Description

Technical Field

[0001] This utility model relates to the field of cholangioscopic technology, specifically to a disposable cholangioscopic endoscope. Background Technology

[0002] Traditional reusable cholangioscopes require repeated cleaning and disinfection. If the process is not standardized, pathogens such as hepatitis B, hepatitis C, and HIV may remain. Disposable cholangioscopes, through their use and disposal model, completely block cross-infection routes and are especially suitable for patients with weakened immune systems. Moreover, they do not require dedicated cleaning and disinfection equipment. Therefore, disposable cholangioscopes play an irreplaceable role in clinical diagnosis and treatment.

[0003] However, disposable cholangioscopy tubes must be disposed of strictly in accordance with medical waste classification standards after the diagnostic and treatment procedures are completed. Given the relatively long length of the cholangioscopy tube and the fact that its outer wall is highly susceptible to contamination with pathogens such as hepatitis B, hepatitis C, and HIV, medical personnel inevitably come into contact with the tube during the process of returning the cholangioscopy tube to the designated plastic bag. This significantly increases the risk of occupational exposure for medical personnel, thus making the cholangioscopy tube recycling process quite inconvenient.

[0004] Therefore, a disposable cholangioscope was proposed to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a disposable cholangioscope to address the issue raised in the background section where disposable cholangioscopes require strict disposal according to medical waste classification standards after diagnostic and treatment procedures. Given the relatively long length of the cholangioscope cannula and its easily contaminated outer wall with pathogens such as hepatitis B, hepatitis C, and HIV, medical personnel inevitably come into contact with the cannula during the process of returning the cholangioscope to a dedicated plastic bag. This significantly increases the risk of occupational exposure for medical personnel, leading to numerous inconveniences in the cholangioscope recycling process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a disposable cholangioscope, including a cholangioscope handle;

[0007] One end of the cholangioscope handle is fixedly connected to a cannula;

[0008] Also includes:

[0009] A flip frame is fixedly connected to one side of the lower end of the cholangioscope handle. A rotating seat is rotatably connected to one side of the flip frame. A connecting shaft is fixedly connected to the middle of the lower end of the rotating seat. A torsion spring is sleeved in the middle of the connecting shaft. A rotating frame is rotatably connected to one side of the connecting shaft. A clamping plate is fixedly connected to the bottom of the rotating frame.

[0010] The clamping plate has a pressing handle fixedly connected to one side of its top end. A contraction groove is formed in the middle of the clamping plate. A limit rod is fixedly connected to one side of the inner wall of the contraction groove. A limit spring is sleeved on the outer side of the limit rod. A limit block is fixedly connected to one side of the limit spring. A limit groove is formed on one side of the limit block. An opening is provided on the other side of the limit block.

[0011] Preferably, the rotating seat is configured as an inverted U-shape, and the connecting shaft is fixedly connected to the middle of the lower end of the rotating seat to facilitate the positioning of the rotating seat.

[0012] Preferably, the rotating frame is symmetrically arranged on both sides of the connecting shaft, and the two ends of the torsion spring are respectively connected to the bottom surface of the lower end of the rotating seat and the top surface of the clamping plate, which facilitates the positioning of the torsion spring.

[0013] Preferably, the rotating seat, clamping plate, and pressing handle are symmetrically arranged on both sides of the flipping frame to facilitate the limiting of the clamping plate.

[0014] Preferably, at least two sets of the limiting rod, limiting spring, limiting block, and limiting groove are provided, and the limiting rod, limiting spring, limiting block, and limiting groove are evenly arranged on one side of the shrinkage groove to facilitate the positioning of the limiting block.

[0015] Preferably, the limiting rod is slidably connected to the limiting block via a limiting groove, and the limiting block is slidably connected to the side of the clamping plate near the flipping frame, which facilitates the limiting of the limiting rod.

[0016] Preferably, the opening is located in the middle of the bottom of the two sets of clamping plates, and the limiting blocks on one side of the two sets of clamping plates overlap to facilitate the positioning of the limiting blocks at the clamping plates.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This disposable cholangioscope, by pressing the handle, unfolds the clamping plate, which facilitates sequential positioning of the cannula bend, thereby reducing the contact between medical personnel and the cannula, thus improving the safety of the disposable cholangioscope. Furthermore, the flipping of the clamping frame prevents it from interfering with the use of the cholangioscope. The specific details are as follows:

[0018] 1. This disposable cholangioscope, by incorporating a connecting shaft, torsion spring, clamping plate, pressing handle, retraction groove, limiting rod, limiting spring, limiting block, and limiting groove, facilitates the unfolding of the clamping plate by pressing the pressing handle. This allows for easy positioning of the bent insertion tube. Furthermore, by reducing the pressing force, the limiting blocks retract sequentially, achieving a sequential positioning effect at the bend of the insertion tube and preventing the insertion rod from loosening. This reduces the likelihood of medical personnel coming into contact with the insertion rod, thereby improving the safety of the disposable cholangioscope and enhancing its practicality.

[0019] 2. This disposable cholangioscope, with its flip-over frame and rotating base, facilitates the flipping of the clamp during cannulation, thus preventing the clamp from interfering with the use of the cholangioscope and making it more practical. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5This utility model provides a technical solution: a disposable cholangioscope, including a cholangioscope handle 1; one end of the cholangioscope handle 1 is fixedly connected to an insertion tube 2; it also includes: a flip frame 3 fixedly connected to one side of the lower end of the cholangioscope handle 1, a rotating seat 4 rotatably connected to one side of the flip frame 3, a connecting shaft 5 fixedly connected to the middle of the lower end of the rotating seat 4, a torsion spring 6 sleeved in the middle of the connecting shaft 5, a rotating frame 7 rotatably connected to one side of the connecting shaft 5, and a clamping plate 8 fixedly connected to the bottom of the rotating frame 7; the rotating seat 4 is provided with The rotating frame is U-shaped, with the connecting shaft 5 fixedly connected to the middle of the lower end of the rotating seat 4. The rotating frame 7 is symmetrically arranged on both sides of the connecting shaft 5, and the two ends of the torsion spring 6 are respectively connected to the bottom surface of the lower end of the rotating seat 4 and the top surface of the clamping plate 8. The rotating seat 4, the clamping plate 8 and the pressing handle 9 are symmetrically arranged on both sides of the flipping frame 3. By setting the rotating seat 4, it is easy to flip the position of the clamping plate 8, reduce the impact of the clamping plate 8 on the use of the insertion tube 2, and by setting the torsion spring 6, it is easy to clamp and reset the clamping plate 8.

[0028] The clamping plate 8 has a pressing handle 9 fixedly connected to one side of its top end. A contraction groove 10 is formed in the middle of the clamping plate 8. A limit rod 11 is fixedly connected to one side of the inner wall of the contraction groove 10. A limit spring 12 is sleeved on the outer side of the limit rod 11. A limit block 13 is fixedly connected to one side of the limit spring 12. A limit groove 14 is formed on one side of the limit block 13, and an opening 15 is provided on the other side of the limit block 13. At least two sets of limit rods 11, limit springs 12, limit blocks 13, and limit grooves 14 are provided, and these components are evenly distributed on one side of the contraction groove 10. The rod 11 is slidably connected to the limiting block 13 via the limiting groove 14. The limiting block 13 is slidably connected to the side of the clamping plate 8 near the flipping frame 3. The opening 15 is located in the middle of the bottom of the two sets of clamping plates 8. The limiting blocks 13 on one side of the two sets of clamping plates 8 overlap. By setting the limiting spring 12 and the limiting block 13, it is easy to realize the sequential expansion and contraction of the limiting block 13 according to the clamping angle of the clamping plate 8. This makes it easy for the insertion tube 2 to be clamped between the limiting blocks 13 in a wave-like manner, thereby preventing the insertion rod from becoming loose. This reduces the contact between medical personnel and the insertion rod, thus improving the safety of disposable cholangioscopes.

[0029] Working principle: After using the disposable cholangioscope, firstly, by rotating the clamping plate 8, the rotating seat 4 on one side of the clamping plate 8 rotates on the flipping frame 3, so that the clamping plate 8 falls on one side of the insertion tube 2.

[0030] Next, by pressing the pressing handle 9, the pressing handle 9 drives the clamping plate 8 to rotate on one side of the connecting shaft 5 via the rotating frame 7. At this time, the torsion spring 6 contracts. Subsequently, the limiting spring 12 in the contraction groove 10 pushes the limiting block 13, causing the limiting block 13 to slide on the limiting rod 11 through the limiting groove 14, so that the limiting block 13 unfolds. Then, the insertion tube 2 is clamped in the limiting block 13 bracket through the opening 15.

[0031] Finally, slowly lower the pressing handle 9 so that the limiting blocks 13 clamp in sequence, and then bend the insertion tube 2 in sequence and clamp it between the limiting blocks 13. Then, the cholangioscope can be discarded by holding the cholangioscope handle 1.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
