Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a sterile high-definition otorhinolaryngoscope cannula. Background Art

[0002] An endoscope is a detection instrument integrating multiple disciplines, which can enter the body and display the internal state. However, the endoscope needs to be isolated from the human body during use, otherwise it is easy to cause cross-infection. The existing solution is to set a sheath tube as the inspection channel of the endoscope. For example, a disposable endoscope sheath tube disclosed in the application number: 202121658702.0 discloses that a channel for the endoscope to extend into the human body is provided through a body shell, a sheath tube, a first adjusting part and a second adjusting part, and the human body can be isolated from the endoscope; this solution eliminates the disinfection process and can avoid cross-infection, greatly improving the working efficiency of the endoscope; however, this sheath tube is inconvenient to operate, takes a long time to adjust and fix during use, and the fixing effect is limited. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the problems in the background art, and provides a sterile high-definition otorhinolaryngoscope cannula, which has a simple structure, is convenient to use and has a good fixing effect.

[0004] The purpose of the utility model is realized by the following technical solutions:

[0005] A sterile high-definition otorhinolaryngoscope cannula includes a threaded housing, a locking nut and a hose. The locking nut is threadedly connected to the threaded housing. One end of the threaded housing is processed with a plug inserted into the hose. The end of the threaded housing away from the plug is processed with an expansion section. The end of the expansion section is processed with a handle symmetric about the axis of the threaded housing. An elastic groove is processed on the threaded housing between the handles and extends through the expansion section to the middle of the threaded housing. Anti-slip pads are detachably installed on the opposite side walls of the two handles. One end of the hose is connected to the plug, and the other end is installed with a sealing lens.

[0006] The expansion section and the threaded section of the threaded housing are smoothly transitioned.

[0007] The beneficial effects of the sterile high-definition otorhinolaryngoscope cannula provided by the utility model are as follows:

[0008] (1) By setting the threaded housing and the locking nut, and using the elastic groove processed on the threaded housing, after the endoscope tube is installed, by adjusting the position of the locking nut, the endoscope tube can be conveniently fixed by the threaded housing. Compared with fixing the endoscope tube with a tie strap in the prior art, the operation is convenient and the fixing is stable;

[0009] (2) A sealing lens is installed at one end of the hose. The sealing lens can not only isolate the endoscope, but also select sealing lenses of different specifications according to different inspection procedures to improve the accuracy of detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Embodiment

[0017] As Figures 1 to 4As shown in the figure, the sterile high-definition otorhinolaryngoscope cannula provided in this embodiment includes a threaded housing 1, a locking nut 2, and a flexible tube 3. The locking nut 2 is threadedly connected to the threaded housing 1. One end of the threaded housing 1 is processed with a plug 4 inserted into the flexible tube 3. The threaded housing 1 and the flexible tube 3 adopt an insertion installation method, and flexible tubes 3 with different specifications and functions can be selected according to different usage scenarios. The end of the threaded housing 1 away from the plug 4 is processed with an expansion section 5. The end of the expansion section 5 is processed with a handle 6 symmetrical to the axis of the threaded housing 1. The handle 6 is used to facilitate the operator to hold the threaded housing 1. An elastic groove 7 is processed on the threaded housing 1 between the handles 6, and the elastic groove 7 extends through the expansion section 5 to the middle of the threaded housing 1. On the one hand, the expansion section 5 is used to expand the inner diameter of the threaded housing 1 to facilitate the insertion of the endoscope. On the other hand, during the movement of the locking nut 2 towards the expansion section 5, it will contact the outer wall of the expansion section 5 and apply pressure to the expansion section 5, so that the expansion section 5 can lock the insertion part of the endoscope and improve the connection stability. To meet this requirement, the expansion section 5 and the threaded section 10 of the threaded housing 1 are smoothly transitioned. To improve the connection stability, anti-slip pads 8 are detachably installed on the opposite side walls of the two handles 6. The anti-slip pads 8 can be selected to be installed or removed according to the usage situation. One end of the flexible tube 3 is connected to the plug 4, and the other end is installed with a sealing lens 9. The sealing lens 9 is used to ensure the isolated state inside the flexible tube 3. The sealing lens 9 is placed inside the flexible tube 3 by an embedded installation method, which can avoid increasing the diameter of the flexible tube 3 and make the flexible tube 3 have better passability. At the same time, lenses with different functions can be selected according to different application scenarios, and the lenses can be used to increase the clarity of the endoscope imaging.

[0018] The usage method of the present utility model is as follows:

[0019] During use, select the corresponding specification cannula according to different positions. The cannulas are divided into: 1. Diameter 2.7 mm, length 110 mm; 2. Diameter 3 mm, length 140 mm; 3. Diameter 4 mm, length 180 mm. Then install the cannula, and use the cannula to leave an isolation channel in the patient's body to prevent cross-infection caused by the detection of the endoscope tube for different people. Then insert the endoscope tube into the flexible tube 3 from the expansion section 5 until the lens at the end of the endoscope tube abuts against the sealing lens 9. Subsequently, rotate the locking nut 2, and use the locking nut 2 to squeeze the expansion section 5, so that the expansion section 5 of the threaded housing 1 retracts inward and fixes the endoscope tube to ensure the fitting state between the lens and the sealing lens 9. This fixing method is not only simple to operate but also has strong stability. Finally, loosen the locking nut 2 and take out the endoscope. The endoscope can be cleaned by immersing it in a dressing with sterile saline, while the cannula is treated as medical waste.

[0020] The above are only the preferred embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modification and replacement based on the technical solutions and inventive concepts provided by the present utility model should be covered within the protection scope of the present utility model. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present utility model omits the description of well-known components and processing techniques and processes to avoid unnecessarily limiting the present utility model.
