Dental syringe tip and adaptor

A syringe tip assembly comprising

• a) a syringe tip comprising an elongated cylindrical rigid plastic member having a first central passageway throughout the entire length of the cylindrical member, said first central passageway being generally circular in cross-section, and a plurality of second passageways disposed circumferentially about the first central passageway, said second passageways being generally arcuate in cross-section and extending substantially the entire length of the tip.
• b) an adaptor means for mounting the syringe tip to a handpiece body, and
• c) a syringe tip coupling device comprising a mounting stem having an internal passageway for mounting the syringe tip coupling device to the adaptor means, an expanded shoulder on one end of the mounting stem and a hollow tip member having an internal passageway mounted to the expanded shoulder for mounting the syringe tip on the coupling device.

The syringe tip coupling device of claim 33 wherein the mounting stem has a length in a range generally of 0.165-0.185", the expanded shoulder has a length in a range generally of 0.020-0.030" inches and the hollow tip member had a length in a range generally of 0.615"-0.635".

A syringe tip assembly comprising:

• a) a syringe tip comprising an elongated cylindrical rigid plastic member having a first central passageway throughout the entire length of the cylindrical member, said first central passageway being generally circular in cross-section, and a plurality of second passageways disposed circumferentially about the first central passageway, said second passageways being generally arcuate in cross-section and extending substantially the entire length of the tip, and
• b) a syringe tip extension having an interior passageway mounted to the elongated member, and
• c) means for mounting the syringe tip and syringe tip extension to a handpiece body.
