Description

一种可回收穿刺锚 技术领域
本发明涉及一种可回收穿刺锚，属于医疗器械领域。
背景技术
目前，内镜手术在治疗一些疾病时，常常需要组织与组织的连接固定吻合，或者是组织的辅助固定，有利于手术的顺利开展。比如在内镜下做保胆取石手术、胃肠吻合手术、组织剥离手术时，常常需要吻合固定组织，目前市场上还没有可靠的器械解决。
内镜下保胆取石是有巨大意义的手术方法，可以通过内镜将胆囊结石取出，并且保留胆囊功能。这个手术目前遇到的最大问题是不能固定住胆囊，造成手术难度大，成功率低。目前还没有好的解决方案。
内镜下做病变组织剥离切除手术比较普遍，但最大的问题是组织无法固定或移动，造成手术时间长，难度大。

具体实施方式
下面结合附图对本发明做进一步详细描述：
如图1所示，一种可回收穿刺锚，包括固定器1、回收线2和推送丝3，所述固定器1为圆柱状结构，所述回收线2固定在固定器1的一端，所述推送丝3柔性连接在固定器1的中间段。
优选地，所述固定器1沿轴向开有通槽5，且所述推送丝3柔性连接在通槽5中，使得推送丝3在轴向时容纳在通槽5里，整个穿刺锚外径不过大。
优选地，所述固定器1的中间段沿径向设有穿线孔6，所述推送丝3穿过穿线孔6，且当需要使用多个穿刺锚时，只需将推送丝3按顺序一个接一个地 穿过各个穿刺锚的穿线孔6，从而实现连接多个穿刺锚。
优选地，所述固定器1沿轴向加工一凹平面7，且在凹平面侧加工一穿线凸块8，所述穿线凸块8沿轴向设有通孔，所述推送丝3穿过通孔，所述穿线凸块8与固定器1一体成型。
优选地，所述固定器1的一端或两端为球面结构4，固定器一端为球面结构一方面是为了安全，不锋利，另一方面是由于球面结构方便找中心，方便回收，且本发明中固定器的端部球面结构不仅限于一端。
优选地，所述固定器1采用棒材或管材加工。
优选地，所述推送丝3为硬质丝线，具有一定的推送强度，且在表面涂覆高分子材料涂层9，可以降低推送时的摩擦力，如图5所示。
优选地，所述推送丝3为软质丝线，与其他器械配套推送，本发明中利用其他器械配套推送属于常规技术手段，故而未加详述。
优选地，所述回收线2为软质线。
优选地，所述固定器1为硬质材料，有一定的刚性强度。
实施例1：
如图2所示，固定器1为圆柱状结构，且不仅限于一端为球面结构4，回收线2固定在固定器1的一端，在固定器1上沿轴向开设通槽5，推送丝3柔性连接在固定器1的中间段，且位于通槽5内，用于容纳推送丝3，使得固定器1与推送丝3成一直线时，不让外径变大，从而提升穿刺锚在穿刺针10的内孔孔道内的通过性。
实施例2：
如图3所示，在固定器1的中间段沿径向设有穿线孔6，推送丝3从穿线孔6中穿过，回收线2固定在固定器1的一端，固定器1不仅限于一端为球面结构4。此外，固定器1可采用棒材或管材加工。当需要使用多个穿刺锚时，只需将推送丝3按顺序一个接一个地穿过各个穿刺锚的穿线孔6，从而实现连接多个穿刺锚。
实施例3：
如图4所示，在固定器1上沿轴向加工一凹平面7，且在凹平面侧加工一穿线凸块8，穿线凸块(8)沿轴向设有通孔，推送丝3从通孔中穿过，所述穿线凸块8与固定器1一体成型。固定器1与推送丝3成一直线时，推动丝3收拢在凹平面7内，不让外径变大，提升穿刺锚在穿刺针10的内孔孔道内的通 过性。回收线2固定在固定器1的一端，且固定器1不仅限于一端为球面结构4。此外，固定器1可采用棒材或管材加工。
本发明的使用方法:
实施例1、2和3的使用方法基本相同。如图6所示，在内镜的引导下，内镜穿刺针(或者其他类似器械)穿刺组织到达目标位置，然后将穿刺锚的推送丝3与固定器1收为一直线(此时，实施例1中推送丝3位于固定器1的轴向通槽5内，实施例3中推送丝3收拢在凹平面7内)，然后如图7所示，利用推送丝3将固定器1从穿刺针10的内孔推送出内镜穿刺针头端(固定器1不连接回收线的一端先进入穿刺针的内孔)，随后固定器1自动与推送丝3成垂直状态，撤出内镜穿刺针，拉动推送丝3，可以将组织牵引移动，达到组织与组织的合拢作用，如图8所示。当然也可以单独移动目标组织，给手术治疗提供了方便的途径。手术完成后，拉动回收线2，固定器1自动与回收线2成一直线，从而撤出穿刺锚。
以上实施是对本发明优选实施方案进行描述，但本发明不限于此，在不脱离本发明的构思和工作原理下，本领域普通技术人员对本新型的技术方案和材料作出的各种变形和改进，均应在本发明的权利要求书确定的保护。
