[0002] The continuous improvement of living standards and the intertwined influence of factors, such as viral invasions in the living environment, have posed varying threats to the health of the human body and most biological species. Of course, there are also physiological changes that occur with aging, causing tissue hyperplasia and cysts within the tissues of certain organs that can affect organ function or cause severe pain, often requiring open surgery to remove and suture the wound. However, surgical procedures carry significant risks, and wound healing and tissue recovery take a long time, which also creates challenges in nutritional supplementation, such as overdoing it, avoiding the important and focusing on the minor, and requiring dietary restrictions.

[0003] Other research on this type of tissue lesion and hyperplasia has explored the potential for minimally invasive surgery, combined with mechanical excision, laser enucleation, microrobot excision, or high-temperature steam ablation. However, the appropriate instrument selection must be carefully considered, taking into account cost, surgical risk, and postoperative healing outcomes.

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a schematic diagram of the assembly structure of a preferred embodiment of the adaptive intelligent steam ablation device of the present invention. DETAILED DESCRIPTION

[0016] The specific implementation methods of the present invention will be further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp, thereby making a clearer definition of the protection scope of the present invention.

[0017] In view of the objective deficiencies in some treatment methods for abnormal proliferation of biological tissues, the designers of the present invention have innovatively proposed an intelligent water vapor ablation device, which uses dynamic steam pressure monitoring and autonomous learning to adjust steam delivery volume and temperature to perform minimally invasive ablation, local heating and pipeline dredging on biological tissues.

[0018] like Figure 1 As shown, the adaptive intelligent steam ablation device consists primarily of three components: a thermal ablation controller 1, a steam generator 2, and an operator 3. The operator features a gun-like handle 31 with a trigger 32 and a steam delivery tube 33 extending therethrough. The gun-like handle 31 is equipped with a puncture device 34 with an insulated outer tube at its muzzle. The steam delivery tube 33, which extends through an insulated outer tube 341 and is equipped with one or more steam ejection holes 3311, flexibly bends within a side hole 342 at the distal end of the insulated outer tube and is driven to extend and retract by the trigger 32. The tip of the steam delivery tube (which can be referred to as the ablation needle) is made of a thin tubular material with memory properties (such as nickel-titanium alloy) and can be inserted and withdrawn from the side hole into the tissue to be ablated. The side hole's opening direction, angle range, and concave inner wall are designed to guide the ablation needle. During the extension of the ablation needle, the angle can be adjusted within a range of 0 to 90 degrees as the needle is pushed forward. The steam generator 2 and the thermal melt controller 1 are integrated into the main unit. The steam generator 2 is connected to the steam delivery tube 33 in the operator via a pressure-resistant steam hose 4 and its quick-connect interface. The thermal melt controller 1 includes an MCU that interfaces with the operator via bus 5 signals and uses this MCU to control the steam generator and adjust steam output. A needle valve 35 is installed on the steam delivery tube in the operator. This needle valve is controlled by the MCU through manual adjustment or bus connection, allowing the steam pressure delivered to the steam delivery tube to be adjusted from zero to the desired level for tissue ablation.

[0019] The above-mentioned MCU has a built-in AI full-angle ablation module and communicates with an external AI server. There are multiple communication methods as long as the data transmission rate is met. The AI ​​server integrates a variety of currently available AI software. It compares the preset technical parameters with the dynamic steam pressure, dynamic steam flow and its change rate obtained from the operator during the tissue ablation process over time, and controls the steam generator through the MCU signal to adjust the steam output to obtain the steam temperature and delivery volume with the best tissue ablation speed and effect. Because the steam pressure is relatively high before tissue ablation in the process of puncturing tissue and spraying high-temperature steam to ablate it, and the steam pressure will fluctuate downward rapidly after the tissue is decomposed and ablated, it is necessary to timely reduce the steam delivery volume in the steam transmission tube to avoid excessive steam injection; and when the ablation needle position is changed to touch the new tissue that needs to be ablated, the sudden increase in steam pressure requires timely increasing the steam delivery volume in the steam transmission tube to maintain the ablation operation. The AI ​​software version can utilize a combination such as STM32Cube.AI and NanoEdge AI Studio, which provides a full-link solution combining hardware acceleration, small data AI, and clinical adaptation. This solution not only meets the stringent real-time and security requirements of medical devices, but also lowers the barrier to entry for AI development, enabling the rapid launch of intelligent, precise, and high-end medical devices. Furthermore, the AI ​​server acquires and stores steam-related parameters from the previous tissue ablation process, providing a reference for data comparison and analysis for subsequent tissue ablations.

[0020] From a functional perspective, the steam transmission tube in the operator's control panel is equipped with a sterile filter 36 and sensors for measuring steam temperature and pressure (not shown). This not only enhances the sterility and safety of the delivered steam, but also connects the signal feeders of these sensors to the bus 5 and transmits them to the MCU. The steam generator includes a water tank 21 for storing water for injection and an evaporator 22. The evaporator is equipped with a pressure controller, which is controlled by the MCU to maintain steam output within a set pressure range, thereby maintaining a stable steam source. This is a mature device with a wide range of options, except for differences in volume and steam flow rate. The puncture device is primarily inserted into the proliferating area of ​​biological tissue, either directly or minimally invasively, to the desired location. It serves as a carrier for the steam transmission tube, allowing the steam jet to locate the end point for the ablation operation. The steam transmission tube itself is a flexible, relatively rigid tube with a spike-shaped end that can be further inserted into the proliferating tissue. The steam perforations are formed around this tip. Among them, the thermal melt controller adds monitoring of steam pressure, flow and temperature during tissue ablation, and on this basis participates in extended AI software engineering through the AI ​​full-angle ablation module integrated with MCU, thereby optimizing the pressure, flow and temperature of steam ejected from the steam perforations, so that tissue ablation can reach the speed and results required by clinical practice. Here, the steam generator is usually large in size and occupies a large area. It is a fixed floor-standing setting. The thermal melt controller is integrated with it and can be repeatedly used statically for a long time. The operator is a handheld device that is customized in batches and disposable. The two parts are connected to the steam operation channel through a pressure-resistant steam hose and a quick coupling interface. The pressure-resistant steam hose mainly refers to a hose that can be bent and shaped, and the distance and direction of the pipeline wiring can be adjusted. The layered organizational structure includes an internal metal bellows, a middle-layer insulation layer sleeve and an outer wall wear-resistant fiber protective layer.

[0021] The operator is a relatively small handheld device, and the puncture device is integrally mounted therewith, and they are linked as a whole during ablation operations. The puncture device has the functions of a heat-insulating outer tube that can rotate with the gun-type handle and a steam transmission tube that can be retracted and extended, so that the steam injection point can be adjusted by micro-operation. In particular, the steam transmission tube also has axial displacement adjustability relative to the heat-insulating outer tube. Specifically, the trigger is pivotally connected to the gun-type handle, and the upward extension section of the trigger is provided with a ring facing the steam transmission tube, so that with the slight rotation of the trigger, the ablation needle can be linked to advance and retreat in the heat-insulating outer tube and its side hole, so that the ablation needle passes through the side hole in a 0-90 degree bend and enters the tissue to be ablated. After the local ablation is completed, it retreats backward, so that the spike is retracted into the side hole to facilitate the puncture activity of the heat-insulating outer tube and avoid additional cuts.

[0022] Looking at further details, the gun-style handle 31 is equipped with a condensation drain pipe 37, and the puncture device is connected to the condensation drain pipe through the side hole of the insulated outer tube. This allows the steam and water condensed and liquefied during the tissue ablation process to be discharged through this channel. The outer wall of the insulated outer tube is also equipped with a direct-view scale 343 to indicate the depth of the needle tip into the tissue. The hot melt controller 1 is also equipped with a pressure gauge, temperature gauge, and flow meter, which use bus feedback signals to visually display the dynamic steam pressure, steam flow, and its rate of change in the steam transmission tube.

[0023] Furthermore, considering that tissue ablation is a dynamic process, the steam jet direction is not fixed and needs to be adjusted as the ablation progresses. Therefore, the heat-insulating outer tube is rigidly connected to the gun-style handle, and the operator manually adjusts the angle by changing the gun-style handle clockwise or counterclockwise along the axis of the heat-insulating outer tube, allowing the ablation needle to extend and penetrate the tissue to be ablated as needed in the circumferential direction.

[0024] From the above introduction to the scheme and detailed description of the embodiments of the adaptive intelligent steam ablation device of the present invention, it can be seen that this scheme has outstanding substantial characteristics and significant progress, and its technical effects are manifested as follows: the device optimizes the structure of the operator and its function realization, and the thermal melt controller integrates the MCU communication interconnection AI server, and has the ability to autonomously learn the pressure state changes in the thermal melt controller and the degree of ablation of the surrounding tissue. The thermal melt controller can continuously correct the steam delivery volume and the changes in temperature and pressure according to the working pressure required for ablation of proliferative tissue, so that the working pressure is maintained in the optimal range to optimize the ablation process, thereby improving the efficiency of the ablation operation and the convenience of operation. From an implementation cost perspective: the steam generator and thermal melt controller in the present invention are medium-sized devices that occupy a certain amount of space, while the operator is a small, handheld device that typically needs to meet strict surgical instrument hygiene standards. Therefore, the operator can be designed as an integrated device, where the needle valve and sensor on the steam transmission tube are disposable and disposable. However, in some implementations, the needle valve and sensor are relatively expensive, making reuse more cost-effective than single-use. Therefore, the operator can also be designed as a modular assembly, where the needle valve and sensor are independent modules that are assembled into a gun-type handle through an interface and functionally contact the steam transmission tube. Specifically, the needle valve body is positioned and attached to the gun-type handle via a snap-fit ​​structure, and the needle valve clamp is sleeved onto the outer wall of the steam transmission tube to control the steam flow rate in the tube.

[0025] In addition to the above embodiments, the present invention may also have other implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
