TECHNICAL FIELD

[0001] The utility model relates to oral surgery technical field, concretely relates to a kind of oral surgery handpiece and the fixed connection device of navigation barrel. BACKGROUND

[0002] Dental handpiece is a kind of high-frequency high-speed or low-speed handheld power instrument, usually composed of handpiece (built-in turbine or motor), handle (for doctors to hold), connecting end (connects air source / power supply to provide power), and is usually cylindrical or cylindrical, which needs to be used with drill (dental surgery cutting tools, such as drill bit, milling cutter, etc.), and is the core tool for precise cutting, drilling or trimming of dental, alveolar bone, bone fragments and other tissues in oral clinical surgery.

[0003] The operation space of oral surgery is very small, and once the handpiece deviates from the plan, it may cause damage to oral tissues or nerves, deviation of implant position, etc., so dental handpiece needs navigation positioning assistance to upgrade the surgical operation from relying on the experience of doctors to precise and controllable digital execution.

[0004] During oral surgery navigation, the handpiece needs to be stably connected with the navigation positioning device to ensure accurate positioning during surgery and ensure surgical results. The traditional connection and fixing method has many defects: the clamp is difficult and unstable to connect with the navigation positioning device, and is prone to looseness or deviation during surgery, resulting in insufficient positioning accuracy; the connection device is too large in size, which affects the feeling of the operator and thus interferes with the flexibility of surgical operation.

[0007] Further, the hole edge of the threaded hole is provided with a rounded corner structure.

[0008] Further, the jackscrew is evenly distributed along the circumference of the positioning sleeve.

[0009] Further, the front end of the positioning sleeve is in the shape of a truncated cone with a smaller front end and a larger rear end.

[0010] Further, the rear end of the positioning sleeve is in threaded connection with the navigation barrel, the navigation barrel is through from front to back, and the rear end of the mobile phone is arranged in the navigation barrel.

[0011] Further, the navigation barrel is a regular octagonal prism, and each side face is printed with an Aruco code.
