Articulating surgical device

A surgical device for performing surgery, comprising:

• a handle assembly including a cup portion;
• an elongate member extending from the handle assembly, the elongate member having an articulating section and a substantially stiff section, wherein the articulating section is configured to articulate with respect to the substantially stiff section;
• an articulation mechanism operatively associated with the handle assembly and the articulating section, wherein moving the handle assembly in a first direction relative to the substantially stiff section causes the articulating section to articulate towards the first direction relative to the substantially stiff section, the articulation mechanism including:
• an articulation cable plate disposed at least partially within the cup portion, the articulation cable plate coupled with the articulating section of the elongate member;
• and
• an articulation lock ring disposed within the cup portion of the handle assembly, the articulation lock ring having a plurality of circumferentially arranged fingers, the articulation cable plate movable between a locked position in which the plurality of fingers engage an inner surface of the cup portion to lock position of the handle assembly with respect to the elongate member and an unlocked position in which the plurality of fingers disengage from the inner surface of the cup portion, whereby the handle assembly is movable with respect to the elongate member;
• an end effector operatively coupled to the articulating section of the elongate member, the end effector having first and second jaw members, wherein the first and second jaw members are configured to move relative to each other between an open position and an approximated position;
• and
• a locking mechanism configured for fixing a relative position of first and second jaw members, the locking mechanism including a first ratchet assembly and a second ratchet assembly positioned within the handle assembly, the first and second ratchet assemblies being moveable relative to each other between an engaged position to lock the relative position of the first and second jaw members and a disengaged position to unlock the relative position of the first and second jaw members.

A surgical device for performing surgery, comprising:

• a handle assembly including a cup portion;
• an elongate member extending from the handle assembly, the elongate member having an articulating section and a substantially straight section, the articulating section configured to articulate with respect to the substantially straight section;
• an articulation mechanism operatively associated with the handle assembly and the articulating section, the articulation mechanism including:
• an articulation cable plate movable at least partially within the cup portion and operable to effect articulation of the articulating section of the elongate member;
• and
• an articulation lock ring operable with the articulation cable plate, the articulation cable plate selectively movable to engage the articulation lock ring which, in turn, causes the articulation lock ring to engage the cup portion to maintain a relative position of the articulating section with respect to the substantially straight section;
• an end effector operably coupled to the articulating section of the elongate member, the end effector having first and second jaw members movable relative to each other between an open position and an approximated position;
• and
• a locking mechanism configured for fixing a relative position of the first and second jaw members.
