Abstract: A manual syringe (10) includes a disposable syringe cylinder (12), a disposable piston (14) and a disposable piston rod (16). The piston rod (16) includes a position encoder (18). A piston-position indicator means (22) coupled to the position encoder (18) is fixedly assigned to the syringe cylinder (12). The piston-position indicator means (22) is reusable and is adapted to be detached from the syringe cylinder (12).

Abstract: The device comprises a first holding device (10) which is attached to a syringe barrel (11) of a syringe, and a second holding device (25) which is attached to a plunger barrel (21) of the syringe. Both holding devices are linearly guided relative to each other. One of the holding devices carries a dial gage (31) comprising a rotary shaft (30). Said rotary shaft (30) is in engagement with a toothing (29) of the other holding device. An indicator (32) indicates, with a high resolution, the movement of the plunger rod relative to the syringe barrel such that a highly accurate fine dosing of a liquid discharged from the syringe can be realized.

Abstract: The invention relates to a suction cannula (10) for sucking biological tissue from a human body, comprising a suction tube (12) with a suction aperture (20), the suction tube (12) further comprising a cleaning aperture (22). Further, a cleaning aperture closure (38) is provided which, in its closing state, closes the cleaning aperture and, in its opening state, releases the cleaning aperture (22).

Abstract: The liposuction device (10) for removing subcutaneous fatty tissue (12) comprises a suction cannula (16) with suction openings (22) for sucking the subcutaneous fatty tissue (12) and an injection line (18) with an injection opening (20) for injecting a working fluid. The injection opening (20) is placed on the front end of the injection line (18) and is provided in the shape of a slit so that the working fluid exits in the shape of a fan (21). The width of the slit of the injection opening (20) is less than 1.0 mm. This constricts the injection opening so that the use of the working liquid is reduced to a justifiable quantity, at the same time, the exiting working fluid fan guarantees a uniform and effective removal of subcutaneous fatty tissue.
