  • Handpiece tip
    Publication number: 20050277897
    Abstract: A handpiece tip having a seal, a raised ridge or snap lock and a stop. Such a construction allows the infusion sleeve to be pushed onto the handpiece tip without threading. The raised ridge locks the infusion sleeve into place. The seal prevents leakage from the connection. The stop prevents the infusion sleeve from being pushed too far onto the handpiece tip. The handpiece tip can be used with conventional internally threaded infusion sleeves.
