Filed:

Sep 28, 2000

Appl. No.:

09/675339

Inventors:

Thomas B. Sutton - Irvine CA
Kenneth E. Kadziauskas - Las Flores CA
Paul W. Rockley - Laguna Niguel CA

Assignee:

Allergan, Inc. - Irvine CA

International Classification:

A61B 1720

US Classification:

604 22, 604 35, 604 43

Abstract:

Phaco tip apparatus for a phacoemulsification/irrigation and aspiration handpiece having an ultrasonic drive assembly includes a needle having a tip for emulsifying a cataractic lens and a lumen for aspirating emulsified lens. A compressible sleeve establishes an annular passage around the needle and enables irrigation fluid to pass into an eye through a cornea/sclera wound while cooling the needle. The compressible sleeve includes a wall configuration for controlling compression of the sleeve in order to cause the compressible sleeve to shape and conform to the cornea/sclera wound and limit fluid egress from the wound. A bypass port, disposed in said needle and under said compressible sleeve, establishes fluid communication between the lumen and the annular passage in order to enable irrigation fluid to pass into said lumen upon clogging of the tip, thus providing fluid surge protection. A depending member disposed within said compressible sleeve limits compression of opposing walls of said compressible sleeve in order to prevent contact of said compressible sleeve with the needle, maintain the annular passage flow of irrigation fluid past the needle and prevent the compressible sleeve from closing the bypass port.

International Classification:

A61B 1720

US Classification:

604 22, 604 27, 604 35, 604 43, 604187, 604239, 604264, 606167

Abstract:

A phacoemulsification needle includes a body having an aspiration lumen therethrough along with a hub disposed at a proximal end of the needle body for engaging an ultrasonic handpiece in order to couple ultrasonic energy into a needle body. A tip is provided at a distal end of the needle body for penetrating tissue to be emulsified and a conical ultrasonic surface disposed at the tip is provided for focusing ultrasound in tissue beyond an end of the tip in order to promote cavitation in tissue beyond the tip end. The conical ultrasonic radiation surface extends from the lumen to the end of the tip.

International Classification:

A61M 100

US Classification:

604 30, 604 34

Abstract:

A tubing management manifold for a surgical instrument console for controlling fluidflow to and from a surgical instrument includes a housing having a front and opposing sides, and sides, for enabling tubing to be disposed therein and across the housing between the opposing sides. Ports, disposed in the housing front are provided for enabling access to the tubing, disposed across the housing, in order to control fluid flow through the tubing. A tubing capture is disposed on one of the opposing sides, aligned with one of said openings and extending outwardly from said housing, for grasping the tubing in order to prevent unwanted dislodgement of the tubing from said housing.

International Classification:

A61M005/32

US Classification:

604272, 606170, 604294

Abstract:

A multipurpose phacoemulsification needle includes a needle body having a lumen therethrough for aspiration of fluids and tissue. A needle body includes a proximal end adapted for attachment to a phacoemulsification handpiece and a tip portion disposed at a distal end of the needle body. The tip portion includes a truncated hemisphere having a flat surface thereon and a port disposed in the flat surface. The truncated hemisphere includes a rounded surface of sufficient area to enable capsule polishing and when driven in an ultrasonic mode, the needle is also suitable for irrigation and aspiration as well as phacoemulsification of lens tissue.

Abstract:

A device for achieving high vacuum stability during phacoemulsification surgery includes a main aspiration line connected to a vacuum source which enables a fluid flow from a phacoemulsification handpiece tip to a drainage reservoir. A first tubing segment is provided in the main aspiration line along with a second tubing segment generally parallel to the first tubing section and a valve disposed in the second tubing segment regulates fluid flow through the second tubing segment in order to limit vacuum surge in the main aspiration line upon clearing of an occlusion in the phacoemulsification handpiece tip.
