Description

Technical Field

[0001] This utility model relates to the field of oral treatment technology, specifically to an oral irrigation device. Background Technology

[0002] There are several types of irrigation devices for root canal treatment, including those with syringes and root canal irrigation needles. These devices use the piston of the syringe to push the irrigation fluid into the root canal through the connected root canal irrigation needle. The fluid's impact force and dissolving properties are used to flush out infected material and debris from the root canal. They are simple to operate and have low cost.

[0003] Existing oral irrigation devices still have the following problems when in use: the speed and pressure of the cleaning fluid supply are difficult to control. When manually pushing the syringe plunger, it is difficult to accurately control the speed and pressure of the cleaning fluid supply. If the cleaning fluid supply speed is too fast or the pressure is too high, it may cause discomfort to the patient. If the speed is too slow, the cleaning fluid may remain in the syringe, affecting the accuracy of the amount of cleaning fluid supplied. Utility Model Content

[0022] Please see Figures 1-4In this embodiment of the present invention, an oral irrigation device includes an irrigation mechanism 2, which includes a connecting frame 21. A syringe tube 22 is fixedly installed at the front end of the connecting frame 21. The irrigation mechanism 2 is equipped with a cleaning fluid supply control mechanism 1, which includes a piston 112 slidably connected to the syringe tube 22. A push rod 111 is fixedly connected to the center of the top of the piston 112. A pressure plate 16 is fixedly connected to the top of the push rod 111. A double-screw drive mechanism is configured at both ends of the pressure plate 16. The double-screw drive mechanism includes a drive motor 17. A controller is provided at the front end of the drive motor 17, and a control panel is provided at the front end of the controller. The whole device adopts... The optimized cleaning fluid supply control structure features an electronically driven push rod 111 with a U-shaped seat 11 containing a pressure plate 16. The pressure plate 16 is driven to rise and fall by a twin-screw drive mechanism, ensuring smooth lifting and lowering. This allows the push rod 111 to smoothly push down the piston 112, ejecting the cleaning fluid from the syringe tube 22 through the root canal irrigation needle 24. The speed and pressure of the cleaning fluid supply can be precisely adjusted via the control panel of the twin-screw drive mechanism controller. Specific parameters can be set on the control panel according to the different root canal irrigation and treatment needs, ensuring the stability and accuracy of the cleaning fluid supply process.

[0023] The syringe tube 22 has a lower interface 23 at its bottom end. A root canal irrigation needle 24 is screwed onto the outside of the lower interface 23. The tail end of the root canal irrigation needle 24 is equipped with a scale and a positioning mark. The root canal irrigation needle 24 is a positioning mark needle. The addition of scale and positioning mark on the tail end of the irrigation needle makes it easier for doctors to accurately judge the depth of the needle entering the root canal. In addition, the upper threaded sleeve of the root canal irrigation needle 24 is screwed onto the outside of the lower interface 23 of the syringe tube 22 to reduce the leakage of irrigation fluid at the lower interface 23 of the syringe tube 22.

[0024] A U-shaped seat 11 is fixedly connected to the top of the connecting frame 21. The center of the upper and lower side walls of the U-shaped seat 11 is provided with a mating groove 12. The two ends of the upper and lower side walls of the U-shaped seat 11 are provided with an installation groove 13. A gripping frame 110 is fixedly connected to each end of the U-shaped seat 11. Doctors can use the gripping frame 110 to move and use the entire oral cleaning device.

[0025] The syringe tube 22 is fixedly connected in the lower mating groove 12, and the drive motor 17 is fixedly installed in the upper mating groove 12. The double screw drive mechanism includes a bearing 14 fixedly installed in the mounting groove 13. The inner rings of the two bearings 14 on the same side are fixedly sleeved with the same screw 15. The drive shaft at the bottom of the drive motor 17 is fixedly connected to a drive gear 18. Each end of the drive gear 18 meshes with a driven gear 19. The driven gear 19 is fixedly sleeved on the outside of the screw 15 on its corresponding side. A through groove is opened between the upper and lower side walls of the pressure plate 16. A threaded sleeve is fixedly installed in the through groove. The threaded sleeve is threadedly connected to the outside of the screw 15 on its corresponding side. The drive motor 17 can drive the drive gear 18 to rotate, thereby driving the driven gear 19 meshing with the drive gear 18 to rotate. The two screws 15 rotate synchronously, in the same direction and at the same speed, which can drive the pressure plate 16 to rise and fall smoothly.

[0026] The working principle of this utility model is as follows: Doctors can use the handheld frame 110 to move and use the overall oral cleaning device. The root canal irrigation needle 24 is a positioning mark needle, with scales and positioning marks added to the tail end of the irrigation needle to help doctors more accurately judge the depth of the needle entering the root canal. After insertion into the root canal, the drive motor 17 can drive the active gear 18 to rotate, which in turn drives the driven gear 19 meshing with the active gear 18 to rotate. The two screws 15 rotate synchronously in the same direction and at the same speed, which can drive the pressure plate 16 to rise and fall smoothly. The smooth rise and fall of the pressure plate 16 can smoothly push the push rod 111 connected to it to press down the piston 112, spraying the cleaning fluid in the syringe tube 22 through the root canal irrigation needle 24 to perform the root canal irrigation work for root canal treatment. The working state of the drive motor 17 can be precisely adjusted through the control panel of the twin screw drive mechanism controller, thereby controlling the speed and pressure of the cleaning fluid supply. According to the root canal irrigation and treatment needs of different root canal treatments, specific parameters can be set on the control panel to ensure the stability and accuracy of the cleaning fluid supply process.
