Technical field
The utility model is related to medical instruments field, more particularly to a kind of Lung neoplasm puncture localization needle.
Background technology
With the development of CT scan (Computed Tomography, CT) technology, clinically increasingly
More solitary pulmonary nodules (Solitary pulmonary nodule, SPN) are found, diagnosing and treating.For sub- centimetre
Lesser tubercle, video-assisted thoracoscope (Video-Assisted Thoracoscopic Surgery, VATS) lung bioplsy art are created due to it
Hinder the advantages that small, recovery is fast, is the prefered method of small pulmonary artery biopsy.However it is less than the SPN of 20mm for diameter, due in hand
Art can not be touched when detecting with hand, it is difficult to be accurately positioned, be greatly affected the success rate of VATS.Therefore, how right in the preoperative
It is the problem that urgent clinical needs solve that SPN, which carries out accurately positioning,.
Preoperative common localization method includes that CT guides metal hook positioning, injection methylene blue staining, Intraoperative ultrasound etc.,
These methods come with some shortcomings：Methylene blue is injected to the tubercle good positioning effect at pleura, but to small in pulmonary parenchyma
Tubercle location difficulty, and with the extension of time, dyestuff can be spread, cause to be difficult to recognize lesion in art；Intraoperative ultrasound is for touching
Touch less than tubercle it is advantageous, but require to confirm lesions position in art repeatedly, it is complicated for operation, time-consuming, to operator and equipment
It is required that high；Metal hook position success rate is high, few intercurrent disease, but buckle wire (Hook-wire) head end of Clinical practice at present
It is fixed on intrapulmonary in hook-shaped, but only there are one barbs for its end, the problems such as easily shifting, fall off, cause bleeding, pneumothorax.
