摘要： A dental suction tool has a disposable sanitary plastic suction tip to prevent cross contamination from one patient to the next. Additionally, a light source such as a fiberoptic bundle with or without a ring light is provided on the interior of the dental suction tool to provide light to the end of the plastic disposable suction tip. Illumination from the ring light or directly from the fiberoptic bundle is transmitted along the length of the suction tip and is emitted from the end thereof to illuminate the oral cavity during dental procedures.

摘要： A syringe tip (114) is locked into a three-way dental handpiece body (12) by means of a syringe tip locking assembly (115) that screws into a threaded receiver (13) in the body of the handpiece (12). The locking assembly (115) comprises an adaptor (120) that has a central tapered male member (121) that receives one end of the syringe tip (114), a gripping member (140) that snaps over a raised lip (128) on the end of the adaptor body (120) and a locking cap (130) that screws onto the adaptor (120) and over the gripping member (140). The gripping member (140) includes a plurality of gripping fingers (11) that engage the syringe tip (114) and the locking cap (130) effects the tightening of the gripping fingers (141) into the syringe tip (114). The locking assembly (115) both applies a positive gripping action to the syringe tip (114) and also pulls the syringe tip (114) onto the tapered male member (121) to securely hold the syringe tip (114) in the adaptator (120) during use by the dentist. The gripping member (140) is captivated onto the raised lip (128) of the adaptator (120) to prevent inadvertent separation of the pieces.

摘要： A syringe tip adaptor (20) for connecting a syringe tip (14) to a handpiece body (12) comprises channel means (62) for providing an air passage from the handpiece body (12) through its cylindrical body (20) and into an air passageway (34) in the syringe tip (14). The channel means (62) is generally radially disposed relative to the hollow interior of the cylindrical body (20). An elongated tapered male connector (21) has an axial opening (48) therethrough adapted to cooperate with a central passageway (32) in the syringe tip (14) to provide a water passageway from the handpiece body (12) through the adaptor (20) and into the syringe tip (14). When the syringe tip (14) is mounted on the tapered male connector (21), the syringe tip (14) will be tightly held on the tapered male connector (21) to prevent axial rotation of the syringe tip (14) and to ensure that the air and water passageways do not leak into each other.

摘要： A dental suction tool has a disposable sanitary plastic suction tip to prevent cross contamination from one patient to the next. The tip has a bevel at the proximal end. Additionally, a light source such as a fibreoptic bundle with or without a ring light is provided on the interior of the dental suction tool to provide light to the end of the plastic disposable suction tip. Illumination from the ring light or directly from the fibreoptic bundle is transmitted along the length of the suction tip and is emitted from the end thereof to illuminate the oral cavity during dental procedures.

摘要： A dental syringe tip handpiece assembly includes a plastic syringe tip mounted in an adaptor for connection to the handpiece. On the interior of the adaptor at a location adjacent the end of the syringe tip, a source of light is provided. Light from the light source will be transmitted down the length of the syringe tip and emitted from the end thereof. By positioning the end of the syringe tip in the patient's oral cavity, the dentist can provide illumination in the oral cavity so that various dental functions can be more easily and accurately performed.

摘要： A clear rigid plastic syringe tip (14) has a central water passageway (32) and three arcuate section air passageways (34) disposed circumferentially about the water passageway (32). A novel adaptor (20) is used to mount the syringe tip (14) to the handpiece body (12). Alternatively, the syringe tip (114) has an extension (113) that mounts the syringe tip (114) into an adaptor (120) which holds the assembly in the handpiece body (12). Alternatively, the adaptor (120) is provided with a coupling device (180) for joining the syringe tip (214) to the adaptor. (120).
