[0022] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Embodiment 1

[0024] See also Figure 1-4 The present invention discloses a lacrimal cystonasal anastomosis drill, comprising a curved tube 1, one side of the surface of which is fixedly connected to a handle 2; an adjusting component is arranged inside the curved tube 1, the adjusting component comprises a limiting plate 3, the limiting plate 3 is fixedly connected to the top of the inner cavity of the curved tube 1, a pushing plate 4 is slidably connected inside the limiting plate 3, a vertical plate 5 is fixedly connected to one side of the top of the pushing plate 4, and a handle 6 is fixedly connected to the top of the vertical plate 5; a disinfection component is arranged at one end of the curved tube 1, the disinfection component comprises a disinfection lamp 7, the disinfection lamp 7 is fixedly connected to one side of the inner wall of the curved tube 1, a connecting plate 8 is fixedly connected to one end of the curved tube 1, and a threaded groove 9 is provided on the surface of the connecting plate 8.

[0025] Specifically: the handle 2 can provide a comfortable grip for medical staff, the limit plate 3 can support and limit the push plate 4, the vertical plate 5 can drive the push plate 4 to move, the disinfection lamp 7 can disinfect and sterilize the drill bit 11, and the connecting plate 8 can facilitate the disassembly of the sleeve 12. Through the setting of the disinfection component, not only can the stains on the surface of the drill bit 11 be removed, but it can also be disinfected and sterilized.

[0026] Embodiment 2

[0027] See also Figure 1-4On the basis of the first embodiment, a movable plate 10 is slidably connected to one side of the inner cavity of the curved tube 1, the bottom of the movable plate 10 is fixedly connected to one side of the pushing plate 4, a drill bit 11 is fixedly connected to the top of the movable plate 10, a sleeve 12 is provided on the surface of the connecting plate 8, a threaded tooth 13 is fixedly connected to the inner wall of the sleeve 12, the sleeve 12 is threadedly connected to the surface of the connecting plate 8 through the threaded tooth 13, a rubber plate 14 is fixedly connected to one side of the inner cavity of the sleeve 12, a through groove is provided between the curved tube 1 and the handle 2, the vertical plate 5 is slidably connected to the inside of the through groove, a sliding groove is provided inside the limit plate 3, and the pushing plate 4 is slidably connected to the inside of the sliding groove, the pushing plate 4 is made of polypropylene, and is used to push the movable plate 10 to move through the pushing plate 4, and can adapt to the tortuosity inside the curved tube 1, and the handle 2 is made of plastic, and is used to provide a comfortable grip to reduce the fatigue of the doctor during the operation.

[0028] Specifically: a sliding groove is provided inside the movable plate 10. The setting of the sliding groove can prevent the movable plate 10 from colliding with the disinfection lamp 7. The drill bit 11 can establish a channel between the lacrimal sac and the nasal cavity to improve the excretion of tears. The cooperation of the threaded teeth 13 and the threaded groove 9 can facilitate the replacement of the sleeve 12 to increase the practicality during use. One end of the rubber plate 14 is fixedly connected to the inner wall of the sleeve 12. The rubber plate 14 has sufficient elasticity. When the drill bit 11 contacts the rubber plate 14, the rubber plate 14 will be deformed. At the same time, its own elasticity will make it fit closely with the surface of the drill bit 11, so as to remove impurities on the surface of the drill bit 11. The sliding groove can facilitate the movement of the push plate 4. Polypropylene has sufficient toughness and can well adapt to the tortuosity inside the curved tube 1.

[0029] The working principle of the present invention is as follows: when a drilling operation is required, the medical staff inserts the curved tube 1 deep into the nasal cavity, and when it moves to the drilling position, the drill bit 11 is started through an external controller, and then the medical staff pushes the handle 6 to move, the handle 6 drives the vertical plate 5 to move, the vertical plate 5 drives the push plate 4 to move, the push plate 4 drives the movable plate 10 to move, and the movable plate 10 drives the drill bit 11 to move, so as to facilitate the medical staff to manually adjust the depth of the drilling, thereby improving the operating accuracy and flexibility of the operation and ensuring precise control during the operation.

[0030] When the drill bit 11 needs to be cleaned and disinfected, the user drives the vertical plate 5 to move through the handle 6, thereby driving the drill bit 11 to retract through the movable plate 10, and the rubber plate 14 can scrape off the stains attached to the surface of the drill bit 11 when the drill bit 11 retracts, and then store it into the curved tube 1. At the same time, the disinfection lamp 7 inside the curved tube 1 is started to disinfect and sterilize the surface of the drill bit 11, thereby ensuring the hygiene and safety of the drill bit 11 before each use, which can not only improve the cleaning efficiency of the equipment, but also reduce the tedious steps of manual cleaning, thereby enhancing the sterility protection during the operation.
