Locking articulation mechanism
First Claim
1. A surgical device comprising:
- a handle assembly;
an elongated body extending from the handle assembly; and
an articulation mechanism operably connected to the handle assembly and configured to selectively articulate and lock an articulatable tool assembly in one or more positions, the articulation mechanism including;
a main shaft member mounted for rotation and connected to an articulation linkage;
a locking member configured to be received about the main shaft member and rotationally fixed relative to the elongated body, the locking member defining a plurality of notches;
an articulation handle fixedly secured to the main shaft member and configured for rotation relative to the locking member; and
a lug member mounted on the articulation handle being configured to rotate with the articulation handle, at least a portion of the lug member being mounted for being selectively received within a notch of the plurality of notches when in a first position, and for being disposed radially outward of the plurality of notches when in a second position, the lug being inwardly biased toward the first position.

Abstract
A surgical device including a handle assembly, an elongated body extending from the handle assembly, and an articulation mechanism connected to the handle assembly and configured to selectively articulate and lock an articulable tool assembly in one or more positions is provided. The articulation mechanism includes a main shaft member mounted for rotation and connected to an articulation linkage, a locking member configured to be received about the shaft portion of the main shaft member, the locking member defining a plurality of notches, an articulation handle fixedly secured to shaft portion of the main shaft member and configured for rotation relative to the locking member, and a lug member operatively mounted on the articulation handle and including a locking tab configured to be selectively received within a notch of the plurality of notches formed in the locking member.
