A tubing connector for integrally connecting an irrigation line, an aspiration line, and a conductor to a proximal portion of an ultrasonic surgical handpiece. The tubing connector includes a base including proximal and distal regions. First and second lumens through the base each extends from the proximal region to the distal region to create respective first and second fluid pathways to the proximal portion of the handpiece. The first lumen includes a first coupler proximate the base proximal region configured to receive the irrigation line, and the second lumen includes a second coupler proximate the base proximal region configured to receive the aspiration line. The base defines a groove in an outer perimeter that extends between the proximal and distal regions and is configured to receive the conductor. The tubing connector is configured to reduce strain of the irrigation line and the aspiration line when coupled to the handpiece.

Ultrasonic surgical handpiece assembly

An ultrasonic surgical assembly for use with a surgical handpiece to provide air cooling of an ultrasonic tip. An ultrasonic tip comprises a shaft and a cutting portion. The tip comprises a first side and a second side that are substantially planar and a cutting head. The tip is removably coupled to a horn. The assembly comprises an irrigation sleeve defining a lumen. The sleeve at least partially surrounds the shaft, defines an inlet aperture, and comprises a conduit in fluid communication with the lumen. The conduit has an outlet aperture and is configured for being connected to a liquid source. The tip comprises a sealing member coupled to its outer surface and has a first bore defining an air inlet disposed proximal the sealing member and a second bore extending from the proximal end of the shaft to the first bore to form a fluid bath therebetween.

Ultrasonic surgical assembly with air cooling broad knife and irrigation sleeve

An ultrasonic tip and methods of operating the same. The ultrasonic tip comprises a shaft including a base and a flexible body. The body comprises a first portion and a second portion. The body is coupled to the base at the first portion and extends from the first portion to the second portion along a longitudinal axis. The second portion includes a cutting portion comprising a neck, and a head extending radially from the longitudinal axis. The head is coupled to the neck. A circular aperture is disposed between the head and the neck to define an inner circumferential surface. The head and the neck form an outer circumferential surface comprising a plurality of cutting teeth, the outer circumferential surface having a first thickness at the head that is greater than a second thickness at the neck.

Ultrasonic cutting tip for lumbar procedures

An ultrasonic tip for use with a surgical handpiece to produce both longitudinal and torsional motion. The ultrasonic tip comprises a shaft having a longitudinal axis extending between proximal and distal ends having respective first and second diameters with the first diameter greater than the second diameter. The ultrasonic tip also comprises a cutting feature coupled to the distal end of the shaft. The shaft defines an aspiration lumen that extends along the longitudinal axis of the shaft. A protrusion on the shaft is positioned between the distal end and the proximal end of the shaft. A portion of the protrusion having a third diameter, and the third diameter is less than the first diameter and the third diameter is greater than the second diameter. An aperture is defined by the protrusion and in fluid communication with the aspiration lumen, and the protrusion reinforces an area surrounding the aperture.

Ultrasonic tip with protrusion defining a preaspiration hole

Ultrasonic knife

An ultrasonic surgical instrument assembly including an irrigation sleeve assembly defining a lumen and an ultrasonic tip at least partially disposed within the lumen of the irrigation sleeve. The irrigation sleeve assembly may comprise a hub and an irrigation sleeve coupled to the hub. The irrigation sleeve may comprise an inner sheath and an outer sheath, both extending distally from the hub. The outer sheath may surround at least a portion of the inner sheath to define an irrigation passageway between the outer sheath and the inner sheath configured to deliver irrigation fluid to the surgical site. The distal end of the inner sheath may extend beyond the distal end of the outer sheath. Each of the inner and the outer sheath may be coupled to the hub by an annular sealing member configured to create fluid-tight seal between the hub and the respective inner and outer sheath.

Ultrasonic surgical irrigation sleeve and related assemblies

Sleeve for an ultrasonic handpiece

The present disclosure relates to an ultrasonic surgical handpiece assembly comprising a surgical handpiece for use with an irrigation sleeve and ultrasonic tip. The surgical handpiece may comprise a piezoelectric transducer disposed within a housing and configured to manipulate the ultrasonic tip. One or more lumens and/or a flex circuit including an antenna may be disposed within the surgical handpiece housing. The lumen(s) may be configured to provide irrigation and/or aspiration to the irrigation sleeve and/or ultrasonic tip. The irrigation sleeve may comprise a second antenna configured to communicate with the ultrasonic handpiece antenna. The irrigation sleeve may further comprise and an alignment and/or coupling feature configured to removably secure the irrigation sleeve to the housing and orient the second antenna relative to the ultrasonic handpiece antenna. The irrigation sleeve may further comprise a lumen for supplying irrigation and/or aspiration to the ultrasonic tip.
