A ronguer or the like is formed with a pistol-shaped main frame assembly having a hollow, tubular cutting element releasably clamped at the forward end of the barrel of the frame. A rod slidably received in the barrel projects beyond the front end of the cutting element and has a rearwardly facing shoulder which can be drawn into the cutting element to shear bone or other material engaged between the shoulder and sharpened forward edge of the cutting element. The rod member may be selectively located in any of four rotative orientations for up-cutting, down-cutting or side-cutting from either side. The device is readily disassembled for cleaning and sterilization.
