A secondary conduit 2 is disposed on one side of the main tube 4. The secondary conduit 2 is detachably connected to the main tube 4 through a connecting mechanism. A hollow gooseneck tube 3 is disposed on one side of the secondary conduit 2. The angle of the hollow balloon 11 can be adjusted by the setting of the hollow gooseneck tube 3, and water can be transported at the same time. A balloon structure 1 is disposed on one side of the secondary conduit 2.

[0031] The capsule structure 1 includes a hollow capsule 11. The bottom surface of the hollow capsule 11 is disposed on the outer surface of the auxiliary conduit 2. Multiple sets of water inlet pipes 12 are also disposed on one side of the auxiliary conduit 2. The water inlet pipes 12 are connected to the hollow capsule 11. An adjusting ring 13 is also disposed on one side of the hollow capsule 11. The adjusting ring 13 is slidably disposed on the auxiliary conduit 2. The adjusting ring 13 is disposed at the bottom of the hollow capsule 11 and is sealed to the hollow capsule 11 to ensure the airtightness of the hollow capsule 11.

[0032] When a digestive tract examination is required, this device is delivered into the patient's digestive tract through the patient's mouth or nose. The hollow capsule 11 is moved to the lower side of the examination target. During the insertion process, the angle of the hollow capsule 11 can be adjusted according to the bends of the digestive tract through the hollow gooseneck tube 3 to ensure a tight fit with the digestive tract. Water is then delivered into the hollow capsule 11 through the main tube 4 and the auxiliary tube 2. When the hollow capsule 11 expands, it can drive the adjusting ring 13 to move on the auxiliary tube 2, which can make the hollow capsule 11 expand rapidly and block the digestive tract. Then, airless water is injected into the digestive tract, and the examination is performed in conjunction with the endoscopic ultrasound probe.

[0033] Furthermore, a guide block 14 is provided on the inner wall of the adjusting ring 13. The guide block 14 is slidably disposed in the guide groove 15, which is disposed on the outer surface of the auxiliary guide tube 2. When the adjusting ring 13 moves, the adjusting ring 13 drives the guide block 14 to move within the guide groove 15, thereby improving the stability of the adjusting ring 13 during movement.

[0034] Furthermore, a first spring 16 is provided on one side of the guide groove 15. One end of the first spring 16 is connected to the guide block 14. During the introduction process, the elastic force of the first spring 16 can stretch the hollow bladder 11 and ensure its flatness. During the export process, the elastic force of the first spring 16 can automatically reset the hollow bladder 11, which facilitates the export of this device.

[0035] As a specific embodiment of this application, please refer to Figures 5-7The connecting mechanism comprises a connecting sleeve 21 arranged on one side of the secondary conduit 2, an annular groove 22 arranged on the connecting sleeve 21, and an installation groove 23 arranged on one side of the primary conduit 4, wherein one end of the connecting sleeve 21 is clamped in the installation groove 23, and a plurality of sets of positioning assemblies are arranged in the installation groove 23 and clamped with the annular groove 22, so that the primary conduit 4 and the secondary conduit 2 can be quickly connected.

[0036] In use, first, the connecting sleeve 21 on the secondary conduit 2 is inserted into the installation groove 23, and in the process of inserting the connecting sleeve 21, the positioning buckle 26 is driven to move in the groove body 24, the positioning buckle 26 is compressed when moving the second spring 25, and when the connecting sleeve 21 is completely clamped into the installation groove 23, the second spring 25 clamps the positioning buckle 26 into the annular groove 22 under the action of the elastic force, fixes the connecting sleeve 21, and quickly installs the secondary conduit 2 and the primary conduit 4.

[0037] Further, the positioning buckle 26 is a hemispherical structure, and the positioning buckle 26 is clamped in the annular groove 22, so that the positioning buckle 26 can be automatically guided into the annular groove 22.

[0038] Further, a magnet block 27 is arranged on one side surface of the installation groove 23, and the magnet block 27 is used for adsorbing and connecting the connecting sleeve 21, so that after the connecting sleeve 21 is clamped into the installation groove 23, the magnet block 27 adsorbs and fixes the connecting sleeve 21, and the firmness of the connection between the primary conduit 4 and the secondary conduit 2 is improved.

[0039] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
