1. An arthroscopic surgical device comprising:
a body with a proximal end, a distal end, and a body longitudinal axis extending between said proximal end and said distal end, said body comprising:
an elongated sheath arranged along a sheath longitudinal axis, said sheath comprising:
a sheath flexible portion having a single articulatable joint;
an elongated spine arranged along a spine longitudinal axis, said spine connected to said sheath, said spine comprising a single spine joint;
wherein said spine is rigid in a direction of elongation of said spine;
wherein said sheath longitudinal axis and said spine longitudinal axis are aligned, for at least a portion of a sheath longitudinal length,
wherein said single articulatable joint of said flexible portion axially overlaps with said single spine joint, bending said single spine joint thereby bending said single articulatable joint of said flexible portion;
wherein said spine comprises:
a first elongated spine rod;
a second elongated spine rod;
a distal portion of the spine, where said distal portion:
is attached to a distal end of said first spine rod at a first point on said distal portion; and
is attached to said second spine rod at a second point on said distal portion, spaced from said first point;
wherein axial movement of said first spine rod in a distal direction changes an angle of said distal portion with respect to long axes of said first and said second spine rod.
