Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an auxiliary device for the treatment of oral and dental pulp diseases. Background Technology

[0002] In the clinical treatment of dental endodontic diseases, auxiliary devices are crucial tools for ensuring treatment efficiency and precision. Their functions cover multiple aspects, including visual aids, saliva aspiration, and instrument integration, and they have become an indispensable technical support for modern root canal treatment. Due to the highly complex structure of the pulp chamber and root canals, which often contain anatomical variations such as curvature, narrowing, or calcification, they are difficult to clearly identify with the naked eye or conventional oral mirrors alone. Therefore, various auxiliary devices have emerged to improve the visibility of the surgical area.

[0003] In existing technologies, such as the C4+ dental treatment unit with treatment handle proposed by Sirona, it is mainly used to provide stable water, air, and light output and basic operation support. It integrates high-brightness LED lighting, ergonomic grip design, highly coordinated control with the treatment unit, and reliable durability, which can meet the clinical needs of daily tooth preparation, restoration and basic endodontic treatment.

[0004] While the aforementioned products perform stably in basic diagnostic and treatment applications, their fixed illumination angle and the direction of the light source may depend on the overall orientation of the instrument, making it impossible to adjust the beam according to the complex internal anatomical structure or operating angle, which may easily create blind spots in the illumination. At the same time, their saliva cleaning port adopts a fixed aperture design, which may result in insufficient or excessive suction for cleaning different tooth surfaces, causing patient discomfort. Therefore, it is necessary to propose an auxiliary device for the treatment of oral and dental pulp diseases that is flexible and precise in operation. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides an auxiliary device for the treatment of oral and dental pulp diseases. When the doctor rotates the handle linkage mechanism, the light angle automatically adapts to the current treatment area, the saliva suction port adjusts to the corresponding size simultaneously, and the suction mechanism is activated to assist in clearing oral fluids. This allows the doctor to remain focused on the surgical procedure. Through the coordinated linkage of lighting and saliva suction functions, the blind spot in the treatment field of vision is reduced, and the accuracy of the operation is improved.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: an auxiliary device for the treatment of oral cavity and pulp diseases, comprising a handle, a sleeve fixedly connected to the handle, and a lighting mechanism for providing illumination and a saliva suction mechanism for suctioning saliva from the oral cavity at the end of the sleeve away from the handle, the saliva suction mechanism being connected to a suction mechanism for assisting in the suction of liquid; the handle is also provided with a linkage mechanism, which drives the lighting mechanism to change the light angle and drives the saliva suction mechanism to change the diameter of the suction port;

[0007] The linkage mechanism is also used to drive the suction mechanism to operate synchronously, in order to assist in suctioning saliva.

[0008] The technical principles of the above solution are as follows:

[0009] Through a linkage mechanism integrated within the handle, the lighting and suction functions are coordinated and adjusted. When the operator rotates the linkage mechanism, it synchronously drives the lighting mechanism to change the light emission angle to adapt to the visual requirements of different tooth positions. Simultaneously, the linkage mechanism drives the moving parts in the suction mechanism to change the suction orifice diameter and trigger the suction mechanism to start, assisting in suction. The integrated mechanical linkage design facilitates single-handed operation by the dentist, improving the clarity of the surgical field while efficiently managing oral fluids, thus enhancing the precision and smoothness of endodontic treatment.

[0010] The above approach has the following beneficial effects:

[0011] 1. This solution integrates lighting adjustment, suction nozzle adaptation, and suction activation into a single, multi-functional unit through a streamlined mechanical design. In traditional treatments, doctors must separately operate the lighting equipment, change the suction nozzle, or manually trigger suction, often requiring frequent tool switching and distracting attention from the treatment process. In this device, when the doctor rotates the handle's linkage mechanism, the light angle automatically adapts to the current treatment area, the suction nozzle adjusts to the corresponding size, and the suction mechanism activates to assist in clearing oral fluids. This allows the doctor to remain focused on the surgical procedure, improving the smoothness and continuity of the treatment process.

[0012] 2. This solution, through the coordinated operation of lighting and suction functions, reduces blind spots in the treatment field and improves operational precision. Traditional devices with fixed lighting angles can easily create shadows in areas such as deep root canals, and fixed-diameter suction tips are difficult to adapt to the fluid cleaning needs of different tooth positions. Residual saliva or rinsing fluid can interfere with vision, affecting diagnostic and operational accuracy. The coordinated design of this device allows the lighting angle and suction diameter to adjust synchronously with the treatment scenario; this coordinated adaptation ensures a consistently clear surgical field, enabling doctors to more accurately identify lesion details, control treatment depth, and reduce operational errors caused by limited visibility.

[0013] 3. The integrated design and collaborative functions of this solution optimize the patient experience. In traditional treatments, multiple independent instruments are often present in the oral cavity, occupying space and easily causing a foreign body sensation in patients. This device integrates multiple functions into one unit, reducing the number of instruments in the oral cavity and minimizing the space occupied. At the same time, the synchronized operation of the linkage mechanism allows the saliva suction function to respond promptly to changes in the lighting area, quickly clearing saliva, rinsing fluid, or debris, thus improving treatment safety.

[0014] Furthermore, the lighting mechanism includes a controller and several lamp beads, all of which are electrically connected to the controller; a fixing ring is fixedly connected to the outer wall of the sleeve at the end away from the handle, and several rotating rings are fitted around the fixing ring in a circumferential direction, with the lamp beads fixedly connected to the outer wall of the rotating rings; the fixing ring is provided with a drive component for driving the rotating rings to rotate.

[0015] Beneficial effects: The drive component rotates the rotating ring, allowing the LED to flexibly adjust the illumination angle to suit different tooth positions such as anterior teeth and molars; the coordinated rotation of multiple rotating rings achieves conditions for light coverage and focusing, reducing blind spots in areas such as deep root canals and proximal caries; it improves the clarity of the surgical field and assists doctors in precise operation.

[0016] Furthermore, the drive assembly includes an internal gear ring that rotatably engages within the sidewall of the fixed ring. Several pins are fixedly connected to the side of the internal gear ring away from the handle, and the inner wall of the rotating ring has helical grooves for the pins to move. The linkage mechanism is used to drive the internal gear ring to rotate.

[0017] Beneficial effects: The internal gear ring drives the pin to rotate, and the pin moves along the spiral groove on the inner wall of the rotating ring, converting the rotational motion into the circumferential deflection of the rotating ring, thereby adjusting the light emission angle of the lamp bead. This structure does not require a motor or electronic control, and the lamp bead angle can be adjusted by relying solely on pure mechanical linkage. The operation is intuitive, the response is rapid, and the stability is high.

[0018] Furthermore, the linkage mechanism includes a knob rotatably connected to the outer wall of the handle, a transmission rod coaxially fixedly connected to the knob, and the transmission rod rotatably engaging with the side wall of the sleeve; a gear is coaxially fixedly connected to the end of the transmission rod away from the knob, and the gear meshes with the internal gear ring.

[0019] Beneficial effects: Through the design of the knob on the outer wall of the handle, the coaxial transmission rod and the gear internal ring meshing, the coaxial transmission rod stably transmits power when the knob is turned, and adjusts the lighting angle synchronously, improving the smoothness of operation, helping doctors to focus on treatment steps, and enhancing the continuity of dental pulp treatment.

[0020] Furthermore, the saliva suction mechanism includes a fixed plate fixedly connected to the end of the sleeve away from the handle. A turntable is rotatably fitted on the inner wall of the fixed plate. Several inclined grooves are opened along the circumference of the side of the fixed plate away from the turntable. Movable rods are slidably fitted on the inner walls of the inclined grooves. Sliding plates are fixedly connected to the movable rods. Limiting blocks are fixedly connected to the side of the sliding plates away from the movable rods. Polygonal grooves are opened on the side of the turntable near the sliding plates. The limiting blocks are slidably fitted with the polygonal grooves. A transmission component for driving the turntable to rotate is provided on the turntable.

[0021] Beneficial effects: Through the sliding cooperation between the polygonal groove of the turntable and the limiting block, the linkage rod moves along the inclined groove, realizing flexible adjustment of the suction diameter to adapt to the liquid cleaning needs of different tooth positions; the transmission is precise and the response is rapid. With the synergistic effect of the linkage mechanism, it can efficiently remove saliva and rinsing fluid, continuously maintain a clear surgical field, and improve the smoothness and accuracy of endodontic treatment.

[0022] Furthermore, the transmission assembly includes an arc-shaped rack fixedly connected to the side of the turntable away from the sliding plate, and the arc-shaped rack meshes with the gear.

[0023] Beneficial effects: The mechanical linkage between the lighting angle adjustment and the suction nozzle diameter adjustment is achieved through the meshing design of the arc rack and gear; the coordinated action of the two can be driven synchronously by turning the handle knob, which effectively maintains a clear surgical field, simplifies the operation process, and improves the continuity and accuracy of treatment.

[0024] Furthermore, the suction mechanism includes a transmission cylinder fixedly connected to the inner wall of the handle, a transmission plate slidably fitted on the inner wall of the transmission cylinder, and an input tube and an output tube connected to the side of the transmission cylinder away from the knob; a one-way valve is provided at the connection point between the input tube and the output tube and the transmission cylinder; the end of the input tube away from the transmission cylinder is connected to the sleeve, and the end of the output tube away from the transmission cylinder is connected to the storage cavity, which is detachably connected to the outer wall of the handle; a linkage mechanism is used to drive the transmission plate to reciprocate.

[0025] Beneficial effects: The reciprocating motion of the transmission plate, combined with the one-way valve design, enables the auxiliary suction of saliva and rinsing fluid; the detachable storage cavity facilitates quick cleaning and replacement, making maintenance convenient; and the mechanical linkage with the linkage mechanism simplifies the operation process and improves the hygiene and safety of endodontic treatment.

[0026] Furthermore, the linkage mechanism also includes a threaded groove on the outer wall of the transmission rod, a nut seat is threadedly fitted on the outer wall of the threaded groove, and the nut seat is fixedly connected to the transmission plate; the outer wall of the transmission plate is also symmetrically fixedly connected with a locking block, and the inner wall of the transmission cylinder has a sliding groove for the locking block to slide.

[0027] Beneficial effects: Through the threaded engagement of the transmission rod thread groove and the nut seat, combined with the guide and limit of the locking block slide groove, the transmission plate achieves stable reciprocating motion, drives the suction mechanism to efficiently extract liquid, the mechanical transmission eliminates the risk of electronic component failure, is easy to maintain, and improves the efficiency of endodontic treatment.

[0028] Furthermore, a focusing lens is fixedly connected to the outer wall of each LED bead.

[0029] Beneficial effects: The focusing lens design concentrates the light from the LED into a focused beam, enhancing the brightness of the center of the surgical field, reducing light interference, and allowing doctors to clearly observe the tiny structures of the tooth and the details of the lesion; it is adaptable to different tooth position treatment scenarios, has strong durability, and improves treatment accuracy and efficiency.

[0030] Furthermore, an anti-slip sleeve is fixedly connected to the outer wall of the knob, and the anti-slip sleeve has anti-slip texture.

[0031] Beneficial effects: The anti-slip sleeve and anti-slip texture design of the knob improves grip friction and avoids slippage that could lead to inaccurate operation or operational errors; the anti-slip texture enhances tactile feedback and makes one-handed operation more stable.

[0040] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0041] The following detailed description illustrates the specific implementation method:

[0042] The basic implementation examples are as follows: Figures 1-7As shown: An auxiliary device for the treatment of oral cavity and pulp diseases includes a handle 1, a sleeve 2 fixedly bonded to the handle 1, and a lighting mechanism for providing illumination and a saliva suction mechanism for suctioning saliva in the oral cavity at the end of the sleeve 2 away from the handle 1. The saliva suction mechanism is connected to a suction mechanism for assisting in the suction of liquid. The handle 1 also has a linkage mechanism inside, which drives the lighting mechanism to change the light angle and drives the saliva suction mechanism to change the diameter of the suction port.

[0043] The linkage mechanism is also used to drive the suction mechanism to operate synchronously, in order to assist in suctioning saliva.

[0044] Combination Figure 3 As shown, the lighting mechanism includes a controller and several lamp beads 3, all of which are electrically connected to the controller; a fixing ring 4 is fixedly connected to the outer wall of the sleeve 2 away from the handle 1 by screws, and several rotating rings 5 ​​are fitted around the fixing ring 4 in a circumferential direction, with the lamp beads 3 all fixedly connected to the outer wall of the rotating rings 5 ​​by screws; the fixing ring 4 is provided with a drive component for driving the rotating rings 5 ​​to rotate.

[0045] The drive assembly includes an internal gear ring 6 that is rotatably fitted within the side wall of the fixed ring 4. Several pins 7 are integrally formed on the side of the internal gear ring 6 away from the handle 1. The inner wall of the rotating ring 5 is provided with spiral grooves for the pins 7 to move. The linkage mechanism is used to drive the internal gear ring 6 to rotate.

[0046] The linkage mechanism includes a knob 8 rotatably connected to the outer wall of the handle 1. A transmission rod 9 is coaxially fixed to the knob 8, and the transmission rod 9 is rotatably engaged with the side wall of the sleeve 2. A gear 10 is coaxially fixed to the end of the transmission rod 9 away from the knob 8, and the gear 10 meshes with the internal gear ring 6. In this embodiment, the knob 8 rotates in a reciprocating forward and reverse rotation mode.

[0047] Specifically, when the operator rotates knob 8, the transmission rod 9 rotates accordingly, driving the gear 10 at its end to rotate. Gear 10 meshes with the internal gear ring 6, driving the internal gear ring 6 to rotate within the fixed ring 4. Each pin 7 on the internal gear ring 6 moves accordingly and slides within the spiral groove on the inner wall of its corresponding rotating ring 5. Due to the trajectory constraint of the spiral groove, the pin 7, while sliding, pushes each rotating ring 5 to rotate synchronously around the axis of the fixed ring 4. Ultimately, the LED beads 3 fixed to the outer wall of the rotating ring 5 synchronously change their orientation, thereby achieving centralized adjustment of the lighting angle and range. For example, when treating deep teeth, the light from each LED bead 3 is focused and directed, while for wide areas, the light angle is widened to increase the coverage area; improving the ease of operation and treatment efficiency of endodontic treatment.

[0048] The saliva suction mechanism includes a fixed plate 11 that is fixedly bonded to the end of the sleeve 2 away from the handle 1. A turntable 12 is rotatably fitted on the inner wall of the fixed plate 11. Several inclined grooves (such as...) are formed along the circumference of the side of the fixed plate 11 away from the turntable 12. Figure 4As shown); the inner wall of the inclined groove is slidably fitted with movable rods 13, and each movable rod 13 is integrally formed with a sliding plate 14 (as shown). Figure 5 As shown); the side of the sliding plate 14 away from the movable rod 13 is integrally formed with a limiting block 15, and the side of the turntable 12 near the sliding plate 14 has a polygonal groove, and the limiting block 15 slides in cooperation with the polygonal groove; the turntable 12 is provided with a transmission component for driving the turntable 12 to rotate.

[0049] The transmission assembly includes an arc-shaped rack 16 (e.g., screw-fixed to the side of the turntable 12 away from the sliding plate 14) Figure 6 As shown in the figure, the arc-shaped rack 16 meshes with the gear 10.

[0050] Specifically, when gear 10 rotates with transmission rod 9, the arc-shaped rack 16 meshing with it drives turntable 12 to rotate within fixed disk 11; the polygonal groove on turntable 12 rotates accordingly, and the groove wall slides relative to each limiting block 15; since the limiting block 15 is fixed on sliding plate 14, and sliding plate 14 is constrained in the inclined groove of fixed disk 11 by movable rod 13, the pushing force of polygonal groove on limiting block 15 is decomposed into movement along the direction of inclined groove; this causes all sliding plates 14 to synchronously generate radial contraction or expansion displacement under the guidance of inclined groove; finally, through this linkage to change the suction hole diameter formed by it, adaptive change in linkage with lighting adjustment is achieved.

[0051] The suction mechanism includes a transmission cylinder 17 fixedly connected to the inner wall of the handle 1 by screws. A transmission plate 18 is slidably fitted on the inner wall of the transmission cylinder 17. An input pipe and an output pipe are connected to the side of the transmission cylinder 17 away from the knob 8. A one-way valve is provided at the connection between the input pipe and the output pipe and the transmission cylinder 17. In this embodiment, the one-way valve is used to allow the fluid to flow through the input pipe and then out through the output pipe. The end of the input pipe away from the transmission cylinder 17 is connected to the sleeve 2, and the end of the output pipe away from the transmission cylinder 17 is connected to a storage cavity. The storage cavity is detachably snapped onto the outer wall of the handle 1. A linkage mechanism is used to drive the transmission plate 18 to reciprocate.

[0052] The linkage mechanism also includes a threaded groove on the outer wall of the transmission rod 9, with a nut seat 19 threadedly fitted onto the outer wall of the groove. The nut seat 19 is fixedly bonded to the transmission plate 18. A locking block is also integrally formed symmetrically on the outer wall of the transmission plate 18, and a sliding groove is formed on the inner wall of the transmission cylinder 17 for the locking block to slide. In this embodiment, the locking block is used to provide guidance and limitation for the transmission plate 18, ensuring that the transmission plate 18 maintains a linear motion trajectory within the transmission cylinder 17. In some preferred embodiments, an independent negative pressure device is integrated on the sleeve 2 for independent saliva suction operation.

[0053] Specifically, when the transmission rod 9 rotates, the threaded groove on its outer wall engages with the threaded groove of the nut seat 19, converting the rotational motion into the axial linear movement of the nut seat 19. The nut seat 19 drives the transmission plate 18 to slide inside the transmission cylinder 17, while the locking blocks on both sides of the transmission plate 18 move along the sliding groove on the inner wall of the transmission cylinder 17 to maintain the direction of movement. When the transmission plate 18 moves away from the input pipe, a negative pressure is formed inside the transmission cylinder 17, the one-way valve of the input pipe opens and the one-way valve of the output pipe closes, and the liquid is drawn into the transmission cylinder 17 from the sleeve 2 through the input pipe. When the transmission rod 9 rotates in the opposite direction, the transmission plate 18 moves to the other side, a positive pressure is formed inside the transmission cylinder 17, the one-way valve of the input pipe closes and the one-way valve of the output pipe opens, and the liquid is forced out of the transmission cylinder 17 and discharged into the storage chamber through the output pipe.

[0054] This embodiment achieves multi-mechanism linkage through a single control point, knob 8. Rotating knob 8 synchronously drives the rotating ring 5 to adjust the angle of the lamp bead 3 to fit the surgical field; simultaneously, the rotating plate 14 is moved by the turntable 12 to change the suction orifice diameter to fit the tooth position; and the suction mechanism simultaneously completes liquid suction and storage. This linkage operation reduces clinical interference, maintains a clear and stable surgical field, and allows for the disassembly and cleaning of the storage cavity, improving the ease of operation and treatment efficiency of endodontic treatment and adapting to various clinical scenarios.

[0055] In another embodiment, a focusing lens is fixedly bonded to the outer wall of each of the lamp beads 3.

[0056] The specific implementation process is as follows:

[0057] The focusing lens design concentrates the light from the three LED beads into a focused beam, enhancing the brightness of the center of the surgical field, reducing light interference, and allowing doctors to clearly observe the tiny structures of the tooth and the details of the lesion; it is adaptable to different tooth position treatment scenarios, has strong durability, and improves treatment accuracy and efficiency.

[0058] In another embodiment, as shown in the appendix Figure 1 As shown, an anti-slip sleeve is also fixedly bonded to the outer wall of the knob 8, and anti-slip texture is provided on the anti-slip sleeve.

[0059] The specific implementation process is as follows:

[0060] The knob features an anti-slip sleeve and textured surface, enhancing grip friction and preventing slippage that could lead to inaccurate positioning or operational errors. The anti-slip texture also improves tactile feedback, making one-handed operation more stable.

[0061] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
