ABSTRACT:
In a medical instrument are provided cutting forceps for taking tissue samples, removing elongated body elements, such as nerve or vein portions, or the like. An inner tube (7) is inserted in an outer tube (9). One tube (7 or 9) is axially displaceable against the other tube (9 or 7). One of the tubes (7 or 9) has the cutting forceps (20), whose closing movement is dependent on the other tube (9 or 7), the cutting forceps (20) comprising two cutting blades (21, 22), which have cutting edges (23) and common pivots (25) with a tube (7 or 9). The in each case other tube (7 or 9) has depressions (26) in the terminal edge (27), in which the pivots (25) are inserted during the closing of cutting forceps (20). The contours of depressions (26) are adapted to the outer contours of the cutting blades (21, 22).
