TL;DR: In this paper, a vibratable tip for ultrasonically disintegrating tissue in a surgical procedure and for aspirating the disintegrated tissue and fluids away from the surgical site through an opening in the tip was presented.

TL;DR: An ultrasonic surgical aspirator with an improved irrigation/aspiration manifold and components to facilitate quick connections of the irrigation and aspiration lines to a handpiece is described in this article, where an ultrasonic vibrator and a nosecone are combined with a handle assembly.

Abstract: An ultrasonic surgical aspirator having an improved irrigation/aspiration manifold and components to facilitate quick connections of the irrigation and aspiration lines to a handpiece. In combination with a handle assembly having an ultrasonic vibrator for vibrating an ultrasonic tip and a nosecone, a nosecone extension defining a rotating joint for connection to the nosecone in an articulating joint for connection to a rigid or flexible flue is provided. The nosecone extension further defines an irrigation cowl having an irrigation port for receiving an irrigation connector for connecting the irrigation fluid to the nosecone extension for passage of irrigation fluid through the nosecone extension and a flue about the surgical tip. An aspiration tubulation connector adapted to securely fit a slot through the nosecone and nosecone extension connects an aspiration port on the tip to the aspiration tube for connection to a pump into a discard area. An alternative manifold assembly includes a nosecone extension adapter defining a rotating joint for connection to the nosecone in a cylindrical portion for connection to an extender sheath, the opposite end of which is connected to a flue adapter defining an articulating joint for connection to a flue. Such an alternative manifold assembly is particularly adapted for use in elongated and curved tips with extenders. The detailed structure of the aspiration tubular connector and the irrigation connector is also shown.

TL;DR: In this article, an ultrasonic surgical aspirator with an improved irrigation/aspiration manifold and components to facilitate quick connections of the irrigation and aspiration lines to a handpiece is presented.

TL;DR: In this paper, a torquing wrench has a tightening head and an untightening head on the same body, wherein the tightening head permits torquesing of the tip and extender to a predetermined tightening torque in cooperation with a socket having a central bore therethrough so that the wrench and socket may be slid over an axially elongated combination and used at a point intermediate along the length thereof.
