A medical device, for treating hard tissue, comprising: a handle having a shaft with a tip affixed thereto; the handle having an actuating portion and being configured to receive and transfer an impact force applied thereto; the shaft comprising a first sleeve located concentrically within a second sleeve, the shaft having a distal portion comprising a working end capable of moving between a linear configuration and an articulated configuration and wherein each sleeve comprises a series of slots or notches to limit deflection of the articulating portion wherein the respective series of slots or notches are radially offset in adjacent sleeves, wherein the first sleeve is affixed via a mechanical fixation means to the second sleeve at a working end such that, upon actuation of the actuation portion, proximal movement of the first sleeve causes the working end to assume the articulated configuration, wherein the linear configuration and the articulated configuration are limited to a single plane, wherein the shaft is configured to transfer the impact force to the tip, wherein the tip is coupled to the first and second sleeves of the shaft by a resilient member such that it is flexible relative to the working end of the shaft and is configured to penetrate hard tissue upon the application of the impact force, the tip comprising a beveled surface and an offset distal point being offset towards a direction of curvature of the articulated configuration, wherein the offset distal point drives the tip and working end towards the direction of curvature upon the application of the impact force when advancing through hard tissue, and wherein articulation of the working end is driven by a combination of actuation of the actuation portion and forces acting on the beveled surface as the tip is advanced into tissue. a handle having a shaft with a tip affixed thereto; the handle having an actuating portion and being configured to receive and transfer an impact force applied thereto; the shaft comprising a first sleeve located concentrically within a second sleeve, the shaft having a distal portion comprising a working end capable of moving between a linear configuration and an articulated configuration and wherein each sleeve comprises a series of slots or notches to limit deflection of the articulating portion wherein the respective series of slots or notches are radially offset in adjacent sleeves, wherein the first sleeve is affixed via a mechanical fixation means to the second sleeve at a working end such that, upon actuation of the actuation portion, proximal movement of the first sleeve causes the working end to assume the articulated configuration, wherein the linear configuration and the articulated configuration are limited to a single plane, wherein the shaft is configured to transfer the impact force to the tip, wherein the tip is coupled to the first and second sleeves of the shaft by a resilient member such that it is flexible relative to the working end of the shaft and is configured to penetrate hard tissue upon the application of the impact force, the tip comprising a beveled surface and an offset distal point being offset towards a direction of curvature of the articulated configuration, wherein the offset distal point drives the tip and working end towards the direction of curvature upon the application of the impact force when advancing through hard tissue, and wherein articulation of the working end is driven by a combination of actuation of the actuation portion and forces acting on the beveled surface as the tip is advanced into tissue.
