    摘要: The present invention is directed to a tool having a wrist mechanism that provides pitch and yaw rotation in such a way that the tool has no singularity in roll, pitch, and yaw. In one embodiment, a minimally invasive surgical instrument includes an elongate shaft having a working end, a proximal end, and a shaft axis between the working end and the proximal end; and an end effector. A wrist member has a flexible tube including an axis extending through an interior surrounded by a wall. The wall of the flexible tube includes a plurality of lumens oriented generally parallel to the axis of the flexible tube. The wrist member has a proximal portion connected to the working end of the elongate shaft and a distal portion connected to the end effector.

    摘要: A cable guide re-orders a plurality of cables. A first guide plate has a plurality of first guide holes that receive a plurality of cables in a first order. A second guide plate has a plurality of second guide holes that receive the plurality of cables in a different second order. An intermediate guide plate is located between the first and second guide plates. The intermediate guide plate has a plurality of intermediate guide holes. Each of the intermediate guide holes receives one of the plurality of cables and causes a change of direction in the cable to facilitate the change from the first to the second order. The intermediate guide plate may further include cable passages to allow some cables to pass through without changing direction. There may be more than one intermediate guide plate. The cables may change from a generally linear to a generally circular arrangement.

    摘要: A force transmission transmits a force received by an input gimbal plate having two degrees of freedom to an output gimbal plate. The input gimbal plate is coupled to a first end of least three lever arms supported by a pivot. The output gimbal plate is coupled to a second end of the lever arms. The output gimbal plate may be coupled to the lever arms by flexible cables. The cables may be substantially contained within a tube. The output gimbal plate may be substantially smaller than the input gimbal plate. The force transmission may include a secondary output gimbal plate coupled to secondary levers that are coupled to the lever arms. The secondary levers may be third class levers. The secondary output gimbal plate may move proportionately to movement of the output gimbal plate. The force transmission may control a surgical end effector in a robotic surgical instrument.

    摘要: Medical, surgical, and/or robotic devices and systems often including offset remote center parallelogram manipulator linkage assemblies which constrains a position of a surgical instrument during minimally invasive robotic surgery are disclosed. The improved remote center manipulator linkage assembly advantageously enhances the range of instrument motion while at the same time reduces the overall complexity, size, and physical weight of the robotic surgical system.
