[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1, in this embodiment, as Figures 1 to 13 As shown, this embodiment provides a root canal file flexibility detection device, which includes: an X-axis moving mechanism 1, a Y-axis moving mechanism 2, a clamping mechanism 3 and a detection mechanism 4; wherein the Y-axis moving mechanism 2 is movably arranged on the X-axis moving mechanism 1, and the clamping mechanism 3 is movably arranged on the Y-axis moving mechanism 2; the X-axis moving mechanism 1 drives the Y-axis moving mechanism 2 and the clamping mechanism 3 to move in the X-axis direction, and the Y-axis moving mechanism 2 drives the clamping mechanism 3 to move in the Y-axis direction, so that the clamping mechanism 3 clamps the root canal file 5 and extends into the detection mechanism 4; the detection mechanism The detection mechanism 4 bends the inserted root canal file 5 to perform fatigue detection. When the root canal file 5 is broken in the detection mechanism 4, the clamping mechanism 3 pushes the clamping segment root canal file 5 to continue to extend into the detection mechanism 4 until the clamping segment root canal file 5 and the broken segment root canal file 5 are misaligned in the detection mechanism 4, so that the spiral working part 51 on the clamping segment root canal file 5 and the spiral working part 51 on the broken segment root canal file 5 generate misalignment friction, and the clamping mechanism 3 drives the clamping segment root canal file 5 to move out of the detection mechanism 4, and the clamping segment root canal file 5 brings out the broken segment root canal file 5 through the misalignment friction.

[0043] In this embodiment, the spiral working portion 51 on the root canal file 5 is configured in a flexible spiral conical shape.

[0044] In this embodiment, the detection mechanism 4 is used to perform a two-stage fatigue detection on the root canal file 5, which can improve the detection effect. At the same time, the clamping section root canal file 5 and the broken section root canal file 5 can be dislocated in the detection mechanism 4. The spiral working part 51 on the clamping section root canal file 5 and the spiral working part 51 on the broken section root canal file 5 generate a dislocation friction force to directly bring the broken root canal file 5 out of the detection mechanism 4. The root canal file 5 can be taken out without disassembling the detection mechanism 4, thereby improving the detection efficiency.

[0045] In this embodiment, the detection mechanism 4 includes: a detection block 41, a limit assembly 42 and a misalignment assembly 43; a detection channel 411 is opened on the detection block 41, the limit assembly 42 is movably installed in the front section of the detection channel 411, and the misalignment assembly 43 is movably installed in the rear section of the detection channel 411; the clamping mechanism 3 clamps the root canal file 5 and extends into the detection channel 411, and the root canal file 5 passes through the limit assembly 42 and the misalignment assembly 43 in sequence, the limit assembly 42 movably limits the root canal file 5 in the front section of the detection channel 411, and the root canal file 5 bends in the rear section of the detection channel 411 to perform the first level fatigue detection, until the front end of the root canal file 5 abuts against the rear end of the detection channel 411, The clamping mechanism 3 continues to push the root canal file 5 to move in the detection channel 411, and the spiral working part 51 of the root canal file 5 pushes the dislocation component 43 to open in the rear section of the detection channel 411, and the spiral working part 51 of the root canal file 5 is bent in the dislocation component 43 to perform the second-level fatigue detection; when the spiral working part 51 of the root canal file 5 is broken in the rear section of the detection channel 411, the limiting mechanism is deflected under the drive of the clamping section root canal file 5, and then drives the spiral working part 51 of the clamping section root canal file 5 to push the dislocation component 43 to open in the rear section of the detection channel 411, until the spiral working part 51 of the clamping section root canal file 5 and the spiral working part 51 of the broken section root canal file 5 are dislocated in the dislocation component 43.

[0046] In this embodiment, the detection block 41 plays a role of installation, and the limiting component 42 can move in the front section of the detection channel 411. Since the root canal file 5 is made of flexible material and is set in a gradual size, that is, the diameter of the root canal file 5 gradually increases from the front end to the rear end, the root canal file 5 passes through the limiting component 42 and is slowly locked by the limiting component 42. The rear section of the detection channel 411 is set in an arc shape, which can bend the spiral working part 51 of the root canal file 5 to achieve the first level fatigue detection of the root canal file 5. After locking the root canal file 5, the limiting component 42 will also move with the root canal file 5 in the front section of the detection channel 411. The limiting component 42 will deflect when it moves to a certain position. At the same time, since the front section of the root canal file 5 is against the rear end of the detection channel 411, the root canal file 5 cannot continue to move. At this time, the root canal file 5 can only bend. The positioning component 43 is movably arranged at the rear section of the detection channel 411. The dislocation component 43 opens under the push of the root canal file 5, and can provide the displacement of the secondary bending of the root canal file 5, that is, to realize the second-level fatigue detection of the root canal file 5, which can improve the effect of detecting the fatigue of the root canal file 5, and after the root canal file 5 is broken, the dislocation component 43 provides the displacement of the spiral working part 51 of the clamping section root canal file 5 and the spiral working part 51 of the broken section root canal file 5, so that the spiral working part 51 of the clamping section root canal file 5 and the spiral working part 51 of the broken section root canal file 5 are displaced, so that the spiral working part 51 of the clamping section root canal file 5 can hook the spiral working part 51 of the broken section root canal file 5, which is convenient for pulling the clamping section root canal file 5 and the broken section root canal file 5 out of the detection channel 411, without the need to disassemble the detection mechanism 4, thereby improving the detection efficiency.

[0047] In this embodiment, the limiting assembly 42 includes: a limiting ring 421, a first limiting unit 422 and a second limiting unit 423; the limiting ring 421, the first limiting unit 422 and the second limiting unit 423 are movably installed at the front section of the detection channel 411, and the first limiting unit 422 and the second limiting unit 423 are movably connected to the limiting ring 421 respectively; the root canal file 5 passes through the limiting ring 421 until the first limiting unit 422 and the second limiting unit 423 respectively press into two clamping grooves on the root canal file 5, so that the limiting ring 421, the first limiting unit 422 and the second limiting unit 423 clamp the root canal file 5; when the spiral working part 51 of the root canal file 5 is broken at the rear section of the detection channel 411, the limiting ring 421, the first limiting unit 422 and the second limiting unit 423 are deflected in the detection channel 411, thereby driving the clamping section root canal file 5 to deflect.

[0048] In this embodiment, the first limiting unit 422 and the second limiting unit 423 cooperate with the limiting ring 421 to position and straighten the root canal file 5 and lock the root canal file 5 at the same time.

[0049] In this embodiment, a flexible deflection ring 424 is disposed in the gap between the limiting ring 421 and the detection channel 411 .

[0050] In this embodiment, by providing the flexible deflection ring 424 , it is possible to realize both horizontal sliding of the limit ring 421 in the detection channel 411 and deflection of the limit ring 421 in the detection channel 411 .

[0051] In this embodiment, the first limiting unit 422 includes: a first movable column 4221 and a first limiting column 4222; the second limiting unit 423 includes: a second movable column 4231 and a second limiting column 4232; the front section of the detection channel 411 is provided with a first trapezoidal groove 412 and a second trapezoidal groove 413, one end of the first movable column 4221 is movably connected with the first straight side and the first bevel side of the first trapezoidal groove 412, the first movable column 4221 is movably connected with the limiting ring 421, the other end of the first movable column 4221 is provided with a first installation groove, the first limiting column 4222 is movably arranged in the first installation groove, one end of the second movable column 4231 is movably connected with the second straight side and the second bevel side of the second trapezoidal groove 413 The first movable column 4231 is movably connected to the first and second movable columns 4231, and the second movable column 4232 is movably arranged in the second mounting groove; a turning unit 425 is also arranged in the first trapezoidal groove 412; the root canal file 5 passes through the limiting ring 421, and the first movable column 4221 and the second movable column 4231 are respectively pressed into the two slots on the root canal file 5, and the first movable column 4221 and the second movable column 4231 are respectively moved along the first straight side of the first trapezoidal groove 412 and the second oblique side of the second trapezoidal groove 413 by the drive of the root canal file 5, and when the first movable column 4221 enters the turning unit 425 to roll, the limiting ring 421 is driven to deflect.

[0052] In this embodiment, the first limiting column 4222 and the second limiting column 4232 play the role of locking the root canal file 5 in the limiting ring 421 and positioning it. At the same time, after the limiting ring 421 and the root canal file 5 are locked, the root canal file 5 can be prevented from jumping. The first moving column 4221 and the second moving column 4231 can guide the limiting ring 421 to move horizontally and deflect in the detection channel 411.

[0053] In this embodiment, the first limiting column 4222 is connected to the first movable column 4221 in the first installation groove through an elastic member, and the second limiting column 4232 is connected to the second movable column 4231 in the second installation groove through an elastic member.

[0054] In this embodiment, the outer wall of the first movable column 4221 is surrounded by a plurality of axially arranged gear racks 4223 ; the flip unit 425 includes: a plurality of flip racks 4251 ; each gear rack 4223 on the first movable column 4221 is meshed with each flip rack 4251 .

[0055] In this embodiment, the first movable column 4221 rolls with each flip rack 4251 through each rack bar 4223. At the same time, the first movable column 4221 is relatively slidably connected with the limit ring 421 through each rack bar 4223. Therefore, when the first movable column 4221 rotates, it can drive the limit ring 421 to deflect, thereby driving the root canal file 5 to deflect.

[0056] In this embodiment, a limiting spring 427 and a limiting plate 426 are disposed in the second trapezoidal groove 413 to facilitate the second movable column 4231 to return to its original position in the second trapezoidal groove 413 .

[0057] In this embodiment, since the spiral working portion 51 of the clamping segment root canal file 5 is misaligned with the spiral working portion 51 of the broken segment root canal file 5, when the two are pulled out of the detection channel 411, the first movable column 4221 and the second movable column 4231 are still respectively pressed into the two grooves on the root canal file 5, and the second movable column 4231 pushes the limit spring 427 against the limit plate 426 until a height difference is formed between the handrail of the root canal file 5 and the entrance of the detection channel 411, so as to facilitate breaking the handrail of the root canal file 5 and the body of the root canal file 5, and reuse the handrail of the root canal file 5.

[0058] In this embodiment, the first straight side and the first oblique side of the first trapezoidal groove 412 are provided with a first limiting groove, and the second straight side and the second oblique side of the second trapezoidal groove 413 are provided with a second limiting groove; the end of the first movable column 4221 is connected to the first limiting groove through a first ball, a first elastic member and a first limiting block, and the end of the second movable column 4231 is connected to the second limiting groove through a second ball, a second elastic member and a second limiting block.

[0059] In this embodiment, the first limiting groove and the second limiting groove can be ball grooves, and the first limiting block and the second limiting block can also be rollers, which does not affect the horizontal movement and rolling of the first movable column 4221 and the second movable column 4231.

[0060] In this embodiment, the dislocation component 43 includes: a dislocation plate 431; the dislocation plate 431 is movably arranged at the rear section of the detection channel 411; the dislocation plate 431 is pushed toward the inner wall of the detection channel 411 when the root canal file 5 is bent, and when the spiral working part 51 of the root canal file 5 is broken at the rear section of the detection channel 411, the spiral working part 51 of the clamping section root canal file 5 and the spiral working part 51 of the broken section root canal file 5 are dislocated between the dislocation plate 431 and the inner wall of the detection channel 411.

[0061] In this embodiment, the offset plate 431 is connected to the rear section of the detection channel 411 through an elastic member. When the offset plate 431 is pushed open, the spiral working portion 51 of the clamping section root canal file 5 and the spiral working portion 51 of the broken section root canal file 5 are offset, and pulling out is achieved through the friction between the two.

[0062] In this embodiment, the X-axis moving mechanism 1 includes: an X-axis moving pair 11, an X-axis slider 12 and an X-axis motor 13; the X-axis slider 12 is movably installed on the X-axis moving pair 11, and the output part of the X-axis motor 13 is connected to the X-axis slider 12; the X-axis motor 13 pushes the X-axis slider 12 to move on the X-axis moving pair 11.

[0064] In this embodiment, the clamping mechanism 3 includes: a clamping block 31 ; the clamping block 31 is fixed on the Y-axis slider 22 , and a clamping hole is formed on the clamping block 31 for clamping the root canal file 5 .

[0065] Embodiment 2, based on embodiment 1, this embodiment provides a detection method using the root canal file flexibility detection device provided in embodiment 1, comprising: driving the Y-axis moving mechanism 2 and the clamping mechanism 3 to move in the X-axis direction by the X-axis moving mechanism 1, and driving the clamping mechanism 3 to move in the Y-axis direction by the Y-axis moving mechanism 2, so that the clamping mechanism 3 clamps the root canal file 5 and extends it toward the detection mechanism 4; bending the inserted root canal file 5 by the detection mechanism 4 to perform fatigue detection, when the root canal file 5 is broken in the detection mechanism 4, the clamping mechanism 3 pushes the clamping segment root canal file 5 to continue to extend into the detection mechanism 4, until the clamping segment root canal file 5 and the broken segment root canal file 5 are misaligned in the detection mechanism 4, so that the spiral working part 51 on the clamping segment root canal file 5 and the spiral working part 51 on the broken segment root canal file 5 generate misalignment friction, and the clamping mechanism 3 drives the clamping segment root canal file 5 to move out of the detection mechanism 4, and the clamping segment root canal file 5 brings the broken segment root canal file 5 out by the misalignment friction.
