Abstract:
Thoracentesis is common in daily medical practice. During the operation, it is easy to cause complications such as re-expansion pulmonary edema, pulmonary hypotension, liver and spleen injury, pleural reaction, intercostal artery injury, pneumothorax, and so on. If the operator does not master procedures properly, it is easy to damage the thoracic organs. Therefore, the department of the general practice of the First Hospital of Jiaxing improved the puncture needle device based on thoracic puncture cannula, developed a new type of disposable thoracic puncture cannula, and obtained the National Utility Model Patent of China (patent number: ZL 2019 2 2112955.7). New type of disposable thoracic puncture cannula comprises a flexible puncture cannula, a steel needle, a limit structure, and a second bolt. In the process of puncture, the length of the puncture is limited by the limit structure. If the puncture force is too strong, the limit structure will prevent further penetration of the needle. The device is easy to use, flexible to operate, easy to master, and can reduce the risk of thoracentesis, which is worth of clinical promotion.
