下面将参照附图来说明根据本发明的一个实施例的超声骨刀刀头 100, 其中图 3是本发 明的一个实施例的超声骨刀刀头 100的立体结构示意图。 图 4是本发明的一个实施例的超 声骨刀刀头 100的俯视图。 图 5是本发明的一个实施例的超声骨刀刀头 100的主视图。 图 6 是图 3中的部分 B的局部放大结构示意图。
如图 3中所示, 根据本发明的一个实施例, 超声骨刀刀头 100可以包括: 刀头端部 1和 刀杆 2。 刀头端部 2与刀杆 1的前端相连, 其中所述刀头端部 2呈匙形且前部边缘为齿状。 这样的设计使得切割速度更快, 从而降低手术时间, 而且切割时定位准确, 不打滑, 能够 提高手术成功率。 如图 3中所示, 刀身 3和刀杆 2连接, 刀杆 2为细圆柱段, 刀身 3为粗圆柱段, 刀身 3 和刀杆 2之间圆弧过渡, 刀身 3设置有扳手位 5, 刀身 3的主体上与所述刀杆 2相对的一侧 形成有螺纹连接孔 4, 螺纹安装孔 4用于与超声换能器(未示出)进行螺纹安装连接。 在需 要使用时, 利用本刀头后端的螺纹连接孔 4 与特定的超声换能器连接, 并用相应的扳手在 扳手位 5拧紧, 再将超声换能器连接于特定的超声主机, 即可进行超声切割。
根据本发明的一个实施例, 超声骨刀刀头 100 的刀头端部 1 的前部边缘处的最大宽度 D2不小于刀杆 2的宽度 Dl。 这种结构的好处在于当使用时刀头端部 1切割出的宽度就大于 或等于刀杆 2 的直径。 在手术过程中, 切割较厚的骨头或切割较深的槽、 窗型切口时, 就 能避免出现夹刀卡死现象, 同时还能确保灌注水流流至刀头端部切割处, 保证切口不会被 灼伤。
根据本发明的一个实施例,超声骨刀刀头 100的刀杆 2和刀头端部 1内部可以为中空结 构且相互连通。 刀头端部 1 的孔口可以位于匙心。 这种设计增加的好处在于, 匙心单出口 的超声骨刀刀头可确保灌注液由刀身通过中空结构而流动至匙心处并流出, 手术时使匙心 及整个刀头端部 1 和接触到的组织实时地完全处于灌注液的清洗和冷却中, 确保被切除的 骨屑即时排出, 切口处视野清晰洁净, 且保护剩余要保留组织不被损伤, 在刮削操作时体 现尤为明显, 这样就使手术风险进一步降低, 手术安全性、 成功率得到提高。
根据本发明的一个实施例,超声骨刀刀头 100的刀杆 2和刀头端部 1内部可以为中空结 构且相互连通。 刀头端部 1的孔口 6可以位于匙心 (相当于凹面上设有孔口 6), 如图 6中 所示。 这种设计增加的好处在于, 匙心单出口的超声骨刀刀头可确保灌注液由刀身通过中 空结构而流动至匙心处并流出, 手术时使匙心及整个刀头端部 1 和接触到的组织实时地完 全处于灌注液的清洗和冷却中, 确保被切除的骨屑即时排出, 切口处视野清晰洁净, 且保 护剩余要保留组织不被损伤, 在刮削操作 (如图 9中 F4所示) 时体现尤为明显,, 这样就 使手术风险进一步降低, 手术安全性、 成功率得到提高。
根据本发明的一个实施例, 孔口 6也可以设置在匙底 (相当于凸面上设有孔口 6)。 根 据本发明的一个实施例, 刀头端部 1的孔口 6可以有两个, 分别位于匙心和匙底。 这种设 计增加的好处在于, 匙心匙底双出口的超声骨刀刀头 100 可确保灌注液由匙心和匙底处同 时流出, 手术时使匙心和匙底及整个刀头端部和接触到的组织实时的完全处于灌注液的清 洗和冷却中, 确保被切除的骨屑即时排出, 由于有上下两处出水, 在任何切除操作时都能 使切口处视野清晰洁净, 且更加有利保护剩余要保留组织不被损伤, 在将匙形刀头端部伸 进硬脊膜与要去除的椎体 (骨头) 之间, 用力的方向由内向外进行操作时, 这种类型尤为 重要, 因为匙底处的出水对处于匙底下方的硬脊膜及脊髓进行保护, 匙心处出水对匙心上 方的组织进行保护。 另外还有, 在手术时有一处出水口被堵或被阻时, 另一处还能保证液 流的充分流出提供保护。 再有, 两处出水使液流流至组织更加充分。 综上, 这样就使手术 风险更加进一步降低, 手术安全性、 成功率得到更进一步提高。
根据本发明的一个实施例,刀头端部 1的所述前部边缘大致沿所述刀头端部 1的凹面朝 向凸面的方向形成有多个齿槽 7。每个所述齿槽 7大致与刀头端部 1的凹面朝向凸面的方向 的夹角小于 90度。 如图 6中所示, 齿槽 7的一端与刀头端部 1的凹面相连通, 齿槽 7沿着 所述方向的长度 L1 自中间向两侧逐渐变小。可以用相邻齿槽 7之间的不同尺寸的齿来进行 手术操作, 方便手术人员进行选择。
在本发明的一些实施例中, 如图 7中所示, 刀头端部 2的与凸面和凹面相连的两个相对 侧壁中的至少一个上设有多个间隔开的第一凹槽 12, 多个第一凹槽 12限定出摩擦花纹, 从 而使得超声骨刀刀头 100可起到磨骨的作用, 且可采用刀头端部 2的侧壁对骨头进行切割, 提高超声骨刀刀头 100的使用便利性。 优选地, 每个第一凹槽 12在从匙心到匙底的方向上 延伸, 且多个第一凹槽 12在从前到后的方向上分布, 从而可以增加第一凹槽 12的数量, 提高侧壁的磨切效果。
当然, 刀头端部 2的凸面上也可以设有多个第二凹槽 (图未示出), 多个第二凹槽限定 出摩擦花纹, 从而可以进一步提高超声骨刀刀头 100 使用的便利性, 优选地, 每个第二凹 槽在刀头端部 2的宽度方向上延伸, 多个第二凹槽在从前到后的方向上分布。
下面将参照附图 8、 9来描述根据本发明的实施例的超声骨刀刀头的操作。 在操作根据 本发明的一个实施例的、 刀头端部为匙形的超声骨刀刀头 100 时, 利用匙子的使用原理, 匙形刀头端部 1 的任意部位都可对骨头 200进行去除操作, 操作者可任意选择适合自己想 要进行的手法、 姿势使用, 没有操作上的局限性, 方便使用, 在使用时可将匙形刀头端部 1 伸进硬脊膜与要去除的椎体 (骨头) 之间, 用力的方向由内向外进行操作, 如图 8中所示, 这样就减小了对脊 (骨) 髓等的软组织 300 意外破坏损伤的危险, 降低了手术风险, 减少 了操作难度。 同时在手术过程中, 通过空口 6流出灌注液进行清洗和冷却, 从而使匙心 /匙 底及整个刀头端部 1 和接触到的组织实时地完全处于灌注液的清洗和冷却中, 确保从骨头 200切除的骨屑 (未示出) 即时排出, 切口处视野清晰洁净, 且保护剩余要保留组织不被损 伤。
根据本发明的一个实施例, 进一步提供了一种包括如上所述的超声骨刀刀头的超声骨 刀。 根据本发明的超声骨刀设计, 不仅切割速度更快, 降低手术时间, 而且切割时定位准 确, 不会发生打滑现象, 从而能够提高手术的成功率。
在本说明书的描述中, 参考术语 "一个实施例"、 "一些实施例"、 "示意性实施例"、 "示 例"、 "具体示例"、 或 "一些示例"等的描述意指结合该实施例或示例描述的具体特征、 结 构、 材料或者特点包含于本发明的至少一个实施例或示例中。 在本说明书中, 对上述术语 的示意性表述不一定指的是相同的实施例或示例。 而且, 描述的具体特征、 结构、 材料或 者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施例, 本领域的普通技术人员可以理解: 在不脱 离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、 修改、 替换和变型, 本发明的范围由权利要求及其等同物限定。
