Patent ID: 8439920

Claim:
An adapter for surgical reamer driver comprising: a molded unitary piece made from surgically compatible flexible material having a central axis and consisting essentially of: a base having an upper surface and an opposing lower surface, Two opposing continuous side walls projecting from the upper surface of the base in a first direction, a recess formed between said opposing continuous side walls, said recess comprises a central circular portion coaxial with the central axis of the unitary piece and a pair of rectangular recesses aligned with one another and extending radially outwardly from the central circular portion, wherein said recess is sized and shaped to match with a configuration of a crossbridge reamer; a plurality of resilient hook elements projecting in said first direction from the upper surface of said base and located at an opposite ends of said base, said plurality of resilient hook elements comprises a pair of opposing resilient hook elements being in line with the radially extending rectangular recesses and spaced radially outward from said recess, each of said resilient hook elements has an L-shape which comprises a portion that extends in said first direction from the upper surface of the base and terminates in a lip that extends in a direction substantially parallel to the upper surface of the base and substantially perpendicular to said portion that extends in the first direction and having a portion with an upper angled surface, wherein the lips of the opposing resilient hook elements extends inwardly towards one another for capturing the crossbridge reamer, such that when inserting the crossbridge reamer axially into the recess, the upper angled surface of the lip allows camming of the opposing lips outwardly by virtue of the yieldability of the hook elements to deflect sufficiently to permit entry of a rectangular bar of the crossbridge reamer and permit the lips to come back into place to hold the reamer; and a central cylindrical element extending in a second direction from the opposing lower surface of the base and being coaxial with said central axis and terminating in an interface, said interface comprises a plurality of circular rods extending radially outward from the central cylindrical element and being placed perpendicularly from one another forming a crossbar interface configured to connect with a reamer driver that accepts crossbar style reamers, Wherein said adapter enables rapid and immediate connection and disconnection in only axial direction.
