摘要： The invention relates to a hand-held instrument, for dental or surgical use, intended to rotate a rectilinear detachable tool (13). It comprises: a tubular sheath (1); a hollow shaft (3) rotatably mounted inside the sheath and consisting of an upstream portion (5) and a downstream portion (6) which in turn comprises an upstream portion (11) partially clamped around the upstream portion (5) of the shaft and a downstream portion (12) of which the inside diameter substantially matches the outside diameter of the tool (13); a clamp (14) rigidly rotationally connected to the shaft (3) but movable along the axis thereof, which clamp is placed inside and concentric with the upstream portion (5) of the shaft; and means for moving the clamp (14) longitudinally so that the jaws (17) thereof penetrate under the upstream portion (5) of the shaft (3) thereby gripping the tool.
