[0002] In routine pathology work, diagnosticians sometimes question the quantity, size, and origin of tissue within paraffin blocks. When the quantity and size of tissue within the block do not match the sampling description, it is difficult to determine whether the discrepancy is due to an error in the sampling description, natural fragmentation during tissue dehydration, tissue spillage during the unsealing and embedding process, tissue misalignment, or other unforeseen circumstances.

[0015] This utility model has the following technical effects:

[0016] This invention achieves full-process video recording of the embedding operation by integrating a camera assembly with the embedding machine body, establishing a traceable quality control data chain. The fixed-point layout of the camera assembly completely covers key operational nodes in the embedding area, simultaneously recording the opening of the embedding box, tissue positioning, and paraffin injection processes, effectively solving the deficiency of traditional manual operations that lack process evidence. The embedded design of the storage module and data bus forms a closed data flow, avoiding image data loss caused by external signal interference, and ensuring the authenticity and integrity of the original record.

[0017] The multi-degree-of-freedom adjustment capability of the rotatable multi-axis robotic arm overcomes the limitations of a fixed viewing angle, adapting to the imaging needs of embedding cassettes of different sizes through pose adjustment, and eliminating blind spots in operation where tissue edges are outside the field of view. The ring-shaped lighting scheme of the supplementary lighting group automatically compensates for light intensity in low-light environments, suppressing reflections and shadow interference in the embedding area and improving the imaging recognition of tissue texture features. The threaded sealing structure of the dust cover maintains lens cleanliness in dynamic working environments, preventing image blurring caused by wax mist particles. The multi-mode transmission design of the output interface is compatible with offline and online data management needs, building a scalable pathological image database. The two-way interactive mechanism of the touch screen simplifies the operation logic, integrating process monitoring and historical data retrieval. The timestamp generation unit establishes an irreversible link between image recording and standard time through hardware-level clock synchronization technology, strengthening the legal validity of medical data. The independent temperature control system with hot and cold zones achieves process synergy between maintaining paraffin fluidity and rapid solidification within a limited space, improving the quality stability of embedding molding.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Figure 1 A schematic diagram of a tissue embedding machine with integrated camera function provided for an embodiment of this utility model includes:

[0025] The embedding machine body 1 has a camera assembly 3 installed next to the wax outlet 2 of the embedding machine body 1. The camera assembly 3 is used to take pictures and / or record videos of the embedding area 4 located in the direction of the wax outlet.

[0026] The embedding machine body 1 has an integrated storage module inside, which is electrically connected to the camera component 3 via a data bus.

[0027] The embedding machine body 1 adopts a metal frame structure, with a wax melting zone connected to the wax outlet 2 at its top. A camera assembly 3 is fixedly mounted on the side of the wax outlet 2. The camera assembly 3 includes an industrial-grade CMOS sensor, and the lens axis is tilted at an angle to the direction of wax spray from the wax outlet 2, ensuring that the lens's field of view completely covers the working range of the embedding area 4. The embedding area 4 is located directly below the wax outlet 2 and is equipped with a liftable platform for placing the embedding cassette and tissue samples. The power supply line of the camera assembly 3 is arranged along the internal wiring channel of the embedding machine body 1, and the video signal line uses shielded twisted-pair cable connected to the motherboard slot.

[0028] The embedding camera body 1 has an embedded storage module, which consists of a solid-state drive and a cache chip, and is connected to the motherboard via a SATA data bus. The data bus adopts a layered cabling method, and the video stream transmission channel and the temperature control signal line are physically isolated to avoid electromagnetic interference causing image data distortion. The storage module has an independent heat dissipation channel, and the heat sink extends to the heat dissipation holes on the side wall of the embedding camera body 1 to ensure stability under long-term recording conditions.

[0029] When the operator starts the embedding procedure or begins manual embedding, liquid paraffin begins to be injected from the wax outlet 2, and the camera assembly 3 simultaneously activates video capture mode. Alternatively, video capture mode can also be activated simultaneously when the embedding box is opened. The CMOS sensor captures the entire process of opening the embedding box, tissue placement, and paraffin solidification in a line-by-line scanning manner. The video stream is compressed using H.265 encoding and written to the storage module. The storage module establishes a folder storage system named by date and automatically generates video index files containing operation time points. During the operation of the embedding machine body 1, the operator can observe the working status of the camera assembly 3 through the status indicator lights, and a buzzer alarm will be triggered in case of a malfunction.

[0030] This implementation optimizes the spatial layout, seamlessly integrating the image acquisition system into traditional embedding equipment, achieving visualized monitoring of the process without altering the original operational procedures. The metal frame structure provides a stable mounting base for the camera assembly 3, while the tilted lens layout effectively avoids paraffin splash contamination, and the shielded cable design ensures high-quality image transmission. A layered storage management system prevents data from different batches of samples from becoming mixed, and the heat dissipation structure extends the continuous operating time of the equipment. Overall, the solution significantly improves the traceability of the pathological embedding process.

[0031] Figure 2 This is a schematic diagram of a camera assembly structure provided in an embodiment of the present invention. In some embodiments, the camera assembly 3 includes a rotatable multi-axis robotic arm 31 and a camera body 32. The end of the rotatable multi-axis robotic arm 31 is fixedly connected to the camera body 32 by a locking bolt. The rotatable multi-axis robotic arm 31 is used to adjust the pose of the camera body 32.

[0032] The rotatable multi-axis robotic arm 31 is made of aluminum alloy, and its base is vertically fixed to the side wall of the wax outlet 2 of the embedding machine body 1 by four countersunk screws. The main body of the robotic arm can include three articulated links, and adjacent links are driven by a worm gear mechanism. A hexagonal adjustment knob extends from the end of the worm. The camera body 32 adopts a hemispherical shell design, and a flange is machined at the rear of the shell. Four screw holes are evenly distributed around the circumference of the flange, which are aligned with the screw holes of the mounting plate at the end of the rotatable multi-axis robotic arm 31. After the locking bolt passes through the mounting plate and the flange, the lock nut is screwed in and pre-tightened to the specified value using a torque wrench.

[0033] Each link of the rotatable multi-axis robotic arm 31 is internally equipped with a micro stepper motor, the motor output shaft of which is coaxially connected to the worm gear. Alternatively, the rotatable multi-axis robotic arm 31 can be adjusted manually. The stepper motor drive board is integrated inside the robotic arm base and communicates with the main control board of the embedding machine body 1 via a flat cable. When the operator presses the direction control key on the robotic arm housing, the main control board sends a pulse signal to the corresponding stepper motor, driving the worm gear mechanism to cause the link to produce pitch or rotation. The camera body 32 changes the shooting angle with the movement of the robotic arm, and its lens optical axis can rotate 360° horizontally and adjust within a range of ±45° vertically. After adjustment, the anti-loosening structure of the locking bolt can resist the torque generated by the weight of the robotic arm and prevent the position of the camera body 32 from shifting.

[0034] The structure adopts a modular assembly design, and the flange connection facilitates quick disassembly and replacement of the camera body 32. The worm gear transmission mechanism combines self-locking characteristics with precision adjustment capabilities, and the hexagonal adjustment knob supports manual fine-tuning. The three-section linkage layout expands the spatial movement freedom of the camera body 32, enabling it to adapt to the shooting needs of embedding boxes of different sizes. The aluminum alloy material reduces the overall weight of the robotic arm, lowers the load on the support structure of the embedding machine body 1, and ensures the robotic arm's resistance to deformation in high temperature and high humidity environments. The multi-axis collaborative adjustment mechanism allows operators to precisely control the lens angle, ensuring that there are no blind spots in the image coverage of the four key operation nodes in the embedding area.

[0035] Figure 3 This is a schematic diagram of another camera assembly structure provided by an embodiment of the present utility model. In some embodiments, a supplementary light group 33 is arranged in a ring around the lens of the camera assembly 3, and the supplementary light group 33 includes at least three LED beads.

[0036] The supplementary light assembly 33 is fixed to the front of the lens of the camera body 32. Three mounting slots are equally spaced on the inner circumference of the annular bracket. A thermally conductive pad is attached to the bottom of each mounting slot, and LED beads are embedded into the slot via clips, with the light-emitting surface of the beads facing the lens axis. The LED beads are spaced at 120° intervals, and their leads are soldered to a flexible circuit board. The circuit board is routed along the inner wall of the annular bracket and connected to the power interface of the camera body 32. A hemispherical frosted lampshade is fastened around the LED beads, with a waterproof gasket around the edge, and secured to the annular bracket with four countersunk screws.

[0037] The power supply line for the supplementary lighting unit 33 is led out from inside the camera body 32, with the positive and negative terminals passing through the pre-drilled holes in the annular bracket. The wires are covered with a high-temperature resistant silicone sheath, and the terminals are gold-plated to reduce contact resistance. The inside of the lamp cover is coated with a reflective coating to convert the direct light from the LED beads into diffused light. A strip-shaped heat dissipation hole is provided at the bottom of the annular bracket, and aluminum heat dissipation fins are welded inside the heat dissipation hole. The extension direction of the fins is aligned with the heat dissipation airflow of the embedding machine body 1.

[0038] When the camera body 32 starts shooting, the photosensitive sensor automatically detects the ambient light intensity of the embedding area 4. The control module adjusts the drive current of the LED beads based on the detection results, increasing the supplementary light brightness in low-light environments and activating dynamic noise reduction mode in strong light environments. The frosted lampshade ensures uniform light scattering, eliminating image overexposure caused by reflections from the wax on the tissue sample surface. Heat sink fins quickly conduct the heat generated by the LED beads to the main heat dissipation system of the embedding machine body 1, preventing light decay from occurring during prolonged operation.

[0039] The ring-shaped supplemental lighting structure breaks through the spatial limitations of traditional top-mounted lighting equipment, allowing light to cover the operating area from multiple angles along the lens axis. Evenly distributed LED beads, combined with a frosted lampshade, create a shadowless lighting effect, ensuring clear visibility of the internal texture of the embedded box. A dual heat dissipation design, using thermal pads and heat sinks, enhances the adaptability of the supplemental lighting unit 33, enabling stable operation in high-temperature and high-humidity environments. The modular assembly method facilitates individual replacement of damaged LED beads during later maintenance, reducing equipment operating costs.

[0040] Figure 4 This is a schematic diagram of another camera assembly structure provided by an embodiment of the present utility model. In some embodiments, a dust cover 34 is installed at the front end of the camera body 32, and the dust cover 34 is fixed to the camera body 32 by threads.

[0041] The dust cover 34 is fixed to the front end of the camera body 32 via a threaded connection. The front end of the dust cover 34 is a transparent observation window made of a high light transmittance material, and the rear end is equipped with a sealing ring that fits tightly against the housing of the camera body 32. When installing, tighten the dust cover 34 clockwise to the limit step; when disassembling, rotate it in the opposite direction to separate it.

[0042] The dust cover 34 features a multi-layered filtration structure, with an electrostatic adsorption layer near the observation window to capture wax mist particles. A guide groove is machined at the threaded connection to allow dust entering the gap to be discharged outwards along the groove. The transparent observation window surface is coated with an oleophobic coating to prevent wax from adhering and affecting imaging.

[0043] When the camera body 32 is in operation, the dust cover 34 effectively blocks wax residue and dust splashed during the embedding process. An electrostatic adsorption layer continuously attracts fine particles, preventing their deposition on the lens surface. Maintenance only requires unscrewing the dust cover 34 for overall cleaning; no separate lens cleaning is necessary. This structure significantly reduces equipment maintenance complexity while ensuring image clarity.

[0044] In some embodiments, the embedding machine body 1 is provided with an output interface panel 5, on which a USB interface 51 and / or a wireless transmission module 52 are arranged, and the USB interface 51 and the wireless transmission module 52 are electrically connected to the storage module respectively.

[0045] The output interface panel 5 is embedded in the front panel of the embedding unit body 1. The panel is made of anodized aluminum alloy substrate. The USB interface 51 uses a Type-C or USB-A standard interface, and its female connector is soldered onto an independent circuit board. The circuit board is connected to the expansion slot of the storage module via pin headers. The wireless transmission module 52 includes a Wi-Fi antenna and a Bluetooth chip. The antenna adopts a serpentine trace design on the PCB board, extending to the non-metallic area at the top of the embedding unit body 1. The power supply lines of the USB interface 51 and the wireless transmission module 52 are connected in parallel to the motherboard power layer, while the signal lines are connected to the data ports of the storage module using differential traces.

[0046] During operation, inserting a USB flash drive into USB interface 51 triggers the storage module's enumeration protocol, automatically mounting it as an external storage device. After the wireless transmission module 52 starts, it generates an independent SSID hotspot. Mobile terminals can then access the video file directory via a web browser. During data transmission, the ESD protection diode in USB interface 51 suppresses electrostatic interference, and the shielding cover of the wireless transmission module 52 reduces electromagnetic radiation leakage.

[0047] A rubber dust cover is provided on the edge of the interface panel, completely covering the USB interface 51 slot when closed. The antenna area of ​​the wireless transmission module 52 has a strip-shaped transparent window and is encapsulated in polycarbonate. This design achieves multi-mode compatibility for data export, with the physical interface and wireless transmission serving as backups for each other, ensuring data accessibility in different scenarios. The modular circuit layout reduces the risk of signal crosstalk, and the protective structure extends the interface's lifespan.

[0048] In some embodiments, the embedding machine body 1 is also equipped with a touch screen display 6, the surface of which is covered with an anti-glare glass layer.

[0049] The touch display screen 6 is integrated at the front end of the embedding machine body 1. The surface of the touch display screen 6 is covered with an anti-glare glass layer 61, and the edges of the glass layer are chemically tempered to enhance impact resistance. The inner surface of the anti-glare glass layer 61 is coated with a multi-layer anti-reflective film, and the outer surface is sprayed with an oleophobic coating to form a bidirectional optical optimization structure. The display screen driver board is connected to the video decoding unit of the storage module via a flexible ribbon cable, supporting real-time display of images captured by the camera component 3.

[0050] Operators can use touch gestures to access historical recordings in the storage module on the display screen and switch between video file directories from different dates. When the playback interface is clicked, the video stream is decoded by hardware and displayed in picture-in-picture format next to the operation parameter monitoring interface. The diffuse reflection properties of the anti-glare glass layer 61 suppress mirror reflections caused by direct sunlight from the laboratory ceiling lights, ensuring that details in dark areas of the image are clearly visible.

[0051] The built-in graphical interface of the display provides touch buttons for "Video Playback," "Capture Screenshot," and "Parameter Settings," which directly invoke the corresponding functions of the storage module upon clicking. The oleophobic coating of the anti-glare glass layer 61, when wiped with an alcohol swab, easily removes fingerprints and smudges, meeting medical equipment disinfection standards. This design integrates equipment control and image monitoring functions into a unified interface, allowing operators to perform embedding quality checks and process traceability without an external monitor. The bidirectional optical structure maintains image visibility even in complex lighting conditions, improving human-computer interaction efficiency.

[0052] In some implementations, the storage module includes a timestamp generation unit, the clock signal input of which is connected to a crystal oscillator circuit, and the data output of which is connected in parallel with the video stream writing end of the camera component.

[0053] The timestamp generation unit is integrated on the circuit board of the storage module. Its core is a real-time clock chip, with the chip pins soldered to a six-layer PCB. The crystal oscillator circuit uses a temperature-compensated crystal package, fixed to the vibration-resistant area of ​​the circuit board with epoxy resin. The output signal is shaped by a phase-locked loop circuit before being input to the real-time clock chip. The data lines of the video stream writing end are connected in parallel to the serial communication interface of the timestamp generation unit, forming a bidirectional data channel.

[0054] When camera component 3 starts recording, the real-time clock chip synchronously reads the reference clock signal from the crystal oscillator circuit and generates an ASCII encoded data packet containing the year, month, day, hour, minute, and second. The encoded data is inserted into the video stream frame header via hardware-level DMA transfer and written to the storage module sector along with the image data. During playback, the timestamp information is overlaid as a semi-transparent watermark in the upper left corner of the video screen, and the watermark font uses anti-aliasing rendering technology.

[0055] The temperature-compensated characteristics of the crystal oscillator circuit keep the clock error within 0.5 seconds per day, and the timing is maintained by a button battery after power failure. The timestamp data packet employs a cyclic redundancy check (CRC) mechanism; the storage module automatically compares the timestamp sequence with the video frame number, triggering a check error flag when an anomaly is detected. This design ensures that the time recording of the operation process is synchronized with the standard time source, providing an immutable time reference for pathology quality control. The intelligent overlay mechanism of the timestamp watermark avoids obscuring critical operation areas while meeting the archiving requirements of medical images.

[0056] In some implementations, an operating console 7 is also included;

[0057] The operating table includes a cold table 71 and a hot table 72. The cold table 71 has a semiconductor cooling chip embedded inside, and the hot table 72 has a resistance heating wire arranged inside. The semiconductor cooling chip and the resistance heating wire are respectively connected to independent temperature control circuits.

[0058] The operating platform 7 is embedded in the platform below the embedding area 4 of the embedding machine body 1, and its surface is made of aerospace aluminum material with a honeycomb heat dissipation structure. The cold stage 71 has a semiconductor cooling chip laminated inside, and the cold end of the cooling chip is tightly attached to a pure copper heat spreader plate through thermal grease, while the hot end is welded with an aluminum heat dissipation fin assembly. The resistance heating wire of the hot stage 72 is embedded in the mica plate sandwich in a serpentine pattern, and the upper and lower surfaces of the mica plate are covered with an aluminum nitride ceramic insulation layer.

[0059] The temperature control circuit of the cold stage 71 adopts a PID closed-loop control strategy, with the temperature sensor embedded in a blind hole in the center of the heat spreader, providing real-time temperature data feedback to the main control unit. The temperature control circuit of the hot stage 72 is equipped with an overcurrent protection module, controlling the heating wire's on / off state via a solid-state relay. The two temperature control circuits are wired independently, with power supply lines led from the power module of the embedding machine body 1, and signal lines connected to different channels on the main control board using twisted-pair shielded cables.

[0060] When the embedding process begins, the hot stage 72 is preheated to the set temperature to maintain the fluidity of the paraffin; the cold stage 71 initiates rapid cooling after tissue positioning to accelerate paraffin solidification. A honeycomb heat dissipation structure enhances the heat exchange efficiency of the cold stage 71, and the aluminum heat dissipation fins work in conjunction with the air-cooling system of the embedding machine body 1. The aluminum nitride ceramic layer ensures that the surface temperature distribution uniformity of the hot stage 72 is controlled within ±1℃. This zoned temperature control design enables coordinated hot and cold operation in the embedding process, avoiding the impact of high temperatures on already embedded samples while ensuring that newly injected paraffin maintains a suitable viscosity. Independent circuit layout completely isolates electromagnetic interference between the hot and cold systems, improving temperature control stability.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
