Device for sucking up and collecting bone particles

Abstract

Abstract This invention concerns a device for sucking up and collecting bone particles, such as bone meal, and bore chips from cooling and/or rinsing liquids during dental interventions in implantology and in the field of bone regeneration periodontology. Said device essentially consists of an aspirator tip (1), an adapter (7), and a housing with an upper part (2), a lower part (4) and a filter sieve (3). A conical intake port (2b) leads past a sharp-edged transition section (2c) into a dome-shaped cavity (2d) in the upper part (2). A funnel-shaped cavity (4b) in the lower part (4) adjoins it. Between the cavities (2d; 4b), a filter sieve (3) is located. The upper part (2) is provided with a collar (2a) into which an O-ring (5) fits. The lower part (4) is provided with a recess with a wall (4a) and with a connecting port (4c) for a hose (6). The collar (2a), the O-ring (5) and the wall (4a) form the housing closure in which the filter sieve (3) is seated. The upper part (2) and the lower part (4) are made of pure titanium. The filter sieves(3) are graded in degree of fineness and soldered through the rim. The adapter (7) is provided with different inlet ports for different aspirator tips.
