Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a gastroscope that facilitates the replacement of the positioning cannula. Background Technology

[0002] Gastroscopy is a medical examination method, and also refers to the instrument used in this examination. Gastroscopy can directly observe the actual condition of the examined area, and can further clarify the diagnosis by performing pathological biopsy and cytological examination on suspicious lesions. It is the preferred examination method for upper gastrointestinal tract diseases. It uses a thin, flexible tube inserted into the stomach, allowing doctors to directly observe lesions in the esophagus, stomach, and duodenum, especially for small lesions.

[0003] Traditional methods of installing endoscopic positioning cannulas are often complex in structure. The installation process requires a lot of time for precise alignment and fixation of components, and the disassembly process is even more cumbersome, which may involve multiple tools and multiple steps. This not only reduces work efficiency but also increases the workload of medical staff. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a gastroscope with an easy-to-replace positioning cannula, solving the problem that traditional gastroscope positioning cannula installation methods are often complex in structure, require a lot of time for precise alignment and fixation of components during installation, and are even more cumbersome in disassembly, potentially involving multiple tools and steps. This not only reduces work efficiency but also increases the workload of medical staff.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A gastroscope with a convenient positioning cannula includes a gastroscope head and a positioning cannula. A first connector is fixedly installed at the lower end of the gastroscope head, and a second connector is fixedly installed at the upper end of the positioning cannula. The gastroscope head and the positioning cannula are connected together by the first connector and the second connector. An inner groove is formed at the lower end of the first connector, and a first sliding groove and a second sliding groove are symmetrically formed on the side wall of the first connector. The two second sliding grooves are respectively located above the two first sliding grooves.

[0007] Preferably, a sealing ring is slidably installed inside the inner groove, and connecting blocks are symmetrically fixedly installed on the side wall of the sealing ring, with the two connecting blocks slidably installed in the two first sliding grooves respectively.

[0008] Preferably, each of the two second grooves has a wedge-shaped block slidably installed inside, each of the two wedge-shaped blocks has a fixed column slidably installed inside, and each of the two fixed columns is fixedly installed in the inner wall of the inner groove.

[0009] Preferably, each of the two fixed columns is fitted with a spring, and the two springs are respectively fixedly connected to the inner wall of the inner groove and the two wedge blocks.

[0010] Preferably, the second connector has symmetrical slots and strip grooves on its side wall, and the two slots and strip grooves are connected to each other.

[0011] Preferably, a slide bar is slidably installed inside each of the two strip grooves, and a threaded ring is threadedly installed on the surface of the second connector, the threaded ring being rotatably installed in the two slide bars.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. During installation, the first connector can be inserted into the second connector. At this time, the wedge block will slide into the second groove under the pressure. The wedge block will slide on the fixed column and compress the spring. When the wedge block slides to the position that is directly opposite the slot, the spring will restore its deformation and drive the wedge block to spring into the slot to complete the snap-fit ​​installation. When disassembly is required, the threaded ring on the second connector can be rotated. The rotation of the threaded ring will drive the slide bar to move upward in the strip groove. At this time, the slide bar will push the wedge block to slide in the second groove. The wedge block will then slide back from the slot into the first connector to release the locking state and complete the disassembly. This makes the installation and disassembly of the positioning sleeve more convenient when using the device, and greatly improves the efficiency of the preparatory work for gastroscopy.

[0014] Second, the rotation of the threaded ring will drive the slide bar to slide downward in the strip groove. At this time, the slide bar will squeeze the connecting block, and the connecting block will be subjected to the squeezing force to exert the squeezing force on the sealing ring. At this time, the sealing ring will undergo slight deformation, sealing the connection between the first connecting piece and the second connecting piece, improving the sealing performance of the connection and enhancing the safety of gastroscopy.

[0021] This application provides a gastroscope with a convenient positioning cannula replacement method, effectively solving the problems of traditional gastroscope positioning cannula installation methods, which are often complex in structure, require a lot of time for precise alignment and fixation of components during installation, and are even more cumbersome in disassembly, potentially involving multiple tools and steps. This not only reduces work efficiency but also increases the workload of medical staff. During installation, the first connector is inserted into the second connector. At this time, the wedge block is squeezed and slides into the second groove. The wedge block slides on the fixing post and compresses the spring. When the wedge block slides to the position directly opposite the slot, the spring will restore its deformation, causing the wedge block to spring into the slot and complete the snap-fit ​​installation. When disassembly is required, the threaded ring on the second connector can be rotated. The rotation of the threaded ring will drive the slide bar to move upward inside the strip groove. At this time, the slide bar will push the wedge block to slide inside the second groove. The wedge block will then slide back from the slot into the first connector to release the locking state, completing the disassembly. This makes the installation and disassembly of the positioning cannula more convenient during use, greatly improving the efficiency of the preparatory work for gastroscopy. Example

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problem that traditional gastroscopy positioning cannula installation methods are often complex in structure, requiring a lot of time for precise alignment and fixation of components during installation, and the disassembly process is even more cumbersome, possibly involving multiple tools and multiple steps. This not only reduces work efficiency but also increases the workload of medical staff. The overall idea is as follows: A gastroscopy with easy-to-replace positioning cannula includes a gastroscope head 11 and a positioning cannula 12. A first connector 13 is fixedly installed at the lower end of the gastroscope head 11, and a second connector 14 is fixedly installed at the upper end of the positioning cannula 12. The gastroscope head 11 and the positioning cannula 12 are connected by a first connector 13. A connector 13 and a second connector 14 are connected together. The lower end of the first connector 13 has an inner groove 15. Symmetrically, a first sliding groove 16 and a second sliding groove 17 are formed on the side wall of the first connector 13. The two second sliding grooves 17 are located above the two first sliding grooves 16. A sealing ring 18 is slidably installed inside the inner groove 15. Connecting blocks 19 are symmetrically fixedly installed on the side wall of the sealing ring 18. The two connecting blocks 19 are slidably installed in the two first sliding grooves 16. Wedge-shaped blocks 21 are slidably installed inside each of the two second sliding grooves 17. Fixing posts 22 are slidably installed inside each of the two wedge-shaped blocks 21. The two fixing posts 22 are fixedly installed in the inner wall of the inner groove 15. Springs 23 are fitted onto each fixed post 22. Two springs 23 are fixedly connected to the inner wall of the inner groove 15 and two wedge blocks 21, respectively. The second connecting member 14 has symmetrically formed slots 24 and strip grooves 25 on its side wall. The two slots 24 and strip grooves 25 are connected. Sliding strips 26 are slidably installed inside each of the two strip grooves 25. A threaded ring 27 is threaded onto the surface of the second connecting member 14. The threaded ring 27 is rotatably installed in the two sliding strips 26. During installation, the first connecting member 13 can be inserted into the second connecting member 14. At this time, the wedge blocks 21 are subjected to compressive force and slide into the second sliding groove 17. The wedge blocks 21 will then slide on the fixed post 22 and compress the springs 23. When the wedge block 21 slides to the position directly opposite the slot 24, the spring 23 will restore its deformation, causing the wedge block 21 to spring into the slot 24 to complete the snap-fit ​​installation. When disassembly is required, the threaded ring 27 can be rotated on the second connector 14. The rotation of the threaded ring 27 will drive the slide bar 26 to move upward inside the strip groove 25. At this time, the slide bar 26 will push the wedge block 21 to slide inside the second slide groove 17. The wedge block 21 will then slide back from the slot 24 into the first connector 13 to release the locking state and complete the disassembly. This makes the installation and disassembly of the positioning sleeve 12 more convenient when using the device, greatly improving the efficiency of the preparatory work for gastroscopy.After installation, the threaded ring 27 can be rotated downwards. The rotation of the threaded ring 27 will cause the slide bar 26 to slide downwards in the groove 25. At this time, the slide bar 26 will press against the connecting block 19. The connecting block 19, under pressure, applies pressure to the sealing ring 18. The sealing ring 18 will then undergo slight deformation, sealing the connection between the first connecting member 13 and the second connecting member 14, improving the sealing performance of the connection and enhancing the safety of the gastroscopy.

[0023] To address the problems existing in the prior art, this utility model provides a gastroscope with an easy-to-replace positioning cannula. During installation, the first connector 13 can be inserted into the second connector 14. At this time, the wedge block 21 will slide into the second slide groove 17 under the pressure. The wedge block 21 will slide on the fixed post 22 and compress the spring 23. When the wedge block 21 slides to the position directly opposite the slot 24, the spring 23 will restore its deformation, causing the wedge block 21 to spring into the slot 24 to complete the snap-fit ​​installation. When disassembly is required, the threaded ring 27 can be rotated on the second connector 14. The rotation of the threaded ring 27 will drive the slide bar 26 to move upward inside the strip groove 25. At this time, the slide bar 26 will push the wedge block 21 to slide inside the second slide groove 17. The wedge block 21 will then slide back from the slot 24 into the first connector 13 to release the locking state and complete the disassembly. This makes the installation and disassembly of the positioning cannula 12 more convenient during use, greatly improving the efficiency of the preparatory work for gastroscopy.

[0024] Working principle:

[0025] In the first step, during installation, the first connector 13 can be inserted into the second connector 14. At this time, the wedge block 21 will slide into the second slide groove 17 under the pressure. The wedge block 21 will slide on the fixed post 22 and compress the spring 23. When the wedge block 21 slides to the position directly opposite the slot 24, the spring 23 will restore its deformation and drive the wedge block 21 to spring into the slot 24 to complete the snap-fit ​​installation. When disassembly is required, the threaded ring 27 can be rotated on the second connector 14. The rotation of the threaded ring 27 will drive the slide bar 26 to move upward inside the strip groove 25. At this time, the slide bar 26 will push the wedge block 21 to slide inside the second slide groove 17. The wedge block 21 will slide back from the slot 24 into the first connector 13 to release the locking state and complete the disassembly. This makes the installation and disassembly of the positioning sleeve 12 more convenient when using the device, and greatly improves the efficiency of the preparatory work for gastroscopy.

[0026] In the second step, after installation, the threaded ring 27 can be rotated downwards. The rotation of the threaded ring 27 will drive the slide bar 26 to slide downwards in the strip groove 25. At this time, the slide bar 26 will squeeze the connecting block 19. The connecting block 19 is subjected to the squeezing force and applies the squeezing force to the sealing ring 18. At this time, the sealing ring 18 will undergo slight deformation, sealing the connection between the first connecting member 13 and the second connecting member 14, improving the sealing performance of the connection and enhancing the safety of gastroscopy.

[0027] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
