  • Patent number: 8602288
    Abstract: A surgical tool for use with a robotic system includes an end effector comprising at least one component portion selectively movable between first and second positions and a shaft including an axially movable portion in operable communication with the at least one selectively movable component portion and a rotatably movable portion in operable engagement with the axially movable portion. An initial rotation of the rotatably movable portion causes the axially movable portion to move the selectively movable component portion from the first position into an intermediate position at a first rate. A subsequent rotation of the rotatably movable portion in a same direction causes the axially movable portion to move the selectively movable component portion from the intermediate position to the second position at a second rate different from the first rate.

  • Patent number: 8393514
    Abstract: A fastener cartridge can comprise a compressible, collapsible, and/or crushable cartridge body and fasteners embedded within the cartridge body which can be utilized to fasten tissue. In use, the fastener cartridge can be positioned in a first jaw of a surgical fastening device, wherein the first jaw can be positioned opposite a second jaw, or anvil. The anvil can be engaged with the fastener cartridge to compress, collapse, and/or crush the cartridge body and deform, or otherwise deploy, the fasteners contained therein. As the fasteners are deformed or deployed, the fasteners can capture at least a portion of the cartridge body therein along with at least a portion of the tissue being fastened. In various embodiments, the fastener cartridge and/or the first jaw can comprise retention features which can allow the fastener cartridge to be selectively inserted into the first jaw in a first orientation or a second orientation.

  • Patent number: 8179074
    Abstract: Methods and devices are provided for rotating an end effector on a long, flexible medical device. The methods and devices utilize an actuator mechanism that is effective to rotate an end effector on the distal end of an elongate flexible shaft. The actuator mechanism is movable between a freely rotatable position and a rotationally resistant position. When the actuator mechanism is in a freely rotatable position, the actuator mechanism can be rotated to impart torque to the end effector, and thus at least a distal portion of the elongate shaft, to cause the end effector to rotate. In order to prevent the actuator mechanism from “freewheeling,” wherein the actuator mechanism freely rotates in an opposite direction upon release rather than the end effector rotating in the desired direction, the actuator mechanism can be moved to the rotationally resistant position.

  • Patent number: 7905902
    Abstract: The present invention provides a surgical implant which can be made of a metal that corrodes while implanted in tissue of a patient. The surgical implant has a preferential corrosion zone adapted to corrode at a different rate than the rest of the surgical implant. In one embodiment, the surgical implant is surgical staple that may be formed into a “B-shape” when deployed into tissue, although the invention also is applicable to many other kinds of staples, clips, and other metallic surgical implants. In one embodiment, the preferential corrosion zone comprises an indentation that provides a site for crevice corrosion.

  • Patent number: 7819877
    Abstract: A bone plating apparatus includes a handle having extending therefrom a tissue expander for insertion through a skin incision and through the subcutaneous tissue surrounding a fractured bone. A bone plate may be secured to the handle during advancement of the tissue expander so as to deliver the bone plate to a desired location proximate to the fractured bone. Both the tissue expander and the bone plate may be advanced to the desired location proximate to the fractured bone under the visualization of an endoscope. A screw alignment jig is secured to the handle and has a guide hole which aligns with an access hole of the tissue expander. The alignment of the guide hole and the access hole allow for percutaneous screw insertion into the delivered bone plate. A method for plating a fractured bone is also disclosed.
