Improved type lung node puncturing positioning needle external member

Abstract

The invention discloses an improved type lung node puncturing positioning needle external member, and relates to the technical field of puncturing positioning needles. According to the improved type lung node puncturing positioning needle external member disclosed by the invention, a puncturing external needle is connected with a base part through a connecting member; a puncturing internal needleis connected to the inner part of the puncturing external needle in a sleeving manner; a first groove channel is formed in the periphery side of the puncturing external needle; a fifth channel is formed in the periphery side of the puncturing internal needle; a fourth channel is formed in the periphery side of the base part; a positioning sleeve is connected to the tail of a positioning guide wirein the sleeving manner; and an adjusting spiral coil is connected to the positioning sleeve through threads. According to the improved type lung node puncturing positioning needle external member disclosed by the invention, the positioning guide wire is fixed by the positioning sleeve, the positioning guide wire and the puncturing internal needle are avoided by the third channel and the fourth channel, the base part is disassembled, the positioning guide wire is avoided by the first channel, and the puncturing positioning needle is drawn out, so that the moving of the positioning guide wire during and after an operation is greatly reduced; the positioning sleeve is manufactured of antibacterial plastic; a lattice protrusion is arranged on the inner wall of a second circular hole; and an attaching edge is in the shape of a trumpet, and is manufactured of silicone rubber, so that the positioning sleeve can be effectively attached to the skin of a patient, the risk of an allergic reaction is reduced, and the comfort degree is improved.

Description

Technical field [0001] The invention belongs to the technical field of puncture positioning needles, and particularly relates to an improved pulmonary nodule puncture positioning needle kit. Background technique [0002] Pulmonary nodule is a multi-system and multi-organ granulomatous disease of unknown etiology, which often invades lungs, bilateral hilar lymph nodes, eyes, skin and other organs. Sarcoid granulomas can be seen as skin-like cells on tissue sections Gather. Video-assisted thoracoscopic surgery is mainly used in clinical diagnosis and treatment. This operation is a minimally invasive operation. However, once the lung nodules are far away from the pleura or are too small in diameter, it is difficult to accurately locate them. This will not only increase the difficulty of the operation, but also It will cause a small number of patients to undergo conversion thoracotomy, which will adversely affect the patient's postoperative recovery.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an improved pulmonary nodule puncture positioning needle set, by setting a combined puncture outer needle, base, sealing piece, and puncture inner needle, and using the connecting piece, sealing piece, and positioning sleeve together, it is convenient to puncture. The positioning guide wire is fixed, and the influence on the positioning guide wire is reduced during the needle removal process, which solves the problem that the existing positioning guide wire is easy to shift during and after the puncture operation and affects the operation
