An articulating surgical instrument which has an articulation transmission assembly for remotely articulating an end effector of the instrument is disclosed. The articulation transmission assembly includes a detent housing mounted on the instrument with a plurality of detent teeth. A compressible deck with a plurality of ratchet deck teeth is matingly coupled with the teeth of the detent housing when the assembly is in a first locked position. An actuator is fitted on the detent housing for applying a rotational force on the deck. A drive member is in communication with the deck for translating rotational movement of the deck into axial movement of an elongated transmission member which is attached to the drive member. When a rotational force is applied to the actuator, the deck compresses to decouple the teeth of the deck from the teeth in the detent housing. The decoupling of the teeth reduces the rotational force necessary to rotate the deck and consequently the drive member which moves the elongated transmission member axially to effect articulation. Consequently, the ratcheting rotation of the deck from the first locked position to a second locked position, and therefore the articulation of the end effector from a first position to a second position angled from the first position, is significantly facilitated.

[ What is claimed is:] [7.] An articulating surgical instrument comprising an articulation transmission assembly for remotely articulating an end effector of said instrument, said articulation transmission assembly including:a) a detent housing mounted on said instrument, said detent housing having a plurality of detent teeth thereon;b) a compressible deck with a plurality of ratchet deck teeth thereon, said deck teeth matingly coupled with said detent teeth when said articulation transmission assembly is in a first locked position;c) an actuator fitted on said detent housing for applying a rotational force on said deck, wherein when said rotational force is applied, said deck compresses so as to decouple said deck teeth from said detent teeth for facilitating ratcheting rotation of said deck from said first locked position to a second locked position; andd) a drive member in communication with said deck for translating rotational movement of said deck into axial movement of an elongated transmission member attached to said drive member.
