[0053] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement them. In addition, for the sake of clarity, parts not related to the description of the exemplary embodiments are omitted in the accompanying drawings.
[0054] In the present disclosure, it should be understood that terms such as "include" or "have" are intended to indicate the presence of features, numbers, steps, behaviors, components, parts, or a combination thereof disclosed in the present specification, and are not intended to exclude the possibility that one or more other features, numbers, steps, behaviors, components, parts, or a combination thereof exist or are added.
[0055] It should also be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0056] As mentioned above, the preparation of existing radiation protection applicators relies on manual operations by technicians, including cutting tablets with scissors, applying medicine with a straw, and suturing with a soldering iron. On the one hand, pure manual operation is inefficient and difficult to meet the needs of treating a large number of patients at the same time; and the cutting size of the patch and the application of the medicine are completely dependent on the technician's experience and skills, which may result in poor dimensional accuracy and consistency of medicine distribution; on the other hand, technicians need to directly contact radioactive agents and there is a risk of radiation.
[0057] To solve the above problems, an embodiment of the present disclosure provides an automated production system for radiation protection applicators. By designing an integrated automatic integration system, the cutting, drug application, heat suturing and other processes are fully automated, the preparation process of the radiation protection applicator reduces manual operations and gets rid of the long-term reliance on the skills and experience of technicians; intelligent image recognition means are used to improve the accuracy of image recognition, thereby ensuring the accuracy of automatic cutting, so that the size of the applicator is more in line with the actual needs of the patient, improving the accuracy of treatment while improving the user experience.
[0058] Figure 1 A schematic structural diagram of an automated production system for a radiation protection applicator according to an embodiment of the present disclosure is shown.
[0059] An automated production system for the integrated preparation of radiation protection applicators. Figure 1 As shown, the automated production system mainly includes two parts: a main control center module 10 and an integrated system 20.
[0060] Among them, the main control center module 10 is electrically connected to the integrated system 20. The main control center module 10 can be one or more electronic components such as application integrated circuits (ASICs), digital signal processors (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), and central processing units (CPUs). Specifically, the main control center module 10 of the present disclosure may include a logic controller and an image processing unit. The logic controller controls the components in the automated production system to operate independently or to cooperate with each other, and the image processing unit uses a multi-layer convolutional neural network in deep learning to process the image to identify the ROI (Region of Interest) of the target area.
[0061] The integrated system 20 is arranged beside the main control center module 10 and is electrically connected to the main control center module 10 so as to be controlled by the main control center module 10 to perform the automated production of the radiation protection applicator. The integrated system 20 disclosed in the present invention is a highly integrated device, and the automated production process reduces the manual operation time and greatly improves the production efficiency. At the same time, the precision manufacturing process, such as automated cutting, precise drug supply, and precision thermal fusion integration, effectively improves the processing accuracy, yield rate, and the therapeutic effect of the prepared applicator.
[0062] like Figure 2 As shown, the integrated system 20 of the present disclosure includes a base 21, a work component 30 fixed on the base 21 and divided into a first cutting area 22, a medicine spraying area 23, a heat stitching area 24, and a second cutting area 25 along a first direction (e.g., X-axis direction). The work component 30 of the present disclosure can be understood as a functional element capable of performing at least one or more work actions, such as a multi-functional workbench, a robotic arm, a camera, a laser cutter, a glue dropper, a hot melt gun, etc.
[0063] For example, the operation assembly 30 of the present disclosure may include: a multifunctional workbench 31, an image acquisition module 32, a cutting module 33, a second mechanical arm 34, a spraying module 35, a heat sewing module 36 and other components.
[0064] A multifunctional workbench 31 is installed above the base 21 and is adapted to each functional area of the integrated system 20. Preferably, the multifunctional workbench 31 includes a first workbench 310, which is arranged in the first cutting area 22, a second workbench 311, which is arranged in the medicine sprinkling area 23, a third workbench 312, which is arranged in the heat stitching area 24, and a fourth workbench 313, which is arranged in the second cutting area 25. In order to facilitate the fixed positioning of the workpiece to be processed, at least part of the multifunctional workbench 31 of the present invention is configured with a positioning device (not shown in the figure), which includes a storage plate evenly distributed with mesh holes and a negative pressure fan connected to the storage plate, and a negative pressure is formed at the bottom of the storage plate by the negative pressure fan to adsorb and fix the workpiece to be processed. Further, the positioning device can be selectively arranged on the first workbench, the third workbench and the fourth workbench.
[0065] The image acquisition module 32 is electrically connected to the image processing unit in the main control center module 10 for communication. The image information parameters acquired by the image acquisition module 32 are fed back to the image processing unit. After being processed by the deep learning algorithm, the image information parameters of the workpiece to be measured can be identified as the ROI of the target area.
[0066] According to one embodiment of the present disclosure, the image acquisition module 32 may include a camera 320 and a first slide 321.

The first slide 321 may reciprocate along a first direction, and the camera 320 may be configured to rotate within a certain range relative to the first slide 321, so that the image acquisition module 32 can meet the image acquisition requirements of multiple positions and different angles.
[0067] The image acquisition module 32 is used to acquire the first image information of the workpiece to be processed on the multifunctional workbench 31, and transmit the acquired first image information to the image processing unit of the main control center module 10. The image processing unit uses an image processing algorithm, such as a U-Net image segmentation network, to extract information from the target area to obtain information such as the position and edge contour of the workpiece to be processed. The logic control unit in the main control center module 10 automatically plans a cutting path based on the position and edge contour information of the workpiece to be processed identified and extracted by the image processing unit, and sends the execution instruction information containing the cutting path to the cutting module 33, so that the cutting module 33 automatically executes the cutting task according to the instruction.
[0068] The cutting module 33 includes a second slide 330, a first mechanical arm 331 and a shearing unit 332 arranged at the end of the first mechanical arm 331. The first mechanical arm 331 is fixedly connected to the bottom of the second slide 330 and suspended above the multifunctional workbench 31 through the second slide 330. The second slide 330 is configured to be able to move back and forth in a straight line along the first direction, so that the cutting module 33 is suitable for free movement in the first cutting area 22 and the second cutting area 25. The present disclosure exemplarily illustrates that the cutting operation of the first cutting area and the second cutting area is realized by setting a set of cutting equipment. It should be understood by ordinary technicians in this field that according to actual production needs, the same or different cutting equipment can be set in the first cutting area and the second cutting area to perform cutting operations on the workpiece to be processed, and the present disclosure does not make any special restrictions here. Moreover, it should be understood that under the cooperative control of the main control center module, the action of the second slide of the present disclosure and the action of the first slide should not interfere with each other, and the movement of one does not affect the normal operation of the other.
[0069] Preferably, the cutting unit 332 of the present disclosure can be selected from a laser cutter, a precision mechanical cutting device, a water jet cutter or other precision cutting equipment. More preferably, the cutting unit 332 can use a precision laser cutter, which has the advantages of rapid response and high-precision processing, and can accurately cut along the ROI boundary, ensuring the maximum similarity between the cut ROI shape and the original scar shape, while ensuring that the drug cost in the ROI area is not destroyed, which helps to improve the effect of the patch treatment.
[0070] According to an embodiment of the present disclosure, the second robot arm 34 may be configured to be movably mounted above the multifunctional workbench 31 along a first direction, and used for grasping and carrying workpieces or materials to be processed. Figure 2 As shown, the second robot arm 34 is suspended above the multifunctional workbench through the third slide 340, and a gripping mechanism 341 is installed at the distal end of the second robot arm 34. Preferably, the gripping mechanism 341 can be a vacuum adsorption device. The present disclosure automatically grips and transports the workpiece to be processed between the first workbench 310, the second workbench 311, the third workbench 312 and the fourth workbench 313 through the second robot arm 34.
[0071] The medicine sprinkling module 35 disposed in the medicine sprinkling area 23 is as follows: Figure 3 As shown, the medicine sprinkling module 35 includes a third mechanical arm 350, a metering pump 351, a liquid storage tube 352, a micro-liquid injection head 353 and a positioning unit 354, and the liquid storage tube 351, the metering pump 351 and the micro-liquid injection head 353 are connected in sequence.

The end effector obtains the position signal of the positioning unit 354 in real time, and at the same time receives the medicine spraying instruction issued by the main control center module 10, and evenly applies the medicine liquid to the target medicine spraying area according to the preset path. In this process, according to the position signal fed back in real time by the positioning unit 354, the path of the target medicine spraying area is corrected online to ensure the consistency and uniformity of the medicine spraying.
[0072] Preferably, the third robot arm is a multi-axis industrial robot arm and is fixed to the side of the multifunctional workbench through a base 355 , specifically located on one side of the second workbench 311 in the medicine sprinkling area 23 .
[0073] Furthermore, the micro-injection head 353 can be a rubber-tipped dropper with scale lines, a micro-spray system or a micro-injection needle, etc., so as to achieve more precise control of liquid medicine application.
[0074] In order to ensure accurate positioning of the end effector during operation, the positioning unit 354 of the present disclosure may be composed of a processor and an infrared positioning device, wherein the processor is communicatively connected to the main control center module 10 for sending positioning detection signals.
[0075] In addition, a tray 356 with edges, such as a high-edge circular tray, is provided in the second workbench 311 in the spraying area 23 to prevent the liquid medicine from accidentally spilling onto the workbench or overflowing.

[0077] The servo motor 361 is electrically connected to the fourth mechanical arm 362, and is used to control the precise movement of the fourth mechanical arm 362. The hot melt unit 360 is fixedly mounted on the fourth mechanical arm 362, and the temperature sensing element is used to detect the real-time temperature of the hot melt unit 360, and feed back the detected temperature signal to the temperature control system, and the temperature control system compares the obtained temperature value with the preset temperature threshold, controls and adjusts the heat sewing temperature of the hot melt unit 360 within a suitable temperature range to avoid overheating or insufficient fusion.
[0078] Preferably, the hot melt unit 360 of the present disclosure may be a hot melt gun, an electric soldering iron, etc. In addition, in addition to hot melt processing, the present disclosure may also use ultrasonic welding technology and cold pressure bonding technology to achieve sealing and suturing of the applicator. The present disclosure does not impose any particular limitation on this.

Accordingly, a fifth workbench 314 is provided in the packaging area 26 for placing the workpiece after the second cutting.
[0080] In addition, the integrated system may also include a material placement area (not shown in the figure), which may be used to place and store film materials for preparing radiation protection applicators, such as transparent film materials, etc. According to actual production needs, the main control center module 10 may send a control instruction to control the second robot arm 34 to grab the film material placed in the placement area and move it to the heat stitching area 24.

Exemplarily, each working area is provided with a corresponding operating window 2013, for example, 10 closable operating windows 2013 are provided, so as to facilitate the operator to observe and perform auxiliary operations.
[0083] Preferably, the isolation cover 201 can be made of transparent glass or transparent acrylic material.
[0084] According to an embodiment of the present disclosure, a lighting system is disposed in the isolation cover 201 and is disposed on the isolation cover body 2010 and / or the first and second walls 2011 and 2012;

[0086] Another embodiment of the present disclosure also provides an automated preparation method for an anti-radiation applicator, in which the automated production system described in the aforementioned embodiment is adopted. The preparation method includes the following steps: placing workpieces to be cut, image acquisition and processing, first precision cutting, drug spraying, lamination, heat stitching, second precision cutting, and packaging.
[0087] Specifically, the preparation method may include the following steps:
[0088] Step S1: Obtain the calibrated workpiece to be cut and place it on the multifunctional workbench; in this step, first, the operator or technician determines the lesion area of the patient, and uses the material to be cut, such as cellophane, to stick on the patient's skin lesion to outline and calibrate the lesion to obtain the calibrated workpiece to be cut. In this process, in order to obtain a more accurate lesion edge contour, the lesion contour can be identified and calibrated based on image recognition technology, and the present disclosure does not impose any special restrictions on this.
[0089] The operator can place one or more calibrated workpieces to be cut on the first workbench in the multi-functional workbench. After they are placed stably, the main control center module can start the negative pressure fan installed under the first workbench to adsorb and fix the workpieces to be cut.
[0090] Step S2: The main control center module issues a control instruction to control the image acquisition module to collect image information parameters of the workpiece to be cut placed on the first workbench, and obtain first characteristic parameters about the workpiece, wherein the first characteristic parameters at least include posture information and edge contour information of the workpiece to be cut; the posture information may include the coordinates of each workpiece to be cut on the first workbench, and the edge contour information includes parameters such as the area, shape, and edge features of the workpiece to be cut.
[0091] Step S3: The collected first characteristic parameter is transmitted to the image processing unit. The image processing unit performs edge feature extraction and image segmentation on the first characteristic parameter based on the convolutional neural network U-Net model to identify the first edge contour of the target area.
[0092] Specifically, the image processing unit uses a convolutional neural network in deep learning to extract features from the image, and applies a U-Net model to finely segment the image to identify the first edge contour of the target area in the image; in this process, a large number of labeled scar images are required to train the network so that it can identify ROIs of different qualities and shapes. In this way, the automated production system can quickly process the images captured by the image acquisition module, quickly identify the ROI, and pass the recognition results to the next stage. In addition, in order to further improve the accuracy of ROI recognition, the calculation model can also be combined with the Canny or Sober operator optimization model algorithm to further accurately determine the ROI edge.
[0093] Step S4: Based on the identified first edge contour of the target area, the main control center module plans a first cutting path for the workpiece to be cut, controls the second slide to move and position, and at the same time, the first robot arm moves toward the workpiece to be cut on the first workbench, so that the shearing unit (such as a laser cutter) in the cutting module performs the first precision cutting on the workpiece to be cut;
[0094] Step S5: After the first cutting is completed, the workpiece after the first cutting is grabbed and transported to the second workbench in the spraying area by means of the second robot arm, and placed in a circular tray with an edge, and the workpiece in the tray is evenly coated with liquid medicine by using the spraying module;
[0095] Among them, the main control center module accurately calculates the amount of liquid medicine required for the workpiece to be applied based on the first characteristic parameter obtained by identification, transmits the liquid medicine to be applied to the micro-injection head through the liquid storage tube, and accurately controls the amount of liquid medicine delivered through the metering pump to achieve accurate drug supply. During the drug application process, the positioning unit set at the end of the third mechanical arm is used to position the end effector in real time and correct the drug application path online to ensure the consistency and uniformity of the drug spray and the therapeutic effect of the applicator.
[0096] Step S6: After the drug spraying is completed, the main control center module controls the second robot arm to move the workpiece sprayed with drugs to the heat stitching area for heat stitching operation. Before the workpiece sprayed with drugs is moved to the third workbench in the heat stitching area, it also includes the step of placing a layer of the first film to be heat stitched on the surface of the third workbench, for example, using the second robot arm to grab a first film material and place it on the surface of the third workbench, and then placing the workpiece sprayed with drugs on the surface of the first film. Optionally, the negative pressure fan is started to provide negative pressure adsorption force for the third workbench to ensure the positioning and fixation of the first film and the workpiece thereon; after this step, a second film material is placed on the upper surface of the workpiece sprayed with drugs, so as to form a sandwich structure of the first film-drug sprayed workpiece-second film.
