Description

一种微创手术器械及其打结的方法 技术领域
本发明涉及一种微创手术器械及打结方法，属于医疗器械技术领域。
背景技术
微创手术时，手术缝合结束时，需要在缝合处对缝合线进行打结，然后将多余的缝合线剪断。由于微创手术是通过体表切口将手术器械伸入体内进行手术，手术刀口太小、无法直视到需要打结的部位，受限于手术空间，打结的操作动作通常需分别采用多种手术器械相互配合才能完成，而且由于缝合线圈易从手术器械端部滑脱，缝合线张紧力不容易控制等因素，导致缝合线打结一次成功率低，手术时间长，缝合打结效果差。
另一方面手术过程中使用的手术器械繁多，操作复杂，频繁更换手机器械，不利于提高手术效率。
发明内容
发明目的：本发明所要解决的技术问题是克服现有技术的缺陷，提供一种微创手术器械及其打结的方法，可以方便快捷的完成打结操作。
技术方案：为解决上述技术问题，本发明提供一种微创手术器械，其特征是，由第一钳柄和第二钳柄交叉于一连接点形成首端为夹头、末端为控制夹头张开或闭合的手柄；
第二钳柄的首端端部具有一套线部；第一钳柄和第二钳柄闭合时，套线部与第一钳柄首端相抵靠在一起，形成一封闭的内部空间；第一钳柄和第二钳柄张开时，套线部与第一钳柄首端分开形成张开的端口；
第一钳柄的首端内侧连接一拨片，拨片与第一钳柄之间形成一可容纳缝合线的夹缝；拨片的固定端连接在第一钳柄上，拨片的自由端靠于套线部上，并且不受套线部的限制随第一钳柄的运动而运动。
在第一钳柄、第二钳柄上设置一固定件，所述固定件上设置限定缝合线走向的钩线部。
所述固定件为片状或筒状。
所述固定件为一套设在第一钳柄、第二钳柄上的套筒，套筒上具有一凹槽，凹槽中设置一可将缝合线钩于凹槽中的钩线部。
沿套筒轴向设置一与凹槽连通的线槽，使缝合线沿线槽进入凹槽中，并钩于凹槽中的钩线部上。
所述固定件上设置多个位置相互错开的钩线部。
所述套线部上套设一可转动的滚柱。缝合线在送线时，滚柱可以滚动，易于送线。
拨片与第一钳柄之间形成的夹缝由端口向内逐渐缩小。
在手柄一侧的第一钳柄和第二钳柄上还设置有可配合啮合的卡齿，由卡齿增加第一钳柄和第二钳柄的张开阻力。
所述套线部为朝向第一钳柄的首端端部具有一开口的半封闭拓扑结构，如半封闭环等。
一种微创手术器械打结的方法，其特征是，包括以下步骤：
(1)上线：将在体内手术缝合后剩余的缝合线在体外打一个松驰的结，形成一松驰的缝合线圈；通过手柄打开第一钳柄和第二钳柄，使夹头张开，将该缝合线圈套于套线部上，并且位于拨片与第一钳柄形成的夹缝之间，闭合第一钳柄和第二钳柄；
将从缝合线圈向外延伸的缝合线拉入钩线部，由钩线部限定缝合线的走向，使缝合线理顺，缝合线置于体外的外部端手持；
(2)送线：沿着从体内延伸出的缝合线向体内推送缝合线圈，随着套线部的推送，缝合线圈逐渐沿缝合线向体内移动，直至被推送至体内缝合处适宜打结的位置；
(3)打结：打开第一钳柄和第二钳柄，使夹头张开，拨片随第一钳柄向外运动，将套设在套线部上的缝合线圈向外拨出脱离套线部，并从张开的夹头上脱离；
拉紧缝合线，使从套线部上脱离的缝合线圈被拉紧形成最终的结。
有益效果：
本发明的微创手术器械，改变目前采用的体内打结方式，在体外手动打结后，由本发明的手术器械将结输送至体内缝合处，并使结打紧，然后，由切齿将缝合线剪断。采用本发明的手术器械，避免了缝合线圈从手术器械端部滑脱，打结成功率非常高，几乎可以达到100％，可以方便快捷的完成打结操作，集打结、剪断缝合线功能为一体，减少了手术中器械的使用数量，利于提高手术效率。

具体实施方式
下面结合附图对本发明作进一步描述。以下实施例仅用于更加清楚地说明本发明的技术方案，而不能以此来限制本发明的保护范围。
实施例1
如图1、图2、图3和图4所示，本发明的微创手术器械与一般的手术钳形状大致相同，呈剪刀形状，由两根钳柄1交叉于一连接点形成了首端为夹头2、末端为手指控制操作的手柄3，夹头2由手柄3控制张开或闭合，夹头2闭合后形成一可容纳缝合线的内部空间。
两根钳柄分别为第一钳柄11和第二钳柄12。其中，第二钳柄的首端121端部具有一套线部4，套线部4上套设一滚柱41(在图5中示出)，当缝合线圈套于夹头2中套线部4上向体内输送时，滚柱41可随缝合线圈的运动而滚动，减小送线阻力，利于顺畅地送线。第一钳柄11和第二钳柄12闭合时，套线部4与第一钳柄首端111相抵靠在一起，阻挡套于套线部4上的缝合线圈脱离；第一钳柄11和第二钳柄12张开时，套线部4与第一钳柄首端111相离开，使夹头2内的缝合线圈可从端口6脱出。
为了防止第一钳柄11和第二钳柄12张开时，夹头2内的缝合线圈依然套在套线部4上，不易从夹头2内脱出，在夹头2内部空间中第一钳柄11的首端111内侧连接一拨片5，拨片5由端口向夹头2内部空间延伸，延伸方向与第一钳柄11同向，拨片5位于夹头2内部的固定端连接在第一钳柄11上，另一端为贴近夹头2端口套线部4的自由端51。拨片5与第一钳柄11之间形成一可容纳缝合线的夹缝7，夹缝7由端口6向内逐渐缩小。拨片5随第一钳柄11的运动而运动，当操作手柄3控制第一钳柄11、第二钳柄12张开时，拨片5随第一钳柄11向外运动，可将套设在套线部4上的缝合线圈向外拨出，使缝合线圈脱离第二钳柄12的套线部4，并从张开的夹头2上脱离。拨片5自由端51与第一钳柄11之间的夹缝距离以夹头2张开至最大开口时，即拨片5自由端51向外移动最大距离时，拨片5自由端仍贴于套线部4而不与套线部4分离为宜，以防止在送线开始前，第一钳柄11、第二钳柄12处于张开状态，将缝合线圈套于套线部4上时，缝合线圈被夹持在拨片5与第二钳柄12间，而非拨片5与第一钳柄11形成的夹缝7之间。
在第一钳柄、第二钳柄上设置一固定件8，用于固定限定缝合线走向的钩线部。如图1、图3所示，固定件8可以为柱形的套筒8A，套筒8A套设在第一钳柄11、第二钳柄12上的连接点处，用以覆盖连接点，一方面可防止缝合线被夹于连接点中，同时，由套筒限制夹头2可以张开的最大张开度。根据杠杆原理，通常连接点设置的更靠近夹头2方向，便于操作末端的手柄3，操作夹头2进行较小幅度的启闭。为了较小的限制手柄3的张开度，不阻挡手柄3的张开，可以在套筒8A靠近手柄3的一端设置避让槽8A1，以避让手柄3张开时的第一钳柄11和第二钳柄12。
套筒8A上具有一凹槽8A2，凹槽8A2中设置一挡钩9A，可将缝合线绕于凹槽8A2中，并由挡钩9A钩住不脱离套筒。凹槽8A2与套线部4之间的套筒8A上沿套筒8A轴向设置一线槽10，即线槽由夹头2向手柄3方向延伸。线槽10与凹槽8A2连通，使缝合线沿线槽10进入凹槽8A2中。
手柄3结构为分别设置在第一钳柄11和第二钳柄12末端的一套环31，每个套环31可容纳一根手指伸入其中进行控制操作。
在套环31与套筒8A之间的第一钳柄11和第二钳柄12上还设置有可配合啮合的卡齿131、132，卡齿131、132用于防止闭合的第一钳柄11和第二钳柄12误打开，若要打开闭合的第一钳柄11和第二钳柄12，需克服卡齿的阻力，以避免第一钳柄11和第二钳柄12在送线过程中误打开后，套于套线部4上的缝合线圈从夹头2中脱落。
如图2、图4所示，固定件8也可以为一固定片8B，固定片8B上设置两个位置相互错开的挂线钩9B。
使用本发明的微创手术器械对微创手术缝合后的缝合线进行打结的操作过程为：
1、上线：将在体内手术缝合后剩余的缝合线在体外打一个松驰的结，形成一缝合线圈，暂不将该缝合线圈拉紧(只在拉紧后才会形成最终的结)；通过手柄3打开第一钳柄11和第二钳柄12，使夹头2张开，如图3的张开状态，将该缝合线圈套于套线部4上，并且位于拨片5与第一钳柄11形成的夹缝之间，通过手柄3闭合第一钳柄11和第二钳柄12，使夹头2闭合，如图4的闭合状态，并由卡齿卡紧保证闭合不会被误操作而打开。
将从缝合线圈向外延伸的缝合线嵌入线槽10，并由挡钩钩于凹槽8A2中，缝合线置于体外的外部端由手持该手术器械的医生把持。
2、送线：沿着从体内延伸出的缝合线向体内推送手术器械，随着套线部4的推送，缝合线圈逐渐沿缝合线向体内移动，直至被推送至体内缝合处适宜打结的位置。
3、打结：拉紧缝合线位于体外的外部端，使缝合线圈由松驰状态变为略紧的小线圈；
通过手柄3控制打开第一钳柄11和第二钳柄12，使夹头2张开，拨片5随第一钳柄11向外运动，将套设在套线部4上的缝合线圈向外拨出，使略紧的小线圈脱离套线部4，并从张开的夹头2上脱离。
此时，可再次拉紧缝合线，使从套线部4上脱离的小线圈被拉紧形成最终的结。
实施例2
为了防止在使用该手术器械向体内送线过程中，套在套线部4上的缝合线圈从套线部4滑向侧面的第一钳柄11或第二钳柄12上，较佳地，根据拓扑结构设计套线部4，如图5所示，第一钳柄11、第二钳柄12的首端端部侧面分别连接一滑杆112、122，并且两根滑杆的末端可相对运动地搭接在一起，第一钳柄11、第二钳柄12运动时，两根滑杆之间的搭接处仍不会分离，防止缝合线圈从套线部4上滑到第一钳柄11或第二钳柄12上。
其余与实施例1相同。
实施例3
为了防止在使用该手术器械向体内送线过程中，套在套线部4上的缝合线圈从套线部4滑向侧面的第一钳柄11或第二钳柄12上，较佳地，根据拓扑结构设计套线部，如图6所示，将套线部4设计成仅朝向第一钳柄11的首端端部具有一开口421的半封闭环42，使套线部4与两侧的第一钳柄11或第二钳柄12形成隔离，防止缝合线圈滑向第一钳柄11或第二钳柄12。
其余与实施例1相同。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和变形，这些改进和变形也应视为本发明的保护范围。

  5. 根据权利要求4所述的微创手术器械，其特征是，沿套筒轴向设置一与凹槽连通的线槽，使缝合线沿线槽进入凹槽中，并钩于凹槽中的钩线部上。
  6. 根据权利要求2或3所述的微创手术器械，其特征是，所述固定件上设置多个位置相互错开的钩线部。
  7. 根据权利要求1所述的微创手术器械，其特征是，所述套线部为朝向第一钳柄的首端端部具有一开口的半封闭拓扑结构。
  8. 根据权利要求1或7所述的微创手术器械，其特征是，所述套线部上套设一可转动的滚柱。
  9. 根据权利要求1所述的微创手术器械，其特征是，拨片与第一钳柄之间形成的夹缝由端口向内逐渐缩小。
  10. 根据权利要求1所述的微创手术器械，其特征是，在手柄一侧的第一钳柄和第二钳柄上还设置有可配合啮合的卡齿。
  11. 基于权利要求1所述的微创手术器械的打结的方法，其特征是，包括以下步骤：
    (1)上线：将在体内手术缝合后剩余的缝合线在体外打一个松驰的结，形成一松驰的缝合线圈；通过手柄打开第一钳柄和第二钳柄，使夹头张开，将该缝合线圈套于套线部上，并且位于拨片与第一钳柄形成的夹缝之间，闭合第一钳柄和第二钳柄；
    将从缝合线圈向外延伸的缝合线拉入钩线部，由钩线部限定缝合线的走向，使缝合线理顺，缝合线置于体外的外部端手持；
    (2)送线：沿着从体内延伸出的缝合线向体内推送缝合线圈，随着套线部的推送，缝合线圈逐渐沿缝合线向体内移动，直至被推送至体内缝合处适宜打结的位置；
    (3)打结：打开第一钳柄和第二钳柄，使夹头张开，拨片随第一钳柄向外运动，将套设在套线部上的缝合线圈向外拨出脱离套线部，并从张开的夹头上脱离；
    拉紧缝合线，使从套线部上脱离的缝合线圈被拉紧形成最终的结。
