  • Patent number: 11980392
    Abstract: A depth limiter that is configured to couple with a cannula tube of a trocar. The depth limiter includes a body having first and second body portions coupled together and pivotable between open and clamped configurations. The body includes first and second inner surfaces presented by the first and second body portions. In the clamped configuration the first and second inner surfaces form a first cross dimension sized to restrict axial movement of the depth limiter relative to the cannula tube. In the open configuration the first and second inner surfaces form a second cross dimension sized to permit axial movement of the depth limiter relative to the cannula tube. The depth limiter includes first and second locking members, one of which is resiliently biased to engage the other. The locking members are configured to engage each other to lock the body portions in the clamped configuration.

  • Publication number: 20230225760
    Abstract: A depth limiter that is configured to couple with a cannula of a surgical access device. The depth limiter includes first and second user contact portions and first and second biasing features. The first biasing feature includes a first resilient portion and a first gripping surface. The second biasing feature includes a second resilient portion and a second gripping surface. The first and second resilient portions are configured to move the respective first and second gripping surfaces from a fixed configuration to a movable configuration when the respective first and second user contact portions are actuated. In the fixed configuration, the first and second gripping surfaces collectively restrict axial movement of the depth limiter by directly contacting the cannula. In the movable configuration, the first and second gripping surfaces extend parallel to a longitudinal axis and allow for axial movement of the depth limiter relative to the cannula.

  • Patent number: 10239124
    Abstract: A cutting insert including a body having three vertices, an upper face, a lower face, and flank faces joining the upper and lower faces. At least one cutting edge is formed at an intersection between the upper face and the flank faces. A generally triangular-shaped island surrounds a central axis of the cutting insert and is higher in elevation than at least one portion of the upper face.

  • Patent number: 10005131
    Abstract: A cutting insert includes a body having three vertices, an upper face, a lower face, and six planar flank faces perpendicular to and joining the upper and lower faces. A cutting edge is formed at an intersection between the upper and lower faces and each of the planar flank faces. A triangular-shaped island surrounds a central axis, A, of the cutting insert and is higher in elevation than the upper and lower faces. A tool holder includes a tool holder body having a generally triangular-shaped insert-receiving pocket with a triangular-shaped recess that is substantially identical in shape to the triangular-shaped island of the cutting insert that interacts with the island to properly locate and prevent rotation of the cutting insert when mounted in the tool holder.

  • Publication number: 20150283619
    Abstract: A tool holder includes a body having a forward end with a clamp seating surface, and a clamp mounted on the clamp seating surface with an integrated insert-receiving pocket for receiving a cutting insert. The insert-receiving pocket is formed by a pair of side walls formed at an angle with respect to each other, depending on the shape of the cutting insert. A slot is formed in side walls to allow the clamp to act as a cantilevered member when a clamp screw is received in an insert screw, thereby causing the clamp to press against the cutting insert to securely hold the cutting insert in the insert-receiving pocket of the clamp.
