[0028] The following will combine the drawings in the embodiments of the present application to further describe the present application. Figure 1 The technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments.

[0029] In order to better illustrate the present application, some nouns are now explained:

[0030] Flexible support working medium: refers to the working medium used to realize specific functions in a device with flexible support structure. These working media usually work with the flexible support structure to meet the requirements of the device in flexibility, functionality and stability, etc.

[0031] EMBODIMENT

[0032] Figure 1The structure of the low-temperature shaping device for medical printed parts provided by the embodiment of the application is shown in the schematic diagram. The device comprises a shaping cabin, a temperature control module, an edge plasticity unit, and a moving support. The shaping cabin is mounted on the moving support, which facilitates flexible deployment in different medical scenarios. The temperature control module and the edge plasticity unit are both arranged inside the shaping cabin. The temperature control module is used to receive operation instructions transmitted by the control terminal and perform self-calibration detection, and at the same time, it feeds back temperature distribution data to the control terminal. The edge plasticity unit processes the edge area of the medical printed parts through a flexible support working medium, ensuring that the edge plasticity precision is within the preset range.

[0033] Firstly, the shaping cabin, as the main structure of the entire device, not only provides a working space, but also realizes efficient shaping of the medical printed parts through the temperature control module and the edge plasticity unit inside it. The outer wall of the shaping cabin is made of heat insulation material to reduce the influence of the external environment on the internal temperature field. The inner wall of the cabin is provided with multiple sensors for real-time monitoring of the changes in temperature and humidity inside the cabin, ensuring the stability of the shaping process. The design of the moving support enables the shaping cabin to be quickly transferred in different medical scenarios, such as from the operating room to the ward or the laboratory, thereby meeting the demand for rapid preparation of personalized medical instruments.

[0034] The temperature control module is one of the core components of the device. The temperature control module mainly comprises a thermal management unit, a heating unit, and a shaping mold. The thermal management unit is installed inside the shaping cabin through a damping support, and is used to receive operation instructions transmitted by the control terminal and transmit the operation instructions to the heating unit. At the same time, the thermal management unit also receives heating state information and temperature feedback data transmitted by the heating unit, processes them, and generates a temperature distribution map and plasticity effect information, and finally transmits these data to the control terminal. The thermal management unit also includes a thermal field analysis module and a data processing module. The thermal field analysis module is responsible for extracting thermal field distribution data and plasticity effect images from the temperature feedback data, while the data processing module performs filtering processing on these data to generate clear temperature distribution maps and shaping effect information. The data processing module uses a high-performance embedded processor, which can quickly complete complex data processing tasks.

[0035] The heating unit is an important component of the temperature control module, and its main function is to control the working power of the heating array in the shaping mold according to the operation instruction and generate corresponding heat energy. The heating unit includes a drive controller and a thermal field scanner. After receiving the operation instruction transmitted by the thermal management unit, the drive controller transmits it to the shaping mold through the thermal field scanner, and at the same time feeds back the heating state information to the thermal management unit. The drive controller generates a pulse modulation signal and a thermal field power control signal according to the operation instruction, adjusts the working power of the heating array in the shaping mold through the thermal field power control signal, so that it reaches the target power. The thermal field scanner drives the internal thermoelectric conversion components to operate according to the pulse modulation signal, and transmits the generated heat energy to the shaping mold. In addition, the heating unit also contains a temperature sensor for collecting the current working temperature of the heating array, and transmitting the collected temperature data to the drive controller. The drive controller will judge whether the current working temperature matches the target power, and if not, it will generate an alarm signal and trigger the alarm device to issue a prompt.

[0036] The shaping mold is the execution component of the temperature control module, and its internal structure includes a heating array, a multi-channel thermal field adjustment module and a heat source distributor. The heating array switches between heating state and cooling state according to the operation instruction, and is respectively used for applying a first thermal field signal to the surface of the medical print and receiving a second thermal field signal. The multi-channel thermal field adjustment module is responsible for converting the first heat energy flow provided by the heat source distributor into a third thermal field signal, and generating the first thermal field signal after distributing and modulating it. The multi-channel thermal field adjustment module includes a thermal field generation component, a thermal energy amplification component, a multi-channel thermal field distribution component, a subarray synthesis board, a T / H component array, a switching component and a digital processing module. The thermal field generation component generates a third thermal field signal based on the operation instruction after receiving the first heat energy flow; the thermal energy amplification component amplifies the third thermal field signal; the multi-channel thermal field distribution component divides the amplified third thermal field signal into several fourth thermal field signals, and converts the second subarray signal transmitted by the subarray synthesis board into several sixth thermal field signals; the subarray synthesis board converts each fourth thermal field signal into a first subarray signal, and converts the fifth thermal field signal transmitted by the T / H component array into a corresponding second subarray signal; the T / H component array generates a first thermal field signal after distributing and modulating the first subarray signal, and generates a fifth thermal field signal after amplifying, distributing and modulating the second thermal field signal; the switching component receives the second subarray signal or each sixth thermal field signal, and selects to perform superposition operation or difference operation on it, to generate a superposition signal or a difference signal; the digital processing module converts the superposition signal, the difference signal or the second subarray signal into a corresponding digital signal to obtain temperature feedback data. This multi-stage adjustment mechanism can effectively improve the temperature control precision and ensure that the shaping effect of the medical print reaches the expectation.

[0037] The edge plasticity unit is another important component of the device, and its main function is to transport flexible support working medium to the edge area of the medical print to improve the edge plasticity accuracy. The selection of the flexible support working medium needs to consider its flowability, viscosity, and thermal stability, etc. to ensure that it can still maintain good performance in a low temperature environment. In practical applications, the flexible support working medium is usually composed of a silica gel base material and functional additives, where the silica gel base material provides the basic physical properties, and the functional additives are used to improve the flowability and thermal conductivity of the working medium. The edge plasticity unit uniformly coats the flexible support working medium on the edge area of the medical print by precisely controlling the flow and pressure of the flexible support working medium, thereby achieving optimal processing of the edge plasticity.

[0038] To further illustrate the specific implementation process of the present application, the following detailed description is combined with an actual application scenario.

[0039] A hospital needs to customize a personalized orthopedic brace for a patient. The doctor uses 3D printing technology to produce a preliminary medical print and places it in the shaping cabin. The control terminal generates operation instructions according to the patient's physiological data and orthopedic requirements, and transmits them to the temperature control module. After receiving the operation instructions, the temperature control module first performs self-calibration detection to ensure that all components are in normal working condition. Then, the thermal management unit transmits the operation instructions to the heating unit, and the drive controller generates pulse modulation signals and thermal field power control signals according to the operation instructions, and drives the thermal electric conversion assembly to run through the thermal field scanner, and transmits the generated heat energy to the shaping mold. The heating array in the shaping mold generates a first thermal field signal in the heating state and acts on the surface of the medical print, and receives a second thermal field signal returned from the surface of the medical print in the cooling state, and generates temperature feedback data after processing. After the temperature feedback data is filtered by the data processing module, a temperature distribution map and plasticity effect information are generated and transmitted to the control terminal for the doctor's reference. At the same time, the edge plasticity unit uniformly coats the flexible support working medium on the edge area of the medical print to ensure that the edge plasticity accuracy reaches the preset range. After the entire shaping process is completed, the doctor takes out the finished orthopedic brace and finds that its shape and size fully meet the design requirements, and the edge area is smooth and flawless.

[0040] In the above implementation process, the device significantly improves the shaping effect of the medical printed part by optimizing the edge plasticity details and improving the temperature control accuracy. In addition, the modular design of the device makes the connection and signal transmission between components more efficient, simplifies the operation process and reduces the risk of unstable material performance. In particular, the application of the thermal field stabilizing assembly ensures that the working power of the heating array is always maintained between 50% and 100% of the rated power, thereby avoiding shaping failure caused by power fluctuations. At the same time, the introduction of the data storage module and the power management module further improves the reliability and practicability of the device, providing strong technical support for clinical practice.

[0041] In summary, the present application realizes efficient and accurate shaping of medical printed parts by combining the temperature control module, edge plasticity unit and shaping cabin, meeting the demand of clinical practice for rapid preparation of personalized medical devices.
