A surgical device, comprising: a housing; an elongate shaft extending distally from the housing; an articulation joint coupled to a distal end of the elongate shaft, the articulation joint comprising: an outer sleeve having a plurality of radially-extending slots formed therein; and an inner guide disposed within the outer sleeve, wherein each of the outer sleeve and the inner guide is coupled to the elongate shaft, and the combination thereof forming at least three separate channels that each extend a length of the inner guide, the three separate channels including a first channel configured to receive an actuation member that extends from the housing, through the elongate shaft, and into the articulation joint, a second channel configured to receive a first articulation arm that extends from the housing, through the elongate shaft, and into the articulation joint, and a third channel configured to receive a second articulation arm that extends from the housing, through the elongate shaft, and into the articulation joint; and an end effector coupled to the articulation joint and configured to be actuated by the actuation member and articulated by the first and second articulation arms, characterized in that the outer sleeve further comprises: a tubular body having a proximal portion, an intermediate portion, and a distal portion, with the intermediate portion having opposed support arms that extend between the proximal and distal portions; a first cage member in which a portion of the plurality of radially-extending slots are formed, the first cage member engaging the opposed support arms and being coupled to the inner guide; and a second cage member in which another portion of the plurality of radially-extending slots are formed, the second cage member engaging the opposed support arms, being disposed on an opposite side of the opposed support arms than the first cage member, and being coupled to the inner guide. a housing; an elongate shaft extending distally from the housing; an articulation joint coupled to a distal end of the elongate shaft, the articulation joint comprising: an outer sleeve having a plurality of radially-extending slots formed therein; and an inner guide disposed within the outer sleeve, wherein each of the outer sleeve and the inner guide is coupled to the elongate shaft, and the combination thereof forming at least three separate channels that each extend a length of the inner guide, the three separate channels including a first channel configured to receive an actuation member that extends from the housing, through the elongate shaft, and into the articulation joint, a second channel configured to receive a first articulation arm that extends from the housing, through the elongate shaft, and into the articulation joint, and a third channel configured to receive a second articulation arm that extends from the housing, through the elongate shaft, and into the articulation joint; and an outer sleeve having a plurality of radially-extending slots formed therein; and an inner guide disposed within the outer sleeve, wherein each of the outer sleeve and the inner guide is coupled to the elongate shaft, and the combination thereof forming at least three separate channels that each extend a length of the inner guide, the three separate channels including a first channel configured to receive an actuation member that extends from the housing, through the elongate shaft, and into the articulation joint, a second channel configured to receive a first articulation arm that extends from the housing, through the elongate shaft, and into the articulation joint, and a third channel configured to receive a second articulation arm that extends from the housing, through the elongate shaft, and into the articulation joint; and an end effector coupled to the articulation joint and configured to be actuated by the actuation member and articulated by the first and second articulation arms, characterized in that the outer sleeve further comprises: a tubular body having a proximal portion, an intermediate portion, and a distal portion, with the intermediate portion having opposed support arms that extend between the proximal and distal portions; a first cage member in which a portion of the plurality of radially-extending slots are formed, the first cage member engaging the opposed support arms and being coupled to the inner guide; and a second cage member in which another portion of the plurality of radially-extending slots are formed, the second cage member engaging the opposed support arms, being disposed on an opposite side of the opposed support arms than the first cage member, and being coupled to the inner guide. a tubular body having a proximal portion, an intermediate portion, and a distal portion, with the intermediate portion having opposed support arms that extend between the proximal and distal portions; a first cage member in which a portion of the plurality of radially-extending slots are formed, the first cage member engaging the opposed support arms and being coupled to the inner guide; and a second cage member in which another portion of the plurality of radially-extending slots are formed, the second cage member engaging the opposed support arms, being disposed on an opposite side of the opposed support arms than the first cage member, and being coupled to the inner guide.
