The insert also includes a channel having an opening at the tip for the passage of fluid.

Abstract: A surgical device (1) for bone surgery including a body (2) able to be gripped by the user and a tip (3) mounted at the head of the body and set in vibration at a modulated ultrasonic frequency to operate on bone tissue, the surgical device (1) being particularly suitable for oral surgical procedures such as bone sampling, excision of cysts, third molar extraction, preparation of alveolar sites, creation of an opening into the maxillary sinus (Caldwell Luc), elevation of the maxillary sinus by the crestal route and orthopedic and neurosurgical procedures such as osteoplasty, ostectomy and osteotomy.

Abstract: A handpiece (1) is described for making holes in bone tissue including a surgical tool (3; 103) provided with a tip or head (40; 140) able to make a hole in the bone. The handpiece works by ultrasound, the tip (40; 140) of the tool includes a plurality of cutting elements (43) defining the profile of the hole to be made in the bone, and in the body of the tool there is provided a main channel (36) which ends in an outlet hole (44) opening in the tip of the tool (40; 140) for the passage of a cooling fluid, so as to cool the work area affected by the tool tip.

Abstract: An ultrasound resonant dipole or sonotrode (3) for medical applications includes: a tang (30, 31, 32) designed to be connected to a handset including an utrasound transducer (1) that vibrates at ultrasound frequency with a longitudinal axis of vibration (X-X) coaxial with the axis of the tang, an annular element (33) connected to the tang, and a tool (5) disposed on the annular element (33) connected to the tang, and a tool (5) disposed on the annular element (33) with an axis of vibration (Y-Y) inclined with respect to the axis of vibration (X-X) of the transducer. The annular element (33) is discontinuous and has an aperture (34).

Abstract: An implant site preparation method comprising the following steps: lifting of the muco-periosteal flaps (9, 10) of the operating area, so as to expose an area of bone (11) in which the procedure is to be performed; application of a tip (35) of an insert (3) of an ultrasound handpiece (1) to said involved area of bone (11); vibration of said tip (35) at ultrasound frequency and simultaneous irrigation of said involved area of bone (11) with cooling fluid through a channel which passes through said insert and opens in the tip of said insert; and application with the hand on the handpiece of a light pressure combined with an angular oscillating movement, so that the tip (35) of the insert presses on the bone cortex (11), in the area chosen for the implant site, until a hole (12) is obtained of a suitable depth for the length of the chosen implant.

Abstract: An optical system for the polymerization of photosetting compounds or resins is described. The optical system includes a LED mounted on a heat dissipater inside the body of a dental handpiece and an optical fibre or light guide mounted at the top of the handpiece to convey and emit at, its output end, the light emitted by the LED so as to direct it onto the area in which the photosetting compound or resin is to be polymerized. The system also includes an optical element or optical conveyor able to couple the LED with the optical fibre to convey the light beam emitted by the LED toward the input of the optical fibre, said optical element being of such a shape as to minimize dispersion of the light beam emitted by the LED thereby acting as a light beam concentrator.

Abstract: A dental handpiece for the polymerization of photosetting resins or compounds comprising as its polymerizing light source, at least one LED incorporated in the handpiece, the electrical supply signal for the LED light source being drawn from connectors of other types of hand pieces and being processed by means of an appropriate electronic circuit in order to make the electrical supply signal suitable for bias of said LED light source.
