Abstract

The invention discloses a thrombus removing device. The thrombus removing device comprises a meshed self-expanded stent and core threads, and the stent with an open near end and a closed far end is cylindrical in an expanded state. When the thrombus removing device is in operation, the stent penetrates the interior of a thrombus to deliver the thrombus to the far end, after an initial blood circulation passage is established, the stent is released to the inner wall of a thrombus region, and radial supporting of the stent forms radial extruding and cutting of a thrombus layer to realize thrombolysis of a soft thrombus layer to expand the passage in a short period by the aid of blood, and rectangular mesh structures similar to large thrombi in size can realize effective insertion and nesting of the large thrombi. Due to spiral distribution of the mesh structures around the stent, exhaustive capture of the large thrombi in random distribution is guaranteed, and the thrombi are caught by the meshes of the stent and brought outside. Since the thrombi are uniformly distributed on axial meshes of the stent by inserting and hanging instead of being accumulated at the far end of the stent, injuries of vessel walls in recovery are reduced. Generated thrombus fragments enter the stent through an opening of the near end and collected by the closed far end.

[0026]由于自膨胀式的支架为由镍钛超弹合金薄壁管经过激光精密雕刻制成的超弹性支架,因此,可说网孔的网线为镍钛超弹合金薄壁管,本申请中将镍钛超弹合金薄壁的壁厚设置为0.1〜0.4mm。 [0026] Because self-expanding stents by a superelastic nickel-titanium superelastic alloy thin-walled tubes stents made through precision laser engraving, thus, can be said to mesh cable superelastic nickel-titanium alloy thin-walled tubes, this application nickel-titanium superelastic alloy in the thin wall thickness to 0.1~0.4mm. 本申请只是提供了一种镍钛超弹合金薄壁的具体尺寸,在实际中可根据需要根据血栓6存在的血管5的直径以及血栓6大小进行设定,且均在保护范围内。 The present application provides only a thin alloy superelastic nickel titanium particular size, it can be set according to the presence of thrombus in the blood vessel diameter and 6 6 5 Size of thrombus needed in practice, and are within the scope of protection.

[0027]优选的实施例中,将支架2膨胀状态的直径设置为2〜6mm,长度为10〜60mm。 [0027] In a preferred embodiment, the diameter of the stent in the expanded state is set to 2 2~6mm, length 10~60mm. 由于该支架2为自膨胀式支架,在使用过程中,该支架2能够沿轴向拉直成线型,以方便支架2进入血管5内,并进入血栓6远端,然后打开支架2,并在收回支架2的过程中,使血栓6进入支架2,实现血栓6的取出。 As the holder 2 is a self-expanding stents, during use, the stent 2 can be straightened into a linear axial direction, to facilitate the stent 2 into the blood vessels 5 and 6 into the distal end of the thrombus, and then open the holder 2, and in the process of recovery of the holder 2, the holder 2 into the thrombus 6, 6 achieve the thrombus removed. 血栓取出装置递送至血栓6远端,回撤芯丝4,带动支架2移动,支架2上的网孔切割血栓6,血栓6将附着在网孔上被拉入导管并撤出体外。 Thrombus retrieval device 6 is delivered to the distal end of the thrombus, retracement core wire 4, driven holder 2 is moved, the mesh stent thrombosis 2 cut 6, 6 thrombi adhering to the mesh is pulled into the catheter and the withdrawal vitro.

[0028]进一步的实施例中,为了便于使用者在手术过程中确定支架2的位置,本申请公开的血栓取出装置还包括设置在支架2远端,且能够被X光照射到的第一标示物I。 [0028] In a further embodiment, in order to facilitate the user to determine the position of the stent during the procedure 2, the present application discloses a thrombus retrieval device further comprises a holder disposed at the distal end 2, and can be irradiated with the light first indicator X was I. 具体的,该第一标示物I通过激光焊固定在支架2端部。 Specifically, the first marker I welded end bracket 2 is fixed by a laser.

[0029]更进一步的实施例中,该血栓取出装置还包括设置在支架2近端,且能够被X光照射到的第二标示物3。 [0029] In a further embodiment, the thrombus retrieval device 2 further comprises a proximal stent, and can be irradiated with the light of the second X marker 3. 在操作过程中,将血栓取出装置伸入血管5内部后,通过X光照射可显示第一标示物I和第二标示物3的位置,从而方便对支架2确定位置,提高操作的准确性并能够缩短手术时间。 In operation, after the thrombus retrieval device 5 projects into the interior of the blood vessel, may be displayed by X-ray irradiation position of the first marker and the second marker I 3, to facilitate determination of the position of the stent 2, and to improve the accuracy of operation It can shorten the operation time.

[0030]本申请中公开的第一标示物I为铂金管、铂合金管、金合金管或钨管,并同时将第二标示物3设置为铂金管、铂合金管、金合金管或钨管。 [0030] The present application is disclosed in a first marker I is a platinum tube, a platinum alloy tube, gold alloy tube or a tungsten tube, while the second marker 3 is set to platinum tube, a platinum alloy tube, gold alloy tube or tungsten tube. 生产者可根据不同的需要选择不同材质的标示物,只要能够保证能够被X光照射到以对支架2进行定位即可。 Producers can select a different marker materials according to different needs, it can be guaranteed as long as light is irradiated to X of the stent 2 can be positioned.
