That is, the catheter body (3) made of wire, the working part deformed by the operator's operation at the tip of the catheter body (3), the tip electrode (1) provided at the tip of the working part, the tip electrode ( Ring electrode (3), which is a plurality of electrodes located on the catheter body (3) side relative to 1), plug (4) provided for sending current to the ring electrode (3) and the tip electrode (1), etc. And an actuator (5) for operating the operating part, and a handle (6) for inserting / withdrawing the entire catheter body (3).

  I will give another explanation.

  Patent Document 1 discloses a cardiovascular model suitable for heart catheter insertion practice, coronary stenosis discovery, removal training, vascular endoscopic diagnosis, practice, and the like.

  However, Patent Document 1 has a problem that it does not indicate what kind of biological information is detected during the catheter examination.

  In Patent Document 2, a catheter can be inserted, and an organ model simulating an organ, a catheter position determining means for determining the position of the catheter inserted into the organ model, and a catheter determined by the catheter position determining means A catheter examination simulation system is disclosed that includes simulated data generation means for generating biological information data in a simulated manner corresponding to a position and a display unit for displaying the biological information data.

  In this document, a simulation using an organ model is possible, and a more realistic experience is possible in the practice of inserting a cardiac catheter than in Patent Document 1.

Japanese Utility Model Publication No. 5-50477 JP, 2005-241883, A By the way, the treatment method with respect to a heart disease progressed rapidly by development of the information processing technology which supports the high functionalization of a catheter, and its high functionalization. Catheters have been developed according to the type of movement required, and furthermore, it has become possible to use high frequencies by embedding electrodes at multiple locations. They also enabled a treatment called “catheter ablation treatment”. A configuration used for the treatment is shown in FIG.

  In FIG. 12, while acquiring an intracardiac electrocardiogram and a body surface electrocardiogram with respect to the heart which is an affected part of a patient, a plurality of electrode catheters including electrodes are inserted, and a stimulator (FIG. 14) is inserted through an amplifier. An EP analysis system is provided. The patient's back is provided with a counter electrode plate.

  “Catheter ablation treatment” is a cardiac disease that causes tachyarrhythmia by necrotizing the site in the myocardium that is causing the disease, and electrically blocking the electrophysiological tissue causing the arrhythmia. Is a cure. A general high-frequency generator used for this treatment is shown in FIG. By raising the temperature in the vicinity of the tip electrode by passing a high-frequency current through the tip electrode (1) and the counter electrode plate of the electrode catheter.

  In order to perform catheter ablation, it is necessary to accurately determine the cause of the heart rhythm disorder in the ventricle. This position measurement is performed through an electrophysiological examination, specifically, a stimulator shown in FIG. In the electrophysiological examination, the potential is analyzed by position analysis using a mapping catheter inserted into the ventricle.

  As a technique for assisting this catheter ablation treatment, for example, the positional relationship (association) between mapping data and the anatomical form of the heart is grasped, the target site of the ablation treatment is accurately identified, and the location As a technique for accurately navigating, there is an “electrophysiological mapping device” described in Patent Document 3.

JP 2005312962 A

  In order to perform actual catheter ablation treatment, in addition to medical knowledge and catheter manipulation techniques, electrophysiological knowledge is required. However, there are not many doctors who have electrophysiological knowledge in addition to medical knowledge and catheter manipulation techniques. For example, it is difficult to learn without the theory and practice of electrophysiology to identify the position to be ablated from the relationship between the position of the electrode of the catheter and the electrocardiogram.

  Thus, there is a shortage of such doctors to meet the increasing demand for catheter ablation treatment. Therefore, at present, an engineer who has electrophysiological knowledge and medical knowledge in an actual treatment scene is often advanced in the form of assisting a doctor who has a catheter operation technique.

  According to Patent Document 2, medical knowledge and catheter operation techniques can be learned. However, no device or method for learning electrophysiological knowledge before actual treatment is provided including Patent Documents 3 and 4.

The problem to be solved by the present invention is to provide a technique capable of learning necessary electrophysiological knowledge together with a catheter operation technique before performing an actual catheter ablation treatment. The object of the present invention is to provide a device capable of practically learning electrophysiological knowledge in addition to medical knowledge and catheter operation techniques.

This is a cardiac catheter simulation device as described above.

(Glossary)
The “three-dimensional data” may be coordinates determined with the pitch of the three-dimensional mesh being equally spaced. However, since the size of the heart is different among individuals but the region is almost the same, A model using a model that determines the coordinates by specifying the number of meshes is superior in terms of usability.

  Hereinafter, the present invention will be described more specifically with reference to the drawings and embodiments. The drawings used here are FIGS. 1 to 10.

(Figure 1)
FIG. 1 is a hardware configuration diagram of the present embodiment, and FIG. 2 is a corresponding software configuration diagram.

  A digital conversion device for digitizing the movement of an actual catheter (six catheters in the figure), a personal computer that stores the shape and movement of the model heart as digital data (hereinafter referred to as a three-dimensional heart model) (PC1). The PC 1 synthesizes the digital data output from the actuator and the digital data of the shape and movement of the model heart so as to perform calculation and output so that video can be output to the monitors (M1, M2).

  The reason for providing a plurality of monitors (M1, M2) is as follows. First, while the model heart and the catheter are three-dimensional, the monitor can output a two-dimensional image, so that it can be used to output images from different angles. It may also be necessary to display all when many catheters must be inserted.

  The above-mentioned actuator converts the actual movement of the catheter (the total insertion amount, the rotation amount of the main body, the bending amount of the tip) into an operation that can be easily measured by the actuator, and further converts the physical quantity converted into the operation that can be easily measured. It is a device to digitize.

  The operation stick of the catheter is the same as the actual one, but the configuration in the actuator is a slightly different simulated catheter. The simulated catheter is also provided with a simulated catheter electrode. This electrode is provided at the tip and at several other locations, and it is possible to calculate by calculation which position in the three-dimensional heart model the electrode exists.

  Other details are omitted.

  The PC 2 is for displaying a polygraph, and polygraph data prepared in advance for the model heart is stored in a storage device (hard disk drive).

  As a reasonable model for converting the shape of the heart into three-dimensional coordinates, the “Way-Harmi model” is used. In this model, the coordinates are 56 dots vertically and horizontally and 90 dots in the height direction.

  In addition, an intracardiac potential data table for calculating an intracardiac potential corresponding to the place (two pairs) where the catheter electrode of the simulated catheter used for the actuator is located is also stored. Using the above-described three-dimensional coordinates, a potential difference from the reference point (0, 0, 0) is prepared in advance as a table.

  The two monitors M3 and M4 for displaying the polygraph are prepared when an intracardiac electrocardiogram and a body surface electrocardiogram are acquired and both of them must be output simultaneously.

  The PC 3 manages the operation of the stimulator (electric stimulation device). An actual stimulator is a device for applying a current to a catheter electrode disposed on a catheter to give a stimulus to the heart. It is used to specify a site to be ablated from an electrocardiogram (polygraph) that changes by applying electrical stimulation.

  However, what is used in the present embodiment is a simulated simulator that makes it appear that a current is passed through a catheter electrode disposed on the simulated catheter as if it were simulated.

  As shown in FIG. 8, screen output simulating a simulator is performed, and information indicating that a current has been simulated is transmitted to the junction box server of the PC 2 and reproduced on the polygraph. Also, a channel setting screen as shown in FIG. 9 can be output.

  The PC 4 is in charge of the ablation operation. Actual ablation means that a high-frequency current is passed between the electrode at the tip of the catheter and a counter plate located on the back of the patient to raise the tip of the catheter to about 60 degrees Celsius. It is a high-frequency generator that causes necrosis.

  However, what is used in this embodiment is a simulated high-frequency generator that makes it appear as if a high-frequency current is passed through the position of an electrode disposed at the tip of the simulated catheter.

  As shown in FIG. 10, screen output simulating a high frequency generator is performed, and information indicating that a high frequency has been simulated is transmitted to the junction box server of the PC 2 and reproduced on a polygraph.

(Function)
Hereinafter, the operation of the present embodiment will be described with reference to FIGS. The numbers in parentheses correspond to the order in the figure.

(Figure 3)
First, the physical movement generated by operating the catheter is converted into digital data by a digital conversion device, and the digital data is transmitted to the PC 1 as operation information (1). The transmitted operation information is received by the actuator I / F (2), synthesized with the 3D heart model data stored in advance in the 3D heart model, and output to the monitor (3). In FIG. 3, “virtual X-ray” is illustrated on the monitor that the three-dimensional heart model and the movement of the catheter inserted into the heart model are displayed on the monitor even though there is no patient. This is because that.

  The PC 1 calculates electrode coordinates for specifying the position of the catheter, and transmits the electrode coordinates to the PC 2 as electrode coordinate data (4).

(Fig. 4)
As shown in FIG. 4, the junction box of the PC 2 that has received the electrode coordinate data (5) performs intracardiac potential calculation using the electrode coordinate data (6), calculates the potential data, and returns it to the junction box. (7). The polygraph is displayed and output using the potential data thus calculated (8).

(Fig. 5)
FIG. 5 shows information exchange (PC3 and PC2) related to the simulated stimulator for specifying a part for executing ablation.

  The simulated simulator transmits stimulus information to the PC 2 while the operator confirms the simulated simulator screen as shown in FIG. 8 (9). The transmitted stimulus information is received by the junction box server and sent to the junction box (10). And it is used for intracardiac potential calculation (11).

  When the intracardiac potential calculation is completed, the calculated potential data is returned to the junction box (12), and the potential data is displayed on the polygraph (13).

  The operator corrects the position of the catheter or adjusts the tip shape while confirming the position of the polygraph output by the operation shown in FIG. 5 or the position of the catheter output as a virtual X-ray. Then, the transmission of the stimulus information shown in FIG. 5 is repeated. At this time, the operator can practice the operation of the catheter and confirm the electrophysiological knowledge.

(Fig. 6)
FIG. 6 shows information exchange (PC4 and PC2) regarding the case where the ablation is executed in a rigorous manner.

  Assume that a site for performing ablation has been identified by several corrections and adjustments. Then, the ablation information is transmitted to the PC 2 while the operator confirms the operation screen of the simulated high frequency generator as shown in FIG. 10 (14). The transmitted ablation information is received by the junction box server and sent to the junction box (15). Then, ablation is performed, and the predetermined part changes to a burned out state. Ablation information is used for the intracardiac potential calculation in that case (16).

  When the intracardiac potential calculation is completed, the calculated potential data is returned to the junction box (17), and the potential data is displayed on the polygraph (18). If the burned-out site is an affected part to be treated, the polygraph output at this time should display a waveform at the time of successful surgery.

(Fig. 7)
FIG. 7 shows information exchange (PC1 and PC2) when the channel setting screen is used.

  Assume that the operator changes the channel setting while looking at the polygraph as shown in FIG. The channel information is transmitted from the junction box to the PC 1 via the junction box server (19). Then, electrode coordinates based on the changed channel information are returned to the junction box server (20). The returned electrode coordinates are subjected to intracardiac potential calculation via the junction box (21), and the waveform output to the polygraph is performed using the calculated potential data (22).

  The present invention is not limited to a cardiac catheter. Any medical simulation that requires electrophysiological knowledge can be used, for example, for a medical simulation of a brain catheter.
