[0003] A gastroscopy is performed by inserting a thin, flexible endoscope tube into the stomach. This tube includes a biopsy channel, air / water delivery nozzles, a lens, and a lighting fixture. The biopsy channel is used to insert instruments, the air / water delivery nozzles are used to deliver air and water, the lens is used to image the inside of the stomach, and the lighting fixture provides illumination. Current gastroscopes only allow the removal of gastric fluid and cannot remove foreign objects, which can clog the endoscope tube. Therefore, fasting is required before a gastroscopy. Summary of the Invention

[0004] The present invention provides a gastroscope that facilitates the removal of stomach contents, having a secondary connecting tube. Stomach contents entering the secondary connecting tube can be broken down by a contents fragmentation component, thereby facilitating the discharge of the contents through the secondary connecting tube.

[0005] This invention provides a gastroscope for easy removal of stomach contents, comprising a main gastroscope tube and a secondary connecting tube. During use, the secondary connecting tube is arranged side-by-side with the main gastroscope tube. The secondary connecting tube includes an insertion end for inserting into the stomach and a connection end for connecting to a negative pressure device. A debris-disintegrating component is fixed within the secondary connecting tube near the insertion end. The debris-disintegrating component includes a blade portion, comprising a first blade and a second blade. The included angle between the first surface of the first blade and the second blade facing the opening at the insertion end is not equal to 180°, and the first surface has a cutting edge.

[0006] Furthermore, the included angle of the first face is less than 180°, and the debris fragmentation component includes a needle that extends along the length of the secondary connecting tube and the tip of the needle faces the opening of the insertion end. An elastic element is connected between the needle and the blade portion.

[0007] Furthermore, the blade section also includes a third blade and a fourth blade. The secondary connecting pipe is provided with two opposing secondary holes at the corresponding positions of the debris fragmentation component. The first blade and the third blade correspond to one of the secondary holes, and the included angle between the second faces of the first blade and the third blade facing the secondary hole is less than 180°. The second blade and the fourth blade correspond to the other secondary hole, and the included angle between the second faces of the second blade and the fourth blade facing the secondary hole is less than 180°. The second face has a cutting edge.

[0008] Furthermore, the diameter of the needle is D1, the diameter of the secondary connecting tube is D2, and the ratio of D1 to D2 is 1:10 to 1:20.

[0009] Furthermore, the included angle between the first face of the first blade and the second blade facing the opening of the protruding end is greater than 180°.

[0010] Furthermore, the blade section also includes a third blade and a fourth blade. The secondary connecting pipe is provided with two opposing secondary holes at the corresponding positions of the debris fragmentation component. The first blade and the third blade correspond to one of the secondary holes, and the included angle between the second faces of the first blade and the third blade facing the secondary hole is greater than 180°. The second blade and the fourth blade correspond to the other secondary hole, and the included angle between the second faces of the second blade and the fourth blade facing the secondary hole is greater than 180°. The second face has a cutting edge.

[0011] Furthermore, the thickness of the blade portion is D3, the diameter of the secondary connecting pipe is D2, and the ratio of D3 to D2 is 1:20-1:50.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The gastroscope of the present invention includes a secondary connecting tube. During gastroscopy, the secondary connecting tube and the main gastroscope tube are inserted into the human stomach together. The connecting end of the secondary connecting tube is connected to a negative pressure device. The lens of the main gastroscope tube can provide an image inside the stomach, and the illumination lamp provides light, so that the position of the debris in the stomach can be seen, making it easier for the opening of the insertion end of the secondary connecting tube to be aligned with the debris. Under the action of negative pressure, the debris enters into the secondary connecting tube. When the volume of the debris is large, under the action of negative pressure, the debris can be split by the blades of the first and second blades, thereby reducing its volume and making it easier for it to pass through the secondary connecting tube.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component present. When a component is considered to be "placed on" another component, it can be directly placed on the other component or there may be an intervening component present. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0020] Please see Figure 1 This invention provides a gastroscopy for easy removal of stomach contents, comprising a main endoscope 10 and a secondary connecting tube 20. The main endoscope 10 includes a biopsy channel 11, an air / water delivery nozzle 12, a lens 13, and an illumination lamp 14. Instruments can be inserted through the biopsy channel 11, the lens 13 provides the doctor with images of the stomach, and the illumination lamp 14 provides light to illuminate the stomach. The air / water delivery nozzle 12 only allows gas or liquid to pass through, preventing the passage of debris (such as food particles). Therefore, the main endoscope 10 cannot expel stomach contents. The secondary connecting tube 20 is arranged side-by-side with the main endoscope 10 and can be secured by straps or other fixing structures, making the main endoscope 10 and the secondary connecting tube 20 an integral unit, thus facilitating entry into the stomach through the esophagus.

[0021] The secondary connecting tube 20 includes an insertion end A and a connecting end B. The insertion end A is used to extend into the stomach, and the connecting end B is used to connect to a negative pressure device that generates negative pressure. The negative pressure device can be a built-in negative pressure device of the endoscope or an additional negative pressure device (such as a negative pressure pump). Preferably, the inner diameter of the secondary connecting tube 20 is 4mm-8mm. This range of diameter facilitates not only the insertion of the endoscope into the body but also the removal of debris.

[0022] like Figure 2-4As shown, a debris fragmentation component 30 is fixed inside the secondary connecting pipe 20 near the insertion end A. The debris fragmentation component 30 includes a blade portion 31, which includes a first blade 311 and a second blade 312. The included angle P between the first surface of the first blade 311 and the second blade 312 facing the opening of the insertion end A is not equal to 180°. The first surface has a cutting edge 301.

[0023] When the endoscope of the present invention is inserted into the human stomach, the doctor can view the condition of the stomach through the lens 13, such as whether there are foreign objects or lesions. If there are foreign objects, the insertion end A can be aligned with the foreign objects. Under negative pressure, the foreign objects can enter the position of the foreign object fragmentation part 30 in the secondary connecting tube 20. Since the first blade 311 and the second blade 312 have a blade 301 on their first surfaces, the foreign objects have been initially softened by the gastric juice in the human stomach and the foreign object structure is irregular. The first surface is at an angle P, which can improve the contact position between the blade 301 and the foreign object and improve the effect of the blade part 31 in fragmenting the foreign objects, making it more convenient for the foreign objects to pass through the secondary connecting tube 20.

[0024] In the first embodiment, such as Figure 2 and Figure 3 As shown, the included angle P of the first surface is less than 180°, and the debris fragmentation component 30 includes a needle 32, which extends along the length of the secondary connecting pipe 20 and the tip of the needle 32 faces the opening of the insertion end A. An elastic element 33 is connected between the needle 32 and the blade portion 31. The elastic element 33 can be a spring or an elastomer made of rubber.

[0025] When debris passes through the secondary connecting pipe 20, some large-diameter debris will be punctured by the needle 32, and the needle 32 will compress the elastic element 33. When the large-diameter debris is punctured, the needle 32 will reduce the pressure on the elastic element 33, and the elastic element 33 will rebound. During the rebound of the elastic element 33, the needle 32 has a certain puncturing force, which can improve its puncturing force on the next debris passing through the same spot, thereby improving the fragmentation effect of the debris and further facilitating the passage of debris through the secondary connecting pipe 20.

[0026] The diameter of the needle 32 is D1, the diameter of the secondary connecting tube 20 is D2, and the thickness of the blade part 31 is D3. Preferably, the ratio of D1 to D2 is 1:10-1:20, and the ratio of D3 to D2 is 1:20-1:50. Using the needle 32 and blade part 31 within this size range, and with the thickness within a reasonable range, not only is it beneficial for the needle 32 and blade part 31 to break down the debris, but it will also not affect the passage of the debris.

[0027] In the second embodiment, such as Figure 4 As shown, the debris crushing component can be fixed inside the secondary connecting pipe 20 by a fixing component. The included angle P of the first surface is greater than 180°, so that the connection between the first blade 311 and the second blade 312 forms a tip 302 facing the inlet of the insertion end A. The tip 302 is also conducive to crushing the debris.

[0028] Furthermore, in the first and second embodiments, the blade portion 31 further includes a third blade 313 and a fourth blade 314. The secondary connecting pipe 20 is provided with two opposing secondary holes 21 at corresponding positions of the debris fragmentation component 30. The first blade 311 and the third blade 313 correspond to one of the secondary holes 21, and the second blade 312 and the fourth blade 314 correspond to the other secondary hole 21.

[0029] In the first embodiment, such as Figure 2 and Figure 3 As shown, the included angle Q1 between the first blade 311 and the third blade 313 facing the second surface of the secondary hole 21 is less than 180°, and the included angle Q2 between the second blade 312 and the fourth blade 314 facing the second surface of the secondary hole 21 is less than 180°. Thus, the blade portion 31 is approximately X-shaped, and the second surface has a cutting edge 303. Similarly, debris can enter the secondary connecting pipe 20 through the secondary hole 21. However, since the secondary hole 21 is located on the side wall of the secondary connecting pipe 20, the volume of debris entering is relatively small compared to the opening of the insertion end A. If debris enters the secondary connecting pipe 20 through the secondary hole 21, it can be well crushed by the angled cutting edge.

[0030] In the second embodiment, such as Figure 4 As shown, the included angle Q1 between the first blade 311 and the third blade 313 facing the second surface of the secondary hole 21 is greater than 180°, and the included angle Q2 between the second blade 312 and the fourth blade 314 facing the second surface of the secondary hole 21 is greater than 180°. Thus, the blade portion 31 is roughly prismatic, and the second surface has a cutting edge 303. Similarly, debris can enter the secondary connecting pipe 20 through the secondary hole 21. The connection point of the first blade 311 and the third blade 313 forms a tip 304 facing one of the secondary holes 21, and the connection point of the second blade 312 and the fourth blade 314 also forms a tip 305 facing the other secondary hole 21. Tips 304 and 305 are also conducive to piercing the debris.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
