The utility model relates to an
oral cavity flushing and sucking device with an adjustable included angle, which comprises a water inlet piece, a liquid sucking piece and a central column, the
tail part of the water inlet piece and the
tail part of the liquid sucking piece are respectively provided with a first connecting piece and a second connecting piece, and the first connecting piece is coaxially and rotatably connected with the second connecting piece through the central column; and a clamping module is arranged outside the central column. The utility model has the beneficial effects that when the mouth width of a patient is small, the first connecting piece and the second connecting piece are pressed to be close to one ends of the water inlet piece and the liquid absorption piece, so that the first connecting piece and the second connecting piece rotate around the central column, the included angle between the water inlet piece and the liquid absorption piece is reduced, and the
oral cavity of the patient with the
small mouth width can be placed; the device can adapt to the
mouth opening widths of different patients, is particularly suitable for patient groups with
small mouth opening widths, effectively solves the problem of insufficient suitability of instruments in the prior art, and remarkably improves the operation convenience and the safety of the patients.
