背景技术
在操作内窥镜的手术过程中，可能因病灶的大小问题，容易导致内镜前端被覆盖，影响术者视野，因此，针对上述存在的问题，现有技术中主要是通过能够对手术部位附件的组织进行固定牵拉的医用牵拉器来避免手术部位附近的组织阻挡手术视野。
例如公开号为CN208725782U公布的医用牵拉器及医疗器械，通过按压两个弹力夹持臂可以使得两个弹力夹持臂的端部相互远离，即能使得夹持空间张开，如此，便能将手术部位周围组织放入至夹持空间内部；而松开两个弹力夹持臂时，则能通过弹力夹持臂的弹性回复力使得夹持空间封闭，也就能稳定地对手术部位周围组织进行夹持。需要说明的是，对于同一个需要进行手术的病灶来说，当病灶旁边的组织面积对于病灶的遮挡影响较大时，可能使用一个牵拉器对组织进行固定牵拉还不足以解决组织对于手术部位遮挡的问题，这样的情况下，可能需要两个甚至更多个牵拉器来对组织进行牵拉，此时，如果采用上述公开号公开的医用牵拉器，就需要单独采用多个彼此独立的牵拉器进行操作，这样的结构会造成整体的使用繁琐，而且存在牵拉器的牵引线互相干扰的问题，操作不便。

具体实施方式
现在结合附图对本公开作进一步详细的说明。这些附图均为简化的示意图，仅以示意方式说明本公开的基本结构，因此其仅显示与本公开有关的构成。
实施例1：
如图1至图5所示，本实施例提供了一种组织拉钩100，包括：固定套管101和适于部分地收拢在固定套管101内的夹片部102。详细来说，固定套管101包括具有中空容纳腔2的管状体结构的本体1，以及与本体1的的轴向端一体成型的弧形结构的凸翅103。夹片部102包括适于相对于凸翅103张开和闭合的活动片104，以及与活动片104一体相连的且适于收拢至中空容纳腔2内的连接片6，此处需要说明的是，对于本实施例的连接片6采用具有一定变形弹性的材质制成，此外，对于本实施例涉及的组织拉钩100，可以是金属材质制成，也可以是可降解材料制成，对此，本实施例不做绝对限定。
再具体的，凸翅103包括从本体1的径向边缘沿着本体1的纵长轴线方向延伸的基部3，以及基部3上相对远离本体1的端部一体弯折成型的翅尖部4；翅尖部4由基部3向本体1的中轴线方向弯折。活动片104包括适于沿着平行于本体1的轴线方向延伸的基片7，以及与基片7一体弯折成型的且适于与翅尖部4配合的翅翼部8。在活动片104相对于凸翅103为闭合状态时，翅翼部8适于与翅尖部4相对以夹紧组织。也就是说随着连接片6不断向本体1的中空容纳腔2中回缩时，活动片104逐渐向凸翅103方向活动以缩小活动片104与凸翅103之间存在的空间。
参见图7-图8，夹片部102还包括平板部105，连接片6的一端连接活动片104，连接片6的另一端连接平板部105。在活动片104相对于凸翅103为张开状态时，连接片6与止挡轴30间隔预设距离，此时平板部105是悬置在中空容纳腔2之中的，而在活动片104相对于凸翅103为闭合状态时，则连接片6与止挡轴30接触，并且活动片104与凸翅103接触，平板部105的一端与中空容纳腔2的内壁抵接。
考虑到为了提高活动片104与凸翅103对组织的夹紧效果，本实施例还在翅翼部8适于朝向翅尖部4的端部开设有抓取部19。此处的抓取部19可以形成对于一部分人体组织的容置空间，这样通过一部分的组织进入抓取部19的容置空间内以降低组织从本实施例提供的组织拉钩100内滑脱的概率。本实施例当中，抓取部19呈V形或者W形槽。
还可选的情况下，在组织拉钩100对于人体组织进行夹紧固定后为了便于对人体组织进行牵拉的时候，提高牵拉的效率，在基部3朝向活动片104的侧端设有至少一凸起的适于***人体组织内的***部10；***部10相对于基部3弯折成型，且***部10向本体1的纵长中心轴线所在方向歪斜，通过***部10可以实现组织拉钩100与人体 组织的深度配合。
此外，对于本实施例的连接片6来说，以一种可选的实施情况为例，连接片6为Z形结构，且Z形结构的折角处呈圆弧过渡；以及活动片104与连接片6的连接处呈圆弧过渡，以使得活动片104与连接片6共同构建形成S形状体，这样的结构下，使得在连接片6由本体1外逐渐回缩至本体1的中空容纳腔2时，S形结构可以通过变形来实现与连接片6相连的活动片104，进行朝向凸翅103方向的运动，从而使得凸翅103与活动片104之间由张开的状态逐渐形成闭合的状态。
对于本实施例的组织拉钩100来说，当凸翅103与活动片104之间呈张开状态时，连接片6部分地随着活动片104位于中空容纳腔2外，随着连接片6逐渐向中空容纳腔2中回缩时，活动片104逐渐向凸翅103一侧活动以缩小活动片104与凸翅103之间的距离，从而最终实现凸翅103与活动片104对于人体的组织的夹持。
实施例2：
请参阅图6至图12所示，在实施例1的组织拉钩100的基础上，本实施例提供了一种医用牵拉器，包括实施例1的组织拉钩100、与组织拉钩100的本体1背离凸翅103的端部一体成型的适于形变的收窄口11、与收窄口11可分离式配接的过渡管5，以及穿过过渡管5后适于对组织拉钩100的连接片6进行牵拉的推拉机构。
详细来说，结合图3以及图6、图7，推拉机构包括与连接片6远离活动片104的一端固连的连接件12、适于在本体1的中空容纳腔2中沿着本体1的轴线移动的且与连接件12卡接的缺口拉杆13、以及与缺口拉杆13相连的适于推拉该缺口拉杆13的推拉组件。
其中，缺口拉杆13上设有一开口通孔15，且该缺口拉杆13的侧边沿设有与开口通孔15连通的豁口16，开口通孔15的中心轴线与缺口拉杆13的纵长轴线相互垂直；连接件12适于通过豁口16实现与开口通孔15的配接和分离。此处的连接件12采用例如但不限于铆钉结构。
此外，推拉组件包括与缺口拉杆13远离开口通孔15的一端固连的拉管17、与拉管17背离缺口拉杆13的一端套接固定的拉索18，以及在拉管17的外侧壁上设有的适于与收窄口11的内腔壁抵接的撑开部21；其中收窄口11沿着平行于本体1的轴线方向开设有至少一条缺槽；过渡管5与撑开部21套设，具体而言，一部分撑开部21可滑动的收容在过渡管5当中，而另一部分撑开部21则收容在本体1当中，且收窄口11适于在撑开部21的作用下变形以实现收窄口11与撑开部21的脱离。也就是说，通过缺槽的结构，使得收窄口11的内径在形变之下可以发生变化，这样的话，通过收窄口11 的形变可以实现相对于撑开部21的脱离，也就是本体1相对于过渡管5的分离。
还需要特别说明的是，在撑开部21的外侧壁上设有环形结构的环形凹槽20，此处的环形凹槽20用于形成与收窄口11的配合，并且此处的配合针对的是活动片104相对于凸翅103处于张开状态的情况下，而随着活动片104与凸翅103逐渐闭合的过程，撑开部21在拉索18的作用下逐渐随着拉管17向远离固定套管101的方向移动时，收窄口11也会与环形凹槽20分离，使得撑开部21上的其它外侧壁部分形成对于收窄口11的撑开效果而使得收窄口11形变。
再者来说，过渡管5远离固定套管101的端部通过连接管27与弹簧管28相连；弹簧管28远离过渡管5的一端连接有芯杆23，芯杆23上滑套设有一滑环25；拉索18的尾端与滑环25固连，以适于由滑环25拉动拉索18。也就是说通过拉动滑环25，使得滑环25沿着芯杆23向远离弹簧管28的一端移动时，滑环25带动拉索18，再由拉索18产生对于缺口拉杆13向远离固定套管101的方向移动，在此移动过程中，撑开部21逐渐向远离固定套管101的方向移动，当撑开部21移动至收窄口11时，在撑开部21的作用下，收窄口11形变使得收窄口11的内径变大，如此，即可使得收窄口11与撑开部21之间形成分离的效果。
在组织拉钩100与缺口拉杆13和过渡管5的分离后，也就是说缺口拉杆13与连接片6之间脱离，缺口拉杆13对于连接片6的拉动作用也就相应消失了，为了便于在这样的情况下还能保持活动片104与凸翅103之间对于人体组织的夹持状态，不会因为缺口拉杆13的作用消失而出现活动片104与凸翅103之间状态的变化，本实施例的医用牵拉器包括在中空容纳腔2内靠近基部3的端口沿着本体1的径向设有止挡轴30，止挡轴30与本体1的侧壁固连以保持止挡轴30相对于中空容纳腔2的位置的稳定性；在连接片6收拢至中空容纳腔2内后，连接片6背离缺口拉杆13的侧端面适于与止挡轴30抵接。连接片6与凸翅103被止挡轴30分隔在本体1的两侧。在夹取紧固组织的过程当中，止挡轴30充当一个支点，在中空容纳腔2当中，通过将连接片6与平板部105稳定，从而将一体连接的活动片104相对稳固。
具体来说，由于活动片104与连接片6共同构建形成S形状体，在连接片6逐渐收拢至中空容纳腔2的过程中，连接片6会产生一定的挤压变形以使得连接片6位于中空容纳腔2外的部分易于收拢进中空容纳腔2内，而在连接片6完全地进入中空容纳腔2中后，活动片104与连接片6连接处的圆弧过渡会抵接在中空容纳腔2的近本体1的端口处，而连接片6会适当恢复其形状，这样，L形结构的连接片6上靠近活动片104的部分恰好从中空容纳腔2内的一侧抵接在止挡轴30上，综上，结合止挡轴30对于L 形结构的连接片6上靠近活动片104的部分的止挡和活动片104与连接片6连接处的圆弧过渡与中空容纳腔2的近本体1的端口处的抵接共同来保持活动片104与凸翅103之间夹持人体组织的状态的稳定性，不会因为缺口拉杆13对连接片6的作用消失而改变。
本实施例的医用牵拉器具体的实施原理如下：
通过向远离固定套管101的方向拉动滑环25，从而带动拉索18和拉管17的轴向移动，具体来说，拉索18与拉管17之间为焊接，而拉管17与缺口拉杆13之间为焊接固定，因此拉管17的轴向移动使得缺口拉杆13同步实现相对于固定套管101的本体1的轴向移动。即在拉动滑环25的过程中，实现活动片104相对于凸翅103由张开状态向封闭状态的过渡，使得凸翅103和活动片104可以对准人体的需要夹紧固定的组织部分进行夹紧固定。待完成对于人体组织的夹持后，继续拉动滑环25，套设在缺口拉杆13外侧的锁紧夹片24，锁紧夹片24在缺口拉杆13被拉动之后，缺口拉杆13设置开口通孔15的一端与锁紧夹片24抵接带动锁紧夹片24轴向滑动，继续拉动，则由锁紧夹片24抵接在撑开部21位于本体1当中的一端，此时，锁紧夹片24与撑开部21形成面接触，因此可以提高拉动的稳定性，在不断施加轴向拉力的过程中，缺口拉杆13的豁口16处变形，使得缺口拉杆13与连接件12之间脱离；再继续拉动滑环25，撑开部21撑开固定套管101的收窄口11部分，使得收窄口11的内径变大，进行实现撑开部21与固定套管101的本体1之间的脱离，综上，即可实现组织拉钩100与缺口拉杆13和过渡管5的分离。
