Endovascular interventional surgery simulation system

Abstract

A surgical simulation system for endovascular intervention enables operations including customizing a surgical scheme for a patient, optimizing a surgical route, rehearsing a surgical procedure, etc. The simulation system comprises: an image acquisition device (101) acquiring medical image data of a vessel which is to be performed endovascular intervention surgical simulation on and tissues and organs surrounding the vessel, the medical image data being medical image data of a specific patient; a model establishing device (102) establishing a three-dimensional geometric model (501) of the vessel and the tissues and organs surrounding the vessel from the medical image data; a physical operative instrument (103) for a user to operate during the endovascular intervention surgical simulation, wherein the model establishing device (102) controls, according to the operation of the user on the physical operative instrument (103), a motion trajectory (502) of a three-dimensional model of the operative instrument in the three-dimensional geometric model (501) of the vessel; and a display (104) displaying the three-dimensional model (501) of the vessel and the tissues and organs surrounding the vessel, and the motion trajectory of the three-dimensional model of the operative instrument in the three-dimensional geometric model of the vessel.

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 results. 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 p...

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
