US 4,988,334 A · Ultrasonic surgical system with aspiration tubulation connector

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.

In combination with an assembly of an ultrasonically vibratable tip having an exposed aspiration port adjacent a proximal end thereof and communicating with an aspiration passage formed therein, said tip being connected at the proximal end to a source of ultrasonic vibrations in a handpiece in an ultrasonic surgical aspiration system so that at least a portion of said tip is enveloped by a nosecone which is connected to said handpiece and has a slot in register with a slot in said vibration source, said slots when in register permitting access to said exposed port of said tip when assembled to an exterior of said assembly, the improvement comprising:

a removable aspiration tubulation connector having an inlet port structurally adapted for connection to the aspiration port of said tip and an outlet port structurally adapted for connection to aspiration tubing at the exterior of said nosecone;
said removable aspiration tubulation connector being structurally adapted to define an aspiration fluid passage through said slots in register from said inward port to said outward port;
said removable aspiration tubulation connector having a transition part structurally adapted to removably fit within said nosecone slot in a secure relationship when said inlet port is secured to said aspiration port said aspiration tubulation connector having a body portion sized and shaped to have a releasably secure engagement with said nosecone slot, and
said outlet port lying along an axis exterior to said handpiece, said axis being axially offset relative to the axis of said aspiration port of said tip and said inlet port on said connector.

An ultrasonic surgical system comprising:

a nosecone defining a nosecone chamber having a longitudinal axis and a nosecone opening laterally disposed relative to the longitudinal axis and passing from the exterior of said nosecone into said nosecone chamber;
an ultrasonically-vibrated surgical tip defining a tip bore therethrough and connected at one end thereof to a longitudinal end of said nosecone and extending forwardly therefrom;
said surgical tip having an aspiration tip disposed in said nosecone chamber;
an aspiration tubing communicatable with said tip bore and with a source of vacuum;
an aspiration tubulation connector insertable at least partially through said nosecone opening into said nosecone chamber and structurally adapted for operatively connecting said aspiration tubing to said aspiration tip;
said aspiration tubulation connector including structural means comprising an outer body portion secured to said aspiration tubing and a transition portion connected thereto and insertable through said nosecone opening into said nosecone chamber and defining an outward port for mating to said aspiration tip by pushing it theretowards;
said outer body portion and said transition portion defining a generally rigid structure and a curved aspiration fluid passageway of generally fixed configuration therethrough and positionable between said aspiration tubing and said aspiration tip, said outer body portion being configured to have a releasably secure engagement with said nosecone opening.
