  • Patent number: 9271749
    Abstract: An endoscopic medical device system includes an elongated shaft assembly, a cam assembly and an articulating distal end assembly. The elongated shaft assembly extends along a main axis and includes first and second actuator rods arranged parallel to each other and the first actuator rod is longer than the second actuator rod. The cam assembly includes a cam, and the proximal ends of the first and second actuator rods are configured to be slidably attached to first and second locations of the cam, respectively, and the distal ends of the first and second actuator rods are positioned at the same distance from the cam center. The articulating distal end assembly extends along the main axis and is pivotally connected to the distal ends of the first and second actuator rods. Rotation of the cam around an axis perpendicular to the main axis provides angular displacement of the distal end assembly relative to the main axis.

  • Patent number: 9044258
    Abstract: A laparoscopic instrument is disclosed, including an elongated tube defining a proximal portion and a distal portion; an end effector removably coupled to the distal portion, the end effector including first and second elements pivotably coupled to one another; an anchor coupled to the tube and a pivot point of the end effector to restrict axial movement of the end effector; and a sleeve movably coupled to the tube, where the sleeve is slidable across at least a portion of the end effector to secure the end effector to the tube.

  • Publication number: 20140171949
    Abstract: The present invention provides a linear slide indicator used in connection with a medical device to indicate radial expansion or linear translation of a component within the device. The medical instrument includes a shaft, a handle, an end effector and a linear slide indicator. The shaft extends along a shaft axis and is configured to travel linearly along the shaft axis. The handle is configured to be attached to a proximal end of the shaft and to rotate around the shaft axis. The end effector is configured to be attached to a distal end of the shaft and to travel linearly with the shaft along the shaft axis via the rotational motion of the handle. The linear slide indicator is configured to indicate a magnified value of an actual traveled linear distance of the end effector.
