Articulating surgical device
First Claim
1. A surgical device for performing surgery comprising:
- an elongate member having a straight section and an articulating section movable relative to the straight section; and
an articulation mechanism including;
an articulation lock; and
an articulation cable plate coupled with the articulating section of the elongate member, the articulation cable plate irreversibly transitionable from a first state in which the articulation cable plate is in a distal-most position to a second state in which the articulation cable plate is selectively engageable with the articulation lock to transition the articulation lock between a locked position, in which articulation of the articulating section of the elongate member is inhibited and, an unlocked position, in which the articulating section of the elongate member is articulatable.

Abstract
An articulation mechanism for a surgical instrument includes an articulation assembly, a plurality of cables, and a trigger. The cables are coupled to the articulation assembly at a proximal end thereof and extend distally therefrom. The cables are configured to engage an end effector assembly of the surgical instrument at a distal end thereof. The trigger is coupled to the articulation assembly and is selectively moveable from a shipping position to a use position. In the shipping position, the cables are substantially un-tensioned. In the use position, the cables are disposed in an initial tensioned position. In the use position, the trigger is moveable between an unlocked position and a locked position. In the unlocked position, the cables are selectively tensionable to articulate the end effector assembly. In the locked position, the tensions on the cables are maintained to lock the end effector assembly in position.

10. A surgical device for performing surgery comprising:
-
an elongate member having a straight section and an articulating section configured to articulate with respect to the straight section; an articulation mechanism including; an articulation cable plate movable to effect articulation of the articulating section of the elongate member, the articulation cable plate irreversibly transitionable from a first state in which the articulation cable plate is in a distal-most position to a second state; and an articulation lock selectively engageable with the articulation cable plate, the articulation cable plate in the second state transitionable between a first position, in which the articulation cable plate engages the articulation lock, which, in turn, locks a relative position of the articulating section relative to the straight section, and a second position in which the articulation cable plate is disengaged from the articulation lock to enable articulation of the articulating section relative to the straight section; and an end effector 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
