An inner guide assembly and surgical instrument including the same wherein the inner guide assembly includes a proximal tube guide defining first and second proximal channels extending longitudinally therealong, a distal tube guide defining first and second distal channels extending longitudinally therealong and disposed in alignment with the first and second proximal channels, respectively, and a wire clip disposed between the proximal and distal tube guides and defining a central channel having a first portion and a second portion. The first proximal channel, the first distal channel, and the first portion of the central channel are configured to cooperate to receive a first elongated component of a surgical instrument longitudinally therethrough. The second proximal channel, the second distal channel, and the second portion of the central channel are configured to cooperate to receive first and second lead wires of the surgical instrument longitudinally therethrough.
