    摘要: A surgical end effector includes a clevis having a first end to be supported by an elongated tube-like member and two jaws, each having a pivot portion and a working portion. The pivot portions are rotatably coupled to the clevis by two spaced apart pivots. The working portions may include a cutting edge that provide a shearing action as the first and second jaws rotate about their respective pivots. The pivot portion and the working portion of each jaw may be on opposite sides of a bisecting plane. A flexible cable or wire may be coupled to each jaw and extend through a guide way in the other jaw, between the first and second pivots, and through the first end of the clevis. One or more springs may urge the working portions together. A rocking pin pivotally supported by the clevis may constrain the jaws to have opposite motions.

    摘要: A surgical end effector includes a clevis and two jaws pivotally coupled to the clevis. A wire is coupled to each jaw and extended through a guide way in the other jaw and through an end of the clevis. The jaws may be opened and closed by pushing and pulling on the two cables. Pulling on each wire creates a closing force in both jaws. A rocking pin may be pivotally supported by the clevis and pivotally coupled to the jaws to constrain the jaws to have opposite motions. The clevis may be coupled to an elongate shaft and the wires extended through the shaft to provide an endoscopic instrument. A wire guide may support the wires in the shaft such that they are able to transmit a compressive force without buckling. The wires may carry electricity to the jaws for electrocautery.

    摘要: In one embodiment of the invention, a robotic arm is provided including a linkage assembly and a strap drive train. The linkage assembly includes first, second, third, and fourth links pivotally coupled in series together at first, second, and third joints to define a parallelogram with an insertion axis. The strap drive train includes first and second sets of straps coupled to the linkage assembly. As the linkage assembly is moved about a pitch axis, the first set of straps ensures the third link maintains the same angle relative to the first link, and the first and second set of straps ensures the fourth link maintains the same angle relative to the second link.

    摘要: A overload protection mechanism protects a driven load, such as a driven lever. An overload lever is pivotally coupled to a first part of the driven load. The overload lever has a first end that receives an applied force and an opposing second end. A zero length spring mechanism is coupled to a second part of the driven load spaced apart from the first part and to the second end of the overload lever. The zero length spring mechanism urges the second end of the overload lever toward the second part of the driven load with a force that is substantially proportional to the distance between the second end of the overload lever and the second part of the driven load. A stop mechanism is coupled to the zero length spring mechanism to maintain a minimum distance between the second end of the overload lever and the second part of the driven load.
