Description

一次性使用心脏及血管内异常通道封堵器 Disposable intravascular and cardiac abnormalities channel occluder

本实用新型涉及一种医用人体内管腔封堵器件,尤其是一种由高弹性形状记忆合金丝制成的单盘和双盘封堵器。 The present invention relates to a medical body lumen occlusion device, in particular made of a highly elastic shape memory alloy wires and double disc single disc occluder.

治疗动脉导管未闭等异常通道疾病时,通常采用手术,近十多年来,也采用介入技术,用封堵器进行封堵。 Treating patent ductus arteriosus path abnormality such diseases, surgery usually last ten years, also interventional technology, plugging occluder. 对封堵器的基本要求是:①在孔腔内固定可靠,防止反向退出;②支撑稳定不塌陷;③与周边接触紧密,不漏血。 Occluder basic requirements are: ① reliably fixed in the bore, preventing reverse exit; ② stable support does not collapse; ③ close contact with the periphery, not endoleak. 对于漏斗形孔腔通常采用单盘封堵器进行封堵,对于窗口形孔腔则通常采用双盘封堵器封堵。 Generally funnel-shaped bore for single disc occluder for closure, for the window are usually shaped bore Double Occluder. 现有的单盘封堵器结构如图A2-a,图A2-b所示,其柱体部分是平的。 Single disc occluder conventional structure shown in Figure A2-a, as shown in FIG A2-b, which cylindrical portion is flat. 现有的双盘封堵器结构如图B2-a,图B2-b所示,其柱体及双盘之间的腰部是平的,光滑的。 Double occluder conventional structure shown in FIG B2-a, as shown in FIG B2-b, and a waist between the double disc cartridge which is flat and smooth. 当用于如图A2-c,图B2-c所示的封堵孔腔时,平面柱体使其与腔壁的接触面积受到限制,从而使支撑力和防塌陷力均有限。 When used in FIG A2-c, when the closure shown in FIG bore B2-c, so that the contact area of ​​the cylinder plane of the cavity wall is restricted, so that the anti-collapse force and the supporting force are limited. 光滑的腰部难以适应不同壁厚的孔腔或不均匀壁厚的孔腔,从而对在孔腔内的紧密接触固定会有一定影响。 Smooth bore waist difficult to adapt to different wall thicknesses or uneven wall thickness of the bore, to fix will have some impact in close contact with the bore.

本实用新型的目的在于:提供一种一次性使用心脏及血管内异常通道单盘和双盘封堵器,使能增强与管腔的支撑力和防塌陷能力,增加在孔腔内的紧密接触固定,提高封堵性能和防反向退出力。 The object of the present invention: to provide a disposable intravascular and cardiac abnormalities single channel and double disc occluder plate, enabling to enhance the lumen and anti-collapse force of the supporting ability to increase the close contact with the bore fixed to improve the sealing performance and anti-reverse ejection force.

实现本实用新型目的的技术方案是:在一种一次性使用心脏及血管内异常通道单盘封堵器中,其柱体上部具有一个上盘,柱体及上盘均为可伸缩的网状结构,在该单盘封堵器的柱体外表面上有若干道环状突起,柱体的纵向表面呈波浪形。 Object of the present invention achieve technical solution: a cardiac and vascular abnormalities within a single channel tray disposable occluder In one, an upper portion having a cartridge on the disc, and the disc cartridge are strainable network structure, the single disc occluder outer surface of the cylinder has a plurality of annular projection channel, the longitudinal surface of the cylinder of wavy.

实现本实用新型目的的技术方案还可以是:在一种一次性使用心脏及血管内异常通道双盘封堵器中,其柱体上部和下部各具有一个上盘和一个下盘,柱体及上盘、下盘均为可伸缩的网状结构。 To achieve the purpose of the present invention may also be technical solution: a cardiac and vascular abnormalities within the channel disposable double disc occluder In one, its upper and lower portions of each cylinder having an upper plate and a lower plate, and the cylinder on the disc, the lower disc are scalable network structure. 在该双盘封堵器的柱体外表面有若干道环状突起,柱体的纵向表面呈波浪形。 There are several channels in the outer surface of the annular projection of the double disc occluder column, wavy longitudinal surface of the cylinder.

在该双盘封堵器的上盘及下盘之间的腰部可向内凹入,形成一圈向内叠入部分。 It may be recessed inwardly in the waist between the double disc occluder on the disc and the lower plate, forming a circle inwardly into overlapping portion.

由于采用上述技术方案,在单盘和双盘封堵器的柱体表面上制成若干道环状突起,与现有技术中柱体部分是平的相比,本实用新型与病患管腔的接触面积增大,从而增强了支撑力和防塌陷力,而且呈波浪形咬合,增加了在孔腔内的接触固定,提高了封堵性能和防反向退出力。 Since the above technical solution, on the surface of a single cylinder and double disc occluder plate made of a plurality of annular projection channel, compared with the prior art flat cylindrical portion, the present invention patients with a lumen the contact area increases, thereby enhancing the supporting force and anti-collapse force, and wavy nip, increasing the bore of the fixed contact, to improve the sealing performance and the anti-reverse ejection force. 在双盘封堵器的腰部再向内凹入一圈叠加部分,使之能通过上、下盘的适当向上、下张开,以适应变化的和不均匀的壁厚,从而更增加在孔腔内的紧密接触固定。 Double waist occluder concave inner circle superimposed portion again, so that through the appropriate lower plate upwardly, the lower opening, to accommodate variations in wall thickness and non-uniform, thereby further increasing the aperture fixed in close contact with the cavity.
