Description
Technical Field

[0002] The intelligent electrosurgical knife is a high-frequency electrosurgical knife with an intelligent monitoring system. The high-frequency electrosurgical knife is an electrosurgical instrument that replaces the mechanical scalpel for tissue cutting. It sends high-frequency current into the human body through electrodes (to form high-density current in the local tissue under the electrosurgical pen, thereby promoting local high heat generation, thereby achieving two electrosurgical effects of cutting and coagulation. When using the intelligent electrosurgical knife, the operator only needs to clamp the tissue firmly with a closing device. After starting the output, the system will automatically and continuously output high-frequency energy until the closure is completed as the impedance of the soft tissue changes. The operator does not need to manually control the energy output and stop, thereby reducing thermal damage during the operation and improving the quality of the operation and the strength of the soft tissue welding anastomosis.

[0055] The present invention is further explained and illustrated below in conjunction with the accompanying drawings and specific embodiments of the specification. The step numbers in the embodiments of the present invention are only provided for the convenience of explanation and description, and no limitation is imposed on the order of the steps. The execution order of the steps in the embodiments can be adaptively adjusted according to the understanding of those skilled in the art.
[0056] like Figure 1 As shown, this embodiment provides a test device for the performance of an intelligent electric knife, including a (biological soft tissue) impedance simulator and an electric knife analyzer (not shown). The bipolar electrode of the welding tool on the (high-frequency) intelligent electric knife (not shown) is connected to the impedance simulator, and the electric knife analyzer is connected to any electrode of the welding tool of the intelligent electric knife and the impedance simulator. The biological soft tissue impedance simulator is used to simulate the impedance change of biological soft tissue, and in this embodiment includes a controller (not shown), a stepper motor 1, a linear moving platform (including a ball screw 2 and a moving table 3 that can move on the ball screw), wherein the moving table includes a contact block for conducting the electrode of the non-inductive resistor, and a non-inductive resistor array (including a plurality of non-inductive resistors 4 connected in series).
[0057] In this embodiment, the controller can process data and control the resistance value of the non-inductive resistor in the access circuit by programming and controlling the rotation of the stepper motor to guide the movement of the motion stage (different motion stage positions), so as to realize the change of the impedance of the non-inductive resistor array, which is equivalent to a variable resistor to simulate the soft tissue impedance. Optionally, in this embodiment, the controller can program and control the stepper motor to control the movement distance of the motion stage to realize the simulation of the change of soft tissue impedance. The controller can be a computer, and can further store a preset welding model (biological welding mathematical model).
[0058] In this embodiment, the non-inductive resistor array includes a plurality of non-inductive resistors, and the inductive reactance of the non-inductive resistor is small, which can prevent oscillation in high-frequency equipment, such as high-frequency intelligent electric knife, and reduce the output power deviation and high-frequency resonant voltage. Therefore, the impedance simulation device has the characteristics of no inductive reactance, good heat dissipation and anti-oscillation. In this embodiment, the non-inductive resistor uses RIG type high-power non-inductive glaze film resistor, in which a high-frequency porcelain tube with an aluminum content of more than 95% is used as the resistor matrix, and a coating made of high-voltage insulating heat dissipation paint is applied after air drying and high-temperature baking, which has the characteristics of strong overload capacity, high temperature characteristics, excellent insulation, good heat dissipation, etc.
[0059] The intelligent electrosurgical knife is connected to an impedance simulation device and can adjust its output current and voltage according to the change of the impedance of the non-inductive resistor array. The electrosurgical knife analyzer can obtain the dynamic real-time power output curve of the intelligent electrosurgical knife according to the change of current and voltage.
[0060] In this embodiment, the dynamic real-time power output curve of the intelligent electric knife is compared with the preset welding model to obtain the test result.
[0061] like Figure 2 As shown, this embodiment also provides another device for testing the performance of an intelligent electric knife, including: a first acquisition module, used to acquire a preset welding model, wherein the preset welding model includes a first relationship between a first resistance value and a time change, and a relationship curve between a voltage and a time change;
[0062] A second acquisition module, used for acquiring a position of the moving platform corresponding to the first resistance value according to the first resistance value;
[0063] A simulation module, used for simulating a first resistance value by connecting a plurality of non-inductive resistors according to the position of the motion platform;
[0064] The third acquisition module is used to obtain the parameters corresponding to the intelligent electric knife according to the simulation results;
[0065] A test module, used to obtain test results according to a preset welding model and the parameters;
[0066] The position of the moving platform includes the position of the moving platform that is movable when a plurality of non-inductive resistors are connected and turned on, and the parameters include voltage.
[0067] The contents of the above-mentioned device embodiments are all applicable to the present device embodiments. The functions specifically implemented by the present device embodiments are the same as those of the above-mentioned device embodiments, and the beneficial effects achieved are also the same as those achieved by the above-mentioned device embodiments.
[0068] like Figure 3 As shown, this embodiment also provides a method for testing the performance of an intelligent electric knife, comprising the following steps:
[0069] Acquire a preset welding model, wherein the preset welding model includes a first relationship between a first resistance value and a time change, and a relationship curve between a voltage and a time change;
[0070] According to the first resistance value, obtaining a position of the moving platform corresponding to the first resistance value;
[0071] According to the position of the motion platform, a first resistance value is simulated by connecting a plurality of non-inductive resistors;
[0072] According to the simulation results, the corresponding parameters of the intelligent electric knife are obtained;
[0073] According to the preset welding model and the parameters, a test result is obtained;
[0074] The position of the moving platform includes the position of the moving platform that is movable when a plurality of non-inductive resistors are connected and turned on, and the parameters include voltage.
[0075] In this embodiment, the reason for obtaining a preset welding model is that high-frequency current has a series of physiological effects on biological soft tissues, including electrical stimulation, thermal effect, reversible electroporation of cell membranes, etc., and high-frequency electric knives mainly use the thermal effect of high-frequency current and the reversible electroporation effect of cell membranes to prevent electrical stimulation. Therefore, in order to achieve reliable soft tissue welding and separation, it is necessary to ensure that the temperature of the welding process is controlled within the reversible thermal denaturation range of the protein based on the biological welding theory. Therefore, it is necessary to obtain a preset welding model, which is obtained through comprehensive analysis from aspects such as tissue pathology, comparison of surgical effects of similar equipment, and in vitro and in vivo experiments on soft tissues of animals. It reveals that when the soft tissue of an organism is subjected to thermal stimulation, a voltage U of a specific curve is applied to the soft tissue, and the tissue impedance Z between the two poles of the welding tool of the intelligent electric knife shows a regular change (curve), such as Figure 4 As shown, a voltage U with a specific curve is applied to the soft tissue, and the current passes through the soft tissue and heats it. The intercellular fluid has a positive temperature coefficient of conductivity, so as the tissue is heated, the impedance Z decreases and reaches its minimum value Z at time t1. min . Subsequently, the welding tissue begins to solidify, resulting in an increase in impedance. When the set value ΔZ (time t2) is reached, it begins to enter the stable stage. At this time, regardless of the thickness and physical properties of the welding tissue, the temperature of the tissue will not rise. When the time reaches t3, the tissue bonding strength is large enough and the energy transfer stops. Among them, the impedance includes a first resistance value, that is, the preset welding model (biological welding mathematical model) includes the relationship between time, voltage and the first resistance value, wherein the relationship between time, voltage and the first resistance value includes a change curve of the first resistance value corresponding to the change of voltage, and may also include other curves that can reflect the relationship between voltage and the first resistance value by converting the relationship between voltage and the first resistance value, such as an output power curve, etc. In this embodiment, the relationship between voltage and the first resistance value is the change curve of the first resistance value Z corresponding to the specific change curve of voltage U. Among them, the first resistance value includes a resistance value that is an integer multiple of the resistance value of a single non-inductive resistor.
[0076] In this embodiment, according to the first resistance value, the position of the moving platform corresponding to the first resistance value is obtained, and according to the position of the moving platform, the step of simulating the first resistance value by connecting a plurality of non-inductive resistors specifically includes:
[0077] S1. Reconstruct a preset welding model, divide the reconstruction result according to the first resistance value and perform discretization processing.
[0078] like Figure 5 As shown in the figure, since the resistance value in the preset welding model changes continuously, and the impedance simulation device is composed of several non-inductive resistors with fixed resistance values connected in series, the resistance change curve in the preset welding model can only be processed by step discretization, and further discretized by computer to obtain the coordinate data point set of time and resistance value after discretization (t i , z i ), that is, the law of the change of the first resistance value with time, where z i is the first resistance, i.e., an integer multiple of the resistance z0 of a single non-inductive resistor;
[0079] S2. According to the first resistance value, obtain a position of the moving platform corresponding to the first resistance value.
[0080] like Figure 6 As shown, specifically: through the movement of the moving stage, a number of non-inductive resistors are connected and turned on to obtain all first resistance values, and the position of the moving stage at this time is recorded respectively, wherein x represents the moving distance of the moving stage.
[0081] S3, according to the rule and the position of the motion table, simulate the first resistance value. Specifically including:
[0082] S31, according to the rule and the position of the motion platform, obtain a number of position data, wherein each position data includes the position and time of the motion platform;
[0083] Generate an image. The relationship between the position of the moving table on the impedance simulation device and the change of resistance is a step diagram. Set the end point as the transformation point, and then transform the resistance data of the preset welding model after discrete transformation into position data, that is, (t i , z i ) conversion (t i , x i ), (t i , x i ) is the position data, where x i is the position of the motion platform, t i For time.
[0084] S31. Filter each location data according to the time and the preset change time.
[0085] Specifically: obtaining a first time of first position data and a first difference between a second time of second position data adjacent to the first position data;
[0086] When the first difference is greater than or equal to the preset change time, the second time is changed to the difference between the second time and the preset change time, and the changed second position data is used as the new first position data, and the step of returning to obtain the first time of the first position data and the first difference of the second time of the second position data adjacent to the first position data is returned until the first time is the smallest time in the position data;
[0087] When the first difference is less than the preset change time, the second position data is excluded, the second time of the second position data adjacent to the first time of the first position data is re-acquired, and the step of returning to the step of acquiring the first time of the first position data and the first difference of the second time of the second position data adjacent to the first position data is returned until the first time is the smallest time in the position data;
[0088] The first time is the maximum time, the second time is the time adjacent to the first time, and the position data includes the first position data and the second position data. The time for the mobile station to complete an impedance change at a speed v is set to t0, that is, the moving time between two (adjacent) non-inductive resistors (preset change time), wherein the speed v can be set according to demand.
[0089] For example, the position data are A(20, 200), B(15, 150), C(10, 100), and D(5, 50), then A is the first position data, B is the second position data, and the first difference is 5. If t0 is 4, B is changed to (11, 150), and then B(11, 150) is used as the new first position data. At this time, the adjacent second position data is C(10, 100). Continue with the above processing method until the first time is the smallest time in the position data, that is, D(5, 50) is the new first position data.
[0090] If t0 is 6 and the first difference is 5, then B is excluded. At this time, the adjacent second position data reacquired is C(10, 100), and the first difference is 10, so C is changed to C(4, 100) as the new first position data, and the above steps are repeated. Similarly, the first time in the new first position data is the minimum time in the position data. Then the screening result is obtained.
[0091] S32. Obtain the moving position of the motion platform according to the screening result.
[0092] The moving position refers to the actual moving position coordinates of the stepper motor, that is, the actual moving position of the final motion platform.
[0093] S33, by moving the moving platform at the moving position, simulate and obtain the first resistance value corresponding to each moving position.
[0094] Through programming, the controller controls the moving platform to move at the moving position, thereby simulating and obtaining the first resistance value corresponding to each moving position of the moving platform, which is equivalent to making the electrode of the intelligent electric knife have the first resistance value.
[0095] S4. According to the simulation results, the corresponding parameters of the intelligent electric knife are obtained.
[0096] The electrode of the intelligent electric knife welding tool is connected to the impedance simulation device, and the electric knife analyzer is connected to the intelligent electric knife. The electrode has a simulated first resistance value. At this time, the electric knife analyzer obtains the current, voltage and output power of the intelligent electric knife at each first resistance value, which is equivalent to simulating the change of the first resistance value through the impedance simulation device, and in turn testing the connected current / voltage change. Then, the dynamic and real-time output power can be calculated through the current / voltage and impedance, and compared with the preset welding model to judge the similarity, so as to detect whether the intelligent electric knife can intelligently adjust the power output according to the impedance change.
[0097] Specifically: the parameters and the relationship curves between the voltage and the first resistance are compared, and optionally, the parameters also include current and output power; the parameters and the relationship curves between the voltage and the first resistance are compared to obtain similarity, wherein the similarity and the corresponding test results include: 1) the relationship curve and the parameter are roughly the same, and the test result is that the intelligent electric knife has an intelligent output adjustment function; 2) if the line type of the parameter is roughly the same as the line type of the relationship curve, but the value is different, the test result is that the intelligent electric knife has a certain intelligent output adjustment function, but the output power is still not optimal; 3) if the line type and value of the parameter are different, the test result is that the intelligent electric knife does not have an intelligent output function.
[0098] Among them, the similarity comparison can also be carried out by first obtaining the corresponding power curve of the first resistance and voltage according to the preset welding model, and comparing the power curve with the curve composed of the output power in the parameters, thereby obtaining the test result.
[0099] Among them, the similarity between the relationship curve and the parameter, the similarity of the line type, and the degree of difference in the numerical values can all be judged by, for example, setting a threshold. In other embodiments, they can also be judged manually, or by combining manual and computer methods to obtain test results, without limitation.
