[0019] Example 1
[0020] like Figure 1-5 As shown, the first embodiment of the present invention is a turning needle suitable for use under low-speed conditions of an oral electric motor, including an oral low-speed motor 1 which is a dental 1:5 speed-increasing curved handpiece with an internal waterway of 1:1 and a low-speed oral electric motor of Yusen External Fast Equipment of Konami Medical, the oral low-speed motor 1 having a rotating shaft 11, and the turning needle is installed on the rotating shaft 11, so as to facilitate oral treatment.
[0021] The current oral low-speed motor-mounted burs on the market are inconvenient to install and replace, and are not easy to install and replace different types of burs according to usage needs, and their installation stability is poor. This application uses two different bur structures that can be installed according to usage needs. The bur has a needle bar that can be inserted into the rotating shaft through a needle tube and screwed onto an externally threaded sleeve adhered to the rotating shaft by an internally threaded sleeve, making it convenient and stable to install and replace.
[0022] The oral low-speed motor 1 has a rotating shaft with an external thread sleeve 12, and the turning needle is screwed into the external thread sleeve 12, so that it is convenient to replace turning needles of different shapes.
[0023] One of the needle structures in this embodiment comprises a pointed needle 21, which includes a needle head 31 and a needle shaft 32. The needle head of the pointed needle 21 is a tapered needle head. The needle shaft 32 is embedded with a needle tube 33 that is inserted into the rotating shaft. The needle shaft 32 has a hexagonal structure and is half the length of the needle tube 33. An internal threaded sleeve 34 is provided within the needle tube 33, which is screwed onto the external threaded sleeve 12. The internal threaded sleeve and the external threaded sleeve are installed in conjunction with each other, and the needle tube and the rotating shaft are installed in conjunction with each other. The tapered needle head has a fine spray hole (not shown).
[0024] Another turning needle structure in this embodiment is that the turning needle includes a round-headed turning needle 3, and the round-headed turning needle 3 includes a needle head 31 and a needle rod 32. The needle rod 32 is embedded with a needle tube 33 that is inserted into the rotating shaft 11. The needle rod is a hexagonal structure, and the length of the needle tube 33 is half the length of the needle rod 32. An internal threaded sleeve 34 is provided inside the needle tube 33 and is screwed onto the external threaded sleeve 12. The needle rod 32 included in the round-headed turning needle 3 is provided with a connecting rod 35 at one end, and a round head 36 is provided at the outer end of the connecting rod 35. The length of the connecting rod 35 is shorter than the length of the needle rod 32. The internal threaded sleeve is installed in conjunction with the external threaded sleeve, and the needle tube is installed in conjunction with the rotating shaft. The round head is provided with a fine spray hole (not shown in the figure).
[0025] Working principle: Figure 1 and 2 As shown, the use of oral low-speed motors requires certain professional knowledge of the equipment and needles, and the doctor must receive professional training and operation guidance. During use, hygiene and disinfection should be carried out, and different speeds and powers should be adjusted to suit different treatment needs.
[0026] The oral low-speed motor has an external threaded sleeve on the end of the shaft. A pointed needle or a round needle can be used according to different usage needs. The needle tube of the pointed needle or the round needle is inserted into the shaft and the internal threaded sleeve installed in the needle tube is screwed onto the external threaded sleeve.
[0027] Using an oral low-speed motor allows for faster and more effective treatment of oral problems, saving time and effort. Due to its precise rotation and control, the use of an oral low-speed motor eliminates the uncertainties associated with manual operation, reducing hand injuries and oral pain. The oral low-speed motor can more precisely control the rotation and vibration of the bur, enabling doctors to more accurately treat oral problems and improve treatment outcomes. Because the oral low-speed motor's rotation ensures stable operation, it reduces motor failure and doctor hesitation, improving work efficiency and treatment quality.
[0028] It should be noted that the above preferred embodiments are only to illustrate the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and it cannot limit the protection scope of the present application. Any equivalent changes or modifications made in accordance with the spirit and essence of the present application shall be covered within the protection scope of the present application.
