Description

Technical Field

[0001] This invention belongs to the field of medical devices and relates to a dental medical device, specifically a root canal cleaning device that integrates suction and washing, which can facilitate root canal treatment by physicians and improve the success rate of root canal treatment surgery. Background Technology

[0002] Laser technology is an emerging technology in dentistry. Studies have shown that water and hydroxyapatite have the strongest absorption of 2940nm erbium-yttrium aluminum garnet (Er:YAG) lasers, which can generate strong cavitation effects and shock waves, significantly improving root canal cleaning. With further technological advancements, research has employed laser-activated root canal irrigation technology. This involves placing a fiber optic tip at the root canal opening and releasing low-energy, ultrashort pulses of laser light into the cleaning solution. This creates cavitation bubbles within the root canal, and the explosion of these bubbles generates strong photoacoustic shock waves, causing the cleaning solution to flow at high speed, thus effectively cleaning the root canal.

[0003] With the advancements in computer science, mathematics, and other fields, artificial intelligence (AI) has become a strategic technology leading a new round of technological revolution and industrial transformation. In recent years, leveraging its advantages in memory, learning ability, and processing speed, AI technology has been increasingly applied in medical diagnosis, with machine learning algorithms and other AI technologies finding wide application in areas such as intelligent image recognition and diagnosis, and intelligent treatment.

[0004] However, in actual treatment, existing medical devices still have some limitations: separating laser cleaning, cleaning fluid delivery, and extraction increases the difficulty of operation for doctors; secondly, doctors cannot easily observe the specific tooth condition and position when performing surgery in the narrow environment of the oral cavity. In addition, while doctors have a relatively large space for left-right swinging during the operation of the handpiece, the space for adjusting the pitch is very limited, and the angle adjustment between the working end of the handpiece and the root canal greatly affects the efficiency of the doctor's operation. Therefore, the existing technology designs the handpiece as a two-section design, using a folding handpiece to improve the flexibility of the working end's posture adjustment to a certain extent. However, the two sections of the handpiece are ultimately fixed, so the improvement in flexibility is limited. Furthermore, the handpiece cannot be made into a complex movable structure, so the only way to improve the flexibility of the handpiece operation is to look at other technical aspects. Summary of the Invention

[0005] To address the aforementioned problems, the present invention aims to design an integrated root canal cleaning device that combines suction and rinsing. This integrated approach allows for convenient delivery and extraction of cleaning solution, while also enabling doctors to clearly observe the oral cavity environment via a display screen, facilitating surgical treatment.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A root canal cleaning device that integrates extraction and rinsing, comprising:

[0008] The handle includes a gripping part and an operating part for extending into the patient's oral cavity;

[0009] An infusion tubing, installed inside the handle, is used to deliver the cleaning solution;

[0010] The suction tube, installed inside the handle, is used to suction out cleaning waste liquid;

[0011] The laser tube, installed inside the handle, is used to provide laser for root canal cleaning;

[0012] The infusion tube, the aspiration tube, and the laser tube together form an integrated tube bundle; the front end of the integrated tube bundle is bent downward and extends laterally from the front end of the operating part of the handle to form a working end; the middle part of the integrated tube bundle is installed in the handle through a support tube, and at least the part of the integrated tube bundle extending from the front end of the support tube is an elastic tube with a certain deformation capacity.

[0013] The fine-tuning component is used to pull the working end of the integrated tube bundle upwards to fine-tune the position of the working end of the integrated tube bundle.

[0014] Preferably, the adjustment assembly includes a slider, a second fixing member, and a slide groove provided along the length of the handle. The slider is freely slidably installed in the slide groove. The slider is connected to the traction rope through the second fixing member. A locking mechanism is provided between the slider and the slide groove. The slider at least partially protrudes from the handle to form an operation button. The operation button can drive the slider to slide in the slide groove, thereby realizing the traction of the traction rope. The locking mechanism can lock the position of the slider in the slide groove at any time.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention adopts an integrated extraction and washing design, which saves space and improves operational accuracy, thereby indirectly improving work efficiency.

[0017] This invention incorporates a fine-tuning component that allows the operator to manually adjust the pitch of the working end while simultaneously manipulating the handle. This significantly expands the operational flexibility of the root canal cleaning device, reduces cleaning time, and improves work efficiency. Attached Figure Description

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] The present invention will be described in detail below with reference to specific embodiments, which will help users to further understand the present invention.

[0029] like Figure 1 As shown, the present invention provides a root canal cleaning device that integrates extraction and washing, including...

[0030] Handle 1 includes a gripping part 102 and an operating part 101 for extending into the patient's oral cavity;

[0031] The infusion tube 4 is installed inside the handle 1 and is used to deliver the cleaning solution;

[0032] A suction tube, installed inside handle 1, is used to suction cleaning waste liquid;

[0033] Laser tube 3, installed inside handle 1, is used to provide laser for root canal cleaning;

[0034] The infusion tube 4, the suction tube, and the laser tube 3 together form an integrated tube bundle 19; the front end of the integrated tube bundle 19 is bent downward and extends laterally from the front end of the operating part 101 of the handle 1 to form a working end 20; the middle part of the integrated tube bundle 19 is installed in the handle 1 through the support tube 2, and at least the part of the integrated tube bundle 19 extending from the front end of the support tube 2 is an elastic tube with a certain deformation capacity.

[0035] The fine-tuning component 6 is used to pull the working end 20 of the integrated tube bundle 19 upward to fine-tune the position of the working end 20 of the integrated tube bundle 19.

[0036] It should be noted that the main function of the handle 1 is to facilitate gripping and to internally support the root canal cleaning device. Therefore, the actual shape of the handle 1 remains unchanged, and it can generally be a cavity. For ease of understanding, this embodiment provides a specific structure in which the hand-held part of the handle 1 is a cylindrical shell, and the operating part 101 is an upwardly inclined conical shell with a gradually decreasing diameter. The cylindrical shell and the conical shell can be integrally formed or made separately and then connected. The connection method is not limited and can be screw connection or welding. The specific material used for manufacturing is not limited and can be plastic or metal material, such as stainless steel, aluminum alloy, etc. This is not very relevant to the technical problem solved by this invention and will not be described in detail.

[0037] It should be mentioned that, for ease of operation, the angle between the axis of the conical shell and the axis of the cylindrical shell is set as needed, generally 10-30 degrees. The front end of the conical shell is provided with an opening to facilitate the extension of various pipes. This opening can be of any shape. For example, in some embodiments, it is designed as a cylindrical opening. The pull line of the cylindrical opening is approximately perpendicular to the axis of the conical shell. Generally, an acute angle is preferred, with the angle range being approximately 60-90 degrees. This way, when operating the handle 1, the working end 20 at the front end of the integrated tube bundle 19 has a good operating space.

[0038] As a preferred embodiment, the angle between the cylindrical opening and the axis of the conical shell is approximately 70-80 degrees. At this time, the angle can be changed by pulling up the working end 20 by the fine-tuning component 6, thereby realizing the fine adjustment of the angle of the integrated tube bundle 19, which can expand the operating range and the ability to be at the optimal operating angle during root canal cleaning.

[0039] In a preferred embodiment, the laser tube 3 and the infusion tube 4 are arranged side by side, and the working end 20 of the suction tube is nested inside the working end 20 of the infusion tube 4. Since the suction tube and the infusion tube 4 work alternately and their working ranges highly overlap, the nesting arrangement can greatly improve work efficiency, reduce the space occupied, and greatly improve the ease of operation.

[0040] As a preferred embodiment, the portion of the integrated tube bundle 19 extending from the front end of the support tube 2 is made of thin-walled steel or plastic tube, giving it a certain degree of deformation capability. It should be emphasized that only a small degree of deformation capability is required, and no special materials are needed. Ordinary thin-walled steel or plastic tubes can meet the requirements. In particular, for the laser tube 3, it can be made of soft material and fixed together with the infusion tube 4 and the suction tube by tube clamps. Basically, it is only necessary to ensure that the infusion tube 4 is elastic.

[0041] In some embodiments, a bidirectional pump 9 is also provided at the right tail of the cylindrical housing. The bidirectional pump 9 is a microfluidic pump whose inlet and outlet can be reversed. The bidirectional pump 9 can be any pump that meets the flow requirements in the prior art. The type of pump is not limited. In some embodiments, a bidirectional gear pump can always be used. The left port of the bidirectional pump 9 is connected to the suction tube and the infusion tube 4 via a check valve (not shown in the figure), and the right port is also connected to the cleaning fluid source and the waste fluid tank 18 via a check valve. When cleaning is required, the check valve connected to the infusion tube 4 at the left port of the bidirectional pump 9 is open, and the check valve connected to the suction tube at the left port of the bidirectional pump 9 is closed. At the same time, the check valve connected to the cleaning fluid source at the right end of the bidirectional pump 9 is open, and the check valve connected to the waste fluid tank 18 is closed, allowing cleaning to proceed. The cleaning fluid source continuously flows through the bidirectional pump 9 to the infusion tube 4 and is sprayed out through the working end 20 of the infusion tube 4 for root canal cleaning. When waste fluid needs to be aspirated, the bidirectional pump 9 is reversed, and the check valves are deactivated in the reverse direction. The waste fluid in the root canal is continuously aspirated through the working end 20 of the suction tube and sent to the waste fluid tank 18. Of course, alternative technologies can also be used, such as replacing the bidirectional pump 9 with two pumps, and using two completely independent pipelines for infusion and aspiration.

[0042] In some embodiments, the lower surface of the hand-shaped conical housing is provided with a camera 5 for observation, which can capture images of the root canal to assist doctors in real-time observation.

[0043] In some embodiments, the laser tube 3 is a laser optical path assembly, or it can be a pipe for installing the laser optical path assembly. The laser optical path assembly itself adopts existing technology, and the present invention does not improve this part, so it will not be described in detail.

[0044] In some embodiments, for ease of use and manufacturing, fiber optic lock nuts 7 and fiber optic clips 8 can also be provided in the cylindrical housing to facilitate connection between the laser optical path assembly and the laser generator. In fact, fiber optic lock nuts 7 and fiber optic clips 8 are for facilitating fiber connection and disassembly, which will not be elaborated further.

[0045] In some embodiments, a detachable transmission tube 17 is provided at the tail of the cylindrical housing. Fiber optic cables, water channels, control lines, etc. are centrally installed in the transmission tube 17 and are protected by the transmission tube 17. Generally, the transmission tube 17 is made of a soft tube, such as a PVC pipe similar to an electrical conduit.

[0046] In some embodiments, to fully utilize the root canal cleaning device of the present invention, a control console 11 should also be included. A transmission pipe 17 is directly connected to the control console 11. The control console 11 contains a liquid storage chamber 12, a controller 13, a waste liquid tank 18, an erbium laser 14, and an image processing device 15. A display screen 16 is located on the upper part of the control console 11. The liquid storage chamber 12 serves as the cleaning fluid source and is connected to a bidirectional pump 9 via a water pipe installed within the transmission pipe 17. The waste liquid tank 18 is also connected to the bidirectional pump 9 via a water pipe installed within the transmission pipe 17. The erbium laser 14 is connected via a fiber laser tube 3 installed within the transmission pipe 17. The controller 13 controls the forward and reverse rotation of the bidirectional pump 9, and the image processing device 15 processes the image information captured by the camera 5 and displays it on the display screen 16. It should be noted that when the controller 13 is an industrial control computer or a host computer, the controller 13 and the image processing device 15 can be integrated into a single device.

[0047] In some embodiments, for ease of operation, a working button 10 is provided on the handle 1. The working button 10 is connected to the controller 13 via a signal line. As a manual control method, the working button 10 can be set to two buttons: aspiration and infusion. The information sent by the two buttons is used by the controller 13 to control the bidirectional pump 9 accordingly. Of course, automatic control can also be used. The working button 10 is only set to a start button. After the start signal is sent, the controller 13 controls the bidirectional pump 9 to automatically perform the cleaning work in the workflow of "delivering cleaning fluid - cleaning root canal - withdrawing cleaning fluid". The specific manual mode or automatic mode can be selected as needed. This invention does not make specific limitations.

[0048] In some embodiments, the laser output parameters of the erbium laser 14 are: wavelength 2940nm, pulse frequency 15Hz, pulse width 50μs, energy 20mJ, and output power 0.3W.

[0049] In some embodiments, the fine-tuning component 6 includes a first fixing member 610, a traction rope 620, a steering component 630, and an adjustment component 640 disposed on the grip portion 102 of the handle 1;

[0050] The first fixing member 610 is used to connect the front end or working end 20 of the integrated tube bundle 19 extending out of the support tube 2;

[0051] The traction rope 620 has one end connected to the first fixing member 610, and the other end connected to the adjustment component 640 after being turned by the steering component 630.

[0052] The adjustment component 640 is used to pull or release the traction rope 620.

[0053] In some embodiments, the first fixing member 610 is a buckle composed of two connected fixing rings. The two fixing rings are respectively fitted onto the infusion tube 4 and the laser tube 3 for fixing. The traction rope 620 can be fixed on one of the fixing rings. The traction rope 620 can be made of steel wire rope or high-strength fiber rope, and the specific method is not limited.

[0054] In some embodiments, the steering assembly 630 includes at least a first steering wheel 631 disposed above the first fixing member 610 and a second steering wheel 632 disposed below the adjusting assembly 640. Both the first steering wheel 631 and the second steering wheel 632 can be ordinary fixed pulleys.

[0055] In some embodiments, the adjustment component 640 includes a slider 641, a second fixing member 642, and a groove 643 provided along the length of the handle 1. The slider 641 is freely slidably installed in the groove 643. The slider 641 is connected to the traction rope 620 through the second fixing member 642. A locking mechanism is provided between the slider 641 and the groove 643. The slider 641 protrudes at least partially from the handle 1 to form an operation button 644. The operation button 644 can drive the slider 641 to slide in the groove 643, thereby achieving the traction of the traction rope 620. The locking mechanism can lock the position of the slider 641 in the groove 643 at any time. The second fixing member only realizes the connection between the slider 641 and the traction rope 620. The specific shape is not limited. It is foreseeable that the bottom of the handle 1 housing in the groove 643 must have a groove to facilitate the sliding of the second fixing member 642 through, or the bottom of the groove 643 itself penetrates into the handle 1. The specific shape is not limited.

[0056] In some embodiments, the slider 641 has a mounting cavity 646, and the locking mechanism includes a pressing part 647, a support plate 648, a first sliding post 649, and at least two second sliding posts 650. The support plate 648 is disposed within the mounting cavity 646, and a plurality of locking springs 651 are provided between the bottom of the support plate 648 and the bottom of the mounting cavity 646. The first sliding post 649 is disposed in the middle of the support plate 648, and the top of the first sliding post 649 extends out of the top of the slider 641 and is fixedly connected to the pressing part 647. At least one second sliding post 650 is provided at each end of the support plate 648. The second sliding column 650 extends out of the mounting cavity 646. The top of the second sliding column 650 is provided with a friction surface 645 that contacts the side wall of the slide groove 643. When the pressing part 647 applies pressing force, the support plate 648 compresses the locking spring 651, causing the second sliding column 650 to disengage from the slide groove 643. The slider 641 can slide freely and generate traction force on the traction rope 620 when the operator applies sliding force. When the operator leaves the pressing part 647, the locking spring 651 returns to its original position, so that the top of the second sliding column 650 makes frictional contact with the side wall of the slide groove 643, locking the slider 641 in its current position within the slide groove 643.

[0057] In some embodiments, the cross-sectional shape of the groove 643 is convex, and the slider 641 is also designed in a corresponding convex shape. The second sliding post 650 is disposed on both sides of the slider 641. The two sides of the groove and the top of the second sliding post 650 are in frictional contact. Specifically, the top sidewalls of the two sides of the groove can be processed into a rough surface or a friction layer can be pasted on, such as a sandpaper surface. The top of the second sliding post 650 can not only be set as a rough surface, but also a contact plate can be set. The contact plate is set with a rough surface to increase the friction.

[0058] It should be noted that the present invention only requires a slight upward pull on the integrated tube bundle 19 for adjustment, so no great force is required. Therefore, there is no need for excessive static friction between the second sliding column 650 and the inner top surface of the sliding groove 643. In addition, the locking spring 651 can increase the positive pressure of the friction surface 645. Therefore, no special design is required for the friction surface 645 to meet the locking requirements.

[0059] In use, the reservoir 12 stores a 2.5% sodium hypochlorite solution. The console 11 is powered on, and the dentist observes the oral cavity environment via the display screen 16 on the console 11, locates the area to be cleaned, moves the handle 1 to the working position, and adjusts the posture of the front working end 20 of the integrated canal bundle 19 using the fine-tuning component 6. In automatic mode, pressing the working button 10 on the handle 1 causes the controller 13 to automatically perform the cleaning work according to a preset program, following the workflow of "delivering cleaning solution—cleaning the root canal—extracting cleaning solution." Pressing the button again during the process will temporarily stop the work until the button is pressed again, at which point the cleaning process will resume until the entire cleaning process is complete.

[0060] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The scope of protection of this invention does not involve any improvement to the software and methods.

[0061] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the invention do not depart from the spirit and scope of the invention and should be covered within the scope of the claims of the invention.
