现在，将参照附图更详细地描述根据本发明的示例性实施例。然而，这些示例性实施例可以多种不同的形式来实施，并且不应当被解释为只限于这里所阐述的实施例。应当理解的是，提供这些实施例是为了使得本发明的公开彻底且完整，并且将这些示例性实施例的构思充分传达给本领域普通技术人员。
如图1、图2、图3及图4所示，本发明实施例提供了一种超声刀，包括驱动柄8、刀头组件1及中空电机4；刀头组件1包括刀杆101及设置在刀杆101一端的刀头102，刀杆101的另一端设有空腔，驱动柄8上靠近刀杆101的一端设有外螺纹，空腔内设有与外螺纹适配的内螺纹；中空电机4的内部设有能够使刀杆101穿过的通道，在刀杆101能够穿过中空电机4的情况下，中空电机4能够带动刀杆101旋转。
在具体应用中，该超声刀还包括壳体3，驱动柄8设置外螺纹的一端伸入至壳体3内，驱动柄8上还设有与主机连接的驱动柄电源线6，以为驱动柄8提供工作电压。壳体3上还设有开关5，以控制中空电机4的开闭；具体地，操作者向一侧拨动开关5时，中空电机4沿第一方向旋转，操作者向另一侧拨动开关5 时，中空电机4沿第二方向旋转(第一方向与第二方向相反)，而开关5位于中间位置时，则中空电机4停止转动。
中空电机4的整体外形可采用圆柱体、长方体等结构，本实施例不做严格限定。中空电机4可以设置在壳体3内，也可以直接套设在刀杆101上。
在安装刀杆101时，如果中空电机4安装在壳体3上，操作者先将刀杆101设置空腔的一端穿过中空电机4的通道，并使驱动柄8上的外螺纹与空腔内的内螺纹接触，然后向一侧拨动开关5开启中空电机4，通过中空电机4带动刀杆101转动，使刀杆101与驱动杆螺纹连接，从而实现了刀杆101与驱动杆的组装。如果中空电机4直接套设在刀杆101上，操作者直接将刀杆101上的空腔内的内螺纹与驱动柄的外螺纹接触，然后拨动开关5开启中空电机4，通过中空电机4带动刀杆101转动，使刀杆101与驱动杆螺纹连接，从而实现了刀杆101与驱动杆的组装。在拆卸刀杆101时，操作者向另一侧拨动开关5开启中空电机4，通过中空电机4带动刀杆101转动，使刀杆101与驱动杆拧开，然后就可将刀杆101卸下，由此该超声刀通过中空电机4带动刀杆101的旋转就可实现刀杆101的装卸，从而便于操作者对刀杆101与驱动杆的组装。
可以理解的是，操作者可根据内螺纹及外螺纹的盘旋方向及装卸刀杆101的操作，来确定中空电机4的旋转方向，从而确定开关5的拨动方向。
在现有技术中，当使用超声刀时，当操作者通过刀头102夹紧血管等生物组织之前，往往还需要将调整刀头102的角度，以满足能够顺利的夹紧生物组织。操作者以手动方式旋转超声刀，会由于手部疲劳等因素，导致操作者的力度及旋转角度等无法精确的控制，从而造成手术的精准程度不高。而在本实施例中，在使用超声刀前，操作者根据生物组织的位置，可通过拨动开关5来开启中空电机4，从而带动刀杆101旋转，以能够顺利的夹紧生物组织，这样无需操作者手动旋转刀头102，不仅便于操作者的操作，而且转动角度及力度控制的更加准确。具体中空电机4的旋转方向可通过刀头102的旋转方向来确定，以此也可确定操作者拨动开关5的方向。
本实施例所提供的一种超声刀，刀杆101设置空腔的一端穿过中空电机4，使驱动柄8的外螺纹与空腔内的内螺纹接触，然后启动中空电机4带动刀杆101旋转，使刀杆101与驱动柄8螺纹连接，从而无需操作者手动旋转刀杆101，省时省力。
在另一些实施例中，如图1和图5所示，刀杆101上靠近刀头102的部分还设有摄像组件2，摄像组件2包括摄像部203、驱动部201及传动部202，摄像部203通过传动部202与驱动部201连接，驱动部201通过传动部202带动 摄像部203绕刀杆101转动。
其中，驱动部201可采用马达，当然可以采用现有的其他驱动部件，本实施例不做严格限定。在刀杆101的一侧还设有导线及视频传输线套管10，以容置驱动部201及摄像部203所连接的导线及视频传输线9。
在本实施例中，在刀杆101靠近刀头102的部分设置摄像组件2，并且驱动部201通过传动部202带动摄像部203绕刀杆101转动，也就是说通过驱动部201及传动部202之间的传动动作能够调整摄像部203的位置，从而操作者可根据实际需求，利用驱动部201及传动部202将摄像部203旋转至需观察的位置，以通过摄像部203看到所要观察的位置的图像，这样不仅提高摄像部203的拍摄范围，并且也无需其他人配合来调整内窥镜的位置，节省人力。
值得注意的是，摄像部203还会随着刀杆101的转动而转动，也就是说在需要小范围调整摄像部203的位置时，操作者可通过中空电机4带动刀杆101转动，从而带动摄像部203转动，以转到目标位置。
具体地，如图6和图7所示，传动部202包括设置在刀杆101外部的转动套体2023，转动套体2023内设有动齿轮2022及与静齿轮2021，静齿轮2021套设在刀杆101的外部，驱动部201安装在转动套体2023上，且驱动部201与动齿轮2022连接；摄像部203设在转动套体2023的外壁上。
在调整摄像部203的位置时，驱动部201开启，通过驱动部201的旋转来带动动齿轮2022的旋转，从而使动齿轮2022绕静齿轮2021外周转动，进而带动转动套体2023相对于静齿轮2021转动，也就是转动套体2023相对于刀杆101转动，这样就能够带动设置在转动套体2023上的摄像部203围绕刀杆101转动，从而调整摄像部203的位置。
进一步地，为了避免驱动部201及摄像部203所连接的导线及视频传输线9出现相互缠绕的情况，摄像部203绕刀杆101旋转的角度为360°，也就是说摄像部203仅能绕刀杆101旋转一周，在摄像部203绕刀杆101旋转一周之后，摄像部203仅能沿相反方向旋转，而不能沿原方向继续旋转。
进一步地，如图7所示，摄像部203与转动套体2023可拆卸连接，从而便于摄像部203的维护、消毒或更换的操作。
具体而言，摄像部203包括第一螺栓2025、摄像头2031以及套设在摄像头2031外部的抱箍2032，抱箍2032设有与螺栓相适配的第一螺孔，转动套体2023上均设有与螺栓相适配的第二螺孔2024，第一螺孔通过第一螺栓2025与第二螺孔2024连接。
在安装摄像部203时，将第一螺栓2025穿过第一螺孔及第二螺孔2024，然 后将第一螺栓2025拧紧，这样抱箍2032就能够夹紧摄像头2031，并且抱箍2032也与转动套体2023连接紧固，从而实现了摄像部203与转动套体2023的组装。在卸下摄像部203时，将第一螺栓2025拧下，就可将抱箍2032与转动套体2023分离，从而将摄像头2031卸下。
进一步地，如图7所示，第二螺孔2024的数量至少为两个，至少两个第二螺孔2024沿转动套体2023的轴向由上至下依次设置，这样操作者可通过第一螺栓2025将第一螺孔与不同高度的第二螺孔2024连接，从而调整抱箍2032的高度，进而调整抱箍2032夹持的摄像部203的高度。
在本实施例中，通过调整摄像部203的高度，从而能够满足手术中不同的观察需求，提供了超声刀的适应性。
进一步地，如图7所示，转动套体2023包括第一盖体20231、第二盖体20233及周壁20232，周壁20232分别与第一盖体20231及第二盖体20233可拆卸连接。
通过拆卸第一盖体20231及第二盖体20233，从而可将位于转动套体2023内的动齿轮2022以及转动套体2023上的驱动部201拆卸下来，进而便于对静齿轮2021及驱动部201进行维护、消毒或更换。
进一步地，超声刀还包括第二螺栓及第三螺栓；周壁20232的一端面设有与第二螺栓相适配的第三螺孔，周壁20232的另一端面设有与第三螺栓相适配的第四螺孔，第一盖体20231上设有与第三螺栓相适配的第五螺孔，第二盖体20233上设有与第三螺栓相适配的第六螺孔；第三螺孔通过第二螺栓与第五螺孔连接，第四螺孔通过第三螺栓与第六螺孔连接。
可以理解的是，第三螺孔及第四螺孔可以连通，即贯穿周壁20232；也可以不连通，即具有一定深度，能够使第二螺栓及第三螺栓伸入即可。
在需要拆卸静齿轮2021及驱动部201时，第二螺栓及第三螺栓拧下，然后就可将第一盖体20231及第二盖体20233卸下，之后就可将驱动部201及马达卸下。
在上述实施例中，中空电机4可采用下面两种方式获得电能。
第一种方式，在驱动柄8及刀杆101上均设有导电端；在驱动柄8与刀杆101连接的情况下，驱动柄8的导电端与刀杆101内的导电端接触，以将驱动柄8的电能通过刀杆101传递给中空电机4，以为中空电机4供电。
在该种方式中，可以省去为中空电机4单独供电的部件，如电机电源线7等，从而使得整个器械的结构更加紧凑，并且操作起来更轻便。
第二种方式，如图7所示，超声刀还包括与中空电机4连接的电机电源线7。
该种实现方式能够简化整个器械的结构，便于制作。
本发明已经通过上述实施例进行了说明，但应当理解的是，上述实施例只是用于举例和说明的目的，而非意在将本发明限制于所描述的实施例范围内。此外本领域技术人员可以理解的是，本发明并不局限于上述实施例，根据本发明的教导还可以做出更多种的变型和修改，这些变型和修改均落在本发明所要求保护的范围以内。本发明的保护范围由附属的权利要求书及其等效范围所界定。
