PUNCTURING DEVICE AND ANCHORING DEVICE
(FR)
DISPOSITIF DE PERFORATION ET DISPOSITIF D'ANCRAGE
(ZH)
穿刺装置及锚定装置
Abstract:
(EN)
Disclosed are a puncturing device (100) and an anchoring device, the puncturing device (100) comprising: a puncturing needle (11), an inflatable anchoring balloon (22), and a catheter (21) which passes through a proximal end and distal end of the anchoring balloon (22), the puncturing needle (11) being movably accommodated within the catheter (21); in a filled state, a central area of an end portion of the distal end of the anchoring balloon (22) is depressed towards the proximal end to form a depressed area, and a distal end of the catheter (21) is located within the depressed area. The anchoring device comprises the anchoring balloon (22) and the catheter (21). The puncturing device (100) may improve the accuracy and success rate of puncturing, and after puncturing is complete, an expansion balloon (40) may be transported along a guide wire (300) to expand a puncturing opening by simply withdrawing the puncturing needle (11) and a push rod (13). In addition, since a distal end portion of an anchoring assembly (20) abuts against a punctured area, the possibility of the puncturing needle (11) continuing to advance after successful puncturing until the same pierces a membrane or a vascular wall on the opposite side is reduced.
(FR)
La présente invention concerne un dispositif de perforation (100) et un dispositif d'ancrage, le dispositif de perforation (100) comprenant : une aiguille de perforation (11), un ballonnet d'ancrage gonflable (22) et un cathéter (21) qui passe à travers une extrémité proximale et une extrémité distale du ballonnet d'ancrage (22), l'aiguille de perforation (11) étant logée de façon mobile à l'intérieur du cathéter (21) ; dans un état rempli, une zone centrale d'une partie d'extrémité de l'extrémité distale du ballonnet d'ancrage (22) est enfoncée vers l'extrémité proximale pour former une zone enfoncée, et une extrémité distale du cathéter (21) est située à l'intérieur de la zone enfoncée. Le dispositif d'ancrage comprend le ballonnet d'ancrage (22) et le cathéter (21). Le dispositif de perforation (100) peut améliorer la précision et le taux de réussite de la perforation, et après la perforation, un ballonnet d'expansion (40) peut être transporté le long d'un fil de guidage (300) pour dilater une ouverture de perforation en retirant simplement l'aiguille de perforation (11) et une tige de poussée (13). De plus, étant donné qu'une partie d'extrémité distale d'un ensemble d'ancrage (20) vient en butée contre une zone perforée, la possibilité que l'aiguille de perforation (11) continue à avancer après une perforation réussie jusqu'à ce qu’elle perce une membrane ou une paroi vasculaire sur le côté opposé est réduite.
(ZH)
一种穿刺装置(100)和一种锚定装置,穿刺装置(100)包括穿刺针(11)、可膨胀的锚定球囊(22),和贯穿锚定球囊(22)的近端和远端的导管(21),穿刺针(11)可动地收容于导管(21)内,在充盈状态下,锚定球囊(22)的远端端部的中心区向近端凹陷形成凹陷区,导管(21)的远端位于凹陷区内。锚定装置包括锚定球囊(22)和导管(21)。穿刺装置(100)可提高穿刺准确性及成功率,并且在穿刺结束后,只需后撤穿刺针(11)和推杆(13),即可沿着导丝(300)输送扩张球囊(40)对穿刺口扩张。另外,由于锚定组件(20)的远端部抵压被穿刺区域,减小穿刺针(11)在穿刺成功后继续前进至刺破对侧覆膜或血管壁的可能。
