Abstract
An axial load limiting system can include a handle having a lever pivotably connected to the handle, a hollow shaft slidably attached to the handle, and a rod operably connected on the proximal end to the lever and movable axially inside the shaft. A surgical implement, for example, a curette, can be connected to the distal end of the rod and pivotably connected to the distal end of the shaft. The system can include a biasing mechanism adapted to be compressed within a cavity in the handle by an axial load in excess of a predetermined axial load. When pivoting of the surgical implement is restricted due to an obstruction, such as hard tissue, and the excessive axial load is placed on the rod, the rod and the surgical implement can move the shaft in the distal direction so as to compress the biasing mechanism, thereby relieving the rod and surgical implement of the excessive axial load.
