IMPROVED HANDSET FOR AN ULTRASONIC DEVICE

A handset (1) for an ultrasonic device for bone cement removal and/or osteotomy operations comprises a handset body (1') which encloses ultrasound generating means (2) including at least one piezoelectric transducer (2a) and a horn (2b), connection means (4f) configured to connect said handset (1) to a tool to which the ultrasounds generated by the ultrasound generating means (2) are transmitted, a duct (5) for circulation of a cooling medium, said duct (5) extending at least partially on the outside of the handset (1), a triggering element (10, 11, 14), activation of which causes the activation of the ultrasound generating means (2), and a control lever (8) coupled to the handset body (1') at a connection point (9), said control lever (8) being configured to activate the triggering element (10, 11, 14) by means of its movement about the connection point (9).
