A mechanism for connecting an orthopedic cutting tool to a driver, the mechanism comprising: a) a collar comprising an annular sidewall defining a collar throughbore that extends along a longitudinal axis A-A from a collar proximal portion having a collar proximal end to a collar distal portion having a collar distal end, the annular sidewall having a sidewall thickness spaced between an interior sidewall surface and an exterior sidewall surface, wherein at least two spaced apart first slots extend through the annular sidewall thickness from the sidewall distal end part way to the sidewall proximal end; b) a shank having a shank proximal portion with a shank proximal end that extends along the longitudinal axis A-A to a shank distal portion having a shank distal end, a cavity residing within the shank proximal portion and an annular sidewall that extends from the shank proximal portion to the shank distal end, the shank annular sidewall having a sidewall thickness that extends perpendicular to the longitudinal axis A-A, wherein at least two spaced apart second slots extend through the thickness of the shank annular sidewall from the distal end part way to the sidewall proximal end, and wherein the shank is disposed within the collar throughbore so that the collar is slidable in an axial direction along the longitudinal axis A-A with respect to the shank, the respective proximal and distal portions (106, 110) of the shank and collar oriented in parallel to the longitudinal axis A-A; c) a pin having opposed first and second pin ends disposed within the shank cavity, wherein the first and second pin ends extend through opposing third slots that extend through a thickness of the shank proximal portion perpendicular to the longitudinal axis A-A, and wherein the respective first and second pin ends are connected to the collar annular sidewall 20); and d) a bias member disposed within the shank cavity proximal of the pin, wherein the bias member provides a bias force in a distal direction against the pin. a) a collar comprising an annular sidewall defining a collar throughbore that extends along a longitudinal axis A-A from a collar proximal portion having a collar proximal end to a collar distal portion having a collar distal end, the annular sidewall having a sidewall thickness spaced between an interior sidewall surface and an exterior sidewall surface, wherein at least two spaced apart first slots extend through the annular sidewall thickness from the sidewall distal end part way to the sidewall proximal end; b) a shank having a shank proximal portion with a shank proximal end that extends along the longitudinal axis A-A to a shank distal portion having a shank distal end, a cavity residing within the shank proximal portion and an annular sidewall that extends from the shank proximal portion to the shank distal end, the shank annular sidewall having a sidewall thickness that extends perpendicular to the longitudinal axis A-A, wherein at least two spaced apart second slots extend through the thickness of the shank annular sidewall from the distal end part way to the sidewall proximal end, and wherein the shank is disposed within the collar throughbore so that the collar is slidable in an axial direction along the longitudinal axis A-A with respect to the shank, the respective proximal and distal portions (106, 110) of the shank and collar oriented in parallel to the longitudinal axis A-A; c) a pin having opposed first and second pin ends disposed within the shank cavity, wherein the first and second pin ends extend through opposing third slots that extend through a thickness of the shank proximal portion perpendicular to the longitudinal axis A-A, and wherein the respective first and second pin ends are connected to the collar annular sidewall 20); and d) a bias member disposed within the shank cavity proximal of the pin, wherein the bias member provides a bias force in a distal direction against the pin.
