The invention relates to the technical field of respiratory and critical instruments, in particular to a thoracic cavity puncture guiding and positioning device for a patient suffering from severe respiratory diseases.

Background

In clinical work of pulmonary department, thoracocentesis is a relatively common and convenient and simple diagnostic and therapeutic method. Such as: through examination, we find that the pleural cavity of the patient has effusion, and can extract liquid through thoracentesis, perform various examinations, and find the cause of the disease. If the effusion in the cavity is too much, the lung is pressed or the effusion is excessively long, fibrin in the effusion is easy to be organized to cause adhesion of two layers of pleura, thereby affecting the respiratory function of the lung, and then the effusion is also punctured and pumped out. If necessary, the medicine can be injected to achieve the purpose of treatment.

In the existing diagnosis and treatment thoracocentesis process, because the puncture needle needs to be hand-held for puncture, the puncture needle is difficult to fix, and when a patient is in fine adjustment of posture or slightly coughing due to pain discomfort or disease influence, the normal operation of puncture can be seriously influenced, and the puncture needle is not only influenced to puncture the thoracocentesis; and the needle body is easy to be dissociated and even the position is misaligned in drainage or air extraction, and the needle body is penetrated into thoracic organs to cause organic injury, so that the operation difficulty of the operation is increased for medical staff.
