摘要： The present invention relates to a cutting device (1) for surgical or dental use, comprising a motor (10) connected to a handpiece (4) provided with a transmission module (2) for a cutting tool (3), the transmission module (2) comprising:
a motor coupling part arranged to be set in rotation by the said motor (10);
a kinematic chain transforming the rotary movement of the motor (10) into a first linear reciprocating movement (M1) of a blade holder (27) via a rotary transmission shaft (22) provided with an eccentric (23),
the transmission module (2) being characterized in that it further comprises a counter-mass (5) arranged so as to move according to a second linear reciprocating movement (M2) synchronized with the first linear reciprocating movement (M1) of the blade holder (27), and in the opposite direction to the latter.-

摘要： The present invention relates to a transmission rotor for a handpiece (1) suitable to dental or chirurgical applications, comprising a device for clamping a drilling tool (100), able to be actuated in rotation about an axis of rotation (R) by means of a drive mechanism which comprises a drive shaft (2) rotatable about the said axis of rotation (R).
The clamping device comprises a clamp (4) disposed inside the drive shaft (2) for axially securing the drilling tool (100) with respect to the axis of rotation (R), the clamp (4) co-operating with a plunger (5) for releasing the drilling tool (100), as well as a radial guide bush (3) of the drilling tool, rotating integrally with the drive shaft (2), and wherein it comprises a selective angular coupling mechanism (Cs) between the clamp (4) and the guide bush (3) or the drive shaft (2) directly, according to the chosen preferred embodiment; the selective angular coupling mechanism (Cs) exerting an angular holding torque (C) between the clamp (4) and the guide bush (3) or respectively the drive shaft (2), the value of which being inferior to that corresponding to the slip threshold between the said clamp (4) and the drilling tool (100).-

摘要： Compressed air handpiece including a handle connected to a head housing a turbine. The turbine includes a moving wheel from a periphery of which extends a plurality of blades which define an outer diameter of the moving wheel. The handpiece also includes injection means, whose function is to direct onto the blades of the moving wheel a compressed air flow whose pneumatic energy is converted into kinetic energy when the compressed air flow strikes the blades of the moving wheel. The injection means take the form of an independent insert inside which is arranged a compressed air flow feed pipe and which is mounted inside the handle of the handpiece.
