Problems solved by technology

At present, this technology is mainly used for aortic valve replacement, and the application of transcatheter technology for mitral valve is still very limited due to the complex anatomical structure, pathological changes, and lack of effective evaluation and device design of the mitral valve. Therefore, , residual regurgitation, paravalvular leak, left ventricular outflow tract obstruction, left heart failure and other complications are difficult to effectively evaluate

Embodiment 1

[0062] The simulated object of this embodiment: mitral valve insufficiency patient 3D model simulates TMVP in vitro;

[0063] The condition of the patient: 76 years old, mitral valve insufficiency was found for 2 years, the prolapse of the P2 area of ​​the posterior valve was serious, and a large amount of regurgitation (30ml).

[0064] Surgical planning: percutaneous mitral valve edge-to-edge angioplasty.

[0065] Simulation process:

[0066] (1) Print the 3D model of the patient;

[0067] (2) Install the device, collect relevant preoperative data, set patient-specific parameters, turn on the water pump and collect simulations, start transcatheter mitral annuloplasty simulation, and collect relevant postoperative data. The preoperative ultrasound data were measured on the 3D printed model, such as image 3 As shown in the figure, there is a large amount of mitral valve regurgitation and valve leaflet prolapse, and transthoracic ultrasound shows that the mitral valve is not...

Embodiment 2

[0074] Simulated object: TMVR for patients with mitral valve stenosis and regurgitation;

[0075] The patient's condition: 72 years old, rheumatic heart disease for more than 10 years, moderate mitral valve stenosis with moderate regurgitation;

[0076] Surgical planning: Percutaneous mitral valve replacement, with No. 36 intervening mitral valve.

[0077] Simulation process:

[0078] (1) Print the 3D model of the patient;

[0079] (2) Install the device, the patient's preoperative ultrasound data is measured on the 3D printing model, such as Figure 5 Shown; The patient's preoperative setting parameters are shown in Table 3;

Abstract

The invention discloses a 3D model in vitro simulation device and a system for the transcatheter mitral valve disease treatment surgery. The device disclosed in the invention includes a water pump, aballoon pump, a balloon, an ultrasonic detector, a pressure sensor, and a blood flow detector, wherein the water pump is used for supplying a liquid to the 3D model to be tested to simulate blood flow; the balloon is used for simulating the peripheral tissues of the heart in the human body; the balloon pump simulates the changes of the peripheral tissues during cardiac contraction and relaxation by inflating and deflating the balloon; and the ultrasonic sensor, the pressure sensor and the blood flow detector are respectively used for detecting relevant surgical parameters during simulation. The disclosed simulation system further includes a 3D printing system. By connecting the 3D printing model to a specific simulation device, the device of the invention can accurately simulate transcatheter mitral valve plasty and replacement before operation, evaluate patient-specific risks and possible complications, and reduce surgical complications and risks.

Description

technical field [0001] The invention belongs to the technical field of in vitro simulation equipment for transcatheter valve repair and replacement in cardiovascular surgery, and relates to a 3D model in vitro simulation device for transcatheter mitral valve disease treatment operation. Background technique [0002] Senile mitral valve disease is the most common valvular disease clinically. The incidence rate of the elderly population is about 7-13%, which seriously affects the quality of life of the elderly population. Once diagnosed with severe mitral insufficiency, the traditional treatment method requires a thoracotomy to perform valve replacement or repair surgery under extracorporeal circulation. The operation risk is extremely high and the trauma is extremely high. [0003] The rapid development of transcatheter mitral valve disease treatment in recent years (including transcatheter mitral valvuloplasty (TMVP) and replacement (TMVR)) does not require thoracotomy and e...
