Abstract
A surgical chisel is formed by a flexurally rigid chisel shank and a thin, elongated chisel blade fixed at its front end, which are both displaceably guided in slideways in a chisel guide, which lends the chisel blade buckling resistance.
Claims5

- a chisel shank (3) having a first end adapted to receive the impact of a hammer;
- an elongated chisel blade (2) coupled at a first end to a second end of said chisel shank and having a cutting edge at a second end;
