Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to an anti-fouling auxiliary device for endoscopic examination. Background Technology

[0002] During electronic enteroscopy, an outer cannula is typically placed over the endoscope. This cannula is inserted into the patient's small intestine, and the endoscope moves within it. The endoscope, the outer cannula, and the balloon device on the outer cannula work together to assist in the observation, diagnosis, imaging, insertion, and treatment of the small intestine and the internal cavities of the digestive system, from the upper to the lower digestive tract.

[0003] Clinical experience has shown that, due to the need for gas injection during electronic enteroscopy, if bowel preparation is inadequate or the field of vision is unclear, the intestinal lumen needs to be repeatedly flushed with defoaming agents and sterile saline during the procedure. This results in a significant amount of fluid within the intestinal lumen, and there is a possibility that contaminated water from the intestinal lumen may flow out along the outer cannula during the procedure, leading to contamination of the operating table and operating room. Medical staff also need to wear multiple layers of protective clothing and boots, and the procedure time and anesthesia time are increased, causing operator fatigue. To address this issue, this disposable anti-contamination auxiliary device was developed after repeated experiments. Utility Model Content

[0004] The purpose of this invention is to provide an anti-fouling auxiliary device for endoscopic examination. This device achieves a seal by fitting and fixing it to the inlet of the outer tube, and by sealing it by fitting the valve component to the surface of the endoscope, thereby blocking sewage and reducing the risk of contamination of the operating table and operating room.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] An anti-fouling auxiliary device for endoscopic examination includes a main body, which is a hollow cylindrical structure with openings at both the top and bottom. The upper opening of the main body is adapted to and sealed to the surface of the endoscope. A spherical valve component is provided at the upper opening of the main body. The valve component includes several valves arranged at equal intervals around the circumference, with the edges of adjacent valves fitting together to form a closed opening. The lower opening of the main body is adapted to and sealed to the outer surface of the sheath catheter. An inwardly protruding annular buckle is provided inside the lower opening of the main body. The main body, the valve component, and the annular buckle are all elastic.

[0007] In the above technical solution, preferably, the main body includes a fixed section and a curved section. The fixed section and the curved section are hollow structures connected vertically. The internal cavities of the fixed section and the curved section are connected. The fixed section is adapted to be sealed and fitted to the outer surface of the inlet position of the outer sheath catheter, and the curved section is adapted to be sealed and fitted to the outer surface of the endoscope.

[0008] In the above technical solution, preferably, two annular buckles are provided, including an upper annular buckle near the middle position of the fixed section and a lower annular buckle near the lower opening of the fixed section.

[0009] In the above technical solution, preferably, the left and right ends of the upper annular buckle are fixed to the inner wall of the fixed section, and the remaining positions of the upper annular buckle are separated from the inner wall of the fixed section.

[0010] In the above technical solution, preferably, the main body, valve component, and annular buckle are integrally molded from silicone.

[0011] Compared with the prior art, this utility model has the following advantages and effects:

[0012] This invention achieves a seal by fitting the lower opening of the main body onto the inlet of the outer cannula, ensuring a tight fit with the surface of the outer cannula. A ring-shaped buckle is fitted and secured to the protruding ring at the inlet of the outer cannula. The endoscope is then inserted from the valve position, causing the valves to separate. The valve expands and, due to its elasticity, remains in contact with the surface of the endoscope, achieving a seal. This sealed fit between the main body, the outer cannula, and the endoscope effectively prevents wastewater from flowing out along the outer cannula, reducing the risk of contamination of the work surface and operating room. It also solves the problems of medical personnel needing to wear multiple layers of protective clothing and boots, increasing operation time, and prolonging anesthesia time.

[0018] The components include: main body 1, fixed section 11, curved section 12, valve component 2, valve 21, annular buckle 3, upper annular buckle 31, lower annular buckle 32, endoscope 4, outer cannula 5, and raised ring 51. Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0020] See Figures 1-5 This embodiment discloses an anti-fouling auxiliary device for endoscopic examination, comprising a main body 1. The main body 1 is a hollow cylindrical structure with openings at both the top and bottom. The upper opening of the main body 1 is adapted to and sealed to the surface of the endoscope 4. A spherical valve component 2 is provided at the upper opening of the main body 1. The valve component 2 includes several valves 21 arranged at equal intervals around the circumference. The edges of adjacent valves 21 are fitted together to form a closed opening. The lower opening of the main body 1 is adapted to and sealed to the outer surface of the outer cannula 5. An inwardly protruding annular buckle 3 is provided inside the lower opening of the main body 1. The main body 1, the valve component 2, and the annular buckle 3 are all elastic.

[0021] In use, this invention first expands the lower opening of the main body 1 so that it fits onto the inlet of the outer cannula 5. The annular buckle 3 matches the protruding ring 51 at the inlet of the outer cannula 5, securing and fixing the main body 1 and reducing the risk of it falling off the outer cannula 5 when pulled. The main body 1, under its own elasticity, fits tightly against the surface of the outer cannula 5 to achieve a seal. Then, the endoscope 4 is inserted from the valve 2 position, causing the valves 21 to separate. The valve 2 expands and, under its own elasticity, remains in contact with the surface of the endoscope 4 to achieve a seal. Therefore, when sewage from the patient's intestines flows outward along the outer cannula 5, the sealed fit between the main body 1, the outer cannula 5, and the endoscope 4 can block the sewage, reducing the risk of sewage flowing out along the outer cannula 5 and contaminating the operating table and operating room. At the same time, it can solve the problems of medical staff needing to wear multiple layers of protective clothing and boots, as well as increasing operation time and prolonging anesthesia time.

[0022] When the endoscope 4 is not inserted, the adjacent valves 21 can maintain an edge-to-edge fit, so the valve 2 forms a closed opening, which can also play a sealing role when the endoscope 4 is not inserted, reducing the risk of sewage leakage.

[0023] See Figure 1 , Figures 3-5 The main body 1 includes a fixed section 11 and a curved section 12. The fixed section and the curved section 12 are hollow structures connected vertically. The internal cavities of the fixed section 11 and the curved section 12 are connected. The fixed section 11 is adapted to be sealed and fitted to the outer surface of the inlet position of the outer sheath catheter 5, and the curved section 12 is adapted to be sealed and fitted to the outer surface of the endoscope 4.

[0024] The increased contact area between the curved section 12 and the surface of the endoscope 4 improves the sealing effect. During the insertion of the endoscope 4 into the outer cannula 5, the curved section 12 bends inwards into the outer cannula 5 (e.g., ...). Figure 4 As shown in the diagram, during the withdrawal of the endoscope 4 from the outer cannula 5, the curved section 12 bends outward from the outer cannula 5 (as shown in the diagram). Figure 5 As shown in the figure, the curved section 12 can always keep in contact with the surface of the endoscope 4 to play a sealing role. At the same time, during the insertion of the endoscope 4, the curved section 12 can be located between the endoscope 4 and the outer cannula 5 to play a buffer role, reducing the risk of damage to the surface of the endoscope 4 caused by direct contact friction between the endoscope 4 and the outer cannula 5.

[0025] See Figures 3-5 The ring buckle 3 is provided in two parts, including an upper ring buckle 31 located near the middle of the fixed section 11 and a lower ring buckle 32 located near the lower opening of the fixed section 11.

[0026] When the fixing section 11 is fitted onto the outer conduit 5, the upper annular buckle 31 matches the protruding ring 51 at the inlet of the outer conduit 5 to achieve a locking and fixing effect. The upper annular buckle 31 and the lower annular buckle 32 allow the fixing section 11 to fit against the outer surface of the outer conduit 5, increasing the contact area between the fixing section 11 and the outer conduit 5. When the main body 1 is subjected to a large external force that causes the upper annular buckle 31 to separate from the outer conduit 5 or even fall off the outer conduit 5, the lower annular buckle 32 can play a sealing and locking and fixing role, reducing the risk of the main body 1 falling directly off the outer conduit 5, thereby improving the leakage prevention effect of this utility model and improving the stability of this utility model in use.

[0027] See Figure 3 The left and right ends of the upper annular buckle 31 are fixed to the inner wall of the fixed section 11, and the remaining positions of the upper annular buckle 31 are separated from the inner wall of the fixed section 11.

[0028] During installation, the lower annular buckle 32 is first folded upwards from the outside to expose the upper annular buckle 31. Then, fingers or other tools (such as tweezers) are inserted into the gaps between the front and rear sides of the upper annular buckle 31 and the inner wall of the fixing section 11. The upper annular buckle 31 is pulled outwards to expand and fit under the protruding ring 51 of the outer guide tube 5 for locking and fixing. Finally, the lower annular buckle 32 is pushed downwards to move to the lower side of the upper annular buckle 31, ultimately allowing the fixing section 11 to unfold and return to its original position, thus completing the installation of this utility model. In this utility model, the separation of the upper annular buckle 31 from the inner wall of the fixing section 11 facilitates expansion of the upper annular buckle 31 by the operator, improving the ease of installation.

[0029] The main body 1, valve component 2, and annular buckle 3 are integrally molded from silicone.

[0030] Silicone has the advantage of being flexible, allowing the bending section 12 to repeatedly rotate and adhere to the surface of the endoscope 4 during repeated insertion and removal, thus reducing wear on the surface of the endoscope 4. In addition, silicone is a low-cost material. Therefore, when this invention is used as a disposable consumable, it can reduce surgical costs and will not increase the economic burden on patients.

[0031] In mass production, the main body 1, valve component 2, and annular buckle 3 are first integrally formed by mold. Then, a valve 21-shaped opening is formed by cutting at the closed end of the curved section 12. Finally, the fixed section 11 is flipped over to expose the upper annular buckle 31 on the outside. The upper annular buckle 31 is partially cut and separated from the inner wall of the fixed section 11. This production process is relatively simple and is conducive to the mass production of this utility model.

[0032] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
