An insert needle can be exactly inserted to thoracic cavity, so as to avoid manually keeping one gesture for a long time and reduce the labor intensity of medical staff; the practicability is strong.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pleural effusion drainage and puncture device for chest oncology. Background technique [0002] In thoracic oncology, thoracentesis is relatively common, and it is a convenient and simple method of diagnosis and treatment. When effusion is found in the patient's pleural cavity, the effusion can be extracted by thoracentesis for various examinations. If there is a lot of effusion in the cavity, which compresses the lungs or the effusion takes too long, the fibrinogen in it is easy to organize and two layers of pleural adhesions occur, which affects the respiratory function of the lungs. At this time, the patient should also be improved by drainage of the effusion. Breathing, if necessary, drugs can also be injected to achieve therapeutic purposes. [0003] Generally, before thoracentesis and drainage, the chest color Doppler ultrasound can be used for positioning first...

Problems solved by technology

[0004] At present, the puncture needle is inserted into the chest cavity manually. The specific operation method is: one of the hands of the medical staff clamps the needle with a hemostat, inserts it into the chest cavity, and continues to maintain this position. Follow-up operations can only be performed with The other hand is used to complete the follow-up operation, which makes the follow-up operation very difficult. If the operator is not experienced enough, if the puncture needle is fixed with one hand, it may be unstable, which may cause the puncture needle to slip out or the needle to shift, causing secondary injury to the patient.
