摘要： A pin shear for shaping and cutting bone pins and other elongate elements to the desired length is described. A pneumatically operated, coaxial cutter assembly includes a cutter plug having pin passageways therethrough positioned inside a cutter body having an aperture therein located in registry with the passageway in a first position. The cutter plug is adapted to move within the cutter body to a second position out of registry with the aperture, whereby an elongate element positioned in the passageway and aperture is severed. A pneumatic operator including means for multiplication of the force applied is described.
