System for simulating endovascular intervention operation

Abstract

Embodiments of the present invention provide a system for simulating the endovascular intervention operation. The system comprises an image acquiring device, a model establishment device, a physical surgical instrument and a display. The image acquiring device is configured to acquire the medical image data of blood vessels, perivascular tissues and perivascular organs that are subjected to the simulation for the endovascular intervention operation, wherein the medical image data are specified for a patient. The model establishment device is configured to establish a three-dimensional geometric model of the blood vessels, the perivascular tissues and the perivascular organs in the medical image data. The physical surgical instrument is operated by a user to simulate the endovascular intervention operation. The model establishment device is also configured to control the motion trajectory of a three-dimensional model of the surgical instrument in the three-dimensional geometric model of the blood vessels according to the operation of the user on the physical surgical instrument. The display is configured to display the three-dimensional geometric model of the blood vessels, the perivascular tissues and the perivascular organs and the motion trajectory of the three-dimensional model of the surgical instrument in the three-dimensional geometric model of the blood vessels. According to the technical scheme of the invention, the operation plan of a patient can be formulated in the personalized manner. Meanwhile, the operation path is optimized and the operation can be rehearsed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intravascular interventional operation simulation system. Background technique [0002] Interventional surgery is a method of cutting a small hole (the size of a grain of rice) in a certain part of the human body under the guidance of medical imaging equipment, and then sending interventional devices such as guide wires and catheters into the human body to diagnose and locally treat the lesion in the body. minimally invasive surgery. Interventional therapy has the characteristics of no surgery, less trauma, quick recovery and good effect. At present, the guidance of surgical instruments during interventional surgery mainly relies on images obtained by two-dimensional real-time perspective imaging technology. According to two-dimensional images to guide the operation of instruments in three-dimensional space, accurate and efficient hand-eye coordination and a lot of pr...

Problems solved by technology

These methods all have their own obvious shortcomings, which affect the training effect: the first method can only be used to understand the outside of the blood vessel (such as the course of the blood vessel, the innervation area and the adjacent area) due to the limited number of donated corpses and the limitation of the blood coagulation time. structure)

In the second way, the fixed human body model cannot reflect the variability and diversity of the human body structure, and the internal structure of the organs

In the third way, the anatomical structure of animals is different from that of the human body, and the training environment is not ideal. In addition, due to the limitations of animal anesthesia and radiation equipment matching, there are almost no opportunities for endovascular training on animals.

In traditional surgery, doctors formulate surgical plans based on human anatomy knowledge obtained from specimens or books, combined with clinical experience, and perform preoperative surgical rehearsals in their own brains. The shortcoming of this method lies in the quality of surgical plans Depending on the individual clinical experience and skills of doctors, it is not conducive to discovering problems in the entire operation process in advance, which not only increases the risk of surgery, but also does not conform to ethics and morals, and is likely to cause medical disputes. learn from each other

[0004] A training simulator for vascular interventional surgery is also provided in the prior art, which includes a simulated training platform, a dual-screen simulated surgery monitor, a simulated operating table, a simulated patient and a software platform. However, since the simulated patient is fixed and cannot reflect the variability, diversity and internal structure of the human body structure, the above-mentioned vascular interventional surgery training simulator is only suitable for providing a training platform for beginners, and cannot be aimed at a certain Personalize patients to formulate surgical plans, optimize surgical routes, and perform operations such as surgical rehearsals
