Description

Technical Field

[0001] The present invention relates to the technical field of medical devices. More specifically, the present invention relates to a multi-stage filtered air compression adjustable positive pressure air supply system for endoscopic surgery. Background Art

[0002] In the prior art, traditional endoscopic electrocautery devices mainly focus on single electrode cutting and coagulation functions, and have not realized the functional integration of air compression air supply and electrocautery; although some existing surgical air supply devices can achieve air compression and multi-stage filtration, they are mostly used for cavity dilation or one-way purging, without realizing coordinated control with the electrocautery, and do not have the ability to adjust the exhaust pressure in real time dynamically.

[0003] This solution proposes to use the air in the operating room as the source, which is filtered and compressed in multiple stages and then serves the aerodynamic electrocautery at the same time, realizing a dynamic working mode of "cutting - coagulation - air flow cleaning" and synchronously realizing the automatic adjustment of the exhaust pressure; However, in the process of engineering this system, the unique coexistence characteristics of air compression air supply and strong electric field bring new challenges that the prior art has never faced. That is, when high-speed air flow and electric field operate superimposed in the same micro catheter, the air flow shear effect is likely to induce micro charge migration, resulting in the distortion of the electric field spatial distribution, and then causing the instability of the electrocautery working state and the fluctuation of the cutting energy output, which becomes the key technical bottleneck affecting the system coordination stability.

At the same time, an electrical and air flow synchronous control and dynamic feedback adjustment mechanism is introduced to systematically solve the key problems in the prior art such as the separation of the air supply and electrocautery functions, the inability to coordinate control, and the instability of the electrocautery operation caused by air-electric interference.

[0021] It should be noted that in the formula structure involved in this scheme, dimensionless terms can be used as proportional or structural adjustment factors. When combined with quantities with units, they only play a role in numerical scaling and do not introduce new physical dimensions. Therefore, they will not change or confuse the unit system of the overall expression. This combination of "dimensionless terms and unit terms" can be understood as a composite structural expression commonly used in mathematical and physical modeling, which conforms to the principle of dimensional consistency and has a clear physical interpretation basis. Secondly, in the formula structure of this scheme, if multiple variables with different physical units are involved, including but not limited to time, mass or energy variables, their joint appearance is to express the collaborative modeling relationship of multiple physical mechanisms. Each variable can form a unified structure through function mapping, ratio combination or normalization adjustment, with clear units and meanings, and the overall expression conforms to the principle of dimensional consistency and the common formula of engineering modeling; In this solution, if constants, weights, adjustment factors, threshold parameters, proportional coefficients, etc. are designed, they are all adjustable control parameters for different application environments. Their values depend on the target device configuration, data input characteristics and performance optimization goals. They are set within a reasonable range through model verification, performance constraints or engineering calibration during the implementation phase. Although such parameters do not have a unique preset value, they have clear adjustment logic and calculation path, and belong to the deterministic setting process in engineering implementation. The purpose of such setting is to ensure that the solution is both universally adaptable and reproducible and operable, without affecting its technical clarity and feasibility. The air supply and filtration module collects air in the operating room, constructs a multi-dimensional pollution complexity factor, performs an air compression process to regulate the gas state, removes particulate matter, dust, bacteria and viruses through a three-stage filtration process, and outputs sterile air data that meets the cleanliness requirements; Defining the pollution complexity factor It is expressed as: in is the ATP concentration in the air, which indicates the activity level of bacteria and viruses; is the response time of the ATP sensor, which is used to construct the activity ratio; is the particle number density (indicating large particle size, greater than 10 μm); is the average particle size of particulate matter; is the dust number density (representing fine particle sizes, less than or equal to 10 μm); is the average dust particle size; pollution complexity factor is used to measure the comprehensive interference degree of pollution intensity on subsequent compression efficiency and filtration efficiency; Based on the physical state of the gas after the air in the operating room is processed by the air compression unit, a compression state model is established: where is the ambient temperature in the operating room, (unit: degree Celsius); is the ambient humidity in the operating room (unit: %), where temperature and humidity are linearly combined as two dimensionless normalization factors affecting the air state, and are used to construct a control index for compression efficiency, rather than direct physical quantity operations; is the air compression efficiency factor; is the unit pressure of the compressed air; is the density of the compressed air, and the density of the compressed air is used for subsequent filtration efficiency adjustment; in addition, the in the formula is to convert Celsius temperature to thermodynamic absolute temperature unit (Kelvin); Based on the first filtration unit, a particulate matter filtration efficiency model is constructed: Based on the second filtration unit, a dust filtration efficiency model is constructed: Based on the third filtration unit, a bacteria and virus filtration efficiency model is constructed: Finally, the sterile air data is expressed as: where is the particulate matter filtration efficiency; is the dust filtration efficiency; is the bacteria and virus filtration efficiency; represents the sterile air data, and the finally generated sterile air data is transmitted to the aerodynamic electric hook working module to form air input data; in addition the higher the value of, the higher the cleanliness effect of the air after compression and hierarchical filtration under a specific pollution load.

[0022] The aerodynamic electric hook working module uses the sterile air data Taking the air input data, combining with the auxiliary air flow data output by the air flow channel component and the electrode state data of the electric hook electrode component, constructing a heterogeneous state propagation function and introducing an attention mechanism for normalization to generate a synergy index, and finally forming the tissue debris cleaning rate, tissue processing rate and tissue separation effect index as the input basis for the subsequent module; Define as the propagation response intensity of the cooperative state diagram, and model the heterogeneous state propagation function: where is the air flow velocity in the auxiliary air flow data; is the air flow pressure in the auxiliary air flow data; is the electrode current intensity in the electrode state data; is the electrode voltage in the electrode state data; represents the air quality dominant weight factor in the heterogeneous graph state propagation. The air quality dominant weight factor in the heterogeneous graph state propagation is used to adjust the dominant influence of the sterile air data in the graph structure propagation; represents the electrode state adjustment weight factor in the heterogeneous graph state propagation. The electrode state adjustment weight factor in the heterogeneous graph state propagation is used to dynamically regulate the response proportion of the electrode voltage and current in the state propagation; For perform attention normalization regulation: where is the attention mechanism normalization factor.

Therefore, the sublinear power of 0.6 is used to suppress the weight growth; while the tissue processing process depends on the stable output of the electrode and the precise control of the direction, with non-linear enhancement characteristics and continuous heat diffusion effects. Therefore, the superlinear power of 1.4 is used to amplify its weight ratio to conform to the dominant contribution of the processing link to the final separation effect in actual surgery; In addition, as a further solution of the control coefficient includes, but is not limited to: where is the partial derivative symbol, indicating that in a multivariable system, when only one variable changes, its influence on the result; here, represents the change amount of the tissue processing rate brought by each tiny change unit of the synchronous frequency on the premise that other factors remain unchanged.

[0024] It should be noted as a whole that during laparoscopic surgery, tissue separation and debris cleaning are often accompanied by the combined operation of the thermal effect of the electrode and the air impact flow. However, the existing surgical assistance systems generally separate air supply, electrode signals, and tissue reaction processing into isolated units, resulting in practical problems such as unstable air sources, residual debris interfering with the field of view, and asynchronous electrode cutting and cleaning. In response to this technical blind spot, this solution introduces the mode of compressing and multi-stage filtering the air in the operating room at the source, using it as an internal self-sufficient gas source system under the condition of no external gas supply, and using this sterile air as the collaborative input of the pneumatic electric hook system to ensure the unity of safety, continuity, and cleanliness. The air supply and filtration module is used to directly collect air from the operating room and obtain its basic environmental parameter data (temperature, humidity, particulate matter content, dust content, bacterial and viral content, etc.). The air first enters the air compression unit to form compressed air with pressure regulation ability. Subsequently, it undergoes three-stage purification operations through the first filtration unit (removing particulate matter), the second filtration unit (removing dust), and the third filtration unit (removing bacteria and viruses) connected in series in sequence, and finally outputs sterile air data with a cleanliness level meeting the intraoperative requirements. The entire filtration logic is constructed based on the particle size difference distribution, and the filtration path efficiency can be adjusted through the dynamic calculation of the pollution complexity factor to achieve adaptive filtration of the pollution load. After the sterile air data enters the aerodynamic electric hook working module, it is converted into an air dynamic path through the air flow channel component to form an auxiliary air flow with directionality and impact force. At the same time, the electric hook electrode component receives data on the intraoperative electrode state, including current, voltage, and temperature. The two component structures are independent but operate collaboratively. Through the collaborative conduction operation, the air flow and the electrical signal act on the target tissue area synchronously: the former clears tissue debris, and the latter completes tissue cutting or coagulation. The collaborative operation mechanism is constructed on the heterogeneous graph state propagation structure, that is, the air flow data and the electrode data are used as two types of nodes, and through the attention normalization control, the superposition of the two in time and space is achieved to form tissue debris cleaning data and tissue processing data. The electrical and air flow collaborative monitoring module is used to perform multi-dimensional deconstruction and stability evaluation on the collaborative action data formed in the aerodynamic electric hook working module. The input data is parsed into air flow parameters and current parameters, and the interaction relationship data is constructed through joint analysis. This relationship data is used to determine whether the current system is in a stable collaborative state: if it is stable, the current state is maintained; if it is unstable, the abnormal intensity data is output, triggering the compensation and correction process of the abnormal compensation and collaborative stability module. After the abnormal compensation and collaborative stability module receives the abnormal intensity data, the system will generate target compensation parameters based on comprehensive factors such as air flow disturbance, electrical signal fluctuation, and collaborative deviation; the set of target compensation parameters includes the target magnetic flux density, compensation duration, and compensation application position for electromagnetic control or air flow adjustment; determine whether the compensation parameters are within the safety threshold, and if not, return for re-correction; after the compensation is applied, the system will record the application result and perform the collaborative state judgment again to ensure the stability and real-time adjustment ability of the surgical process; In this solution, the entire system is constructed based on the collaborative mechanism of air and electrode dual channels, the state fusion graph propagation mechanism, the dynamic stability evaluation, and the self-closed-loop compensation mechanism; by compressing and triple-purifying the air in the operating room to form a reliable air source, positive pressure air supply is realized without relying on external equipment; by converting the air input and electrical signals into the states of heterogeneous nodes in the graph structure, and using the state propagation and attention mechanism to superimpose and model, a collaborative effect index is constructed to achieve synchronous action on the target tissue; at the same time, the system introduces an air-electricity monitoring feedback path, and automatically triggers the generation and application of compensation signals when tissue response abnormalities or air-electricity offsets occur, and finally realizes the collaborative control and intervention of air, heat, and electricity during the operation.
