The utility model discloses a disposable bolt removal basket, which comprises a catheter, a guide wire, a basket and a guide wire part of the bolt removal basket. The utility model is characterized in that the basket is conical and a small hole is arranged at the bottom for the guide wire to pass through; the opening of the basket is symmetrically provided with two lifting ears; the lifting ear and the side of the mesh mouth are integrally shaped, and the mesh wire at the intersection of the lifting ear basket is thicker than that at other parts. The mesh makes the mesh opening V-shaped; the top of the free side of the puller is connected with the guide wire part of the bolt basket, and the guide wire part of the bolt basket is symmetrically located in the middle of the basket; the guide wire part of the bolt basket passes through the straight end of the catheter and passes through the bend end of the catheter; the bolt basket can effectively filter blood, at the same time, it is easy to catch thrombus, has fewer times of bolt removal, and the bolt is clean. At the same time, it can keep the net basket in the process of capturing the thrombus without deformation, and has little trauma to the blood vessels. It can effectively reduce the complications such as incision infection, stenosis, hemorrhage and thrombosis caused by incision and suture.
【技术实现步骤摘要】
一种一次性使用取栓网篮
本使用新型涉及一种医疗器械,具体涉及一种一次性使用取栓网篮。
技术介绍
血栓是血流在心血管系统血管内面剥落处或修补处的表面所形成的血凝块,血栓随着血流方向流向远端血管,阻塞重要脏器的血液供应,例如脑、心脏或其他重要器官,这种栓可能导致脑梗塞、心肌梗塞、脑栓塞,肢体缺血、坏死等,严重者可能导致死亡,现在的工艺一般采用远端保护器来过滤并手术过程中脱落的斑块、血栓等栓子,远端保护器取栓的方法操作简单,对血管的伤害比较小,但是经常不能抓住血栓,需要进行多次取栓仍无法取净且术中操作复杂手术时间较长,或需要在抓捕时同时利用倒影导管进行抽吸,否则血栓会逃逸并阻塞远端血管。
技术实现思路
本技术的目的在于提供一种一次性使用取栓网篮,可以有效过滤血液,同时对于血栓的抓捕容易,取栓次数较少,且取栓干净,同时能够保持在捕获血栓的过程中网篮不会变形,对于血管的创伤极小,属于微创手术,有效减少因切开、缝合引起的切口感染、血管狭窄、出血、血栓形成等并发症,送达位置准确、容易,不需要反复调整导管及网篮位置。一种一次性使用取栓网篮,包括导管,导丝,网篮,取栓网篮导丝部;其特征 ...
【技术保护点】
