Abstract: A device for medical use and particularly for dental use, of which the main component is a rigid video-endoscope (10) supported by an articulated and compensated arm, comprises: a rigid video-endoscope (10) with CCD catcher (13), composed of a grip (11) which is extended into an optical tube (12) coaxial therewith, said optical tube (12) being made so to provide an image of the object examined on the plane of the CCD catcher (13), the imaging being directed in the extension of the axis (14) of the video-endoscope (10); a sleeve (32) which covers the optical tube (12) and which protects it from the risks of contamination during use, the sleeve (32) being coaxial with optical tube (12), freely rotatable on itself and lockable in the distal part of the grip (11) of the video-endoscope (10), between the sleeve (32) and the optical tube (12) an airspace being defined in which pressurized air is inserted; a compensated, articulated arm that bears, fixed to its distal end, a support on which the video-endoscope (

Abstract: A direct view rigid video-endoscope (11) supported by an articulated and compensated arm (2), equipped with a grip (3) crossed by an air flow (92) originating from a generator (93) upstream of the device. The air flow (92) comes out of small holes (8) made in the distal end (28) of the grip (3), at the base of an optical tube (10).

Abstract: A pneumatically operated, simplified valve actuating device for dental equipment, the valve being capable of avoiding an undesirable dripping of dental instruments at the end of the work. The device includes a valve actuating element identified in a four-way valve, whose body includes a housing for a piston connected to a bobbin, wherein said casing is on one side connected to a selector unit and on the other side to a one-way retention valve, capable of receiving pressurized air from a reducer unit and passing it from said selector unit to a constantly pressurized air line coming directly from said reducer unit and to at least one dental instrument.
