Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a visceral pleura scraping device. Background Art
[0002] As an important organ of the human body, the lungs play a crucial role in the human respiratory system. When pathological conditions occur in the lungs, they are generally divided into lung infections, acute respiratory distress syndrome, trauma or injuries, or lung tumors. When the first two types of lung injuries occur, the main treatment method is drug treatment. As for lung injuries caused by other reasons, the drug can only play an auxiliary role in helping the body recover.
[0003] The human lungs are covered and filled with pleura, and the pleura is a thin and smooth serous membrane. The visceral layer covering the surface of the lung is called the visceral pleura, which is closely combined with the lung parenchyma and folds into the lung fissure. The parietal pleura lining the inner surface of the thoracic cavity and both sides of the mediastinum. The two parts are folded and continued with each other at the root of the lung, enclosing two completely closed potential cavities on the left and right, called the pleural cavity. The cavity is under negative pressure, so the visceral and parietal pleura are closely attached. During breathing, the lungs can expand or contract with the movement of the chest wall and diaphragm. There is a little serous fluid in the pleural cavity, which can reduce the friction between the visceral and parietal pleura.
[0004] When trauma or injury is detected in the lungs, to accelerate the recovery of the human body, the core idea is first to stimulate the body's own self-healing potential. Create a new abrasion surface (bleeding point) on the visceral pleura near the lung trauma site, and then the abrasion surface is closely attached (the internal pressure of the lung itself can complete this). Through the strong healing ability of the visceral pleura and the healing ability of the lung organ itself, it can also assist drug treatment to accelerate the treatment of lung trauma or injury. Next, it is the creation of a new abrasion surface (bleeding point) on the visceral pleura. It should neither be too heavy to cause perforation of the visceral pleura and lead to other unknown risks, nor too light to fail to scrape the visceral pleura and result in no obvious effect. Therefore, a special scraping device is needed to assist the doctor to complete this professional surgical operation. And to avoid introducing new traumas, mature operation procedures such as thoracoscopic and laparoscopic minimally invasive surgeries are used to complete this operation. For this reason, the inventor designed a visceral pleura scraping device. Content of the Utility Model
