Description

Technical Field

[0001] This utility model relates to the field of capsule endoscopy technology, and in particular to a painless gastroscopy for physical examination. Background Technology

[0002] Gastroscopy is one of the most commonly used methods for examining diseases in gastroenterology. Current gastroscopes mainly consist of a lens and a guide tube. During the examination, a thin, flexible tube is inserted into the stomach, allowing doctors to directly observe lesions in the esophagus, stomach, and duodenum, especially small ones. However, the procedure is quite painful because the endoscope needs to be slowly inserted into the mouth until it reaches the base of the tongue, which can cause significant nausea and is inconvenient to perform.

[0003] To change this situation, a capsule endoscope was designed, which installs communication equipment and image sensors in a corrosion-resistant capsule. When the patient swallows the capsule endoscope, it begins to take pictures of the stomach at preset time intervals and transmits the pictures to a computer.

[0004] Prior art CN218738879U discloses an angle-controllable capsule endoscope and a capsule endoscope control system. The angle-controllable capsule endoscope includes a counterweight adjustment device, which includes a mounting shell. A screw is rotatably inserted through one side of the mounting shell, and a counterweight valve is threaded onto the screw. The counterweight valve is located inside the mounting shell, and a first motor is connected to one end of the screw.

[0005] However, during the continuous imaging process inside the human body, the capsule endoscope may accumulate debris in the viewing window, affecting the imaging.

[0006] Therefore, there is an urgent need to provide a painless gastroscopy for physical examinations that ensures clear imaging compared to existing technologies. Utility Model Content

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] like Figure 1As shown, this utility model provides a painless gastroscopy for physical examination, including a main body 1, a front shell 2, a rear shell 3, a cleaning assembly 4, a lens 8, a processor 5, a radio frequency antenna 6, and a battery 7. The main body 1 is a hollow structure with openings at both ends. The front shell 2 and the rear shell 3 are both hemispherical structures and are made of transparent material. One end of the main body 1 is connected to the front shell 2, and the other end is connected to the rear shell 3. A cleaning assembly 4 is installed inside the connection between the front shell 2 and the main body, and another cleaning assembly 4 is installed inside the connection between the rear shell 3 and the main body. Each cleaning assembly 4 is connected to a lens 8. That is, the main body 1 is divided into two parts. Each lens 8 is equipped with a processor 5, an RF antenna 6, and a battery 7, which are fixedly connected inside the main body 1. Each lens 8 is electrically connected to a processor 5, and the processor 5 is connected to the RF antenna 6. The battery 7 is fixedly connected inside the main body 1. The battery 7 is used to power the internal system of the endoscope. The endoscope is also electrically connected to an external receiver. After the lens 8 captures an image, it is stored in the processor 5. The image data is transmitted to the external receiver through the wireless RF circuit of the RF antenna 6. The external receiver is connected to a computer or other display device, which can transmit the image to the computer or other display device.

[0033] The circuit connecting the lens 8 to the processor 5, the wireless radio frequency circuit of the radio frequency antenna 6, the connection circuit between the receiver and the computer or other display device, and the circuit powered by the battery 7 all use existing publicly available circuits, which will not be described in detail here.

[0034] like Figure 2 , Figure 3 , Figure 6 As shown, the cleaning component 4 includes a rotating shell 41, a drive assembly, a first rotating shaft 42, and a second rotating shaft 49. The first rotating shaft 42 is inserted at the connection between the front shell 2 and the main body 1, and at the connection between the rear shell 3 and the main body 1. The second rotating shaft 49 is externally rotatably connected to the first rotating shaft 42. The first rotating shaft 42 and the second rotating shaft 49 move in opposite directions via the drive assembly. Both ends of the first rotating shaft 42 extend out of the main body 1, and the rotating shell 41 is fitted onto both ends of the first rotating shaft 42 extending out of the main body 1. The rotating shell 41 rotates synchronously with the first rotating shaft 42. The rotating shell 41 has a quarter-sphere structure and provides shielding. The front shell 2 or rear shell 3 is partially structured; the rotating shell 41 is fitted against the outer wall of the front shell 2 or the outer wall of the rear shell 3; a lens 8 is mounted on the second rotating shaft, and the lens 8 rotates synchronously with the second rotating shaft 49. The lens 8 is always facing the part of the front shell 2 or the rear shell 3 that does not obstruct the rotating shell 41, which facilitates the shooting of the lens 8; at the same time, the rotating shell 41 is fitted against the front shell 2 or the rear shell 3, and during the rotation of the rotating shell 41, the debris stuck to the front shell 2 and the rear shell 3 can be cleaned. The lens 8 is always aimed at the cleaned position of the protective shell, so that the image taken by the lens 8 has high clarity.

[0035] The main body 1 has two fixed plates 9 fixedly connected inside, with the two fixed plates 9 spaced apart. Two cleaning components 4 are located on the outside of the two fixed plates 9. A processor 5 is connected to the inside of each fixed plate 9. The radio frequency antenna 6 and the battery 7 are located between the two fixed plates 9. The first rotating shaft 42 is fitted with brackets 44 at both ends. The first rotating shaft 42 is rotatably connected to the brackets 44. The brackets 44 are vertically fixed on the side wall of their corresponding fixed plates 9.

[0036] The drive assembly includes a first bevel gear 46, a second bevel gear 47, a third bevel gear 48, and a motor 410. A support plate 45 is vertically fixed to the outer sidewall of the fixing plate 9, and a motor 410 is fixedly connected to the lower wall of the support plate 45. The output end of the motor 410 passes through the support plate 45 and connects to the second bevel gear 47. The second bevel gear 47 is rotatably connected to the support plate 45, and the first bevel gear 46 and the third bevel gear 48 mesh on the second bevel gear 47. The first bevel gear 46 is sleeved outside the first rotating shaft 42 and rotates synchronously with the first rotating shaft 42. The third bevel gear 48 is sleeved outside the second rotating shaft 49 and rotates synchronously with the second rotating shaft 49. The motor 410 is selected as a servo motor 410. The motor 410 drives the second bevel gear 47 to rotate, which in turn drives the first bevel gear 46 and the third bevel gear 48 to rotate in opposite directions, thereby causing the first rotating shaft 42 and the second rotating shaft 49 to rotate in opposite directions. This allows the rotating shell 41 to wipe the front shell 2 or the rear shell 3 while ensuring that the lens 8 can take pictures normally.

[0037] like Figure 4 , Figure 5 As shown, multiple grooves 11 are spaced apart on both ends of the main body 1, and a first magnet 12 is fixedly connected to the bottom of each groove 11; multiple first protrusions 21 are provided on the end face of the front shell 2, and a second magnet 22 is fixedly connected to the outer end face of each first protrusion 21. The second magnet 22 has opposite magnetic properties to the first magnet 12. The multiple first protrusions 21 provided on the front shell 2 are arranged one-to-one with the multiple grooves 11 provided on one side of the main body 1. When the multiple first protrusions 21 are inserted into their corresponding grooves 11, the second magnet 22 and the corresponding first protrusion 12 are connected to the grooves 11. A magnet 12 attracts the front shell 2 and the body 1, making them firmly connected. The end face of the rear shell 3 is provided with a plurality of second protrusions 31, and a third magnet 32 ​​is fixedly connected to the outer end face of each second protrusion 31. The magnetism of the third magnet 32 ​​is opposite to that of the first magnet 12. The plurality of second protrusions 31 provided on the rear shell 3 are provided in a one-to-one correspondence with the plurality of grooves 11 provided on the other side end face of the body 1. When the plurality of second protrusions 31 are inserted into their corresponding grooves 11, the third magnet 32 ​​attracts the corresponding first magnet 12, making the rear shell 3 and the body 1 firmly connected.

[0038] like Figure 2 , Figure 7 , Figure 8As shown, the front shell 2 is provided with a first circular groove 23, and the rear shell 3 is also provided with a second circular groove 33. The body 1 is also provided with circular grooves corresponding to the positions of the first circular groove 23 and the second circular groove 33. After the front shell 2 and the rear shell 3 are connected to the body 1, the first rotating shaft 42 passes through the first circular groove 23 and the second circular groove 33 respectively and exits the body 1. The rotating shell 41 is connected to the first rotating shaft 42 through the connecting cover 43 to achieve synchronous rotation. The two ends of the rotating shell 41 are integrally connected to the rotating ring 411. The rotating ring 411 is provided with a plurality of first rectangular grooves 412 along its circumference. The end of the first rotating shaft 42 is provided with a second rectangular groove 421. The inner sidewall of the connecting cover 43 is provided with a first rectangular block 431 and a plurality of second rectangular blocks 432. The first rectangular block 431 is positioned at the center of the connecting cover 43, and multiple second rectangular blocks 432 are spaced around the first rectangular block 431. The size of the first rectangular block 431 corresponds to the size of the second rectangular groove 421, and the size of the second rectangular block 432 corresponds to the size of the first rectangular groove 412. After both ends of the first rotating shaft 42 extend out of the first circular groove 23 or the second circular groove 33, the two rotating rings 411 of the rotating shell 41 are fitted onto both ends of the first rotating shaft 42, and then the connecting cover 43 is placed on each end, so that the first rectangular block 431 extends into the second rectangular groove 421 and the second rectangular block 432 extends into the first rectangular groove 412, thus completing the fixed connection of the connecting cover 43, the first rotating shaft 42, and the rotating shell 41.

[0039] This invention, by setting a driving component, rotatably connects a rotating shell 41 to the outside of both the front shell 2 and the rear shell 3, causing the rotating shell 41 to rotate in the opposite direction to the lens 8. This ensures that the lens 8 is always aligned with the part of the front shell 2 or the rear shell 3 that is not covered by the rotating shell 41. At the same time, the lens 8 is always aligned with the position after the rotating shell 41 has been wiped clean, which can improve the clarity of the image captured by the lens 8.

[0040] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
