Abstract:
1. A medical device for treating a hard tissue, comprising: a handle having an actuating portion mechanically coupled to a working end of a shaft; the shaft comprising a first sleeve located concentrically within a second sleeve where the first sleeve and second sleeve are attached at a distal portion of the shaft where the first sleeve and second sleeve each comprises a series of slots or notches to permit deflection of the working end into an articulated configuration, where the series of slots or notches in the first sleeve is radially offset from the series of slots or notches in the second sleeve; wherein movement of the actuating portion results in relative movement between the first and second sleeves to move reversibly between a linear configuration and the articulated configuration, where the radially offset series of slots or notches in the first and second sleeves limits movement between the linear configuration and articulated configuration to a single plane; and a sharp tip located at a distal tip of the working end, the sharp tip adapted to penetrate hard tissue and a point of the sharp tip is offset to engage hard tissue when advanced therein to assist in deflecting the working end.
