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

Embodiment 1

[0096] This embodiment provides a thoracoscopic-assisted coronary artery bypass grafting training model, which is mainly made by the following steps:

[0097] 1. Extraction:

[0098] 1. Take an adult pig and lay it flat on the table with the abdomen facing up. Use a long and pointed knife to cut the abdomen, and close to the anus to separate the rectum and urethra;

[0099] 2. Starting from the bladder level, the back side is close to the spine, and the two sides are close to the psoas minor and psoas major muscles. Use a sharp knife to separate the spine and muscles until the diaphragm level. Pay attention to protecting the ureter and kidney during the separation process according to the above requirements The left and right common iliac vessels will be severed 4cm below the aortic bifurcation;

[0100] 3. Cut off the diaphragm completely close to the abdominal wall, and pay attention to protecting the esophagus, trachea, thoracoabdominal aorta, and superior and inferior ven...

Embodiment 2

[0117]The difference between this example and Example 1 is that this example uses the whole set of viscera and its internal blood vessels of an adult sheep to make a thoracoscopic-assisted coronary artery bypass grafting training model, and the rest of the steps and operating parameters are the same as those of the implementation The same as in Example 1, a training model of thoracoscopic-assisted coronary artery bypass grafting was obtained.

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 ...
