Description

Technical Field

[0001] The invention relates to the technical field of thoracoscopic simulation training, and in particular to a thoracoscopic intraoperative bleeding treatment simulation training device and a thoracic cavity preparation method. Background Art

[0002] Video-assisted thoracoscopic surgery (Video-assisted thoracoscopic surgery) is a new minimally invasive thoracic surgery technique that uses modern camera technology and high-tech surgical instruments to complete complex intrathoracic surgeries through a chest wall cannula or tiny incision. In order to help medical staff better cope with unexpected accidents during thoracic surgery, a thoracoscopy model can be used for simulation training.

[0003] When the thoracoscopic intraoperative bleeding management simulation training device is in use, it is impossible to control the bleeding volume of different organs, resulting in the model being not realistic enough during the simulation training. At the same time, when the thoracoscopic intraoperative bleeding management simulation training device is in use, the chest model is usually a disposable item, which increases the cost of using the chest model. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies of the prior art, the present invention provides a thoracoscopic intraoperative bleeding treatment simulation training device and a thoracic cavity preparation method. Plasma is poured into a blood storage bottle for use, the solenoid valve is closed, and a micro-electric push rod is connected to an external power supply. The micro-electric push rod is started to push the airbag to contract and squeeze, thereby squeezing the blood in the blood storage bottle. The pressure strength in the blood storage bottle can be different according to the amount of bleeding of multiple models, so the flow rate and flow rate of the blood can be controlled. When medical staff are simulating thoracoscopic surgery, the solenoid valve can be opened so that the blood in the blood storage bottle can be poured into a designated position in the thoracic cavity model, so that the medical staff can simulate more realistically. Artificial skin with high self-repairing ability can be made by adding organic silica gel and polypropylene glycol materials. These materials will soften and flow when heated, and will solidify when cooled, which makes them stretchable and elastic like human skin and not easy to tear. In addition, by adding metal particles and conductive carbon to the material, it can be made magnetic, further enhancing its conductive properties and self-repairing ability, so that the simulated skin can recover quickly after being damaged.
