Title
(EN) ULTRASONIC BIOPSY NEEDLE
(FR) AIGUILLE À BIOPSIE ULTRASONORE
(JA) 超音波生検針
Abstract
(EN)
This ultrasonic biopsy needle comprises: a sheath inserted into a channel in an ultrasonic endoscope; a needle tube retractably inserted into this sheath; and an operation section connected to a base end of the sheath, for advancing and retracting the needle tube. The sheath has an extension-suppressing section positioned further on the tip side than a curved section base end of the ultrasonic endoscope, in a state in which the tip of the sheath is positioned within the field of view of an optical imaging mechanism for the ultrasonic endoscope. The extension-suppressing section: comprises a metal coil; has a ratio between the coil outer diameter and the channel inner diameter of 1.0:0.84-1.0:0.96; has an initial tensile strength for the coil of at least 2.0 [N]; and suppresses the extension of the sheath in conjunction with the advancing/retreating of the needle tube.

L'aiguille à biopsie ultrasonore de l'invention est équipée : d'une gaine insérée dans un canal d'un endoscope ultrasonore ; d'un tube d'aiguille inséré de manière à autoriser son avancée et son recul dans ladite gaine ; et d'une partie manipulation connectée à une extrémité de base de ladite gaine, et manipulant en avancée et en recul ledit tube d'aiguille. Ladite gaine possède une partie empêchant l'étirement positionnée côté extrémité avant dudit endoscope ultrasonore par rapport à l'extrémité de base d'une partie courbe, dans un état dans lequel l'extrémité avant de ladite gaine est positionnée à l'intérieur du champ visuel d'un mécanisme d'imagerie optique dudit endoscope ultrasonore. Ladite partie empêchant l'étirement est constituée d'une bobine métallique. Le rapport du diamètre externe de ladite bobine vis-à-vis du diamètre interne dudit canal, est compris dans une plage de 1,0:0,84 à 1,0:0,96. La force de traction initiale de ladite bobine est supérieure ou égale à 2,0[N]. L'étirement de la gaine du fait de l'avancée et du recul dudit tube d'aiguille, est empêché.
