The current root canal preparation means is to adopt root canal therapy instrument and machine root canal instrument to cooperate. The during operation, root canal therapy appearance drives the apparatus and is rotary motion in the root canal, cuts the root canal inner wall through the cutting part of apparatus to reach the moulding purpose of root canal, its power is generally provided by the electromagnetic motor. Its advantages are high shaping efficiency, high shaping effect, and low working strength of operator. This is because the working portion of the endodontic instrument has a certain taper and a thread distributed thereon, and the working portion needs to have a certain cross-sectional shape in order to form a cutting edge. Because the cutting angle of the root canal file is generally large due to the limitation of the radial size of the root canal file instrument and the restriction of a processing means, the cutting of the root canal file to the wall of the root canal is basically carried out in a rubbing mode, which inevitably causes the extrusion and the frictional heat of the instrument to the wall of the root canal.
When the rotary type root canal therapy machine is used for preparing the root canal, organic matters on the wall of the root canal can be modified by heat generated by the friction of the instrument, and dentin scraps, dentin tubule effluence, saliva, bacteria and the like are attached to the inner wall of the root canal under the action of the drilling and grinding pressure of the instrument to form a staining layer with the thickness of about 1-2 microns. The smear layer may block the collateral canal, hindering penetration of the drug into the lateral wall of the canal and the dentinal tubules, resulting in the incomplete filling of the collateral canal. If the smear layer is not completely removed, it will lead to an increased failure rate of the treatment and increased complications, directly affecting the treatment effect. The resulting smear layer needs further cleaning. Therefore, the common method for clinical root canal preparation is to shape the root canal by using a rotary root canal therapy machine, and then remove the smear layer and clean the root canal after the shaping is completed. If can realize the root canal file apparatus in the cutting of root canal internal rotation, the additional has little vibration, and this will increase the chip removal ability of root canal file apparatus, is showing and is reducing cutting resistance and cutting temperature, effectively avoids the production in smear layer, improves the quality that the root canal was prepared, reduces operator's intensity of labour.

The impact piston 102 is in a dynamic sealing engagement with the inner wall of the piston cylinder 103, such that an upper piston chamber is formed between the upper end cap 104 and the impact piston 102, and a lower piston chamber is formed between the lower end cap 105 and the impact piston 102. An upper air hole 103-1 and a lower air hole 103-2 are respectively arranged on the side wall of the piston cylinder 103 at the positions corresponding to the upper piston cavity and the lower piston cavity.
The upper end cover 104 is provided with a step 104-2, the step 104-2 is provided with a bearing 104-3, and a bearing outer ring of the bearing 104-3 is provided with a driven gear 106. The driven gear 106 is free to rotate relative to the upper end cap 104. A key slot hole 106-1 is formed at the upper end of the driven gear 106, the key wheel 101-4 is in clearance fit with the key slot hole 106-1, and the key wheel 101-4 can axially slide in the key slot hole 106-1.
When the impact piston 102 is excited to vibrate up and down, the impact piston impacts the upper limit sleeve 101-2 and the lower limit sleeve 101-3, so that the main shaft 101 is driven to vibrate. When the driven gear 106 is driven by external power to rotate, the driven gear 106 drives the main shaft 101 to rotate together through the matching between the key slot hole 106-1 and the key wheel 101-4, so that the main shaft 101 is vibrated and rotated simultaneously.
As shown in fig. 4, the rotation driving mechanism 2 includes an input shaft 201, a driving gear 202, and an outer sleeve 203, the input shaft is connected to the outer sleeve 203 through a bearing, and one end of the input shaft 201 is connected to the driving gear 202.
As shown in fig. 5, the bush 3 is provided with a space 301 so that the driving gear 202 can be engaged with the driven gear 106. A first air guide groove 302 and a second air guide groove 303 are formed in the side wall of the liner 2. The bush 3 is tightly fitted outside the piston cylinder 103 of the movement 1.
When the air conditioner is installed, the upper end position 302-1 of the first air guide groove corresponds to the upper air hole 103-1 of the piston cylinder 103, and the lower end position 303-1 of the second air guide groove corresponds to the lower air hole 103-2 of the piston cylinder 103.
As shown in fig. 6 to 8, the housing 4 includes a handpiece cavity 401 and a handle cavity 402, and a first air passage 403 and a second air passage 404 are provided in the handle of the housing 4. The combination of the movement 1 and the bush 3 is mounted in a handpiece cavity 401, the rotary drive mechanism 2 is fixedly mounted in a handle cavity 402 through an outer sleeve 203, and a drive gear 202 of the rotary drive mechanism 2 is engaged with a driven gear 106 of the movement, forming a fitting structure shown in fig. 1.
When installed, the clearance 301 of the bushing 3 corresponds in position to the shank cavity 402 of the housing 4. The lower end position 302-2 of the first air guide groove of the liner 3 corresponds to the position of the first air passage 403, and the upper end position 303-2 of the second air guide groove corresponds to the position of the second air passage 404. Therefore, the first air passage 403 and the second air passage 404 are respectively communicated with the air passages of the upper air hole 103-1 and the lower air hole 103-2 of the piston cylinder 103.
When pressure gas enters from the second air channel 404, the gas enters the lower piston cavity of the movement 1 through the second gas guide groove 303 and the lower gas hole 103-2; at the moment, the air in the piston cavity on the movement 1 enters the first air guide groove 302 from the upper air hole 103-1 and is exhausted through the first air channel 403. Under the driving of the pressure difference between the upper piston and the lower piston, the impact piston 102 moves upwards to impact the upper limit sleeve 101-2, and drives the main shaft 101 to move upwards. When the pressure gas is reversely fed from the first air passage 403, the pressure gas enters the upper piston cavity of the movement 1 through the first air guide groove 302 and the upper air hole 103-1, drives the impact piston 102 to move downwards, and impacts the lower limit sleeve 101-3 to drive the main shaft 101 to move downwards. Reciprocating in this way, the vibration of the movement main shaft 101 is realized.
When torque is input into the input shaft 201, the driving gear 202 rotates to drive the driven gear 106 to rotate; since the key wheel 101-4 of the main shaft 101 is in keyed engagement with the key slot hole 106-1 of the driven gear 106, rotation of the driven gear 106 will cause the main shaft 101 to rotate together.
In operation, when alternating pressure gas is input into the first gas passage 403 and the second gas passage 404, and torque is input into the input shaft 201, the main shaft 101 vibrates and rotates simultaneously.
By adopting the technical scheme, the vibration impact force of the impact piston 102 on the main shaft 101 is independent from the external force applied to the main shaft 101, and the vibration of the impact piston 102 is not influenced by the external force. Secondly, torque is transmitted between the driven gear 106 and the main shaft 101 through a sliding key, and the driven gear 106 does not need to vibrate along with the main shaft 101, which is beneficial to the simplification and miniaturization of the structure.
Preferably, the striking piston may be electromagnetically excited. Specifically, when the electromagnetic excitation is adopted, the impact piston 102 is made of a permanent magnet, the bushing 3 may be an electromagnetic induction coil, and the impact piston made of the permanent magnet material may vibrate up and down under the action of an alternating magnetic field of the electromagnetic induction coil to impact the stop collar, so as to drive the spindle to vibrate.
