Patent ID: 8808300

Claim:
An assembly, comprising: a guide component including: a base defining a distal bone contacting surface and an opposite proximal surface and having (i) a coupling structure including a passageway sidewall that defines a first passageway and a first coupling component, said passageway sidewall defining a lateral passageway opening, and (ii) a finger extending from said first coupling structure, said finger defining a slot having a slot sidewall that defines a lateral slot opening that is common with respect to said lateral passageway opening so that said slot communicates with said first passageway through said passageway sidewall and said slot sidewall, and said coupling structure and said finger collectively defining said distal bone contacting surface of said base, and a handle extending from said base; and a sheath having (i) a proximal sheath end portion defining a proximal sheath opening, and (ii) a distal sheath end portion defining a distal sheath opening, said sheath defining a second passageway extending between said proximal sheath opening and said distal sheath opening, and said distal sheath end portion including a second coupling component configured to cooperate with said first coupling component to couple said sheath to said base, wherein said first passageway is aligned with said second passageway when said sheath is coupled to said base; a stop structure extending through said proximal sheath opening and defining a central passage, said stop structure including an external surface having a plurality of keyways defined therein, wherein said proximal sheath end portion includes a key member configured to be selectively received in any one of said plurality of keyways, and wherein said stop structure is fixed in relation to said sheath when said key member is positioned in any one of said plurality of keyways.
