[0028] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0029] The following describes in detail, with reference to the accompanying drawings, a transcatheter lung valve replacement simulation simulator 100 according to an embodiment of the present invention.

[0030] like Figures 1 to 3 As shown, the transcatheter lung valve replacement simulation simulator 100 according to an embodiment of the present invention includes a reservoir 10 and a model assembly 20.

[0031] Specifically, the side wall of the liquid storage tank 10 is provided with a mounting port, the mounting port is provided with a luer 11, the luer 11 is used for penetrating through a surgical instrument, and dynamic sealing is realized with the surgical instrument, the model assembly 20 is arranged in the liquid storage tank 10, the model assembly 20 is used for simulating cardiovascular structures of a human body, and the model assembly 20 comprises a pulmonary artery simulation pipe 22, a heart simulation body 21 and a inferior vena cava access pipe 23 connected in sequence; wherein the heart simulation body 21 is provided with a right atrium and a right ventricle, and a tricuspid valve simulation body between the right atrium and the right ventricle, the pulmonary artery simulation pipe 22 communicates with the right ventricle, and a first end of the inferior vena cava access pipe 23 communicates with the right atrium, and a second end of the inferior vena cava access pipe 23 corresponds to the position of the luer 11.

[0032] In other words, as shown in the drawings, Figures 1 to 3 The catheter pulmonary valve replacement simulation simulator 100 according to the embodiment of the utility model mainly comprises a liquid storage tank 10 and a model assembly 20, wherein the liquid storage tank 10 can be made of acrylic material, the liquid storage tank 10 is provided with an upper opening, so as to facilitate water injection into the liquid storage tank 10, and one side wall of the liquid storage tank 10 is provided with a mounting port communicating with the inside of the liquid storage tank 10. One end of the mounting port is fixedly connected with a sealing gasket through a flange structure. Specifically, the sealing gasket can be made of rubber or silicone, and the sealing gasket is tightly fixed through the flange structure. The sealing gasket is provided with a mounting hole corresponding to the mounting port, and the size of the mounting hole corresponds to that of the luer 11, so that the first end of the luer 11 can penetrate through the sealing gasket from the mounting hole, and the luer 11 can be fixed on the sealing gasket, so as to ensure the sealing property of the connection. The luer 11 is used for penetrating through a surgical instrument, and dynamic sealing is realized with the surgical instrument. The surgical instrument can be a guide sheath, for example, a 22F large sheath and the like.

[0033] As shown in the drawings, Figures 1 to 3 The model assembly 20 is installed in the liquid storage tank 10, and the cardiovascular structures of a human body can be simulated through the model assembly 20. Specifically, the model assembly comprises a pulmonary artery simulation pipe 22, a heart simulation body 21 and a inferior vena cava access pipe 23 connected in sequence, wherein the heart simulation body 21 and the pulmonary artery simulation pipe 22 can be prepared according to image data of a patient by using 3D printing technology. The heart simulation body 21 has a right atrium and a right ventricle, and a tricuspid valve simulation body between the right atrium and the right ventricle. The tricuspid valve simulation body is prepared from an elastic material, so as to achieve the effect of tricuspid valve simulation.

[0034] As shown in the drawings, Figure 1 and Figure 2As shown, the pulmonary artery simulation tube 22 is a three-way tubular structure, one end of the pulmonary artery simulation segment is in communication with the right ventricle, and the first end of the inferior vena cava access tube 23 is in communication with the right atrium, so that the model assembly 20 simulates the cardiovascular structure involved in the transcatheter pulmonary valve replacement surgery. In this embodiment, the second end of the inferior vena cava access tube 23 is spaced apart from the first end of the Luer head 11 and corresponds to the position of the Luer head 11, so that the surgical instrument can be inserted into the inferior vena cava access tube 23 to facilitate surgical simulation.

[0035] It should be noted that the position at which the pulmonary artery simulation tube 22 is connected to the heart simulation body 21 corresponds to the position at which the human heart and the pulmonary artery are connected, and the position at which the inferior vena cava access tube 23 is connected to the heart simulation body 21 corresponds to the position at which the human heart and the inferior vena cava are connected, and those skilled in the art should understand that this embodiment will not be described again.

[0036] When the transcatheter pulmonary valve replacement simulation simulator 100 according to the embodiment of the utility model is used for simulation training, first, a guide sheath is inserted into the Luer head 11, and water is added into the liquid storage tank 10, so that the liquid level is higher than the entire model assembly 20. In this case, the water enters the inside of the model assembly 20, which can simulate body fluid, is conducive to reducing the friction between the surgical instrument and the model assembly 20, and can more realistically simulate the surgical process. Then, a guide wire is inserted into the guide sheath, and the guide sheath is pushed to pass through the inferior vena cava access tube 23 and enter the right atrium. After the guide sheath enters the right atrium, the direction of the guide sheath is adjusted to pass through the tricuspid valve orifice and enter the right ventricle. Then, in the right ventricle, the guide sheath is further operated to reach the position of the pulmonary artery simulation tube 22 in communication with the right ventricle. Subsequently, a delivery system loaded with an artificial pulmonary valve is sent to the position of the pulmonary valve through the guide sheath and the guide wire, and finally the artificial valve is released at the appropriate time to accurately anchor on the pulmonary valve annulus. After the valve is completely released, the corresponding surgical instruments are sequentially removed.

[0037] Therefore, the transcatheter pulmonary valve replacement simulation simulator 100 according to the utility model can simulate the cardiovascular structure of the actual human body through the model assembly 20 provided thereby, can provide a more realistic surgical operating environment, greatly shortens the learning curve of the student for the transcatheter pulmonary valve replacement, and improves the proficiency and skill of the student in operating the related instruments in the surgical process, such as the accurate operation of the guide sheath and the guide wire, the accurate release and anchoring of the artificial valve, etc., which is conducive to the student to master the surgical operation process and reduce the mistakes in the actual surgery, and finally achieves the purpose of improving the safety of the patient surgery. Moreover, the transcatheter pulmonary valve replacement simulation simulator 100 can be repeatedly used, which reduces the teaching cost and avoids the risk of causing harm to the patient.

[0038] According to one embodiment of the utility model, the heart simulation body 21 is configured as a right heart structure simulation body.

[0039] That is, the heart simulator 21 is not a simulation structure of the whole human body heart, but only a right heart structure simulator, so that the overall design of the transcatheter pulmonary valve replacement simulation simulator 100 can be simplified, unnecessary complexity can be reduced, and the production cost can be effectively reduced.

[0040] In some specific embodiments of the present application, the side wall of the heart simulator 21 away from the bottom of the liquid storage tank 10 is provided with a first operation port 211 corresponding to the position of the right atrium.

[0041] Specifically, as shown in Figure 1 and Figure 2 , the upper side wall of the heart simulator 21 is provided with a first operation port 211 at a position corresponding to the right atrium. In the operation, the end of the guide sheath needs to be turned to a position corresponding to the tricuspid valve simulator to enter the right ventricle. However, when the student's instrument operation proficiency is poor and the end of the guide sheath cannot be turned to the correct position, the hand or tool can be inserted into the right atrium from the first operation port 211 to manually adjust the end of the guide sheath to the correct position. Thus, the student can enter the next step of practice, which is beneficial to the modular practice of the operation and can further shorten the learning curve of the student for the transcatheter pulmonary valve replacement.

[0042] According to an embodiment of the present application, the wall of the side of the heart simulator 21 away from the bottom of the liquid storage tank 10 is provided with a second operation port 212 corresponding to the position of the right ventricle.

[0043] Specifically, as shown in Figure 1 and Figure 2 , the upper side wall of the heart simulator 21 is provided with a second operation port 212 at a position corresponding to the right ventricle. In the operation, the end of the guide sheath needs to be turned to a position corresponding to the pulmonary artery simulation tube 22 to enter the pulmonary artery simulation tube 22. However, when the student's instrument operation proficiency is poor and the end of the guide sheath cannot be turned to the correct position, the hand or tool can be inserted into the right ventricle from the second operation port 212 to manually adjust the end of the guide sheath to the correct position. Thus, the student can enter the next step of practice, which is beneficial to the modular practice of the operation and can further shorten the learning curve of the student for the transcatheter pulmonary valve replacement.

[0044] In some specific embodiments of the present application, the tricuspid valve simulator is detachably connected with the heart simulator 21.

[0048] Specifically, as shown in Figure 1 and Figure 2 , the side wall of the inferior vena cava access tube 23 near the bottom of the liquid storage tank 10 is provided with a support seat 231, which can be integrally formed with the inferior vena cava access tube 23. The support seat 231 and the liquid storage tank 10 are fixedly connected together by adhesion or screw fixation, so as to realize the connection of the entire model assembly 20 and the liquid storage tank 10, which is simple in structure and convenient for production and assembly.

[0049] In some specific embodiments of the present application, the heart simulator 21 extends a connecting tube 213 on one side close to the inferior vena cava access tube 23, the connecting tube 213 communicates with the right atrium, and the trans-catheter pulmonary valve replacement simulation simulator 100 further comprises: a throat clamp member 24, the connecting tube 213 is inserted into the first end of the throat clamp member 24, and the inferior vena cava access tube 23 is inserted into the second end of the throat clamp member 24.

[0050] That is, as shown in Figure 1 and Figure 2 , the heart simulator 21 and the inferior vena cava access tube 23 are detachably connected together through the throat clamp member 24. Specifically, the heart simulator 21 extends a connecting tube 213 communicating with the right atrium at the position connected with the inferior vena cava access tube 23, the connecting tube 213 is inserted into the first end of the throat clamp member 24, and the inferior vena cava access tube 23 is inserted into the second end of the throat clamp member 24.

[0051] According to an embodiment of the present application, the pulmonary artery simulation tube 22 is detachably connected with the heart simulator 21.
