Description

技术领域
本发明属于医疗器械领域， 更具体的说， 涉及一种颞下颌关节盘缝合 复位固定器械。
自上世纪九十年代， 国际上曾有学者尝试用微创手术 （内镜） 治疗颞 下颌关节 （temporomandibular joint,TMJ) 盘移位。 所有方法的共同特点是 均采用关节盘后区的牵引缝合， 来试图将关节盘恢复至正常位置， 但术后 的影像学检查显示： 多数关节盘未被复位。 自 90年以来， 本发明人相继效 仿美国（McCain, 1992 )和日本 (Ohnishi, 1991)具有代表性的方法， 但 90%以 上的 TMJ关节盘无法恢复至正常的位置。这促使我们重新审视该手术本身 的科学性， 找出其在设计上存在的缺陷， 主要表现在： ①缝合牵引的方向 与移位的关节盘前后向长轴不完全一致； ②均用单线缝合， 而且单线缝合 位于关节盘的外 1/3， 故无法使内外径长达 2cm的关节盘稳定在正常位置。 为了克服上述缺陷， 本发明人研制出适用于新的关节镜下关节盘复位固定 术中的缝合器械。
在颞下颌关节盘复位固定手术中， 由于没有合适的手术器械， 使该类 手术一直没有很好的进展， 临床中一般采用结石钳拉出缝合线， 该方法不 容易将缝合线与缝合针完全锁定， 手术时易将缝合线滑脱， 致使手术重复 同一动作， 给患者增加痛苦， 缝合针没有手柄， 不容易操作。
发明内容
本发明的目的是提供一种适用于新的关节镜下颞下颌关节盘复位固 定手术、 便于操作、 手术时缝线不易滑脱的颞下颌关节盘缝合复位固定器 械。
为此， 本发明公开以下技术方案： 一种颞下颌关节盘缝合固定器械， 其特征在于， 包括第一缝合针和第一内芯、 第二缝合针和第二内芯和第三 缝合针， 其中，
所述第一缝合针的尾端通过管座连接大手柄， 大手柄表面向其圆心开 设一竖向凹槽， 在大手柄接近管座的地方有一条与竖向凹槽大小一致、 方 向垂直的横向凹槽， 所述第一内芯包括内径小于第一缝合针的无缝管， 无 缝管顶端悍接有呈两截突起的圈套钢丝， 接近尾端处成 90度弧度的转角， 尾端连接有小手柄， 所述第一内芯恰能从第一缝合针大手柄的竖向凹槽通 过， 尾端 90度转角的地方恰能向右或向左锁定在横向凹槽处， 顶端的圈套 钢丝恰能从第一缝合针顶端露出； 所述第二缝合针的尾端通过管座连接大 手柄， 大手柄表面向其圆心开设一竖向凹槽， 在大手柄接近管座的地方有 一条与竖向凹槽大小一致、 方向垂直的横向凹槽， 所述第二内芯包括内径 小于第二缝合针的无缝管， 无缝管顶端悍接有内径一致的钩针， 接近尾端 处成 90度弧度的转角， 尾端连接有小手柄， 所述第二内芯恰能从第二缝合 针大手柄的竖向凹槽通过，尾端 90度转角的地方恰能向右或向左锁定在横 向凹槽处， 顶端的钩针恰能从第二缝合针顶端露出； 所述第三缝合针为普 通 12号穿刺针。
所述圈套钢丝的第一截突起内径小于无缝管管体，第二截突起内径大于 无缝管管体； 所述钩针的钩内恰能容纳一根缝合线。
所述缝合线的基材采用聚酯纤维编织线 2-0，至少包括导引区和功能区， 所述导引区位于缝合线一端或两端， 经粘结剂处理加强硬度； 所述功能区 未经粘结， 保持原有的柔软度。 所述导引区和功能区可用不同颜色加以区 别。
本发明还可以在内芯尾端的小手柄中间有一小孔。
本发明具有以下有益效果：
第一、 第二缝合针上的大手柄便于手术操作， 其上与圆形通道垂直的 横向凹槽恰能卡住内芯，顶端带圈套钢丝的第一内芯替代了以往的结石钳， 更容易将缝合线与缝合针完全锁定， 手术时缝合线不易滑脱， 第二内芯顶 端的钩针恰能容纳缝合线， 从而将缝合线紧卡于钩针与缝合针之间， 手术 时能够将缝合线拉出， 而不易松脱， 本发明使手术能够一次性的顺利进行， 而不是反复重复一个手术动作， 大大减轻了患者的痛苦。 附图说明
下面结合说明书附图， 对本发明作进一歩详细说明。
图 1A是第一缝合针， 图 1B是第一内芯， 图 1C是第一缝合针和第一 内芯结合使用时的状态；
图 2A是第二缝合针， 图 2B是第二内芯， 图 2C是第二缝合针和第二 内芯结合使用时的状态；
图 3是第三缝合针；
图 4是第一内芯顶端圈套钢丝的放大图；
图 5是第二内芯顶端钩针的放大图。 具体实施方式
图 1A为第一缝合针， 由 12号穿刺针改制而成，在缝合针 9尾端通过管 座 3连接圆柱状的大手柄 1，大手柄 1表面向其圆心开设一竖向凹槽，在大 手柄 1接近管座 3的地方有一条与竖向凹槽大小一致、 方向垂直的横向凹 槽 2 ; 图 1B为第一内芯， 包括内径小于第一缝合针 9的不锈钢无缝管 10， 在无缝管 10顶端悍接有呈两截突起的具有弹性的圈套钢丝 4，在无缝管 10 接近尾端处成 90度弧度的转角 5，尾端连接有小手柄 7; 图 1C为第一缝合 针和第一内芯结合使用时的状态， 第一内芯恰能从第一缝合针大手柄 1 的 竖向凹槽穿过， 尾端 90度弧度转角 5的地方行至横向凹槽 2时， 恰能向右 或向左锁定在横向凹槽 2处， 内芯顶端的圈套钢丝 4恰能从缝合针 9顶端 露出。
图 4为圈套钢丝 4的放大图， 第一截突起 4a内径小于无缝管管体， 第 二截突起 4b内径大于无缝管管体， 圈套钢丝 4整体具有弹性， 第一截突起 4a较小的内径方便其从大手柄 1的底部圆形通道穿过，第二截突起 4b较大 的内径方便手术时穿过缝合线。 图 2A为第二缝合针， 也是由 12号穿刺针改制而成， 同样的， 在缝合针 11尾端通过管座 3连接圆柱状的大手柄 1， 大手柄 1表面向其圆心开设一 竖向凹槽， 在大手柄 1接近管座 3的地方有一条与竖向凹槽大小一致、 方 向垂直的横向凹槽 13， 与第一缝合针的不同点在于， 由于与之结合使用的 内芯 （图 1B、 图 2B) 顶端内径不一致， 所以缝合针、 竖向凹槽、 横向凹槽 的大小也相应的不同（第一缝合针 9的内径略大于第二缝合针 11的内径）， 其余都是相同的； 图 2B为第二内芯， 包括内径小于第二缝合针 11的不锈 钢无缝管 12， 在无缝管 12顶端悍接有内径一致的钩针， 在无缝管 12接近 尾端处成 90度弧度转角 5，尾端连接有小手柄 7; 图 2C为第二缝合针和第 二内芯结合使用时的状态， 第二内芯恰能从第二缝合针大手柄 1 的竖向凹 槽穿过， 尾端 90度弧度转角 5的地方行至横向凹槽 13时， 恰能向右或向 左锁定在横向凹槽 13处， 内芯顶端的钩针 6恰能从缝合针 11顶端露出。
图 5为钩针 6的放大图， 其钩内恰能容纳一根缝合线。
缝合线的基材采用安全可靠的聚酯纤维编织线 2-0， 至少包括导引区和 功能区， 导引区位于缝合线一端或两端， 经粘结剂处理加强硬度， 克服传 统缝合线较为柔软的不足，便于内镜下的操作，所述粘结剂为牌号为硅 288 的无毒粘结剂； 功能区未经粘结， 保持原有的柔软度， 利于打结及软组织 固定。 所述导引区和功能区可用不同颜色加以区别。
图 3为第三缝合针， 也是由 12号穿刺针改制而成。
作为本发明的一个优选实施例， 在小手柄 7上可以有小孔 8， 能增强本 发明的安全性， 手术时孔内穿过一细绳， 系于医生手上， 防止手术时缝合 器意外滑脱。 管座 3上也可以有一可视小孔， 便于观察内芯进入的情况。
本发明还可以增加一些人性化的细节： 大手柄 1 做成具有一定的粗糙 度， 在手术时防滑； 为了更方便的配套使用， 可以把相应配套的大手柄、 小手柄做成同一颜色， 手术时一目了然。
在使用时， （1 )先用第三缝合针（图 3 )按确定的穿刺点进入关节上腔， 此时助手持关节镜， 手术者于关节盘后带与双板区的交界线上， 由外向内 三等份的中外 1/3的交界点穿刺进入关节盘。 首先向下、 再向后内上方穿 入交界处组织， 并从中内 1/3的交界点穿出； （2 ) 嘱患者保持张口位， 助 手一只手持关节镜、 维持视野的稳定， 另一只手把第三缝合针（图 3) 向前 下抵在髁突后面、稳定关节盘； （3)手术者外耳道切口插入第一缝合针（图 1A) 及第一内芯 （图 IB), 注意缝合针慎勿穿破软骨， 将特制缝合线穿入， 调整针尖的位置， 将缝合线尖端穿过圈套钢丝 4， 第一内芯 （图 1B) 向右 或向左旋转 90° 锁定，将线收紧， 同时将第一缝合针（图 1A)的尖端后退， 便于圈套钢丝 4内的缝线从外耳道拉出， 拉出缝线、 半针缝合完毕； （4) 将第三缝合针（图 3)反方向退至关节盘的穿刺点， 再将其向后上推进至后 上隐窝， 调整缝线的长度， 助手将第三缝合针 （图 3 ) 向前下推压关节盘， 便于术者在外耳道切口穿刺第二缝合针 （图 2A), 第二内芯 （图 2B) 顶端 钩针 6钩住缝线、 将其导出关节腔至外耳道， 至此完成关节盘双线牵引缝 合固定术的第一针； （5 ) 内镜直视下检查关节盘复位的情况， 确定是否需 要继续缝针， 以及缝合的位置。
