[0002] The mobile phone drill bit is a working head on an oral medical instrument. It is a device specially used for oral cleaning and tooth grinding. It is made of tool steel with high hardness, high wear resistance and high heat resistance to make a tough and efficient drill bit.

[0003] During operation, the drill bit generates a significant amount of heat when in contact with the tooth. An assistant must simultaneously inject saline solution into the drilling area (surgical area) for cooling. The assistant also needs to hold a suction device to draw out the saline solution from the surgical area to expose the surgical field for easier observation and operation. Therefore, such surgical procedures typically require two assistants to assist the surgeon, resulting in a certain degree of manpower waste.

[0004] Publication number CN218870516U discloses an oral surgery device accessory, comprising a handpiece mounted on an oral and maxillofacial surgical power system and a nozzle connected to the handpiece via a connector. The nozzle's nozzle faces the drill bit at the front of the handpiece, and the nozzle's tail end is connected to a fluid supply device. This utility model addresses the inconvenience of prior art requiring an assistant to cool the surgical area during surgery using a handpiece. This device allows a single person to perform both the handpiece's drilling and the cooling of the surgical area.

[0005] In the above technical solution, although the prior art achieves the convenience of cooling the drilling and grinding surgical area during single-person operation by using a mobile phone drill bit for surgery, in actual use, when the drill bit rotates at high speed to grind teeth, debris will still be generated in the patient's mouth. For this reason, we provide a mobile phone drill bit with a protective cover. Utility Model Content

Example 2

[0025] In addition to all the technical features of the first embodiment, the present embodiment also includes: the rear end of the mounting rod 2 is fixedly connected to the first clamping block 3, the fixed limiting ring 4 is sleeved on the outer wall of the mounting rod 2, the outer peripheral surface of the bearing ball 5 is provided with a fixed block mounting hole 18, the outer wall surface of the fixed block mounting hole 18 is installed with a protective cover fixing block 16, the first protective cover 6 and the protective cover fixing block 16 are an integrated structure, the interior of the protective cover fixing block 16 is provided with a fixed block fixing hole 19, the internal threads of the fixed block fixing hole 19 and the fixed block mounting hole 18 are installed with a fixed block limiting nail 17, which is passed through the fixed block mounting hole 18. The design of the fixing block fixing hole 19 and the fixing block limiting pin 17 allows the user to flexibly adjust the disassembly and replacement of the first protective cover 6 according to surgical needs to adapt to different surgical environments and needs. The outer wall surface of the fixed limiting ring 4 is provided with a limiting ring fixing hole 11, and the internal threads of the limiting ring fixing hole 11 and the first fixing hole 9 are installed with the first limiting pin 7, and the internal threads of the third fixing hole 12 and the second fixing hole 10 are installed with the second limiting pin 8. Through the design of the first limiting pin 7 and the second limiting pin 8, multiple locking of the mobile phone drill bit is achieved, ensuring safety and stability during the operation.

[0026] Working principle:

[0027] First, the user connects the first clamping block 3 at the rear end of the mounting rod 2 to the main shaft of the mobile phone drill to ensure the mobile phone drill bit is stably fixed to the device. Next, by rotating the first fixing pin 15 on the mounting rod 2, it fits tightly into the first mounting hole 13 and second mounting hole 14 inside the first grinding head 1, firmly securing the first grinding head 1 to the mounting rod 2. This design not only ensures the stability of the drill bit during surgery but also facilitates quick drill bit replacement when needed.

[0028] Next, the user places the fixed stop ring 4 on the outer wall of the mounting rod 2 and locks it to the first fixing hole 9 on the mounting rod 2 using the first stop pin 7. When necessary, the first grinding head 1 and the mounting rod 2 can be easily replaced by removing the first stop pin 7. Subsequently, the front end of the bearing ball 5 is connected to the first protective cover 6, while the rear end is locked to the third fixing hole 12 and the second fixing hole 10 of the fixed stop ring 4 using the second stop pin 8. This structure ensures the stability of the bearing ball 5 while allowing the first protective cover 6 to rotate and adjust to a certain angle.

[0029] Next, the operator installs the shield fixing block 16 onto the outer periphery of the bearing ball 5 through the fixing block mounting hole 18 and securely connects the shield fixing block 16 to the first shield 6 using the fixing block retaining pin 17. This design allows the operator to easily remove and replace the first shield 6 according to surgical needs, adapting to different surgical environments and requirements. During the entire surgical procedure, if the first shield 6 or first grinding head 1 needs to be replaced with a different specification, simply remove the fixing block retaining pin 17 from the fixing block fixing hole 19.

[0030] When the handpiece drill bit begins operating, the high-speed rotation of the drill bit can generate debris in the patient's mouth. The presence of the first protective shield 6 effectively traps this debris within the shield, preventing it from flying around in the patient's mouth and ensuring a safe and clean surgical procedure. Furthermore, the presence of the bearing balls 5 and the fixed stop ring 4 ensures the stability and reliability of the handpiece drill bit during high-speed rotation, reducing surgical risks associated with improper operation or equipment failure.
