Abstract: The invention relates to dental method and to a device for separating different materials to be removed during dental treatment conducted at the boundary of healthy bone tissue or, optionally, to abrade the healthy bone tissue. According to the invention, a highly-pressurized liquid provided in the form of a concentrated free liquid jet spray is directed with a large amount of kinetic energy onto the tooth surface to be treated via a nozzle mounted on the end of a dental tool. The working element of the hand tool (5) is formed by a nozzle (6) which is suited for discharging a concentrated highly-pressurized liquid jet spray and which is supplied with liquid by a hydraulic supply unit (2). Said hydraulic supply unit serves as an energy source and is controlled by an adjustable pressure controller (28). In addition, the hydraulic supply unit (2) contains a hydraulic pump (17) which is actuated by a drive unit and which is connected to a liquid container (3). A pneumatically controlled three-way valve (37) is placed in the supply line of said pump (17) which leads to the nozzle (6). A tool sensing element valve (39), said tool sensing element valve being actuated by a switching element that detects the lifting of the hand tool (5), as well as a foot valve (40) which is actuated by a foot switch are connected in series in the pneumatic control circuit of said three-way valve.

Abstract: Device with a miniaturized photoionic head for the treatment of a material. The device comprises at least one optical fibre (2), a pulsating light source for treating the material (10); means for injecting said light into an end of the fibre, and a miniaturized photoionic head (8) comprising a collar (16), with a side being integral with a fibre end while the other side of the ring is placed against the material. The collar confines a plasma formed, by means of the pulsating light, in the space delimited by said ring, from the material or matter (20) placed in said space, for the treatment of the material. Application in the surface treatment of metals.

Abstract: Die Erfindung betrifft ein Technikhandstück mit einer länglichen Griffhülse, in der eine von einem Antriebsmotor antreibbare Welle gelagert und eine Spannvorrichtung für ein von der Welle anzutreibendes Werkzeug angeordnet ist.
Zur Erzielung einer griffgünstigen Handstückform, die ein weitgehend ermüdungsfreies Arbeiten mit dem Handstück erlaubt, ist die Griffhülse (1) in ihrer Außenkontur im Querschnitt ellipsenförmig ausgebildet, wobei das Verhältnis der beiden Ellipsenachsen (a, b) im mittleren Bereich der Griffhülse (Fig. 5) ungleich ist und gegen das werkzeug- und das antriebsseitige Ende hin gleich wird, so daß an den Enden (5, 6) ein kreisförmiger Querschnitt vorhanden ist. Die kleinere Ellipsenachse (Nebenachse b) weist im Griffbereich, vorzugsweise vom antriebsseitigen Ende (5) aus bis auf etwa 2/3 der Gesamtlänge (1) der Griffhülse, ein konstantes Maß auf; dagegen wird die größere Ellipsenachse (Hauptachse a) vom mittleren Bereich der Griffhülse (Fig. 5) aus nach beiden Enden (5, 6) hin kleiner. Das Handstück ist insbesondere für zahnärztliche Technikarbeiten vorgesehen.

Abstract: A surgical tool assembly for forming holes in bone at precise locations and to controlled depths. The drilling tool has a leading apical tip and a shank. The shank includes an annular groove at a predetermined distance from the apical tip. An adjustable stop gauge is coupled to the shank. The stop gauge includes an indexing adapter which telescopically supports a tubular collar. The collar includes an integrated impeller that accentuates irrigation of the treatment site during surgical procedures. The adjustable stop gauge may be used in combination with a guided surgery jig. The jig includes a guide bushing having a generally semi-cylindrical alignment valley adapted to receive the spinning collar of the stop gauge. The alignment valley includes an elevated internal abutment step having a semi-annular surface adapted to engage the collar when the apical tip reaches a predetermined penetration depth in the bone.
