Patent ID: 7819876

Claim:
An orthopaedic pin driver for impacting bone at a surgical site, the pin driver comprising: a housing having a proximal end, a distal end, and a longitudinal axis therebetween; an array of pins mounted in the housing for reciprocating motion parallel to the longitudinal axis between a first longitudinal position and a second longitudinal position, each pin having a proximal end and a distal end, the proximal end of each pin forming a sharpened tip projecting from the housing by a projection distance at least when each pin is in the second longitudinal position, the array of pins arranged in a two-dimensional pattern to be reproduced on a surface of the bone by an impacting action of the pins; a drive mechanism engaging the pins to reciprocate the pins between the first and second positions, the drive mechanism selectively driving individual pins of the array of pins in response to a control signal, the array of pins arranged in an array of columns and rows, the drive mechanism being able to selectively drive individual pins in the array to produce a variety of user selectable patterns; and a limiting means for individually limiting travel of the pins reciprocating between the first and second positions and for individually varying a maximum projection distance of each pin.
