Description

打结器 技术领域
本发明涉及医疗器械的技术领域，具体而言，涉及一种打结器。
背景技术
近些年来，随着手术器械及心脏外科手术技术的发展，微创手术已成为各个外科学科发展的热点方向。微创术具有切口小、恢复快的特点，同时要求术者在微创手术环境中，实现简单、快速的术后缝合和打结操作。临床上所用的打结方法有手法打结和器械打结两种。
现有的手术用打结器一般通过冲剪夹使得夹紧件发生塑性形变来夹紧缝合线，然后通过切割刀或剪切刀切断缝合线。该种切割方式存在的缺陷是：使用切割刀切断时，一是要求切割刀具有比较高的锋利度，一般材质的切割刀的刀刃容易受到损坏，二是缝合线要求处于绷紧状态中，松弛的缝合线，刀片输送过去不易切断；而使用剪切刀时，虽然改进了刀片不易切断松弛的缝合线，并降低对刀刃的锋利度要求，但是剪切刀的把手通过弹性件撑开，保持刀头部分张开，然后把手在传送杆的挤压下闭合剪切刀进而剪断缝合线。在使用过程中由于空间的限制弹性件会出现工作不稳定的问题。
发明内容
本发明的主要目的在于提供一种打结器，以解决现有技术中的打结器的剪切刀在切断缝合线时不稳定的问题。
为了实现上述目的，本发明提供了一种打结器，包括：传动结构；冲剪夹，冲剪夹的夹口具有打开状态的第一位置，以及受传动结构驱动而处于冲压的第二位置；剪刀，剪刀具有受传动结构驱动打开状态的第一位置，以及受传动结构驱动而处于剪切状态的第二位置；剪刀的第二位置和冲剪夹的第二位置同步。
进一步地，剪刀的第一端与传动结构相配合，剪刀的刀刃位于剪刀的第二端。
进一步地，剪刀包括第一剪刀臂和第二剪刀臂，第一剪刀臂和第二剪刀臂的中部通过枢转轴相连，传动结构与第一剪刀臂的第一端和第二剪刀臂的第一端相配合，第一剪刀臂的第一端和第二剪刀臂的第二端相靠近时，第一剪刀臂的第二端和第二剪刀臂相靠近；或者第一剪刀臂的第一端和第二剪刀臂第二剪刀臂的第一端相连，并形成枢转轴。
进一步地，剪刀位于冲剪夹的一侧，并与冲剪夹相邻设置。
进一步地，传动结构包括传送杆，传送杆的第一端与冲剪夹和剪刀均相配合。
进一步地，传送杆的第一端的第一侧部具有与剪刀相配合的剪刀臂孔，剪刀的第一端位于剪刀臂孔内。
进一步地，剪刀的第一剪刀臂和第二剪刀臂中部具有枢转轴时，剪刀臂孔的具体结构包括第一剪刀臂孔和第二剪刀臂孔，剪刀的第一臂位于第一剪刀臂孔内，剪刀的第二臂位于第二剪刀臂孔内。
进一步地，传送杆的第一端的第二侧部具有与冲剪夹相配合冲剪夹抵压板。
进一步地，打结器还包括手柄和套管，套管的第一端与手柄相连，剪刀和冲剪夹位于套管的第二端，传动杆位于套管内。
进一步地，打结器还包括驱动部，驱动部为设置在手柄处的手动驱动部；或者驱动部为设置在手柄处的自动驱动部。
应用本发明的技术方案，当对缝合线进行打结的时候，打结器的传动结构驱动冲剪夹冲压夹紧件，进而实现对缝合线的打结，与此同步的是，传动结构驱动剪刀处于剪切状态，这样使得剪刀可以将打结好的缝合线剪断。剪刀受传动结构的驱动处于打开状态和剪切状态，这样的结构稳定可靠。本发明的技术方案有效地解决了现有技术中的打结器的剪切刀在切断缝合线时不稳定的问题。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
如图1至图4所示，本实施例的打结器包括：传动结构10、冲剪夹20和剪刀30。冲剪夹20的夹口具有打开状态的第一位置，以及受传动结构10驱动而处于冲压的第二位置。剪刀30具有受传动结构10驱动打开状态的第一位置，以及受传动结构10驱动而处于剪切状态的第二位置。剪刀30的第二位置和冲剪夹20的第二位置同步。
应用本实施例的技术方案，当对缝合线进行打结的时候，打结器的传动结构10驱动冲剪夹20冲压夹紧件100，进而实现对缝合线的打结，与此同步的是，传动结构10驱动剪刀30。处于剪切状态，这样使得剪刀30可以将打结好的缝合线剪断。剪刀30受传动结构10的驱动处于打开状态和剪切状态，这样的结构稳定可靠。本实施例的技术方案有效地解决了现有技术中的打结器的剪切刀在切断缝合线时不稳定的问题。
如图3所述，在本实施例的技术方案中，剪刀30的第一端与传动结构10相配合，剪刀30的刀刃位于剪刀30的第二端。上述结构的剪刀加工成本较低，使用方便。需要说明的是，此处的剪刀30的刀刃位于剪刀30的第二端，并不单单仅指端部，可以为剪刀30的第二端向剪刀30的第一端之间的部分区域，例如图3中枢转轴31向所属剪刀30的第二端均为刀刃，也可以为部分刀刃。
如图3和图4所示，在本实施例的技术方案中，剪刀30包括第一剪刀臂和第二剪刀臂，第一剪刀臂和第二剪刀臂的中部通过枢转轴31相连，传动结构10与第一剪刀臂的第一端和第二剪刀臂的第一端相配合，第一剪刀臂的第一端和第二剪刀臂的第二端相靠近时，第一剪刀臂的第二端和第二剪刀臂相靠近。上述结构加工成本较低，安装容易，操作方便。或者，剪刀30的结构也可以为第一剪刀臂的第一端和第二剪刀臂第二剪刀臂的第一端相连，并形成枢转轴31。
如图1和图2所示，在本实施例的技术方案中，剪刀30位于冲剪夹20的一侧，并与冲剪夹20相邻设置。这样剪刀30和冲剪夹20之间的距离较短，即缝合线预留的长度较短。当夹紧件100夹紧缝合线打结完毕后，缝合线从夹紧件100留出的缝合线即是冲剪夹20至剪刀30的距离。具体地，冲剪夹20在左侧，剪刀30在冲剪夹20的右侧。
如图1和图2所示，在本实施例的技术方案中，传动结构10包括传送杆，传送杆的第一端与冲剪夹20和剪刀30均相配合。上述结构加工成本较低。冲剪夹20包括相对设置的两个夹臂，传送杆的第一端通过冲压夹臂使得冲剪夹20冲压夹紧件100，进行打结。具体地，传送杆的第一端的第一侧部具有与剪刀30相配合的剪刀臂孔11，剪刀30的第一端位于剪刀臂孔11内。上述结构紧凑，使得冲压和剪切通过同一根传送杆即可完成。剪刀30的第一剪刀臂和第二剪刀臂中部具有枢转轴时，剪刀臂孔11的具体结构包括第一剪刀臂孔和第二剪刀臂孔，剪刀30的第一臂位于第一剪刀臂孔内，剪刀30的第二臂位于第二剪刀臂孔内。传送杆的第二侧和传送杆的第一侧为台阶结构，传送杆的第二侧较传送杆的第一侧短。传送杆为实心杆，第一剪刀臂孔和第二剪刀臂孔分别于第一剪刀臂和第二剪刀臂相配合的斜孔，第一剪刀臂孔和第二剪刀臂孔为由传送杆的第一端穿透传送杆的侧壁的通孔。
如图2所示，在本实施例的技术方案中，传送杆的第一端的第二侧部具有与冲剪夹20相配合冲剪夹抵压板。上述结构简单，打结效果好。具体地，冲剪夹20的内壁设置有凸起结构，这样使得夹紧件100的夹持效果更好，缝合线不容易脱出。夹紧件100为夹钉。
如图1和图2所示，在本实施例的技术方案中，打结器还包括手柄和套管40，套管40的第一端与手柄相连，剪刀30和冲剪夹20位于套管40的第二端，传动杆位于套管40内。传送杆的第二端与手柄相连。上述结构操作方便，结构紧凑。套管40能够伸入身体内，这样留在身体内的缝合线较短。
在本实施例的技术方案中(图中未示出)，打结器还包括驱动部，驱动部为设置在手柄处的手动驱动部。上述结构加工成本较低。手动驱动部为扳机结构。当然，驱动部也可以为设置在手柄处的自动驱动部。这样可以实现打结器的自动驱动，降低操作人员的劳动强度。自动驱动部包括电机、液压结构等，通过操作设置在打结器上的开关按钮，电机运行即可，或者液压结构驱动，亦或者电推杆结构均是可以的。需要说明的是，完成一次打结后在手柄内弹性件或者其它动力部件的作用下传动结构10回位，从而使剪刀30由剪切状态恢复到打开状态，准备第二次打结、剪线工作。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
