具体实施方式
下面将结合附图对本发明的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域 的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
下面通过具体的实施例子并结合附图对本发明做进一步的详细描述。
图2A为本发明的超声骨刀刀头的第一实施方式的立体示意图，图2B为本发明的超声骨刀刀头的第一实施方式的主视图，图2C为本发明的超声骨刀刀头的第一实施方式的俯视图。如图2A～图2C所示，本发明第一方式的超声骨刀刀头包括刀头头部1、刀杆2和刀身3，刀杆2的一端和刀头头部1连接，刀杆2的另一端和刀身3连接，刀头头部1形状为扁平片形，刀头头部1的顶端11为弧形，在刀头头部1的其中一个侧表面设置有齿状结构12。优选地，可以在刀头头部1的一个侧表面设置多个弧形凹槽以形成齿状结构12。弧形顶端11为光滑面。刀头头部1设置有齿状结构12的侧表面与顶端11平滑过渡，不存在棱角。
如图2A所示，本实施方式所涉及的超声骨刀刀头在所述刀头头部1的顶端11设置有相比于所述刀头头部的其他部分厚度变厚的加厚部。也就是说，所述刀头头部的顶端11的厚度比刀头头部的其他部位的厚度厚。在刀头头部1中靠近顶端11的加厚部的位置设置有导流凹部13，如图2B所示。导流凹部13能够确保将水流引导到刀头头部的手术切割面并保证手术部位有足够的水流，从而有效地对刀头进行冷却。手术时，使整个刀头头部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，且能够保护需要保留的组织不被损伤。这样能够使手术风险进一步降低，手术安全性成功率得到提高。
如图2A～图2C所示，本发明的超声骨刀刀头中，刀杆2和刀身3均呈圆柱体形状，刀杆2外径小于刀身3外径，刀杆2和刀身3之间通过斜面或圆弧平滑过渡。平滑过渡的结构可以有效地防止应力集中，同时防止尖锐边角对接受手术者和操作人员的伤害。另外，也可以是在刀身3上设置有用于进行夹持的夹持面31，如此能够方便操作人员采用夹持工具对夹持面31进行夹持，而将本发明的超声骨刀刀头旋紧在换能器上。优选为，夹持面31是正六角扳手位。
本发明的超声骨刀刀头中，在刀身3设置有连接机构。优选地，该连接机构为螺纹结构，该螺纹结构可以是外螺纹也可以是内螺纹。当然连接机构并不仅局限于螺纹结构，只要是能够将本发明的超声骨刀刀头以一种可拆卸的方式固定在换能器上的任何连接机构都可设置在本发明的超声骨刀刀头的刀身上。将本发明的超声骨刀刀头的刀身的连接螺纹与特定的超声换能器连接，并用相应的扳手拧紧，再将超声换能器连接于特定的超声主机，即可进行工作。
图3A为本发明超声骨刀刀头的第二实施方式的立体示意图，图3B为本发明超声骨刀刀头的第二实施方式的主视图，图3C为本发明超声骨刀刀头的第二实施方式的俯视图。如图3A～图3C所示，作为本发明的第二实施方式所涉及的超声刀刀头，在刀头头部1的另一侧表面即与上述设置有齿状结构12的侧表面相对称的侧表面上也设置有齿状结构12，也就是说刀头头部1的两个侧表面均设置有齿状结构12。这样能够给医生提供另一种切割操作方式，操作性更强。
图4为本发明超声骨刀刀头的第三实施方式的主视图。本发明超声骨刀刀头的第三实施方式所涉及的超声骨刀刀头中，也可以在刀头头部1设置有导流长槽14，导流长槽14的一端与导流凹部13相连通，导流长槽14的一端另一端向刀杆2的方向延伸。导流长槽14的存在能够确保将更加大量的水流引导到刀头头部的手术切割处，为刀头的手术部位提供更加充分的冷却。手术时，使整个刀头头部和接触到的组织实时地完全处于灌注液的清洗和冷却中，确保被切除的骨屑能够更加即时地排出，切口处视野更加清晰洁净，进一步提高手术过程中的清洗和冷却效果。
图5为本发明超声骨刀刀头的第四实施方式的主视图。本发明超声骨刀刀头的第四实施方式所涉及的超声骨刀刀头是在本发明第二实施方式所涉及的超声骨刀刀头的基础上，在刀头头部1设置导流长槽14，导流长槽14的一端与导流凹部13相连通，另一端向刀杆2的方向延伸。导流长槽14的存在能 够确保将更加大量的水流引导到刀头头部的手术切割处，进一步提高手术过程中的清洗和冷却效果。所述刀杆和刀身也可以做成中心具备沿轴线延伸的贯通孔的中空结构，所述导流长槽14与具有中空结构的刀杆的出水口相连通。
图6为本发明超声骨刀刀头的第五实施方式的主视图。本发明超声骨刀刀头的第五实施方式所涉及的超声骨刀刀头是在本发明第一实施方式所涉及的超声骨刀刀头的基础上，对刀头头部1的没有形成齿形结构的一个侧面进行减薄开刃，形成减薄部15。这样能够给医生提供另一种切割操作方式，操作性更强。
与现有技术相比，本发明实施例的优点在于：本发明中的超声骨刀刀头可以将超声换能器所产生的能量全部汇聚于刀前端部分(最有效的工作部分)，使刀具的刀顶端部分具有最强的能量输出，达到最强的工作效果。刀头头部顶端采用弧形结构，能够有效避免顶端对组织的刮划，从而提高了手术的安全性。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
