About

In the early stage of the study, the CT-guided micro-coil locating method for pulmonary small nodules was optimized. This study will use a single set of target values non-randomized controlled trials to evaluate the safety and effectiveness of the optimized pre-loaded micro-coil locating method in pulmonary small nodules.

Full description

A series of optimization and improvement measures were tried for the complications of the CT-guided micro-coil locating method. After discussion, the method of micro-coil pre-loaded in the puncture needle and sealed first, and then for subsequent locating has more advantageous. The method avoids the direct penetration of the puncture needle into the atmosphere during operation, and the operation is simpler. In vitro tests of isolated lung specimens and pre-tests of 9 clinical patients were carried out. The results showed that this method not only reduced the number of operators on site, but also had the tendency to shorten the operation time, reduce the incidence of pneumothorax, and improve the success rate. However, there is currently no rigorous scientific research to provide objective evidence for its safety and effectiveness.

Therefore, this study intends to use a single set of target values non-randomized controlled trials to evaluate the safety and effectiveness of the optimized pre-loaded micro-coil locating method in pulmonary small nodules.
