Simulation training device for atrial fibrillation radiofrequency ablation operation

Abstract

The invention discloses a simulation training device for an atrial fibrillation radiofrequency ablation operation. The simulation training device comprises a controller, a driver, an execution motor,a motion conversion mechanism, a motion platform, an atrial model and a femoral vein-to-inferior vena cava model; the placement positions of the atrial model and the femoral vein-to-inferior vena cavamodel accord with a human anatomical structure, and the atrial model is fixed on the motion platform; the controller is connected with the driver, a pulse output port of the driver is connected withthe execution motor, and the driver reads a control program of the controller and drives the execution motor to move; the execution motor drives the motion platform to reciprocate in the front midlinedirection of a human body in an anatomical structure of the human body through the motion conversion mechanism. The simulation training device for atrial fibrillation radiofrequency operation can accurately and truly simulate the displacement influence of breathing of a patient on the atrium in an actual operation, and ablation big head displacement and pressure change caused by displacement.

Description

technical field [0001] The invention relates to an operation simulation training device, in particular to a simulation training device for simulating atrial fibrillation radiofrequency ablation operation. Background technique [0002] Atrial fibrillation refers to the disorder of atrial electrical activity and the rapid and uncoordinated weak peristalsis of the myocardium, resulting in the loss of normal and effective contraction of the atrium. According to statistics, the current adult prevalence rate in my country is 0.77%, and there are about 10 million patients with atrial fibrillation. Since the incidence of atrial fibrillation increases with age, the total number of patients with atrial fibrillation will further increase with the aging of my country's population. Compared with the normal population, atrial fibrillation has a high mortality rate and disability rate, which seriously threatens human health and even quality of life. [0003] There are two main methods of...

Problems solved by technology

Since the existing simulation model is only a static model, which is very different from the actual operation process, the operator cannot perceive the real situation of the operation through the model, so the purpose of simulation cannot be achieved

(2) At present, the atrium model is generally made of ordinary silicone material, which is soft, so that the puncture aperture of the left atrium interatrial septum cannot be enlarged. Once the aperture is enlarged, the atrium will collapse. Therefore, the operator can only use a catheter in the simulation. The simulated operation through the puncture hole of the atrial septum into the left atrium is not compatible with the long sheath, but in the actual operation, the isolation of the pulmonary vein and the linear ablation of the left atrial roof and isthmus must be achieved through the mutual cooperation and relative movement of the long sheath and catheter. The existing model cannot help the operator understand the relative movement of the sheath tube and the catheter, so it cannot realize the simulation of the real surgical situation (3) The existing atrium model is only a model of the normal structure of the atrium, and the shape of the left atrium in different patients during the actual operation is In some patients, the atrium is obviously enlarged, the pulmonary artery is dilated, the spine of the left lung is narrow in some patients, the lower right lung is extremely low in some patients, and the upper right lung is forward in some patients. Deterministic, also cannot be simulated by a simple normal left atrium model

(4) In the actual operation, the skin and subcutaneous tissue of the femoral vein puncture site and the tortuous part of the femoral vein will often wrap the long sheath, making it difficult to fully transmit the torque of the rotating long sheath to the head. Appropriate torque to overcome this obstacle, so that the degree of rotation of the long sheath will not be too much or too little, which is also one of the difficulties in surgery, and the existing femoral vein model is only a straight silicone tube, and the sheath tube entrance Cut the opening for rough silicone, which cannot simulate the real situation of the femoral vein puncture in real surgery

Therefore, the device cannot be used for the reduction and simulation of the real surgical environment.
