Abstract: A vibratory instrument includes a tool releasably mounted on a tool carrier designed to be coupled with a vibration generator device. The tool includes in succession along a longitudinal axis: a working portion presenting a free end for reproducing the vibration transmitted by the vibration generator device; a coupling portion; and an elastically-deformable attachment portion disposed upstream from the coupling portion. The tool carrier includes in succession along a longitudinal axis: a housing receiving the attachment portion of the tool; and a coupling bearing surrounding the coupling portion of the tool, at least in part. The attachment portion of the tool presents outside dimensions that are adapted relative to the inside dimensions of the housing of the tool carrier to prevent contact between the attachment portion and the housing when the coupling portion of the tool is in contact with the coupling bearing of the tool carrier.

Abstract: A surgical instrument including an operative assembly (1) and a supply assembly (3). The back of the operative assembly (1) and the front of the supply assembly (3) have complementary connectors forming a sealed connection between the assemblies. The supply assembly (3) comprises at least one duct (43) for feeding a first fluid as far as the connectors. The surgical instrument is characterized in that it comprises a member (31) for sealing the fluid duct (43) when the operative assembly (1) is connected to the supply assembly (3), and the operative assembly (1) includes a member (25) for feeding at least one second fluid.
