Medical dental rinsing instrument (1) comprises vibration part (30), and injection part (20), which can be coupled together. The injection part comprises a hollow cylindrical body (21), with an input outer end (23) and a narrow needle (25). In the interior of the body is an axially displaceable piston (22), which at its free side turned away from the injection mouth is provided with a coupling component for connection with the vibration part, particularly a screw thread. The vibration part comprises a housing (31) which at one outer end is provided with a coupling component (32) for connection with the injection part, preferably a screw thread. In the housing is fitted a vibration generator (34), preferably a motor. Also incorporated is a battery chambe (39) for the receipt of a battery (35), which feeds electrical current to the vibration generator. In the housing is fitted a switch (36) operable by a user for activation of the vibration generator. |
