Patent ID: 7160109

Claim:
A fixture mount for disposition between the adjacent end of a rotatable member and the adjacent end of an aligned implant and for transmitting there between torque of a magnitude less than a damaging torque that would cause damage to the implant, said fixture mount comprising: an elongate body having a first end portion for engaging the adjacent end of the rotatable member and a second end portion for engaging the adjacent end of the implant; a first mating element on said body for releasably engaging one of the adjacent ends, said first mating element adapted to engage said one end and transmit torque applied by the rotatable member when the applied torque is less than a first predetermined value, and adapted to disengage from said one end and cease to transmit torque when the applied torque exceeds said first predetermined value, said first predetermined value being less than the implant-damaging torque; and a second mating element on said body for releasably engaging the other one of said adjacent ends, said second mating element adapted to engage said other adjacent end and transmit torque applied by the rotatable member when the applied torque is less than a second predetermined value, and adapted to disengage from said other adjacent end and cease to transmit torque when the applied torque exceeds said second predetermined value, said second predetermined value being higher than said first predetermined value and less than the implant-damaging torque; wherein said first mating element comprises a socket having an array of recesses, and wherein said socket deforms to the extent that it disengages from said one end and ceases to transmit torque when said first predetermined value is applied.
