open the cavity. Then, the reaction material releases a non-toxic gas into the expandable structure 23, thereby expanding the expandable structure 23. Preferably, in the embodiment, the expansion function module 22 includes a storage cavity 224, a first reaction substance 225 and a second reaction substance 226, and utilizes an electromagnetic valve formed by the electromagnetic coil 222 and the valve 223. As a separate structure for activities. The first reactive material 225 is disposed outside the storage cavity 224, and the second reactive material 226 is sealed and stored in the storage cavity 224. The electromagnetic valve seals the opening of the reservoir cavity 224 prior to initiating the expansion of the 201127336 expansion mechanism, thereby isolating the first reactant 225 from the second reactant 226. When the expansion function module 22 receives the expansion start signal from the external control device 3, the expansion function module 22 will energize the electromagnetic coil 222 to generate a magnetic field to move the valve 223, thereby causing the first reaction substance 225 to react with the second reaction. The space in which the substance 226 is located is connected. Thereby, the first reaction substance 225 can be contacted with the second reaction substance 226 to react to generate a gas, thereby filling the expandable structure 23. In practical applications, the first reactive material 225 may be a carbonate, a hydrogencarbonate or a mixture thereof, and the second reactive material 226 may be a pair of a slightly acidic, slightly acidic liquid. When the solenoid valve is opened, the second reactant 226 can flow out of the storage chamber 224 and contact the first reactant 225. The first reaction substance 225 can react with the second reaction substance 220 to gradually generate carbon dioxide, and expand the expandable structure 23 to a moderately large external control device 3 including the remote control transmitting unit 31, the wireless receiving unit 32, and the processing unit 33. The display module 34 and the data storage module 35. The remote transmitting unit 31 is configured to emit an expansion start signal. The wireless receiving unit % is used to receive the digital image poorness transmitted by the wireless transmitting circuit 213 from the endoscope function module 21. The processing unit 33 can store the received digital image information to the data storage module 35 for later viewing. In addition, the processing unit % can also display the received digital image information from the display module 34. Thereby, the examiner can instantly view the image of the digestive tract returned by the expandable capsule endoscope 2. When the inflatable capsule endoscope 2 intestine is found, Shihu material (4) fresh illusion 201127336 swelled capsule squint mirror 2 will start the expansion mechanism after the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ To a predetermined volume, in order to open the inner wall of the large intestine, the expandable capsule endoscope 2 can easily obtain a clear image of the intestinal wall, and avoid rolling to maintain the consistency of the kneading direction. In summary, the expandable capsule endoscope system 1 and the expandable capsule endoscope 2' of the present invention enable the endoscopic examination of the capsule to extend its application range to the large intestine. In view of the fact that the lesions of the large intestine are much more global than the cases of small intestine and large intestine lesions, the present invention can reduce the cost and risk of colorectal examination, reduce the pain caused by the pain of colonoscopy, and even greatly reduce the chance of colorectal cancer deterioration. The features and spirit of the present invention are intended to be more apparent from the detailed description of the preferred embodiments. On the contrary, the purpose is to accommodate various changes and equal arrangements within the scope of the present invention. To the extent that the scope of the patented scope of the invention is to be interpreted broadly in light of the above description, all possible changes and equivalent arrangements.
