Description

Technical Field

[0001] This utility model relates to a quick cleaning and switching device for endoscopes, belonging to the field of medical device technology. Background Technology

[0002] An endoscope is a precision medical device that integrates optics, mechanics, and electronics. It enters the human body through natural cavities or tiny incisions to achieve direct diagnosis and minimally invasive treatment of diseases.

[0003] The use of endoscopes is highly dependent on their sophisticated tubing systems, and thorough cleaning of these systems is a critical step in ensuring medical safety. Currently, the standard cleaning process typically involves manual pre-washing followed by mechanical final washing. However, in practice, the frequent disassembly and assembly processes can cause continuous mechanical wear on precision components such as seals and clips at the endoscope connection points. This cumulative damage can not only lead to operational risks such as leakage of irrigation fluid, but also significantly shorten the lifespan of the entire endoscope device and increase the equipment maintenance costs for medical institutions.

[0004] Therefore, it is urgent to improve the quick-release structure of endoscopes to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a quick cleaning and switching device for endoscopes. The limiting point is only the limiting block and the limiting groove on the inner wall of the connecting tube. This not only allows for quick disassembly of the first and second connecting tubes, but also reduces the wear of the sliding lock mechanism.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: an endoscope quick cleaning and switching device, comprising a first connecting tube and a second connecting tube, wherein a sliding lock mechanism is provided between the first connecting tube and the second connecting tube;

[0007] The sliding lock mechanism includes a first sliding cylinder fixedly connected to one end of the second connecting tube, a sliding limiting shell slidably disposed on the outside of the first sliding cylinder, and a second sliding cylinder slidably disposed on the inside of the first sliding cylinder. A connecting cylinder is slidably connected to one end of the second sliding cylinder, and the connecting cylinder is fixedly connected to one end of the first connecting tube.

[0008] The second sliding cylinder has limiting blocks on both sides that slide and engage with the inner side of the connecting cylinder.

[0009] Preferably, the first sliding cylinder, the sliding limiting shell, and the second sliding cylinder are respectively provided with a guide groove, a second inclined groove, and a first inclined groove, wherein the guide groove and the second inclined groove both extend to the inner side of the sliding limiting shell and the first sliding cylinder.

[0010] Preferably, a drive rod is slidably connected to the inner side of the first inclined groove. The drive rod is also slidably connected to the first sliding cylinder and the sliding limiting shell. A limiting plate is fixedly provided at one end of the drive rod, and one side of the limiting plate is in contact with the outer side of the sliding limiting shell.

[0011] Preferably, the first and second inclined grooves have opposite inclination angles, and the guide groove is used for sliding guidance of the drive rod.

[0012] Preferably, the inner wall of the connecting cylinder has limit slots on both opposite sides, and the limit slots are used to limit the sliding of the limit block.

[0013] Preferably, the inner wall of the connecting cylinder is provided with sliding guide grooves on opposite sides, and the two sliding guide grooves are located directly below the two limiting slots. The sliding guide grooves are used to guide the limiting block to slide.

[0014] Preferably, the second sliding cylinder has telescopic grooves on both sides for sliding and retracting the limiting block. One end of the limiting block is fixedly provided with a spring, and the other end of the spring is fixedly connected to the inside of the telescopic groove.

[0015] This utility model has at least the following beneficial effects:

[0016] When the staff needs to separate the first connecting pipe from the second connecting pipe, the first and second inclined grooves have opposite inclination angles. The guide groove is used to guide the sliding of the drive rod. First, the sliding limit shell and the first sliding cylinder are held. Then, the sliding limit shell is rotated, which allows the drive rod to slide in the guide groove. At this time, when the drive rod slides, it can use the sliding connection with the first and second inclined grooves to make the second sliding cylinder slide with the first sliding cylinder, thereby enabling the second sliding cylinder and the first sliding cylinder to extend and retract.

[0017] The setting of the limiting block allows the second sliding cylinder to slide into the connecting cylinder and engage with the inner side of the connecting cylinder, thereby fixing and limiting the connection between the second sliding cylinder and the connecting cylinder. The limiting point is only in the limiting slot of the limiting block and the inner wall of the connecting cylinder. This not only allows the first connecting pipe and the second connecting pipe to be quickly disassembled, but also reduces the wear of the sliding lock mechanism. Attached Figure Description

[0026] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] Examples, such as Figures 1-6 As shown, an endoscope quick cleaning and switching device includes a first connecting tube 1 and a second connecting tube 2. A sliding locking mechanism is provided between the first connecting tube 1 and the second connecting tube 2, which can quickly connect the first connecting tube 1 and the second connecting tube 2.

[0028] The sliding lock mechanism includes a first sliding cylinder 3 fixedly connected to one end of the second connecting pipe 2, a sliding limiting shell 4 slidably disposed outside the first sliding cylinder 3, and a second sliding cylinder 8 slidably disposed inside the first sliding cylinder 3. A connecting cylinder 10 is slidably connected to one end of the second sliding cylinder 8, and the connecting cylinder 10 is fixedly connected to one end of the first connecting pipe 1. Guide grooves 5, second inclined grooves 12, and first inclined grooves 11 are respectively provided on the first sliding cylinder 3, the sliding limiting shell 4, and the second sliding cylinder 8. The guide grooves 5 and the second inclined grooves 12 both extend to the inner sides of the sliding limiting shell 4 and the first sliding cylinder 3. A drive rod 7 is slidably connected to the inner side of the first inclined groove 11, and the drive rod 7 is also connected to the first sliding cylinder 3 and the sliding limiting shell 4. The sliding connection is provided with a limiting plate 6 fixed at one end of the drive rod 7. One side of the limiting plate 6 is in contact with the outside of the sliding limiting shell 4. When the operator needs to separate the first connecting pipe 1 and the second connecting pipe 2, the first inclined groove 11 and the second inclined groove 12 are inclined at opposite angles. The guide groove 5 is used to guide the sliding of the drive rod 7. First, the sliding limiting shell 4 and the first sliding cylinder 3 are held. Then, the sliding limiting shell 4 is rotated, which allows the drive rod 7 to slide in the guide groove 5. At this time, when the drive rod 7 slides, it can use the sliding connection with the first inclined groove 11 and the second inclined groove 12 to make the second sliding cylinder 8 slide with the first sliding cylinder 3, so that the second sliding cylinder 8 and the first sliding cylinder 3 can extend and retract.

[0029] refer to Figure 5 This is the extended state of the second sliding cylinder 8 and the first sliding cylinder 3;

[0030] refer to Figure 6 This is the retracted state of the second sliding cylinder 8 and the first sliding cylinder 3;

[0031] refer to Figure 5 and Figure 6 When the drive rod 7 slides laterally, it will cause the first inclined groove 11 to move downward and the second inclined groove 12 to move upward, thereby enabling the second sliding cylinder 8 and the first sliding cylinder 3 to slide vertically.

[0032] The setting of the limit plate 6 can prevent the drive rod 7 from separating from the sliding lock mechanism;

[0033] It should be noted that both the second sliding cylinder 8 and the first sliding cylinder 3 are hollow, which allows the first connecting pipe 1 and the second connecting pipe 2 to be connected.

[0034] The second sliding cylinder 8 is slidably provided with limiting blocks 9 on both sides, which slide and engage with the inner side of the connecting cylinder 10. The setting of the limiting blocks 9 can limit and engage with the inner side of the connecting cylinder 10 when the second sliding cylinder 8 slides into the connecting cylinder 10, thereby fixing and limiting the connection between the second sliding cylinder 8 and the connecting cylinder 10. The limiting point is only in the limiting slot 13 of the inner wall of the connecting cylinder 10 and the limiting block 9. This not only allows the first connecting pipe 1 and the second connecting pipe 2 to be quickly disassembled, but also reduces the wear of the sliding lock mechanism.

[0035] Furthermore, the inner wall of the connecting cylinder 10 has limit slots 13 on both sides. The limit slots 13 are used to limit the sliding of the limit block 9. The inner wall of the connecting cylinder 10 also has sliding guide slots 14 on both sides. The two sliding guide slots 14 are located directly below the two limit slots 13. The sliding guide slots 14 are used to guide the sliding of the limit block 9. When the limit block 9 slides into the connecting cylinder 10, it first slides into the sliding guide slot 14. When it slides to the connection point between the sliding guide slot 14 and the limit slot 13, the limit block 9 will be compressed by force and then locked into the limit slot 13, thereby completing the connection between the second sliding cylinder 8 and the connecting cylinder 10. Conversely, the second sliding cylinder 8 and the connecting cylinder 10 can be separated.

[0036] Furthermore, the second sliding cylinder 8 has telescopic grooves 801 on both sides for the sliding and retraction of the limiting block 9. One end of the limiting block 9 is fixedly provided with a spring 802, and the other end of the spring 802 is fixedly connected to the inside of the telescopic groove 801. The limiting block 9 can slide with the second sliding cylinder 8 through the telescopic groove 801. At the same time, the setting of the spring 802 can make the limiting block 9 always have telescopicity, thereby achieving the above-mentioned connection effect.

[0037] In this embodiment, as Figures 1-6 As shown, the principle of the endoscope quick cleaning and switching device provided in this embodiment is as follows:

[0038] When the staff needs to separate the first connecting pipe 1 and the second connecting pipe 2, the first inclined groove 11 and the second inclined groove 12 have opposite inclination angles. The guide groove 5 is used to guide the sliding of the drive rod 7. First, the sliding limit shell 4 and the first sliding cylinder 3 are held. Then, the sliding limit shell 4 is rotated, which allows the drive rod 7 to slide in the guide groove 5. At this time, when the drive rod 7 slides, it can use the sliding connection with the first inclined groove 11 and the second inclined groove 12 to make the second sliding cylinder 8 slide with the first sliding cylinder 3, so that the second sliding cylinder 8 and the first sliding cylinder 3 can extend and retract.

[0039] The setting of the limiting block 9 can limit the connection between the second sliding cylinder 8 and the inner side of the connecting cylinder 10 when the second sliding cylinder 8 slides into the connecting cylinder 10. This can fix and limit the connection between the second sliding cylinder 8 and the connecting cylinder 10. The limiting point is only in the limiting slot 13 on the inner wall of the connecting cylinder 10 and the limiting block 9. This not only allows the first connecting pipe 1 and the second connecting pipe 2 to be quickly disassembled, but also reduces the wear of the sliding lock mechanism.
