Dental suction device with a camera

A handheld dental suction device (10) formed as a single tubular hollow base body (12), having an inner surface (14), an outer surface (16), a longitudinal axis (X-X), and a connection opening (18) for a hose, the tubular hollow base body 12) comprising:

• an objective lens (24) in the course of an extent of the base body (12), operable to take an image or a video, comprising;
• a connection to a monitor (40), wherein the monitor displays the image taken by the objective;
• and a zoom controller comprising a slide control of the objective lens to perform a zooming function on an image taken by the objective lens;
• wherein the slide control is operable during treatment using a single finger of a user;
• wherein the objective lens (24) is mounted in an inner surface of the suction device (10) below a suction opening (20) which is used for suctioning liquids and particles from an oral cavity of a patient and along the longitudinal axis (X-X);
• wherein a flowing direction of air to be suctioned off through the tubular hollow base body (12) is parallel to the longitudinal axis (X-X) and over the objective lens (24) in the tubular hollow base body (12);
• wherein the objective lens (24) is disposed in an interior of the tubular hollow base body (12) in relation to a z-axis -behind and below the suction opening (20) of the tubular base body (12) as viewed in a flowing direction of the air to be suctioned off in such a way that the suctioned air is guided into and through the tubular hollow base body (12) over the objective lens (24) which effectively prevents fogging.
