Technical Field

Background

At present, in the traditional preoperative CT-guided pulmonary nodule localization, a hook or a contrast agent is mostly adopted in the localization method to determine the position of a pulmonary nodule, and then corresponding cutting is performed; however, in practice, it has been found that such a positioning method has some disadvantages: firstly, the position positioned by the hook is easy to deviate, so that the position of a pulmonary nodule cannot be well determined; the large area of the lung nodules imaged by the contrast agent, which requires cutting a large area even if some small lung nodules are removed, may require removing the entire lung if there are many small lung nodules, and obviously, such a positioning method cannot be widely used in practical applications.

Disclosure of Invention

In order to achieve the purpose, the invention adopts the technical scheme that: a method of locating a pulmonary nodule, comprising the steps of:

s1, establishing a sealed negative pressure tunnel in the lung;

s2, enabling the argon-helium knife to enter the lung through the closed negative pressure tunnel;

s3, guiding argon-helium knife to puncture to a pulmonary nodule in the lung by utilizing a CT technology;

s4, after the argon-helium knife stays at the pulmonary nodule for a period of time, an ice ball is formed at the pulmonary nodule;

and S5, taking the ice ball as the positioning point of the lung nodule to carry out subsequent operation.

Further, after S4, the steps of S3-S4 may be repeated a plurality of times to form ice balls at a plurality of lung nodules.

Further, in S4, the temperature of the argon-helium knife is between-130 ℃ and-200 ℃.

Further, after S4, the argon-helium knife was drawn out from the closed negative pressure tunnel, and then methylene blue was introduced into the closed negative pressure tunnel, so that the ice ball turned blue.

Further, in S4, the argon helium knife is maintained at the lung nodule for a period of time between 20min and 30 min.

Due to the application of the technical scheme, compared with the prior art, the invention has the following advantages:

firstly, an ice ball formed by an ice skate consisting of an argon-helium knife at a pulmonary nodule has a certain ablation effect on the pulmonary nodule; for deeper lung nodules, the ablation process may be directly biopsied or the ablation/resection may be determined based on the results of the biopsy.

Secondly, the formed ice ball can be used as a positioning point for subsequent operations, so that lung nodules can be conveniently cut subsequently.

And the lung nodules positioned by the ice hockey are accurate in position, and redundant lung tissues cannot be cut off.

And fourthly, the lung contained by the ice ball can also be used as a specimen after the operation, thereby being convenient for the follow-up observation and treatment.

Fifthly, introducing methylene blue into the closed negative pressure tunnel to change the ice ball into blue, so that the ice ball is easier to identify and is convenient for subsequent treatment.
