A medical dental grinding apparatus comprises an apparatus body, wherein an air pipeline, a clamping mechanism, and a grinding mechanism are provided in the apparatus body; the air pipeline includes an air inlet pipeline, an air outlet pipeline, and a U-shaped connection pipeline; a silencer is connected to an upper port of the air outlet pipeline; a plane where the air pipeline is located is perpendicular to a plane where the clamping mechanism is located, and the grinding mechanism is provided below the air pipeline; the grinding mechanism is driven by high-pressure air in the air pipeline to operate, so that a hidden danger of electric leakage caused by using an electric apparatus in a fragile oral environment is avoided; and a steel wire is fixed by the clamping mechanism, so that the grinding safety is ensured.

A dual-ended triple tooled dental applicator apparatus, comprising a plurality of tools with interchangeable dental tool applicators. The dental apparatus further comprises an elongated handle having two distinct tools on both ends and being detachable and interchangeable. During procedures, the dentist can alternate between both ends of the apparatus and among three dental tool applicators. A set of overlapping and circumferential friction enhancement means, along and about the apparatus, facilitate safe and effective handling during procedures. The multi-functioned dental apparatus is comprised of a lightweight but rigid materials (e.g., plastic), which allows the dentist to efficiently use the same tool for working with and applying different materials to a patient's teeth. Upon completion of a given procedure, the entire device may be readily disposable.

A surgical torque-transferring instrument includes a preferably universal handpiece to which a handpiece shaft having an internal torsion rod or an internal tool shaft can be connected. The torsion rod can be connected to a torque transmission train or drive within the handpiece via a plug-type coupling which includes a male and female coupling piece which can be axially plugged into each other. The cross-sectional shape of the two coupling pieces approximately corresponds to a four-leaved cloverleaf.

The invention relates to a handpiece (100) for a medical or cosmetic processing device, having:a connection line (102) at a connection end (101); anda housing (104) in which a receiving area is provided between the connection end (101) and the processing end (103), a rotary drive unit being receivable in said receiving area in order to drive a rotary tool (210) which can be attached to the processing end (103). The invention is characterized in that the handpiece (100) can be separated from the connection end (101), wherein the handpiece (100) is designed such that the motor (110) remains on the connection end (101) after uncoupling the housing (104), and the handpiece has a rotary clamping device (120) in which the rotary tool (210) can be attached.

A dental handpiece system includes a dental handpiece for operating a dental burr and providing a stream of water to the dental burr for cooling a tooth being acted upon by the dental burr. The dental handpiece further includes a flush water port for providing a flush water stream that is directed away from the dental burr to allow the dentist to flush a work site in a patient's mouth. The dental handpiece can also include an air outlet for providing a stream of air that is also not directed to the dental burr and that can be used to dry other dental instruments as well as work sites in the patient's mouth.
