Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a surgical drainage device. Background Art

[0002] Pleural effusion is a common clinical symptom characterized by pathological fluid accumulation in the pleural cavity. The pleural cavity is a potential gap between the visceral and parietal pleura. There is 5 to 15 ml of fluid in the pleural cavity of a normal person, which acts as a lubricant during respiratory movement. Fluid is formed and absorbed in the pleural cavity every day. Pleural effusion can occur if any reason causes increased production or decreased absorption of fluid in the pleural cavity. According to its occurrence mechanism, it can be divided into two types: transudative pleural effusion and exudative pleural effusion. The direct treatment for pleural effusion is to use a drainage tube to drain the effusion.

[0003] During thoracic drainage surgery, a puncture needle needs to be inserted into the patient's chest cavity through a surgical incision to suck out the accumulated fluid. Most existing drainage devices require medical staff to hold the device in hand for puncture, and the device must be held in hand throughout the drainage process. Medical staff's arms are prone to fatigue when holding the device for a long time, which may cause the medical staff's arms to tremble, causing the puncture needle to shake. The rigid puncture needle may injure the patient when shaking, and there is a risk of expanding the wound. Therefore, a surgical drainage device is needed. Utility Model Content
