带袢钛板植入装置及植入系统
交叉引用
本申请要求2021年12月27日提交的申请号为202111618056X的中国专利申请的优先权。上述申请的内容以引用方式被包含于此。
技术领域
本发明涉及医疗器械技术领域，尤其涉及一种带袢钛板植入装置及植入系统。
背景技术
带袢钛板作为骨科植入性医疗器械，是肌腱韧带固定重建的重要手段之一，其通过借助骨皮质的力量作为支撑，以悬吊的方式牢牢固定牵引受损部位，从而发挥重建作用。目前，按翻袢方式划分，带袢钛板可分为两类：依托缝线实现翻袢的带袢钛板和依托植入器械实现翻袢的带袢钛板。
依托植入器械实现翻袢的带袢钛板主要由钛板、袢环线和植入器械三部分组成。由于无需考虑牵引线的连接问题，该类产品的钛板表面只需两个供袢环线穿过的通孔即可。手术操作时，外科医生首先通过植入器械将带袢钛板送至指定位置，然后操作植入器械手柄的释放机构来完成钛板释放和翻袢动作，从而达到手术目的。
公开号为US11064993B2的美国专利公开了一种外科按钮插入器系统和方法，该专利实现翻袢动作的原理如下：在初始位置时，连接内部芯杆的弹簧处于被拉伸状态，有回撤复位趋势，但内部芯杆被限定在按钮的卡槽内，在按钮被按下前不能移动；按下手柄上方的按钮，被限位的内部芯杆得以释放，在弹簧的作用下移动；使得内部芯杆带动钛板运动，实现翻转。该专利中的外科按钮插入器的翻袢动作主要依靠内部芯杆回撤实现的。但鉴于骨端软组织复杂的 分布，存在软组织干涉钛板翻转的情况发生，该专利的结构在翻袢过程中会存在翻袢不成功，需要二次重新植入的问题。
因此，有必要提供一种新型的带袢钛板植入装置及植入系统以解决现有技术中存在的上述问题。

本发明一些实施例中，参考图2、图10至图12，所述植入系统包括所述带袢钛板植入装置100、钛板200和袢环300，所述袢环300设置于所述钛板200的穿线孔(图中未标示)，所述钛板200设置于所述带袢钛板植入装置100的所述钛板夹持部13，所述钛板200通过所述推杆2与所述翻转辅助部12配合实现翻转。
本发明一些实施例中，所述袢环300包括并不限于线圈可调型袢环。
本发明一些实施例中，所述钛板200上设有其他用于固定的植入物，如圆形纽扣钛板或编织束缚带。

本发明一些实施例中，参考图4、图13至图15，所述钛板200包括推杆容纳结构210，所述推杆容纳结构210设置于所述钛板的侧端部201，且所述推杆容纳结构210与所述推杆2的头端部21相适配。
本发明一些实施例中，参考图5、图13至图15，所述钛板200包括凹槽结构220，所述凹槽结构220设置于所述钛板200的作用端部202并与所述倒钩结构121相适配，所述作用端部202与所述侧端部201相邻设置，所述凹槽结构220设有与所述弧形凸出部122相适配的弧形凹陷部221，所述弧形凹陷部221设置于所述凹槽结构220朝向所述侧端部201的一侧。
具体的，参考图5、图13至图15，所述凹槽结构220与所述穿线孔230连通，以便于所述钛板200设置于所述钛板夹持部13的腔体内时，所述倒钩结构121能收容于所述凹槽结构220。当所述推杆2在所述推杆驱动组件(图中未标示)的驱动下推动所述钛板200朝向所述出口端14运动时，所述倒钩结构121在所述凹槽结构220中移动，且所述弧形凸出部122朝向所述弧形凹陷部221移动，直至所述弧形凸出部122抵持所述弧形凹陷部221。而后所述推杆2继续推动所述钛板200，因为所述弧形凸出部122抵持所述弧形凹陷部221，会阻挡所述钛板200继续向原始方向运动，此时所述推杆2会沿着所述推杆抵持部211向所述作用端部202移动，所述弧形凸出部122在所述弧形凹陷部221内呈弧形滑动，所述钛板200以所述弧形凸出部122在所述弧形凹陷部221的抵持位置为圆形，并绕所述倒钩结构121实现翻转。
本发明一些实施例中，参考图13至图15，所述凹槽结构220与所述侧端部 201的最小距离为第一距离L1，即靠近所述侧端部201的所述凹槽结构220的侧壁与所述侧端部201的距离为第一距离L1；所述凹槽结构220与所述侧端部201的最大距离为第二距离L2，即远离所述侧端部201的所述凹槽结构220的侧壁与所述侧端部201的距离为第二距离L2。参考图5至图15，所述倒钩结构121中的所述弧形凸出部122与所述避让槽131沿所述套管的中轴线方向的距离为L3，所述L3满足：L1<L3<L2,以便于将所述钛板200安装到所述带袢钛板植入装置100中。
本发明一些实施例中，参考图13至图15，所述推杆容纳结构210包括推杆抵持部211，所述推杆抵持部211为倾斜结构，且所述推杆容纳结构211靠近所述作用端部202的容纳空间大于所述推杆容纳结构211远离所述作用端部202的容纳空间，以使所述推杆2沿着所述推杆抵持部211向所述作用端部202移动。便于所述推杆2沿着所述推杆抵持部211移动，使得所述推杆2能一直与钛板200抵持不脱离，且有利于使所述钛板200实现翻转。
图16为本发明另一种实施例的钛板与袢环的装配剖视示意图。
本发明另一些实施例中，参考图16，所述推杆抵持部211为弧形结构，且所述推杆容纳结构211靠近所述作用端部202的容纳空间大于所述推杆容纳结构211远离所述作用端部202的容纳空间，以使所述推杆2沿着所述推杆抵持部211向所述作用端部202移动。
本发明一些实施例中，所述植入系统的操作方法包括步骤：
S1：查看所述推杆2是否回撤到所述套管11，即判断所述弹性限位件33是否与所述限位部34卡接，所述推杆驱动弹簧32是否处于锁定状态；如没有，则手动向远离所述手柄外壳4的进口端的方向拉动所述外力驱动部312，从而使所述弹性限位件33卡接于所述限位部34中，使所述推杆驱动弹簧32处于锁定状态；
S2：将带有所述袢环300的所述钛板200手动放置于所述带袢钛板植入装 置100的所述钛板夹持部13，并通过所述弹性夹持件133夹持固定所述钛板200；
S3：将组装后的所述植入系统通过预先钻好的骨髓道植入患者手术部位，可选髓腔内固定或对侧皮质骨外侧固定；透视下观察，所述钛板200完全通过骨髓道即为钛板释放位置，如图11所示；
S4：按压所述施力件35，使所述贯穿部351朝向所述收容结构314运动，所述贯穿部351贯穿压迫所述贯穿孔结构333，使所述凸起部332向远离所述限位部34的方向运动，从而使所述弹性限位件33从所述限位部34中脱离；所述弹性限位件33从所述限位部34中脱离后，在所述推杆驱动弹簧32的弹力下驱动所述推杆连接件31，从而使所述推杆连接件31带动所述推杆2朝向所述出口端14运动；所述推杆2朝向所述出口端14的运动过程中，会接触并插入所述推杆容纳结构210中，从而推动所述钛板200朝向所述出口端14运动；所述钛板200朝向所述出口端14移动一段距离后，所述弧形凹陷部221与所述弧形凸出部122接触，此时所述钛板200被所述倒钩结构121阻挡，不再向前移动。在所述推杆2的继续推动下，处于偏心位置的所述钛板200绕所述弧形凸出部122的圆心转动，从而使所述钛板200实现了翻转，如图12所示；
S5：透视下观察所述钛板200翻转情况，如钛板200完成翻转，将所述带袢钛板植入装置100从骨髓道抽离，然后根据具体手术情况完成缝线的固定；如所述钛板200未能完全翻转，按压所述外力驱动部312，通过手动驱动所述推杆连接件31，从而带动所述推杆2朝向所述出口端14运动，以实现手动协助完成所述钛板200的翻转，使得在以所述推杆驱动弹簧32为推力不足以完成所述钛板200翻转时，对所述外力驱动部312采用手动施加推力即可协助完成所述钛板200的翻转动作，无需二次重新植入。所述钛板200翻转完成后，所述推杆2始终抵持于所述钛板200，直到人为将所述带袢钛板植入装置100从骨髓道撤回时，所述推杆2随所述带袢钛板植入装置100一同撤回，而所述钛板200因骨髓道的阻挡留置在骨髓道内。当所述带袢钛板植入装置100从骨隧道撤出时，只要所述钛板200已经翻转，不再处于水平位置，所述钛板200就会因为 骨隧道的阻挡而不能随所述带袢钛板植入装置100脱出，就已完成所述钛板200的植入。
其中，钛板200的翻转可小于90度，因为钛板翻转后，可通过收紧所述袢环300的缝线而会把所述钛板200拉向骨面。
虽然在上文中详细说明了本发明的实施方式，但是对于本领域的技术人员来说显而易见的是，能够对这些实施方式进行各种修改和变化。但是，应理解，这种修改和变化都属于权利要求书中所述的本发明的范围和精神之内。而且，在此说明的本发明可有其它的实施方式，并且可通过多种方式实施或实现。
