Description

超声医疗器械和医疗器械连接组件
技术领域
本发明整体上涉及医疗器械，更具体而言，本发明涉及一种超声医疗器械和一种医疗器械连接组件。
背景技术
已知的医疗器械包括手持件和医疗超声刀组件。手持件包括超声换能器。该组件的超声刀在靠近振动腹点处与该组件的手持件物理接触，并且仅通过螺纹连接(刀上的内螺纹和手持件上的外螺纹)连接到该组件的手持件上。这需要多次旋转以安装刀，需要转矩限制装置来正确地安装刀，并且螺纹易于剥离或损坏。已知的快速连接方式使刀在振动腹点处接触手持件，并且在振动节点处提供力以将两个构件保持在一起。这对于较大范围的输入来说无法可靠地工作并且不能实施。
科学家和工程师仍然在探寻改进的手持件和医疗超声刀组件，以及改进的医疗器械连接组件。
发明内容
本发明的一种实施方式的第一种表现形式是一种超声医疗器械，其包括手持件和医疗超声刀组件。所述手持件和医疗超声刀组件包括：振动腹点、手持件和医疗超声刀。所述医疗超声刀在靠近所述振动腹点处能与所述手持件螺纹接合。所述医疗超声刀在靠近所述振动腹点并且远离所述医疗超声刀与所述手持件螺纹接合的位置处与所述手持件超声传输物理接触。
本发明的一种实施方式的第二种表现形式是一种用于传输超声振动的医疗器械连接组件，其包括：超声医疗器械第一连接构件、超声医疗器械第二连接构件和超声医疗器械第三连接构件。所述第一连接构件能够超声振动并且具有纵向轴线。所述第二连接构件能够被定位成与所述纵向轴线基本上共轴对准并且与所述第一连接构件超声传输物理接触。所述第三连接构件围绕且可旋转地或固定地安装到所述第二连接构件上，并且能与所述第一连接构件螺纹接合。
从本发明的一种实施方式的一种或多种表现形式可以获得若干益处和优点。在一个例子中，在靠近纵向振动腹点处进行物理接触和螺纹接合(手持件上的内螺纹作用在刀的外径上)能提供改进的超声转换，而在远离物理接触处沿径向螺纹接合则允许快速连接(和拆开)，而不需要多次旋转或转矩限制装置，同时能减小剥离或损坏螺纹的可能性。
