TECHNICAL FIELD
[0001] The present application relates to the technical field of vascular interventional surgery, and in particular to an interventional robot sheath abnormal state early warning method and device, computer equipment and a storage medium. BACKGROUND
[0002] Vascular interventional surgery is a treatment method for treating intravascular pathogen of a patient by means of surgical equipment. When treatment is performed, an operator in a compartment needs to control the surgical equipment to enter the intravascular pathogen for treatment.
[0003] During the operation of the interventional surgery robot, the connection state between the sheath used for puncture and the driving mechanism needs to be monitored in real time to ensure the safety and reliability of the operation. However, the operation environment is complex, and there are various electromagnetic interference sources such as high-frequency electrotome, nuclear magnetic resonance and other equipment. These interference sources will have a serious impact on the connection state monitoring system, resulting in distorted and inaccurate monitoring data, and even false positives or false negatives. At the same time, the connection structure between the sheath and the driving mechanism is complex, and there are multiple connection points and transmission components. How to achieve reliable connection state monitoring in a complex structure is also a big problem. For example, the following problems may occur due to accidental operation in actual application:
[0004] (1) The vascular sheath and the robot may fall off during the operation, and the operation cannot continue, but the doctor in the compartment cannot see it;
[0005] (2) During the operation, the angle between the vascular sheath and the patient's body is too large due to the patient's movement, or the sheath connector is bent, resulting in increased resistance to catheter delivery. If the delivery continues, the catheter will be damaged, affecting the normal operation;
[0006] (3) After the operation, the sheath and the robot are not separated according to the normal process, and the drive is moved, causing the sheath to be accidentally pulled out of the body, causing bleeding and causing harm to the patient;
[0007] Therefore, it is urgent to design a safety state detection device for the sheath connector of the interventional robot to determine whether the sheath is detached, whether the sheath connector is bent or twisted, etc. In addition, the interventional surgery robot requires high operation precision and good stability. The connection state monitoring system needs to be synchronized in real time with the robot control system, and the robot motion parameters need to be adjusted in time according to the monitoring data, which puts higher requirements on the real-time performance and reliability of the monitoring system.

It is expressly understood that the embodiments described herein are merely examples from a much larger number of embodiments that can be claimed.
[0054] In order to enable persons skilled in the art to better understand the scheme of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings.
[0055] Reference Figure 1 , shows a flowchart of one embodiment of an intervention robot sheath abnormal state early warning method according to the present application. The intervention robot sheath abnormal state early warning method comprises the following steps:
[0056] Step S10, identifying whether the current detection category of the system is the sheath in position detection or the sheath state detection;
[0057] In the embodiment, the sheath in position detection is performed during the operation process and the machine position adjustment process, and the sheath state detection is performed during the operation process. The sheath in position detection is used to detect whether the sheath in the machine is at a preset connection position, which refers to the position where the sheath and the mounting slot are connected and fixed. The sheath in position detection is used to detect whether the sheath is fixed in the mounting slot. The sheath state detection refers to detecting whether the sheath connector currently deforms. When the sheath connector is extruded or stretched by external force and deforms, the sheath state detection detects the change to form the state detection of the sheath connector.
[0058] Step S20, if the current detection category of the system is the sheath in position detection, determining whether the interventional robot is in an operation process state or a position adjustment state;
[0059] In the embodiment, the operation process state refers to the state of the machine working in the interventional operation, and the position adjustment state refers to the state of the machine pausing the operation and adjusting the position of the machine mechanical arm. In the embodiment, the machine mechanical arm is connected with a driver, and the position of the driver and the device connected therewith is adjusted by adjusting the position of the machine mechanical arm.
[0060] Step S30, if the interventional robot is in the operation process state, obtaining a switch level signal from a first monitoring device, identifying the voltage characteristic of the switch level signal, and generating corresponding sheath in position judgment information according to the identification result and sending the sheath in position judgment information to a preset display interface for prompting;
[0061] In the embodiment, the first monitoring device is installed at the position where the sheath and the mounting slot are connected. When the sheath is installed in the mounting slot, the sheath presses on the first monitoring device, so that the state of the first monitoring device changes to output a corresponding switch level signal. The voltage characteristic of the switch level signal corresponds to a high level and a low level. In the embodiment, the corresponding sheath in position judgment information is generated according to the case that the switch level signal belongs to the high level and the low level, and the sheath in position judgment information is displayed on the preset display interface for prompting. The preset display interface refers to the display interface of the system, which can be the display interface of the control terminal connected with the machine. The first monitoring device can be determined through a monitoring object list, which refers to the information list of the device objects that need to be monitored and is pre-stored in the interventional robot. The monitoring object list records a plurality of current monitoring object numbers or names, which can be queried and extracted from the database through a query field. The corresponding first monitoring device is determined from the monitoring object list through a first monitoring object identifier.
[0062] In step S40, if the interventional robot is in the position adjustment state, a switch level signal is acquired from the first monitoring device, voltage characteristics of the switch level signal are identified, and corresponding adjustment state information is generated according to the identification result and sent to the preset display interface for prompting.
[0063] In this embodiment, the voltage characteristics of the switch level signal correspond to high level and low level, and corresponding adjustment state information is generated according to whether the switch level signal belongs to high level or low level, and the adjustment state information is displayed on the preset display interface for prompting. The preset display interface refers to the display interface of the system, and can be the display interface of the control terminal connected to the machine.
[0064] In step S50, if the current detection category of the system is the sheath state detection, a real-time voltage signal is acquired from the second monitoring device, and sheath deformation is judged according to the voltage value of the real-time voltage signal and a preset deformation threshold, and corresponding sheath deformation state information is generated according to the judgment result and sent to the preset display interface for prompting.
[0065] In this embodiment, the real-time voltage signal refers to the voltage signal output at the current time when the resistance value of the second monitoring device changes due to external force. The real-time voltage signal changes in real time with the change of the resistance of the second monitoring device, and is used to monitor the dynamic response of the second monitoring device. Since the voltage value of the real-time voltage signal is proportional to the deformation degree of the second monitoring device, the preset deformation threshold representing the deformation degree of the second monitoring device is set to judge whether the deformation degree of the second monitoring device reaches the preset deformation bearing value. According to the judgment result, corresponding sheath deformation state information is generated, and the sheath deformation state information is displayed on the preset display interface for prompting. The second monitoring device can be determined by a monitoring object list, which refers to a pre-stored information list of device objects to be monitored in the interventional robot. The monitoring object list records a plurality of object numbers or names of the current monitoring, and the monitoring object list can be queried and extracted from the database by checking the query field. The corresponding second monitoring device is determined from the monitoring object list by the second monitoring object identifier.
[0066] The application identifies whether the current detection category of the system is sheath in-place detection or sheath state detection; if the current detection category of the system is the sheath in-place detection, it is judged whether the interventional robot is in a surgical process state or a position adjustment state; if the interventional robot is in the surgical process state, a switching level signal is acquired from a first monitoring device, and the voltage characteristic of the switching level signal is identified, and corresponding sheath in-place judgment information is generated according to the identification result and sent to a preset display interface for prompting; if the interventional robot is in the position adjustment state, a switching level signal is acquired from a first monitoring device, and the voltage characteristic of the switching level signal is identified, and corresponding adjustment state information is generated according to the identification result and sent to the preset display interface for prompting; if the current detection category of the system is the sheath state detection, a real-time voltage signal is acquired from a second monitoring device, and sheath deformation is judged according to the voltage value of the real-time voltage signal and a preset deformation threshold, and corresponding sheath deformation state information is generated according to the judgment result and sent to the preset display interface for prompting. Thus, effective abnormal state monitoring and early warning can be realized during the operation of the interventional robot, so as to ensure the safety and effectiveness of the operation process of the interventional robot.
[0067] With reference to the foregoing description of the method of the application, the method of the application can be implemented by means of a computer program product, which comprises computer program code means adapted to perform the steps of the method of the application when said program is run on a computer. Figure 2 With reference to the foregoing description of the method of the application, the method of the application can be implemented by means of a computer program product, which comprises computer program code means adapted to perform the steps of the method of the application when said program is run on a computer.
[0068] Step S301: identifying whether the switching level signal is high or low.
[0069] In this embodiment, when the switching level signal is acquired, the switching level signal can be preprocessed by the mean filtering method to obtain a standard effective switching level signal. When the sheath is installed in the installation card slot, the sheath will press on the first monitoring device, so that the first monitoring device will output a low switching level signal. When the sheath falls off from the installation card slot, the first monitoring device will recover from the pressed state to the unpressed state, at which time the first monitoring device will output a high switching level signal. The level represents the logarithm of the ratio of the voltage of a certain point in the circuit to a certain reference voltage. Whether the switching level signal is high or low can be judged by identifying the logic level of the output, for example, when the logic level of the switching level signal is 1, the switching level signal is high, and when the logic level of the switching level signal is 0, the switching level signal is low.
[0070] Step S302: if the switching level signal is high, generating sheath falling-off alarm information and sending it to the preset display interface for alarm and prompting.
[0071] In the embodiment, the sheath shedding alarm information includes a preset alarm field, which can be set as a text field for describing the state of the sheath shedding, for example, "Please note! The sheath of the current machine has been shed", and the alarm field can be adjusted according to actual conditions. When the sheath shedding alarm information is generated, the sheath shedding alarm information can be sent to the preset display interface through a preset information sending path and displayed and reminded on the preset display interface.
[0072] In step S303, if the switch level signal is the low level, the sheath in position state information is generated and sent to the preset display interface for display and reminding.
[0073] In the embodiment, the sheath in position state information includes a preset display field, which can be set as a text field for describing the state of the sheath in the preset position, for example, "The sheath of the current machine is in position", and the display field can be adjusted according to actual conditions. When the sheath in position state information is generated, the sheath in position state information can be sent to the preset display interface through a preset information sending path and displayed and reminded on the preset display interface.
[0074] The embodiment identifies whether the switch level signal is a high level or a low level, generates the sheath shedding alarm information and sends it to the preset display interface for alarm reminding if the switch level signal is the high level, and generates the sheath in position state information and sends it to the preset display interface for display reminding if the switch level signal is the low level. Thus, the corresponding sheath shedding alarm information and sheath in position state information can be generated and displayed and reminded according to the high level or low level of the switch level signal when the machine is in the surgical process state.
[0075] With reference to Figure 3 , a flow chart of one specific embodiment of step S40 is shown, including the following steps:
[0076] S401, identifying whether the switch level signal is a high level or a low level;
[0077] In the embodiment, the level represents the logarithm of the ratio of the voltage of a certain point in the circuit to a certain reference voltage, and the switch level signal can be identified as a high level or a low level by identifying the output logic level, for example, when the logic level of the switch level signal is 1, the switch level signal is a high level, and when the logic level of the switch level signal is 0, the switch level signal is a low level.
[0078] S402, if the switch level signal is the high level, generating the robot adjustable information and sending it to the preset display interface for display and reminding;
[0079] In this embodiment, the robot's adjustable information includes a preset display field. This display field can be set as a text field describing the robot's movable and adjustable state, such as "The sheath has been disengaged, and the robot can be moved." This display field can be adjusted according to the actual situation. After the robot's adjustable information is generated, it can be sent to a preset display interface through a preset information sending path, and a reminder will be displayed on the preset display interface.
[0080] S403, if the switch level signal is low, then generate robot unadjustable information and send it to the preset display interface for alarm reminder.
[0081] In this embodiment, the robot's unadjustable information includes a preset alarm field. This alarm field can be set as a text field describing a state in which the robot cannot be moved or adjusted, for example, "The sheath is not disengaged, and the robot cannot be moved." This alarm field can be adjusted according to the actual situation. After the robot's unadjustable information is generated, it can be sent to a preset display interface through a preset information sending path, and a reminder will be displayed on the preset display interface.
[0082] This embodiment identifies whether the switch level signal is high or low. If the switch level signal is high, it generates robot adjustability information and sends it to the preset display interface for display reminder; if the switch level signal is low, it generates robot non-adjustability information and sends it to the preset display interface for alarm reminder. This effectively achieves the generation and display of corresponding robot adjustability and non-adjustability information based on the high or low level of the switch level signal when the machine is in position adjustment mode.
[0083] Continue to refer to Figure 4 The flowchart of a specific embodiment of step S50 is shown, which includes the following steps:
[0084] Step S501: Determine whether the voltage value of the real-time voltage signal is greater than the preset deformation threshold.
[0085] In this embodiment, after acquiring the real-time voltage signal, a low-pass filter can be used to preprocess the signal to obtain a standard and valid real-time voltage signal. The voltage value of the real-time voltage signal is proportional to the deformation degree of the second monitoring device. By acquiring the voltage value of the real-time voltage signal, it can be effectively determined whether the deformation degree of the second monitoring device has reached the level requiring an alarm. The preset deformation threshold is a voltage threshold corresponding to the voltage value of the real-time voltage signal, and this threshold is used for comparison and judgment. Specifically, this voltage threshold can be preset according to actual conditions and is not limited here.
[0086] If the voltage value of the real-time voltage signal is greater than the preset deformation threshold value, generating a sheath deformation abnormal information and sending the sheath deformation abnormal information to the preset display interface for alarm reminding.
[0087] In the embodiment, the sheath deformation abnormal information includes a preset alarm field, which can be set as a text field for describing the state of abnormal deformation of the sheath connector, for example, “Please note! The current sheath connector deformation is serious”, and the alarm field can be adjusted according to the actual situation. When the sheath deformation abnormal information is generated, the sheath deformation abnormal information can be sent to the preset display interface through the preset information sending path, and displayed and reminded on the preset display interface.
[0088] If the voltage value of the real-time voltage signal is less than or equal to the preset deformation threshold value, generating a sheath deformation normal information and sending the sheath deformation normal information to the preset display interface for display reminding.
[0089] In the embodiment, the sheath deformation normal information includes a preset display field, which can be set as a text field for describing the state of normal deformation of the sheath connector, for example, “The current sheath connector is normal”, and the display field can be adjusted according to the actual situation. When the sheath deformation normal information is generated, the sheath deformation normal information can be sent to the preset display interface through the preset information sending path, and displayed and reminded on the preset display interface.
[0090] The embodiment judges whether the voltage value of the real-time voltage signal is greater than the preset deformation threshold value; if the voltage value of the real-time voltage signal is greater than the preset deformation threshold value, generating a sheath deformation abnormal information and sending the sheath deformation abnormal information to the preset display interface for alarm reminding; if the voltage value of the real-time voltage signal is less than or equal to the preset deformation threshold value, generating a sheath deformation normal information and sending the sheath deformation normal information to the preset display interface for display reminding. Thus, when the current detection category of the system is the sheath state detection, the corresponding sheath deformation abnormal information and sheath deformation normal information can be generated and displayed and reminded according to the voltage of the real-time voltage signal.
[0091] In an optional embodiment of the embodiment, after the sheath deformation state information corresponding to the judgment result is generated and sent to the preset display interface for reminding, the method further includes the following steps:
[0092] Obtaining a driving vibration signal from a third monitoring device;
[0093] In the embodiment, whether the driving mechanism is in a working state can be effectively detected by reading the mechanism operation parameter of the driving mechanism. When the read mechanism operation parameter is a null value, it indicates that the driving mechanism is not in a working state. When the read mechanism operation parameter is not a null value, it indicates that the driving mechanism is in a working state. When the driving mechanism is in a working state, the working sound signal collected from the system database can be extracted according to the current time stamp and the second device identifier corresponding to the third monitoring device. The working sound signal can be acquired at a predetermined time interval to detect the driving mechanism. The predetermined time interval is initially set to 3s and can be adjusted according to the actual situation. The working sound signal is subjected to band-pass filtering by setting a filter frequency band corresponding to the band-pass filtering to achieve filtering processing, so as to effectively remove the noise of the working sound signal and obtain an effective driving vibration signal.
[0094] The real-time voltage signal and the driving vibration signal are input into a pre-trained adjustment parameter calculation model to obtain a driving mechanism adjustment parameter.
[0095] In this embodiment, time-domain analysis is performed on the real-time voltage signal and the driving vibration signal to obtain signal statistical characteristics, including mean, variance, standard deviation, maximum and minimum values, peak-to-peak value (the difference between the maximum and minimum values of the signal), and root mean square value. Frequency-domain analysis is performed on the real-time voltage signal and the driving vibration signal to obtain signal spectral characteristics, including frequency distribution, peak frequency, bandwidth, power spectral density, and spectral shape. The signal statistical characteristics and signal spectral characteristics are combined in a certain order according to a preset feature vector dimension to construct a multi-dimensional feature vector. This multi-dimensional feature vector is then input into a pre-trained adjustment parameter calculation model to obtain the adjustment parameters of the driving mechanism. The adjustment parameters of the drive mechanism can be achieved using a Support Vector Machine (SVM) model. The training steps for an SVM model include: collecting a sample dataset containing multi-dimensional feature vectors and corresponding drive mechanism adjustment parameters; standardizing or normalizing the feature vectors to eliminate dimensional differences between different features; setting the SVM kernel function, which determines the distribution of data in high-dimensional space and the shape of the classification boundary (common kernel functions include linear kernels, polynomial kernels, radial basis function (RBF) kernels, and sigmoid kernels); and setting the hyperparameters of the SVM model, such as the regularization parameter C and kernel function parameters (e.g., RBF). The process involves: 1) Preprocessing the sample dataset, dividing it into training and test sets; 2) Training the SVM model using the training set data to obtain the classifier; 3) Using cross-validation methods (such as k-fold cross-validation) to evaluate the model's generalization ability and determine the optimal hyperparameter combination; 4) Evaluating the model's performance on the test set, with common evaluation metrics including accuracy, precision, recall, F1 score, ROC curve, and AUC value; 5) Optimizing the model based on the evaluation results, including adjusting hyperparameters, changing the kernel function, or improving the feature extraction method.
[0096] The adjustment parameters of the drive mechanism are sent to the drive mechanism for drive adjustment control.
[0097] In this embodiment, the drive mechanism adjustment parameters are control parameters used to adjust the drive mechanism. The drive mechanism adjustment parameters mainly include running speed control parameters and running acceleration control parameters. The running speed and acceleration of the drive mechanism are adjusted by the running speed control parameters and running acceleration control parameters to effectively realize the drive adjustment control of the drive mechanism.

[0101] Further reference is made to Figure 5 In order to further solve the above technical problems, the present application also provides an interventional robot sheath abnormal state early warning device for realizing the interventional robot sheath abnormal state early warning method as described above.

[0102] a sheath 1, a mounting clamping groove 2, a catheter 3, a sheath connecting piece 4, a driving mechanism 5, a first monitoring device 6, and a second monitoring device 7;
[0103] The sheath 1 is connected to the mounting clamping groove 2, the catheter 3 passes through the driving mechanism 5 and is arranged in the sheath 1, the sheath connecting piece 4 is installed between the mounting clamping groove 2 and the driving mechanism 5, the first monitoring device 6 is installed in the mounting clamping groove 2, and the second monitoring device 7 is arranged on the sheath connecting piece 4.
[0104] The embodiment sets the interventional robot sheath abnormal state early warning device comprising a sheath 1, a mounting clamping groove 2, a catheter 3, a sheath connecting piece 4, a driving mechanism 5, a first monitoring device 6, and a second monitoring device 7, thereby effectively acquiring corresponding switch level signals and real-time voltage signals through the first monitoring device 6 and the second monitoring device 7 in real time, so as to effectively monitor the abnormal state and give a risk warning when the interventional robot is running, and ensure the safety and effectiveness of the running process of the interventional robot.
[0105] Further, the driving mechanism 5 is provided with a driver end card slot 51, and one end of the sheath connecting piece 4 is provided with a plug-in end 41 for inserting into the driver end card slot 51 for fixation, the plug-in end 41 is provided with a spring ejector pin 411, and the driver end card slot 51 is provided with a pin female socket 511, and the spring ejector pin 411 and the pin female socket 511 are connected and fixed.
[0106] In this embodiment, the driving mechanism 5 and the sheath connecting piece 4 are respectively provided with the driver end card slot 51 and the plug-in end 41, so that the driving mechanism 5 and the sheath connecting piece 4 can be effectively connected to avoid the sheath connecting piece 4 from falling off the driving mechanism 5 during the operation of the machine.
[0107] In this embodiment, referring to Figure 6 It is shown that the abnormal state early warning circuit of the interventional robot sheath abnormal state early warning device further comprises a master controller Q, a first filter F1, a second filter F2, a first resistor R1, a second resistor R2, a power supply V, a spring ejector pin A1, a pin female socket A2, a first monitoring device K, and a second monitoring device S. One end of the first monitoring device K and the second monitoring device S is connected in parallel to the ground, and the other end of the first monitoring device K and the second monitoring device S is connected to the spring ejector pin A1. The pin female socket A2 is connected in parallel to the first filter F1 and the second filter F2. The first filter F1 and the second filter F2 are connected to the master controller Q. The first resistor R1 and the second resistor R2 are connected in parallel between the first filter F1 and the pin female socket A2, and between the second filter F2 and the pin female socket A2, respectively. The first resistor R1 and the second resistor R2 are connected to the power supply V. One end of the pin female socket A2 is connected to the ground.
[0108] In this embodiment, referring to Figure 7 It is shown that the first monitoring device 6 adopts a micro key switch. When the sheath 1 is installed in the installation card slot 2, the sheath 1 will press the micro key switch to make the micro key switch closed and conductive, so that the circuit becomes low level. When the sheath 1 is separated from the installation card slot 2, the micro key switch will be disconnected and popped up, so that the circuit becomes high level.
[0109] In the present embodiment, the second monitoring device 7 is a thin-film resistance strain gauge, which is fixed in place in contact with the sheath connector 4. The working principle of the thin-film resistance strain gauge is based on the strain effect of resistance materials. When subjected to external forces, the shape and size of the strain gauge will change slightly, which will cause a change in its resistance value. Specifically, when the strain gauge and the sheath connector 4 are synchronously stretched or compressed, the conductive material inside will deform, causing the resistance value to increase or decrease. The thin-film resistance strain gauge can be measured by an external circuit to obtain the corresponding device connection state signal. The resistance of the thin-film resistance strain gauge in the initial state is R, and the greater the deformation, the greater the resistance R, which is similar to a linear change. By applying an excitation voltage Vp to the thin-film resistance strain gauge, in combination with the resistance R1, the change in the thin-film resistance can be converted into a voltage signal, and then the real-time voltage signal V1 is obtained by filtering out interference noise. The relationship is: where R1 is a fixed resistance, Vp is the excitation voltage, V1 is the real-time voltage, and R is the real-time resistance of the thin-film resistance strain gauge. As can be seen from the formula, R increases, and V1 also increases. By collecting the change in the V1 signal, the deformation of the thin-film resistance strain gauge, i.e. the current state of the sheath, can be known.
[0110] Further, the intervention robot sheath abnormal state early warning device further comprises a third monitoring device 8 installed on the driving mechanism 5.
[0111] In the present embodiment, the third monitoring device 8 is an acoustic sensor installed on the driving mechanism 5. The working principle of the acoustic sensor is mainly based on the interaction of sound waves with matter. When sound waves act on the sensor, they will cause the vibration or deformation of some elements inside the sensor, and this mechanical movement is then converted into an electrical signal. The driving vibration signal is effectively obtained from the driving mechanism 5 by the acoustic sensor. In the present embodiment, the third monitoring device 8 is installed on the driving mechanism 5 to effectively obtain the driving vibration signal of the driving mechanism 5 during the operation process, so as to facilitate the adjustment of the driving mechanism adjustment parameters of the driving mechanism 5 according to the driving vibration signal.
