1. A Rongeur comprising:
a top shaft, having a proximal end and a distal end, the top shaft proximal end having a cutting edge, and the top shaft distal end defining a cavity; the top shaft slidably connected to a fixed bottom shaft having a proximal end and a distal end, the bottom shaft proximal end having a foot plate, and the bottom shaft distal end defining a slot and transitioning into a fixed rear handle; a front handle having a distal end and a proximal end, the front handle distal end defining a handle pivotally connected to the fixed bottom shaft, and the front handle proximal end fitted through the slot and into the cavity; the front handle proximal end and the to shaft distal end comprising a drive pin and drive hole assembly, the drive pin received in the drive hole; a push button actuator operably connected to the fixed bottom shaft and in contact with a rear surface of the front handle proximal end, the push button actuator having an outer circumference and a groove; wherein in a normal position the front handle rear surface contacts the push button actuator outer circumference, thereby limiting the retraction of the top shaft; and upon depression of the push button actuator to an activated positon, the front handle rear surface contacts the push button actuator groove, thereby allowing the top shaft to retract, separate from the fixed bottom shaft, and hinge open at the drive pin and drive hole assembly to at least an acute angle, exposing the Rongeur for thorough cleaning and sterilization. |
