Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] refer to Figure 1-5 , this embodiment provides a needle tool for puncture and positioning of pulmonary nodules, including a stylet 1 and a cannula 2, the cannula 2 is a hollow cavity with openings at both ends, and the stylet 1 One end is provided with a hook-shaped structure 11, the hook-shaped structure 11 is bound in the sleeve 2 to realize contraction, and the other end of the stylet 1 extends out of the sleeve 2; in this embodiment, the hook-shaped structure 11 is a double-hook structure , also can be single hook or multi-hook as required, no longer repeat. The stylet 1 is stainless steel wire or titanium alloy wire.

[0031] A partition 21 is arranged in the hollow cavity to divide the hollow cavity into two chambers along the axis direction, and the stylet 1 passes through the partition 21; the sleeve 2 also includes an infusio...

Abstract

The invention provides a lung nodular puncture locating needle comprising a stylet and a sleeve; the sleeve is a hollow cavity with two opening ends; one end of the stylet is provided with a hook structure constrained in the sleeve to realize contraction; the other end of the stylet extends outside the sleeve; a separator is arranged in the hollow cavity so as to divide the hollow cavity into two chambers along the axis direction; the stylet penetrates the separator; the sleeve also comprises a transfusion tube; the transfusion tube is connected to the chamber, far away from the hook structure, of the hollow cavity through the side wall of the sleeve. The lung nodular puncture locating needle cannot have pneumothorax problems in the puncturing process, and can inject dye in the nodular position for indexing.

Description

technical field [0001] The invention relates to the field of puncture positioning, in particular to a needle used for puncture positioning of pulmonary nodules. Background technique [0002] Regarding the diagnosis and treatment of small pulmonary nodules, since the mid-1990s, domestic and foreign literature have successively reported a variety of preoperative and / or intraoperative lesion localization methods, such as injection of methylene blue, iodized oil, and intraoperative application of ultrasound. However, these methods have their disadvantages: injection of methylene blue into the lung parenchyma around the nodules may cause dye staining in the pleura and the pleural cavity, making it difficult for video-assisted thoracoscopic (VATS) operators to identify specific lesions location; preoperative CT-guided injection of iodized oil and other contrast agent positioning method also has the disadvantage of contrast agent diffusion, and requires real-time CT examination equ...
