Abstract

A temporary closure device for heart defects comprises a disc-like net rack, wherein the disc-like net rack is integrally formed by weaving fine wires, the fine wires form a closure head in the middle of the bottom of the disc-like net rack, a connecting part is fixed at the tail end of the closure head, and the surface of the disc-like net rack is covered with a flow resisting film; the height of the disc-like net rack is 2-3 mm. After the temporary closure device is conveyed to a defect position, the disc-like net rack is unfolded and enabled to be located on the left side of the defect position, a steel conveying cable is pulled to enable the disc-like net rack to be tightly attached to the left side of the defect position, and the defect position is temporarily closed; then, physiological indexes of a patient can be tested. After a test ends, the steel conveying cable is pulled to contract the disc-like net rack. The disc-like net rack is temporarily closed in the defect position instead of being tightly clamped in the defect position, after the steel conveying cable is pulled, the disc-like net rack enters a long conveying sheath through the closure head, and picking is facilitated.

Description

心脏缺损临时闭合器 Temporary closure heart defects

技术领域 FIELD

[0001]本发明涉及医疗器械领域,尤其是心脏缺损临时闭合器。 [0001] The present invention relates to the field of medical devices, particularly heart defects temporary closure.

背景技术 Background technique

[0002]先天性动脉导管未闭和房、室间隔缺损,是几种常见的非复杂性先天性心脏畸形,随着近几年经皮介入治疗技术的发展和成熟,以及植入材料的改进,应用经皮导管介入封堵治疗此类非复杂性的先天性心脏病的患者越来越多。 [0002] Congenital patent ductus arteriosus and atrial, ventricular septal defect, is uncomplicated several common congenital heart, as in recent years, percutaneous interventional therapy development and maturation, as well as improved implant material , patients with percutaneous catheter occlusion of such non-complex congenital heart disease is increasing.

[0003]现有的心脏缺损封堵器,采用超弹性的镍钛合金编制成的自膨性双盘结构,双盘结构内附高分子生物薄膜,网状结构内部填充有聚酯涤纶或聚四氟乙烯。 [0003] Existing cardiac defect occluder, using double-disc structure of the self-expanding superelastic Nitinol prepared into, double disc structure enclosing a biological polymer film mesh structure filled inside or poly Polyester tetrafluoroethylene. 在放置时,根据术前超声心动图检查选择合适大小的心脏缺损封堵器。 When placing, according to the preoperative echocardiography select an appropriate size defect occluder heart. 先将输送长鞘沿动脉血管通道放到缺损位置,接着在体外将心脏缺损封堵器与输送钢缆装配好,输送钢缆沿输送长鞘将心脏缺损封堵器推送缺损位置。 First conveyance path length of the sheath into the artery along the defect site, and then in vitro heart defect occluder and the delivery cable is assembled, cable transport along a conveying length of the sheath to push the defect occluder heart defect sites. 撤回输送长鞘并展开右心房盘面,使右心房盘面处于缺损处的左侦L将输送钢缆向后拉动约5〜10厘米,展开左心房盘面,使左心房盘面处于缺损处的左侧,使双盘结构夹紧在缺损位置的两侧,实现封堵缺损。 Withdrawal of the delivery sheath and expand length disk right atrium, the right atrium so that the disk is left L defect investigation of the delivery cable is pulled rearwardly approximately 5 to 10 cm, the disk to expand the left atrium, the left atrium disk on the left side of the defect, Double structure so that both sides of the defect in the clamped position, to achieve closure of defect. 由于不同病患对异物的排斥反应不同,一些病患在放置心脏封堵器后会出现生理测试数据变差,进而引起死亡的现象。 Because different patients rejection of foreign matter, and some patients after implantation of a cardiac occluder experience physical test data deteriorate, thereby causing the phenomenon of death. 但是,上述心脏封堵器的双盘结构与缺损位置结合紧密,在其固定后难以摘取下来,导致手术的风险性较高。 However, in the double-disc occluder heart defect structure and tightly binding position, removal is difficult after fixed down, leading to a higher risk surgery.

发明内容 SUMMARY

[0004]本发明的目的是提供心脏缺损临时闭合器,方便放置与摘取,用于测试病患是否适合关闭心脏的缺损,包括房间隔缺损、室间隔缺损、动脉导管未闭。 [0004] The object of the present invention is to provide a temporary closure of heart defects, to facilitate placement and removal, is suitable for testing a patient off a heart defects, including atrial septal defect, ventricular septal defect, patent ductus arteriosus.

[0005]为了达到上述目的,本发明提供如下技术方案: [0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] 心脏缺损临时闭合器,包括盘状网架,所述盘状网架由细丝编织形成一体,所述细丝在所述盘状网架的底部中央形成封头,所述封头的末端固定连接件,所述盘状网架的表面覆盖阻流膜。 [0006] Heart defects temporary closure, comprising a disc-shaped grid, the grid by a disk-like formed integrally woven filaments, the filament is formed at the center of the bottom head of the disk-shaped grid, the head fixed connection end surface of the disk-shaped baffle grid covering film. 细丝编织成盘状网架后,在盘状网架的底部中央固定形成封头。 After the filaments woven into a disc-shaped grid, at the center of the bottom disk-shaped grid is fixed forming head. 封头固定连接件,输送钢缆与连接件连接。 Head member is fixedly connected to the conveying cable is connected to the connecting member. 通过输送钢缆将本发明输送至缺损位置后,展开盘状网架,使盘状网架处于缺损处的左侧,并拉动输送钢缆,使盘状网架贴紧缺损位置,使本发明对缺损位置进行临时封堵。 After delivery by the cable of the present invention to a defect in the transport position, the disc-shaped expanded grid, so that the disk-shaped grid on the left side of the defect, and the delivery cable is pulled, so that the defect position close contact with the disc-shaped grid, of the present invention temporary closure of the defect location. 此时对病患进行的生理指标测试。 At this point physiological indices of patients were tested. 如果在测试时间内,生理指标正常,则说明该病患适宜装上现有的封堵器或者进行外科开胸补片修补;如果生理指标异常,则说明该病患不适用封堵器或进行外科开胸补片修补。 If the test period, normal physiological parameters, indicates that the patient is fitted with a suitable conventional open heart surgical obturator or patch repair; if physiological abnormalities, it indicates that the patient does not apply or occluder chest surgical repair patch. 测试结束后,拉动输送钢缆,将盘状网架回收至输送长鞘内,方便将本发明摘取。 After the test, the transport cable is pulled, the disk-shaped grid recycled to transport long intrathecal, facilitate the removal of the present invention.
