Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a field modular minimally invasive surgical treatment system. Background Technology

[0002] Modern warfare and disaster relief place extremely high demands on the timeliness of treating the wounded.

[0003] However, existing frontline surgical equipment has the following significant drawbacks: traditional equipment relies on generators and specialized consumables, and once supplies are cut off or the battery is depleted, the equipment immediately becomes inoperable. Furthermore, changing the power supply during surgery can easily damage the sterile area. It also lacks the ability to handle surgical fumes and harmful sterilization gases in enclosed field environments (such as tents and armored vehicles), seriously threatening the health of medical personnel. At the same time, the electromagnetic signals emitted by the equipment can easily expose targets. In the high-pressure battlefield environment, the simple button design can easily lead to accidental activation (such as accidental electrosurgical cuts), causing medical accidents. Traditional stents cannot be fixed in non-standard environments (ground, stretcher). When the specialized tubing is depleted, the equipment cannot use general medical supplies for emergency use.

[0012] Compared with the prior art, the beneficial technical effects of this application are: 1. Split-type architecture and sterile hot-swappable power system (solving the problem of continuous operation) This invention moves the weight-concentrated battery, high-frequency generator, and pump to a backpack / waist-mounted external unit, reducing the weight of the handheld device to below 200g and greatly reducing the burden on the operator.

[0013] Aseptic hot-swappable: The external unit has a ejector battery compartment on the back, allowing non-sterile personnel (such as circulating nurses) to replace the battery without disturbing the sterile surgical area.

[0014] UPS protection: Built-in supercapacitor or backup small battery as UPS to ensure "zero-second" power failure of the system during the removal of the main battery, maintain the operation of control circuits and sensors, and ensure the continuity of surgery.

[0015] 2. High versatility and high fault tolerance in fluid management (solving logistical and fault-tolerant issues) Universal interface compatibility: The fluid interface is designed with a barbed, stepped Luer-lock compatible structure. When the dedicated sterile tubing is exhausted, medics can directly use readily available IV tubing or catheters to connect to the system, greatly improving the system's battlefield survivability.

[0016] Anti-clogging backflushing: By monitoring the pressure change rate of the negative pressure circuit, when the pipeline is detected to be blocked by blood clots or bone fragments, the system automatically executes pulse-type reverse water injection to quickly unclog the pipeline.

[0017] Intelligent smoke extraction: The handle integrates a smoke sensor, which automatically increases negative pressure the moment tissue is cut, and works with the ULPA filter in the backpack unit to completely remove and filter carcinogenic smoke and viral aerosols.

[0018] 3. Dual safety mechanisms to prevent accidental touch (to solve the problem of accidental operation in high-voltage environments) Considering the chaotic and tense battlefield environment, the handheld actuator employs a dual-safety ... Physical layer: High-damping mechanical buttons provide clear tactile feedback.

[0019] Logic layer: The controller monitors the data of the built-in IMU (Inertial Measurement Unit) of the handle in real time. If the handle is detected to be in free fall, violent shaking or non-grip posture, the system will automatically lock the energy output; and the energy will only be output if the finger is pressed continuously for more than a preset time (such as 200ms).

[0020] 4. Tactical concealment and environmental adaptation (solving survival and deployment issues) Radio silence: The system supports physical cable connections. When a cable is inserted, all radio frequency modules are physically powered off to prevent enemy electronic reconnaissance and location.

[0021] Multi-adaptive fixation: The pneumoperitoneum-free device base integrates ratchet clamps, ground nails, and suction cups, which can quickly establish a surgical platform on a stretcher, muddy ground, or vehicle wall.

[0022] Offline AI assistance: The AR glasses have a built-in independent computing chip, which can still identify bleeding points and project anatomical navigation based on the local database when the network is offline. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Fully Silent Mode and Dual-Mode Communication Architecture It includes an electromagnetic shielding structure, which interacts with data through a central intelligent control terminal 100 and has an adapter interface that is compatible with general medical supplies when special consumables are exhausted. The electromagnetic shielding structure includes a central intelligent control terminal 100, a split surgical execution module 200, a minimally invasive visualization and operation module 300, an environmentally adaptable sterilization module 400, and an intelligent auxiliary interaction module 500. Central Intelligent Control Terminal 100: As the core processing hub of the system, it is responsible for data bus control, image processing and coordination of various subsystems; Split-type surgical execution module 200: includes a lightweight handheld execution end 210 and an external functional unit 220 connected via a flexible optoelectronic hybrid umbilical cable 230. The external functional unit 220 adopts a backpack or waist-mounted design. Minimally invasive visualization and operation module 300: It adopts a gas-free suspension arm 310 and is equipped with a multi-adaptive fixing base 320 to adapt to complex outdoor surfaces; Environmentally Adaptive Sterilization Module 400: Driven by a built-in power supply, it features a self-cleaning emission mechanism for harmful gases and a door safety interlock mechanism; Intelligent Assistive Interaction Module 500: Provides deep lighting, bone conduction communication, and edge computing-based offline augmented reality navigation. The central intelligent control terminal 100 includes a magnetic physical data interface 101 and a wireless communication module 102; Magnetic physical data interface 101: Physical connection carrier: It carries fiber optic image transmission, differential cable control signal transmission, and power supply line low-voltage power transmission, realizing wired hard connection between the central terminal and the backpack unit, sterilizer, and AR head-mounted display. Silent Trigger Detection: The interface has a built-in detection pin. When the cable is inserted, the pin level is pulled low, sending an interrupt signal to the main controller and automatically triggering the radio silent mode. Outdoor protection: Magnetic quick-release structure, waterproof, dustproof and oil-proof, no need for precision thread tightening, can be quickly plugged in and unplugged even when wearing sterile gloves; optoelectronic composite integration reduces the number of wires and reduces the risk of tangling in the field; Signal isolation function: Fiber optic isolation of electromagnetic interference, wired transmission with no radio frequency radiation throughout, suitable for the concealment requirements of special operations; Wireless communication module 102: Wireless data transmission: It integrates Wi-Fi, Bluetooth and microwave image transmission, enabling wireless interconnection between the terminal and various modules in wire-free scenarios, which is suitable for rapid deployment and temporary mobile treatment sites; Tactical control function: When the magnetic physical data interface 101 physical cable is connected, the main controller directly cuts off the power supply of this module, completely shuts down the radio frequency transmission, eliminates electromagnetic signal leakage, and avoids enemy electronic reconnaissance and positioning. Offline switching logic: When the wireless signal is interrupted or the latency is too high, the system automatically disables the wireless module and switches to local edge computing for offline operation without interrupting the surgical procedure.

[0033] like Figure 1 As shown, this system uses a rugged tablet computer as the central intelligent control terminal 100.

[0034] Physical connection structure: The control terminal is equipped with a magnetic military aviation plug interface or a ruggedized Type-C interface on the side. When the terminal is physically connected to the backpack functional unit, sterilizer and AR head-mounted display through a special optoelectronic hybrid cable, the detection pin level in the connector is pulled low.

[0035] Silence Logic: When the system firmware detects a low level, it triggers an interrupt service routine, immediately cutting off the LDO power supply to Wi-Fi, Bluetooth, and any wireless image transmission modules, and transmitting data only through optical fiber or differential signal lines. At this time, the electromagnetic radiation intensity of the system to the outside world is reduced to the background noise level, meeting the "radio silence" requirements of special operations.

[0036] Example 2: Design of Split-Type Surgical Module and Anti-Accidental Touch Handle The split-type surgical execution module 200 includes a lightweight handheld execution end 210 and an external functional unit 220 connected via a flexible optoelectronic hybrid umbilical cable 230. The external functional unit 220 adopts a backpack or waist-mounted design, with the energy, fluid, and high-frequency generators mounted on the back. It is a lightweight surgical operation end, suitable for long-term field minimally invasive electrosurgical procedures. It achieves physical separation between the sterile area and the non-sterile area of ​​the energy / pump body, solving pain points such as intraoperative power replacement in the battlefield, pipeline blockage, surgical smoke, and accidental touch risks. Handheld Execution Terminal 210: Surgical operating device: The surgeon holds and operates the device to perform minimally invasive procedures such as electrocautery, electrocoagulation, tissue irrigation, and negative pressure smoke suction; made of lightweight PEEK material, the entire device weighs only 145g, making it less tiring to operate for a long time.

[0037] Signal acquisition hub: integrates buttons, IMU posture sensor, optical smoke sensor, and fluid interface to transmit grip posture, button triggering, and smoke concentration data to the central terminal in real time.

[0038] Aseptic operation design: The entire device can be sterilely wrapped in one go, with only the front end contacting the surgical field. All sensing and control circuits are sealed and waterproof, and can be wiped and disinfected with disinfectant. The handheld actuator 210 includes a high-damping anti-accidental touch button 211, an IMU inertial measurement unit 212, an optical smoke sensor 213, and a universal fluid interface 214; High-damping anti-accidental touch button 211: The first layer of physical protection against accidental touches: a high-damping silicone structure with a trigger force of 5N, which is 2-3 times the force of ordinary medical buttons. Slight touches or collisions will not trigger the energy output accidentally. Layered tactile feedback: The double-layered spring has a two-stage tactile feel. There is no output when lightly pressed, and a button signal is sent only when fully pressed, giving the operator a clear tactile cues. Safety logic input source: Sends press duration and pressure signals to the handle MCU, and uses IMU attitude data to achieve dual confirmation triggering; IMU (Inertial Measurement Unit) 212: Real-time posture monitoring: Continuously collects handle acceleration and angular velocity to determine handle status: stable grip, violent shaking, free fall, intraoperative shaking; The second layer of logic-based accidental touch prevention: In the event of a violent collision or a drop from the hand, the high-frequency energy output is immediately locked. Electrosurgical cutting / coagulation is only allowed if the handle is in a stable position and the button is pressed for more than 200ms. Battlefield anti-interference capability: Filters out vibration interference caused by field bumps and casualty movement, avoiding accidental shutdown or accidental discharge. Optical smoke sensor 213: Real-time intraoperative smoke detection: Collects the electrosurgical smoke and bioaerosol concentration generated in the surgical field and uploads it to the MCU fluid control logic in real time; Negative pressure adaptive control: When the smoke concentration increases, the negative pressure pump speed is automatically increased to increase the suction flow and quickly remove carcinogenic smoke and viral aerosols; when the concentration is low, the pump power is reduced to save battery energy. Advantages of front-end acquisition: It is placed at the entrance of the smoke channel of the handle, which can detect smoke in the first time and has a response speed much faster than the back-end pipeline detection; Universal fluid interface 214: Luer lock + three-stage pagoda barbed composite connector; Standard consumables compatibility: Inner standard Luer locking female head, compatible with original factory-dedicated sterile flushing and suction tubing, threaded locking to prevent detachment and leakage; Compatible with general emergency supplies: The outer layer has a three-level pagoda barb structure. When special consumables are exhausted, they can be directly connected to ordinary medical infusion tubes, blood transfusion sets, and urinary catheters. The interference-fit barbs seal the tubes and prevent leakage or detachment under -80kPa negative pressure. Integrated dual-channel function: The same connector integrates two pipelines: flushing fluid input and waste liquid fume suction, simplifying handle wiring and reducing pipeline tangling in the field; The external functional unit 220 includes an ejector battery compartment 221, a main battery pack 222, a UPS supercapacitor module 223, a phase change heat dissipation layer 224, and a gas-liquid separation and ULPA filter box 225. External Functional Unit 220: Back / Waist Mount Main Unit Rear-mounted load for weight reduction: By placing the battery, high-frequency generator, vacuum pump, flushing pump, and filter box all at the rear, the weight of the handheld end is significantly reduced, making it suitable for soldiers to carry and move for extended periods.

[0039] Mounting compatibility: Compatible with tactical vest MOLLE webbing, can be carried on the back or waist, suitable for various combat deployment scenarios such as foot transport, vehicle transport, and stretcher transport.

[0040] Non-sterile zone design: The battery compartment and operation buttons are all located on the non-sterile side of the back, allowing patrolling personnel to replace batteries and repair equipment without damaging the sterile surgical area.

[0041] Centralized heat source control: The internal high-power heating elements are centrally arranged, and a phase change heat dissipation layer is used to suppress infrared heat radiation, reducing the risk of exposure to infrared detection on the battlefield; Ejector-type battery compartment 221: Quick battery swapping mechanical structure: Spring-loaded latch, press the release button on the back to pop out the main battery, allowing for one-handed installation and removal without tools; The core design features sterile isolation: it is located entirely on the back of the carrying unit, away from the operator's sterile operating surface, so that the sterile area is not touched during battery replacement, thus avoiding the disruption of the sterile environment during the operation. Electrical safety pin: Built-in elastic conductive pin ensures stable contact during battery insertion and removal, preventing arcing and power outage impacts, and enables zero-interruption power replacement during surgery when used with a UPS module; Main battery pack 222: The system's main power supply provides power to the high-frequency generator, vacuum pump, peristaltic pump, terminal, and AR head-mounted display, enabling continuous surgery in the field without mains power for extended periods. Modular and replaceable: Standardized battery specifications, multiple batteries can be used in rotation, supporting batch replenishment and rapid replacement at the front line; Protective design: explosion-proof shell, overcharge and over-discharge protection, adaptable to high and low temperatures and impact battlefield environments; UPS Supercapacitor Module 223: Uninterrupted power supply during surgery: The capacitor power supply is switched within 10μs when the main battery is removed, maintaining the main control MCU, sensors and display screen to work continuously for at least 5 minutes, so that the surgical operation will not be interrupted by power failure. Low-energy maintenance mode power supply: During the battery swapping stage, the high-frequency output of the electrosurgical unit and the high-power operation of the pump group are automatically turned off, and only the basic functions of monitoring, display and sensing are retained to extend the battery life; Automatic power replenishment: The main battery is continuously and evenly charged when it is in place, always fully charged and ready to go, without the need for manual intervention; Phase change heat dissipation layer 224: High-power heat absorption: When the high-frequency generator and pump set are working continuously and heating up, a large amount of heat is absorbed through the phase change of paraffin to control the surface temperature of the outer shell and avoid burns to the operators. Infrared concealment tactics: Suppressing the high-temperature thermal imaging characteristics of equipment surfaces, reducing the probability of being detected by enemy infrared reconnaissance equipment, and adapting to covert combat scenarios; Passive cooling with no noise: No fan required, no extra noise, no extra electromagnetic radiation, suitable for silent treatment; Gas-liquid separation and ULPA filter cartridge 225: Integrated in the middle section of the negative pressure suction pipeline of the external functional unit 220, it is divided into two parts: a pre-gas-liquid separator and a post-ULPA ultra-low penetration filter element. It is the core integrated component of the entire field minimally invasive system for fluid safety, equipment protection and personnel protection. Flexible optoelectronic hybrid umbilical cable 230: Split unit connection carrier: connects the handheld actuator 210 and the backpack unit 220, and synchronously transmits power, control signals, surgical field images and fluid lines.

[0042] Flexible and bend-resistant: Medical flexible cables can be repeatedly bent without breaking, allowing surgeons to move freely without restriction during surgery.

[0043] Opto-isolation: Fiber optics transmit images, while metal cables transmit electrical energy and control signals, isolating electromagnetic interference from high-frequency electrosurgical units and preventing image distortion and sensor false alarms.

[0044] like Figure 2 and Figure 3 As shown, the surgical execution module is divided into a handheld end and a backpack end.

[0045] The carrying end is the external functional unit 100: it adopts a tactical vest mounting design compatible with the MOLLE system, and integrates a 400kHz high-frequency generation circuit, a peristaltic pump for rinsing, and a diaphragm vacuum pump for suction. The inner wall of the outer shell is lined with paraffin-based PCM material with a phase change temperature of 45°C, which is used to absorb heat during high-power operation and prevent the exposure of infrared thermal imaging features.

[0046] The handheld device features an anti-accidental touch design: Structural layer: The outer shell is injection molded from PEEK and weighs 145g. A high-damping silicone pad is used beneath the cutting and clotting buttons, with an actuation force set to 5N, approximately 2-3 times that of ordinary buttons, requiring significant force to press.

[0047] Dual confirmation logic: The controller PCB board integrates a 6-axis IMU, model MPU6050. The MCU reads acceleration and angular velocity data in real time. The algorithm sets a threshold: when the controller is detected to be in free fall or violent collision, the software locks the output. Only when the controller is in a relatively stable state and the button signal duration T>200ms, the MCU sends a PWM enable signal to the high frequency generator.

[0048] Example 3: Aseptic Hot-Swapping and UPS Power Management like Figure 2 As shown, the power system design for the back-end is as follows: Mechanical structure: The main battery pack 100 is installed in an open slot on the back plate. The slot is equipped with a spring pin and a mechanical lock. Pressing the red release button on the back will pop out the battery. This operating area is located on the operator's back and is a non-sterile area, which can be operated with the assistance of a colleague.

[0049] UPS circuit: The power management module is connected in parallel with a supercapacitor bank. When the main battery is in place, the circuit performs equalization charging of the capacitor. When the main battery is disconnected, the MOSFET switch turns on the capacitor circuit within 10μs to supply power to the main control MCU, sensors and display screen.

[0050] Logical flow: The main battery was detected to have been removed.

[0051] Switch to supercapacitor power supply.

[0052] The system enters "Low Power Maintenance Mode": high-frequency power output is turned off, the main motor is turned off, and the screen brightness is reduced to 20%.

[0053] A new battery has been detected. Full-function mode has been restored.

[0054] Example 4: Highly versatile fluid interface and anti-clogging logic like Figure 4 and Figure 5 As shown, this addresses the shortage and blockage of field supplies.

[0055] Universal interface structure: A composite connector is designed for the rinsing and suction ports at the tail of the handle.

[0056] The innermost layer is a standard Luer head, compatible with standard syringes and medical tubing.

[0057] The outer layer has a three-tiered pagoda barb structure with outer diameters of 3mm, 4mm, and 5mm respectively.

[0058] Effect: When the special tubing is used up, the tubing of the infusion set or the urinary catheter can be cut directly and the tube can be tightly fitted onto the pagoda connector. The barbed structure ensures that it will not leak or fall off under a negative pressure of -80kPa.

[0059] Adaptive backwashing: A pressure sensor is connected in series in the negative pressure circuit.

[0060] Blockage criterion: When the vacuum pump reaches its ultimate vacuum level and the duration t > 100 ms.

[0061] Action sequence: The MCU command stopped the suction pump (vacuum pump).

[0062] The MCU commands the flushing pump (peristaltic pump) to reverse or open the bypass solenoid valve to introduce saline solution.

[0063] The flushing pump outputs three pulses at maximum speed (0.5s each, 0.2s interval), generating instantaneous high-pressure water flow to impact the front end of the pipeline.

[0064] Restore the suction pump to operation.

[0065] Example 5: Multi-adaptive gas-free fixation base Minimally Invasive Visualization and Operation Module 300: A complete set of gasless minimally invasive suspension imaging units that replaces traditional pneumoperitoneal laparoscopic equipment, eliminating the need for artificial pneumoperitoneum; equipped with multi-form fixation bases, it can quickly set up a minimally invasive surgical field of view on various non-standard planes in the field to complete abdominal suspension and real-time intraoperative imaging. 310 pneumoperitoneum-free suspension arm: Abdominal traction to expose the surgical field: A mechanical traction structure is used to replace CO2 pneumoperitoneum, enabling minimally invasive surgery to be performed in the field without gas cylinders or gas sources, saving the burden of transporting and resupplying gas cylinders.

[0066] Imaging equipment: The front end of the suspension arm is equipped with an endoscope camera and a deep illumination source, which is stably fixed outside the abdominal incision to provide a continuous and clear surgical field image.

[0067] Multi-angle adjustment: The multi-joint robotic arm can rotate 360° and adjust its height and position to adapt to patients of different body sizes and different surgical sites. Multi-adaptive mounting base 320: a full-range support base for the suspension arm, integrating three fixing mechanisms: ratchet clamping, folding ground stakes, and vacuum suction cups. One device can adapt to all common deployment surfaces in the field without the need for additional bracket accessories; The multi-adaptive mounting base 320 includes a ratchet gripper 321, a folding ground stake 322, and a vacuum suction cup pump 323; Ratchet gripper 321: Tubular carrier fixing: bidirectional V-shaped jaws, rotating handwheel ratchet locking, suitable for round tubes with diameters of 10–40mm, such as field stretcher poles, cot rails, and armored vehicle pipelines; Quick assembly / disassembly function: ratchet one-way locking, reverse lever one-click release, clamping / disassembly completed in 3 seconds, rapid deployment on the battlefield; Folding pegs 322: Anchoring on soft ground: Three 15cm alloy steel barbed nails are distributed in a triangle. They can be pressed into the soil, grass, and sand by stepping on them, and are resistant to pull-out and tipping. Storage and portability: When not in use, it folds inward and is stored inside the base, without taking up extra space, making it convenient to carry and transport. Vacuum suction pump 323: Fixation on hard and smooth surfaces: Built-in manual vacuum pump, press to remove air from inside the suction cup, adsorb the inner wall of the container, the roof of the armored vehicle, and the metal operating table, and can withstand a vertical pulling force of 20kg; Non-damaging fixation effect: The silicone contact surface of the suction cup will not scratch the metal or plastic housing, and there is no residue after disassembly.

[0068] like Figure 6 As shown, the base of the pneumoperitoneum-free suspension arm 310 adopts a modular mechanical claw design.

[0069] State A (ratchet clamping): Tighten the two-way jaws by rotating the handwheel. The inner side of the jaws has a V-groove, which can firmly grip round tubes with a diameter of 10-40mm (such as field stretcher handles and cot legs).

[0070] State B (Ground nail anchoring): Three 15cm long alloy steel nails protrude from under the base, arranged in a triangle. On soil or grass, the steel nails are pressed into the soil by stepping on the base pedal, utilizing the barbed structure to resist pull-out.

[0071] State C (Vacuum Adsorption): The base integrates a manual vacuum pump suction cup. On the smooth walls of the container or the roof, press the pump button to evacuate air; it can withstand a vertical pull of 20kg.

[0072] Example 6: Sterilization Safety Interlock and Self-Cleaning The environmentally adaptable sterilization module 400 includes a sterilization chamber 401, a door electromagnetic interlock device 402, an ozone and hydrogen peroxide sensor 403, and a catalytic decomposition self-cleaning box 404. Sterilization chamber 401: Instrument sterilization enclosed space: accommodates minimally invasive consumables such as surgical electrosurgical units, endoscopes, and puncture instruments. The internal medium blocks discharge to generate plasma + hydrogen peroxide atomization, achieving low-temperature rapid sterilization. Airtight protection: The cavity is sealed with a rubber ring, preventing the leakage of harmful gases during the sterilization process and protecting medical personnel inside the tent; Door electromagnetic interlock device 402: Safety forced interlock: The door is automatically locked in the event of a power outage, and cannot be opened during the sterilization process or when the level of harmful gases in the cavity exceeds the standard, to prevent ozone and hydrogen peroxide gas leakage from causing injury; Linkage sensor logic: Linked with ozone and hydrogen peroxide sensor 403 signals, the electromagnet will only unlock the door and open it if the ozone concentration in the cavity remains below 0.1ppm for 30 seconds, and a simultaneous sound and light warning will be given for safety. Ozone and hydrogen peroxide sensor 403: Real-time monitoring of harmful gases inside the chamber: Continuously monitors the residual concentration of ozone and hydrogen peroxide inside the sterilization chamber, and uploads the data to the central terminal in real time. Safety threshold determination effect: When the concentration is >0.1ppm, an alarm signal is sent to the main controller to maintain the door lock; after the threshold is reached, the unlocking process is triggered, which is the core of the interlocking mechanism. Catalytic decomposition self-cleaning box 404: Harmful waste gas treatment: After sterilization, the circulating fan forces the gas in the cavity to flow through the catalytic box, catalytically decomposing ozone and residual hydrogen peroxide. Hydrogen peroxide decomposes into water and oxygen; Ozone is reduced to oxygen. Safety and emission performance: After decomposition, harmless air is discharged from the cabin. Its use in a sealed field tent will not cause respiratory damage to medical personnel and there is no secondary pollution.

[0073] like Figure 7 As shown, the working process of the portable sterilizer is as follows: Sterilization stage: Inject hydrogen peroxide atomized liquid, and generate plasma through dielectric barrier discharge for 10 minutes.

[0074] Residue removal stage: Sterilization ends, and the circulating fan starts. The gas is forced through a catalytic box containing manganese dioxide (MnO2) honeycomb ceramic, 2H2O2->2H2O+O2; O3->O2.

[0075] Interlocking logic: The hatch latch is controlled by an electromagnet (power off locking), and an electrochemical ozone sensor is installed inside the cavity.

[0076] If Sensor_Value > 0.1ppm, the MCU outputs a low level, the electromagnet remains locked, and a red warning is displayed on the screen.

[0077] Only when Sensor_Value ≤ 0.1ppm and duration > 30s, the MCU outputs a high level, the electromagnet activates to unlock, the screen displays a green "Door can be opened" message, and the buzzer sounds a short beep.

[0078] Example 7: AR Offline Edge Computing The intelligent auxiliary interaction module 500 includes an edge computing NPU chip 501 and a bone conduction communication component 502; Edge computing NPU chip 501: Local offline AI computing power core: Local storage of lightweight human anatomy neural network models and battlefield wound care databases, without relying on external servers or wireless networks; Real-time surgical field image segmentation: After the binocular camera captures the surgical scene, the identification of blood vessels, organs and bleeding points is completed locally, and AR overlay markers are rendered in milliseconds; Offline mode automatic switching function: When the wireless communication heartbeat packet is lost for more than 500ms, the local NPU is automatically started to perform calculations, and the navigation prompts are not interrupted throughout the process; Bone conduction communication component 502: Tactical silent communication: bone conduction sound transmission, no need to block the ear canal, allowing you to receive commands from teammates and medical guidance from the rear during surgery, without isolating the ambient battlefield sound. Dual-mode communication compatibility: Receives tactical radio signals in wireless mode; transmits voice via fiber optic cable in wired silent mode with no radio frequency leakage, suitable for covert operations; Sterile fit: The outer shell is waterproof and can be wiped and disinfected, and the headband is a replaceable sterile disposable cover, which meets the sterile requirements of the operating room.

[0079] The smart head-mounted module has a built-in high-performance NPU chip.

[0080] Data preparation: Key anatomical structures of the human chest and abdomen (blood vessels, bile ducts, ureters, etc.) are pre-trained into lightweight neural network models and stored in local eMMC memory.

[0081] Offline trigger: When the heartbeat packet of the communication module is detected to be lost, the system automatically loads the local model.

[0082] Workflow: Binocular cameras acquire surgical field images -> NPU performs real-time segmentation and recognition -> identifies bleeding points (high-frequency flashing red) or key channels (semi-transparent green coverage) -> overlays these images onto the surgeon's field of vision via a waveguide lens. This process requires no external network support.

[0083] like Figure 5 As shown, fluid system supporting components P pressure sensor: Real-time acquisition of vacuum level in negative pressure pipeline, monitoring of pressure change rate dP / dt, and identification of pipeline blockage by blood clots or tissue debris.

[0084] Gas-liquid separator: Separates blood, tissue waste fluid and surgical smoke gas in the suction line. The liquid is retained at the rear end of the line, and the gas is sent into the ULPA filter element.

[0085] ULPA ultra-low penetration filter: filters viruses, cells, and carcinogenic aerosols from smoke, allowing clean air to be discharged and protecting the respiratory tract of medical staff.

[0086] VacPump negative pressure vacuum pump: provides continuous negative pressure to complete the suction of surgical field smoke and waste liquid.

[0087] FluidPump: a peristaltic pump that delivers saline solution for normal intraoperative irrigation and pulsed backflushing in case of blockage.

[0088] MCU control logic (anti-clogging and smoke exhaust): The fluid system main control unit receives pressure and smoke sensor signals, automatically adjusts pump speed, and triggers the Auto-Backflush adaptive backwash process.

[0089] Figure 1 The central intelligent control terminal 100 was demonstrated as the core hub, which was connected to the split surgical execution module 200, the minimally invasive visualization and operation module 300, the environmentally adaptable sterilization module 400, and the intelligent auxiliary interaction module 500.

[0091] Figure 1The document specifically demonstrates the "silent mode" logic where the system cuts off the wireless radio frequency signal when a physical cable is connected.

[0096] Figure 3 The mechanical structure of the dual anti-mistouch button was demonstrated, including a high-damping silicone pad and a double-layer spring design (two-stage tactile feedback).

[0097] The location of the optical smoke sensor 213 at the front end of the handheld actuator 210 and the smoking channel are shown.

[0098] Figure 4 The three-dimensional structure of the "stepped Luer locking compatible connector" at the tail of the handheld actuator 210 is shown, with the inner Luer female head taper and the outer three-level pagoda barb structure clearly visible.

[0099] Figure 4 The threaded locking connection between the dedicated sterile tubing and the interface is shown.

[0100] Figure 4 This demonstrates the interference-sealed connection of a universal infusion tubing forcibly fitted into a pagoda-shaped barb in an emergency.

[0101] Figure 5 The connection between the gas-liquid separation in the negative pressure suction circuit and the ULPA filter cartridge 225, the vacuum pump, and the peristaltic pump in the flushing circuit is shown in the form of a block diagram.

[0102] The diagram shows the control logic flow: pressure sensor detects vacuum level -> MCU determines blockage -> triggers flushing pump to reverse / output pulse -> completes adaptive backflushing.

[0103] Figure 6 The demonstration showed the base in "ratchet gripping mode," engaged with the tubular handle of the field stretcher.

[0104] Figure 6The demonstration showed how the base unfolds into a "foldable piercing stake" that can be fixed to soft, muddy ground.

[0105] Figure 6 The demonstration showed that the base uses a "vacuum suction cup" to adhere to the smooth inner wall of a container or armored vehicle.
