Coronary artery bypass transplantation training model and manufacturing method thereof

Abstract

The invention provides a thoracoscope-assisted coronary artery bypass transplantation training model and a manufacturing method thereof, and relates to the technical field of animal specimen models. The manufacturing method comprises the following steps: providing a whole set of internal organs of an animal, ligating superior vena cava, separating inferior vena cava, thoracic aorta and esophagus, inserting a first tube is inserted into the right atrium through the inferior vena cava, inserting a second tube to the right ventricle through the proximal end of the pulmonary artery, inserting a third tube to the left ventricle through the left auricle, connecting the second tube with the third tube, and inserting a fourth tube through the aorta to obtain the training model. The technical problems that a single isolated organ is poor in training effect, living animal training is high in cost and small in convenience, a box type simulator is small in training skill coverage range, and a 3D simulator is poor in simulation effect are solved. The technical effects that the animal organ combination model with the adjacent organs and the complete blood vessels is provided for the doctor, materials are convenient and low in cost, the doctor obtains real and convenient skill training, and the operation touch sense and force feedback are guaranteed are achieved.

Description

technical field [0001] The invention relates to the technical field of animal specimen models, in particular to a training model for coronary artery bypass grafting and a manufacturing method thereof. Background technique [0002] In a historical stage of surgery, surgeons mostly adopt the teaching mode of skill training on patients, but this training mode often brings huge medical risks, so in order to avoid such medical risks and truly master Surgical operation skills and various non-human surgical skill training modes emerged as the times require. [0003] At present, surgeons can use single animal organs purchased from the market for surgical training, or use live animal surgery for training, and others use virtual simulators composed of 3D animation and force feedback systems for surgical training. It is a simple simulation box using plastic, silica gel and other products as a training module for surgical training. [0004] However, when the operation training doctor ...

AI Technical Summary

Problems solved by technology

[0004] However, when the operation training doctor uses a single heart purchased from the market to carry out the anastomosis training of coronary artery grafting, the pulsation of the heart and blood vessels cannot be taken into account, so the coronary artery cannot be filled, so that it is difficult to ensure a simulated operation environment; while the operation training doctor When the training method of live animal surgery is adopted, a very specialized training site is required, and the cost of the site, cost, and labor are high, which makes it difficult for doctors to have training opportunities. At the same time, when using live animals for surgery At the same time, personnel often need to queue up to practice on different organs of animals, which greatly wastes the time of doctors, and the thorax structure of live animals and humans is not completely similar, and there will be certain differences between the two in actual operation; When surgical training doctors use virtual simulators composed of 3D animation and force feedback systems for surgical training, and when using simple simulation boxes made of plastic, silicone and other products as training modules for surgical training, the pictures and force feedback are similar to real operations. Large gap, so the training effect obtained is not ideal
