1. A surgical instrument, comprising:
(a) an instrument body;
(b) a guide shaft distally projecting from the instrument body along a central axis, including:
(i) a guide sidewall surrounding the central axis,
(ii) a guide lumen defined by the guide sidewall, and
(iii) a clearance opening radially extending through the guide sidewall in communication with the guide lumen;
(c) a first surgical tool, including:
(i) an elongate body at least partially positioned within the guide lumen, and
(ii) a distal head extending from the elongate body proximate to the clearance opening, the distal head being configured to deflect relative to the elongate body from a first position to a second position; and
(d) a second surgical tool slidably positioned within the guide lumen, the second surgical tool including:
(i) an enlarged portion, and
(ii) a narrowed portion,
the distal head, in the first position, being positioned within the guide lumen along the central axis,
the distal head, in the second position, being deflected from the central axis such that the distal head is obliquely oriented relative to the central axis, the distal head, in the second position, extending at least partially through the clearance opening thereby vacating at least a portion of the guide lumen for introducing the second surgical tool through the guide lumen, and
the enlarged portion of the second surgical tool being configured to urge the distal head of the first surgical tool toward the second position upon longitudinal alignment between the enlarged portion of the second surgical tool and the distal head of the first surgical tool.
