Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a catheter for adenoidectomy, comprising a catheter body 1, one end of the catheter body 1 extending into a connecting groove 2, the connecting groove 2 being formed on one side surface of a connecting seat 3, the other end of the catheter body 1 passing through a through groove 5, the through groove 5 being formed on the bottom surface of a stand block 6, a stand block 6 being connected to the top surface at both ends of the connecting seat 3, a movable plate 7 being connected to the inner surface at the top of the stand block 6, a movable groove 8 being formed inside the middle of the movable plate 7, a spring 9 being connected to the inner surface of the movable groove 8, both ends of the spring 9 being in contact with a movable insertion rod 10, the other end of the movable insertion rod 10 passing through one side surface of the movable plate 7, a pressure block 13 being connected to the bottom surface of the movable plate 7, and sliders 16 being connected to both sides of both ends of the movable plate 7, one end of the slider 16 extending into a sliding groove 17 formed on the inner surface of the stand block 6, the slider 16 forming a sliding connection with the stand block 6 through the sliding groove 17.

[0023] Preferably, a fixing bolt 4 is threaded through the bottom surface of the connecting seat 3, and one end of the fixing bolt 4 extends into the connecting groove 2 and contacts one end of the conduit body 1.

[0024] In practical use, when one end of the catheter body 1 is inserted into the connecting groove 2, the fixing bolt 4 is screwed onto the connecting seat 3, so that one end of the fixing bolt 4 can come into contact with the catheter body 1, thereby squeezing and fixing one end of the catheter body 1 into the connecting groove 2. When the fixing bolt 4 is unscrewed, one end of the catheter body 1 can be separated from the connecting groove 2.

[0025] Preferably, the size of the through groove 5 matches the size of the conduit body 1, and the conduit body 1 is slidably connected to the upright block 6 through the through groove 5.

[0026] In actual use, the catheter body 1 can slide through the through groove 5 on the upright block 6.

[0027] Preferably, the movable rod 10 forms an elastic structure with the movable plate 7 through the movable groove 8 and the spring 9.

[0028] In practical use, when the movable rod 10 slides on the movable plate 7, it can elastically extend and retract on the movable plate 7 through the movable groove 8 and the spring 9.

[0029] Preferably, the movable insertion rod 10 extends through one end of the movable plate 7 into the first insertion hole 11. The first insertion hole 11 is opened on the inner surface of the top of the upright block 6, and a second insertion hole 12 is also opened on the inner surface of the upright block 6 at the lower end of the first insertion hole 11. The movable insertion rod 10 is slidably connected to the upright block 6 through the first insertion hole 11 or the second insertion hole 12.

[0030] In practical use, one end of the movable insert rod 10 has an inclined surface facing downwards. Pushing the movable insert rod 10 downwards allows the upright block 6 to press the movable insert rod 10, allowing the movable insert rod 10 to move. When the movable insert rod 10 slides into the first insertion hole 11, the pressure block 13 at the bottom of the moving plate 7 does not contact the conduit body 1. At this time, the conduit body 1 can slide normally in the through groove 5. When the movable insert rod 10 slides into the second insertion hole 12, the pressure block 13 at the bottom of the moving plate 7 will press and fix one end of the conduit body 1 onto the connecting seat 3.

[0031] Preferably, a toggle block 14 is connected to the top surface of one end of the movable rod 10. One end of the toggle block 14 passes through the toggle groove 15 opened on the top surface of the movable plate 7, and the toggle block 14 and the movable plate 7 are slidably connected through the toggle groove 15.

[0032] In practical use, when the toggle block 14 moves within the toggle groove 15, the toggle block 14 can drive the movable rod 10 to slide within the movable groove 8. By pinching the two toggle blocks 14 together, the two movable rods 10 can be moved simultaneously.

[0033] Working principle: When using this adenoidectomy catheter, one end of the catheter body 1 is pre-inserted into the connecting groove 2, and the tightened fixing bolt 4 is fixed in the connecting groove 2. During adenoidectomy, the other end of the catheter body 1 is then passed through the patient's nasal cavity and oral cavity. After passing through the oral cavity, the other end of the catheter body 1 is passed through the through groove 5 on the upright block 6. At this time, the moving plate 7 slides inside the upright block 6, and the sliders 16 on both sides of the moving plate 7 also slide in the sliding grooves 17. This restricts the movement trajectory of the movable plate 7, ensuring that the movable plate 7 can move vertically. The protruding movable rods 10 on both sides of the movable plate 7 are then pressed by the upright block 6, causing one end of the movable rod 10 to press against the spring 9 in the movable groove 8. This causes one end of the movable rod 10 to retract into the movable plate 7, separating it from the first insertion hole 11. When the movable rod 10 moves to the position of the second insertion hole 12, the spring 9 will elastically push the movable rod 10 to move, allowing the movable rod 10 to... The movable plate 7 is inserted into the second insertion hole 12, thus fixing its position. At this time, the pressure block 13 will press and fix the other end of the catheter body 1 onto the connecting seat 3. This operation conveniently completes the fixing of the catheter body 1, preventing operators from using tools or manually tying knots at both ends of the catheter body 1, thus facilitating the use of the catheter body 1 during adenoidectomy. After the adenoidectomy is completed, the actuating block 14 can slide within the actuating groove 15, allowing the two actuating blocks 14 to move closer together. When the lever 14 is turned, the movable insert 10 will press the spring 9 in the movable groove 8, so that one end of the movable insert 10 can be separated from the second insertion hole 12. At this time, the moving plate 7 will be moved upward, so that the pressure block 13 will no longer press and fix the catheter body 1. In this way, the other end of the catheter body 1 can be pulled out from the patient's nasal cavity and oral cavity. Then, the fixing bolt 4 will be unscrewed, so that one end of the catheter body 1 can be separated from the connecting groove 2, so that the catheter body 1 and the connecting seat 3 can be separated and disinfected for reuse.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
