Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and particularly to an integrated arterial support stent and an auxiliary system. Background Technique

[0002] In the field of modern medicine, arterial diseases seriously threaten human health, such as coronary heart disease, peripheral arterial diseases, etc. Lesions such as arterial stenosis, occlusion or aneurysm will cause obstruction of blood supply, leading to a series of complications and even endangering life. At present, arterial stent implantation has become an important means to treat such diseases. Among them, the integrated stent has gradually attracted attention in clinical applications due to its unique advantages, such as reducing surgical steps and reducing the risk of infection.

[0003] However, the existing integrated stents lack an auxiliary system to optimize the stent state and working state, which may lead to inaccurate positioning of the patient's lesion by the integrated stent. Therefore, we propose an integrated arterial support stent and an auxiliary system. Summary of the Invention

[0004] The purpose of the present invention is to provide an integrated arterial support stent and an auxiliary system.

[0005] To solve the problems raised in the above background technique, the present invention provides the following technical solutions: an integrated arterial support stent and an auxiliary system, the auxiliary system includes an image storage module, a stent positioning module, a pressure monitoring module, a detection module, a data processing module and a remote control module;

[0006] The image storage module is used to store the overall arterial image data of the current patient;

[0007] The stent positioning module is used to obtain the position information of the integrated stent in the artery;

[0008] The pressure monitoring module is used to analyze the blood pressure and blood flow velocity in the current artery;

[0009] The detection module is used to obtain the arterial inner wall image data captured by the integrated stent during its movement in the artery;

[0010] A matching unit is set in the data processing module. The data processing module retrieves the overall artery image data in the image storage module, analyzes the overall artery feature data based on the overall artery image data, and transmits the overall artery feature data to the matching unit. The detection module transmits the captured artery inner wall image data to the data processing module. The data processing module analyzes the regional artery feature data in the captured artery inner wall image data and transmits the regional artery feature data to the matching unit. The matching unit matches the overall artery feature data with the regional artery feature data to obtain the position feature data of the current integrated stent, combines the position feature data with the position information, and then the data processing module plans the movement path of the integrated stent.

[0011] The remote control module is used to control the magnetic field of the integrated stent and control the integrated stent by changing the magnetic field.

[0012] As a further solution of the present invention: The image storage module includes a patient identification unit and an external connection unit. The external connection unit is used to connect to the hospital system. After the patient identification unit identifies the patient information, the patient identification unit retrieves the overall artery image data taken by the patient in the hospital system and transmits the overall artery image data to the image storage module for storage.

[0013] As a further solution of the present invention: The stent positioning module includes an electromagnetic sensor and a signal receiving unit. The electromagnetic sensor is installed on the integrated stent. The signal receiving unit is used to receive the electromagnetic signal transmitted by the electromagnetic sensor in real time. After the signal receiving unit receives the electromagnetic signal transmitted by the electromagnetic sensor, it converts the position information transmitted by the electromagnetic signal into electronic data.

[0014] As a further solution of the present invention: A photographing unit and an ultrasonic unit are provided in the detection module. Both the photographing unit and the ultrasonic unit are installed at the front end of the integrated stent. The photographing unit is used to photograph the artery inner wall image data. The ultrasonic unit is used to detect the thickness, diameter, length, and curvature data of the blood vessel inner wall in the artery. The detection module integrates the artery inner wall image data, the blood data in the pressure monitoring module, and the artery data detected by the ultrasonic unit into normalized data.

[0015] As a further solution of the present invention: a movement evaluation model and a support evaluation model are set in the data processing module. After the matching unit completes the matching, the data processing module determines whether the current integrated stent has moved to the support point by normalizing the data. When the data processing module does not recognize that the integrated stent has moved to the support point, the data processing module imports the normalized data into the movement evaluation model, and the movement evaluation model evaluates the movement data of the integrated stent. When the data processing module recognizes that the integrated stent has moved to the support point, the data processing module imports the normalized data into the support evaluation model, and then the support evaluation model evaluates the working state of the integrated stent according to the normalized data.

[0016] As a further solution of the present invention: the movement evaluation model generates an evaluation value for the movement state data of the integrated stent through a formula, and the specific formula is as follows:

[0022] As a further solution of the present invention: an early warning unit is provided in the remote control module, and thresholds T 1 , W 1 , T 2 and W 2 are set in the early warning unit. When T 2 <T ≤ T 1 and W 2 <W ≤ W 1 , the early warning unit generates secondary early warning data to notify the operator to adjust the moving path of the integrated stent. When T 2 ≥T and W 2 ≥W, the early warning unit generates primary early warning data, and the remote control module transmits the data to the data processing module, and the data processing module generates a planned route for the current position of the integrated stent.

[0023] In addition, the present invention also provides an integrated stent, and this integrated stent is applicable to the usage method of an auxiliary system for an arterial support integrated stent.

[0050] In addition, the present invention also provides an integrated stent, and this integrated stent is applicable to a usage method of an auxiliary system for an arterial support integrated stent.

[0051] Example 1. Please refer to the appendix Figure 1 . After the integrated stent enters the patient's body, use the stent positioning module to obtain the position data of the integrated stent, and then match the position data with the overall arterial image data of the patient, so as to quickly locate the position of the integrated stent in the artery, and further facilitate the auxiliary system to plan and guide the path of the integrated stent.

[0052] Example 2. Please refer to the appendix Figure 1, by switching between the support evaluation model and the movement evaluation model, the data processing module can evaluate the state of the integrated stent as needed, thereby improving the evaluation accuracy of the data processing module and facilitating the subsequent control of the integrated stent.

[0053] Embodiment 3. Please refer to the appendix Figure 1 , the remote control module adjusts the movement path of the integrated stent by controlling the magnetic field strength, and then adjusts the movement state of the integrated stent in the artery. A prediction unit is set in the remote control module to analyze the control data of the operator using the prediction unit and predict the movement data of the integrated stent through a formula. The specific formula is as follows:

[0054]

[0055] Where, M represents the predicted movement data of the integrated stent, Q represents the total value of T or W in different past time periods, n represents the number of T or W in different past time periods, and S represents the predicted time.

[0056] Specifically, through the image storage module with the help of the patient identification unit and the external unit, the overall arterial image data of the patient is retrieved and stored from the hospital system. After the data processing module obtains these data, it deeply analyzes the overall arterial feature information therein. At the same time, the stent positioning module, through the electromagnetic sensor and the signal receiving unit installed on the integrated stent, real-time collects the stent position information and transmits it to the data processing module. The data processing module matches and analyzes the overall arterial feature data with the regional arterial feature data in the arterial internal image data, accurately identifies the arterial inner wall features. Based on these analysis results, the data processing module can adjust in real time during the stent movement path, thereby more accurately positioning the integrated stent in the artery and greatly improving the positioning accuracy.

[0057] Specifically, during the movement of the integrated stent in the artery, the present invention uses the movement evaluation model to dynamically evaluate its movement state. The movement evaluation model comprehensively considers factors such as the positioning data of the stent positioning module, the spatial data of the shooting unit, and the force condition of the arterial blood vessel, and calculates the evaluation value T through a specific formula. According to the evaluation value T, the operator can timely adjust the movement state of the integrated stent to ensure its stable movement. When the stent reaches the support point, the support evaluation model starts to play a role. This model combines data such as the degree of blood vessel stenosis, the pressure in the blood vessel, and the thickness of the blood vessel wall, and calculates the evaluation value W through a corresponding formula. According to the evaluation value W, the operator can flexibly adjust the working state of the integrated stent, effectively avoiding damage to the artery caused by the stent and ensuring the normal function of the artery.

[0058] Specifically, the remote control module of the present invention is provided with a warning unit, and this unit pre-sets thresholds T 1 、W1 , T 2 and W 2 During the operation of the support, the early warning unit continuously monitors the movement assessment value T and the support assessment value W. 2 <T≤T 1 or W 2 <W≤W 1 When T 2 ≥T or W 2 When the value of T or W is greater than or equal to W, a first-level warning is issued and the data is transmitted to the data processing module to re-plan the support position. In addition, the operator uses the prediction unit in the auxiliary system to calculate the T or W value according to the formula in different time periods in the past. Predicting the bracket movement data enables precise control of bracket movement and working status, further improving the safety and effectiveness of operations.
