An instrument holder device, comprising:
- an instrument, said instrument being for dental work;
- a holding means, said holding means having a first portion and a second portion, said first portion consisting of at least two nibs and cylindrical-like part, said nibs being located at the distal end of said first portion, said cylindrical-like part being located immediately adjacent to and integral with said nibs, said cylindrical-like part having external screw threads thereon, said nibs being spaced apart around the periphery of said distal end of said first portion, said nibs having a clearance space between the sides thereof and the sides of adjacent nibs, said nibs being tapered on the exterior of the distal end thereof, said holding means having a continuous passageway therethrough, said first portion and said second portion being adjacent to, a continuation of, and integral with, each other, said passageway being continuous through both said first and second portions, said passageway having a counter-bore, said counter-bore extending inwardly from the distal end of said nibs, one end of said instrument being removably inserted into said counter-bore, said instrument having a mounting end thereon configured to fit withing said counter-bore, said second portion having external screw threads thereon, said external threads on said second portion being located on the distal end thereof opposite to said distal end of said first portion;
- and
- a locking means, said locking means being configured as a hollow, cylindrical-like body, said body having a first end and a second end, said body having a passageway therethrough, said passageway having internal screw threads in said passageway at said first end of said body, said internal screw threads mating with said external screw threads on said cylindrical-like part of said first portion of said holding means, said body of said locking means being reduced in configuration in relation to said passageway therethrough at said second end thereof, said first end of said holding means being removably inserted into said first end of said locking means and removably assembled thereto by engaging said external screw threads on said first portion of said holding means with said internal threads in said locking means, thereby locking said end of said instrument within said nibs of said holding means, said locking means being removably affixed to said holding means to secure said instrument in said holding means, said instrument being locked in place by tightening said locking means on said holding means, whereupon said tapered ends of said nibs interface with the internal periphery of said passgeway and tighten upon said mounting end of said instrument as said locking means is further tightened, a portion of the exterior of said locking means being configured to provide a suitable surface for attachment of a wrench means for tightening said locking means when assembled with an instrument therein, said passageway in said holding means cooperates with the internal configuration of said locking means so as to formulate a communicating series of passageways within said instrument holder device for the passage of a solution therethrough, said series of passageways consisting of said passageway through said holding means, including said counter-bore, the opening between spaced apart nibs, and the passageway in said locking means, said solution being discharged axially along said instrument.
