Embodiment 1

[0031] figure 1 It is a structural schematic diagram of embodiment 1 of the cardiac interventional surgery simulator of the present invention, as figure 1 As shown, the cardiac intervention simulator of this embodiment includes a data import module 10 , a three-dimensional modeling module 11 , a simulated catheter 12 , a human-computer interaction device 13 and a controller 14 .

[0032] For example, multiple two-dimensional images of cardiac anatomy can be collected, and the two-dimensional images of cardiac anatomy can be imported into the three-dimensional modeling module 11 through the data import module 10, and the three-dimensional modeling module 11 Three-dimensional modeling technology constructs a digital three-dimensional model of the heart. Wherein, the digital three-dimensional model of the heart in this embodiment is preferably a dynamic digital three-dimensional model of the heart, so as to truly simulate the human heart.

[0033] After constructing the digital...

Embodiment 2

[0037] figure 2 It is a schematic structural view of embodiment 2 of the cardiac interventional surgery simulator of the present invention, as figure 2 As shown, the cardiac interventional surgery simulator of the present embodiment is in figure 1 On the basis of the illustrated embodiment, a two-dimensional image display module 15 is further included.

[0038] In practical applications, the trainer needs to understand the specific structure of the heart in order to perform surgery better. In order to improve the trainer's ability to "see two-dimensional as three-dimensional", this embodiment can use the two-dimensional image display module 15 to display Two-dimensional images corresponding to different postures of the digital three-dimensional model of the heart, so that the trainer can establish the relationship between the two-dimensional image of the heart and the three-dimensional anatomy in the mind.

[0039] Since certain angles of the heart cannot be seen clearly, ...

Embodiment 3

[0043] image 3 It is a structural schematic diagram of Embodiment 3 of the cardiac interventional surgery simulator of the present invention, as image 3 As shown, the cardiac interventional surgery simulator of the present embodiment is in figure 2 The illustrated embodiment further includes a virtual reality module 16 .

[0044] In this embodiment, in order to enable the trainer to better learn cardiac interventional surgery, the virtual reality module 16 can be used to build a digital three-dimensional model of the heart and a virtual scene of the simulated catheter 12. In this way, after the trainer puts on the virtual reality device, the heart The digital three-dimensional model and the simulated catheter 12 can generate three-dimensional visual imaging, so that the trainer can operate the digital three-dimensional model of the heart and the simulated catheter 12 in a virtual scene.

[0045] Such as image 3 As shown, the cardiac interventional surgery simulator of t...

Abstract

The invention discloses a heart interventional operation simulator. The simulator includes a data importing module, a three-dimensional modeling module, a simulating catheter, a man-machine interaction device and a controller; the data importing module is used for importing a two-dimensional image of heart anatomy; the three-dimensional modeling module constructs a digital three-dimensional heartmodel according to the two-dimensional image; the man-machine interaction device receives a control instruction input by a trainer, and the controller determines control parameters of the simulating catheter according to the control instruction in order to control the displacement orientation of the simulating catheter and a damping coefficient between the simulating catheter and other objects; according to a position interaction influence value and a speed interaction influence value, the actual offset of the head of the simulating catheter is determined, the head of the simulating catheter is controlled to be inserted into a target position of the digital three-dimensional heart model according to the actual offset, and the trainer can simulate a catheter operation process during an operation through the head of the simulating catheter. The learning cycle of a heart intervention operation is shortened, and the operation skill of an operator is improved to reduce operation risks.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a heart intervention operation simulator. Background technique [0002] Cardiovascular disease is the number one killer that threatens human health, and its morbidity, disability, and mortality remain high. Cardiac interventional surgery has become an important treatment for this type of disease in the past 10 years. The so-called "intervention" means that the doctor inserts a catheter from the patient's body surface (vascular) into the heart, so as to achieve the role of diagnosis and treatment. This type of operation is different from the traditional "surgical scalpel incision and exposure", in which the operator completes the operation in a three-dimensional organ under a two-dimensional perspective projected by X-rays. Such an operation requires the operator to have the ability to "see two-dimensional as three-dimensional", which requires a long learning period and high su...
