Advantage.
For finding the patient of lung occupy-place, the Drug eluting stent under CT guidance has clear pathological diagnosis important
Value.However, there are the possibility that bleeding, pneumothorax occurs for the percutaneous biopsy of lung occupy-place.Pneumothorax can pass through postoperative chest after puncture
Portion's x ray photograph or CT examination find that accumulated gas in the visible puncture side thoracic cavity of read tablet, lungs are compressed in various degree, and patient is then
There is the asthma symptom uncomfortable in chest differed in weight, severe patient even needs urgent row closed drainage of thoracic cavity operation gas is discharged.
The reason of pneumothorax occurs after puncture is in the gap that cell taking gun and paracentesis trocar needle core are interleaved alternately with or puncture
During trochar is pulled out after the completion, air enters thoracic cavity along puncture trochar needle track.For the process that trochar is pulled out, mesh
Before there is clinician to invent the method that fluidity is withdrawn, i.e., while pulling out trochar, by casing, with syringe to intrapulmonary
A small amount of lidocaine injection is injected, to play the role of closing needle track.But there are still shortcomings for this method: one
Aspect increases the operating procedure of puncturing operation, and the injection scale of construction is difficult to control；On the other hand, cell taking gun and company are being taken out
Connect between syringe, equally exist a period of time gap can lead to air enter thoracic cavity cause pneumothorax.
