Embodiment Construction

[0016] see figure 1 and figure 2 , a modified pulmonary nodule puncture needle set is shown in the figure, including a puncture needle 10 with an inner hole and a positioning guide wire 20, and the tail of the puncture needle 10 is fixed on a puncture needle base 30. Before use, the positioning guide wire 20 is inserted into the inner hole of the puncture needle 10 from the end of the puncture needle base 30 . The positioning guide wire 20 has a positioning end 21 and a pushing end 22. After the positioning guide wire 20 is inserted into the inner hole of the puncture needle 10 from the end of the puncture needle base 30, the positioning end 21 of the positioning guide wire 20 is positioned at the end of the puncture needle 10. In the inner hole, the pushing end 22 exposes the puncture needle base 30, so that after the needle point 11 of the puncture needle 10 penetrates into the lesion, the positioning guide wire 20 is pushed into the lesion for positioning.

Abstract

The invention discloses an improved lung node puncture positioning needle assembly which comprises a puncture needle with an inner hole and a positioning guiding wire penetrating through the punctureneedle, a V-shaped barb is arranged at the positioning end of the positioning guiding wire, the end, opposite to the positioning end, of the positioning guiding wire is a push end, and a reinforcing part is arranged at the portion, close to the positioning end, of the positioning guiding wire. The assembly is characterized in that a bent part with the memorizing function is arranged at the portion, close to the positioning end, of the positioning guiding wire, the bent part deforms to be linear when the positioning guiding wire is inserted into the inner hole of the puncture needle, and the bent part recovers to be bent after the positioning guiding wire gets away from the inner hole of the puncture needle. When the V-shaped barb of the positioning end of the positioning guiding wire hooksthe focus of the disease, and after the puncture needle is pulled out, the V-shaped barb on the positioning guiding wire is matched with the bent part, the positioning guiding wire is stopped from moving forwards and backwards, and the probability that the positioning guiding wire is disengaged from the focus of the disease to be retracted into the chest wall or slide into the mediastinum is eradicated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an improved pulmonary nodule puncture positioning needle set. Background technique [0002] Small pulmonary nodules refer to solitary quasi-circular lesions in the lungs, less than 2 cm in diameter, without pneumonia and enlargement of local lymph nodes. In recent years, there have been more and more patients with small pulmonary nodules. The early diagnosis of pulmonary nodules is difficult, lacks clinical specificity, and has various imaging forms. It is difficult to determine benign and malignant, which often leads to misdiagnosis and delayed treatment. Clinically, surgical treatment is advocated for such patients, and good results have been achieved. Thoracoscopic pulmonary nodule resection is often used during surgical operations. Accurate positioning of small nodules often becomes the key to the success of the operation. Therefore, preoperative CT-guided positionin...
