    • A robotic tool changer ensures inherently safe operation by separating power sources for the “couple” and “decouple” operations of its coupling mechanism. The power for the decouple operation is available only when an attached robotic tool is safely disposed in its tool stand. Once the robotic tool leaves the tool stand, there is no power supplied to the coupling mechanism of the robotic tool changer to decouple the robotic tool from a robot arm. Accordingly, it is impossible for the robotic tool to inadvertently become disengaged from the robot arm—even if software were to erroneously assert a DECOUPLE signal, or otherwise initiate a decouple operation. Furthermore, since the design is inherently safe, neither interlock circuits, the redundancy of such circuits, nor the extensive and complex monitoring circuits necessary to ensure their proper operation, are necessary.
    • 机器人换刀器通过分离其联接机构的“耦合”和“去耦”操作的电源来确保本质安全的操作。 只有当连接的机器人工具安全地放置在其工具架上时,解耦操作的电源才可用。 一旦机器人工具离开工具架,则没有电源供给机器人工具更换器的联接机构,以将机器人工具与机器人手臂分离。 因此,机器人工具不可能无意中脱离机器人臂 - 即使软件错误地声明了DECOUPLE信号,或者以其他方式启动解耦操作。 此外,由于设计本质上是安全的,所以不需要互锁电路,这种电路的冗余以及确保其正常工作所必需的广泛和复杂的监控电路。

    • The present invention is directed to a tool holder for use with a surgical robot. The tool holder includes, a rotor fixed to the tool shaft, and a stator fixed to the robot. The stator includes a magnet, and a bearing surface. The rotor includes a magnetic material that attaches securely to the tool shaft, such that the tool is in the center of the rotor. The rotor rotates against the bearing surface on the stator, allowing the tool to rotate about its axis. To exchange tools, the user exerts force on the tool until the holding force of the magnet is exceeded and the tool detaches from the stator. A new tool is introduced into the vicinity of the stator such that the magnet attracts the magnetic material on the rotor. The present invention eliminates the need to slide the tool through a shaft of the tool holder.
    • 本发明涉及一种与外科手术机器人一起使用的刀架。 工具架包括固定在工具轴上的转子和固定在机器人上的定子。 定子包括磁体和支承面。 转子包括牢固地附接到工具轴的磁性材料,使得工具位于转子的中心。 转子抵靠定子上的支承表面旋转,允许工具绕其轴线旋转。 为了更换工具,用户对工具施加力,直到超过磁体的保持力,并且工具与定子分离。 将新工具引入定子附近,使得磁体吸引转子上的磁性材料。 本发明消除了将刀具滑过刀架的轴的需要。
