Dental instrumentation unit

摘要

An instrumentation delivery unit which supports hand-held dental instruments. In one example first and second housing members form a sealed chamber. When the members are separated, access is permitted to the interior of the chamber, e.g., for maintenance purposes. A first portal suitable for connection to a vacuum line provides a partial vacuum in the chamber, and second portals provide connection via second vacuum lines between the chamber and dental devices to operate the devices. The housing includes hand piece holders each of an initial diametric size for receiving hand pieces up to a maximum diametric dimension, with one of the hand piece holders formed along two adjoining ones of the housing members. The adjoining housing members secure inserts between one another to provide a second diametric size smaller than the initial diametric size to thereby selectably accommodate hand pieces having a smaller diametric dimensions.

1. A dental instrumentation delivery unit of the type which supports hand-held instruments for use by a dentist or dental assistant in performing dental procedures via the use of a hand-held instrument, comprising:
a housing configured to be supported by a dental delivery arm in a position adjacent a dental chair and including a plurality of members configurable in an open position and a closed position; the housing including first and second members which, when configured in the closed position, provide a sealed chamber therein and, when configured in the open position, permit access to an interior portion of the chamber, and the housing including, along an exterior portion thereof, a plurality of hand piece holders each of a first diametric size for receiving hand-held instruments up to a maximum diametric dimension; the chamber including a first port suitable for connection to a vacuum line to create a partial vacuum in the chamber, and at least a second port providing a connection via a second vacuum line between the chamber and a first hand-held instrument to operate the instrument when a partial vacuum is applied through the second vacuum line; and at least one insert secured to the housing at one of the hand piece holders and defining an arcuate slot of a second diametric size smaller than the first diametric size for selectively accommodating a hand-held instrument having a smaller than maximum diametric dimension, wherein the at least one insert comprises a plurality of inserts each having a shoulder defining first and second shoulder portions of generally the same size, but having slots of varying diametric size.
