Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1-3, for the root canal file steering driver of the utility model discloses and the root canal file adaptive thereto, including a handle 2, the handle 2 is a hollow tubular structure, a micro motor 3, an internal power supply, a transmission rod 4 and a gear train are arranged in the handle 2, the micro motor 3 is fixedly arranged at the end of the handle 2, the gear train is arranged at the head end of the handle 2, the transmission rod 4 is arranged between the micro motor 3 and the gear for power transmission, the gear train comprises a bevel gear 5 and a fluted disc 6, the bevel gear 5 is coaxially fixed at the end of the transmission rod 4, the fluted disc 6 is rotatably arranged in the handle 2, a threaded post 7 is coaxially fixed below the fluted disc 6, the bevel gear 5 is meshed with the fluted disc 6, an included angle is formed between the transmission rod 4 and the threaded post 7, a spring button 9 is arranged at the end of the handle 2, the spring button 9, the micro motor 3 and the internal power supply are connected in series, the micro motor 3 is powered by an internal power supply, the switch of the micro motor 3 is controlled by the spring button 9, when the spring button 9 is pressed, the circuit is connected, the micro motor 3 is started, the gear disc 6 is driven to rotate synchronously by the transmission rod 4 and the helical gear 5, the spring button 9 is loosened, the spring button 9 automatically resets, the circuit is disconnected, the micro motor 3 is closed, and the gear disc 6 stops rotating.
Coaxial being fixed with screw thread post 7 on the terminal surface under fluted disc 6, screw thread post 7 stretches out handle 2 and screw thread post 7 and handle 2 between have certain contained angle, root canal file 1 is including twisting section and column section, twist section and column section integrated into one piece, set up the ring channel 10 of indent on the outer wall of column section, the maximum torque that ring channel 10 bore is less than the maximum torque that the twisting section bore, thereby when bearing too big moment of torsion, can be in ring channel 10 department initiative fracture, be convenient for take out cracked root canal file 1, the inside screw hole 8 that is equipped with of column section, screw hole 8 and screw thread post 7 looks adaptation, during the use, root canal file 1 corresponds the spiro union on screw thread post 7, the direction that simultaneously root canal file 1 was screwed up is the same with the rotation direction of fluted disc 6, thereby make root canal file 1 at the during operation, can further screw up along with rotating, not hard up phenomenon can not appear.
