Description

Technical Field

[0001] This invention relates to the field of root canal solution delivery control technology, and in particular to a control method, device and system for solution delivery based on multiple channels. Background Technology

[0002] Root canal treatment is a core surgical procedure in dentistry for treating pulp necrosis and root infection. Its core steps include removing decayed dentin, extracting necrotic pulp, rinsing and disinfecting with a solution, and filling the root canal. Among these steps, the effectiveness of the solution rinsing / disinfection directly determines the success rate and accuracy of the root canal treatment, and precise solution delivery is key to the effectiveness of root canal rinsing / disinfection.

[0003] Currently, root canal treatments commonly use traditional syringes for manual injection of solutions such as irrigating fluid, disinfectant, and lubricant. Furthermore, when switching between different solutions during treatment, it often involves frequently changing syringes, inserting and removing needles, and switching solution bottles manually. This process is cumbersome, time-consuming, and prone to cross-contamination, resulting in low root canal treatment efficiency and safety hazards. Additionally, the solution delivery lines often use a single valve for control, which can lead to leaks, solution residue, and other problems. Moreover, it lacks the flexibility and convergence control of multiple channels, resulting in limited functionality.

[0004] Therefore, it is of great importance to propose a new root canal solution delivery control method that can simultaneously adapt to multiple solutions and achieve flexible switching and control of multiple input channels, thereby improving the efficiency, safety and accuracy of root canal treatment.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product, or end that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or ends.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] This invention discloses a control method, device, and system for solution delivery based on multiple channels. By opening the input channel corresponding to the desired solution while keeping other input channels closed, the corresponding solution is input into the main delivery pipeline from the open input channel. Under the control of the control unit, the solution is precisely delivered to the root canal via the output channel. This improves the accuracy and efficiency of solution delivery control for root canal treatments (such as irrigation and disinfection), reduces the risk of damage to the root canal wall due to excessive solution flow, and reduces the risk of insufficient treatment due to insufficient flow. Furthermore, by setting multiple input channels, it can simultaneously accommodate various solutions. Each input channel has its own independent control valve, eliminating the need for manual replacement of solution containers and controls. Through the coordinated control of various control valves, the flow of solution can be achieved through any channel, enabling flexible and orderly switching and control of multiple input channels. This reduces cross-contamination of solutions, ensures solution purity, and thus improves the efficiency, safety, and accuracy of root canal treatment. Detailed descriptions follow.

[0029] To better understand the control method, apparatus, and system for solution delivery based on multi-channels described in this invention, a schematic diagram of its system architecture is first described. Optionally, the schematic diagram of this system architecture can be as follows: Figure 1 As shown in the diagram, the components corresponding to this system architecture include at least two paths (such as...). Figure 1 The three independent input channels and the control valves for each input channel (such as...) Figure 1 The system includes: a solenoid valve or pinch valve and its servo motor; a main delivery pipeline; control components for controlling solution delivery; and output channels. Each input channel has a control valve to control the flow of solution within that channel, and each input channel is connected to a corresponding container containing the solution (e.g., a solenoid valve or pinch valve and its servo motor); a main delivery pipeline; control components for controlling solution delivery; and output channels. Figure 1 Bottles 1, 2, and 3 contain sodium hypochlorite solution (NAOCl), EDTA solution, and distilled water (H₂O), respectively. The control components include an input collection component (such as...). Figure 1 The four-way valve in the middle) and the power control components for providing power for solution delivery (such as...) Figure 1The peristaltic pump and the motor that powers the peristaltic pump are included. Each input channel is connected to one end of the input converging component via a corresponding control valve, and each input channel is independent at the end corresponding to the input converging component. The solution corresponding to each input channel is sequentially delivered to the main delivery pipeline via its corresponding control valve and input converging component. Furthermore, the number of output channels is greater than or equal to one (e.g., ...). Figure 1 The middle channel has two paths), and the control valve for the output channel (such as...) Figure 1 The solenoid valve in the middle can be set at the output end of the output converging component) and the output converging component (such as... Figure 1 The system uses a three-way valve (or similar three-way valve). Each output channel is connected to one end of the output converging component via a corresponding control valve. Each output channel is independent at its corresponding end on the output converging component. The control valve for each output channel controls the flow of solution within that channel. The end of each output channel connects to a root canal treatment head, such as a root canal irrigation head or a root canal disinfection head. The solution for each output channel is sequentially delivered from the outlet of the output channel to the root canal via the output converging component and the control valve of that output channel. All tubing and channels are sterile. Furthermore, as the number of input channels increases, the number or number of ports on the corresponding input converging component will also increase, such as changing a three-way valve to a four-way valve or a four-way valve to two three-way valves. Additionally, as the number of output channels increases, the output end of the power control component can be connected to a multi-way valve, such as a four-way valve or a three-way valve, before connecting to the output converging component. It should be noted that... Figure 1 The system architecture diagram shown is for illustrative purposes only and does not represent that the system architecture of this invention is limited to this specific architecture. Figure 1 As shown, other system architectures that can achieve the same function are also within the scope of protection of this invention.

[0030] Example 1 Please see Figure 2 , Figure 2 This is a schematic flowchart of a multi-channel solution delivery control method disclosed in an embodiment of the present invention. Figure 2 The described method can be applied to root canal treatment scenarios requiring solution delivery, such as root canal irrigation and disinfection. Figure 2 As shown, the method may include the following operations: 101. During root canal treatment, identify the identifier of the target solution required for the current root canal site and determine the target input channel that matches the identifier of the target solution from all input channels.

[0031] In this embodiment of the invention, the target solution includes, but is not limited to, one of the solutions used in root canal treatment, such as sodium hypochlorite solution, EDTA solution, and cleaning solution. The target solution is identified by, but is not limited to, a unique identifier such as a number or name. The type of control valve for each input channel matches the type of solution delivered by that input channel. The control valve type for each input channel includes corrosion-resistant types (such as pinch valves, diaphragm valves, and knife gate valves) or non-corrosion-resistant types (such as solenoid valves, electric ball valves, electric butterfly valves, and pneumatic valves). This targeted matching of control valves to solution types—for example, using a pinch valve specifically for the corrosive nature of sodium hypochlorite solution—effectively reduces damage to valves from corrosive solutions, extends equipment lifespan, and further reduces leakage risk. The input lines for EDTA solution and cleaning solution each use solenoid valves for rapid on / off control.

[0032] It should be noted that the solution in this application can be understood as a mixture of solute and solvent, or as any flowing liquid substance, depending on the needs of the root canal site.

[0033] In this embodiment of the invention, when solution delivery needs to be initiated, there are multiple initiation methods. Specifically, the solution delivery operation is initiated when a user-triggered initiation operation is detected on the display; or, the solution delivery operation is initiated when an initiation command is received from the worker's mobile terminal via wireless communication (such as Bluetooth); or, the solution delivery operation is initiated via wireless communication (such as Bluetooth) when the foot pedal of the root canal treatment device is detected to be pressed. These multiple initiation methods adapt to different operational scenarios, improving the ease and flexibility of initiating solution delivery, thereby enhancing the control efficiency of solution delivery.

[0034] 102. The control valve of the target input channel is opened to allow the target solution to flow from the target input channel to the main delivery pipeline; the control valves of other input channels are closed.

[0035] In this embodiment of the invention, optionally, the control component includes an input converging component and a power control component for providing power for solution delivery; each input channel is connected to one end of the input converging component via a corresponding control valve; the solution corresponding to each input channel is sequentially delivered to the main delivery pipeline via its corresponding control valve and the input converging component.

[0036] 103. When the target solution is detected flowing into the main delivery line, the control unit is controlled based on the pre-determined delivery control parameters that match the target solution to deliver the target solution from the main delivery line to the root canal via the output channel.

[0037] In this embodiment of the invention, the delivery control parameters matched with the target solution include flow control parameters and / or time control parameters, which are stored, such as in the microcontroller's flash memory. It should be noted that the flow control parameters can be a fixed value or a range, such as 3 ml / min-50 ml / min, with the flow error controlled within a preset range, such as ±1.0 ml / min, to meet the requirements for precise rinsing and disinfection in actual root canal treatment or laboratory root canal treatment scenarios. Specifically, based on the pre-determined delivery control parameters matched with the target solution, the control unit delivers the target solution from the main delivery pipeline through the output channel to the root canal. Specifically: based on the flow control parameters, the corresponding voltage control parameters are determined, and the power control unit operates based on the voltage control parameters, driving its corresponding motor to rotate at the corresponding speed (wherein, the driving speed should be determined according to the actual situation of the motor type; for example, for a motor controlled by duty cycle PWM, the higher the voltage, the faster the speed and the greater the flow rate), thereby performing corresponding flow control based on the corresponding time control parameters. Taking a peristaltic pump as an example, its internal components consist of rollers, with a water pipe resting on the rollers. When it rotates, a timer begins. The rollers squeeze the water pipe, creating pressure that forces air out of the pipe. This air pressure then propels the liquid flow. The flow rate of the solution is directly proportional to the speed of the peristaltic pump. When a flow rate of 50 ml / min is required, the program controls the peristaltic pump to increase its speed. When a flow rate of 5 ml / min is required, the program reduces the speed of the peristaltic pump to achieve the desired flow control. When the timer reaches the set time, it stops, and the peristaltic pump stops working, or it begins delivering the next solution and the timer restarts.

[0038] In this embodiment of the invention, it should be noted that the aforementioned steps 101-103 can be understood as only one target solution is transported at a time, or as multiple target solutions are transported simultaneously. In this case, the control valve of each channel is opened, and the motor of the power control component is controlled to rotate, so as to achieve different flow rate control.

[0039] It is evident that implementation Figure 2The described method, by controlling the opening of the input channel corresponding to the desired solution while keeping other input channels closed, allows the corresponding solution to be input from the open input channel into the main delivery pipeline. Under the control of the control unit, the solution is precisely delivered to the root canal via the output channel. This improves the accuracy and efficiency of solution delivery control for root canal treatments (such as irrigation and disinfection), reduces the risk of damage to the root canal wall due to excessive solution flow, and reduces the risk of insufficient treatment due to insufficient flow. Furthermore, by setting up multiple input channels, it can simultaneously accommodate various solutions. Each input channel has its own independent control valve, eliminating the need for manual replacement of solution containers and controls. Through the coordinated control of various control valves, the flow of solution can be achieved through any channel, enabling flexible and orderly switching and control of multiple input channels. This reduces cross-contamination of solutions, ensures solution purity, and thus improves the efficiency, safety, and accuracy of root canal treatment.

[0040] In this embodiment of the invention, optionally, determining the target input channel that matches the identifier of the target solution from all input channels includes: Based on the identifier of the target solution, determine the target input channel that matches the identifier of the target solution from all input channels; each input channel has a corresponding solution identifier; or, The system detects the user's touch operation on the display corresponding to the target solution's channel selection. Based on the touch operation selected by the user on the target solution's channel selection, the system filters out the input channels that match the touch operation selected on that channel from all input channels and selects the target input channel that matches the identifier of the target solution.

[0041] In this embodiment of the invention, a pre-established association relationship is established between each input channel and its corresponding solution identifier. Based on the association relationship, the target input channel that matches the identifier of the target solution is determined from all input channels.

[0042] In this embodiment of the invention, each solution has a corresponding channel identifier (such as number, color, shape, etc.) on the display for the user to touch. The user's selection touch operation on the channel identifier is detected, and the input channel corresponding to the selection touch operation is selected from all input channels according to the corresponding selection touch operation.

[0043] It should be noted that the target input channel selection methods of the two are not contradictory and can coexist.

[0044] As can be seen, implementing the embodiments of the present invention can also automatically match the corresponding input channel based on the identifier of the solution currently required in the root canal, or automatically select the corresponding input channel by detecting the user's channel selection touch operation triggered on the display. This improves the efficiency and accuracy of determining the required input channel, reduces solution mixing and cross-contamination caused by incorrect input channel selection, and thus helps improve the accuracy, efficiency, and safety of subsequent solution delivery control. Furthermore, automatically matching channels based on solution identifiers enables intelligent and automated determination of input channels, reducing manual operation steps and improving solution switching efficiency. Additionally, determining the corresponding input channel by detecting the user's touch operation on the display caters to the user's personalized operating habits and meets the flexible needs of complex root canal treatment scenarios. Both methods can accurately match the target solution with the corresponding input channel, avoiding solution mixing and cross-contamination caused by incorrect channel selection, ensuring the accuracy and safety of solution delivery, while simplifying the operation process and improving the human-computer interaction experience and clinical operation convenience of the device.

[0045] In an optional embodiment, the method may further include the following steps: During the process of controlling the delivery of the target solution, the real-time delivery flow rate of the corresponding output channel is collected; Calculate the difference between the real-time delivery flow rate corresponding to the target solution and the reference delivery flow rate corresponding to the predetermined flow control parameters of the target solution; Determine whether the real-time delivery flow difference is greater than or equal to the preset flow difference. When it is determined that the flow difference is greater than or equal to the preset flow difference, obtain the motor speed of the power control component. Based on the real-time flow difference, the speed of the motor in the power control unit is adjusted until the real-time flow difference of the target solution is less than the preset flow difference.

[0046] In this optional embodiment, a corresponding flow collector is provided on the output channel to collect the real-time transmission flow of the output channel.

[0047] In this optional embodiment, when it is determined that the difference is less than a preset flow rate, the process ends or the operation of collecting the real-time transmission flow rate of the corresponding output channel is continued.

[0048] As can be seen, implementing this optional embodiment, by collecting the real-time delivery flow rate of the output channel and comparing it with the reference delivery flow rate, and dynamically correcting the rotation speed of the power control component based on the flow rate difference when the difference is large, forms a closed-loop real-time flow control, ensuring that the delivery flow rate is stable within an acceptable range, further improving the accuracy and reliability of solution delivery in root canal treatment; and by directly correcting the motor speed of the power control component, it is beneficial to improve the response efficiency and accuracy of flow rate correction, further reducing the impact of excessive flow rate on root canal damage or insufficient flow rate on treatment, further improving the safety and accuracy of root canal treatment.

[0049] In this optional embodiment, the method may further include the following steps: Based on the identifier of the target solution, obtain the viscosity coefficient corresponding to the target solution; Obtain the attribute parameters of the target input channel, the attribute parameters of the total delivery pipeline, and the attribute parameters of the corresponding output channel. Each attribute parameter includes length and / or curvature (such as the number of bends and the degree of curvature at each bend) and / or cross-sectional area of ​​the passage. For any target object, based on the viscosity coefficient of the target solution and any attribute parameter of the target object, a flow correction coefficient corresponding to the attribute parameter is generated, and based on the flow correction coefficients corresponding to all attribute parameters of the target solution, a flow correction coefficient for the target object is generated. The target object includes one of the target input channel, the main delivery pipeline, and the corresponding output channel. The flow correction coefficient for the target solution is generated based on the flow correction coefficient for each target object and the pre-determined correction weight for that target object (e.g., 0.2 for the input channel, 0.3 for the total delivery pipeline, and 0.5 for the output channel). The speed of the motor in the aforementioned power control component is further corrected based on the flow correction factor of the target solution.

[0050] In this optional embodiment, different solutions have different viscosity coefficients. The higher the viscosity coefficient, the higher the viscosity of the solution against the inner wall of the passage.

[0051] In this optional embodiment, the longer the pipeline, the greater the solution resistance, the greater the flow loss, and the greater the flow correction factor; the more bends / the larger the angle, the greater the resistance, the greater the flow loss, and the greater the flow correction factor; the smaller the cross-sectional area, the greater the flow loss, and the greater the flow correction factor.

[0052] As can be seen, implementing this optional embodiment analyzes the viscosity coefficient of the current delivery solution with each attribute parameter of the input channel / total delivery pipeline / output channel to obtain the flow correction coefficient corresponding to each object. Furthermore, based on the flow correction coefficient and corresponding weight of each object, the final flow correction coefficient is generated, which improves the accuracy of the flow correction coefficient generation. This allows for secondary correction of the motor speed of the power control component, further improving the accuracy of motor speed correction. This enables solutions of different viscosities to stably reach the reference flow range in complex pipelines, reducing flow deviations caused by solution characteristics and pipeline structure. This further improves the stability and accuracy of solution delivery in root canal treatment, and further enhances the safety and accuracy of root canal treatment.

[0053] In another optional embodiment, the number of output channels is greater than or equal to 2; the solution delivery system also includes a control valve for each output channel and an output converging component, each output channel is connected to one end of the output converging component via a corresponding control valve, and the control valve for each output channel is used to control the flow of solution in the output channel; the solution corresponding to each output channel is sequentially delivered to the root canal via the output converging component and the control valve of the output channel. The method may also include the following steps: Based on the identifier of the target solution, filter out the output channels that match the identifier of the target solution from all output channels; The control valve of the output channel corresponding to the target solution is opened so that the target solution is delivered from that output channel to the root canal; the control valves of other output channels are closed.

[0054] In this optional embodiment, similarly, the type of control valve for each output channel is matched to the type of solution delivered by that output channel. The type of control valve for each output channel includes corrosion-resistant types (such as pinch valves, diaphragm valves, knife gate valves, etc.) or non-corrosion-resistant types (such as solenoid valves, electric ball valves, electric butterfly valves, pneumatic control valves, etc.).

[0055] It should be noted that when there are more output channels, the number of output channels corresponding to the target solution can be 1, 2, or other. In this case, the control valves of the corresponding output channels are all in the open state, while the control valves of other output channels are in the closed state.

[0056] As can be seen, this optional embodiment, by setting up two or more output channels and independently controlling them with corresponding control valves, combined with an output converging component, achieves flexible switching and control of the output channels. This enables precise directional delivery of the solution after convergence, meeting the needs of different root canal sites or treatment stages. Furthermore, by precisely matching the corresponding output channel with solution identifiers, opening only the control valve of that output channel and closing the control valves of the others, it effectively reduces solution mixing and dosage loss caused by simultaneous output from multiple channels, lowers the risk of cross-contamination during multi-channel switching, and ensures the accuracy, efficiency, and safety of solution delivery in root canal treatment, thereby further improving the accuracy, efficiency, and safety of root canal treatment. Moreover, by rationally configuring the control valves of the input channels, the input converging component, the output converging component, the control valves of the output channels, and the power control components, and through the coordinated control of these components to maintain tubing flow, it reduces the possibility of tubing leakage and solution residue, further reducing the risk of solution cross-contamination, and further improving the safety and accuracy of root canal solution delivery, thus contributing to further improving the safety and accuracy of root canal treatment.

[0057] In yet another optional embodiment, the method may further include the following steps: The system detects parameter setting operations triggered by the target user on the display that match the target object, which includes the target solution or the target input channel; it analyzes the parameter setting operations corresponding to the target object to obtain the delivery control parameters that match the target solution. or, Based on the identification of the target solution, determine the valve size that the control valve of the target input channel needs to open; based on the identification of the target solution and the valve size corresponding to the target input channel, determine the delivery control parameters that match the target solution.

[0058] In this optional embodiment, the display is provided with parameter setting options for each solution or each input channel, such as flow rate and time. By detecting and analyzing the parameter setting operations triggered by the user's parameter setting options on the display, the corresponding delivery control parameters can be obtained.

[0059] In this optional embodiment, each solution and the valve size of the corresponding input channel control valve have corresponding delivery control parameters, and the three are pre-associated. Based on the corresponding association, the delivery control parameters matching the solution can be determined.

[0060] It should be noted that the methods for determining the control parameters for both are not contradictory and can coexist.

[0061] As can be seen, implementing this optional embodiment improves the accuracy and efficiency of solution delivery control parameter determination by detecting user-triggered parameter setting operations on the display, or by automatically matching the corresponding delivery control parameters based on the solution identifier and the valve size of the corresponding input channel. This helps to improve the accuracy and efficiency of solution delivery, reduce abnormal flow and pressure caused by parameter setting errors, and further improve the accuracy and efficiency of root canal treatment. Furthermore, setting parameters via touchscreen on the display satisfies users' manual operation habits, allowing for personalized and flexible setting of delivery control parameters to meet the differentiated needs of different root canal locations and treatment stages. The automatic matching of valve size based on the solution identifier to generate corresponding delivery control parameters achieves intelligent and automated parameter analysis, reduces manual operation steps, and improves the efficiency of determining delivery control parameters.

[0062] Example 2 Please see Figure 3 , Figure 3 This is a schematic flowchart of another control method for solution delivery based on multi-channels disclosed in an embodiment of the present invention. Figure 3 The described method can be applied to root canal treatment scenarios requiring solution delivery, such as root canal irrigation and disinfection. Figure 3 As shown, the method may include the following operations: 201. During root canal treatment, identify the identifier of the target solution required for the current root canal site and determine the target input channel that matches the identifier of the target solution from all input channels.

[0063] 202. The control valve of the target input channel is opened to allow the target solution to flow from the target input channel to the main delivery pipeline; the control valves of other input channels are closed.

[0064] 203. When the target solution is detected flowing into the main delivery line, the control unit is controlled based on the pre-determined delivery control parameters that match the target solution to deliver the target solution from the main delivery line to the root canal via the output channel.

[0065] It should be noted that for other descriptions of steps 201-203, please refer to the relevant descriptions of steps 101-103 in Embodiment 1, which will not be repeated here.

[0066] 204. Once the target solution delivery is complete, another solution is identified as the target solution, and the operation described above, which involves identifying the target input channel that matches the target solution's identifier from all input channels, is repeated until the root canal is completely treated.

[0067] In this embodiment of the invention, "completion of root canal treatment" can be understood as the complete completion of the current root canal treatment, or as the current root canal treatment being interrupted midway and requiring other operations; both are within the scope of this invention. It should also be noted that "re-executing the operation of determining the corresponding target input channel" means re-executing steps 201-203.

[0068] It should also be noted that all target solutions and their corresponding delivery control parameters to be delivered in this root canal treatment can be determined together at the beginning, and the next target solution can be delivered directly after the current target solution is delivered; or the next target solution and its corresponding delivery control parameters can be determined after the current target solution is delivered, and then the solution is delivered; or the next target solution and its corresponding delivery control parameters can be determined during the delivery of the current target solution, and then the next target solution is delivered after the current target solution is delivered.

[0069] The method further includes: 205. Once the root canal treatment is completed, the control valve of any input channel is opened to allow the cleaning solution to flow from the input channel to the main delivery line.

[0070] In this embodiment of the invention, the input channels that need to be cleaned are those that have undergone solution delivery. Each input channel can be cleaned independently or in parallel.

[0071] 206. When the cleaning solution corresponding to the input channel is detected to flow to the main delivery pipeline, the control unit is controlled based on the predetermined cleaning control parameters to transport the cleaning solution corresponding to the input channel from the main delivery pipeline to the output channel corresponding to the input channel.

[0072] In this embodiment of the invention, the cleaning solution is a solution capable of cleaning, such as distilled water. The cleaning control parameters also include flow control parameters and / or time control parameters. The description of the cleaning control process can be found in the solution delivery control process, and will not be repeated here.

[0073] It is evident that implementation Figure 3The described method, by controlling the opening of the input channel corresponding to the desired solution while keeping other input channels closed, allows the corresponding solution to be input from the open input channel into the main delivery pipeline. Under the control of the control unit, the solution is precisely delivered to the root canal via the output channel. This improves the accuracy and efficiency of solution delivery control for root canal treatments (such as irrigation and disinfection), reduces the risk of damage to the root canal wall due to excessive solution flow, and reduces the risk of insufficient treatment due to insufficient flow. Furthermore, by setting up multiple input channels, it can simultaneously accommodate various solutions. Each input channel has its own independent control valve, eliminating the need for manual replacement of solution containers and controls. Through the coordinated control of various control valves, the flow of solution can be achieved through any channel, enabling flexible and orderly switching and control of multiple input channels. This reduces cross-contamination of solutions, ensures solution purity, and thus improves the efficiency, safety, and accuracy of root canal treatment. Furthermore, after the current solution delivery is completed, the system automatically and continuously switches to the next solution delivery, adapting to the solution usage requirements of each root canal treatment stage. Multiple solutions can be precisely delivered sequentially without manual intervention, improving the overall solution delivery efficiency throughout the root canal treatment process and further enhancing the accuracy and efficiency of root canal treatment. After root canal treatment is completed, the system automatically initiates a full-pipeline cleaning process, allowing the cleaning solution to flow through all input channels, the main delivery pipeline, and the corresponding output channels to thoroughly remove any residual treatment solution from the pipeline. This reduces cross-contamination or pipeline blockage caused by solution residue, ensuring pipeline cleanliness for direct solution delivery in the next cycle and extending its service life.

[0074] In an optional embodiment, the method may further include the following steps: Determine the liquid back-pull time corresponding to the target solution; When the real-time working time of the power control unit for the target solution reaches the cutoff time of the time control parameter corresponding to the target solution, a liquid recovery command is generated for the power control unit based on the liquid retrieval time corresponding to the target solution. According to the liquid recovery command from the control unit, the power control unit is controlled to rotate in the reverse direction to perform a back-pull operation on the residual solution in the target output channel; after the back-pull operation on the residual solution in the target output channel is completed, the operation of determining the target input channel that matches the target solution's identifier from all input channels is re-executed based on the identifier of the target solution.

[0075] In this optional embodiment, the liquid back-pull time corresponding to the target solution can be fixed, or it can be determined based on the properties (such as viscosity) / identification of the target solution, and / or the delivery time of the target solution, and / or the properties of the output channel (such as shape, inlet size, inner wall material, etc.). By using a fixed solution back-pull time, or by precisely determining the corresponding solution back-pull time based on the solution conditions, delivery time, and output channel properties, the accuracy of determining the solution back-pull time is improved, which is beneficial for further improving the thoroughness of residual solution back-pull.

[0076] As can be seen, this optional embodiment accurately determines the liquid aspiration time corresponding to the current solution delivery. After the current solution delivery reaches the preset time, i.e., after completion, it automatically generates the corresponding aspiration command and controls the power control component to rotate in the opposite direction to aspirate the residual solution in the output end of the output channel. This reduces the dosage deviation in the root canal caused by residual solution dripping, further ensuring the accuracy of root canal treatment, and also reduces residual mixing when switching between different solutions, reducing the risk of cross-contamination. After the solution aspiration is completed, it automatically triggers the next round of solution channel matching for solution delivery, improving the execution accuracy and reliability of seamless automated switching of multiple solution deliveries. It requires no manual intervention, simplifies the switching operation process, and improves the overall efficiency and accuracy of root canal treatment.

[0077] Example 3 Please see Figure 4 , Figure 4 This is a schematic diagram of a control device for solution delivery based on multiple channels, as disclosed in an embodiment of the present invention. Figure 4 The described device can be applied to root canal treatment scenarios requiring solution delivery, such as root canal irrigation and disinfection, and is used in a solution delivery system. The solution delivery system includes at least two independent input channels and a control valve for each input channel, a main delivery pipeline, control components for controlling solution delivery, and an output channel. The control valve for each input channel controls the on / off flow of solution within that input channel. Figure 4 As shown, the device may include: The determination module 301 is used to determine the identifier of the target solution required for the current root canal site during root canal treatment. The determination module 301 is also used to determine, from all input channels, the target input channel that matches the identifier of the target solution; Control module 302 is used to control the opening of the control valve of the target input channel so that the target solution flows from the target input channel to the main delivery pipeline; the control valves of other input channels are in the closed state. The control module 302 is also used to control the control unit to deliver the target solution from the main delivery pipeline to the root canal via the output channel when the target solution is detected to be flowing into the main delivery pipeline. This is based on the pre-determined delivery control parameters that match the target solution.

[0078] In this embodiment of the invention, the control component includes an input converging component and a power control component for providing power for solution delivery; each input channel is connected to one end of the input converging component via a corresponding control valve; the type of control valve for each input channel matches the type of solution delivered by that input channel, and the type of control valve for each input channel includes corrosion-resistant or non-corrosion-resistant types; the solution corresponding to each input channel is sequentially delivered to the main delivery pipeline via its corresponding control valve and the input converging component.

[0079] It is evident that implementation Figure 4 The described device, by opening the input channel corresponding to the desired solution while keeping other input channels closed, allows the corresponding solution to be input from the open input channel into the main delivery pipeline. Under the control of the control unit, the solution is precisely delivered to the root canal via the output channel. This improves the accuracy and efficiency of solution delivery control for root canal treatments (such as irrigation and disinfection), reduces the risk of damage to the root canal wall due to excessive solution flow, and reduces the risk of insufficient treatment due to insufficient flow. Furthermore, by setting multiple input channels, it can simultaneously accommodate various solutions. Each input channel has its own independent control valve, eliminating the need for manual replacement of solution containers and controls. Through the coordinated control of various valves, the flow of solution through any channel is achieved, enabling flexible and orderly switching and control of multiple input channels. This reduces cross-contamination of solutions, ensures solution purity, and thus improves the efficiency, safety, and accuracy of root canal treatment.

[0080] In this embodiment of the invention, optionally, the determining module 301 determines the specific method by which it determines the target input channel that matches the identifier of the target solution from all input channels, including: Based on the identifier of the target solution, determine the target input channel that matches the identifier of the target solution from all input channels; each input channel has a corresponding solution identifier; or, The system detects the user's touch operation on the display corresponding to the target solution's channel selection. Based on the touch operation selected by the user on the target solution's channel selection, the system filters out the input channels that match the touch operation selected on that channel from all input channels and selects the target input channel that matches the identifier of the target solution.

[0081] It is evident that implementation Figure 4The described device can automatically match the corresponding input channel based on the identifier of the solution currently needed in the root canal, or automatically select the corresponding input channel by detecting the user's touch operation triggered by channel selection on the display. This improves the efficiency and accuracy of determining the required input channel, reduces solution mixing and cross-contamination caused by incorrect input channel selection, and thus helps improve the accuracy, efficiency, and safety of subsequent solution delivery control. Furthermore, it automatically matches channels based on solution identifiers, achieving intelligent and automated determination of input channels, reducing manual operation steps and improving solution switching efficiency. Additionally, it determines the corresponding input channel by detecting user touch operations on the display, catering to personalized user operating habits and meeting the flexible needs of complex root canal treatment scenarios. Both methods can accurately match the target solution with the corresponding input channel, avoiding solution mixing and cross-contamination problems caused by incorrect channel selection, ensuring the accuracy and safety of solution delivery, while simplifying the operation process and improving the human-computer interaction experience and clinical ease of operation.

[0082] In an optional embodiment, the number of output channels is greater than or equal to 2; the solution delivery system also includes a control valve for each output channel and an output converging component, each output channel being connected to one end of the output converging component via a corresponding control valve, and the control valve for each output channel being used to control the flow of solution in that output channel; the solution corresponding to each output channel is sequentially delivered to the root canal via the output converging component and the control valve of that output channel. like Figure 5 As shown, the device also includes: The filtering module 303 is used to filter the output channels that match the identifier of the target solution from all output channels based on the identifier of the target solution.

[0083] The control module 302 is also used to control the opening of the control valve of the output channel corresponding to the target solution, so that the target solution is delivered from the output channel to the root canal; the control valves of other output channels are in the closed state.

[0084] It is evident that implementation Figure 5The described device, by setting up two or more output channels and independently controlling them with corresponding control valves, combined with an output converging component, achieves flexible switching and control of the output channels. This enables precise directional delivery of the solution after convergence, meeting the needs of different root canal sites or treatment stages. Furthermore, by precisely matching the corresponding output channel with a solution identifier, opening only the control valve of that output channel and closing the control valves of the others, it effectively reduces solution mixing and dosage loss caused by simultaneous output from multiple channels, lowers the risk of cross-contamination during multi-channel switching, and ensures the accuracy, efficiency, and safety of solution delivery in root canal treatment, thereby further improving the accuracy, efficiency, and safety of root canal treatment. Moreover, by rationally configuring the control valves of the input channels, the input converging component, the output converging component, the control valves of the output channels, and the power control component, and through the coordinated control of these components to maintain tubing flow, it reduces the possibility of tubing leakage and solution residue, further reducing the risk of solution cross-contamination, and further improving the safety and accuracy of root canal solution delivery, thus contributing to further improving the safety and accuracy of root canal treatment.

[0085] In another alternative embodiment, such as Figure 5 As shown, the device may also include; The detection module 304 is used to detect parameter setting operations triggered by the target user on the display that match the target object, including the target solution or the target input channel, and analyze the parameter setting operations corresponding to the target object to obtain the delivery control parameters that match the target solution. or, The determination module 301 is also used to determine the valve size that the control valve of the target input channel needs to be opened according to the identification of the target solution, and to determine the delivery control parameters that match the target solution according to the identification of the target solution and the valve size corresponding to the target input channel. The delivery control parameters matched to the target solution include flow control parameters and / or time control parameters.

[0086] It is evident that implementation Figure 5The described device improves the accuracy and efficiency of solution delivery control parameters by detecting user-triggered parameter setting operations on the display, or by automatically matching the corresponding delivery control parameters based on the solution identifier and the valve size of the corresponding input channel. This enhances the accuracy and efficiency of solution delivery, reduces flow and pressure anomalies caused by parameter setting errors, and further improves the accuracy and efficiency of root canal treatment. Furthermore, the device allows for parameter setting via touchscreen, catering to users' manual operation habits and enabling personalized and flexible setting of delivery control parameters to meet the differentiated needs of different root canal locations and treatment stages. The device also automatically matches valve sizes based on solution identifiers to generate corresponding delivery control parameters, achieving intelligent and automated parameter analysis, reducing manual operation steps, and improving the efficiency of delivery control parameter determination.

[0087] In yet another alternative embodiment, such as Figure 5 As shown, the determination module 301 is also used to determine another solution as the target solution after the target solution delivery is detected, and to re-execute the operation of determining the target input channel that matches the target solution's identifier from all input channels based on the identifier of the target solution, until the root canal is treated. The control module 302 is also used to control the control valve of any input channel to open when the root canal is detected to be finished, so that the cleaning solution flows from the input channel to the main delivery line. The control module 302 is also used to control the control unit to transport the cleaning solution corresponding to the input channel from the main delivery pipeline to the output channel corresponding to the input channel based on the predetermined cleaning control parameters when the cleaning solution corresponding to the input channel is detected to flow to the main delivery pipeline.

[0088] It is evident that implementation Figure 5 The described device automatically and continuously switches to the next solution delivery immediately after the current solution delivery is completed, adapting to the solution usage needs of each root canal treatment stage. It can accurately deliver multiple solutions sequentially without manual intervention, thereby improving the solution delivery efficiency of the entire root canal treatment process and further enhancing the accuracy and efficiency of root canal treatment. After the root canal treatment is completed, it automatically starts a full-line cleaning process with a cleaning solution, allowing the cleaning solution to flow through all input channels, the main delivery line, and the corresponding output channels to thoroughly remove residual treatment solution from the lines. This reduces cross-contamination or line blockage caused by solution residue, ensuring the cleanliness of the lines for direct solution delivery in the next step and extending their service life.

[0089] In yet another alternative embodiment, such as Figure 5 As shown, the determining module 301 is also used to determine the liquid back-pull time corresponding to the target solution; like Figure 5As shown, the device may also include; The generation module 305 is used to generate a liquid recovery command for the power control unit based on the liquid retrieval time corresponding to the target solution when the real-time working time of the power control unit for the target solution reaches the cutoff time of the time control parameter corresponding to the target solution. The control module 302 is also used to control the power control component to rotate in the reverse direction according to the liquid recovery command of the control component, and to perform a back-pull operation on the residual solution in the target output channel; when the back-pull operation of the residual solution in the target output channel is completed, the determination module 301 is triggered to re-execute the operation of determining the target input channel that matches the identifier of the target solution from all input channels according to the identifier of the target solution.

[0090] It is evident that implementation Figure 5 The described device precisely determines the liquid aspiration time corresponding to the current solution delivery. After the current solution delivery reaches the preset time, it automatically generates a corresponding aspiration command and controls the power control component to rotate in the opposite direction to aspirate the residual solution in the output end of the output channel. This reduces dosage deviation in the root canal caused by residual solution dripping, further ensuring the accuracy of root canal treatment. It also reduces residual mixing when switching between different solutions, reducing the risk of cross-contamination.
