Description

Technical Field

[0001] This invention relates to the field of dental root canal treatment technology, and in particular to a root canal pulp extraction vacuum adsorption cleaning integrated machine. Background Technology

[0002] In current root canal treatment preparation, the pulp is removed by sequentially using a manual pulp needle, a manual root canal file, and a machine root canal file. Then, a root canal cleaning needle is used to clean the remaining material. Each step is performed separately and takes a lot of time. This process needs to be repeated many times, which is laborious, ineffective, and prone to causing medical accidents. Summary of the Invention

[0003] The present invention aims to solve the above-mentioned defects and provide an integrated machine for root canal pulp extraction and vacuum adsorption cleaning.

[0004] To overcome the deficiencies in the prior art, the technical solution adopted by the present invention to solve its technical problem is: a root canal pulp extraction vacuum adsorption cleaning integrated machine, comprising a bidirectional vacuum pump, a root canal file motor connected to the bidirectional vacuum pump, a motor steer connected to the head of the root canal file motor, a fixing frame sleeved on the motor steer, and a clamping head connected to the motor steer. The bidirectional vacuum pump is connected to the root canal assembly through an inlet pipe and an outlet pipe. The bidirectional vacuum pump generates high-pressure water flow to rinse the pulp and residue in the root canal of the tooth through the inlet pipe and the root canal assembly. The bidirectional vacuum pump generates negative pressure to adsorb the pulp and residue in the root canal of the tooth through the root canal assembly. The root canal assembly is connected to the clamping head after passing through a rotary joint bracket connected to the fixing frame, thereby driving the root canal assembly through the root canal file motor to peel the pulp and other debris from the root canal wall of the tooth.

[0005] Further improvements include the root canal assembly comprising a rotary joint that snaps into a rotary joint bracket 9, a handle axially inserted into the rotary joint, and a hollow tube-structured root canal preparation head inserted into one end of the handle. The other end of the handle is engaged with a clamping head to drive the handle to rotate. The rotary joint has an inlet channel A connected to an inlet pipe and a return channel A connected to a return pipe. The inlet channel A, together with the inlet channel C on the handle and the inlet D on the root canal preparation head, forms an inlet channel. The water flow in the inlet channel peels away the root canal wall. The detached pulp and other debris are rinsed. The return water channel A, together with the return water channel C in the handle and the return water inlet D in the root canal preparation head, form a return water channel. The pulp and other debris detached from the root canal wall are adsorbed through the return water channel and enter the bidirectional vacuum pump. Annular grooves corresponding to the inlet and return water channels C are respectively opened on the handle so that both the return and inlet water channels are in a passable state when the handle is rotated. The surface of the root canal preparation head is provided with a cutting edge, and a cutting head is provided on the free end of the root canal preparation head.

[0006] Further improvements include the use of a helical structure for the cutting blade.

[0007] Further improvements include the use of a triangular cutting blade in the cutting head.

[0008] Further improvements include embedding multiple annular sealing rings on the handle, with the sealing rings located on both sides of the annular groove.

[0009] Further improvements include installing a one-way valve on the mounting bracket, the one-way valve being connected in series between the bidirectional vacuum pump and the root canal assembly via an inlet pipe and a return pipe.

[0010] Further improvements include the following: the one-way valve includes a valve body with an inlet channel B and a return channel B extending through it. A flow-limiting chamber is formed within the valve body, connecting to both the inlet and return channels B. A steel ball and a spring that pushes the steel ball to block the inlet channel B are installed in the flow-limiting chamber connected to the inlet channel B. Water flowing into the inlet channel B pushes the steel ball and compresses the spring, thus opening the inlet channel B. A second steel ball and a second spring that pushes the second steel ball to block the return channel B are installed in the flow-limiting chamber connected to the return channel B. Negative pressure water generated by a bidirectional vacuum pump in the return channel B draws in the second steel ball and compresses the second spring, thus opening the return channel B.

[0011] The beneficial effects of this invention are as follows: This design integrates pulp extraction, root canal preparation, and cleaning into one unit, reducing surgical time, improving root canal treatment effectiveness, treatment quality, efficiency, and reducing root canal treatment costs; the cutting blade and cutting head can peel off the pulp and other debris from the root canal wall, and high-pressure water is injected through the water inlet channel to flush the root canal, while the return water channel uses negative pressure water to adsorb the pulp and other debris peeled off from the root canal wall, thereby realizing pulp extraction, root canal preparation, and cleaning; the sealing ring plays a sealing role, ensuring the stability of water pressure in the water inlet and return channels; the one-way valve ensures unidirectional movement of the water inlet and return channels to prevent backflow.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] according to Figure 1 As shown, a root canal pulp extraction and vacuum adsorption cleaning integrated machine includes a bidirectional vacuum pump 1, a root canal file motor 2 connected to the bidirectional vacuum pump 1, a motor steer 3 connected to the head of the root canal file motor 2, a fixing frame 4 sleeved on the motor steer 3, and a clamping head 5 connected to the motor steer 3. The bidirectional vacuum pump 1 is connected to the root canal assembly through an inlet pipe 11 and an outlet pipe 10. The bidirectional vacuum pump 1 generates high-pressure water flow to flush the pulp and residue in the root canal of the tooth through the inlet pipe 11 and the root canal assembly. The bidirectional vacuum pump 1 generates negative pressure to adsorb the pulp and residue in the root canal of the tooth through the root canal assembly. The root canal assembly passes through a rotary joint bracket 9 connected to the fixing frame 4 and is connected to the clamping head 5. Thus, the root canal assembly is driven by the root canal file motor 2 to peel the pulp and other debris from the root canal wall of the tooth. The root canal file motor 2 can provide power to the root canal assembly.

[0021] By adopting the above-described implementation method, pulp removal, root canal preparation, and cleaning are integrated into one, which improves the effect, quality, and efficiency of root canal treatment and reduces the cost of root canal treatment. This device is simple to operate, easy to accept, saves treatment time, improves efficiency, cleans thoroughly, and enhances treatment effect.

[0022] according to Figure 2 , Figure 3 As shown, the root canal assembly includes a rotary joint 7 that snaps into a rotary joint bracket 9, a handle 12 that axially extends into the rotary joint 7, and a hollow tube-structured root canal preparation head 6 that extends into one end of the handle 12. The other end of the handle 12 is engaged with a clamping head 5 to drive the handle 12 to rotate. The rotary joint 7 has an inlet channel A14 connected to the inlet pipe 11 and a return channel A21 connected to the return pipe 10. The inlet channel A14, together with the inlet channel C26 on the handle 12 and the inlet D28 on the root canal preparation head 6, forms an inlet channel. The water flow in the inlet channel peels away the root canal wall. The removed pulp and other debris are rinsed. The return water channel A21, the return water channel C25 opened in the handle 12, and the return water port D27 opened on the root canal preparation head 6 form a return water channel. The pulp and other debris peeled off from the root canal wall are adsorbed through the return water channel and enter the bidirectional vacuum pump 1. Annular grooves 22 corresponding to the inlet water channel C26 and the return water channel C25 are opened on the handle 12 respectively, so that the return water channel and the inlet water channel are in a passable state when the handle 12 is in the rotating state. The surface of the root canal preparation head 6 is provided with a cutting blade 23, and a cutting head 24 is provided on the free end of the root canal preparation head 6.

[0023] Using the above-described embodiments, the root canal assembly of this structure, with its cutting blade 23 and cutting head 24 on the root canal preparation head 6, can peel off the pulp and other debris from the root canal wall. High-pressure water is injected through the water inlet channel to rinse the root canal, while the water return channel uses negative pressure water to absorb the pulp and other debris peeled off from the root canal wall, thus integrating pulp removal, root canal preparation, and cleaning into one unit.

[0024] according to Figure 4 and Figure 5 As shown, the cutting blade 23 adopts a spiral structure; the cutting head 24 adopts a triangular cutting disc. The above-described implementation method is conducive to quickly peeling off the dental pulp and residue in the root canal and draining them from the root canal.

[0025] Multiple annular sealing rings 13 are embedded on the handle 12. The sealing rings 13 are located on both sides of the annular groove 22. The sealing rings 13 seal the water inlet channel and the water return channel to prevent water from overflowing from the rotary joint 7 during water inlet and return. The sealing rings 13 can also ensure the water pressure between the water inlet channel and the water return channel.

[0026] according to Figure 3As shown, a one-way valve 8 is installed on the mounting bracket 4. The one-way valve 8 is connected in series between the bidirectional vacuum pump 1 and the root canal assembly via an inlet pipe 11 and a return pipe 10. The one-way valve 8 includes a valve body 15, in which an inlet channel B17 and a return channel B18 are formed. A flow-limiting chamber 19 is formed in the valve body 15, which is connected to the inlet channel B17 and the return channel B18 respectively. A steel ball 29 and a spring 16 that pushes the steel ball 29 to block the inlet channel B17 are installed in the flow-limiting chamber 19 connected to the inlet channel B17. When water flows into the inlet channel B17, it pushes the steel ball 29 to compress the spring 16, thus putting the inlet channel B17 into a passable state. The flow-limiting chamber 19, which is connected to the return channel B18, is equipped with a steel ball 20 and a spring 30 that pushes the steel ball 20 to block the return channel B18. The negative pressure generated by the bidirectional vacuum pump 1 in the return channel B18 sucks up the steel ball 20 and compresses the spring 30, thereby putting the return channel B18 into a passable state. By adopting the above implementation method, unidirectional flow of water inlet and return is achieved, avoiding backflow during water inlet and return.

[0027] Working principle: Before operation, the bidirectional vacuum pump 1 needs to be connected to the water supply pipe, and the handle 12 of the root canal preparation head 6 needs to be fixed in the middle hole of the clamping head 5. After preparation, when working, first insert the root canal preparation head 6 into the root canal hole of the tooth, turn on the switch on the root canal file motor 2, and then turn on the switch of the bidirectional vacuum pump 1. Normal operation can then begin. When the root canal file motor 2 is working, it drives the root canal preparation head 6 to rotate in the root canal of the tooth, which can peel off the pulp and other debris from the root canal wall. The water inlet pipe 11 of the bidirectional vacuum pump 1 pumps out high-pressure water. When the high-pressure water flows through the one-way valve 8, it pushes open the steel ball 29, passes through the water inlet channel A14, and then enters the water inlet channel C26 and the corresponding annular groove 22 on the handle 12. It then flows out through the water inlet D28 of the root canal preparation head 6 and through the hollow tube hole of the root canal preparation head 6, and flows out at the cutting head 24. This washes away the debris peeled off from the root canal wall and other debris, thus achieving a cleaning effect.

[0028] Subsequently, by switching the solenoid valve in the bidirectional vacuum pump 1, the inlet pipe 11 is closed and the return pipe 10 is opened. At this time, due to the connection of the vacuum tube of the bidirectional vacuum pump 1, a large negative pressure is generated in the return pipe 10. When the negative pressure passes through the one-way valve 8, it draws open the steel ball 20 and compresses the spring 30. The water in the root canal passes through the hollow tube of the root canal preparation head 6, through the return water channel C25 on the handle 12 and the corresponding annular groove 22, and finally through the return water channel B18 in the one-way valve 8. At this time, a negative pressure is generated in the hollow tube of the root canal preparation head 6, which peels off the root canal wall and other debris and adsorbs them, thus achieving the cleaning effect.

[0029] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
