Description

Notch-type lung nodule positioning puncture needle
Technical Field
The utility model relates to a medical puncture positioning apparatus technical field especially relates to a notch type lung nodule location pjncture needle.
Background
The morbidity and mortality of lung cancer have increased year by year, and lung cancer accounts for the first death of malignant tumors by the end of the 20 th century. The five-year survival rate of lung cancer is only 15%, but if some early lung cancer can be discovered and treated early, the five-year survival rate can reach 60-80%. With the development of imaging technology and the popularization of routine physical examination, more and more pulmonary nodules with unknown properties are detected. At present, full thoracoscopic surgery is the main means for diagnosis and treatment of pulmonary nodules, but the difficulty of the surgery is increased due to certain difficulty in accurate positioning of the pulmonary nodules in the surgery.
The pulmonary nodules (SPN) are the first imaging manifestation of most early lung cancers, and the problem of clinical qualitative diagnosis is becoming more and more prominent. At present, there are various methods for locating pulmonary nodules before thoracoscope surgery, the most common method is location by a steel wire with a hook, but the problems that a locating needle is easy to fall off, pneumothorax is easy to form after puncture, and the like exist. The hooked steel wire is positioned without a needle point and a barb, and is difficult to pull back and pierce in the operation process, sometimes loosened, and the difficulty is increased for the operation process of a doctor. And once the hook is not firm, the position is not accurate, the operation time is increased, and even the operation fails.
In the prior art, the depth of an anchoring positioning needle is indicated by different colors at the far end of a positioning line, so that the depth of a focus is judged. However, the use of color to indicate lesion depth provides an obstacle to the work of determining lesion depth for operators who do not know the specific distribution position of color. Secondly, in order to improve the positioning accuracy, the number of color areas on the positioning line must be increased, which puts higher requirements on the acquaintance of the operator on the color distribution; but if the number of colors on the positioning line is reduced, the positioning accuracy will be reduced. How to grasp the balance between precision and difficulty in use is a difficult problem, and therefore, a solution is needed to solve the problem.
There is a lung nodule location pjncture needle and has laid at least a set of marker along its axial on adopting the location line, the marker is including a plurality of barb group along the axial distribution of location line. But has the following disadvantages: during assembly, the positioning wire penetrates through the puncture tube, the barbs on the positioning wire are easy to rub and fall off from the puncture tube, and an operator cannot judge the depth of a focus by counting the number of the barbs. In addition, the positioning line is provided with a plurality of barb groups which are distributed along the axial direction of the positioning line, the barbs have certain height from the positioning line, the positioning line penetrates through a puncture tube with a small inner diameter, the diameter of the positioning line with the barbs is limited, the strength of the positioning line is influenced, and the positioning line is easy to break during operation, so that the success rate of the operation is influenced.
