ASPIRATION FITTING ADAPTOR Abstract The disposable adaptor to permit aspiration and/or irrigation fluid to pass through an ultrasonic surgical instrument without permitting leakage of the fluid from or into the interior of the instrument. The adaptor includes a generally annular housing defining a lumen for receiving the horn of the ultrasonic instrument and having inner seals forming a seal between the confronting surface of the adaptor and horn for prohibiting leakage along the exterior wall of the horn and an outer seal for forming a tight seal between the confronting surface of the adaptor and the instrument shroud for prohibiting leakage along the exterior surface of the adaptor. The adaptor includes a flange at its distal end with a circumferential groove extending partially about the adaptor and cooperating with a mating projection on the distal end of the instrument shroud to provide rotational orientation for the adaptor with respect to the shroud.
