Translated fromChinese技术领域technical field
本实用新型涉及医疗器械技术领域，特别涉及一种肌腱编织装置。The utility model relates to the technical field of medical instruments, in particular to a tendon weaving device.
背景技术Background technique
骨科及运动医学的损伤性疾病中交叉韧带损伤是较常见的疾病之一，前交叉韧带损伤是膝关节肌腱损伤中发病率是最高的。在交叉韧带手术中，肌腱编织是很重要的一个步骤，编织后的肌腱的质量对交叉韧带重建手术成功与否会产生重要影响。肌腱编织失败会直接导致交叉韧带重建手术失败。Cruciate ligament injury is one of the more common diseases in orthopedics and sports medicine. Anterior cruciate ligament injury is the highest incidence of knee tendon injury. In cruciate ligament surgery, tendon weaving is an important step, and the quality of the woven tendon will have an important impact on the success of cruciate ligament reconstruction surgery. Failure of tendon braiding can directly lead to failure of cruciate ligament reconstruction surgery.
目前临床上常用的肌腱编织方法为：使用肌腱固定夹，夹持肌腱，用带有2号不可吸收聚乙烯缝线的圆针将肌腱两端编织缝合，缝合线跨肌腱中线，有一定交叉。但是在编织过程中，一方面无法控制针距，如果针距过小，编织线紧密包裹肌腱，在肌腱与骨隧道之间形成空隙，会影响腱骨愈合。若针距过大，则会造成编织段过长，在关节腔内会有编织线外露，可能会引起滑膜反应。另一方面，目前在肌腱编织中常用的带线缝针为半弧形圆针，因半弧形缝针需要两把持针钳配合完成肌腱编织操作，操作困难且时间长，目前常用的编织方法需要进行两侧的编织，因此较长时间才能完成肌腱编织，延长了手术时间，影响手术的进行。而半弧形圆针的针尖对肌腱组织损伤较大，容易造成对肌腱的线性切割，从而造成肌腱撕裂。At present, the commonly used tendon knitting method in clinical practice is as follows: use a tendon fixation clip to clamp the tendon, and use a round needle with No. 2 non-absorbable polyethylene suture to weave and suture both ends of the tendon. However, during the knitting process, on the one hand, the needle pitch cannot be controlled. If the needle pitch is too small, the braided thread tightly wraps the tendon, forming a gap between the tendon and the bone tunnel, which will affect the healing of the tendon and bone. If the needle distance is too large, the braided segment will be too long, and the braided thread will be exposed in the joint cavity, which may cause synovial reaction. On the other hand, the commonly used stitching needles in tendon knitting are semi-arc circular needles. Because the semi-arc stitching needle requires two holding needle forceps to complete the tendon knitting operation, the operation is difficult and time-consuming. The currently commonly used knitting method Both sides need to be braided, so it takes a long time to complete the tendon braiding, which prolongs the operation time and affects the operation. On the other hand, the needle tip of the semi-arc-shaped round needle causes great damage to the tendon tissue, which is likely to cause linear cutting of the tendon, resulting in tendon tearing.

优选的，在将所述第一组合件1与所述第二组合件2分别绕过肌腱组织4后再次装配的步骤中，所述第一组合件1与所述第二组合件2分别绕过肌腱组织4半周，以使重复执行所述组合体自肌腱组织4中穿过的步骤时，所述组合体7的穿入点(第一预定针孔41、第二预定针孔42以及后续的若干针孔)位于肌腱组织4的同一周向位置上。即多个穿入点排列成平行于肌腱组织之轴向的一直线。Preferably, in the step of reassembling after passing the
如此配置，在将第一组合件1和第二组合件2组合装配后，可一次穿过待编织的肌腱组织4，并拉紧缝线3。而后可将第一组合件1和第二组合件2分离，令其环绕待编织的肌腱组织4后，可再次将第一组合件1和第二组合件2组合装配，以重复执行穿过-拉紧-分离的步骤，来完成对待编织的肌腱组织4的编织过程。由于第一组合件1和第二组合件2组合装配后，一次穿过待编织的肌腱组织4，仅有一个穿刺点，即可完成肌腱两侧的缝合，一方面节省了手术时间，提高了肌腱编织的效率；另一方面减少了对肌腱组织4的损伤，有利于患者术后的康复。In this configuration, after the combined assembly of the
请参考图3，在一个可替代的示范例中，所述第一组合件1具有内腔10，所述内腔10朝所述第一组合件1的尾端1b开放，所述第二组合件2用于自所述内腔10开放的一端穿入，以与所述第一组合件1装配。第一组合件1和第二组合件2内外装配的方式，一方面便于操作，另一方面也有利于减小第一组合件1和第二组合件2的组合体穿过肌腱组织4的阻力，有利于减小对肌腱组织4的性切割，避免肌腱断裂。Referring to FIG. 3 , in an alternative example, the
可选的，第一组合件1的头端1a为尖锐形。需要说明的，这里的尖锐形，如可为锥形或棱锥，其尖端的角度优选小于30°，以便于对肌腱组织4进行穿刺。优选的，第一组合件1的外轮廓的横截面为圆形，其大致为一圆柱状的针状件。优选的，所述第二组合件2的头端为钝形，钝形如可为钝圆形等形状，也可以如圆台等形状，其相对于尖锐形，不易刺破操作者的手。Optionally, the head end 1a of the
进一步的，所述第二组合件2的外轮廓与所述内腔10相适配，所述第二组合件2在穿入所述内腔10后，被所述内腔10限制沿径向的移动。在一个示范例中，所述内腔10的横截面为圆形，所述第二组合件2的横截面为圆形，第二组合件2的外径与内腔10的内径相适配，即第二组合件2的外径略小于内腔10的内径，第二组合件2能够较为紧密地配合，但应保证第二组合件2的插入拔出无卡涩感，其能够顺滑地插入内腔10或从内腔10中拔出。当然本实用新型对第二组合件2的外轮廓以及内腔10的形状不作特别的限制，其并非限制必须为圆形。例如在其它的一些实施例中，第二组合件2的外轮廓和/或内腔10的形状为多边形，只要两者能够相互配合即可。Further, the outer contour of the
可选的，所述肌腱编织装置还包括导向轨5，所述导向轨5与所述第一组合件1的尾端1b连接，并沿所述第一组合件1的轴向延伸，所述导向轨5用于引导所述第二组合件2穿入所述内腔10的方向。导向轨5的设置，用于在第二组合件2穿入内腔10时对第二组合件2进行引导。具体的，第二组合件2在穿入内腔10前，可先抵靠于第二组合件2上，然后顺着导向轨5滑入内腔10中。优选的，所述导向轨5的横截面为与所述第二组合件2的横截面相适配的弧形。弧形的导向轨5能够顺滑地对第二组合件2进行引导。Optionally, the tendon braiding device further includes a
可选的，所述缝线3通过所述导向轨5与所述第一组合件1的尾端连接；或者，所述缝线3直接与所述第一组合件1的尾端连接。需要说明的，第一组合件1的尾端通过缝线3与第二组合件2的尾端连接，并非限定所述缝线3与所述第一组合件1的尾端必须是直接连接的，两者也可以是间接连接的，例如缝线3与第一组合件1两者可通过导向轨5间接地连接。当然另一些实施例中，缝线3也可以与第一组合件1的尾端直接连接，此时导向轨5仅起到引导作用。Optionally, the
可选的，所述第一组合件1的外表面和/或所述第二组合件2的外表面具有沿轴向分布的刻度6。刻度6如可按2mm的间距分布。使用时，在编织过程S2中，缝线3缠绕于肌腱组织4上，并分离第一组合件1与第二组合件2后，可将第一组合件1或第二组合件2横过来作为标尺来使用，比划着确定下一个穿刺点的大致位置。进而再将第一组合件1或第二组合件2组合装配，继续穿刺和编织的过程。优选的，在执行所述重复编织过程S3时，沿肌腱组织4的轴向依次移动预定间隔；所述预定间隔以所述第一组合件1和/或所述第二组合件2的刻度6为参考，例如相邻两个穿刺点(例如第一预定针孔41和第二预定针孔42)的间距可为2mm。Optionally, the outer surface of the
请参考图4，可选的，所述第一组合件1的尾端1b具有第一定位部11，所述第二组合件2的尾端2b具有第二定位部21，所述第一定位部11用于与所述第二定位部21相配合，以限制所述第一组合件1相对于所述第二组合件2的周向位置。在一些实施例中，第一组合件1的内腔10和第二组合件2的形状都是圆形的，则两者能够产生相对的周向转动，这容易使缝线3产生扭曲。而第一定位部11与第二定位部21相配合后，可以限制第一组合件1相对于第二组合件2的周向位置，从而限制两者产生相对的周向转动。Please refer to FIG. 4 , optionally, the
在一个可替代的示范例中，所述第一定位部11包括沿所述第一组合件1的轴向开设的第一凹凸结构，第一凹凸结构可设置在第一组合件1的尾端面上；所述第二定位部包括沿所述第二组合件2的轴向设置的第二凹凸结构，第二组合件2的尾端如可包括一个外径与第一组合件1的外径相匹配的堵台，该堵台具有朝向第二组合件2的头端2a方向的结合面，第二凹凸结构可设置在该结合面上。所述第二凹凸结构用于与所述第一凹凸结构相适配卡合。第一凹凸结构和第二凹凸结构如可为相适配的齿轮，或其它的形状，本实用新型对此不限。In an alternative example, the
在另一个可替代的示范例中(未图示)，所述第一组合件1的内腔表面具有第一定位部11，所述第二组合件2的外表面具有第二定位部21，所述第一定位部11用于与所述第二定位部21相配合，以限制所述第一组合件1相对于所述第二组合件2的周向位置。可选的，所述第一定位部11包括沿所述内腔10的周向开设的第一凹凸结构，所述第二定位部2包括沿所述第二组合件2的外表面的周向设置的第二凹凸结构，所述第一凹凸结构与第二凹凸结构相互适配卡合。In another alternative example (not shown), the inner cavity surface of the
